Definitions
- the present invention pertains to a surgical instrument for tying a knot in a length of suture at a remote location and the method of' using the instrument in tying the knot.
- a common characteristic of many known surgical knot-tying instruments is that they are very complicated to operate and time consuming to set up prior to their use.
- many prior art surgical knot-tying in ⁇ struments are used in a procedure that involves first tying the knot in a length of suture remote from the surgical location and then moving the loose knot along the length of suture material to a position proximate to the surgical location before the knot is tightened at the surgical location.
- the present invention overcomes disadvantages commonly associated with prior art surgical knot-tying instruments by providing a simplified surgical instrument for tying a knot in a length of suture proximate to a surgical site.
- the surgical instru ⁇ ment of the present invention may be employed in either open incision or laparoscopic surgery procedures to posi- tion a needle and a length of suture material proximate to a surgical location and to form one or more stitches with the length of suture material at the surgical loca ⁇ tion, and then to tie a knot in the length of suture material at the surgical location where the knot is formed from two or more throws of the suture material.
- the instrument is basically comprised of an elon ⁇ gate rod having opposite first and second ends.
- the longitudinal length of the rod is designed to enable the first end of the rod to be inserted through a convention- al, laparoscopic cannula to position the rod first end proximate to a surgical location or site within a body cavity accessible by the cannula.
- the second end of the rod projects from the cannula where it is grasped manu ⁇ ally to enable manipulation of the rod first end within the body cavity.
- the rod has a shortened longitudinal length and is connected to an elongate handle that enables manipulation of the rod within the body cavity through a cannula by manual manipulation of the handle.
- the rod is detachable from the handle for its removal and disposal after use and replacement by a like rod on the handle.
- the first end of the rod is provided with an indentation or slot that extends into the interior of the rod from the rod's exterior surface.
- a length of suture material is provided on the rod first end.
- the length of suture has a needle secured to its first end and the second end of the suture is secured to the second end of the rod or to the handle.
- the length of suture is wrapped around the first end of the rod in a specific pattern that provides a plurality of loops of the suture material around the first end extending over the slot formed in the rod.
- a portion of the suture's length extends from the last of the plurality of suture loops formed on the rod first end to the needle at the first end of the suture.
- Means are provided on the first end of the rod for releasably holding the needle to the rod first end.
- a magnet is encased in the material of the rod adjacent the rod first end. The magnet attracts the needle to the rod end and holds the needle in position on the rod end where it may be easily removed.
- the first end of the rod is positioned proximate to a surgical location by inserting the rod end into an open incision or by inserting the rod first end through the interior of a cannula providing access to a body cavity.
- the needle is removed from its magnetic attachment to the rod either manually or by gripping the needle with a laparoscopic grasper.
- One or more stitches are made in the desired positions at the surgical location and in preparation to form a first throw of a knot in the suture material, the needle is inserted into the slot in the rod first end beneath the first loop of suture material formed on the rod end. The needle is held in this position beneath the first loop of suture by the magnetism of the rod first end.
- the needle is released by the grasper and then retaken by the grasp ⁇ er at the distal end of the needle projecting from be ⁇ neath the first suture loop.
- the needle and the first end of the suture material are then pulled from the slot and from beneath the first suture loop causing the first loop to move off the first end of the rod.
- the first loop moves down the length of suture toward the stitch made at the surgi ⁇ cal location, forming a first throw of a knot in the suture material securely closing the stitch.
- This proce ⁇ dure may be repeated as many times as there are suture loops formed on the rod first end to form a knot of any desired number of throws.

- Figure 13 shows a partial perspective view of a further embodiment of the invention.
- a first embodiment of the surgical instrument 12 of the present invention is shown in Figures 1 and 4.
- the instrument is basi ⁇ cally comprised of an elongate rod 14, a length of suture material 16 secured to the rod, and a needle 18 secured to the length of suture material.
- the elongate rod has opposite first 20 and second 22 ends, or left hand and right hand ends respectively, adjacent opposite first 24 and second 26 end faces, or left and right end faces, as viewed in Figures 1 and 4.
- a hollow interior bore 28 extends longitudinally through the rod 14 between its end faces 24, 26.
- the interior and exterior diameter dimensions of the rod 14, as well as its longitudinal length between end faces, may vary depending on the intended application of the instrument.
- the instrument is designed for use with both open inci- sion surgery and laparoscopic surgery and the rod 14 of the instrument may be dimensioned so that it can be easi ⁇ ly inserted through the interior of a cannula in laparoscopic surgery applications. Additionally, the lateral dimensions of the instrument rod 14 may be enlarged to further facilitate its use in open incision surgical operations.
- the dimensions of the rod 14, su ⁇ ture material 16, and needle 18 shown in the drawing figures are not to scale and are not proportionate but are enlarged in Figures 1 and 4 to better illustrate the component parts of the invention and their relationship to each other. Moreover, it is not necessary that the instrument rod have the cylindrical configuration shown in Figures 1 and 4.
- a slot 30 is formed through the exterior surface 32 of the rod adjacent its first end 20 forming a recess or indentation into the rod from the exterior surface to the interior bore 28. As seen in the drawing figures, the slot 30 extends longitudinally from the first end face 24 of the rod along a portion of the rod's length.
- a second smaller slot 34 or slit is formed in the second end 22 of the instrument rod extending along a portion of the longitudinal length of the rod from the second end face 26.
- the length of suture material 16 has opposite first 36 and second 38 ends with the first end 36 of suture material being secured to the needle 18 in a con ⁇ ventional manner.
- the total length of the suture materi ⁇ al between its first and second ends may vary depending on the intended application of the surgical instrument of the invention, as will be explained.
- the second end 38 of the suture is secured adjacent the rod second end 26 by inserting the suture into the narrow slot 34.
- the second end 38 of the suture may be secured to the instrument rod 14 in any equivalent manner, or may be manually held adjacent the rod second end in use of the surgical instrument.
- the length of suture 16 extends from the instrument rod second end 22 along the exterior surface of the rod to ⁇ ward the rod first end 20 and is wrapped in several loops 42, 44, 46, 48, 50, 52 at the first end 20 of the rod. From the last of the plurality of loops, the suture mate ⁇ rial extends to its first end 36 secured to the needle 18.
- each of the loops of suture material are wrapped around the exterior surface of the rod in a specific configuration that enables indi ⁇ vidual loops to be spaced from each other along the rod first end 20 and also enables individual loops to be manipulated to slide along the longitudinal length of the rod first end without causing adjacent loops to move along the length of the rod.
- the suture material 16 may be formed in a variety of different loop configurations on the rod first end 20 that enable the plurality of suture loops to be spaced from each other as shown in Figure 1 and allow individual loops of suture material to be manually moved longitudi ⁇ nally over the exterior surface of the rod without caus ⁇ ing adjacent loops to be moved.
- the specific configuration of the suture loops shown in Figure 1 is produced by forming a first bend 54 in the suture material 16 as it extends longitudinally over the exterior surface of the rod 14 from the second end 22 toward the first end 20 of the rod. From the first bend 54, the suture material extends laterally relative to the rod and is wrapped one complete revolu ⁇ tion around the exterior surface of the rod back to the first bend 54. The suture material is then formed in a second bend 56 around the first bend 54 of the suture and again extends longitudinally along a portion of the rod's length, thereby completing the formation of the first loop 42 in the suture material.
- the subsequent or adja ⁇ cent loop 44 is formed in substantially the same manner as the first described loop 42.
- a first bend 58 is formed in the suture material and the suture extends from the first bend laterally around the exterior surface of the rod 14 one complete revolution back to the first bend of the second loop.
- a second bend 60 is formed in the suture material around the first bend 58 of the second loop.
- the suture material continues to extend longitudinally toward the rod first end 20 from the second bend 60, thereby com ⁇ pleting the second loop 44 of suture material formed on the exterior of the rod 14.
- the remaining pairs of loops 46 and 48, 50 and 52 are formed in the suture material as it extends toward the rod first end 20 in the identi ⁇ cal manner as the first pair of loops 42, 44 just described.
- first and second loops 42, 44 are substantially mirror images of each other, and the second and third loops 44, 46 are also substantially mirror images of each other.
- these first three loops of suture material may have been wound around the exterior surface of the rod 14 so that their configurations are substantially identical to each other, as are the first and third loops 42, 46.
- all of the loops of suture material could have been wrapped around the exterior of the rod 14 in sub ⁇ stantially the same configuration as the first loop 42 or all of the plurality of loops could have been wrapped in substantially the same configuration as the second loop 44 without departing from the intended scope of the claimed invention and without altering the operation of the invention or its method of use.
- a strip magnet 64 is encased in the material of the rod first end extending along one side of the first slot 30 as shown in Figure 4.
- the needle 18 is held securely in place at the rod first end 20 as shown in Figure 4.
- Alternate means of securing the needle 18 at the rod first end 20 may be employed in place of the strip magnet 64.
- the rod first end 20 may be formed without the strip magnet 64 and the needle 18 may be positioned between the suture loop 52 formed adjacent the rod first end face 24 and the exteri ⁇ or surface 32 of the rod to securely hold the needle in place.
- the needle may be given a curvature substantially equal to that of the rod exterior surface so that it may be positioned beneath the end loop 52 extending adjacent the rod exterior surface to its tip.
- the strip magnet 64 could be eliminated from its position adjacent the slot 30 and the needle 18 could be held in place relative to the rod by a conventional laparoscopic surgery grasper inserted through the rod interior bore 28 from its second end 22.
- the exterior diameter of the rod 14 would be dimensioned small enough to enable it to be inserted through the interior of a conventional laparoscopic cannula.
- the interior diameter of the rod bore 28 would be dimensioned sufficiently large to enable the insertion of a conventional laparoscopic grasper through the bore.
- the grasper would be inserted through the rod bore from the rod second end 22 with the jaws of the grasper positioned adjacent the rod first end 20. In this position of the grasper, the jaws would grip and releasably hold the needle 18 on insertion of the first end of the instrument rod through the cannula into the body cavity, and in subsequent manipulations of the nee ⁇ dle in forming throws of a knot according to the method of the invention yet to be described.
- Using the surgical instrument of the invention 12 in this manner also pro ⁇ vides the surgeon with a pair of laparoscopic graspers to use together with the instrument in forming stitches laparoscopically without the requirement of inserting more than a pair of cannulas into the body cavity.
- suture loops are formed in a length of suture material, and the longitudinal length of the first slot 30 is extended along the length of the rod so that it passes beneath each of the loops formed in the suture material.
- the number of suture loops may vary and the longitudinal length of the slot beneath the loops may also vary. In use of the invention, it is only necessary that the longitudinal length of the slot be sufficient to enable each of the plurality of loops formed in the su ⁇ ture material to extend over the slot.
- Figure 2 shows a variant embodiment of the rod 70 of the surgical instrument.
- the rod again has a cylindrical configuration; however, the rod does not have a hollow interior bore as in the first embodiment.
- the rod configuration shown in Figure 2 is solid with the slot 72 extending down into the interior of the material of the rod from the exterior surface 74.
- the slot 72 like the slot of the first embodiment, ex ⁇ tends for a portion of the longitudinal length of the rod from the rod first end face 76.
- the longitudinal length of the slot 72 is determined to enable the slot to extend beneath the plurality of loops formed in suture material (not shown) wrapped over the first end of the rod 70.
- the remaining component parts, i.e. the suture material and needle, of the second embodiment of the surgical instrument employing the solid rod 70 are substantially identical to those of the first described embodiment of Figures 1 and 4.
- Figure 3 shows a still further variant embodiment of the surgical instrument rod 78.
- the first end, or left hand end of the rod as viewed in Figure 3 may have the same tubular configuration of the first described embodiment of Figures 1 and 4 or may have the solid configuration of the rod shown in Figure 2.
- the rod has a slot 80 formed in its first end in the same manner as the previously described embodiments and a length of suture material is wrapped over the exterior surface of the rod and the slot with one end of the suture secured to the rod and the opposite end of the suture secured to a needle 82 in the same manner as the first described embodiments.
- the embodiment of Figure 3 differs from the previously de- scribed embodiments in that the longitudinal length of the surgical instrument is divided into two sections with the first section comprising the rod 78 and the second section comprising a handle 86. As shown in Figure 3, the second end of the rod 78 is detachably secured to one end of the handle 86 by a threaded connection 88. Other equivalent means of providing a releasable connection may also be employed.
- the longitudinal length of the instrument enables it to be used in both deep open incisions or in laparoscopic surgery as in the previously described embodiments.
- the ability of the rod 78 to be detached from the handle 86 enables the rod to be detached and disposed of after use and replaced on the handle by a like rod. With the con ⁇ figuration of the surgical instrument shown in Figure 3, once the length of suture has been used from one rod of the instrument the used rod may be detached from the handle and replaced with a new rod having a length of suture looped over its exterior surface.
- Figures 5-10 are schematic representations of the method of the invention employed in using the surgical instrument of the invention for tying a knot in a length of suture in a laparoscopic surgical operation.
- the drawing figures and their descriptions to follow only generally describe one use of the surgical instrument of the invention and are employed only to illustrate some benefits provided by the surgical instrument of the in ⁇ vention.
- Drawing Figures 5-10 and their descriptions to follow describe use of the surgical instrument of the invention in laparoscopic surgery forming a single stitch to close an incision.
- the description to follow is illustrative only and should not be interpreted as limiting the use of the surgical instrument of the invention to only laparoscopic surgical techniques or only use in forming one stitch in securing adjacent tissues together.
- the benefits provid- ed by the unique surgical instrument of the present in ⁇ vention suit it for use in a variety of different known surgical techniques and for use in forming both a single stitch and a line of stitching in body tissues.
- FIG 5 is a schematic representation of a view looking inside a body cavity toward an opening in a tis- sue 90 representing a defect to be repaired or mended by use of the surgical instrument of the invention in accor ⁇ dance with the method of the invention.
- the drawing figure and Figures 6-10 to follow illustrate a laparoscopic repair of the defect 90 in the tissue and a pair of trocars 92, 94 are shown already inserted through left and right flanks of the body into the cavity, respectively.
- Graspers 96 are shown inserted through the left trocar 92 into the body cavity and the first end of the surgical instrument rod 98 with the length of suture 100 wrapped thereover and the needle 102 secured to the suture are shown inserted through the right trocar 94.
- the needle 102 is shown releasably held to the first end of the instrument rod 98 by a magnet encapsulated in the material of the rod, as was explained earlier.
- the length of suture extending from the needle 102 to the first suture loop 104 formed on the rod end may be longer than that shown in Figure 5 to facilitate manipulation of the needle in producing a stitch through the defective tissue 90.
- the excess length of suture between the nee- die 102 and the first suture loop 104 may be spirally wound on the rod first end between the rod end face 106 and the first loop 104.
- the second end of the rod 98 (not shown) extending from the exterior end of the trocar 94 is manipulated to position the rod first end proximate to the surgical location or the defective tissue 90.
- the graspers 96 are then used to remove the needle 102 from its magnetic attachment to the rod end and a stitch is made through the tissue defect 90 at the surgical loca- tion. Only one stitch is shown being made in Figure 6; however, as explained earlier, the surgical instrument of the invention may be employed in forming a line of stitching to close a larger tissue defect.
- the needle and attached length of suture are passed through the tissue defect several times along the line in one direction and then are passed again through the tissue defect along a return line back to the position where the suture was first inserted through the tissue.
- the needle In preparation to form a first throw of a knot in the suture material, the needle is repositioned by the grasper in the slot in the first rod end with the needle extending beneath the first loop 104 of suture material formed on the rod end.
- Figure 4 shows in more detail the proper positioning of the needle in preparing to form the first throw of the surgical knot.
- the needle is held in this position beneath the first loop of the suture by the magnetism of the first rod end.
- the needle is then re ⁇ leased by the grasper 96 and then retaken by the grasper at the distal end of the needle, or the point end of the needle projecting from beneath the first suture loop 104 and out of the slot as viewed in Figure 8.
- the needle and attached suture material are then pulled from the instrument slot and from beneath the first suture loop 104 causing the first loop to move off of the first end of the rod as shown in Figure 9.
- the first loop 104 moves down along the length of suture attached to the needle toward the stitch made at the surgical location in the tissue defect 90, forming a first throw of a knot in the suture material securely closing the stitch, as shown in Figure 10.
- the above process is repeated with the needle and attached suture passing through the slot and beneath the second loop 106 of suture formed on the exterior of the rod first end.
- the second loop is pulled off the rod first end down the length of suture attached to the needle.
- the second loop arrives at the stitch formed by the first throw and forms a second throw of the knot at the stitch.
- the procedure is repeated a third time by inserting the nee- die beneath the third loop 108 of suture and pulling the needle from beneath the loop and from the rod first end to cause the third loop to move off the rod end and down the suture forming a third throw in the knot at the stitch.
- This procedure may be repeated as many times as there are suture loops formed on the rod first end to form a knot of any desired number of throws.
- the surgical instru ⁇ ment of the invention facilitates tying a knot in a length of suture material at a remote surgical location according to the method of the invention by enabling the positioning of the suture material proximate to the sur ⁇ gical location and by holding the suture material at the surgical location in a manner that enables one or more throws of a knot to be easily formed in the suture mate ⁇ rial.
- Figure 11 shows a still further embodiment of the rod 110 of the surgical instrument similar to the embodi- ment shown in Figure 3.
- the rod has substantially the same configuration as the embodiment shown in Figures 1 and 4 with the length of suture mate ⁇ rial 112 and the needle 114 affixed thereto looped over the exterior surface of the rod 110 in substantially the same manner as that described with reference to Figures 1 and 4.
- the rod 110 has a slot 116 formed in its first end in the same manner as the previously described em ⁇ bodiment of Figures 1 and 4 and the length of suture material is looped over the slot.
- the longitudinal length of the surgical instrument is divided into two sections, with the first section comprising the rod 110 and the second section comprising a tubular handle 118 having a first end inserted through the interior of the rod.
- the rod 110 is detachably secured to the first end of the handle 118 by being slipfit over the end of the handle.
- the interior diame ⁇ ter of the rod 110 is substantially equal to the exterior diameter of the handle 118 so that the rod 110 may be easily slipfit over the end of the handle 118 and held on the handle end by friction engagement.
- the rod has a slot 120 that is equal in length to the slot 116 of the rod and is aligned with the rod slot.
- the longitudinal length of the instru ⁇ ment handle 118 enables it to be used in both deep open incisions or in laparscopic surgery as in the previously described embodiments.
- the ability of the rod 110 to be detached from the handle 118 enables the rod to be de- tached and disposed of after use and replaced on the handle by a like rod.
- the handle slot 120 has a longitudinal length substantially equal to that of the rod slot 116 but is also provided in a specific configu ⁇ ration that enables the handle slot 120 to grip the nee- die 114 between the opposite lateral ends of the slot.
- the handle slot 120 having such an ability, it is no longer necessary to provide a magnetic strip along the slot of the rod 110 to temporarily hold the needle 114 while using the instrument of the invention.
- the opposite lateral ends 122, 124 of the handle slot 120 are curved underneath and then back toward the interior surface of the handle 118. This gives the handle slot 120 a much narrower width than the slot 116 of the rod 110 enabling it to pinch grip the needle 114 within the slot.
- the manner in which the opposite lateral ends 122, 124 of the handle slot 120 are bent down into the interior bore 126 of the handle 118 forms a pair of tapered converging surfaces in the under ⁇ side of the slot 120 that direct the needle 114 into the slot 120 when it is inserted into the handle bore 126 from the handle first end and then upward toward the slot.
- the tapered surfaces of the " underside of the slot 120 direct the tip of the needle 114 inserted into the handle bore 126 upward as viewed in Figure 12 into the slot 120 thereby facilitating positioning the needle 112 in its gripped stationary position in the slot.

- This embodiment of the rod 130 is substantially identical to the first described embodiment of Figures 1 and 4 except for the configuration of the rod slot 132.
- the first end of the rod 130 has the same cylindrical configuration of the first described embodiment of Fig ⁇ ures 1 and 4 and although not shown, a length of suture material is wrapped over the exterior surface of the rod and the slot 132 with one end of the suture secured to the rod and the opposite end of the suture secured a needle in the same manner as the first described embodi ⁇ ment.
- the embodiment of Figure 13 differs from the pre ⁇ viously described embodiment of Figures 1 and 4 in that the configuration of the slot 132 is substantially iden ⁇ tical to that of the just described embodiment of the instrument handle 118 shown in Figures 11 and 12.
- the instrument rod slot 132 is formed with its opposite lat ⁇ eral edges 134, 136 being downturned into the interior bore 138 of the rod to form the slot configuration shown in Figure 13.
- the configuration of the rod slot 132 operates in substantially the same manner as described above with regard to the handle slot 120 of Figures 11 and 12 to direct the needle inserted into the rod bore 138 upward into the slot and to pinch-grip the needle within the slot.
- With the configuration of the instru ⁇ ment rod 130 shown in Figure 13 it would not be necessary to provide a strip magnet adjacent the slot 132 as the function of temporarily holding the needle relative to the rod end is performed by the configuration of the slot itself.

Description
INSTRUMENT FOR TYJNG A KNOT IN SUTURES
Background of the Invention
(1) Field of the Invention
The present invention pertains to a surgical instrument for tying a knot in a length of suture at a remote location and the method of' using the instrument in tying the knot.
(2) Description of the Related Art
Various different types of instruments are known in the prior art for use in tying knots in lengths of suture material. Many of these prior art instruments have been developed with the intent to facilitate tying knots in suture material at surgical sites located in remote areas that are difficult to access. Many prior art instruments are designed for use in surgical proce¬ dures where large, deep incisions are made into the body. The instruments enable tying knots in sutures deep in the incisions. Many prior art instruments are also designed for use in laparoscopic surgical procedures where small incisions are made and the remote surgical site is ac¬ cessed through cannulas or tubes. Examples of known
instruments employed in tying knots in lengths of suture material are disclosed in the U.S. Patents of Larzelere No. 2,595,086, Mulhollan et al. No. 4,602,635, Hayhurst No. 4,961,741, the U.S. Patents of Li Nos. 5,084,058; 5,087,263; and 5,163,946; and the U.S. Patent of Li et al. No. 5,133,723.
A common characteristic of many known surgical knot-tying instruments is that they are very complicated to operate and time consuming to set up prior to their use. Moreover, many prior art surgical knot-tying in¬ struments are used in a procedure that involves first tying the knot in a length of suture remote from the surgical location and then moving the loose knot along the length of suture material to a position proximate to the surgical location before the knot is tightened at the surgical location. Summary of the Invention
The present invention overcomes disadvantages commonly associated with prior art surgical knot-tying instruments by providing a simplified surgical instrument for tying a knot in a length of suture proximate to a surgical site. More specifically, the surgical instru¬ ment of the present invention may be employed in either open incision or laparoscopic surgery procedures to posi- tion a needle and a length of suture material proximate to a surgical location and to form one or more stitches with the length of suture material at the surgical loca¬ tion, and then to tie a knot in the length of suture material at the surgical location where the knot is formed from two or more throws of the suture material.
The instrument is basically comprised of an elon¬ gate rod having opposite first and second ends. The longitudinal length of the rod is designed to enable the first end of the rod to be inserted through a convention- al, laparoscopic cannula to position the rod first end proximate to a surgical location or site within a body
cavity accessible by the cannula. The second end of the rod projects from the cannula where it is grasped manu¬ ally to enable manipulation of the rod first end within the body cavity. In alternate embodiments of the inven- tion, the rod has a shortened longitudinal length and is connected to an elongate handle that enables manipulation of the rod within the body cavity through a cannula by manual manipulation of the handle. In this embodiment of the invention, the rod is detachable from the handle for its removal and disposal after use and replacement by a like rod on the handle.
The first end of the rod is provided with an indentation or slot that extends into the interior of the rod from the rod's exterior surface. A length of suture material is provided on the rod first end. The length of suture has a needle secured to its first end and the second end of the suture is secured to the second end of the rod or to the handle. The length of suture is wrapped around the first end of the rod in a specific pattern that provides a plurality of loops of the suture material around the first end extending over the slot formed in the rod. A portion of the suture's length extends from the last of the plurality of suture loops formed on the rod first end to the needle at the first end of the suture.
Means are provided on the first end of the rod for releasably holding the needle to the rod first end. In the preferred embodiment, a magnet is encased in the material of the rod adjacent the rod first end. The magnet attracts the needle to the rod end and holds the needle in position on the rod end where it may be easily removed.
In use, the first end of the rod is positioned proximate to a surgical location by inserting the rod end into an open incision or by inserting the rod first end through the interior of a cannula providing access to a
body cavity. With the first end of the rod positioned proximate to the surgical location, the needle is removed from its magnetic attachment to the rod either manually or by gripping the needle with a laparoscopic grasper. One or more stitches are made in the desired positions at the surgical location and in preparation to form a first throw of a knot in the suture material, the needle is inserted into the slot in the rod first end beneath the first loop of suture material formed on the rod end. The needle is held in this position beneath the first loop of suture by the magnetism of the rod first end. The needle is released by the grasper and then retaken by the grasp¬ er at the distal end of the needle projecting from be¬ neath the first suture loop. The needle and the first end of the suture material are then pulled from the slot and from beneath the first suture loop causing the first loop to move off the first end of the rod. As the needle and first end of the suture are continued to be pulled away from the rod first end, the first loop moves down the length of suture toward the stitch made at the surgi¬ cal location, forming a first throw of a knot in the suture material securely closing the stitch. This proce¬ dure may be repeated as many times as there are suture loops formed on the rod first end to form a knot of any desired number of throws. When the desired knot is formed at the stitch in the surgical location the two lengths of suture extending from the knot are cut and the knot-tying instrument and needle are removed from the surgical location.

Description of the Preferred Embodiments
A first embodiment of the surgical instrument 12 of the present invention is shown in Figures 1 and 4. This first to be described embodiment of the invention, as well as other embodiments of the invention yet to be described, may be constructed of any materials acceptable
for use in surgical operations. The instrument is basi¬ cally comprised of an elongate rod 14, a length of suture material 16 secured to the rod, and a needle 18 secured to the length of suture material. The elongate rod has opposite first 20 and second 22 ends, or left hand and right hand ends respectively, adjacent opposite first 24 and second 26 end faces, or left and right end faces, as viewed in Figures 1 and 4. A hollow interior bore 28 extends longitudinally through the rod 14 between its end faces 24, 26. The interior and exterior diameter dimensions of the rod 14, as well as its longitudinal length between end faces, may vary depending on the intended application of the instrument. The instrument is designed for use with both open inci- sion surgery and laparoscopic surgery and the rod 14 of the instrument may be dimensioned so that it can be easi¬ ly inserted through the interior of a cannula in laparoscopic surgery applications. Additionally, the lateral dimensions of the instrument rod 14 may be enlarged to further facilitate its use in open incision surgical operations. The dimensions of the rod 14, su¬ ture material 16, and needle 18 shown in the drawing figures are not to scale and are not proportionate but are enlarged in Figures 1 and 4 to better illustrate the component parts of the invention and their relationship to each other. Moreover, it is not necessary that the instrument rod have the cylindrical configuration shown in Figures 1 and 4.
A slot 30 is formed through the exterior surface 32 of the rod adjacent its first end 20 forming a recess or indentation into the rod from the exterior surface to the interior bore 28. As seen in the drawing figures, the slot 30 extends longitudinally from the first end face 24 of the rod along a portion of the rod's length. A second smaller slot 34 or slit is formed in the second end 22 of the instrument rod extending along a portion of
the longitudinal length of the rod from the second end face 26.
The length of suture material 16 has opposite first 36 and second 38 ends with the first end 36 of suture material being secured to the needle 18 in a con¬ ventional manner. The total length of the suture materi¬ al between its first and second ends may vary depending on the intended application of the surgical instrument of the invention, as will be explained. The second end 38 of the suture is secured adjacent the rod second end 26 by inserting the suture into the narrow slot 34. In variant embodiments of the invention, the second end 38 of the suture may be secured to the instrument rod 14 in any equivalent manner, or may be manually held adjacent the rod second end in use of the surgical instrument. The length of suture 16 extends from the instrument rod second end 22 along the exterior surface of the rod to¬ ward the rod first end 20 and is wrapped in several loops 42, 44, 46, 48, 50, 52 at the first end 20 of the rod. From the last of the plurality of loops, the suture mate¬ rial extends to its first end 36 secured to the needle 18.
As best seen in Figure 1, each of the loops of suture material are wrapped around the exterior surface of the rod in a specific configuration that enables indi¬ vidual loops to be spaced from each other along the rod first end 20 and also enables individual loops to be manipulated to slide along the longitudinal length of the rod first end without causing adjacent loops to move along the length of the rod. Although a specific arrangement of the suture material to form the plurality of loops is shown in Figure 1, it should be appreciated that the suture material 16 may be formed in a variety of different loop configurations on the rod first end 20 that enable the plurality of suture loops to be spaced from each other as shown in Figure 1 and allow individual
loops of suture material to be manually moved longitudi¬ nally over the exterior surface of the rod without caus¬ ing adjacent loops to be moved.
The specific configuration of the suture loops shown in Figure 1 is produced by forming a first bend 54 in the suture material 16 as it extends longitudinally over the exterior surface of the rod 14 from the second end 22 toward the first end 20 of the rod. From the first bend 54, the suture material extends laterally relative to the rod and is wrapped one complete revolu¬ tion around the exterior surface of the rod back to the first bend 54. The suture material is then formed in a second bend 56 around the first bend 54 of the suture and again extends longitudinally along a portion of the rod's length, thereby completing the formation of the first loop 42 in the suture material. The subsequent or adja¬ cent loop 44 is formed in substantially the same manner as the first described loop 42. In forming the second loop, a first bend 58 is formed in the suture material and the suture extends from the first bend laterally around the exterior surface of the rod 14 one complete revolution back to the first bend of the second loop. Next, a second bend 60 is formed in the suture material around the first bend 58 of the second loop. The suture material continues to extend longitudinally toward the rod first end 20 from the second bend 60, thereby com¬ pleting the second loop 44 of suture material formed on the exterior of the rod 14. The remaining pairs of loops 46 and 48, 50 and 52, are formed in the suture material as it extends toward the rod first end 20 in the identi¬ cal manner as the first pair of loops 42, 44 just described.
To illustrate that the loops of suture material formed over the exterior surface of the rod 14 may be formed in a variety of different configurations without departing from the intended scope of the claims of the
invention, it is noted that the first and second loops 42, 44 are substantially mirror images of each other, and the second and third loops 44, 46 are also substantially mirror images of each other. In variations of the inven- tion, these first three loops of suture material may have been wound around the exterior surface of the rod 14 so that their configurations are substantially identical to each other, as are the first and third loops 42, 46. Moreover, all of the loops of suture material could have been wrapped around the exterior of the rod 14 in sub¬ stantially the same configuration as the first loop 42 or all of the plurality of loops could have been wrapped in substantially the same configuration as the second loop 44 without departing from the intended scope of the claimed invention and without altering the operation of the invention or its method of use.
To prevent the plurality of suture loops from unraveling from the rod first end 20 and to prevent the needle 18 from hanging free from the rod first end a strip magnet 64 is encased in the material of the rod first end extending along one side of the first slot 30 as shown in Figure 4. By positioning the needle 18 adja¬ cent the side of the slot 30 having the strip magnet 64, the needle is held securely in place at the rod first end 20 as shown in Figure 4. Alternate means of securing the needle 18 at the rod first end 20 may be employed in place of the strip magnet 64. For example, the rod first end 20 may be formed without the strip magnet 64 and the needle 18 may be positioned between the suture loop 52 formed adjacent the rod first end face 24 and the exteri¬ or surface 32 of the rod to securely hold the needle in place. To prevent the needle tip from projecting from the rod first end the needle may be given a curvature substantially equal to that of the rod exterior surface so that it may be positioned beneath the end loop 52 extending adjacent the rod exterior surface to its tip.
In variant embodiments of the instrument rod 14 the strip magnet 64 could be eliminated from its position adjacent the slot 30 and the needle 18 could be held in place relative to the rod by a conventional laparoscopic surgery grasper inserted through the rod interior bore 28 from its second end 22. The exterior diameter of the rod 14 would be dimensioned small enough to enable it to be inserted through the interior of a conventional laparoscopic cannula. The interior diameter of the rod bore 28 would be dimensioned sufficiently large to enable the insertion of a conventional laparoscopic grasper through the bore. The grasper would be inserted through the rod bore from the rod second end 22 with the jaws of the grasper positioned adjacent the rod first end 20. In this position of the grasper, the jaws would grip and releasably hold the needle 18 on insertion of the first end of the instrument rod through the cannula into the body cavity, and in subsequent manipulations of the nee¬ dle in forming throws of a knot according to the method of the invention yet to be described. Using the surgical instrument of the invention 12 in this manner also pro¬ vides the surgeon with a pair of laparoscopic graspers to use together with the instrument in forming stitches laparoscopically without the requirement of inserting more than a pair of cannulas into the body cavity.
In the illustrated embodiment of the invention shown in Figures 1 and 4, six suture loops are formed in a length of suture material, and the longitudinal length of the first slot 30 is extended along the length of the rod so that it passes beneath each of the loops formed in the suture material. In variant embodiments of the in¬ vention, the number of suture loops may vary and the longitudinal length of the slot beneath the loops may also vary. In use of the invention, it is only necessary that the longitudinal length of the slot be sufficient to
enable each of the plurality of loops formed in the su¬ ture material to extend over the slot.
Figure 2 shows a variant embodiment of the rod 70 of the surgical instrument. In this embodiment, the rod again has a cylindrical configuration; however, the rod does not have a hollow interior bore as in the first embodiment. The rod configuration shown in Figure 2 is solid with the slot 72 extending down into the interior of the material of the rod from the exterior surface 74. The slot 72, like the slot of the first embodiment, ex¬ tends for a portion of the longitudinal length of the rod from the rod first end face 76. The longitudinal length of the slot 72 is determined to enable the slot to extend beneath the plurality of loops formed in suture material (not shown) wrapped over the first end of the rod 70. The remaining component parts, i.e. the suture material and needle, of the second embodiment of the surgical instrument employing the solid rod 70 are substantially identical to those of the first described embodiment of Figures 1 and 4.
Figure 3 shows a still further variant embodiment of the surgical instrument rod 78. In the embodiment of the rod 78 shown in Figure 3, the first end, or left hand end of the rod as viewed in Figure 3, may have the same tubular configuration of the first described embodiment of Figures 1 and 4 or may have the solid configuration of the rod shown in Figure 2. The rod has a slot 80 formed in its first end in the same manner as the previously described embodiments and a length of suture material is wrapped over the exterior surface of the rod and the slot with one end of the suture secured to the rod and the opposite end of the suture secured to a needle 82 in the same manner as the first described embodiments. The embodiment of Figure 3 differs from the previously de- scribed embodiments in that the longitudinal length of the surgical instrument is divided into two sections with
the first section comprising the rod 78 and the second section comprising a handle 86. As shown in Figure 3, the second end of the rod 78 is detachably secured to one end of the handle 86 by a threaded connection 88. Other equivalent means of providing a releasable connection may also be employed. In this embodiment of the invention, the longitudinal length of the instrument enables it to be used in both deep open incisions or in laparoscopic surgery as in the previously described embodiments. The ability of the rod 78 to be detached from the handle 86 enables the rod to be detached and disposed of after use and replaced on the handle by a like rod. With the con¬ figuration of the surgical instrument shown in Figure 3, once the length of suture has been used from one rod of the instrument the used rod may be detached from the handle and replaced with a new rod having a length of suture looped over its exterior surface.
Figures 5-10 are schematic representations of the method of the invention employed in using the surgical instrument of the invention for tying a knot in a length of suture in a laparoscopic surgical operation. The drawing figures and their descriptions to follow only generally describe one use of the surgical instrument of the invention and are employed only to illustrate some benefits provided by the surgical instrument of the in¬ vention. Drawing Figures 5-10 and their descriptions to follow describe use of the surgical instrument of the invention in laparoscopic surgery forming a single stitch to close an incision. Again, it should be understood that the description to follow is illustrative only and should not be interpreted as limiting the use of the surgical instrument of the invention to only laparoscopic surgical techniques or only use in forming one stitch in securing adjacent tissues together. The benefits provid- ed by the unique surgical instrument of the present in¬ vention suit it for use in a variety of different known
surgical techniques and for use in forming both a single stitch and a line of stitching in body tissues.
Figure 5 is a schematic representation of a view looking inside a body cavity toward an opening in a tis- sue 90 representing a defect to be repaired or mended by use of the surgical instrument of the invention in accor¬ dance with the method of the invention. The drawing figure and Figures 6-10 to follow illustrate a laparoscopic repair of the defect 90 in the tissue and a pair of trocars 92, 94 are shown already inserted through left and right flanks of the body into the cavity, respectively. Graspers 96 are shown inserted through the left trocar 92 into the body cavity and the first end of the surgical instrument rod 98 with the length of suture 100 wrapped thereover and the needle 102 secured to the suture are shown inserted through the right trocar 94. The needle 102 is shown releasably held to the first end of the instrument rod 98 by a magnet encapsulated in the material of the rod, as was explained earlier. The length of suture extending from the needle 102 to the first suture loop 104 formed on the rod end may be longer than that shown in Figure 5 to facilitate manipulation of the needle in producing a stitch through the defective tissue 90. The excess length of suture between the nee- die 102 and the first suture loop 104 may be spirally wound on the rod first end between the rod end face 106 and the first loop 104. In preparing to use the instru¬ ment of the invention, the second end of the rod 98 (not shown) extending from the exterior end of the trocar 94 is manipulated to position the rod first end proximate to the surgical location or the defective tissue 90. The graspers 96 are then used to remove the needle 102 from its magnetic attachment to the rod end and a stitch is made through the tissue defect 90 at the surgical loca- tion. Only one stitch is shown being made in Figure 6; however, as explained earlier, the surgical instrument of
the invention may be employed in forming a line of stitching to close a larger tissue defect. In forming a line of stitching, the needle and attached length of suture are passed through the tissue defect several times along the line in one direction and then are passed again through the tissue defect along a return line back to the position where the suture was first inserted through the tissue. This positions the length of suture extending to the tissue defect from the instrument rod and the length of suture extending from the tissue defect to the needle adjacent each other. With these two lengths of suture positioned adjacent each other a knot may be formed in the suture in the same manner as after forming a single stitch in the tissue defect. In preparation to form a first throw of a knot in the suture material, the needle is repositioned by the grasper in the slot in the first rod end with the needle extending beneath the first loop 104 of suture material formed on the rod end. Figure 4 shows in more detail the proper positioning of the needle in preparing to form the first throw of the surgical knot. The needle is held in this position beneath the first loop of the suture by the magnetism of the first rod end. The needle is then re¬ leased by the grasper 96 and then retaken by the grasper at the distal end of the needle, or the point end of the needle projecting from beneath the first suture loop 104 and out of the slot as viewed in Figure 8. The needle and attached suture material are then pulled from the instrument slot and from beneath the first suture loop 104 causing the first loop to move off of the first end of the rod as shown in Figure 9. As the needle and first end of the suture are continued to be pulled away from the rod first end by the grasper, the first loop 104 moves down along the length of suture attached to the needle toward the stitch made at the surgical location in the tissue defect 90, forming a first throw of a knot in
the suture material securely closing the stitch, as shown in Figure 10.
The above process is repeated with the needle and attached suture passing through the slot and beneath the second loop 106 of suture formed on the exterior of the rod first end. As the needle and attached suture are pulled out of the slot and from beneath the second loop 106, the second loop is pulled off the rod first end down the length of suture attached to the needle. As the needle and attached suture are continued to be pulled away from the rod first end, the second loop arrives at the stitch formed by the first throw and forms a second throw of the knot at the stitch. If so desired, the procedure is repeated a third time by inserting the nee- die beneath the third loop 108 of suture and pulling the needle from beneath the loop and from the rod first end to cause the third loop to move off the rod end and down the suture forming a third throw in the knot at the stitch. This procedure may be repeated as many times as there are suture loops formed on the rod first end to form a knot of any desired number of throws. When the desired knot is formed at the stitch in the surgical location, the two lengths of suture extending from the knot are cut and the knot-tying instrument and needle are removed from the surgical location.
It should be appreciated that the surgical instru¬ ment of the invention facilitates tying a knot in a length of suture material at a remote surgical location according to the method of the invention by enabling the positioning of the suture material proximate to the sur¬ gical location and by holding the suture material at the surgical location in a manner that enables one or more throws of a knot to be easily formed in the suture mate¬ rial. Figure 11 shows a still further embodiment of the rod 110 of the surgical instrument similar to the embodi-
ment shown in Figure 3. In this embodiment, the rod has substantially the same configuration as the embodiment shown in Figures 1 and 4 with the length of suture mate¬ rial 112 and the needle 114 affixed thereto looped over the exterior surface of the rod 110 in substantially the same manner as that described with reference to Figures 1 and 4. The rod 110 has a slot 116 formed in its first end in the same manner as the previously described em¬ bodiment of Figures 1 and 4 and the length of suture material is looped over the slot. Like the Figure 3 em¬ bodiment, in the Figure 11 embodiment the longitudinal length of the surgical instrument is divided into two sections, with the first section comprising the rod 110 and the second section comprising a tubular handle 118 having a first end inserted through the interior of the rod. As shown in Figure 11, the rod 110 is detachably secured to the first end of the handle 118 by being slipfit over the end of the handle. The interior diame¬ ter of the rod 110 is substantially equal to the exterior diameter of the handle 118 so that the rod 110 may be easily slipfit over the end of the handle 118 and held on the handle end by friction engagement. The rod has a slot 120 that is equal in length to the slot 116 of the rod and is aligned with the rod slot. Like the embodi- ment of Figure 3, the longitudinal length of the instru¬ ment handle 118 enables it to be used in both deep open incisions or in laparscopic surgery as in the previously described embodiments. The ability of the rod 110 to be detached from the handle 118 enables the rod to be de- tached and disposed of after use and replaced on the handle by a like rod. With the configuration of the surgical instrument shown in Figures 11 and 12, once the length of suture has been used from one rod 110 of the instrument the used rod may be detached from the handle 118 and replaced with a new rod having a length of suture looped over its exterior surface.
As explained above, the handle slot 120 has a longitudinal length substantially equal to that of the rod slot 116 but is also provided in a specific configu¬ ration that enables the handle slot 120 to grip the nee- die 114 between the opposite lateral ends of the slot. With the handle slot 120 having such an ability, it is no longer necessary to provide a magnetic strip along the slot of the rod 110 to temporarily hold the needle 114 while using the instrument of the invention. As best seen in Figure 12, the opposite lateral ends 122, 124 of the handle slot 120 are curved underneath and then back toward the interior surface of the handle 118. This gives the handle slot 120 a much narrower width than the slot 116 of the rod 110 enabling it to pinch grip the needle 114 within the slot. The manner in which the opposite lateral ends 122, 124 of the handle slot 120 are bent down into the interior bore 126 of the handle 118 forms a pair of tapered converging surfaces in the under¬ side of the slot 120 that direct the needle 114 into the slot 120 when it is inserted into the handle bore 126 from the handle first end and then upward toward the slot. The tapered surfaces of the" underside of the slot 120 direct the tip of the needle 114 inserted into the handle bore 126 upward as viewed in Figure 12 into the slot 120 thereby facilitating positioning the needle 112 in its gripped stationary position in the slot.
A still further embodiment of the rod 130 of the surgical instrument of the invention is shown in Figure 13. This embodiment of the rod 130 is substantially identical to the first described embodiment of Figures 1 and 4 except for the configuration of the rod slot 132. The first end of the rod 130 has the same cylindrical configuration of the first described embodiment of Fig¬ ures 1 and 4 and although not shown, a length of suture material is wrapped over the exterior surface of the rod and the slot 132 with one end of the suture secured to
the rod and the opposite end of the suture secured a needle in the same manner as the first described embodi¬ ment. The embodiment of Figure 13 differs from the pre¬ viously described embodiment of Figures 1 and 4 in that the configuration of the slot 132 is substantially iden¬ tical to that of the just described embodiment of the instrument handle 118 shown in Figures 11 and 12. The instrument rod slot 132 is formed with its opposite lat¬ eral edges 134, 136 being downturned into the interior bore 138 of the rod to form the slot configuration shown in Figure 13. The configuration of the rod slot 132 operates in substantially the same manner as described above with regard to the handle slot 120 of Figures 11 and 12 to direct the needle inserted into the rod bore 138 upward into the slot and to pinch-grip the needle within the slot. With the configuration of the instru¬ ment rod 130 shown in Figure 13 it would not be necessary to provide a strip magnet adjacent the slot 132 as the function of temporarily holding the needle relative to the rod end is performed by the configuration of the slot itself.
While the present invention has been described by reference to a specific embodiment, it should be under¬ stood that modifications and variations of the invention may be constructed without departing from the scope of the invention defined in the following claims.
