- an endoscopic suturing device comprises an elongate flexible outer tubular endoscope member 20 formed with a biopsy channel 22 extending longi ⁇ tudinally through the tubular member.
- Biopsy channel 22 includes a first substantially cylindrical portion 24 and a second substantially cylindrical portion 26 each extending the length of tubular member 20 and communicating with one another throughout that length via a connecting channel portion 28.
- tubular member 20 is connected to con ⁇ ventional endoscope handling devices (not illustrated) .
- the endoscopic suturing device further comprises an elongate flexible inner tubular member 32 slidably disposed in biopsy channel portion 24.
- Inner tubular member 32 is pro ⁇ vided with a cylindrical bore 34 extending from a proximal end of the tubular member to a shoulder 36 formed near a distal end of member 32.
- bore 34 communicates with a thinner cylindrical bore 38 extending from shoulder 36 to the distal end of inner tubular member 32.
- the endoscopic suturing device also comprises a cylindrical rod member 40 which is slidably received inside bore 34 of inner tubular member 32.
- Rod member 40 is provided at a distal end with a cylindrical finger element 42 having a diameter which is less than the diameter of the main body of rod member 40 and less than the diameter of bore 38.
- the endoscopic suturing device additionally com ⁇ prises a needle 44 having a spring bias construction tending to bend needle into an arcuate configuration (see Fig. 2) .
- Needle 44 is made of prestessed nylon or polypropylene or a metal.
- Needle 44 is loaded into bore 38 of inner tubular mem ⁇ ber 32 so that the needle is disposed in a straightened con ⁇ figuration in bore 38 distally of a distal end of rod member 40 (see Fig. 3) .
- a suture 46 includes a thread member 48 attached at one end to a loop member 50 and attached at an opposite, free, end to a proximal end of needle 44 (see Figs. 2 and 3) .
- the endoscopic suturing device of Figs. 1-3 includes a a forceps device 52 for closing suture 46 upon an ejection of needle 44 from bore 38 (and hence from biopsy channel por ⁇ tion 24) by a distally directed motion of rod member 40 and upon a subsequent assumption by needle 44 of its prestressed arcuate configuration.
- Forceps device 52 includes a pair of actuator grips 54 and 56 at a proximal end, a pair of forceps jaws 58 at a distal end, and an elongate flexible body portion 60 slidably inserted through channel portion 26 of endoscope biopsy channel 22.
- Inner tubular member 32 and rod member 40 may be provided at a distal end with suitable handgrips (not illustrated) well known to the endoscope arts.
- suitable handgrips (not illustrated) well known to the endoscope arts.
- the materials of which inner tubular member 32 and rod member 40 are com ⁇ posed enable a sliding fit between those members.
- the diameters of inner tubular member 32, rod member 40, and biopsy channel portion 24 are selected in part to facili ⁇ tate a bending of the endoscope through pathways internal to a patient's body.
- needle 44 is inserted into the distal end of bore 38, while rod member 40 is inserted into the proximal end of bore 34 up to shoulder 36.
- Forceps 52 is then inserted through loop mem ⁇ ber 50 (see Fig. 3) and the assembly including inner tubular member 32, rod member 40, suture 46 and forceps device 52 is then inserted into biopsy channel 22 at the proximal end of outer tubular member 20.
- a suture 110 utilizable as suture 46 comprises a thread member 126, a loop member 124, a connector element or joint portion 114, and inwardly project ⁇ ing aperture-forming wings 117 and 118 on loop member 124.
- Suture device 110 further comprises a locking mechanism in the form of a pair of inwardly projecting resilient protuberances 111 and 113 on wings 117 and 118.
- Thread member 126 is formed along a portion of its length with a series of conically tapering projections 128 and has an outer diameter ODl defined by a maximum outer transverse dimension of projections 128. Projections 128 each taper from the maximum outer transverse dimension on a side facing joint portion 114 to a mimimum traverse dimension at the adjacent projection.
- Loop member 124 defines an opening 115 having an effective linear dimension or overall diameter OD2 (when the loop is circularly arranged) substantially larger than outer diameter ODl of thread member 126.
- Connector or joint portion
- loop member 114 serves to couple one end of thread member 126 to loop mem ⁇ ber 124.
- Loop member 124, inwardly projecting wings 117 and 118 and protuberances 111 and 113 define a generally oval aperture 116 having a linear dimension or size smaller than outer diameter ODl of thread member 126.
- aperture 116 has an area smaller than the cross-sectional area of projections 128 at the large ends thereof.
- Linear dimension or overall diameter 0D2 of loop member opening 115 is preferably at least twice as large as outer diameter ODl of thread member 126.
- open ⁇ ing 115 of loop member 124 has an area at least four times the cross-sectional area subtended by projections 128 at their largest width or diameter. This substantial difference in the dimensions of opening 115 and thread member 126 enables prac ⁇ tical use of the suture. If opening 115 were smaller, forceps device 52 could would not be able to traverse opening 115.
- suture device 110 has a narrow range of operative sizes. This limitation arises from the fact that loop 124 remains an integral part of the suture after surgery has been completed. For example, if suture device 110 is used to close a tubular body organ such as a blood vessel or bile duct, the circumference of loop member 124 cannot exceed twice the cir- cumference of the vessel or duct.
- Protuberances 111 and 113 define a passageway or access channel 120 between opening 115 and aperture 116.
- the protuberances serve to prevent a removal of thread member 126 from aperture 116 upon a passing of thread member 126 through opening 115 (i.e., through loop member 124) and a subsequent pulling of thread member 126 into aperture 116 from opening 115 through access channel 120.
- Suture device 210 utilizable as suture 46 in the endoscopic suturing device of Figs. 1-3 is essentially identical to suture device 210.
- Suture device 210 comprises a thread member 226, a loop member 224, a connector element or joint portion 214, and inwardly projecting aperture-forming wings 217 and 218 on loop member 224.
- a pair of inwardly projecting resilient protuberances 211 and 213 are formed on wings 217 and 218 and serve in part to define an aperture 216 at an end of loop memer 224 opposite thread member 226.
- Thread member 226 is formed along a por ⁇ tion of its length with a series of conically tapering projec ⁇ tions 228 and has an outer diameter ODl' defined by a maximum outer transverse dimension of projections 228. Projections 228 each taper from the maximum outer transverse dimension on a side facing joint portion 214 to a mimimum traverse dimen ⁇ sion at the adjacent projection.
- Loop member 224 defines an opening 215 having an effective linear dimension or overall diameter OD2' (when the loop is circularly arranged) substantially larger than outer diameter ODl' of thread member 226.
- aperture 216 has a linear dimension or size smaller than outer diameter ODl' of thread member 226.
- aperture 216 has an area smaller than the cross-sectional area of projections 228 at the large ends thereof.
- Projections 228 are thin walled and generally col ⁇ lapse to a closed configuration shown at 229 in Fig. 5. In that closed configuration, projections 228 form a smooth sur ⁇ face when rubbed from the free end of thread member 226 towards loop member 224. Projections 228 expand into a lock ⁇ ing, opened configuration shown at 231 upon the application of a force directed along thread member 226 from loop member 224 towards the free end of the thread member.
- Suture devices 110 and 210 are integrally molded pursuant to techniques well known in the art.
- the sutures are made of polyethylene, polypropylene, nylon, tetrafluoroethylene or other synthetic resin or polymeric material which is essentially inert and therefore biochemi ⁇ cally safe for sustained contact with the body tissues of human beings and other animals.
- Needle 44 is similarly made of a biologically inert material. Needle 44 is attached to the free ends of thread members 126 and 226 by embedding tech ⁇ niques also well known in the art.
- loop members 124 and 224 are made of a flexible, thin, thread-like element.
- the thin thread-like element enables loop members 124 and 224 to be wound about a body tissue such as a blood vessel or duct.
- a body tissue such as a blood vessel or duct.
- the flexibility of the loop members enables suture 110 or 210 to conform to the body tissues to which it is attached.
- a distal end of the endoscopic suturing device of Figs. 1-3 upon an insertion of a distal end of the endoscopic suturing device of Figs. 1-3 into a patient's body (not shown) , light 62 is emitted from the dis ⁇ tal end of outer tubular member 20 and illuminates tissues 64 at an internal surgical site including a wound 66.
- Light 68 is reflected from the tissues 64 and is directed through an optical fiber or group of fibers 70 to an eyepiece (not shown) or camera (not illustrated) from whence a video picture is produced on a display screen (not depicted) .
- a surgeon visually inspects the surgical site through the medium of the transmitted optical radiation and determines the location of wound 66.
- the operating surgeon manipulates the endoscope to position the distal end of outer tubular member 20 optimally with respect to the surgical site.
- inner tubular member 32 Upon the proper positioning of the distal end of outer tubular member 20, inner tubular member 32, together with entrained rod member 40 and suture 46, is shifted longi ⁇ tudinally through biopsy channel portion 24 in the distal direction until a distal tip of the inner tubular member is juxtaposed to tissues 64, as shown in Fig. 6B.
- rod member 40 is shifted distally relative to counselnner tubular member 32 so that finger element 42 enters bore 38 and ejects needle 44 therefrom.
- needle 44 Upon ejection of needle 44, it assumes its prestressed arcuate configuration, as shown in Fig. 6C. The needle thus pierces internal body tissues 64 on both sides of wound 66.
- the operating surgeon slides inner tubular member 32, with entrained rod member 40, back into a withdrawn position (see Fig. 6D) and translates forceps device 52 distally so that forceps jaws 58 are justaposed to the protruding front end of needle 44.
- the surgeon then actuates grips 54 and 56 to open jaws 58 (Fig. 6E) .
- the entire endoscopic suturing device or, alternatively, forceps device 52 may subsequently be shifted further in the distal direction, if necessary, so that the protruding tip of needle 44 is disposed between the separated jaw members 58 (Fig. 6E) .
- the operating surgeon actuates grips 54 and 56 to close forceps jaws 58 upon visually detecting through the optical assembly of the endo ⁇ scope that the protruding free end of needle 44 is located between the jaws.
- the surgeon pulls forceps device 52 in the proximal direction.
- thread member 48 is pulled in the proximal direction, thereby moving loop mem ⁇ ber 50 in the distal direction.
- a cutting device such as a laser transmitting fiber 72 (Fig. 6H) through another biopsy channel 74 (Figs. 1 and 2) in outer tubular member 20 and manipulates the laser fiber so that a distal, output, end thereof is justaposed to thread member 48 at loop member 50.
- a laser source 76 is subsequently energized or activated to transmit a beam of radiation through fiber 72 to sever thread member 48.
- Fig. 7 shows the suture 210 of Fig. 5 in place in tissues 64 and binding wound 66 upon a severing of thread mem ⁇ ber 226 by a laser beam transmitted from laser source 76 via fiber 72 (Fig. 6H) or by another alternatively utilizable cut- ting instrument such as an endoscopic scalpel or scissors device.
- a portion of thread member 226 traverses aperture 216 and is locked into position by the cooperation of protuberances 211 and 213 and an expanded projection 228, the other projections along thread member 226 remaining in a col ⁇ lapsed or closed configuration.
- An endoscopic suturing device in accordance with the principles of the invention may include a pair of forceps devices insertable through biopsy channel portions 24 and 26.
- Such an endoscopic suturing device is particularly adapted to ligating tubular body organs such as blood vessels, bile ducts and Fallopian tubes.
- Such a device uses a suture device as described herein, with the loop member of the suture device being traversed by one of the forceps devices.

ENDOSCOPIC SUTURING DEVICE
AND RELATED METHOD AND SUTURE
Background of the Invention
This invention relates to an endoscopic suturing device. More particularly, this invention relates to a device usable with an endoscope for performing a sewing or stitching operation on a patient's internal body tissues at a surgical site not visible to the unaided eye. This invention also involves a surgical procedure utilizing an endoscope. The invention further relates to a surgical suture and an associ¬ ated needle both particularly adapted for use in a surgical procedure and an endoscopic stapling device in accordance with the invention.
Conventional surgical techniques for repairing tis¬ sue injuries such as hernias and perforated ulcers, for clos¬ ing other openings in internal body tissues and for ligating tubular body organs such as sperm ducts and Fallopian tubes, generally require that an extensive incision be made in the patient's abdominal wall. Such an operation is generally traumatic to the patient, involves considerable surgeon time and requires a relatively lengthy convalescence. This is the case even though only one or a small number of sutures is required to repair the injury or tie off the vessel. Objects of the Invention
An object of the present invention is to provide a surgical procedure for closing openings internal to a patient's body, which is less invasive than conventional surgical closure methods.
Another object of the present invention is to pro¬ vide such a surgical procedure which is quicker than conven¬ tional surgical proceures and which reduces the typical postoperative convalescence period.
A related object of the present invention is to pro¬ vide an improved surgical closure procedure using an endoscope or laparoscope.
Another object of the present invention is to pro¬ vide a suturing device usable with an endoscope or laparo¬ scope.
An associated object of the present invention is to provide an endoscopic-type suturing device.
Another, more particular, object of the present
invention is to provide a suture usable with such an endoscopic-type suturing device.
A further particular object of the present invention is to provide a surgical needle usuable with such an endoscopic-type suturing device. Summary of the Invention
A surgical instrument comprises, in accordance with the present invention, an endoscope or laparoscope and a needle having a spring bias construction tending to bend the needle into an arcuate configuration. The endoscopic instru¬ ment includes an elongate outer tubular member and a biopsy channel extending longitudinally through the tubular member, while the needle is disposed in a straightened configuration at least partially inside the biopsy channel at a distal end thereof. The surgical instrument further comprises an ejector device for ejecting the needle from the biopsy channel and a suture having an end attached to a proximal end of the needle. A closure device is provided for closing the suture upon an ejection of the needle from the biopsy channel by a distally directed motion of the rod member and a subsequent assumption by the needle of the arcuate configuration.
In a preferred embodiment of the invention, the ejection device includes an elongate rod member slidably dis¬ posed inside an elongate inner tubular member in turn slidably disposed in the biopsy channel of the endoscope's outer tubular member. The needle is then disposed in a straightened configuration at least partially inside the inner tubular mem¬ ber distally of a distal end of the rod member.
Pursuant to another feature of the present inven¬ tion, the closure device includes an elongate forceps member slidably disposed in the endoscopic instrument.
In accordance with another feature of the present invention, the biopsy channel of the endoscope or laparoscope includes a pair of parallel elongate main channel portions communicating with one another along their lengths via an elongate connecting channel portion. The inner tubular member is slidably disposed in one of the main channel portions, while the rod member is slidably disposed inside the other main channel portion.
Pursuant to another feature of the present inven¬ tion, the suturing needle is provided with a guide structure for controlling orientation of the needle prior to and during ejection of the needle from the biopsy channel by the ejector. The guide structure may include an irregular cross-section of the needle. That irregular, cross-section may extend throughout only a portion of the length of the needle, or, alternatively along the length of the entire needle.
The suture includes a loop member traversed by the elongate forceps member, the suture further including a thread member attached at one end to the needle and at an opposite end to the loop member. The thread member traverses the con¬ necting channel portion of the biopsy channel.
Pursuant to another feature of the present inven¬ tion, a locking device is provided for locking the suture upon closure thereof by the closure device. The locking device is essentially incorporated into the suture device and advantageously includes a series of projections provided along the thread member of the suture device and an aperture in the suture communicating with an opening defined by the loop mem¬ ber of the suture. Moreover, the thread member has an outer diameter defined by the projections, and the loop member's opening has a linear dimension substantially larger than the outer diameter of the thread member. The aperture has a linear dimension smaller than the outer diameter of the thread member, while the locking device further includes a part on the suture for preventing a removal of the thread member from the aperture upon a passing of the thread member through the loop member and a subsequent pulling of the thread member into the aperture from the loop member.
A severing device may be incoporated into the surgi¬ cal instrument for cutting or evering a portion of the suture upon a closing thereof. The severing device may include a laser device with an optical fiber insertable through a longi¬ tudinal opening in said outer tubular member.
Pursuant to specific feature of the present inven¬ tion, the rod member, the inner tubular member, the forceps member, and the main channel portions are all substantially cylindrical.
Pursuant to yet another specific feature of the present invention, an arrest is provided for preventing the rod member from moving more than a pretermined distance in a distal direction relative to the inner tubular member. In particular, the arrest includes a shoulder on the rod member engageable with a shoulder internal to the inner tubular mem¬ ber.
In accordance with a feature of the present inven¬ tion, a surgical assembly comprises an elongate tubular mem¬ ber, an elongate rod member, a needle having a spring bias construction tending to bend the needle into an arcuate con¬ figuration, and a suture. The tubular member has a diameter sufficiently small so that the tubular member is slidably insertable into a biopsy channel extending longitudinally through a tubular endoscopic member. The rod member is slidably disposed inside the elongate tubular member, while the needle is disposed in a straightened configuration at least partially inside the tubular member distally of a distal end of the rod member. The suture has an end attached to a proximal end of the needle. In addition, the assembly may include an elongate forceps member for closing the suture upon an ejection of the needle from the tubular member by a dis¬ tally directed motion of the rod member and a subsequent assumption by the needle of the arcuate configuration. In that event, the suture includes a loop member traversed by the elongate forceps member and further includes a thread member attached at one end to the needle and at an opposite end to the loop member.
A suture device in accordance with the present invention comprises a thread member, a loop member, a joint connecting the thread member to the loop member, a locking device or member, and a needle. The thread member is provided along at least a portion of its length with a series of resiliently collapsible projections, the thread member having an outer diameter defined by the projections. The loop member defines an opening having a linear dimension substantially larger than the outer diameter of the thread member. And either the joint or the loop member or both define at least in part an aperture having a linear dimension smaller than the
outer diameter of the thread member and communicating with the opening defined by the loop. The locking device serves to prevent a removal of the thread member from the aperture upon a passing of the thread member through the loop member and a subsequent pulling of the thread member into the aperture from the loop member. The needle has a sharp end and is attached at an opposite end to a free end of the thread member. In addition, the needle has a spring bias construction tending to bend the needle into an arcuate configuration.
Preferably, the projections along the thread member are collapsible under force applied along the thread member in one direction and expandable under force applied along the thread member in an opposite direction. More preferably, the projections take the form of substantially hollow conical ele¬ ments.
A method for performing a surgical operation on internal body tissues of a patient comprises, in accordance with the present invention, the steps of inserting a tubular endoscopic member through an aperture in the patient's body, using the endoscope or laparoscope to visually locate the internal body tissues inside the patient's body, and upon locating the surgical site, pushing an elongate rod member in a distal direction through a biopsy channel in the tubular endoscopic member to eject a needle disposed in a straightened configuration inside the channel at a distal end of the tubular endoscopic member; In this method, the needle has a spring bias construction tending to automatically bend the needle into an arcuate configuration, and the needle further has a proximal end attached to a suture. Upon ejection of the needle from the biopsy channel, the needle is passed in the arcuate configuration through the internal body tissues. After passing of the needle through the internal body tissues, the suture is closed, whereupon the tubular endoscopic member is withdrawn or removed from the patient's body though the introduction aperture.
Pursuant to another feature of the present inven¬ tion, the needle has a sharp end opposite its proximal end and the suture has a thread member and a loop member attached to the thread member at an end thereof opposite the needle. In
accordance with this feature of the invention, the step of closing the suture comprises the steps of grasping the sharp end of the needle and pulling the needle and a portion of the thread member through the loop member. Preferably, the grasp¬ ing of the sharp end of the surgical needle is accomplished with the aid of a forceps device, while pulling the needle and the thread member of the suture comprises the step of pulling a portion of the forceps device through the loop member of the suture. In another step, the suture is locked in a closed configuration upon a completedpulling of the thread member through the loop member of the suture.
In accordance with the present invention, the aper¬ ture through which the endoscope is introduced into the patient may be a natural body opening or, alternatively, may be formed by piercing the patient's body, e.g., with a trocar. In the lattter case, the instrument takes the form of a lapra- scopic or laparo-endoscopic instrument.
An endoscopic-type suturing device in accordance with the present invention enables a non-invasive closure of internal openings and vessels. Accordingly, an internal closure operation performed in accordance with the present invention will greatly reduce the physical and emotional trauma that many patients undergo during surgery design to close internal wounds or ligate tubular body organs.
More specifically, using a procedure in accordance with the present invention, many surgical operations can be accomplished without the formation of any new opening in the external body tissues. In such cases, the endoscopic suturing device is operated through a natural body aperture (the mouth or rectum) . In other cases, the only opening which is needed is one just large enough to accomodate a fiber optic endo¬ scope. Such an operation would be useful, for example, to repair hernias.
Use of an endoscopic suturing device in accordance with the present invention, therefore, minimizes operation time, as well as the hospital stay. Many patients can be therapeutically treated on an out-patient basis, thereby con¬ serving valuable room space and other hospital facilites for patients whose injuries or illness absolutely requires
invasive surgery.
A surgical instrument and technique in accordance with the present invention will serve to reduce hospitaliza- tion costs, as well as reduce complications attendant upon invasive surgical operations. Brief Description of the Drawing

As illustrated in Figs. 1-3, an endoscopic suturing device comprises an elongate flexible outer tubular endoscope member 20 formed with a biopsy channel 22 extending longi¬ tudinally through the tubular member. Biopsy channel 22 includes a first substantially cylindrical portion 24 and a second substantially cylindrical portion 26 each extending the length of tubular member 20 and communicating with one another throughout that length via a connecting channel portion 28. At a proximal end 30, tubular member 20 is connected to con¬ ventional endoscope handling devices (not illustrated) .
The endoscopic suturing device further comprises an elongate flexible inner tubular member 32 slidably disposed in biopsy channel portion 24. Inner tubular member 32 is pro¬ vided with a cylindrical bore 34 extending from a proximal end of the tubular member to a shoulder 36 formed near a distal end of member 32. On a distal side of shoulder 36, bore 34 communicates with a thinner cylindrical bore 38 extending from shoulder 36 to the distal end of inner tubular member 32.
The endoscopic suturing device also comprises a cylindrical rod member 40 which is slidably received inside bore 34 of inner tubular member 32. Rod member 40 is provided at a distal end with a cylindrical finger element 42 having a diameter which is less than the diameter of the main body of rod member 40 and less than the diameter of bore 38.
The endoscopic suturing device additionally com¬ prises a needle 44 having a spring bias construction tending to bend needle into an arcuate configuration (see Fig. 2) . Needle 44 is made of prestessed nylon or polypropylene or a metal. Needle 44 is loaded into bore 38 of inner tubular mem¬ ber 32 so that the needle is disposed in a straightened con¬ figuration in bore 38 distally of a distal end of rod member 40 (see Fig. 3) . A suture 46 includes a thread member 48 attached at one end to a loop member 50 and attached at an opposite, free, end to a proximal end of needle 44 (see Figs. 2 and 3) .
The endoscopic suturing device of Figs. 1-3 includes a a forceps device 52 for closing suture 46 upon an ejection of needle 44 from bore 38 (and hence from biopsy channel por¬ tion 24) by a distally directed motion of rod member 40 and upon a subsequent assumption by needle 44 of its prestressed arcuate configuration. Forceps device 52 includes a pair of actuator grips 54 and 56 at a proximal end, a pair of forceps jaws 58 at a distal end, and an elongate flexible body portion 60 slidably inserted through channel portion 26 of endoscope biopsy channel 22.
Inner tubular member 32 and rod member 40 may be provided at a distal end with suitable handgrips (not illustrated) well known to the endoscope arts. The materials of which inner tubular member 32 and rod member 40 are com¬ posed enable a sliding fit between those members. In addi¬ tion, the diameters of inner tubular member 32, rod member 40, and biopsy channel portion 24 are selected in part to facili¬ tate a bending of the endoscope through pathways internal to a patient's body.
To load the endoscopic suturing device of Figs. 1-3, needle 44 is inserted into the distal end of bore 38, while rod member 40 is inserted into the proximal end of bore 34 up to shoulder 36. Forceps 52 is then inserted through loop mem¬ ber 50 (see Fig. 3) and the assembly including inner tubular member 32, rod member 40, suture 46 and forceps device 52 is then inserted into biopsy channel 22 at the proximal end of outer tubular member 20.
As illustrated in Fig. 4, a suture 110 utilizable as
suture 46 comprises a thread member 126, a loop member 124, a connector element or joint portion 114, and inwardly project¬ ing aperture-forming wings 117 and 118 on loop member 124. Suture device 110 further comprises a locking mechanism in the form of a pair of inwardly projecting resilient protuberances 111 and 113 on wings 117 and 118. Thread member 126 is formed along a portion of its length with a series of conically tapering projections 128 and has an outer diameter ODl defined by a maximum outer transverse dimension of projections 128. Projections 128 each taper from the maximum outer transverse dimension on a side facing joint portion 114 to a mimimum traverse dimension at the adjacent projection.
Loop member 124 defines an opening 115 having an effective linear dimension or overall diameter OD2 (when the loop is circularly arranged) substantially larger than outer diameter ODl of thread member 126. Connector or joint portion
114 serves to couple one end of thread member 126 to loop mem¬ ber 124. Loop member 124, inwardly projecting wings 117 and 118 and protuberances 111 and 113 define a generally oval aperture 116 having a linear dimension or size smaller than outer diameter ODl of thread member 126. Generally, aperture 116 has an area smaller than the cross-sectional area of projections 128 at the large ends thereof.
Linear dimension or overall diameter 0D2 of loop member opening 115 is preferably at least twice as large as outer diameter ODl of thread member 126. Concomitantly, open¬ ing 115 of loop member 124 has an area at least four times the cross-sectional area subtended by projections 128 at their largest width or diameter. This substantial difference in the dimensions of opening 115 and thread member 126 enables prac¬ tical use of the suture. If opening 115 were smaller, forceps device 52 could would not be able to traverse opening 115.
It is to be noted, however, that loop member opening
115 of suture device 110 has a narrow range of operative sizes. This limitation arises from the fact that loop 124 remains an integral part of the suture after surgery has been completed. For example, if suture device 110 is used to close a tubular body organ such as a blood vessel or bile duct, the circumference of loop member 124 cannot exceed twice the cir-
cumference of the vessel or duct.
Protuberances 111 and 113 define a passageway or access channel 120 between opening 115 and aperture 116. The protuberances serve to prevent a removal of thread member 126 from aperture 116 upon a passing of thread member 126 through opening 115 (i.e., through loop member 124) and a subsequent pulling of thread member 126 into aperture 116 from opening 115 through access channel 120.
As shown in Fig. 5, another suture device 210 utilizable as suture 46 in the endoscopic suturing device of Figs. 1-3 is essentially identical to suture device 210. Suture device 210 comprises a thread member 226, a loop member 224, a connector element or joint portion 214, and inwardly projecting aperture-forming wings 217 and 218 on loop member 224. A pair of inwardly projecting resilient protuberances 211 and 213 are formed on wings 217 and 218 and serve in part to define an aperture 216 at an end of loop memer 224 opposite thread member 226. Thread member 226 is formed along a por¬ tion of its length with a series of conically tapering projec¬ tions 228 and has an outer diameter ODl' defined by a maximum outer transverse dimension of projections 228. Projections 228 each taper from the maximum outer transverse dimension on a side facing joint portion 214 to a mimimum traverse dimen¬ sion at the adjacent projection.
Loop member 224 defines an opening 215 having an effective linear dimension or overall diameter OD2' (when the loop is circularly arranged) substantially larger than outer diameter ODl' of thread member 226. In contrast, aperture 216 has a linear dimension or size smaller than outer diameter ODl' of thread member 226. Generally, aperture 216 has an area smaller than the cross-sectional area of projections 228 at the large ends thereof.
Projections 228 are thin walled and generally col¬ lapse to a closed configuration shown at 229 in Fig. 5. In that closed configuration, projections 228 form a smooth sur¬ face when rubbed from the free end of thread member 226 towards loop member 224. Projections 228 expand into a lock¬ ing, opened configuration shown at 231 upon the application of a force directed along thread member 226 from loop member 224
towards the free end of the thread member.
Suture devices 110 and 210 are integrally molded pursuant to techniques well known in the art. The sutures are made of polyethylene, polypropylene, nylon, tetrafluoroethylene or other synthetic resin or polymeric material which is essentially inert and therefore biochemi¬ cally safe for sustained contact with the body tissues of human beings and other animals. Needle 44 is similarly made of a biologically inert material. Needle 44 is attached to the free ends of thread members 126 and 226 by embedding tech¬ niques also well known in the art.
It is to be noted that loop members 124 and 224 are made of a flexible, thin, thread-like element. The thin thread-like element enables loop members 124 and 224 to be wound about a body tissue such as a blood vessel or duct. Thus, the flexibility of the loop members enables suture 110 or 210 to conform to the body tissues to which it is attached.
As shown in Fig. 6A, upon an insertion of a distal end of the endoscopic suturing device of Figs. 1-3 into a patient's body (not shown) , light 62 is emitted from the dis¬ tal end of outer tubular member 20 and illuminates tissues 64 at an internal surgical site including a wound 66. Light 68 is reflected from the tissues 64 and is directed through an optical fiber or group of fibers 70 to an eyepiece (not shown) or camera (not illustrated) from whence a video picture is produced on a display screen (not depicted) . A surgeon visually inspects the surgical site through the medium of the transmitted optical radiation and determines the location of wound 66. The operating surgeon manipulates the endoscope to position the distal end of outer tubular member 20 optimally with respect to the surgical site.
Upon the proper positioning of the distal end of outer tubular member 20, inner tubular member 32, together with entrained rod member 40 and suture 46, is shifted longi¬ tudinally through biopsy channel portion 24 in the distal direction until a distal tip of the inner tubular member is juxtaposed to tissues 64, as shown in Fig. 6B. In a subse¬ quent step of an operating procedure in accordance with the invention, illustrated in Fig. 6C, rod member 40 is shifted
distally relative to „nner tubular member 32 so that finger element 42 enters bore 38 and ejects needle 44 therefrom. Upon ejection of needle 44, it assumes its prestressed arcuate configuration, as shown in Fig. 6C. The needle thus pierces internal body tissues 64 on both sides of wound 66.
Upon a piercing of tissues 64 by needle 44, the operating surgeon slides inner tubular member 32, with entrained rod member 40, back into a withdrawn position (see Fig. 6D) and translates forceps device 52 distally so that forceps jaws 58 are justaposed to the protruding front end of needle 44. The surgeon then actuates grips 54 and 56 to open jaws 58 (Fig. 6E) . The entire endoscopic suturing device or, alternatively, forceps device 52 may subsequently be shifted further in the distal direction, if necessary, so that the protruding tip of needle 44 is disposed between the separated jaw members 58 (Fig. 6E) .
As depicted in Fig. 6F, the operating surgeon actuates grips 54 and 56 to close forceps jaws 58 upon visually detecting through the optical assembly of the endo¬ scope that the protruding free end of needle 44 is located between the jaws. Upon a gripping of needle 44 by jaws 58, the surgeon pulls forceps device 52 in the proximal direction. During this pulling step (Figs. 6F and 6G) , thread member 48 is pulled in the proximal direction, thereby moving loop mem¬ ber 50 in the distal direction.
Upon a pulling of thread member 48 through the aper¬ ture (116 or 216) of suture 46 and a locking of the suture device via the projections (128 or 228) on the thread member, the operating surgeon inserts a cutting device such as a laser transmitting fiber 72 (Fig. 6H) through another biopsy channel 74 (Figs. 1 and 2) in outer tubular member 20 and manipulates the laser fiber so that a distal, output, end thereof is justaposed to thread member 48 at loop member 50. A laser source 76 is subsequently energized or activated to transmit a beam of radiation through fiber 72 to sever thread member 48.
Fig. 7 shows the suture 210 of Fig. 5 in place in tissues 64 and binding wound 66 upon a severing of thread mem¬ ber 226 by a laser beam transmitted from laser source 76 via fiber 72 (Fig. 6H) or by another alternatively utilizable cut-
ting instrument such as an endoscopic scalpel or scissors device. A portion of thread member 226 traverses aperture 216 and is locked into position by the cooperation of protuberances 211 and 213 and an expanded projection 228, the other projections along thread member 226 remaining in a col¬ lapsed or closed configuration.
An endoscopic suturing device in accordance with the principles of the invention may include a pair of forceps devices insertable through biopsy channel portions 24 and 26. Such an endoscopic suturing device is particularly adapted to ligating tubular body organs such as blood vessels, bile ducts and Fallopian tubes. Such a device uses a suture device as described herein, with the loop member of the suture device being traversed by one of the forceps devices.
Bore 38 (see Figs. 2 and 3) may be provided at a distal end with a pair of diametrically opposed longitudinally extending grooves (not illustrated) for receiving portions of needle 44 and guiding the needle during an ejection step. The grooves or other orientation device thus serves to control the disposition of needle 44 in tissues 64 or about a tubular internal body organ during a suturing or ligating operation.
As illustrated in Figs. 8 and 9, an inner tubular member 432 of an endoscopic or laparoscopic surturing device is provided along an inner surface and at a distal end with a longitudinally extending groove 434. Groove 434 receives a guide fin 436 extending in a radial direction from a suturing needle 438 disposed in a prefiring, straigthened configuration inside inner tubular member 432. Guide fin 436 cooperates with groove 434 to control the orientation of needle 438 so that the needle bends or arches in a controlled direction upon ejection from the distal end of the instrument.
Figs. 10A and 10B depict another suturing needle 440 utilizable in an endoscopic or laparoscopic suturing device. Needle 440 has a cylindrical surface 442 on one side and a pair of planar surface 444 and 446 on an opposite side. As illustrated in Fig. 10A, needle 440 accordingly has an irregular cross-section which permits it to be keyed to a cor¬ respondingly shaped bore at the distal end of an inner tubular member. This keying serves to control the orientation of
needle 440 so that the needle bends or arches in a controlled direction upon ejection from the distal end of the instrument.
Figs. 11A, 11B and 12A, 12B and 13A, 13B show three more suturing needles each having an irregular cross-section which enables control of needle orientation prior to and dur¬ ing ejection of the needle from the distal end of an endoscopic-type suturing device as described hereinabove.
