2. Discussicn Of The Prior ~1~
A surgeon, when performing an operation on a patient, is often obstructed in his efforts to excise diseased or damaged tissues or organs by surrounding tissues~ fatty deposits, arteries, or other organs. It has generally been the case, when performing gastro intestinal surgery, i.e. surgery within the abdominal cavity, to make a large cut in the abdomen wall to produce a suitable opening to: ~ ~ allow access to the interior organs. This cut was generally large enough to allow the use of human hands, either those of the surgeons or those of a member of the surgical team, as a retractor. Surgical personnel would thus insert their hands through the incision into the abdominal cavity to push and hold organs and other obstructing components away from the surgical objective.

~ ecently, at least in part as a result of the evolution in electronic video technology, a surgical procedure known as laparoscopic surgery has undergone a marlced increase in popularity. The laparoscope consists of a long thin rigid tube, and 5 residing at one end of the tube is a viewing lens, while at the opposite end is a camera hook up and an eye piece. A small incision in the area of the surgical objective is made and the laparoscope is partially inserted into this incision, viewing lens first. High definition video cameras and monitors are then attached to the 10 camera hook up connector on the part of the laparoscope which remains positioned exteriorly of the body. In this manner, a surgical team can get a clear picture of the affected internal area without resorting to radical, disfiguring surgical incisions to physically open the patient. Other small incisions may then be made through the surface of the skin in the vicinity of the surgical objective. Through these incisions, 15 miniaturized surgical instruments such as scissors, forceps, clamps and scalpels may be inserted to perform various surgical procedures. The entire interiorly performed surgical procedure is monitored from the exterior through the high definition television monitor. In this manner radical incisions and scarring are avoided while 20 undertakin:g surgical repair or removal of damaged or diseased organs. Another benefit of laparoscopic surgery is the significantly reduced recovery time, whencompared to standard surgical procedures, due to the minuscule size of the scalpel incisions and avoiclance of the massive internal traumatization known in standard 25 surgical procedures. Accompanying the reduced recovery time are, of course, greatly reduced costs.
Therefore, there is a need to provide a clevice which may be partially inserted through a tiny surgical incision in the abdominal wall, which n-lay be used during laparoscopic surgery within the abdominal cavity, and which is useful to y~
manipulate an endoscopic surgical tool held dista~ly at the end of the device within the abdominal cavity adjacent that organ which is being excised or repaired.
Several implements are known which are useful to perform certain 5 surgical procedures. For example, U.S. Patent No. 2,898,915 discloses an implement for particularly tying off open blood vessels astringently. When the operating handle is suitably depressed, a catch is released so that the main slide member under the action of a spring will slide cluickly forward into the easing, allowing the tying head 10 of the implement to move over the forceps, with its front surface even extending slightly beyond. For a further device for ligaturing blood vessels see U.S. Patent No.
2,898,916 wherein by pressing the operating lever against the casing of the device, a second lever connected to the operating lever is moved laterally, and presses with a closing effect against a pivotally connected clamping arm so that it closes against a 5 stationary clamping arm, elamping the blood vessel elosed so that it may be ligatured.
However, these types of implements are not use-ful for imparting longitudinal and rotative movements to various endoseopie tools to manipulate their action during endoscopic surgery.

A still further embodiment of the present invention relates to a surgical instrurnent comprising:
a handle assembly including an axially directed stationary handle and a movable handle, the movable handle being pivotally connected to the stationary handle and being moveable from a ~irst position at an angle to the stationary handle to a second position in substantial parallel alignment with the stationary handle;
a body assembly comprising a pair of coaxial members attached at one 20 end to the handle assembly, including an inner rod member slidable within an elongated outer tube member in response to movement of the handle assembly, the body assembly terminating at an end remote from the handle assembly in a reciprocatingly movable tool mechanism~ and means positioned within the stationary handle of the handle assembly for engaging the body assembly to provide incremental movement of the tool mechamsm.
The device according to the present invention is a novel handle for a laparoscopic or endoscopic instrument which may, by imparting longitudinal and rotative motion selectively to a pair of concentric longitudinal shafts that extend outwardly frorn the handle, manipulate a distal laparoscopic surgical tool held at the opposite end of the shafts. In order to impart longitudinal motion to rnanipulate the distal laparoscopic surgical tool, the handle is provided with an axially aligned, elongated casing and a pivotally connected elongated grip member extending generally axially along the casing. The grip member, together with the casing, provide a pair of operating handles movable toward and away from each other. When the grip mernber is squeezed laterally inward, longitudinal movement is imparted to the inner, actuating shaft of the paired sha~ts. To impart longitudinal motion in a first direction, the grip member pivots from a first position laterally inward to a second position contacting along the casing and generally co-axial with the shafts.
The casing, into which the concentric shafts axially extend, encloses the details of the present invention. A link member pivotally interconnects the gripmember and a raclc attached at the enclosed end of the actuating shaft and located within the casing. The actuating shaft is connected to the racl~ so that it moves longitudinally with the rack. As the grip member is squeezed inward towards its second position, the link translates the pivotal motion of the grip member to longitudinal motion to impart a longitudinal movement to the rack and actuating shaft in the first direction toward the rear end of the casing. The longitudinal movement of 2~s~
the actuating shaft in the first direction, imparted by squeezing the grip member laterally inward toward its second position, causes a manipulative longitudinal movement to be applied to the distal laparoscopic surgical tool to perform a specified ' ~ :`
2~ i ~d~h'~i,~L.
surgical procedure. As may be appreciated, a longitudinal slot is provided in the casing through which the link member extends to allow the link to move longitudinally in the casing as the grip member is squeezed.
A detent enclosed within the casing allows the rack to slide therealong in the first direction so that the rack and attached actuating shaft may move longihldinally in the first direction. The detent engages with the rack to restrain longitudinal movement of the rack and attached actuating shaft in a second direction, opposite the Flrst direction, toward the front end of the casing. The detent and the rack cooperate to allow for incremental "ratcheting action" which allows the laparoscopic surgical tool to be selectively incrementally manipulated by squeezing the grip member inward in suitable increments towards its second position. Thus~ thetool may be advanced throu~h a series of incremental positions as the grip member is moved incrementally to its second position.
A release mechanism allows the rack and attached actuating shaft to move longitudinally in the second direction. As may be further appreciated, the release mechanism also allows the grip member and link member to return to theirfirst position. The release mechanism includes an elongated release member whichextends longitudinally into the casing. The release member is longitudinally movable from a first locking position by finger action to a second pOSitiOI1 to release the detent from its engagement with the rack. Included with the release mechanism, is a catch located on the detent which when engaged by the release member, allows the release member to disengage the detent from the rack. The catch is engaged by the enclosed end of the release member when the release member is moved to its second position, and, when the release member is moved to its second position allows the release member to disengage the detent *om the rack. In order to impart longitudinal motion to the actuating shaft and rack in the second direction when the release member is -6- 2~.~ J'~
moved to its second position, a spring located between the casing and the rack acts on the rear end of the rack to longitudinally move the actuating shaft and rack in the second direction. The longitudinal movement of the actuating shaft in the second5 direction, imparted by moving the release button to its second position, causes a further manipulative longitudinal movement to be applied to the clistal laparoscopic surgical tool to return the tool to its initial conf1guration.
~ thumb wheel is engaged with the outer shaft, and, when rotated, 1 O causes the shafts to rotate about their longitudinal axis. The rotational movement of the actuating shaft, imparted by rotating or turning the thumb wheel, causes a manipulative rotational movement to be applied to the distal laparoscopic surgical tool to perform a further specified surgical procedure. Accordingly, the manipulativerotational movement may be applied to rotate the laparoscopic tool in an arc about the longitudinal axis of the concentric shafts Consequently, the tool may not need to be repositioned in the body to access that bodily organ to be excised or repaired even though the tool may be initially deflected from its designated plane of operation.
Instead, rotation of the thumb wheel may allow the tool to be repositioned within the 20 desired oerating plane. The rotational motion may be applied either clockwise or counter-clockwise to align the surgical tool within the operating plane and to return the tool to its initial position.
Thus, after a trocar is partially inserted in the body, the laparoscopic 25 surgical tool attached at the distal end of the concentric shafts may be inserted through the cannula of tlle trocar and positioned adjacent the organ to be excised or repaired. With the aid of a laparoscope, the surgeon can manipulate the distal laparoscopic surgical tool by squee~ing the grip member laterally, in suitable increments, inward toward the casing and alignment with the axis of the concentric shafts to selectively apply longitudinal motion to the laparoscopic surgical tool. Thus, the tool may be selectively manipulated to perform a specific surgical procedure.
When the grip member is moved incrementally toward the casing, the detent and the rack cooperate to allow for the incremental "ratcheting action" which a]lows the5 ]aparoscopic surgical tool to be selectively incrementally manipulated.
Manipulation of the laparoscopic tool to position the surgical tool in the plane of operation may be performed by rotating the thumb wheel. As may be appreciated~ this may allow better use of the laparoscopic surgical tool. Pressing 10 inward on the push button end of the release member to disengage the detent from the rack, causes the laparoscopic surgical tool to return towards an initial configuration under spring influence.
13RIEF ~ESCRIPTION OF Tl-IE DRAWINGS
The foregoing features of the present invention will become more readily apparent and may be understood by referring to the following detailed description of a preferred embodiment of the handle according to the present invention, taken in 20 conjunction with the accompanying drawings, in which:
Fig. 1 illustrates a perspective view of a preferred embodiment of the handle for laparoscopic instrumentation according to the present invention;

~ -DETAILED DESCl~lPrION OF THE P~EFERREO El`/I~D~NT
~efelTing to Fig. 1, a preferred embodiment of the handle, shown 5 generally as 10, is shown. An elongated casing 12 encloses the essential parts of the invention, which are described in detail hereafter. Handle 10 is suilable for manipulating a distal laparoscopic or endoscopic surgical tool, not shown in thefigures, which is attached to the opposite, distal end of a pair of concentric 10 longitudinal shafts 14. Longitudinal shafts 14 extend outward]y from casing 12, and allow the distal laparoscopic surgical tool to be inserted tllrough a small incision in the body and positioned within the body adjacent the organ which is to be excised or repaired, thus allowing surgical procedures to be performed thereon without the need of severe incisions in adjacent body tissues. ~s discussed in detail hereafter, 15 concentric shafts 14 may comprise a longitudinally movable inner actuating shaft and an outer shaft, which allow the surgeon to control different types of endoscopic tools requiring reciprocal or rotational manipulations. Although it is preferred that concentric shafts 14 may comprise a longitudinally movable inncr shaft and an outer 20 shaft, it is within the scope of the invention that the outer shaft be longitudinally movable over the imler shaft.
An elongated grip member 16 is pivotally connected to casing 12.
Elongated casing 12 is aligned axially with concentric shafts 14 for purposes as25 discussed hereafter. By squeezing grip member 16 inward as described in detail hereafter, longitudinal motion may be transferred to the inner shaft. A thumb wheel 18 may be rotated selectively by the surgeon to impart rotary motion to the outer shaft, so that shafts 14 may be rotated about their longitudinal axis. As shown in Fig.
1, thumb wheel 18, may be carried within a pair of opposed slots 20 on opposite sides of casing 12.
Referring to Fig. 2 for details enclosed by casing 12, concentric shafts 14 extend longitudinally into casing 12 through an opening 22 in the front end of casing 12. Concentric shafts 14 include an inner longitudinal actuating shaft 24 and 5 an outer longitudinal tubular shaft 26, concentrically positioned around inner shaft 24.
Actuating shaft 24 extends longitudinally into casing 12 through a pair of opposed openings in inner walls 2~, 30. Included with actuating shaft is a rack 32 located in the rearward chamber 34 of casing 12 behind wall 30. ~ctuating shaft 24 connects at 1 0 its inner end to rack 32 by any suitable means so that actuating shaft 24 may be moved longitudinally by rack 32, as well as rotatably, if desired. Rack 32 is positioned so that its teeth 36 extend longitudinally along the axis of actuating shaft 24. Opening 38 in wall 30 through which actuating shaft 24 longitudinally extends may provide a bearing surface on which actuating shaft 24 may slide longitudinally, 1 5 while restraining lateral motion of actuating shaft 24 and rack 32. Attachable at the opposite, distal ends of shafts 24, 26 is a laparoscopic surgical tool, not shown in the figures, which may be manipulated by selective longitudinal and rotative motions of shafts 24, 26 to perform selected surgical procedures.
20 . As shown in Fig. 2, elongated grip member 16 is pivotally connected atone end to casing 12 by suitable means such as a pivot pin 40. Elongated casing 12 is aligned axially with concentric shafts 14, and grip member 16 extends generally axially along casing 12, as shown in Fig. 3, from its pivotal connection with casing 25 12 toward the rear of casing 12. Referring again to Fig. 2, grip member 16 and casing 12 together provide a pair of operating handles movable toward and away from each other. Consequently, a handle is provided which is aligned axially with the axis of the concentric shafts 14. Thus, the user may apply squeezing motion about thecommon axis of shafts 14. It is known to pIovide squeezable operating handles that are configured perpendicular to the axis of the concentric shafts. However, at times : ;
this handle configuration is diff1cult for the user to manipulate, which may lead to unpreferred delays in performing the necessary surg;cal procedure. However, as provided by the present inventioll, the ability to move grip member 16 and casing 12 5 toward and away from each other about the common axis of shafts 14 alleviates this problem and allows the user to more easily manipulate the surgical tool under more varied operating conditions. Thus, surgical procedures may be more timely and safely performed.
0 A link member 42 extends between grip member 16 and rack 32 and is pivotably connected to both at a pivot point. One end of link rnember 42 is pivotally connected on grip member 16 a suitable distance from its pivotal connection withcasing 12 by suitable means such as a pivot pin 44, and the opposite end of linkmember 42 is similarly attached to rack 32. Grip member 16 is pivotally movable 1 5 laterally relative to casing 12 from a f1rst position as shown in Fig. 2 inward in the direction of arrow 46 to a second position, not shown in the figures, co-axial with shafts 14, in which a planar surface 48 extending longitudinally along the lowersurface of grip member 16 contacts longitudinally along a similar planar surface 50 extending along casing 12. A longitudinal slot 51 in casing 12 allows link member 42 and rack 32 to move longitudinally in casing 12, and may include a cooperating flange and bevel system to provide a track in casing 12 in which rack 32 travels.
As grip member 16 is moved laterally inward toward its second position about its pivotal connection with casing 12, ]ink member 44 translates the pivotal motion of grip member 16 to longitudinal motion to move rack 32 longitudinally in a first direction as indicated by arrow 52 toward the end of casing 12. Movement of rack 32 longitudinally by the inward movement of grip member 16 toward its second position causes actuating shaft 24, connected thereto for movement therewith, to move longitudinally in the same direction as indicated by arrow 52. ~ovement of actuating shaft 24 longitudinally allows the laparoscopic surgical tool attached at the distal ends `' ''' ' of shafts 24, 26 to be manipulated by the longitudinai motion of actuating shaft 24 to provide a specified surgical procedure.
Extending along the upper surface of grip member 16 is an arcuate 5 convex section 54. Located opposite arcuate convex section and extending along the bottom surface of casing 12 is a similar symmetrical arcuate convex section 56.
Opposed arcuate convex sections 54, 56 are provided so that handle 10 may be more easily held and manipulated by the user to move the operating handles toward andO away from each other~ and it is apparent that these curved surfaces may be varied in length and height to provide for an anatomically comfortable grip.
Referring to Fig. 2, actuating shaft 24 may include a pair of axially aligned longitudinal shaft portions 57a, 57b. ~ connector in ~he form of a block 58, located between shaft portions 57a, 57b, may rotatively interconnect shaft portions 1 5 57a, 57b. Block 58 may rotatively connect with shaft portions 57a, 57b by any suitable means so that shaft portion 57a may rotate about its longitudinal axis. Block 58 is adapted to slide longitudinally within a notch 60 in wall 28. Preferably, notch 60 has a complementary shape to block 58. As shown in Fig. 2, block 58 may have 20 a square cross section, although other suitable cross sections such as triangular are also within the scope of the invention. ~s shown in Fig. 2, notch 60 has a complimentary square shape, but may have other suitable complementary cross sections to complement other cross sections of block 58 such as a triangular cross 25 section. Block 58 is further provided with a suitable longitudinal dimension such that block 58 remains positioned in notch 60 during the longitudinal movements of shaft 24. Alternatively, block 58 may be eliminated and shaft 24 may be rotatively connected directly to rack 32, such that a notch or circumferential groove is provided to allow for rotation of the shaft 24 while maintaining axial movement. Block 58 may further be adapted to releasably connect with shaft portion 57a so that shafts 14 may be disconnected from casing 12.
- 1 2 - ~,~w A detent provided in the form of a leaf spring 62 allows for the longitudinal movement of activating shaft 24 and rack 32 in the first direction while restraining the longitudinal movement of activating shaft 24 and rack 32 in a second, 5 opposite direction toward the front end of casing 12. Leaf spring 62 may be fixedly attached at its lower end within a lateral slot 64 in casing 12. Leaf spring 62 extends angularly from slot 64 upwards and toward the rear of casing 12, with its upper end bearing against rack 32. The angular e~tension of leaf spring 62 rearwardly allows teeth 36 of rack 32 to slide rearwardly in the rlrst direction across the upper,contacting end of leaf spring 62.
To restrain longitudinal movement of activating shaft 24 and rack 32 in the second or opposite direction, the upper end of leaf spring 62 biases against rack 32 and engages with the teeth 36 of rack 32 to prevent longitudinal movement of shaft 1 5 24 and rack 32 toward the front of casing 12. Leaf spring 62 and rack 32 cooperate to allow for incremental "ratcheting action" which allows the laparoscopic surgical tool to be selectively incrementally manipulated by squeezing grip member 16 inward in suitable increments towards its second position. Accordingly, the surgical tool may 20 go through a series of incremental positions as the tool is manipulated by the longitudinal motion of activating shaft 24. It is also contemplated that the pitch and spacing of the teeth 36 may be varied along the length of rack 32 to provide for fisle or s~oarse adjustment during opening and closing. The rearward end of the rack 32 25 may have teeth having greater spacing between them to allow for coarse adjustment, while the teeth at the forward end may be closely spaced to provide for fine adjustment.
To return the laparoscopic surgical tool to its initial position, handle lO
is provided with a release means for releasing leaf spring 62 from its engagement with rack 32 to allow longitudinal movement of the actuating shaft 24 in the second direction. In a preferred embodiment, the release means is provided by an elongated - 1 3 - 2 ~
release member or push button 66 and a catch 68 on leaf spring 62, which when engaged by the end of elongated member 66 when it is moved longitudinally to itssecond position as described hereafter, causes the upper end of leaf spring 62 to be 5 forced downwardly, thus disengaging leaf spring 62 from teeth 36 of rack 32 and allowing rack 32 and actuating shaft 24 to move longitudinally in the second direction toward the front of casing 12. As may further be appreciated, the release means also allows grip member 16 and link member 42 to return to their first position when 1 0 release member 66 is moved to its second position.
~ elease member 66 extends longitudinally through an opening 70 in ~he rear end of casing 12, where its exposed push button end may be manipulated by pushing to move release member 66 longit~Jdinally. :E~elease member 66 is positioned longitudinally within casing 12 so that its enclosed end may engage catch 68 when 1 5 release member 66 is moved to its second position. ~ ledge 72 extends sideways across rearward chamber 34 of casing 12 and prevents release member 66 from moving laterally.
To normally restrain rack 32 and actuating shaft 24 from moving 20 longitudirially in the second direction, biasing means in the form of a compression spring 74 is included with the illustrative release means. Spring 74 retains release member 66 in a first locking position, with its enclosed end disengaged from catch 68. Surrounding release member 66 near its exterior end is a shoulder 76. Spring 74 25 is located between rack 32 and shoulder 76, and acts against shoulder 76 to normally retain release member 66 locked in its first position, with its enclosed end disengaged from catch 68 as shown in Fig. 2. Spring 74 may be a constant force spring, or may also be a variable force spring in order to allow for easy movement at the beginning of the handle stroke and a harder movement at he end of the stroke to protect the tool mechanism at the end of the shafts.
When release member 66 is moved longitudinally inward toward the front of casing 12 to the second position by finger action pushing on the external portion of release member 66, the enclosed end of release member 66 engages withcatch 68 to force the upper end of leaf spring 62 downwardly, thus disengaging leaf spring 62 from the teeth 36 of rack 32 and allowing rack 32 and actuating shaft 24 to move longitudirlally in the second direction toward the front of casing 12.
Longitudinal movement of actuating shaft 24 and rack 32 in the second 1 0 direction toward the front of casing 12 may also be provided by the influence of spring 74. Referring to Fig. 2 for details, spring 74 is compressed longitudinally between rack 32 and shoulder 76. When leaf spring 62 is disenga~ed from teeth 36of rack 32 by the movement of release member 66 to its second position, spring 74 biases against the rearward face of rack 32, causin~ rack 32 and actuating shaft 24 to move longitudinally in the second direction toward the front of casing 12. Movement of actuating shaft 24 longitudinally in the second direction allows the laparoscopic surgical tool attached at the distal ends of shafts 24, 26 to be retumed by the longitudinal motion of actuating shaft 24 to their initial configuration.
In a preferred embodiment, concentric shafts 14 may be interconnected so that shafts 14 rotate together about their longitudinal axis. To allow concentric shafts 14 to rotate together, thumb wheel 18 may engage shaft 26 so that rotation of thumb wheel 18 causes shafts 14 to rotate. In a preferred embodiment, thumb wheel 18 may extend radially from shaft 26, and is suitably affixed thereto so that rotation of thumb wheel 18 causes shafts 14 to rotate to allow the laparoscopic surgical tool attached at tlle distal ends of shafts 24, 26 to be further manipulated in both clockwise and counter-clockwise directions to provide a further specified surgical procedure.
One preferred further manipulation is to apply the rotational movement to rotate the laparoscopic tool in an arc about the longitudinal axis of concentric shafts 14.Consequently, the tool may not need to be withdraw and repositioned in the body to -15 - 2 .
access that bodily organ to be excised or repaired, even though ~he tool may be initially defiected from its clesignated plane of operation. Instead, rotation of thumb wheel 18 may allow the tool to be repositioned within the desired operating plane.
In operation, a trocar is partially inserted into the body, and the distal laparoscopic surgical tool attached at the end of shafts 1~ of handle lO may be inserted through the cannula of the trocar and positioned laparoscopically adjacent the orgaul to be excised or repaired. With the aid of a laparoscope, not shown in the 10 ~;gures, the surgeon can manipulate the distal laparoscopic surgical tool by squeezing grip member 16 laterally inward toward casing 12 about the axis of longitudinal shafts 14 to apply longitudinal motion to the laparoscopic surgical tool to manipulate the tool to perform a specif1c surgical procedure. Manipulation of the laparoscopic surgical tool to best position the laparoscopic surgical tool in the plane of operation may be 15 performed by rotating thumb wheel 18 in clockwise or counter-clockwise directions.
Pressing inward on push button 66 to disengage leaf spring 62 from rack 32, causes the laparoscopic surgical tool to return towards an initial configuration under the influence of spring 74.
20 In addition, it is contemplated that release member 66 may be manipulated to disable leaf spring 62 to allow for free opening and closing of grip member 16 in relationship to casing 12.
While the invention has been particularly shown and described with 25 reference to a preferred embodiment, it will be understood by those skilled in the art that various modifications and changes in form and detail may be made therein without departing from the scope and spirit of the invention. ~ccordingly, modifications such as those suggested above, but not limited thereto, are to be considered within the scope of the invention.
A surgeon, when performing an operation on a patient, is often obstructed in his efforts to excise diseased or damaged tissues or organs by surrounding tissues~ fatty deposits, arteries, or other organs. It has generally been the case, when performing gastro intestinal surgery, i.e. surgery within the abdominal cavity, to make a large cut in the abdomen wall to produce a suitable opening to: ~ ~ allow access to the interior organs. This cut was generally large enough to allow the use of human hands, either those of the surgeons or those of a member of the surgical team, as a retractor. Surgical personnel would thus insert their hands through the incision into the abdominal cavity to push and hold organs and other obstructing components away from the surgical objective.

~ ecently, at least in part as a result of the evolution in electronic video technology, a surgical procedure known as laparoscopic surgery has undergone a marlced increase in popularity. The laparoscope consists of a long thin rigid tube, and 5 residing at one end of the tube is a viewing lens, while at the opposite end is a camera hook up and an eye piece. A small incision in the area of the surgical objective is made and the laparoscope is partially inserted into this incision, viewing lens first. High definition video cameras and monitors are then attached to the 10 camera hook up connector on the part of the laparoscope which remains positioned exteriorly of the body. In this manner, a surgical team can get a clear picture of the affected internal area without resorting to radical, disfiguring surgical incisions to physically open the patient. Other small incisions may then be made through the surface of the skin in the vicinity of the surgical objective. Through these incisions, 15 miniaturized surgical instruments such as scissors, forceps, clamps and scalpels may be inserted to perform various surgical procedures. The entire interiorly performed surgical procedure is monitored from the exterior through the high definition television monitor. In this manner radical incisions and scarring are avoided while 20 undertakin:g surgical repair or removal of damaged or diseased organs. Another benefit of laparoscopic surgery is the significantly reduced recovery time, whencompared to standard surgical procedures, due to the minuscule size of the scalpel incisions and avoiclance of the massive internal traumatization known in standard 25 surgical procedures. Accompanying the reduced recovery time are, of course, greatly reduced costs.
Therefore, there is a need to provide a clevice which may be partially inserted through a tiny surgical incision in the abdominal wall, which n-lay be used during laparoscopic surgery within the abdominal cavity, and which is useful to y~
manipulate an endoscopic surgical tool held dista~ly at the end of the device within the abdominal cavity adjacent that organ which is being excised or repaired.
Several implements are known which are useful to perform certain 5 surgical procedures. For example, U.S. Patent No. 2,898,915 discloses an implement for particularly tying off open blood vessels astringently. When the operating handle is suitably depressed, a catch is released so that the main slide member under the action of a spring will slide cluickly forward into the easing, allowing the tying head 10 of the implement to move over the forceps, with its front surface even extending slightly beyond. For a further device for ligaturing blood vessels see U.S. Patent No.
2,898,916 wherein by pressing the operating lever against the casing of the device, a second lever connected to the operating lever is moved laterally, and presses with a closing effect against a pivotally connected clamping arm so that it closes against a 5 stationary clamping arm, elamping the blood vessel elosed so that it may be ligatured.
However, these types of implements are not use-ful for imparting longitudinal and rotative movements to various endoseopie tools to manipulate their action during endoscopic surgery.

.

A still further embodiment of the present invention relates to a surgical instrurnent comprising:
a handle assembly including an axially directed stationary handle and a movable handle, the movable handle being pivotally connected to the stationary handle and being moveable from a ~irst position at an angle to the stationary handle to a second position in substantial parallel alignment with the stationary handle;
a body assembly comprising a pair of coaxial members attached at one 20 end to the handle assembly, including an inner rod member slidable within an elongated outer tube member in response to movement of the handle assembly, the body assembly terminating at an end remote from the handle assembly in a reciprocatingly movable tool mechanism~ and means positioned within the stationary handle of the handle assembly for engaging the body assembly to provide incremental movement of the tool mechamsm.
The device according to the present invention is a novel handle for a laparoscopic or endoscopic instrument which may, by imparting longitudinal and rotative motion selectively to a pair of concentric longitudinal shafts that extend outwardly frorn the handle, manipulate a distal laparoscopic surgical tool held at the opposite end of the shafts. In order to impart longitudinal motion to rnanipulate the distal laparoscopic surgical tool, the handle is provided with an axially aligned, elongated casing and a pivotally connected elongated grip member extending generally axially along the casing. The grip member, together with the casing, provide a pair of operating handles movable toward and away from each other. When the grip mernber is squeezed laterally inward, longitudinal movement is imparted to the inner, actuating shaft of the paired sha~ts. To impart longitudinal motion in a first direction, the grip member pivots from a first position laterally inward to a second position contacting along the casing and generally co-axial with the shafts.
The casing, into which the concentric shafts axially extend, encloses the details of the present invention. A link member pivotally interconnects the gripmember and a raclc attached at the enclosed end of the actuating shaft and located within the casing. The actuating shaft is connected to the racl~ so that it moves longitudinally with the rack. As the grip member is squeezed inward towards its second position, the link translates the pivotal motion of the grip member to longitudinal motion to impart a longitudinal movement to the rack and actuating shaft in the first direction toward the rear end of the casing. The longitudinal movement of 2~s~
the actuating shaft in the first direction, imparted by squeezing the grip member laterally inward toward its second position, causes a manipulative longitudinal movement to be applied to the distal laparoscopic surgical tool to perform a specified ' ~ :`
2~ i ~d~h'~i,~L.
surgical procedure. As may be appreciated, a longitudinal slot is provided in the casing through which the link member extends to allow the link to move longitudinally in the casing as the grip member is squeezed.
A detent enclosed within the casing allows the rack to slide therealong in the first direction so that the rack and attached actuating shaft may move longihldinally in the first direction. The detent engages with the rack to restrain longitudinal movement of the rack and attached actuating shaft in a second direction, opposite the Flrst direction, toward the front end of the casing. The detent and the rack cooperate to allow for incremental "ratcheting action" which allows the laparoscopic surgical tool to be selectively incrementally manipulated by squeezing the grip member inward in suitable increments towards its second position. Thus~ thetool may be advanced throu~h a series of incremental positions as the grip member is moved incrementally to its second position.
A release mechanism allows the rack and attached actuating shaft to move longitudinally in the second direction. As may be further appreciated, the release mechanism also allows the grip member and link member to return to theirfirst position. The release mechanism includes an elongated release member whichextends longitudinally into the casing. The release member is longitudinally movable from a first locking position by finger action to a second pOSitiOI1 to release the detent from its engagement with the rack. Included with the release mechanism, is a catch located on the detent which when engaged by the release member, allows the release member to disengage the detent from the rack. The catch is engaged by the enclosed end of the release member when the release member is moved to its second position, and, when the release member is moved to its second position allows the release member to disengage the detent *om the rack. In order to impart longitudinal motion to the actuating shaft and rack in the second direction when the release member is -6- 2~.~ J'~
moved to its second position, a spring located between the casing and the rack acts on the rear end of the rack to longitudinally move the actuating shaft and rack in the second direction. The longitudinal movement of the actuating shaft in the second5 direction, imparted by moving the release button to its second position, causes a further manipulative longitudinal movement to be applied to the clistal laparoscopic surgical tool to return the tool to its initial conf1guration.
~ thumb wheel is engaged with the outer shaft, and, when rotated, 1 O causes the shafts to rotate about their longitudinal axis. The rotational movement of the actuating shaft, imparted by rotating or turning the thumb wheel, causes a manipulative rotational movement to be applied to the distal laparoscopic surgical tool to perform a further specified surgical procedure. Accordingly, the manipulativerotational movement may be applied to rotate the laparoscopic tool in an arc about the longitudinal axis of the concentric shafts Consequently, the tool may not need to be repositioned in the body to access that bodily organ to be excised or repaired even though the tool may be initially deflected from its designated plane of operation.
Instead, rotation of the thumb wheel may allow the tool to be repositioned within the 20 desired oerating plane. The rotational motion may be applied either clockwise or counter-clockwise to align the surgical tool within the operating plane and to return the tool to its initial position.
Thus, after a trocar is partially inserted in the body, the laparoscopic 25 surgical tool attached at the distal end of the concentric shafts may be inserted through the cannula of tlle trocar and positioned adjacent the organ to be excised or repaired. With the aid of a laparoscope, the surgeon can manipulate the distal laparoscopic surgical tool by squee~ing the grip member laterally, in suitable increments, inward toward the casing and alignment with the axis of the concentric shafts to selectively apply longitudinal motion to the laparoscopic surgical tool. Thus, the tool may be selectively manipulated to perform a specific surgical procedure.
When the grip member is moved incrementally toward the casing, the detent and the rack cooperate to allow for the incremental "ratcheting action" which a]lows the5 ]aparoscopic surgical tool to be selectively incrementally manipulated.
Manipulation of the laparoscopic tool to position the surgical tool in the plane of operation may be performed by rotating the thumb wheel. As may be appreciated~ this may allow better use of the laparoscopic surgical tool. Pressing 10 inward on the push button end of the release member to disengage the detent from the rack, causes the laparoscopic surgical tool to return towards an initial configuration under spring influence.
13RIEF ~ESCRIPTION OF Tl-IE DRAWINGS
The foregoing features of the present invention will become more readily apparent and may be understood by referring to the following detailed description of a preferred embodiment of the handle according to the present invention, taken in 20 conjunction with the accompanying drawings, in which:
Fig. 1 illustrates a perspective view of a preferred embodiment of the handle for laparoscopic instrumentation according to the present invention;

~ -DETAILED DESCl~lPrION OF THE P~EFERREO El`/I~D~NT
~efelTing to Fig. 1, a preferred embodiment of the handle, shown 5 generally as 10, is shown. An elongated casing 12 encloses the essential parts of the invention, which are described in detail hereafter. Handle 10 is suilable for manipulating a distal laparoscopic or endoscopic surgical tool, not shown in thefigures, which is attached to the opposite, distal end of a pair of concentric 10 longitudinal shafts 14. Longitudinal shafts 14 extend outward]y from casing 12, and allow the distal laparoscopic surgical tool to be inserted tllrough a small incision in the body and positioned within the body adjacent the organ which is to be excised or repaired, thus allowing surgical procedures to be performed thereon without the need of severe incisions in adjacent body tissues. ~s discussed in detail hereafter, 15 concentric shafts 14 may comprise a longitudinally movable inner actuating shaft and an outer shaft, which allow the surgeon to control different types of endoscopic tools requiring reciprocal or rotational manipulations. Although it is preferred that concentric shafts 14 may comprise a longitudinally movable inncr shaft and an outer 20 shaft, it is within the scope of the invention that the outer shaft be longitudinally movable over the imler shaft.
An elongated grip member 16 is pivotally connected to casing 12.
Elongated casing 12 is aligned axially with concentric shafts 14 for purposes as25 discussed hereafter. By squeezing grip member 16 inward as described in detail hereafter, longitudinal motion may be transferred to the inner shaft. A thumb wheel 18 may be rotated selectively by the surgeon to impart rotary motion to the outer shaft, so that shafts 14 may be rotated about their longitudinal axis. As shown in Fig.
1, thumb wheel 18, may be carried within a pair of opposed slots 20 on opposite sides of casing 12.
Referring to Fig. 2 for details enclosed by casing 12, concentric shafts 14 extend longitudinally into casing 12 through an opening 22 in the front end of casing 12. Concentric shafts 14 include an inner longitudinal actuating shaft 24 and 5 an outer longitudinal tubular shaft 26, concentrically positioned around inner shaft 24.
Actuating shaft 24 extends longitudinally into casing 12 through a pair of opposed openings in inner walls 2~, 30. Included with actuating shaft is a rack 32 located in the rearward chamber 34 of casing 12 behind wall 30. ~ctuating shaft 24 connects at 1 0 its inner end to rack 32 by any suitable means so that actuating shaft 24 may be moved longitudinally by rack 32, as well as rotatably, if desired. Rack 32 is positioned so that its teeth 36 extend longitudinally along the axis of actuating shaft 24. Opening 38 in wall 30 through which actuating shaft 24 longitudinally extends may provide a bearing surface on which actuating shaft 24 may slide longitudinally, 1 5 while restraining lateral motion of actuating shaft 24 and rack 32. Attachable at the opposite, distal ends of shafts 24, 26 is a laparoscopic surgical tool, not shown in the figures, which may be manipulated by selective longitudinal and rotative motions of shafts 24, 26 to perform selected surgical procedures.
20 . As shown in Fig. 2, elongated grip member 16 is pivotally connected atone end to casing 12 by suitable means such as a pivot pin 40. Elongated casing 12 is aligned axially with concentric shafts 14, and grip member 16 extends generally axially along casing 12, as shown in Fig. 3, from its pivotal connection with casing 25 12 toward the rear of casing 12. Referring again to Fig. 2, grip member 16 and casing 12 together provide a pair of operating handles movable toward and away from each other. Consequently, a handle is provided which is aligned axially with the axis of the concentric shafts 14. Thus, the user may apply squeezing motion about thecommon axis of shafts 14. It is known to pIovide squeezable operating handles that are configured perpendicular to the axis of the concentric shafts. However, at times : ;
this handle configuration is diff1cult for the user to manipulate, which may lead to unpreferred delays in performing the necessary surg;cal procedure. However, as provided by the present inventioll, the ability to move grip member 16 and casing 12 5 toward and away from each other about the common axis of shafts 14 alleviates this problem and allows the user to more easily manipulate the surgical tool under more varied operating conditions. Thus, surgical procedures may be more timely and safely performed.
0 A link member 42 extends between grip member 16 and rack 32 and is pivotably connected to both at a pivot point. One end of link rnember 42 is pivotally connected on grip member 16 a suitable distance from its pivotal connection withcasing 12 by suitable means such as a pivot pin 44, and the opposite end of linkmember 42 is similarly attached to rack 32. Grip member 16 is pivotally movable 1 5 laterally relative to casing 12 from a f1rst position as shown in Fig. 2 inward in the direction of arrow 46 to a second position, not shown in the figures, co-axial with shafts 14, in which a planar surface 48 extending longitudinally along the lowersurface of grip member 16 contacts longitudinally along a similar planar surface 50 extending along casing 12. A longitudinal slot 51 in casing 12 allows link member 42 and rack 32 to move longitudinally in casing 12, and may include a cooperating flange and bevel system to provide a track in casing 12 in which rack 32 travels.
As grip member 16 is moved laterally inward toward its second position about its pivotal connection with casing 12, ]ink member 44 translates the pivotal motion of grip member 16 to longitudinal motion to move rack 32 longitudinally in a first direction as indicated by arrow 52 toward the end of casing 12. Movement of rack 32 longitudinally by the inward movement of grip member 16 toward its second position causes actuating shaft 24, connected thereto for movement therewith, to move longitudinally in the same direction as indicated by arrow 52. ~ovement of actuating shaft 24 longitudinally allows the laparoscopic surgical tool attached at the distal ends `' ''' ' of shafts 24, 26 to be manipulated by the longitudinai motion of actuating shaft 24 to provide a specified surgical procedure.
Extending along the upper surface of grip member 16 is an arcuate 5 convex section 54. Located opposite arcuate convex section and extending along the bottom surface of casing 12 is a similar symmetrical arcuate convex section 56.
Opposed arcuate convex sections 54, 56 are provided so that handle 10 may be more easily held and manipulated by the user to move the operating handles toward andO away from each other~ and it is apparent that these curved surfaces may be varied in length and height to provide for an anatomically comfortable grip.
Referring to Fig. 2, actuating shaft 24 may include a pair of axially aligned longitudinal shaft portions 57a, 57b. ~ connector in ~he form of a block 58, located between shaft portions 57a, 57b, may rotatively interconnect shaft portions 1 5 57a, 57b. Block 58 may rotatively connect with shaft portions 57a, 57b by any suitable means so that shaft portion 57a may rotate about its longitudinal axis. Block 58 is adapted to slide longitudinally within a notch 60 in wall 28. Preferably, notch 60 has a complementary shape to block 58. As shown in Fig. 2, block 58 may have 20 a square cross section, although other suitable cross sections such as triangular are also within the scope of the invention. ~s shown in Fig. 2, notch 60 has a complimentary square shape, but may have other suitable complementary cross sections to complement other cross sections of block 58 such as a triangular cross 25 section. Block 58 is further provided with a suitable longitudinal dimension such that block 58 remains positioned in notch 60 during the longitudinal movements of shaft 24. Alternatively, block 58 may be eliminated and shaft 24 may be rotatively connected directly to rack 32, such that a notch or circumferential groove is provided to allow for rotation of the shaft 24 while maintaining axial movement. Block 58 may further be adapted to releasably connect with shaft portion 57a so that shafts 14 may be disconnected from casing 12.
- 1 2 - ~,~w A detent provided in the form of a leaf spring 62 allows for the longitudinal movement of activating shaft 24 and rack 32 in the first direction while restraining the longitudinal movement of activating shaft 24 and rack 32 in a second, 5 opposite direction toward the front end of casing 12. Leaf spring 62 may be fixedly attached at its lower end within a lateral slot 64 in casing 12. Leaf spring 62 extends angularly from slot 64 upwards and toward the rear of casing 12, with its upper end bearing against rack 32. The angular e~tension of leaf spring 62 rearwardly allows teeth 36 of rack 32 to slide rearwardly in the rlrst direction across the upper,contacting end of leaf spring 62.
To restrain longitudinal movement of activating shaft 24 and rack 32 in the second or opposite direction, the upper end of leaf spring 62 biases against rack 32 and engages with the teeth 36 of rack 32 to prevent longitudinal movement of shaft 1 5 24 and rack 32 toward the front of casing 12. Leaf spring 62 and rack 32 cooperate to allow for incremental "ratcheting action" which allows the laparoscopic surgical tool to be selectively incrementally manipulated by squeezing grip member 16 inward in suitable increments towards its second position. Accordingly, the surgical tool may 20 go through a series of incremental positions as the tool is manipulated by the longitudinal motion of activating shaft 24. It is also contemplated that the pitch and spacing of the teeth 36 may be varied along the length of rack 32 to provide for fisle or s~oarse adjustment during opening and closing. The rearward end of the rack 32 25 may have teeth having greater spacing between them to allow for coarse adjustment, while the teeth at the forward end may be closely spaced to provide for fine adjustment.
To return the laparoscopic surgical tool to its initial position, handle lO
is provided with a release means for releasing leaf spring 62 from its engagement with rack 32 to allow longitudinal movement of the actuating shaft 24 in the second direction. In a preferred embodiment, the release means is provided by an elongated - 1 3 - 2 ~
release member or push button 66 and a catch 68 on leaf spring 62, which when engaged by the end of elongated member 66 when it is moved longitudinally to itssecond position as described hereafter, causes the upper end of leaf spring 62 to be 5 forced downwardly, thus disengaging leaf spring 62 from teeth 36 of rack 32 and allowing rack 32 and actuating shaft 24 to move longitudinally in the second direction toward the front of casing 12. As may further be appreciated, the release means also allows grip member 16 and link member 42 to return to their first position when 1 0 release member 66 is moved to its second position.
~ elease member 66 extends longitudinally through an opening 70 in ~he rear end of casing 12, where its exposed push button end may be manipulated by pushing to move release member 66 longit~Jdinally. :E~elease member 66 is positioned longitudinally within casing 12 so that its enclosed end may engage catch 68 when 1 5 release member 66 is moved to its second position. ~ ledge 72 extends sideways across rearward chamber 34 of casing 12 and prevents release member 66 from moving laterally.
To normally restrain rack 32 and actuating shaft 24 from moving 20 longitudirially in the second direction, biasing means in the form of a compression spring 74 is included with the illustrative release means. Spring 74 retains release member 66 in a first locking position, with its enclosed end disengaged from catch 68. Surrounding release member 66 near its exterior end is a shoulder 76. Spring 74 25 is located between rack 32 and shoulder 76, and acts against shoulder 76 to normally retain release member 66 locked in its first position, with its enclosed end disengaged from catch 68 as shown in Fig. 2. Spring 74 may be a constant force spring, or may also be a variable force spring in order to allow for easy movement at the beginning of the handle stroke and a harder movement at he end of the stroke to protect the tool mechanism at the end of the shafts.
When release member 66 is moved longitudinally inward toward the front of casing 12 to the second position by finger action pushing on the external portion of release member 66, the enclosed end of release member 66 engages withcatch 68 to force the upper end of leaf spring 62 downwardly, thus disengaging leaf spring 62 from the teeth 36 of rack 32 and allowing rack 32 and actuating shaft 24 to move longitudirlally in the second direction toward the front of casing 12.
Longitudinal movement of actuating shaft 24 and rack 32 in the second 1 0 direction toward the front of casing 12 may also be provided by the influence of spring 74. Referring to Fig. 2 for details, spring 74 is compressed longitudinally between rack 32 and shoulder 76. When leaf spring 62 is disenga~ed from teeth 36of rack 32 by the movement of release member 66 to its second position, spring 74 biases against the rearward face of rack 32, causin~ rack 32 and actuating shaft 24 to move longitudinally in the second direction toward the front of casing 12. Movement of actuating shaft 24 longitudinally in the second direction allows the laparoscopic surgical tool attached at the distal ends of shafts 24, 26 to be retumed by the longitudinal motion of actuating shaft 24 to their initial configuration.
In a preferred embodiment, concentric shafts 14 may be interconnected so that shafts 14 rotate together about their longitudinal axis. To allow concentric shafts 14 to rotate together, thumb wheel 18 may engage shaft 26 so that rotation of thumb wheel 18 causes shafts 14 to rotate. In a preferred embodiment, thumb wheel 18 may extend radially from shaft 26, and is suitably affixed thereto so that rotation of thumb wheel 18 causes shafts 14 to rotate to allow the laparoscopic surgical tool attached at tlle distal ends of shafts 24, 26 to be further manipulated in both clockwise and counter-clockwise directions to provide a further specified surgical procedure.
One preferred further manipulation is to apply the rotational movement to rotate the laparoscopic tool in an arc about the longitudinal axis of concentric shafts 14.Consequently, the tool may not need to be withdraw and repositioned in the body to -15 - 2 .
access that bodily organ to be excised or repaired, even though ~he tool may be initially defiected from its clesignated plane of operation. Instead, rotation of thumb wheel 18 may allow the tool to be repositioned within the desired operating plane.
In operation, a trocar is partially inserted into the body, and the distal laparoscopic surgical tool attached at the end of shafts 1~ of handle lO may be inserted through the cannula of the trocar and positioned laparoscopically adjacent the orgaul to be excised or repaired. With the aid of a laparoscope, not shown in the 10 ~;gures, the surgeon can manipulate the distal laparoscopic surgical tool by squeezing grip member 16 laterally inward toward casing 12 about the axis of longitudinal shafts 14 to apply longitudinal motion to the laparoscopic surgical tool to manipulate the tool to perform a specif1c surgical procedure. Manipulation of the laparoscopic surgical tool to best position the laparoscopic surgical tool in the plane of operation may be 15 performed by rotating thumb wheel 18 in clockwise or counter-clockwise directions.
Pressing inward on push button 66 to disengage leaf spring 62 from rack 32, causes the laparoscopic surgical tool to return towards an initial configuration under the influence of spring 74.
20 In addition, it is contemplated that release member 66 may be manipulated to disable leaf spring 62 to allow for free opening and closing of grip member 16 in relationship to casing 12.
While the invention has been particularly shown and described with 25 reference to a preferred embodiment, it will be understood by those skilled in the art that various modifications and changes in form and detail may be made therein without departing from the scope and spirit of the invention. ~ccordingly, modifications such as those suggested above, but not limited thereto, are to be considered within the scope of the invention.
