Definitions
- the present invention pertains to suturing of bodily or anatomical tissue and, more particularly, to an apparatus and method for suturing anatomical tissue during endoscopic and open surgical procedures. Discussion of the Related Art:
- Suturing of bodily tissue that is, the practice of using lengths of suture material to ligate or approximate tissue, is a time consuming part of most surgical procedures including both open surgery and endoscopic or closed surgery.
- Open surgery refers to surgery wherein the surgeon gains access to the surgical site by a relatively large incision
- endoscopic surgery refers to minimally invasive surgery wherein the surgeon gains access to the surgical site via one or more portals through which endoscopes are introduced to view the surgical site and through which instruments, such as forceps, cutters, needle holders and the like, are introduced to the surgical site.
- suturing has been accomplished with the use of a sharp suture needle carrying a length of suture material, the suture needle being caused to penetrate and pass through the tissue pulling the suture material through the tissue.
- the surgeon ties a knot in the suture material. The knotting procedure allows the surgeon to adjust the tension on the suture material to accommodate the particular tissue being sutured and to control approximation, occlusion, attachment or other conditions of the tissue.
- the performance of an endoscopic procedure typically involves creation of one or more puncture sites through a wall of an anatomical cavity using a penetrating instrument including an obturator, such as a trocar, disposed within a portal sleeve.
- a penetrating instrument including an obturator, such as a trocar, disposed within a portal sleeve.
- the obturator is withdrawn leaving the sleeve in place to form a portal in the cavity wall for the introduction of instruments such as endoscopes, scissors, forceps, needle holders and the like (known generally as "end effectors") into the anatomical cavity.
- Suturing is typically performed with a needle holding instrument, or needle holder, having a pair of jaws adapted to hold the body of a suture needle.
- the jaws of the needle holding instrument are inserted through the portal sleeve and are positioned at the operative site by manipulation of a handle at the proximal end of the instrument outside the body.
- the handle With a suture needle held between the jaws of the needle holding instrument, the handle is manipulated to cause a tip of the needle to be pushed through the tissue being sutured.
- the jaws of the needle holding instrument are opened to release the suture needle so that the tip of the needle can be grasped and pulled through the tissue therewith, or, after opening the jaws, a second needle holding instrument is introduced at the operative site through another portal to grasp the tip of the suture needle after it has emerged from the tissue being sutured.
- the device disclosed in this pending application has a working span that is confined within the diametrical limitations of the endoscopic device. This can present difficulties when large portions of tissue are to be sutured.
- U.S. Patent No. 5,582,617 discloses an endoscopic instrument having an end effector that can move from a position within the diameter of the barrel of the device to a position outside the diameter.
- this device must pivot about an axis that is transverse to the axis of the barrel and an axis that is coincident with the axis of the barrel and thus requires a complex movement and linkage to accomplish the disclosed functions. Accordingly, this device falls short of providing a needle holder that can be utilized over a large working span.
- the present invention allows suturing of anatomical tissue to be accomplished in a time efficient, consistent and precise manner. Also, suturing can be accomplished using standard suture needles and filamentous suture materials without the need for additional instruments at the operative site.
- a first aspect of the present invention is generally characterized in an instrument for suturing anatomical tissue with a suture needle including a barrel, a needle holder having a shaft that is mounted in the barrel for rotation about an axis.
- the needle holder shaft has needle holding jaw members offset from the axis and selectively operable to grasp and release the suture needle.
- the jaw members are coupled to the shaft by arms or connecting portions extending from a distal end of the shafts.
- the needle holder can be rotated to drive the suture needle through a path having a large radius of curvature to penetrate anatomical tissue.
- the jaw members are contained within a diametrical dimension of the device. However during suturing, the jaw members can extend beyond this dimension due to the offset configuration.
- Another aspect of the present invention is generally characterized in a method of suturing anatomical tissue using a length of suture material attached to a suture needle.
- the method includes the steps of grasping the suture needle with offset jaw members of a needle holder, rotating the needle holder in a first direction to cause the tip of the needle to penetrate the anatomical tissue, releasing the suture needle from the needle holder, rotating the needle holder in a second direction to grasp the needle tip, and rotating the needle holder in the first direction again to pull the needle and the suture material through the anatomical tissue.
- a needle holder having offset jaw members is combined with a ligating instrument in a single endoscopic device.
- the ligating instrument carries one or more loops of suture material that can be drawn tightly around a knotting element or the like to secure suture material after the suture material has been passed through the tissue by the needle driver.
- the ligating instrument is inserted through an operating channel formed in the shaft of the needle holder.

- the suturing instrument of the present invention can be utilized to suture any type of anatomical tissue in any type of anatomical cavity. Accordingly, while the instrument is described hereinafter for use with a portal sleeve in endoscopic procedures, such as laparoscopy, the instrument can be used in open surgery and with catheters and other small and large diameter tubular or hollow cylindrical members providing access to small cavities, such as veins and arteries, as well as large cavities, such as the abdomen.
- a suturing instrument according to a first preferred embodiment of the present invention is illustrated at 30 in Fig. 1 and includes cylindrical barrel 32 which has an elongated passage defined therein, and needle holder 40. Needle holder 40 is substantially contained within cylindrical barrel 32 as is described in detail below.
- barrel 32 includes channels 38a and 38b extending longitudinally therethrough.
- Barrel 32 can have additional channels for receiving one or more additional instruments to be introduced in the abdominal cavity or the barrel 32 can have only one channel as needed.
- a plurality of light transmitting fibers 39 can be disposed in barrel 32 for transmitting light from a proximal light source to an anatomical cavity.
- Channels 38a and 38b can be formed by thin wall, tubular sleeves extending longitudinally through barrel 32 or can be merely void spaces defined by light transmitting fibers 39.
- Needle holder 40 includes elongated, tubular outer member 42, and elongated tubular inner member 44 disposed within outer member 42.
- Outer member 42 and inner member 44 define a shaft that is rotatable in barrel 32.
- Outer member 42 has a proximal end on which two diametrically enlarged flanges 46 are disposed.
- Flanges 46 serve to fix collar 48 on outer member 42 while permitting collar 48 to rotate with respect to outer member 42. The purpose and function of collar 48 is described below.
- Arms 51 A and 51 B extend from a distal end of inner member 44 to serve as a connecting member between inner member 44 and jaw members 50A and 50B formed on a free end of arms 51 A and 51 B respectively.
- a longitudinal axis of jaw members 50A and 50B is offset from a longitudinal axis of the shaft defined by inner member 44 and outer member 42.
- Jaw members 50A and 50B are normally biased to an open position wherein jaw members 50A and 50B have a gap defined therebetween. This permits the shank of a suture needle to be placed between jaw members 50A and 50B to be grasped thereby.
- jaw members 50A and 50B can be shaped to correspond to the needle shank, or any other appropriate way, to firmly grasp the needle when the jaw members 50A and 50B are in a closed position as shown in Figs. 3A and 3B.
- Needle holder 40 can be designed in various known ways permitting jaw members 50A and 50B to be movable between the closed position and the open position.
- the arms 51 A and 51 B can be made entirely or partly of resilient, flexible or spring materials, or materials having shape memory, to be resiliently biased toward the open position while being movable to the closed position and back to the open position.
- Figure 5B illustrates an alternative needle holder 40 having pivoting jaw members 50A and 50B.
- Figure 5C illustrates an alternative needle driver apparatus 40 having flexible inner member 44 that grasps a needle in a notch formed in outer member 42 when advanced distally.
- Figure 5D illustrates another alternative needle driver apparatus 40 that is resiliently flexible and can be drawn into barrel 32. In a free state, a distal end of needle driver apparatus 40 of Fig. 5D is angled.
- Fig. 5E illustrates a distal end of instrument 30 having a needle holder that includes hooked member 41 and sliding keeper 43 that can be moved distally and proximally with respect to hook member 41.
- a needle can be grasped when keeper 43 is advanced distally to the closed position illustrated in Fig. 5F.
- Fig. 5G illustrates a similar arrangement. However, hook member 41 opens outwardly.
- Fig. 5H shows the open position with keeper 43 withdrawn.
- Fig. 5K illustrates a distal end of instrument 30 having a needle holder that is configured as illustrated in Fig. 5C.
- Fig. 5L illustrates a similar configuration. However, in Fig. 5L, the notch in outer member 42 opens outwardly.
- proximal controls 60 of the preferred embodiment include handles 62 and 64 extending from housing 79 disposed on barrel 32.
- Button 66 is provided proximate an axis of rotation of handles 62 and 64. Depressing button 66 disengages handles 62 and 64 from driver apparatus 40 and permits handles 62 and 64 to be rotated in concert about the axis of rotation as indicated by arrow A in Fig. 1. This allows the surgeon to orient handles 62 and 64 in a desired manner prior to or during surgery.
- Figs. 4A and 4B illustrate the internal mechanism coupling handles 62 and 64 to driver apparatus 40.
- Operating member 72 is rotatably disposed on shaft 71 and has gear portion 74 that is engaged with collar 48 on outer member 42 of driver apparatus 40. Operating member 72 is fixed axial ly on shaft 71 and has radially extending serrated teeth 73 formed on a side opposite gear portion 74.
- Handle 62 is also rotatably mounted on shaft 71 and is slidable relative to shaft 80. Handle 62 is fixed in axial position by projections formed on an inner surface of housing 79. Handle 62 has radially extending serrated teeth 75 on each side thereof at a top portion that is disposed around shaft 71. Shaft 71 is mounted on stem 78 and is normally biased to the right in Fig. 4A by spring 76 to press serrated teeth 73 into engagement with serrated teeth 75 thus fixing the relative position of operating member 72 and handle 62. Handle 64 is rotatably mounted on shaft 71 and fixed axially on shaft 71.
- cam surfaces 52A and 52B are formed on outer surfaces of arms 51 A and 51 B respectively.
- outer member 42 moves distally over cam surfaces 52A and 52B causing jaw members 50A and 50B to move toward one another to the closed position.
- Cam surfaces 52A and 52B can be formed by bent portions defined in legs 51 A and 52B or by separate elements that are attached to, or formed on, legs 51 A and 51 B. Release of handles 62 and 64 causes jaw members 50A and 50B to return to the open position due to the resilient bias of arms 51 A and 51 B.
- Lock protrusions 63 and 65 are disposed on handles 62 and 64 respectively (see Fig.
- handles 62 and 64 are serrated to interlock and allow the position of handles 62 and 64 to be maintained in a state corresponding to a desired position of jaw members 50A and 50B.
- Lock protrusions 63 and 65 can be pivoted to a position of which they will not interlock if desired.
- handles 62 and 64 can be biased apart or outer member 44 can be biased distally or proximally, depending on desired operating characteristics.
- housing 79 can be rotatable to permit a greater degree of handle adjustment.
- the shaft of needle holder 40 is disposed in channel 38b to extend through barrel 32 and can be rotated about a longitudinal axis relative to barrel 32 by rotating knob 48 which is coupled to outer member 42 by a gear or the like.
- Button 49 is provided to lock knob 48. Depressing button 49 releases the locked state of knob 48.
- Knob 48 can be coupled to needle holder 40 in any appropriate manner, such as by a gear as disclosed in pending U.S. application Serial No. 08/847,189 entitled "Surgical Instrument with Multiple Rotatably Mounted Offset End Effectors and Method of Using the Same", the disclosure of which is incorporated herein by reference.
- a known optical observation device such as an optical endoscope using fiber optics or a CCD device for transmitting an image from the distal end to the proximal end, can be inserted in channel 38a, through proximal aperture 92 (see Fig. 1 ), for permitting observation of the operation of the other elements.
- Additional channels can be provided for a suction device, an irrigation device, or any other appropriate instrument.
- suturing device 30 is inserted into a body cavity using known techniques, while needle holder 40 is in the insertion position, or parked position, illustrated in Figs. 3A and 3B. Note that the entire device can be inserted through a single puncture site. Also, in the insertion position, jaw members 50A and 50B as well as needle N are disposed within the diametrical dimension of barrel 32 because of the position of arms 51 A and 51 B. The distal end of suturing device 30 is guided to the operative site through a portal sleeve positioned in the wall of an anatomical cavity.
- the portal sleeve can be positioned in the anatomical cavity wall using any suitable penetrating technique, including those creating puncture sites by means of removable obturators, such as trocars, and can include a valve housing, if desired, to prevent loss of pneumoperitoneum during insertion and withdrawal of the instrument.
- a retractable tubular sheath 55 (shown with dotted lines in Fig. 3B), or any other appropriate structure, can cover the distal end during insertion to facilitate insertion and prevent damage to a valve housing or the like.
- Visualization of the endoscopic procedure can be accomplished using a conventional endoscope incorporated into the channel 18a as noted above (i.e. a single puncture operation) or separately positioned within the anatomical cavity through a second portal sleeve located at another puncture site (i.e. a double puncture operation).
- needle N is held tightly between jaw members 50A and 50B of needle driver apparatus 40.
- a detent device such as serrated projections 63 and 65 illustrated in Fig. 1 , can be provided to selectively maintain jaws 50A and 50B in a position holding the needle while freeing the operator's hands for other manipulation.
- needle N can be introduced into the body cavity by a separate instrument through a separate puncture sight.
- needle N is of a semi-circular configuration.
- needle N can be straight or of any other appropriate shape.
- Figs. 6A and 6B which illustrate a suturing process
- the shaft of needle holder 40 is rotated, by rotating knob 48 or barrel 32, from the insertion position, in a counter-clockwise direction, as viewed in Figs. 6A and 6B to the position indicated by the dotted line in Fig. 6A.
- a backing device B is placed behind tissue T to support tissue T.
- Backup device B can be inserted through a separate portal or the like or can be inserted through operating channel 38a or another operating channel formed in barrel 32, or can be fixed to barrel 32.
- the shaft of needle driver apparatus 40 is rotated further in a counter-clockwise direction, by rotating knob 48 or barrel 32, to drive a tip of needle N through a portion of the tissue T while the tissue T is supported from an opposite side by backup device B as illustrated by the solid lines in Fig. 6A.
- Jaw members 50A and 50B are then placed in the open position, by releasing serrated projections 63 and 65 or otherwise permitting handles 62 and 64 to separate, and thus needle N is released from jaws 50A and 50B of needle holder 40.
- the shaft of needle holder 40 can be rotated in a clockwise direction, by rotating knob 48 or barrel 32, to receive the shank of needle N once again at the position shown by the solid lines in Fig. 6B.
- the shaft of needle holder 40 can then be rotated back in the counter-clockwise direction to pull needle N, and suture material S that is connected to needle N, through tissue T to complete a stitch.
- the movement of the needle is through an arcuate path that extends beyond the diameter of barrel 32 as indicated by the dotted line in Fig.
- needle holder 40 can be rotated in the counterclockwise direction to the other side of tissue T or barrel 32 can be moved away from tissue T (in the direction of arrow A) and needle holder 40 can be rotated in a clockwise direction to the other side of tissue T, as indicated by arrow B.
- needle N can be positioned to permit left-handed operation, i.e. stitching in the opposite direction.
- channel 38a can be used for irrigation or aspiration, can serve as a space for holding the suture material or as a portal for the introduction of other medical instruments such as, forceps, cutting members, endoscopes or ligators. Also, additional channels can be formed for irrigation, aspiration, or the like. Further, the passage through inner member 44 of the needle holder 40 can be used as an operating channel, accessed through proximal aperture 90, because aperture 70 is formed in arm 51 A.
- Needle holder 40 can be modified to suture anatomical tissue with straight or slightly curved suture needles by shaping jaw members 50A and 50B appropriately to receive and hold the needle. Also, jaw members 50A and 50B can be rotatable on arms 51 A and 51 B to accept needle N more smoothly.
- known knotting elements can be used in lieu of traditional knotting techniques during the suturing procedure. Some examples of suitable knotting elements for this purpose are described in pending U.S. applications Serial Nos. 08/366,285, filed December 29, 1994; 08/377,723, filed January 25, 1995; 08/401 ,002, filed March 9, 1995; and 08/585,875, filed January 16, 1996, the disclosures of which are incorporated herein by reference.
- both axial ends of needle N are provided with sharp, tissue penetrating tips, it is possible to penetrate the anatomical tissue at multiple locations in order to form a continuous run of stitches merely manipulating the needle in a "shuttle" manner, i.e. passing the needle through the tissue in alternating directions.
- the suturing instrument permits suturing of anatomical tissue during endoscopic procedures without the need for difficult manipulation of the instrument.
- the needle holder is operable to grasp and release a suture needle so that the suture needle can be driven through anatomical tissue, and can be moved to pull the suture material through the anatomical tissue with a large working span.
- an instrument such as ligator 80 can be inserted from the proximal end of barrel 32 of suture device 30 through an operating channel defined through needle holder 40, through proximal aperture 90, to extend out of aperture 70 at the distal end of needle holder 40 as illustrated by the dotted line in Fig. 1.
- Fig. 8 illustrates ligator 80 removed from barrel 32 for illustrative purposes.
- Ligator 80 consists of tubular member 82 having tapered portion 84 at a distal end and handle 86 at a proximal end. A length of suture material extends through tubular member 82. One end of the suture material is fastened to handle 86.
- the other end of the suture material extends out of an opening formed in tapered portion 84 and is formed into loop L by slipknot 83 formed at an end portion of the suture material and around a portion of suture material near tapered portion 84.
- the opening in tapered portion 84 is large enough to permit unknotted portions of the suture material to pass therethrough but not large enough to permit slip knot 83 to pass therethrough.
- Handle 86 can be separated from tubular member 82 as shown by the dotted line in Fig. 8. Handle 86 can extend from proximal aperture 90 at a proximal end of suturing device 30, as illustrated by the dotted line in Fig. 1. Therefore handle 86 can be manipulated by the surgeon. In particular, handle 86 can be pulled away from tubular member 82 to pull suturing material through slipknot 83 to thereby reduce the size of loop L. This can facilitate knotting of suture material that has been pulled through the tissue by needle holder 40 as is described below.
- a shank of needle N is grasped between jaw members 50A and 50B of needle holder 40.
- a length of suturing material is attached to the shank and a loop is formed on a free end of the suturing material by knotting element 85 as illustrated in Fig. 7A.
- Needle holder 40 is pivoted, by rotating its shaft in the manner disclosed above, to pass needle N through the tissue to be sutured, such as the folded vaginal wall tissue T illustrated in Fig. 7A. Needle holder 40 then releases the shank of needle N and is pivoted in the reverse direction to pass to the other side of folded tissue T where needle holder 40 is operated to grasp the shank of needle N that has passed through tissue T in the manner disclosed above.
- Needle holder 40 is then pivoted to pull needle N entirely through tissue T. Subsequently, needle holder 40 is manipulated to pull needle N through loop L of suture material on the end of ligator 221 to the position illustrated in Fig. 7A (in which the tissue has been moved relative to the instrument for clarity). Needle holder 40 can be movable axially in barrel 32 as disclosed in pending U.S. application Serial No. 08/847,189 entitled "Surgical Instrument with Multiple Rotatably Mounted Offset End Effectors and Method of Using the Same", the disclosure of which is incorporated herein by reference. This facilitates passing needle N through loop L.
- needle holder 40 can be manipulated to pull suture material snugly into tissue T and seat knotting element 83 against one side of tissue T. Subsequently, loop L can be tightened around the suture material on the other side of tissue T by pulling on handle 86. This secures the suture material against the other side of tissue T so that the suture material cannot pass back through tissue T.
- the suture material can then be cut from needle N and ligator 80 by cutting elements 53 formed in the jaws of needle holder 40.
- Fig. 7B illustrates an alternative arrangement in which the suture material connected to the needle extends from siipnot 83 forming loop L. This arrangement is otherwise similar to the arrangement of Fig. 7A and is operated in a similar manner.
- a plurality of ligators 80 can be inserted in a cluster through an operating channel to permit multiple portions of tissue to be sutured, as illustrated in Fig. 11.
- the plural loops of ligators 80 can all extend through a slot formed in sheath 87 that covers and end of a cluster of ligators 80.
- handles 86 for the plural ligators can be disposed in seriatim along a proximal end of the ligator cluster as illustrated in Fig. 9. Each handle 86 can then be separated to manipulate the corresponding loop one at a time.
- Figs. 9 and 10 show a ligator cluster in which the ligators 80 all extend to the distal end of the cluster. Figs.
- 11 and 12 show a ligator cluster in which the ends of the ligators 80 are staggered to permit each loop to extend downward without interfering with the other loops.
- a plurality of ligators can extend from different operating channels
- a lock device can be provided to selectively lock the ligators in position.
- This embodiment can utilize proximal end controls similar to those discussed above with respect to the first preferred embodiment or can include a "pistol-grip" handle at the proximal end thereof similar to that disclosed in pending U.S. application Serial No. 08/758,648, the disclosure of which is incorporated herein by reference.

- Needle holder 40 is disposed within operating channel 38a in barrel 32.
- Needle holder 40 includes outer member 42, inner member 44 disposed in outer member 42, and jaw members 50A and 50B coupled to a distal end of inner member 44.
- Outer member 42 has a bent perpendicular segment disposed perpendicularly or angularly to a main body of the outer member and an offset distal segment extending from the angled segment and disposed parallel to the main body of the outer member 42. Both the bent segment and the distal segment extend out of a distal end of barrel 32.
- An operating channel extends entirely through the outer member 142 including the bent segment and the distal segment and terminates at aperture 70.
- Inner member 44 includes a main body disposed in the main body of outer member 42, a bent perpendicular segment disposed in the bent segment of outer member 42 and a Y-shaped segment 45 disposed in the distal segment of outer member 42.
- a passage extends entirely through the main body of inner member 44 in axial or longitudinal alignment with aperture 70 formed in the angled segment of the outer member 42 such that ligator 80, or another instrument, can pass therethrough.
- the bent segments correspond to the arm or connecting member of the embodiment discussed above.
- Y-shaped segment 45 has outwardly extending portions 47 that are pivotally connected to legs 49A and 49B extending from jaw members 50A and 50B, respectively.
- Legs 49A and 49B are angled inwardly from their respective jaw members to overlap one another in cross-wise fashion. Proximal ends of legs 49A and 49B are pivotally connected to extending portions 47, respectively, at pivots. These pivots also permit extending portions 47 to slide axially along legs 49A and 49B.
- Legs 49A and 49B are pivotally connected to one another, where they overlap, by a pivot. This pivot is fixedly secured to outer member 42 such that the pivot cannot move longitudinally.
- Inner member 44 is slidably disposed in outer member 42 to permit longitudinal movement relative thereto.
- FIG. 15A and 15B A suturing instrument according to a second preferred embodiment is illustrated at 130 in Figs. 15A and 15B.
- This embodiment includes needle driver 140 and is similar to the second preferred embodiment except for the configuration of the bent segments of inner member 144 and outer member 142.
- the bent segments are curved to correspond substantially with the curvature of the circumferential outer surface of barrel 132.
- Jaw members 150A and 150B are moveably mounted on a distal end of outer member 142 to open and close in a manner similar to the jaw members disclosed above in Figs. 13 and 14. Jaw members 150A and 150B can be similar to the jaw members illustrated in Fig. 5 also.
- arm 151 can easily be confined within the diametrical dimension of barrel 132 during insertion.
- jaws 150A and 150B can be moved, by rotating the shaft defined by inner member 144 and outer member 142, to cause jaw members 150A and 150B to be moved through a path that is outside of the diametrical dimension of barrel 32. Rotation of the shaft can be accomplished in a manner similar to the first embodiment described above.
- Figure 16 illustrates an alternative needle driver 40 in which arm member 51 A is mounted on inner member 44 and arm member 51 B is mounted on outer member 42. Jaws 50A and 50B can be opened by rotating inner member 44 and outer member 42 relative to one another. Rotating outer member 42 and inner member 44 in concert will permit a needle to be advanced through an arcuate path. Also, longitudinal and transverse grooves are formed in the jaws to facilitate grasping the needle.
- handles 62 and 64 can be coupled to needle driver 40 in a manner which causes the desired rotation of the shaft of needle driver apparatus 40 and the opening and closing operation of the jaws necessary for a single stitch, or multiple stitches, to be effected merely by squeezing and releasing handles 62 and 64 once or multiple times.
- the mechanism coupling handles 62 and 64 to needle driver apparatus 40 can be designed to accomplish any of the stitching functions disclosed above or any other appropriate motion. Such an automatic mechanism facilitates suturing by minimizing fatigue on the surgeon and reducing the possibility of operational errors.
- FIG. 17-20 An example of an automatic mechanism is illustrated in Figs. 17-20.
- handle 64 is fixed to housing 79 and handle 62 is rotatably disposed on shaft 160.
- Beveled gear 162 is also disposed on shaft 160 and is engaged with beveled gear 164 disposed on outer member 42. Accordingly, compression of handle 62 toward handle 64 causes outer member 42 to rotate.
- Inner member 44 is constructed to rotate with outer member 42.
- projection 170 extends from inner member 44 through slots formed in outer member 42 and beveled gear 164. A free end of projection 170 slides along cam groove 168 formed in cylindrical member 166. Therefore, as inner member 44 rotates, inner member 44 is moved axially relative to outer member 42, causing jaws of needle holder 40 open or close.
- a needle is grasped in the jaws of needle holder 40 in the position illustrated in Fig. 17.
- Handle 62 is squeezed toward handle 64, by the surgeon, causing needle holder 40 to turn clockwise, as viewed from the distal end of the suturing instrument.
- the jaws are opened by projection 170 as it follows cam groove 168.
- handle 64 can be released causing needle holder 40 to rotate counter-clockwise, as viewed from the distal end as projection 170 continues in the same direction along cam groove 168 to maintain the open position of the jaws.
- the jaws of needle holder 40 can now be positioned around the tip of the needle that has penetrated the tissue. Compressing the handles again will close the jaw and pull the needle through the tissue.
- cam groove 168 can be shaped in various ways to provide the desired opening and closing of the jaws.
- the jaw members can be configured to hold any type of needle including, but not limited to, straight and curved needles.
- One or more lengths of suture material can be attached to each suture needle at any desirable location along the body or tip of the needle including, but not limited to, the proximal end of the needle, intermediate or medial portions of the needle body, or locations adjacent the tip of the needle.
- the suturing instrument according to the present invention can be used with any type of standard suturing needle including, but not limited to, needles having sharp or blunt tissue penetrating tips, and needles having tissue penetrating tips at opposite axial ends of a needle body.
- the jaw members and other components can have any suitable configuration for cooperatively grasping needles to suture anatomical tissue including, but not limited to, configurations wherein the jaw members pivot, slide or otherwise move relative to one another to capture and release a needle.
- the jaw members can, for example, be of straight, curved or angled configuration and can be provided with ribs, grooves, slots and/or holes along grasping surfaces to assure a positive grip.
- the jaw members can also carry cutting members, such as slots with sharp edges or protruding blades, and can have opposed arcuate or concave portions for clamping tubular objects, such as organs, without compressing the objects.
- the mechanisms for moving the driver apparatus is merely exemplary of the types of mechanisms that can be used to perform this function and other mechanisms can be used.
- the particular length and curvature of the suture needles shown and described herein as well as any angular displacements of the needle driver apparatus shown and described herein are merely exemplary, and it will be appreciated that other needle lengths and angular displacements can be used.
- the needle driver apparatus can be movable in the proximal and distal directions.
- the needle holder can be used as forceps, to grasp the tissue, before or after suturing or can include a clip applicator. Therefore the invention can be used for pickup and cutting, pickup and clipping, pickup and suturing, or lysis of adhesion procedures.
- a forceps device can be inserted through the operating channel formed in the shaft of one of the needle holders or another operating channel.
- blade members on the jaws can be used for cutting tissue.
- Electrical connector 91 can serve to couple the jaws or any other instrument to an electrical power source to permit unipolar or bipolar cauterization.
- the jaws can be placed on either side of tissue to manipulate the tissue without grasping it by pushing the tissue.
- the components of the suturing instrument of the present invention can be made of any suitable, medical grade materials to permit sterilization for reuse or disposal for single patient use.
- the components can be made of multiple parts of various configurations and materials to reduce cost.
- the invention can have various valves, stop-cocks and seals therein to control the flow of fluid and medical devices through the suturing instrument.
