摘要： A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The aotuator mechanism permits adjustment of the anvil gap to produce a desired staple heiqht and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.

摘要： In accordance with the present invention there is provided a method for suturing tissue using a needle holder device, The device includes a handle for holding it, the handle has distal and proximal ends. The device also has right and left arms extending distally from the handle. The arms of the device have proximal ends attached to the handle and distal ends having grippers attached thereto for gripping and releasing a needle. The device includes at least one mechanism for moving the distal ends of the arms closely adjacent to one another and for passing the needle from one gripper to the other and thereafter for moving the distal ends of the arms further apart from one another. The right gripper is holding a needle having a suture attached thereto. The method first involves moving the distal ends of the arms apart from one another and manually inserting the needle into the tissue and back out again. Thereafter, the method involves actuating the mechanism so as to move the arms closely adjacent one another so that the left gripper holds the needle, the right gripper releases the needle. Then the method involves moving the distal ends of the arms further apart from one another. Lastly, the method involves removing the needle from the tissue.

摘要： A multiple-load cartridge assembly for use with a linear surgical stapling instrument of the type which, when actuated, simultaneously implants at least one row of staples in the tissue of a patient and forms or clinches the staples of the row against the instrument anvil. The cartridge assembly comprises a cartridge having a row of staple-containing forming pockets and a driver having a plurality of blades equal in number to the number of forming pockets and configured to drive the staples from the forming pockets through the tissue to be sutured and against the instrument anvil to be clinched, when the surgical stapling instrument is actuated. The cartridge has at least one row of storage pockets, equal in number to the forming pockets, and each containing at least one staple. An indexing mechanism is provided to shift the at least one staple in each storage pocket to the line of action between the driver and the anvil after the first actuation of the surgical stapling instrument, for at least another actuation of the surgical stapling instrument. A safety interlock within the cartridge assembly assures correct sequential operation of the cartridge assembly and prevents jamming thereof. An indicator visually shows the number of the load of staples ready to be implanted and formed.

摘要： A mechanism which is capable of anastomosis of two lumens by an absorbable fastener. The fastener is made from two washer-like plates. One such plate has holes to receive latching prongs protruding from the other plate. Fastening is done through a single linear motion that causes the prongs to pierce the tissue, latches the prongs into a receiver and causes a knife blade to cut through excess fastener material and tissue. The ease of removal, by pulling the mechanism thorugh the formed anastomosis, is greatly enhanced. The system can be used such that the plates can be placed in any configuration to properly anastomose tissue.

摘要： A transanal inserter is disclosed which facilitates the atraumatic insertion of intra-anal surgical devices through the anus. The inserter has a tubular portion, a prolate distal end and a proximal end having a flange associated therewith. The prolate end is formed from a plurality of petal-shaped segments which deflect outward as an intra-anal surgical device is urged therethrough, into the colon or intestine. The flange formed at the proximal end of the inserter retains the inserter in place and prevents over insertion of the inserter beyond the anus. The inserter can be fabricated in varying lengths to accommodate surgical requirements. The inserter is fabricated from a plastic material with sufficient pliability to provide for deflection of the segments, while maintaining sufficient rigidity to prevent collapse of the inserter during insertion and use.

摘要： A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end of the shield is hemispheric in profile and contains slides within cutting tip. The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue. In other embodiments, positive mechanical means effect shielding.

摘要： A device useful in minimally-invasive procedures involving the visualization, dissection and/or harvesting of vessels in the body includes a shaft having a handle mounted on one end and a dissecting tip on the other end. The dissecting tip optionally includes a light source for directing light transverse of the tip and structures to retain the tip in position adjacent the vessel as the tip is advanced along the vessel. Also disclosed are associated methods for transilluminating a vessel, dissecting the vessel from surrounding tissue, and transecting the vessel and side branches and removing the vessel from the body.
