    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 actuator mechanism permits adjustment of the anvil gap to produce a desired staple height 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: An electrosurgical instrument according to the present invention includes a handle, an elongated tube, an end effector, a pair of wireform conductors extending through the elongated tube from the handle to the end effector and a working tool such as, for example, a knife blade. The working tool being connected to the handle through a push bar which passes through the elongated tube. In an electrosurgical instrument according to the present invention, the push bar is positioned between the wireform conductors and is axially moveable with respect to the wireform conductors. In addition, in an electrosurgical instrument according to the present invention, the handle includes a coupling element to allow the wireform conductors and push bar to rotate with respect to the handle and to allow the push bar to move axially with respect to the wireform conductors and the handle.

    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.
