    摘要： A surgical stapling or fastening instrument for applying surgical fasteners to tissue having an adjustable closure mechanism to linearly approximate the distance between the jaw members of the instrument. The adjustable closure mechanism consists of an advancing mechanism and a retaining mechanism which is actuable to urge the jaw members towards each other. A coupling arrangement is also provided which permits firing of the staples or fasteners only when the jaw members are approximated a predetermined distance from each other.

    摘要： The end-to-end anastomosis apparatus is provided with a mounting means which can receive a trocar for making holes in tissue and, subsequently, an anvil shaft for the mounting of an anvil assembly for stapling purposes. The anvil shaft is provided with splines which cooperate with splines on a shell liner within the housing of the apparatus to align the buckets on the anvil assembly with the staples in a cartridge secured in the apparatus. In addition, the anvil assembly is provided with a spring for locking of the anvil housing on the anvil shaft.

    摘要： The fascia clip is of two-piece construction having an elongated base and a flexible strap. The base is sized to bridge over an incision in fascia tissue and has openings at opposite ends. The strap has a pointed distal end for passage through the opening at the proximal end of the base so as to pierce through the fascia tissue. After being directed under the incision, the strap can again pierce the tissue to pass through the opening at the distal end of the base in order to be gripped therein. The strap has an enlarged head at the proximal end to prevent complete passage through the opening at the proximal end of the base. In one embodiment, resilient teeth are used at the distal end of the strap to engage with a web about the opening at the distal end of the base. In another embodiment, a resilient tab on the enlarged head of the base engages in an opening in the distal end of the strap.

    摘要： An endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating fastener applying assembly associated with a distal end of the elongated portion. The fastener applying assembly includes a base portion, a staple cartridge housing, and an anvil member which has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge housing. A first mechanism is provided for effectuating the rotation of the fastener applying assembly about an axis defined by the body portion, a second mechanism is provided for effectuating the articulation of the fastener applying assembly, and a third mechanism is provided for independently rotating the cartridge housing and anvil member relative to a longitudinal axis defined by the base position to increase the range of operability of the apparatus.

    摘要： Surgical instrumentation and methods for performing a bypass procedure in a digestive system incorporate laparoscopic techniques to minimize surgical trauma to the patient. The instrumentation includes an outer guide member dimensioned for insertion and passage through an esophagus of a patient and defining an opening therein extending at least along a portion of the length of the outer guide member, an elongate anvil delivery member at least partially disposed within the opening of the outer guide member and being adapted for longitudinal movement within the outer guide member between an initial position and an actuated position and an anvil operatively engageable with the delivery member. The anvil includes an anvil rod defining a longitudinal axis and an anvil head connected to the anvil rod. The anvil head is at least partially disposed within the opening of the outer guide member when in the initial position of the delivery member and is fully exposed from the distal end of the outer guide member upon movement of the delivery member to the actuated position.

    摘要： A surgical stapler for securing a prosthetic heart valve within a patient is disclosed and generally includes a first cylindrical portion for carrying a staple assembly on a distal end thereof, a second cylindrical portion positioned concentrically about the first cylindrical portion and having a camming arm on a distal end thereof and a third cylindrical portion positioned concentrically about the second cylindrical portion and having an anvil flange on a distal end thereof, the camming arm configured to cam the staple assembly radially outward and drive the staple assembly distally such that a first leg of the staple assembly penetrates a cuff of the prosthetic heart valve and a second leg of the staple assembly pierces a portion of heart tissue surrounding the prosthetic heart valve to secure the valve. A method of installing a heart valve within a patient utilizing the surgical stapler is also disclosed.
