    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： A device for driving surgical fasteners into tissue such as the menisci of the knee. The device essentially consists of a tubular housing member through which a piston shaft passes. The piston shaft extends at a first end and terminates in a gripping knob which facilitates retraction of the piston from the housing, and contacts a fastening member at a discharge end to drive the fastener from the device. A pivotable latching member engages the gripping knob when the piston arrangement is retracted against the force of the spring, and pivots to release the piston arrangement to fire the fastener.

    摘要： A detachable anvil rod for use with an apparatus for circular fastening of hollow organs is provided. An elongated rod member has a proximal end portion, a distal end portion and an irregular surface portion intermediate the proximal and distal end portions. The irregular surface portion includes a plurality of grooves which define a plurality of raised ridges. The ridges are adapted to engage grasping surfaces of a grasping tool so as to minimize potential of slippage, thus enhancing the maneuvering procedure of the anvil rod about the operative site. The anvil rod also includes a narrowly configured mounting portion which enables the rod to be applied to and mounted within the distal end of the stapling apparatus from a variety of angular positions. An apparatus which incorporates the improved detachable anvil rod is also described.
