    摘要： A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue includes a cartridge module having a cartridge housing containing a plurality of surgical fasteners and a knife. The cartridge module includes a driver disposed to push surgical fasteners out of the cartridge housing. The instrument also includes a firing mechanism associated with the cartridge housing for ejecting the surgical fasteners and the knife from the cartridge housing. The knife includes a detent disposed to contact a mating detent of the cartridge module during longitudinal travel of the knife thereby preventing undesired forward and rearward motion of the knife. The driver includes a detent disposed to contact at least one mating detent formed on the cartridge module.

    摘要： A surgical instrument is adapted for stapling tissue in a highly controlled manner. The surgical instrument includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end. The end effector is shaped and dimensioned for selectively receiving a cartridge module containing a plurality of surgical fasteners. A firing mechanism is associated with the end effector and the cartridge module for selective actuation of the surgical fasteners. The cartridge module includes a cartridge housing in which the surgical fasteners are housed and an anvil shaped and dimensioned for engagement with the surgical fasteners to facilitate stapling. The cartridge housing and anvil are relatively movable between a first spaced apart position and a second position in close approximation with one another. A retainer is removeably positioned between the anvil and the cartridge housing to prevent undesired movement of the cartridge housing toward the anvil.

    摘要： A surgical instrument for cutting and applying a plurality of surgical fasteners in the same direction to body tissue includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end. The end effector is shaped and dimensioned for supporting a cartridge housing and an anvil. The cartridge housing and anvil are relatively movable between a first spaced apart position and a second position in close approximation with one another, and the cartridge housing includes a knife structure adapted for cutting tissue by moving between the cartridge housing and the anvil. The instrument also includes a firing mechanism associated with the end effector and the cartridge housing for selective actuation of the knife structure and surgical fasteners for movement in the same direction. The knife structure includes a rearwardly facing coupling member shaped and dimensioned for engaging a distal end of the firing mechanism as the cartridge housing is loaded into the end effector of the surgical instrument.
