  • Cartridge retainer for a curved cutter stapler
    Patent number: 7147140
    Abstract: 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.
