KNIFE RETRACTION ARM FOR A CURVED CUTTER STAPLER |
摘要 |
A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue is provided, comprising a frame having a proximal handle and a distal end effector that is shaped and dimensioned for supporting a cartridge housing and an anvil which are movable relative to one another. The cartridge housing includes a knife structure adapted for cutting tissue by moving between the cartridge housing and the anvil. A firing mechanism is associated with the end effector and the cartridge housing for selective actuation. The knife structure includes a knife and a knife holder, and the knife holder is located on a proximal end of the knife opposite to a cutting edge of the knife. The firing mechanism includes a knife retraction hook having a hook that faces upward to receive the knife holder as the cartridge housing is loaded into the end effector of the linear surgical stapler. |
