Abstract
A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue is provided, comprising a frame with a proximal handle and a distal end effector.
The end effector 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 adapted for cutting tissue by moving between the cartridge housing and the anvil. The instrument also comprises a firing mechanism associated with the end effector and the cartridge housing for selective actuation and a tissue retention feature associated with the cartridge housing and anvil, the tissue retention including an upper pin and a lower pin maintaining tissue within the end effector during treatment, wherein the upper and lower pins respectively include slots associated with the knife for guiding it between the cartridge housing and the anvil.
