  • Retaining pin lever advancement mechanism for a curved cutter stapler
    Patent number: 6988650
    Abstract: A surgical instrument is adapted for applying a plurality of surgical fasteners to body tissue. 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 supporting a cartridge housing and an anvil, the cartridge housing and anvil being relatively movable by actuation of a closure mechanism. The surgical instrument further includes a firing mechanism associated with the end effector and the cartridge housing for selective actuation of the surgical fasteners features. The surgical instrument also includes a retaining pin for enclosing tissue between the anvil and the cartridge housing. The retaining pin is moved by actuation of the closure mechanism from an open first position to a closed second position.
