Surgical stapling device
First Claim
1. A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue, the surgical instrument comprising:
- a frame having a proximal end and a distal end, with a handle positioned at the proximal end and being shaped and dimensioned for supporting a cartridge assembly and an anvil assembly at the distal end, the cartridge assembly and anvil assembly being relatively movable by actuation of an approximation mechanism;
a firing mechanism associated with the cartridge assembly for selective actuation of the surgical fasteners; and
an alignment pin for enclosing tissue between the anvil assembly and the cartridge assembly, the alignment pin is moved by actuation of the approximation mechanism from an open position to a closed position; and
a manual actuator associated with the alignment pin for moving the alignment pin from the open position to the closed position prior to actuation of the approximation mechanism.

Abstract
A surgical stapling device for applying an array of surgical staples to tissue is provided. The stapling device includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly. A single trigger is operable to effect approximation and firing of the device. The device also includes an alignment pin assembly which can be selectively manually or automatically advanced. The anvil assembly includes a stiffener plate which allows the device to have a reduced head portion profile.
