1. A surgical stapling device comprising:
- a handle portion;
a body portion extending distally from the handle portion;
a head portion including an anvil and a cartridge, the cartridge being movable in relation to the anvil from an open position to a closed position;
an approximation mechanism operatively connected to the cartridge and being actuable to move the cartridge from the open position to the closed position;
an alignment pin assembly including a pusher operatively associated with the approximation mechanism, the pusher being movable in response to actuation of the approximation mechanism; and
a manual engagement member located remotely of the head portion and being operatively associated with the alignment pin assembly, the manual engagement member being movable to manually move the pusher from a retracted position to an advanced 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.
