A surgical stapling device comprising:
a handle portion including a trigger;
a body portion extending distally from the handle portion;
a head portion including an anvil and a cartridge, the anvil and cartridge being movable in relation to each other from an open position to a closed position in which the anvil and cartridge are in close cooperative alignment;
an approximation mechanism operatively connected to the head portion and being actuable to move the anvil and cartridge between the open and closed positions;
an alignment pin assembly including a pusher operatively associated the approximation mechanism, the pusher being movable in response to actuation of the approximation mechanism between retracted and advanced positions; and
an engagement member operatively associated with the alignment pin assembly and being movable to manually advance the pusher from the retracted position to the advanced position prior to actuation of the approximation mechanism. |
