The end effector includes a housing having a base portion and a jaw portion, an anvil assembly supported on the jaw portion, and a cartridge assembly releasably supported on the base portion. A tissue guide member is operably secured relative to the cartridge assembly to facilitate alignment of the cartridge assembly through a firing stroke.

A surgical stapling device includes an alignment pin pusher, an approximation assembly, and a linkage assembly. The linkage assembly includes a bell crank assembly including a bell crank and a bell crank pin. The bell crank pin is movable from an activated position to a deactivated position. In the activated position, the bell crank pin couples the alignment pin pusher to the approximation mechanism such that movement of the approximation mechanism causes movement of the alignment pin pusher from a retracted position to an advanced position. In the deactivated position, the bell crank pin is moved to a position to uncouple alignment pin assembly from the approximation mechanism.
