A stapling device comprising: a handle assembly including a housing defining a stationary handle and a trigger, the trigger being pivotably supported on the housing; a frame extending distally from the housing; a tool assembly supported on the frame, the tool assembly including an anvil and a cartridge assembly, the cartridge assembly including an alignment pin and being movable along the frame assembly between an open position and clamped position; an alignment pin assembly including an alignment pin pusher, the alignment pin pusher including an abutment positioned to engage the alignment pin in the cartridge assembly, the alignment pin pusher being movable between a retracted position and an advanced position to move the alignment pin from a position within the cartridge assembly to a position extending from the cartridge assembly; an approximation mechanism supporting the cartridge assembly, the approximation mechanism being coupled to the handle assembly and being movable from a retracted position to an advanced position in response to actuation of the handle assembly to move the cartridge assembly from the open position to the clamped position; and a linkage assembly including a member extending through the housing that is accessible to a clinician, the member being movable from an activated position in which the linkage assembly couples the alignment pin assembly to the approximation mechanism such that movement of the approximation mechanism causes movement of the alignment pin pusher to a deactivated position in which the alignment pin assembly is uncoupled from the approximation mechanism, the linkage assembly includes a bell crank assembly having a bell crank and the member, characterised in that the member includes a bell crank pin, wherein the bell crank defines at least one opening that receives the bell crank pin when the bell crank pin is in the activated position, and wherein the bell crank pin is pivotably connected to the frame and the bell crank pin, in the activated position, is coupled to the approximation mechanism. a handle assembly including a housing defining a stationary handle and a trigger, the trigger being pivotably supported on the housing; a frame extending distally from the housing; a tool assembly supported on the frame, the tool assembly including an anvil and a cartridge assembly, the cartridge assembly including an alignment pin and being movable along the frame assembly between an open position and clamped position; an alignment pin assembly including an alignment pin pusher, the alignment pin pusher including an abutment positioned to engage the alignment pin in the cartridge assembly, the alignment pin pusher being movable between a retracted position and an advanced position to move the alignment pin from a position within the cartridge assembly to a position extending from the cartridge assembly; an approximation mechanism supporting the cartridge assembly, the approximation mechanism being coupled to the handle assembly and being movable from a retracted position to an advanced position in response to actuation of the handle assembly to move the cartridge assembly from the open position to the clamped position; and a linkage assembly including a member extending through the housing that is accessible to a clinician, the member being movable from an activated position in which the linkage assembly couples the alignment pin assembly to the approximation mechanism such that movement of the approximation mechanism causes movement of the alignment pin pusher to a deactivated position in which the alignment pin assembly is uncoupled from the approximation mechanism, the linkage assembly includes a bell crank assembly having a bell crank and the member, characterised in that the member includes a bell crank pin, wherein the bell crank defines at least one opening that receives the bell crank pin when the bell crank pin is in the activated position, and wherein the bell crank pin is pivotably connected to the frame and the bell crank pin, in the activated position, is coupled to the approximation mechanism.
