Stapling device with selectively advanceable alignment pin

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 to a deactivated position, wherein in the activated position, 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 and in the deactivated position the alignment pin assembly is uncoupled from the approximation mechanism, and wherein movement of the member from the activated position to the deactivated position withdraws the member from within the housing.
