Abstract

A surgical stapling apparatus, including a frame, an endoscopic portion, a clamp handle, a firing handle, a tool assembly and a drive beam is disclosed. The endoscopic portion extends distally from the frame. The clamp handle is disposed on the frame and in mechanical cooperation with a drive member. The firing handle is disposed on the frame and in mechanical cooperation with at least one firing rod. The tool assembly includes an anvil, a cartridge assembly and a camming surface and is supported adjacent a distal end of the endoscopic portion. Actuation of the clamp handle moves the drive beam into engagement with the camming surface. Actuation of the firing handle moves the firing rod through an opening in the drive beam to eject surgical fasteners from the cartridge assembly.
