Abstract
A surgical fastening and cutting assembly having a housing defines a passage and a pusher, with a cam surface, slides in the passage. An arm couples to the housing and an anvil base is located on the arm. A body slides on the arm between the housing and the base. The body defines a bore and a staple passage having a staple therein. A cam follower extends from the cartridge body to the housing. In an open position, tissue can be placed between the anvil base and the body. In an intermediate position, the cam surface of the pusher can move the cam follower into a locked position and, thereby, the tissue can be clamped. In a fastened and cut position, the pusher can move such that the staple can be been driven and formed in the tissue and a knife, coupled to the pusher, can cut the tissue.
