Abstract

An apparatus that includes a body, a shaft, and an end effector. The end effector includes a first jaw, a second jaw, and a tip. The second jaw includes an anvil. At least one of the first jaw or the second jaw is configured to move relative to the other of the first jaw or the second jaw between an open position and a closed position. The tip is connected with the anvil. The tip includes a deformable member. The tip is movable relative to the anvil between first and second discrete positions using the deformable member. The tip remains in the first discrete position located closer toward the cartridge until the deformable member is acted upon by an external input force. The tip remains in the second discrete position that is located further from the cartridge until the deformable member is acted upon by the external input force.
