    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.

    Abstract: A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. These lockout bypass features may operate to permit longitudinal translation of the knife member once or multiple times. The end effector may comprise features configured to ensure proper alignment of the anvil relative to the staple cartridge.
