Abstract

A surgical stapling assembly comprising a firing member, an end effector, a closure member, and a shaft including an attachment interface is disclosed. The surgical stapling assembly is configured to be attached to a surgical instrument interface by way of the attachment interface. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples configured to be ejected by the firing member. The second jaw is movable relative to the first jaw between an open position, a fully-clamped position, and a collapsed position. The end effector further comprises an interconnection between the first jaw and the second jaw defining a rotational axis about which the second iaw is movable relative to the first iaw. The rotational axis is shiftable toward and away from the first iaw as the second iaw is moved between the open position, the fully-clamped position, and the collapsed position.
