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.

Abstract: A surgical stapling assembly comprising a staple cartridge carrier, an anvil, an outer surface, a closure member, a staple cartridge, and a firing system is disclosed. The anvil is rotatable between a first position and a second position. The closure member is slideable along the outer surface to hold the anvil in the second position. The closure member comprises a clearance opening. The staple cartridge is positioned within the staple cartridge carrier. The staple cartridge comprises staples removably stored therein. The staple cartridge and the anvil define a tissue gap therebetween when the anvil is in the second position. The clearance opening is aligned with the tissue gap when the anvil is in the second position. The firing system is configured to eject the staples from the staple cartridge during a staple firing stroke. The firing system engages the staple cartridge carrier and the anvil during the staple firing stroke.

Abstract: A disposable loading unit for use with a surgical stapling instrument is disclosed. The disposable loading unit comprises a cutting member, an anvil, and a first replaceable stapling jaw assembly. The first replaceable stapling jaw assembly comprises a first cartridge body and first staples. The disposable loading unit further comprises a second replaceable stapling jaw assembly comprising a second cartridge body and second staples. The disposable loading unit further comprises a lockout that prevents the first replaceable stapling jaw assembly from being fired after the first replaceable stapling jaw assembly has been at least partially fired. The surgical stapling instrument and the disposable loading unit are configured to deploy the second staples from the second replaceable stapling jaw assembly with which the first replaceable stapling jaw assembly is replaced.

Abstract: A surgical stapling assembly that comprises an end effector, a staple cartridge, a plurality of staples, a shaft assembly, a housing, a rotary motion actuator, a first actuation system configured to cause the end effector to perform a first function, and a second actuation system configured to cause the end effector to perform a second function is disclosed. The surgical stapling assembly further comprises a selector arrangement transitionable between a first orientation and a second orientation. The rotary motion actuator is configured to operably interface with the first actuation system in the first orientation to cause the end effector to perform the first function. The rotary motion actuator is configured to operably interface with the second actuation system to cause the end effector to perform the second function in the second orientation.
