摘要： A surgical stapling instrument comprising an elongate shaft assembly that defines a shaft axis and includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical end effector includes a cartridge support member that is configured to operably support a surgical staple cartridge therein. The surgical instrument further includes a longitudinally movable firing beam that extends through the articulation joint and is selectively axially movable from a starting position to an ending position within the surgical end effector. A firing beam locking assembly comprising a biasing member is operably supported on the articulation joint and is configured to apply a biasing motion to the firing beam to bias the firing beam into a locked position wherein the firing beam is prevented from moving from the starting to the ending position unless an unfired surgical staple cartridge is operably supported in the cartridge support member.

摘要： A surgical instrument comprising a surgical end effector that comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between an open position and closed positions. The surgical instrument further comprises a closure member that is axially movable in response to closing and opening motions. The closure member comprises at least one opening cam that protrudes therefrom to movably engage a corresponding cam surface on the second jaw such that upon application of the opening motion, the at least one opening cam movably engages the corresponding cam surface to move the second jaw to an open position, even when the jaws are under a load.

摘要： A surgical stapling instrument comprising an elongate shaft assembly that that defines a shaft axis and includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical instrument further includes a rotary articulation member that is supported for rotation travel about a rotary axis that is transverse to the shaft axis. A first distal articulation driver assembly and a second distal articulation driver assembly operably interface with the surgical end effector and the rotary articulation member such that rotation of the rotary articulation member causes the first and second distal articulation drivers to articulate the surgical end effector relative to the shaft axis.
