摘要：
A surgical end effector for use with a surgical instrument that includes an elongate shaft assembly that includes a rotary output drive shaft is disclosed. An elongate channel is attached to the elongate shaft assembly. An anvil frame that comprises a proximal end and a distal end is selectively movable between open and closed positions relative to the elongate channel. An anvil concentric drive member is rotatably supported by the anvil frame and is configured to receive rotary drive motions from the rotary output drive shaft of the surgical instrument when the anvil frame is in the closed position. A firing member is in driving engagement with the anvil concentric drive member for linear travel through the end effector.
