    摘要： A surgical instrument system comprising an end effector, a shaft, a closure drive, a closure member, and a motor-powered firing drive is disclosed. The end effector comprises an elongate channel, a staple cartridge, a clamping member, and a firing member. The staple cartridge comprises a plurality of staples and a plurality of staple drivers. The clamping member is pivotably connected to the elongate channel and movable between an open position and a clamped position during a clamping motion. The firing member is movable within the elongate channel to engage the staple drivers and deploy the staples from the staple cartridge. The closure member is operably connected to the closure drive and is configured to translate in a proximal direction to pivot the clamping member to the clamped position. The motor-powered firing drive is operably connected to the firing member. The closure drive and the firing drive are independently actuatable.

    摘要： A surgical instrument comprising a rotary motion generator, a shifting assembly, a rotatable shaft, an end effector, and a firing member is disclosed. The shifting assembly comprises a first output, a second output, a switch, and a biasing mechanism. The first output and the second output are selectively drivable by the rotary motion generator. The switch is configured to switch between the selective drivability of the first and second outputs. The biasing mechanism is configured to motivate and maintain an operative meshment between the rotary motion generator and one of the first output and the second output. The end effector comprises a first jaw and a second jaw. The first jaw is moveable relative to the second jaw during a closing motion. The firing member is moveable relative to the end effector during a firing motion. The closing motion is separate and distinct from the firing motion.
