Abstract
A surgical system comprising an elongate shaft and an end effector is disclosed herein. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples removably stored therein, wherein the first jaw is movable relative to the second jaw. The surgical system further comprises a first rotatable drive system configured to close the first jaw and a second rotatable drive system. The second rotatable drive system comprises a drive screw, a drive member movable between a proximal position and a distal position during a staple firing stroke, and a sled configured to eject the staples from the staple cartridge during the staple firing stroke. The sled is not pulled proximally by the drive member when the drive member is retracted. The end effector, the drive screw, and the sled comprise a replaceable assembly.
