A surgical stapling system comprising a housing, an end effector, a replaceable staple cartridge, a driver element, a motor-powered firing element, a remote user-controlled console, and a retraction assembly is disclosed. The end effector comprises a first jaw and a second jaw. The first jaw is rotatable relative to the second jaw into a closed position. The driver element is translatable distally in response to a firing motion. The motor-powered firing element is advanceable from a proximal position to a fired position to apply the firing motion to the driver element. The motor-powered firing element is retractable from the fired position toward the proximal position. The remote user- controlled console is capable of controlling the actuation of the motor-powered firing element. The remote user-controlled console comprises apparatus for sensing the closure of the first jaw and apparatus for sensing the advancement and retraction of the motor-powered firing element.
