Surgical System

A surgical system comprising a surgical instrument, a motorized system, and a control system is disclosed. The surgical instrument comprises an end effector comprising a first jaw and a second jaw movable relative to the first jaw. The surgical instrument further comprises a threaded drive shaft, a firing member drivable by the threaded drive shaft, and a closure system configured to move the second jaw. The motorized system is configured to drive the threaded drive shaft and the closure system. The control system comprises a closure circuit configured to actuate the motorized system to move the second jaw toward a closed position, a firing circuit configured to actuate the motorized system to move the firing member toward a fired position, and an input interface configured to receive inputs from a user. The firing circuit is prevented from being actuated until the second jaw has been placed in the closed position.
