Abstract

A surgical instrument is disclosed including an end effector, a firing drive, and a mechanical closure system. The end effector includes a first jaw including a proximal end and a distal end, a second jaw rotatable relative to the first jaw between an open position and a closed position, a staple cartridge including staples removably stored therein, and a cutting member movable toward the distal end during a staple firing stroke. The firing drive includes a drive shaft operable to move the cutting member through the staple firing stroke, a gear drive train operably coupled to the drive shaft, an electric motor configured to actuate the gear drive train, and a firing trigger actuatable to actuate the electric motor. The mechanical closure system includes a closure member movable distally to close the second jaw during a closure stroke and a closure trigger rotatable between an unactuated position and an actuated position to advance the closure member through the closure stroke. The firing trigger pivots from a recessed position to an exposed user-accessible position when the closure trigger is placed in the actuated position.
