Abstract
A stapling system comprising an end effector, a staple cartridge, a rigid shaft, an articulation joint, an articulation system, a clamping member, and a firing system comprising a sled movable within the staple cartridge to eject staples from the staple cartridge during a staple firing stroke, an electric motor, and a firing actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an unclamped position and a clamped position. The clamping member is configured to rotate the second iaw into the clamped position. The stapling system further comprises a system responsive to the clamping of the second iaw which enables the staple firing stroke to be performed after the second jaw has been rotated into the clamped position, and a system configured to maintain an orientation of the end effector about the articulation joint during the staple firing stroke.
