Abstract
A surgical instrument is presented that may include a handle assembly, a shaft assembly, an end effector and an articulation joint coupled to the shaft assembly and the end effector. The surgical instrument also may include an articulation control mechanism configured to: control movement of the articulation joint between a first and second maximum articulation angle; determine that the articulation joint has articulated to the first maximum articulation angle; provide a first indication that the articulation joint has articulated to the first maximum articulation angle; determine that the articulation joint has articulated to the second maximum articulation angle; and provide a second indication that the articulation joint has articulated to the second maximum articulation angle.
