Abstract: A surgical instrument comprising a handle assembly, an elongated shaft, an end effector, a rotation mechanism, and an articulation mechanism is disclosed. The rotation mechanism is disposed in mechanical cooperation with the handle assembly and effects rotation of the end effector about the second longitudinal axis. The articulation mechanism is disposed in mechanical cooperation with the handle assembly and effects movement of the end effector from a first position where the first longitudinal axis is substantially aligned with the second longitudinal axis to a second position where the second longitudinal axis is displaced from the first longitudinal axis. The articulation mechanism comprises a first articulation control disposed in mechanical cooperation with the handle assembly, a first cable and a second cable. Actuation of the first articulation control in a first direction causes the first cable to move distally and causes the second cable to move proximally.
