A surgical instrument comprising a handle, an elongate shaft, an end effector, an articulation joint, an articulation knob, an articulation member, and an articulation lock is disclosed. The end effector is rotatably coupled to the elongate shaft by the articulation joint. The articulation knob is rotatable between an un-rotated position and rotated positions. The articulation lock comprises a lock member configured to move between a locked position where the lock member is engaged with a detent of the end effector and an unlocked position where the lock member is disengaged from the end effector. The lock member is movable between the locked position and the unlocked position by the articulation knob. The articulation member is moved from a proximal position toward a distal position to articulate the end effector when the articulation knob is moved from the un-rotated position toward a rotated position. |
