Abstract
A surgical instrument comprises an elongate shaft having a proximal end, a distal end, and an articulating portion. An end effector is on the distal end and an actuator is on the proximal end. A rod is in the shaft having a proximal end with a cam follower, a distal end operably connected to the articulation portion, and a longitudinal axis extending between the proximal and distal ends. A disk is in the actuator rotatable in response to user input in a plane substantially parallel to the longitudinal axis of the rod. The disk has a cam slot receiving the cam follower such that rotation of the disk moves the rod longitudinally to articulate the elongate shaft at the articulation portion.
