Claim 14:
15. A surgical instrument, comprising:
(a) an end effector, comprising:
(i) an ultrasonic blade, and
(ii) a clamp arm configured to move relative to the ultrasonic blade between an open position and a closed position;

(b) an articulation section located proximally relative to the end effector, wherein the articulation section is configured to deflect the end effector between a non-articulated configuration and an articulated configuration;
(c) a distal shaft portion extending distally from the articulation section along an axis;
(d) a clamp arm closure assembly configured to drive the clamp arm between the open position and the closed position; and
(e) a clamp arm clocking assembly configured to drive rotation of the clamp arm about the axis relative to the ultrasonic blade between a first clocked position and a second clocked position, the clamp arm clocking assembly comprising:
(i) a rotating body configured to rotate relative to the ultrasonic blade about the axis, wherein the clamp arm is pivotally coupled to the rotating body, and
(ii) a drive assembly at least partially extending through the articulation section, wherein the drive assembly is configured to convert translational motion into rotational motion of the rotating body, wherein the drive assembly comprises a rack and a compound gear.
