Claim 14:
15. An ultrasonic surgical instrument, comprising:
(a) a shaft assembly, comprising
(i) a proximal shaft portion extending along a first longitudinal axis,
(ii) an articulation assembly, and
(iii) an ultrasonic waveguide comprising a flexible portion housed within a section of the articulation assembly;

(b) an end effector extending distally from the articulation assembly, wherein the articulation assembly is configured to deflect the end effector toward and away from the first longitudinal axis between a straight configuration and an articulated configuration, wherein the end effector comprises:
(i) an ultrasonic blade extending from the ultrasonic waveguide, wherein the ultrasonic blade defines a second longitudinal axis, and
(ii) a clamp arm configured to actuate relative to the ultrasonic blade between an open configuration and a closed configuration in order to grasp tissue; and

(c) a clamp arm driver comprising a flexible section interposed between the section of the articulation assembly and the flexible portion of the ultrasonic waveguide, wherein the clamp arm driver is configured to actuate the clamp arm between the open and closed configurations and rotate the clamp arm relative to the ultrasonic blade about the second longitudinal axis while the end effector is in the articulated configuration,
wherein the flexible section is configured to be translated to thereby transfer translation therethrough, and
wherein the flexible section is further configured to be rotated to thereby transfer rotation therethrough.
