Summary:An apparatus comprises a body assembly and a shaft extending distally therefrom. The shaft defines a longitudinal axis. The apparatus further comprises an acoustic waveguide and an articulation section coupled with the shaft. A portion of the articulation section encompasses a flexible portion of the waveguide. The articulation section further comprises first member and a second member that is longitudinally translatable relative to the first member. The apparatus further comprises an end effector including an ultrasonic blade in acoustic communication with the waveguide. A distal portion the ultrasonic blade is disposed in a first direction away from the longitudinal axis at a bend angle. The end effector also includes a clamp arm that is coupled with the first member and the second member, and an articulation drive assembly operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis in the first direction.
