    Abstract: An ultrasonic surgical instrument comprises a handpiece and an ultrasonically actuated blade distal to the handpiece. The instrument includes an activation member that is operable to selectively activate the blade and a controller that is operable to select the energy level at which the blade will be activated. The activation member may comprise capacitive switches; resistive sensors; resonant cavity switching technology; infrared sensing technology; technology that uses a resonant, standing wave on a surface that is perturbed by the presence of a finger; and/or any other suitable type of technology. The controller may comprise the same. The controller may permit selection from three or more available ultrasonic energy levels. The activation member and/or controller may be manipulated from various longitudinal positions on the handpiece and/or various rotational positions about the handpiece, such that the handpiece may be gripped in a variety of ways.

    Abstract: An apparatus for operating on tissue includes a body, a shaft, an ultrasonic blade, and an acoustic assembly. The shaft extends distally from the body. The blade is disposed at the distal end of the shaft. The acoustic assembly comprises an acoustic waveguide coupled with the blade, a piezoelectric transducer element, a fastener, and a coupling member. The transducer element defines an inner diameter surface and an outer diameter surface. The fastener is configured to secure the transducer element relative to the waveguide. The coupling member is configured to provide electrical continuity between the fastener and the inner diameter surface of the transducer element. The outer diameter surface of the transducer element includes an annular recess. Another coupling member is configured to provide electrical continuity between the annular recess of the piezoelectric transducer element and a power source while permitting the piezoelectric transducer element to rotate relative to the body.
