Abstract: An ultrasonic surgical instrument includes a housing, a waveguide extending distally from the housing, an end effector coupled to the distal end of the waveguide, an ultrasonic transducer retained within the housing, and a controller. The ultrasonic transducer is coupled to the proximal end of the waveguide and configured to produce mechanical motion for transmission along the waveguide to the end effector. The controller is configured to control an amplitude of the mechanical motion of the ultrasonic transducer in accordance with at least one amplitude value. The at least one amplitude value is adjusted according to an age of the ultrasonic transducer to compensate for aging of the ultrasonic transducer. Methods for controlling the amplitude of the mechanical motion of an ultrasonic transducer to compensate for aging of the ultrasonic transducer are also provided.

Abstract: A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the insulative surface. A second jaw member of the end effector assembly includes an ultrasonic blade body positioned to oppose the insulative surface of the first jaw member, and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the ultrasonic blade body and positioned to oppose the first and second electrically-conductive surfaces, respectively, of the first jaw member. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The first and second electrically-conductive surfaces of the second jaw member are movable, independent of the first jaw member, relative to the first jaw member and the ultrasonic blade body between a retracted position and an extended position.
