Publication number: 20240090915Abstract: Some implementations provide a high-powered compact ultrasonic transducer having an integral piezoelectric ceramic force sensing element utilized to enable enhanced tissue selectivity with a piezoelectric based transducer. Some implementations additionally or alternatively relate to methods and apparatus for driving ultrasonic surgical devices, such as methods and apparatus that modulate an amplitude of a drive signal, provided to an ultrasonic surgical device, in accordance with a selected tissue selectivity level. For example, the amplitude of the drive signal for a given tissue selectivity level can be varied with time in accordance with amplitude modification parameters that are particularized to the given tissue selectivity level. Some of those implementations additionally implement a corresponding duty cycle, for the drive signal, that corresponds to the selected tissue selectivity level.Type: ApplicationFiled: July 17, 2023Publication date: March 21, 2024Inventors: Daniel J. Cotter, Prakash Manandhar, Nicholas Allen, Saurav V. Gupta
