Abstract: Systems and methods are disclosed comprising an ultrasonic handpiece having a housing, a working tip extending from the distal end of the housing, and a crystal and horn assembly positioned within the housing. The proximal end of the ultrasonic horn is free to move relative to the housing. In embodiments, the ultrasonic horn is resiliently suspended within the housing, with no rigid fixation points. The ultrasonic horn may be resiliently suspended by one or more resilient rings at the proximal end of the ultrasonic horn and by one or more resilient rings at the single nodal region of the ultrasonic horn. The ultrasonic handpiece may include a pumping module located at the proximal end of the handpiece.
