Abstract: An ultrasonic resonant vibrator comprising an ultrasonic vibration magnetostrictive transducer (1) and a resonant member (2,3) having a proximal end and a distal end for transmitting ultrasonic vibrations to an operating member (3) which is part of the resonant structure. The vibrator comprises an integral substantially rigid column having a central axis with fins extending radially relative to said axis and having a longitudinal hole defining a tunnel (8) centered along the central axis, wherein at least part of the resonant member is located within the tunnel; and a surgical handpiece incorporating such a vibrator.

Abstract: An apparatus having a vibratable tip (22) for ultrasonically disintegrating tissue in a surgical procedure and for aspirating the disintegrated tissue and fluid away from the surgical site (12) through an opening (24) in the tip. A connection (42) to the electrosurgical unit provides for delivery of RF cutting current, RF coagulating current or a blend thereof to the tip so that electrosurgical procedures can be conducted separately or simultaneously with ultrasonic aspiration through the tip. It thus is now possible, for example, to electrocauterize simultaneously with ultrasonic fragmentation with a single handheld surgical device. The simultaneous delivery of ultrasonic vibrations and RF current to the tip also has been found to increase the tissue fragementation rate.

Abstract: A method and apparatus for periodically interrupting ultrasonic power applied to a ultrasonically vibrating tip to control its amplitude between high and low or zero amplitudes with a selectible duty cycle and repetition rate provides enhanced fragmentation and improves surgical control. The duty cycle may also vary as a function of a remotely sensed parameter such as tissue temperature.
