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: 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.
