ABSTRACT:
An ultrasonic tissue dissection system providing combined longitudinal and torsional motion of tips, together with irrigation and aspiration, for improved cutting of resistant biological tissue. The system permits the use of common and inexpensive electro-mechanical transducers for the production of such motion through the use of longitudinal-torsional resonators.
