Abstract
An improved ultrasonic surgical handpiece includes an angled connecting body between the transducer and operative tip, with the connecting body being bent at a location between the node and antinode at its respective ends and with a second nodal plane support in the transducer section. The vibrating assembly is impedance matched to the frequency of a handpiece employing a straight connecting body of subtantially equal length and dimension whereby straight and angulated handpieces may be interchangeably used in an ultrasonic surgical system employing a common drive and common operative tips. In a preferred embodiment, the ultrasonic transducer has a nodal plane midway between its ends and is supported at this nodal plane.
