Abstract
An ultrasonic transducer of the magnetostrictive type in which the stack of laminations is divided into sections and at least one fluid supply tube extends at least part way along the length of the stack in the space between the two sections. One of the tube supplies irrigation fluid to the interior of the handpiece from which it exits through a sleeve succeeding the transducer tip. An elastic membrane sleeve surrounds the transducer vibrating structure to prevent interaction between the fluid and the transducer and consequent loss of power. The end of the work tip is hollow and the material is drawn therein to be emulsified by the ultrasonic energy radiated from the internal wall of the hollow end.
