Abstract
A medical instrument includes a handpiece, an electromechanical transducer disposed in the handpiece, and an electrical circuit disposed at least partially in the handpiece for supplying alternating electrical current of a predetermined frequency to the transducer. A probe is operatively connected to the transducer for transmitting vibrations generated by the transducer to an operative site in a patient. A switching device is mounted to the handpiece and is operatively connected to the circuit and the transducer for enabling the supply of power to the transducer during a motion of the probe in a preselected direction relative to the handpiece and for disabling the supply of power to the transducer upon a termination of motion of the probe in the preselected direction.
