Abstract

A medical instrument includes a handpiece (12), an electromechanical transducer (14) disposed in the handpiece (12) and an electrical circuit (100) disposed at least partially in the handpiece for supplying alternating electrical current of a predetermined frequency to the transducer (14). 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 (98) is mounted to the handpiece and is operatively connected to the circuit (100) and the transducer (14) for enabling the supply of power to the transducer (14) during a motion of the probe in a preselected direction relative to the handpiece (12) and for disabling the supply of power to the transducer (14) upon a termination of motion of the probe in the preselected direction.

Claims (25)

1. A medical instrument comprising:
a handpiece;
an electromechanical transducer disposed in said handpiece;
