Patent ID: 8613617

Claim:
An ultrasonic dental insert comprising: a first transducer for generating ultrasonic vibrations; a connecting body having a proximal end and a distal end having a tip attached thereto, the proximal end attached to the first transducer so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip attached to the distal end, wherein the connecting body comprises a material having magnetic permeability; a second transducer disposed substantially proximate to the connecting body for generating a voltage signal in response to movement of a portion of the connecting body according to the ultrasonic vibrations due to the magnetic permeability of the connecting body; at least one rare earth magnet in close proximity to the connecting body, wherein the at least one rare earth magnet is mounted in a stationary position such that the connecting body moves relative to the at least one rare earth magnet; and at least one light source substantially proximate to the tip, said at least one light source being connected to and receiving the voltage signal from the second transducer to generate light.
