ULTRASONIC DENTAL TOOL HAVING A LIGHT SOURCE

摘要

An ultrasonic dental insert having at least one light source. A first
transducer generates ultrasonic vibrations. A connecting body has a proximal
end and a distal end having a tip attached thereto. The proximal end is
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. A second transducer is 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. A
magnetic material including a source of a magnetic field is present in close
proximity to the insert. At least one light source substantially proximate to
the tip is connected to and receives the voltage signal from the second
transducer to generate light. The ultrasonic dental insert may be inserted
into a handpiece for providing electromagnetic energy to the first transducer
to generate the ultrasonic vibrations.
