Embodiment Construction

[0029] In an exemplary embodiment of the present invention, the ultrasonic dental insert has at least one integrated light source, such as a light emitting diode (LED), which enables the dental practitioner to project light on the working field of view while acting on the teeth . The light source is excited by the already available ultrasonic vibration energy, so no additional energy source is needed. As an example, a transducer such as and / or including an illuminating energy coil is provided and assembled on the light source, so the light source can be excited with the vibration energy converted by the transducer. For example, when the connector of the dental insert moves quickly, an alternating current (ac) voltage is generated in the lighting energy coil, and the alternating voltage is connected in series with a light source (such as a light emitting diode (LED)) to provide energy for light emission. In other embodiments, any other suitable transducer can be used to convert vib...

Abstract

The present invention provides an ultrasonic dental insert having at least one light source (101). A first transducer (108) generates ultrasonic vibrations. A connecting body (103) has a proximal end and a distal end having a tip (102) attached thereto. The proximal end is attached to the first transducer (108) so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip (102) attached to the distal end. A second transducer (99) is disposed substantially proximate to the connecting body (103) for generating a voltage signal in response to movement of a portion of the connecting body (103) according to the ultrasonic vibrations. At least one light source (101) substantially proximate to the tip (102) is connected to and receives the voltage signal from the second transducer (99) to generate light. The ultrasonic dental insert may be inserted into a handpiece for providing electromagnetic energy to the first transducer (108) to generate the ultrasonic vibrations.

Description

Technical field [0001] The invention relates to an ultrasonic dental instrument, more specifically, to an ultrasonic dental instrument with a light source. Background technique [0002] Dental practitioners use ultrasonic dental instruments (tools) to perform dental therapies and operations, such as curettage, periodontal therapy, and root canal therapy. Ultrasonic dental instruments usually include a handle with one end (that is, the proximal end) coupled to a power source and a liquid source through a cable. The cable includes a hose for supplying liquid (such as water) and a wire for supplying electrical energy. [0003] The other end (that is, the distal end) of the handle has an opening for receiving a replaceable insert, and a transducer (such as a magnetostrictive transducer) is installed on the insert. The transducer extends from the proximal end of the insert into the hollow interior of the handle. The working tip for ultrasonic vibration protrudes from the distal end of...
