Benefits of technology

"The present invention is a lighted ultrasonic dental scaling handpiece that provides better visibility and comfort for dental technicians and patients. The handpiece features a scaling tip, a velocity transducer, an ultrasonic stack, and a light source. The light source is connected to the scaling tip through a translucent grip body, which is covered by an interchangeable grip sheath for easy gripping and color identification. The lighted grip system can also be designed with a molded body and a translucent insert for transmitting light to the grip and a lens for viewing images. The technical effects of the invention include improved visibility, comfort, and ease of use for dental technicians."

Problems solved by technology

Although various prior art devices disclosed mounting a light or light source in the handpiece, so far as known to applicant, no prior art provides a light path through the insert grip to guide remotely generated light to the tip of the scaler.

Embodiment Construction

[0036] The present invention relates to a dental scaling insert providing a translucent path from a light source to the end of the handpiece through a translucent grip covered by an ergonomically designed resilient sheath. In a preferred embodiment shown in FIG. 1, insert system I is comprised of a magnetostrictive stack 14 typically formed of nickel or nickel alloy plates in a manner well known to those skilled in this art, which are soldered together and which respond to electrical energy supplied by coil 19 encircling stack 14 in the handpiece H. Stack 14 is connected to a velocity transducer 16 which is connected to a scaling tip 18 and which is covered with grip 10. Grip 10 is formed from two segments or pieces of high grade plastic, for example, such as a polycarbonate, that provide a profile on their interior surface to retain the velocity transducer 16. In this embodiment, one or more teeth 13 are provided on the exterior lateral surfaces of the velocity transducer 16 to pre...

Abstract

The present invention relates to a dental scaling translucent insert which provides a coaxially aligned light adjacent the distal end of such insert for illuminating the tip of the dental scaler which light may be provided by light emitting from a fiber optic light guide from a light source located remotely from the tip. The light provided can also be used to view through a camera lens system located in translucent insert to provide a clear unobstructed view of the work at the tip of the scaler on a remote screen or for recording.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. Ser. No. 10 / 249,165 filed Mar. 19, 2003, now U.S. Pat. No. 7,150,629.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a medical or dental handpiece; specifically to an ultrasonic handpiece providing a independently controlled light source connected through an interchangeable and easily identifiable grip on an ultrasonic insert adjacent the end of the handpiece for illuminating the surface to be engaged by the tip of the handpiece and which may additionally provide a camera lens for viewing the work area without interference with the work performed. [0004] 2. Description of the Related Art [0005] The present invention relates to an ultrasonic tool, which can be a dental scaler, or—alternatively—a scalpel, additionally providing a light directed from the handpiece of the tool toward the work surface on which the tip or blade is engaged. For ease...
