Silent handpiece with lights

Abstract

A noiseless handpiece providing indicator lights. The head portion of the handpiece has one or more internal silencers for baffling the noise that is a byproduct of the generation of the rotational force used to drive the drill component. The indicator lights communicate one or more operational states to the user and reflect the engagement of an electrically connected transducer.

(2) FIG. 2 is a perspective view of an exemplary embodiment of the present invention, illustrating the bend 11 in the handle 10; and

(3) FIG. 3 is a front elevation view of an exemplary embodiment of the present invention, with light colors indicated by hatching for clarity.

DETAILED DESCRIPTION OF THE INVENTION

(4) The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

(5) Broadly, an embodiment of the present invention provides a noiseless handpiece providing indicator lights. The head portion of the handpiece has one or more internal silencers for baffling the noise that is a byproduct of the generation of the rotational force used to drive the drill component. The indicator lights communicate one or more operational states to the user, reflecting the engagement of an electrically connected transducer.

(6) Referring now to FIGS. 1 through 3, the present invention may include a noiseless handpiece 100 having a handle 10 with a proximal end and a distal end. The proximal end is connected to a head portion 12 and the distal end connected to an electrical connector 26. The electrical connector 26 may include a wire or be a wireless device that can received electrical inputs.

(7) The handpiece (or dental drill) 100 has internal mechanical components which initiate a rotational force and provide power to the cutting instrument, the burr 16. Toque could range between 150 000 to 200,000 rpms. Along an opposed end of the burr 15, the head portion 12 may provide a release mechanism 14 for selectively remove and replace burrs 16. The head portion 12 has an internal silencer 18 that baffles the noise generated by said mechanical components.

(8) A transducer 28 may be electrically connected to the electrical connector 26. The transducer 28 may be a configured to be a variable resistor (e.g., rheostat) which is used to control current (through varying the resistance in a circuit embodied in the handpiece 100) without interruption. The transducer 28 may be a foot pedal for the convenience of a dental practitioner.

(9) Along the handle 12, a plurality of light emitters 22-26 may be provided. The figures show three: red (stop) 22, green (go) 24, and yellow (activated) 26, but it should be understood that there could be more or less light emitters. The plurality of light emitters 22-26 may be logically designed to light up as indicators when a user selectively engages the transducer 28, thereby communicating to the user that the handpiece 100 is operational, even though noiseless because of the silencer(s) 18. In certain embodiments, each light emitter is circumscribed by a tooth design that lights up with activation of the respective light emitter.

(10) A method of using the present invention may include the following. The handpiece 100 disclosed above may be provided. The dental practitioner would electrically power the handpiece 100 and transducer 28 and utilize the burr 16 noiselessly.

(11) Additionally, the present invention may be applied to other power drills, power cutters, or any power tool that is too loud for its work environment.

(12) It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
