Embodiment Construction

[0033] Examples see Figure 1-3 As shown, this disposable high-speed turbine dental drill handpiece with a light emitting device includes a head 1, a front handle 2, a rear handle 4 and a quick-fit joint 23, a drill 7 is installed on the head, and the front handle and The water passage 24 for cooling the drill and the air passage 27 for driving the drill are communicated with the machine head in the rear machine handle. The front machine handle 2 is connected with a triangular lamp holder 5 for installing a light emitting diode 6 near the machine head 1. The head of the light emitting diode 6 is exposed from the hole of the lamp holder and is opposite to the cutting part of the drill 7. Each electrode is connected to two LED leads 20 respectively.

[0034] see Figure 4 As shown, there are two electrode sockets at the end face of the rear handle, the electrode sockets are made of copper wire or copper sheet, and the end of the light-emitting diode lead has a plug connected w...

Abstract

The invention relates to a disposable high speed turbine dental drill handpiece with a light producing device which is characterized in that a place of a front operating handle close to a handpiece isconnected with a lamp socket for installing a light-emitting diode, the head of the light-emitting diode is exposed from a hole of the lamp socket and opposites to a cutting position of a dill point,two electrodes at the tail part of the light-emitting diode are respectively connected with two light-emitting diode lead wires; a rear operation handle is provided with a battery bin which is provided with a battery bin cover, a space containing a illuminating gas switch is arranged below the battery bin, the bottom of the space is communicated with an air passage of the illuminating gas switchin the rear operating handle, the air passage of the illuminating gas switch is parallel to the air passage of a driving drill point and the two air passages are both communicated with a gas pipelineat the tail part of the rear operating handle, a button battery is put in the battery bin, the positive pole of the button battery is communicated with a lead wire of the light-emitting diode, and thenegative pole of the button battery is connected with the other lead wire of the light-emitting diode by the illuminating gas switch. The dental drill handpiece is characterized by low cost, safe andconvenient use, and good illuminating effect, and is applicable to be arranged in various dental units.

Description

technical field [0001] The invention relates to a hand-held appliance for medical drilling and grinding teeth. Background technique [0002] The intraoral lighting device of the high-speed turbo dental drill mobile phone generally adopts the optical fiber light source transmission technology, that is, a lighting bulb or a light-emitting diode is installed at the tail of the mobile phone handle or in the quick-fit joint. The light is guided into the front of the handpiece through the optical fiber for the illumination of the oral cavity during treatment. [0003] This kind of device requires the treatment machine to provide power to ignite the small bulb, and a set of circuit transmission devices connected to the power supply, such as gold-plated double-ring contacts, six-hole connectors, etc. The power supply is generally obtained by converting an AC high-voltage power supply (such as 220V AC 50 Hz). Therefore, reliable safety facilities are required to ensure that users a...
