Description

Optical solidifying machine for dentist

This utility model relates to optics, fiberoptic technical field.Be again a kind of light, mechanical, electrical complex art simultaneously, be applied to aspects such as the dental filling of medical circle dentistry, modern dental aesthetics.

At present, the material that is widely used in dentistry dental filling and beauty treatment both at home and abroad mainly is the visible-light curing composite resin, this material is can be not solidified without the rayed of specific wavelength, like this, the doctor just has adequate time that cacodontia is carried out meticulous filling, arbitrarily moulding, and then with rayed it, make it to solidify.Provide the dental curing light machine of this illumination that the product of many kinds is all arranged both at home and abroad, optical fibre light guide is all used in the working end of these photo solidification machines, light is passed in the oral cavity, and can both the visible-light curing composite resin be solidified reliably.But these machines have with light supply apparatus on handgrip part, heavy un-skill, heat dispersion is poor, can not use continuously, and the sight line when influencing the doctor and operating, and the light wavelength scope of conduction is too wide, is not monochromatic light, the light of useless wave band is dazzling when making working doctor, causes eyes undue tired (as the pistol type photo solidification machine and the domestic similar imitation products of West Germany Gu Sha company, Bayer AG's production); Though the machine that has can overcome above-mentioned deficiency, light source switch is installed on the loom, not at handgrip part, and inconvenience when causing using (as Australian product and domestic similar counterfeit products); Alarm device during photograph end that these above-mentioned machines are all unglazed.

Task of the present utility model is to provide a kind of use flexibly light and handy for being extensive use of the light-cured composite material exactly, require to have periodic time indication for different light application times, and continuously adjustable not dazzling, can make the rapid solidified monochromatic photo solidification machine of material again.

Task of the present utility model solves by following proposal.(1) makes a special effective combination monochromatic filter, leach the monochromatic light of a specific wavelength; (2) make a special halogen tungsten nail; (3) make that a softness is light and handy, the optical fibre light guide of high permeability, and contain a very thin cable in the optical fiber, the light source trigger switch can be installed on the manual working end of light beam; (4) realize regularly electrical switch and audible alarm with electronic units such as medium scale integration (MSI)s.

Details of the present utility model, advantage and feature illustrate with the following example and accompanying drawing, but should only not be interpreted as the embodiment that this is limited to the claimed scope of this utility model.

Fig. 1, photo solidification machine functional-block diagram.

Fig. 2, electrical switch and music alarm block diagram.

What Fig. 1 represented is theory diagram of the present utility model, on scheming, can be clear that, at first regulate timing governor (1), timing Displaying Meter (2) promptly shows the second number of required illumination, manual working end (3) is aimed at the cacodontia mend, click the trigger switch (4) on the working end, this moment electrical switch (5) energized (6), cold emission halogen tungsten lamp (7) sends visible panchromatic light, monochromatic light (9) through combination monochromatic filter (8) output one specific wavelength, be transmitted on the composite resin of dental filling place by soft optical fibre light guide (10) working end, when finishing preceding 3 seconds at selected timing, alarm sound (11) sends melodious music, and indication doctor illumination closes to an end, subsequently lamp is closed, composite resin material solidifies.The one action process finishes, and until clicking trigger switch (4) once more, repeats said process.

Combination monochromatic filter (8) among Fig. 1 is characterised in that its prescription is as follows: SiO through specific prescription ₂+ B ₂O ₃54-65Wt%; Na ₂O+K ₂O 17-23Wt% Z _nO+PbO 15-25Wt% Fe ₂O ₃O-6Wt% CuO 0-3Wt% C _oO 0.2-1Wt%, according to this prescription and each component content thereof, melt out the extraordinary filter glass of two kinds of particular range of wavelengths, be processed into required yardstick and thickness then, be polished to eyeglass and form the filter set that can leach specific wavelength, and add the method for a slice vacuum coating optical filter, plate infrared reflection film, make the exhausted major part of hot line of the infrared band (800nm-2000nm) in the light wave reflect away, and the light wave that can see through is the monochromatic light belt that respectively has 20nm wide about the center with 470nm as far as possible, causes the monochromatic cold light of an only specific wavelength of light source output.

Another feature among Fig. 1 is that the performance of cold emission halogen tungsten lamp (7) is a self-focusing type, and only reflect the light of 450-490nm wavelength, the light transmission of all the other wave bands, therefore as long as on former Design of Luminaires, revise, promptly plate two film systems less, just can reach above-mentioned requirements, adding specific optical filter formation emergent light is single wavelength.

Another key character among Fig. 1 is that described optical fibre light guide (10) is to pull out fibre single thread (diameter is about 30um) with rod-in-tube technique; coiled bundle on spiral filament forming machine (light guide bundles diameter 6mm); simultaneously with a conductive cable (diameter is about 0.5mm) (the silicone rubber tube inwall has a spiral helicine steel band) in light guide bundles is inserted in the silicone rubber protecting tube; the two ends impregnation of light guide bundles; load onto the lip pencil working end; oven dry and grinding and polishing; simultaneously cable is connected on the trigger switch (4) (trigger switch voltage is lower than 10 volts, and handheld terminal is perfectly safe) and contact-connection assembly for electric of lip pencil working end.Form a softish optical fibre light guide that contains conductive cable and lip pencil working end and have trigger switch.

Shown in Figure 2 is, when clicking trigger switch K(1), single

Integrated package A(2) output one width is the positive pulse of setting up time in timing governor (3) setting up time, makes bidirectional triode thyristor (4) admittance, and halogen tungsten lamp (5) is lighted and sent light wave, and is when setting up time finishes, single Integrated package B(6) be triggered, output time is the positive pulse in 3 seconds, makes (4) continue 3 seconds of admittance, music-integrating block (7) sound equipment alarm in 3 seconds simultaneously, 3 second back light and sound equipment cease simultaneously and go out.

Be not difficult to find out in the technical characterictic from above; advantage of the present utility model and good effect are to contain in the optical fiber cable; work is partly light and handy and the light source trigger switch is housed; structure is light and handy; convenient during use, illumination is not dazzling to be conducive to the effect that the protection eyes were observed and played to working doctor, and timing is continuously adjustable and the instrument indication arranged; when light application time finished soon, melodious music notice working doctor closed to an end.
