Is especially suitable for treating dentin hypersensitiveness, acute gingivitis, pericoronitis, ulcer, hemangioma, leukoplakia, milky tumor, wart, etc. The method is characterized in that the method adopts Nd: YAP laser, and single optical fiber coupling, laser power measurement and digital power display which adopt He-Ne laser as aiming indication and have planar input and output ends. The output laser power is 0.3-3.5W, the pulse repetition frequency is 1-30 times/second, and the preselection is carried out by seven grades. The proper power is selected to carry out the irradiation treatment according to the disease condition.
Description
The present invention is the pulse laser therapy apparatus to the multiple disease treatment of the department of stomatology.
Usually the treatment of oral disease brings many miseries and uneasiness to patient.After laser comes out, post with hope and carried out many trials.The therapy equipment of a kind of caries prevention in a kind of Ya Ti Ya Marrow, periodontal, mucosa device for laser therapy and Jp78150402 (781204) document in the CN2042361U document, what the two all adopted is the random polarisation Nd:YAG laser instrument of output.Though having overcome the latter, the former adopts a long-focus lens, the shortcoming of inconvenient operation.But the former arranges unreasonable at the optical element of Laser Devices part.Not having laser power to show, is inconvenient in treatment obviously.
The objective of the invention is to design a kind of Nd:YAP laser instrument that adopts output polarization light, indicate as aiming with He-Ne laser, the input/output terminal of optical fiber is a planar simple optical fiber coupling pulse recurrence frequency and laser output power is all adjustable and shown by numeral, the multi-functional Nd:YAP laser dental unit that can both treat the multiple disease of the department of stomatology.
The present invention is by Nd:YAP laser system (4,5,6,7,8,9), circulating cooling system (22), laser power measurement system (10,11), fiber coupling system (12,13,14,15), panel control system (17,18,19), He-Ne laser aiming indication mechanism (1,2,3), treatment handle (16) and foot switch (23) are formed.Its complete machine divides upper, middle and lower-ranking, and light path system is placed on the upper strata, and Laser Power Devices are placed in the middle level, and circulating cooling system is placed by lower floor.
Technical scheme accompanying drawings of the present invention is as follows:
Accompanying drawing one is multi-functional Nd:YAP laser dental unit light channel structure figure.
Accompanying drawing two is multi-functional Nd:YAP laser dental unit profile sketch map.
The present invention adopts the xenon flash lamp (7) of filtering ultraviolet as pumping source, xenon lamp The absorption spectrum of emission spectrum and Nd:YAP laser crystal has preferably Spectral matching. Laser System is Nd:YAP laser bar (6), xenon flash lamp (7), laser pump cavity (5), total reflection film Sheet (4), half reflection diaphragm (9), Laser Power Devices (8) form. Laser bar (6) and xenon lamp (7) Carry out circulating cooling by circulating cooling system (22). He-Ne laser (1) and 45 ° of reflectance coatings Sheet (2,3) forms the aiming indication mechanism, adjusts 45 ° of reflection diaphragms (2,3) central axis of He-Ne laser beam central axis and Nd:YAP laser beam is parallel to each other. By Nd:YAP The laser of laser instrument output is told sub-fraction light ingoing power detector through beam splitter (10) (11) carry out power detection, the major part of all the other laser enters coupled system poly-of optical fiber Focus lens (12) focuses on by five dimension adjustment racks (14) fixing and adjustment through unthreaded hole (13) The optic fibre input end face, then the simple optical fiber (15) by the plane is transferred to treatment handle (16) Carry out irradiation treatment. The optical fiber both ends of the surface are formed by the cutting of optical fiber cutter, and all optical elements all Be separately fixed on two parallel keys on the base plate. Nd:YAP laser bar (6) and xenon lamp (7) Arranged parallel is in laser pump cavity (5), and laser pump cavity adopts chamber, single ellipse garden, ellipse garden rate e=0.4, 2a=40mm2b=36.6mm cooling system (22) adopts deionized water circulating cooling, stream Amount is controlled at 10-12 liter/min. Nd:YAP laser bar (6) is Φ 6 * 76mm, xenon lamp (7) Φ 6 * 70mm, laser output power are 0.3-3.5W, pulse recurrence frequency be 1 time/second～30 times/second, condenser lens (12), light hole is through being 10mm, focal length is 15mm. Quartzy Optical fiber (15) core diameter is 0.35-0.6mm, and length is 2m, allows bending radius greater than 60mm Simple optical fiber, the input and output end face of optical fiber is all the plane, and treatment handle (16) is used alloy Aluminium is made. Laser Power Devices (8) adopt switch change-over type power supply, earlier 50Hz are exchanged directly Be rectified into direct current, through switch transformed circuit, this direct current become midfrequent AC, in using again The frequency power transformer conversion, the voltage of intermediate frequency after the transformation obtains required Voltage-output through rectification.
The present invention is provided with three control systems on the plate in the above, comprises the power numeral Show (17) that membrane switch (18) is touched in power control, membrane switch is touched in pulse recurrence frequency control (19). The pulse recurrence frequency of sending as the xenon flash lamp (7) of pumping source is by face The pulse recurrence frequency control of panel control system is touched membrane switch (19) and is divided seven grades of preliminary elections, laser Power supply (8) touches membrane switch (18) by power control and divides ten grades of preliminary elections, power detector (11) The watt level that detects shows that by the power numeral (17) provide. By the fixing biography of adjustment rack Lose fibre (15), drawn by front panel top, Optical Fiber Transmission is to treatment handle (16), and is front The key switch (20) of power supply (8) and the high-voltage switch gear (21) of xenon lamp (7) are drawn in the panel bottom, Rear board is equipped with power line and floor push (23). Complete machine inside shown in figure two, on the branch, In, lower three layers, the upper strata is placed with the complete machine light path system; Laser Power Devices (8) are placed in the middle level, Lower floor's effect is put circulating cooling system (22).
The present invention is because employing Nd:YAP is laser instrument, and it can output polarization light. Fiber-optic output does not need long-focus lens, does not need to burn for spherical at fiber-optic output yet End face, both ends of the surface are all the simple optical fiber coupling on plane. Therefore, easy to operate, arteries and veins It is all adjustable to rush repetition rate and laser output power, and is shown by numeral, undoubtedly to dentistry The diagnoses and treatment of disease is more accurate, quick.
