Abstract

The invention relates to a light comprehensive therapeutic instrument, which is a medical optical therapeutic instrument, wherein a halogen lamp (6) is used as a full spectrum light source, a reflector (7) converges light on the end surface of a conical light guide rod (4) and light irradiated on the incident end surface of the conical light guide rod (4) by a bulb (6) is effectively transmitted to the output end of the conical light guide rod (4) to form high-intensity light spots for irradiating focus parts and treating diseases, cancer tissues are selectively absorbed and killed by light, and the light comprehensive therapeutic instrument has special effects for treating early and middle stage superficial cancers and can be directly inserted into organs such as ears, noses, oral cavities, vaginas, anus and the like for light irradiation treatment.

Description

Light combination therapeutic equipment

Light combination therapeutic equipment is a kind of medical optical therapeutic equipments.With rayed body foci with visible light-near infrared light spectral property.The body heat effect can be treated disease; Cancerous tissue absorbs the light selectivity is killed, treatment early, mid-term shallow table cancer.

The near infrared-ray treating device for cancer in oral cavity of 85105520A number record of disclosed Chinese invention patent ublic specification of application CN on January 21st, 1987, it is made up of halogen tungsten lamp, tapered light pipe, hemisphere face reflector, water light filter.The light that halogen tungsten lamp sends becomes the hot spot of a circle to project the inlet of light guide through hemisphere face reflector reflect focalization, is penetrated by outlet after reflection for several times in light guide, is radiated at lesions position, the treatment cancer.The tapered light pipe disadvantage is a light through tube wall reflex time for several times, and most of luminous energy is absorbed by tube wall and changes heat energy into, and optical energy loss is bigger.Other positions of the overheated easy scalded patient of tube wall.And therapy apparatus technology, complex structure use inconvenient.

The object of the present invention is to provide a kind of high power density, optical energy loss few, the tapered rod point diameter is little, human body is not had the light combination therapeutic equipment device of scald.Promptly be suitable for outside treatment exposed department of dermatologry, the department of stomatology and the gynaecopathia, but pleasant, the nose of skewer, anus again, even subcutaneous tissue light exposure treatment focus.

The object of the present invention is achieved like this: a kind of light combination therapeutic equipment, include lamp house (8), in put and reflect bulb, it is characterized in that lamp house the place ahead is equipped with the optical transmitting set that taper lamp guide (4) constitutes, and is provided with recirculated cooling water in the lamp house.

Purpose of the present invention also can realize like this: a kind of light combination therapeutic equipment includes lamp house (8), interior dress halogen lamp (6), illuminator (7), it is characterized in that lamp house the place ahead is equipped with the optical transmitting set that taper lamp guide (4) constitutes, and is provided with recirculated cooling water in the lamp house.

Compared with the prior art light combination therapeutic equipment of the present invention has following advantage:

1, lamp guide has adopted taper lamp guide (4) in the optical transmitting set (comprising halogen lamp, reflective optical system, lamp guide three parts composition).Make by saturating near infrared quartzy optical glass.Characteristics are that the taper lamp guide has the power density amplification to the luminous energy that incides incident end face at exit end.Amplification is by incident end face diameter and outgoing end face diameter ratio n decision.Here any number between n=1～5.The optical focus place hot spot of irradiation treatment is little, and the optical power density height can reach 50 watts/cm²Can be light treatment, spectral characteristic is provided is the radiating intense light source of Visible-to-Near InfaRed.

The light combination therapeutic equipment projection lamp power of 2, employingscheme 1 is that 75W gets final product, and its reason is that bulb has high efficiency and directivity, and light is directly delivered to the input of taper lamp guide, and optical energy loss is minimum, the power density height.

3, the reflective optical system of scheme 2 adopts the illuminator of dark ellipsoid shape.The filament of halogen lamp (6) is installed in first focal position of ellipsoid, and taper lamp guide (4) incident end face is positioned at second focal position of ellipsoid.Reflecting mirror (7) is with Halogen light side direction, back to the incident end that converges to lamp guide greater than the angle light radiation of π space multistory.And only passing light through taper lamp guide direct projection and total reflection, light loss is very little, so the light combination therapeutic equipment efficiency of light energy utilization of the present invention is high.Even illuminator (7) can adopt spherical reflector.

4, because the taper lamp guide has the output of high power density luminous energy (can reach 50 watts/cm²More than), but out of focus is used the still large spot irradiation (more than the φ 40mm) of high power output, be fit to the large tracts of land lesions position is treated, be the handled easily person, at the lamp guide exit end toroidal locating ring (1) can be installed, accurate location can be provided, safe and reliable to patient's light exposure treatment, also can alleviate operator's labor intensity.

5, the narrow band pass filter (2) of different wave length can be installed in the lamp guide exit, select to treat optical band for the operator, and provide monochromater for medical research.

6, lamp guide outfan (comprising protective sleeve urceolus (3)) is the thinnest is φ 4(mm) diameter; organ skewers such as particularly suitable ear, nose, oral cavity, vagina, anus are gone into photoradiation treatment; lamp guide is compared with light pipe in addition; the tube wall heat absorption is few; optical energy loss is few; the people is not had scald, save the water-cooled facility, simplify the structure.

7, the luminous energy loss is little, the utilization rate height, but the Halogen light low voltage power supply uses, reduces mains transformer power, volume, weight, saves energy, reduction treatment cost.Instrument is easy to carry, is ideal optical therapeutic instrument.

Be described in detail technical solution of the present invention below in conjunction with accompanying drawing.

Fig. 1 is the sketch map of light combination therapeutic equipment.

As Fig. 1, light combination therapeutic equipment includes lamp house (8), and interior dress halogen lamp (6), illuminator (7) is characterized in that lamp house the place ahead is equipped with the optical transmitting set that taper lamp guide (4) constitutes, and is provided with recirculated cooling water in the lamp house.

Above-mentioned illuminator adopts the illuminator of dark ellipsoid or less than the spherical reflector of hemisphere.

Halogen lamp 6 andilluminator 7 can be replaced by projection lamp in the such scheme.

Taper lamp guide of the present invention is to handle through optical polish with quartzy optical glass manufacturing, both ends of the surface and side, and the both ends of the surface diameter is than being number between 1～5, and plane of incidence diameter is greater than the exit facet diameter, and outlet diameter is less than φ 10mm.But taper lamp guide port of export installation accessories toroidal locating ring (1) and optical filter (2).

The rearward end of taper lamp guide is provided with lampguide support ring 5
