Abstract
The present invention relates to a light treating machine for cancers in mouth cavity, etc., which belongs to a physiotherapy instrument. The present invention adopts visible near infrared light with 1 to 2 watt / centimeters + 2 power intensity to irradiate cancer tissues, so that the cancer tissues can be selectively killed and the damages of normal tissues are small; the machine has high specificity ratio for treating oral cancer, skin cancer, uterine cancer, etc. The machine uses a tungsten halogen lamp [6] as a light source, and the light is converged to the inlet of a conoid light pipe [2] through a hemispherical reflector [4], so that the outlet obtains a bundle of strong light which can reach 30 watt more or less, and the light beam is used for irradiating the cancer tissues. The machine can also use a water light filter [8] so as to improve the action of selectivity.
Description
The invention belongs to physical therapy appliance.
The method for the treatment of cancer has the methods such as operation, chemotherapy, radiotherapy, laser therapy at present.Laser therapy has two kinds of methods (Ga To Kagaku Ryoho(JAPAN) Jun 1983 10(6) p1387-94).A kind of is with light laser (40～80 watts) cancerous tissue to be vaporized, and is called for short gasification.Another kind is hemoporphyrin laser method (Cancer Research Vol 38 2628-2635 Angs 1978).Gasification vaporize simultaneously cancer and normal structure, the non-selectivity effect, the normal tissue damage is bigger, and is general only as alleviation means (The American Journal of Surgery Vol 143 March 1982 p281).The selective effect of hemoporphyrin laser method can remove more up hill and dale cancerous tissue, but the patient needed lucifuge one month, comparatively trouble.The hemoporphyrin laser therapy for cancer can be treated early stage visceral cancer, but visceral cancer is indiscoverable in early days; The in addition complexity of laser instrument, laser therapy for cancer still is difficult at large propagation and employment at present.
For the problem that above-mentioned treatment cancer method exists, the present invention has made a kind of can generally promoting the use of, and cost is low, and volume is little, and is portable, the higher near infrared-ray treating device for the treatment of cancer in oral cavity specially good effect rate.This machine is made up of optical transmitting set and power pack.Characteristics of the present invention are that to have power big, and facula area is big, to the selective lethal effect of cancerous tissue, can more thoroughly remove thus the optical transmitting set of cancer in oral cavity focus.
Fig. 1 is the sketch map of optical transmitting set part of the present invention.It is by halogen tungsten lamp (6), tapered light pipe (2), and hemisphere face reflector (4), water Shanghai light device (8) forms.
The key technology requirement that the present invention can treat cancer is: (30 watts/centimetre of bigger optical output power density
2), bigger facula area (10 millimeters of＞φ), wavelength is in visible near infrared range (about 1.04 microns) one by one.Power demand density is about 1-2 watt/centimetre during actual therapeutic
2; But this machine once irradiating area is 15-30 centimetre like this
2The carninomatosis kitchen range.Reach These parameters, just must adopt this emitter.Be light source with 300-600 watt of halogen tungsten lamp (6), optical path hemisphere face reflector (4) reflect focalization that sends becomes a garden shape hot spot.Hemisphere face reflector surface aluminizer, it all has higher reflection coefficient to visible light-near infrared light.The dot projection that reflect focalization forms is to the entrance of light guide (2).In light guide, after for several times reflection, penetrated by outlet.The effect one of tapered light pipe is for light conducting, the 2nd, and for being converged, hot spot attenuates.The light guide inlet diameter is greater than outlet diameter, and inlet diameter is slightly less than again spheric reflector and converges the spot diameter that forms.Like this, during the change of light path part position, the output of machine can not reduce, and this has just ensured the stability of output.
Tapered light pipe of the present invention is formed by attaching-mica sheet in the metal tube, and mica sheet plating metal on surface film (silver or aluminum) forms the bright specular layer of aurora.For making it firm, need carry out oxidation.For avoiding mica sheet to break, also need spray one deck plasticising film.Mica sheet is cut into needed shape, is rolled into tube, fill in the good cone-shaped metal pipe of prior car.Because mica sheet is very thin, and has certain elasticity, fill in behind the metal tube just automatic laminating forms the tapered light pipe that inwall is specular light on the inwall of metal tube.
Water Shanghai light device among the present invention is that absorbent far infrared is anhydrated partly in Shanghai, because the content of water is very high in the human body.Employing water Shanghai light device can increase the selectively acting to cancerous tissue.But light intensity descends to some extent, sometimes in order to increase light intensity, and does not make water Shanghai light device (8), but at this moment will lose some selectively actings.
The both ends of the surface of water Shanghai light device (8) should adopt two optical plate glass, and its thickness is 1 millimeter, and it is high that transparency is wanted.The sealing of employing elastic tape.Shanghai light device water layer thickness is advisable with the 1-2 millimeter, and water layer should be able to flow, so that heat radiation.Flow inlet is lower, and outlet is upper, and discharge is 0.2 liter/min.Whole Shanghai light device should be able to be dismantled, so that routine cleaning.
This machine adopts cooling jacket to dispel the heat, and discharge should be not less than 0.5 liter/min.The technical specification of this machine is as follows:
Output light-wave wave-length coverage: visible light-near infrared light
Output optical power: 0-30 watt continuous adjustable
10 millimeters of spot diameter:＞φ
Output optical power stability: after complete machine is moved, install, without adjusting, power does not descend again.
Power supply: 220 volts, 50-60HZ, maximum consumption is no more than 600 watts.
Water cooling: tap water cooling, 0.5 liter/min of streamflow.
This machine can be treated the cancers such as oral cavity, skin, cervix uteri.Wherein with treatment oral cancer meaning maximum.Oral cancer can be found at early metaphase, uses surgical operation therapy, and the patient can cause facial deformity, and the relapse rate height; Use radiotherapy, the chemotherapy meeting brings serious side effect to the patient.And this machine treatment early, mid-term oral cancer, specially good effect rate height, effect is better than laser, and simpler.In addition, it is low that this machine also has relapse rate, do not destroy face, without any side effects, simple without lucifuge, patient's advantage such as need not be in hospital.This machine treatment cancer in oral cavity is used Other Instruments at present, and method is all superior.
Account for 9.97%(Shanghai second medical college statistics of whole cancers at China's oral cancer), the People's Hospital, 1.45-5.6%(Tianjin statistics).Add skin, cervical cancer is interior, about three kinds of about 100,000 people of cancer year number of the infected.
Abroad, the sickness rate of India's oral cancer accounts for 50% of whole cancers, Southeast Asia one band, and the sickness rate of oral cancer accounts for 40% of whole cancers.In European and American countries, the sickness rate of oral cancer is generally than China's height, and the sickness rate of skin carcinoma accounts for the 30-50% of whole cancers.This machine to the morning in the above-mentioned cancer, mid-term the patient basically can both reach the therapeutic effect of specially good effect.(specially good effect: cancerous tissue can all come off, the cancerous cell of noresidue.）
