Abstract
The invention discloses equipment for treating vitligo by utilizing turnable lattice dual wavelength laser. A superpulse CO2 laser device and an ultraviolet laser device are integrated in the equipment. Under the control of a control system, the superpulse CO2 laser and the ultraviolet laser can be outputted according to pulse width, peak value power and pulse power, which are required by therapy, are respectively outputted through a beam switcher according to requirements, and are outputted to a two-dimensional optical scanning polariscope system through a coupler and a guiding arm. Then, the laser beams are outputted by the optical scanning system in a lattice distribution form, and are irradiated on focuses of skin surfaces of patients after being focused by a focusing mirror, thus, the equipment for treating vitligo by utilizing turnable lattice dual wavelength laser is manufactured. The device is mainly used for treating vitligo, particularly is suitable for treating acral vitligo, and is also suitable for treating neurodermatitis (hypertrophic type), chronic eczema, psoriasis, trichophytia, alopecia areata, scleriasis, lymphoma cutis and the like.
Description
Technical field
The invention relates to dermopathic equipment such as laser therapy vitiligo, it is specially adapted to treat acra type vitiligo, possess the output of Ultra-Violet Laser and iraser simultaneously, also be applicable to lichen chronicus simplex (treatment of conditions such as hypertrophic), Yin Xiao disease, chronic eczema, alopecia areata, scleroderma, lymphoma cutis.
Background technology
Vitiligo (Vitililgo) is a kind of common depigmentation dermatoses, sickness rate is 0.5%～2%, present national number of the infected is about 2,000 ten thousand, its cause of disease and pathogeny do not have final conclusion so far as yet, be a worldwide treatment difficult problem, wherein be distributed in hands, foot, refer to, the acra type treatment at position such as toe difficulty the most, the leukodermic medicine of treatment does not all reach curative effect preferably on the domestic market at present.
In recent years Ultra-Violet Laser has been obtained better curative effect in treatment topical type vitiligo, its major advantage is wider for few, the high-energy of treatment number of times, the scope of application, little because of its facula area again, so it is little to normal skin influence on every side, be particularly useful for treating the limitation skin lesion, but to acra type therapy of vitiligo weak effect.Acra type patients with vitiligo is 0 (50% pigment production rate) through the curative effect of 10-20 treatment of Ultra-Violet Laser, the external at present patients with vitiligo to Ultra-Violet Laser therapeutic effect difference adopts external Ta Kemosi and Ultra-Violet Laser therapeutic alliance, the skin lesion of therapeutic alliance has 50% to reach at least 75% improvement, but acra type patients with vitiligo curative effect is not had improvement, and its cure rate is 0.Its reason is because the epidermal thickness at facial eyelid place is 50 μ m, and the epiderm skin thickness at brothers back is 1000 μ-2000 μ m, the penetration depth of Ultra-Violet Laser skin is about 50 μ m, therefore it is limited that Ultra-Violet Laser penetrates a degree of depth of end epidermis, can not reach the lymphocyte and the hair follicle deep tissue of tegumentary chromatophore and corium, not reach the expection therapeutic effect.
To sum up state, Ultra-Violet Laser treatment vitiligo has become the most effective Therapeutic Method in the world medicine scope, development along with laser technology, adopt Ultra-Violet Laser treatment vitiligo to be adopted by the competent hospital in various countries, but the therapeutic effect at positions such as adversary, foot, back is very poor, and the therapy of vitiligo at these positions has been difficult and complicated illness.
Summary of the invention
Poor in order to solve the Ultra-Violet Laser penetration power, only can be penetrated into about 50 μ m at skin surface, do not reach the required irradiation degree of depth of treatment, therefore when having the vitiligo pathological changes of fold place, treatment acra type leukoderma and skin then do not reach this problem of therapeutic effect, we have adopted super pulse CO 2 laser to treat light source as another, because the laser beam that super pulse CO 2 laser produces is tunable pulsewidth, the iraser light beam of 10.6 micron wave lengths of peak power and pulse frequency, therefore not only being particularly suitable for skin histology absorbs, and when acting on skin surface, can form the micropore of depth controlled, like this at treatment acra type leukoderma and skin, when being arranged, the vitiligo pathological changes of fold place just can reduce the thickness of skin, make Ultra-Violet Laser can act on the lymphocyte and the hair follicle deep tissue of tegumentary chromatophore and corium, reach the effect of treatment.
The technical scheme that the present invention takes is to have adopted super pulse CO 2 laser and two laser instrument of Ultra-Violet Laser (super pulse CO 2 laser light beam wavelength is 10.6 microns as the treatment light source, average output power is 0～80 watt, the Ultra-Violet Laser light beam wavelength is 260nm～360nm, average output power is 0～5 watt), and adopted computer-controlled two-dimensional high speed optical scan vibration lens system as the device that can produce the distribution type laser light beam, in therapeutic process, at first shine the dermatosis position through two-dimensional high speed optical scan vibration lens system with super pulse CO 2 laser, make it to form the micropore dot matrix, its degree of depth is controlled at lymphocyte and the hair follicle deep tissue that reaches tegumentary chromatophore and corium, and then use Ultra-Violet Laser to carry out irradiation treatment with same dot matrix distribution, finally reach therapeutic effect.
Beneficial effect of the present invention also is: because native system two bundle light beams of different wavelengths spot sizes are identical, the distribution of pulses position is identical, the light beam easy switching is rapid, therefore can accomplish on a therapeutic equipment, successively to finish two-beam pulse therapy process, this micropore adds the Ultra-Violet Laser irradiation, can reach very high-energy-density with lower laser output power treats, obtain the generation of side effect such as better therapeutic effect and minimizing erythema, vesicle, break through acra type therapy for vitiligo bottleneck.Adopt the present invention to treat following characteristics:
1. the super pulse CO 2 laser treatment of dot matrix can be penetrated and be worn than thick skin, helps Ultra-Violet Laser and enters, and again skin is not had obvious damage, can heal rapidly.
2. the Ultra-Violet Laser penetration depth is limited is the reason that causes different parts difference, penetrates to wear than thick skin through CO2 laser to enter Ultra-Violet Laser again, can significantly improve therapeutic effect.
3. the whole bag of tricks treatment is dissatisfied for the leukodermic curative effect of acra type, and the method treatment acra type vitiligo effect is obvious, and the treatment for other position simultaneously also can obtain better therapeutic and the number of times that shortens treatment.
In apparatus of the present invention, tunable iraser of output (sending) and Ultra-Violet Laser at the same time or separately by super pulse CO 2 laser, adopting this dual-wavelength laser treatment vitiligo will be a kind of Perfected process.And owing to there are two kinds of wavelength lasers to switch output, the selectivity of Therapeutic Method will increase greatly, can adapt to more disease, as simple property lichen (hypertrophic), chronic eczema, alopecia areata, scleroderma, Yin Xiao disease, lymphoma cutis etc.
