Equipment for treating vitligo by utilizing turnable lattice dual wavelength laser

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 [0001] The invention relates to laser treatment equipment for skin diseases such as vitiligo. It is especially suitable for treating acral vitiligo. It has both ultraviolet laser and infrared laser output, and is also suitable for chronic lichen simplex (hypertrophic type), psoriasis, and chronic eczema. , Alopecia areata, scleroderma, skin lymphoma and other diseases. Background technique [0002] Vitiligo (Vitiligo) is a common depigmentation skin disease with an incidence rate of 0.5% to 2%. At present, the number of patients in the country is about 20 million. Its etiology and pathogenesis have not yet been determined, and it is a worldwide treatment problem. Among them, it is the most difficult to treat the acral type distributed in the hands, feet, fingers, toes and other parts. At present, the medicines for the treatment of vitiligo in the domestic market cannot reach a good curative effect. [0003] In recent years, ultraviolet laser has achieved goo...

Problems solved by technology

[0005] In order to solve the poor penetration of ultraviolet laser, it can only penetrate to about 50 μm on the skin surface, which cannot reach the irradiation depth required for treatment. For the problem of less than therapeutic effect, we use ultra-pulse CO2 laser as another treatment light source, because the laser beam generated by ultra-pulse CO2 laser is an infrared laser beam with tunable pulse width, peak power and pulse frequency with a wavelength of 10.6 microns , so it is not only suitable for skin tissue absorption, but also can form micropores with controllable depth when used on the skin surface, so that the skin can be reduced when treating acral vitiligo and vitiligo lesions on the skin and wrinkles. thickness, so that the ultraviolet laser can act on epidermal pigment cells, dermal lymphocytes and deep tissues of hair follicles to achieve therapeutic effects
