Treatment device based on laser with wavelength of 940 nm

Abstract

The invention discloses a treatment device based on laser with wavelength of 940 nm. The treatment device is characterized by comprising a laser device, a cooling system and a probe handle, wherein the laser device is used for emitting the laser with the wavelength of 940 nm and is connected with the probe handle through a transmission optical fiber; the cooling system is used for providing a cooling working medium and is connected with the probe handle through a cooling working medium conveying pipeline; the laser with the wavelength of 940 nm emitted by the laser device has relatively good tissue penetrability; absorption of hemoglobin to the laser is increased, absorption of melanin and the like to the laser is reduced, treatment of vascular skin diseases such as fat and thick type port-wine stains with relatively large lesion blood vessels and face angiotelectasis with relatively small lesion blood vessels is realized, and the treatment device is relatively good in treatment effectand relatively good in universality; and meanwhile, a mode of coupling refrigerant surface spray cooling with cold air cooling is adopted, so that thermal injury to epidermis and dermis is effectively avoided.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a therapeutic device based on 940nm wavelength laser. Background technique [0002] Vascular skin diseases are caused by vascular malformations in the skin. They mostly occur on exposed parts such as the face and neck, mainly including port wine stains, hemangiomas, facial telangiectasias, and varicose veins, which seriously affect the physical and mental health of patients. [0003] The existing laser treatment of vascular skin diseases is based on the "selective photothermal effect". Under the premise of not damaging the surrounding normal tissues, the purpose of selectively damaging blood vessels of diseased tissues is achieved. [0004] Currently, 585nm / 595nm Pulsed Dye Laser (PDL) is mainly used for treatment. However, due to its limited tissue penetration depth and prone to side effects such as purpura, it is suitable for the treatment of shallow buried blood vessels and sm...
