CO₂ ultra-pulse laser is a laser beam produced by electrically excited carbon dioxide gas molecules, with a wavelength of 10.6 microns, which is mid-infrared light. It has the characteristics of pure monochromaticity, strong directionality, high brightness, good coherence and strong electromagnetic wave, etc. It has the combined effect of light, heat, pressure and electromagnetic factors on the biological organism. When irradiating the acupuncture point with low power density of CO₂ laser, it produces thermal effect on human tissue. I. Principle of CO₂ super pulse laser The CO₂ laser therapy instrument adopts the sealed-away CO₂ laser, whose output laser is transmitted by the light-guiding joint arm, characterized by high energy density and good directionality, which is invisible far-infrared light. When the laser beam is output by the focusing mirror, the high temperature generated by the focusing point can vaporize the target tissue, which can be used for cutting, cautery and coagulation surgery. Advantages of CO₂ super pulse laser 1.Little damage, avoiding the shortcomings of ordinary continuous CO₂ laser which can damage the surrounding normal tissues, produce crust and wound healing, etc. The clinical healing process is not significantly different or even faster compared with conventional surgical methods. 2.Less bleeding, because the bleeding is stopped at the same time of incision, so there is almost no bleeding during the whole operation. It can provide bloodless vision for fine surgery. 3.Short operation time, eliminating the trouble of hemostasis, and the wound does not need to be sutured, saving a lot of operation time. 4.Less postoperative complications, very few hematomas and petechiae appear after surgery, quick recovery, less impact on work and life, more easily accepted by patients. Indications of CO₂ super pulse laser Pigmented nevus, common wart, steamed wart, acute warts, freckles, corns, hemorrhoids, hemangioma, dermatofibroma, granuloma, basal cell carcinoma and other skin tumors, etc. Four, CO₂ super pulse laser treatment before and after comparison FAQ 1, what are the side effects after treatment? There are no special side effects. There may be some swelling after the treatment, which can be dissolved naturally. 2.Preparation before treatment? (1) The affected area should not have any kind of inflammation. (2) Treatment is prohibited during pregnancy and menstruation. (3) Clean the affected area, just wash it with water, no residual cosmetics. 3.How do I need to take care of it after treatment? (1) Keep the wound surface dry and clean after receiving treatment. (2) After treatment, because the skin is relatively delicate to prevent sun exposure. (3) Women should avoid menstruation and breast-feeding period. 4.Effects of CO₂ ultra-pulse laser treatment? CO₂ ultra-pulsed laser treatment technology is a safe and effective treatment method, which makes your skin free of discomfort such as burning and stinging, pins and needles or peeling, no redness and swelling after the operation, and zero infection throughout the treatment.
