CO2 lasermedical applications and related matters, for thousands of years, a variety oftreatment methods have been used to improve skin tissue, remove wrinkles,including chemical stripping, erasers. But these methods treatment depth isvery difficult to master, easy to cause damage to the surrounding tissue,postoperative effect is not ideal, there is a lot of disadvantages.
In recentyears, the CO2 laser is used to do beauty, remove aged or damaged skin, and canmake the surrounding tissue is relatively unaffected, the effect issatisfactory. This is widely known as the laser in the skin. CO2 laserwavelength of 10600 nm, which can be absorbed by the water level, and water arethe main components of the soft tissue. When the CO2 laser into the skin, theenergy transfer to organize and absorbed by the organization. The moisture inskin tissue rapid heating, gasification and swelling pressure, break chemicalbonds between the molecules of organization, small molecular mass of a singlemolecule or free out of the organization and to reach the role of grindingepidermis. Grinding depth is less than 100 um, won't harm the deeper tissue.
CO2 laser inthe field of medical application, at present, more and more applied indermatologic surgery. Pulsed CO2 laser can in less than high thermal relaxationtime transmission in the 700 s to 250 mj energy, so that the skin tissuesaccurately gasification and almost leave no scars. It can be used to removefacial wrinkles, moles and scar. Clinical go up also can be used as a scalpel,its clean of the incision, less bleeding.
Can be used ontighten facial skin beauty, such as hair transplantation and scalp is reset inthe operation. CO2 laser is widely used in orthopedic surgery (cut), thoracicsurgery, cardiovascular surgery), brain (meninges tumor, listen to god), entsurgeon, bronchial system and treatment in the vocal cords, oral surgeryresection (tongue and oral cavity), eye (lens), department of gynaecology(cervical cancer, vaginal cancer), plastic surgery (pigment spots, hemangioma,skin cancer), dental (cavities aseptic) uropoiesis surgical department (analand genital cancer), digestive surgery (e., anastomosis of the cecum, the digestivetract cut), general surgery (breast cancer, tumor excision, skin grafts).
CO2 laser isused in the treatment of facial wrinkles, long as lips lip weeks of radiation(including labial red and a pile of wrinkles), canthus canthus wrinkles), browand forehead, cheeks and chin. It to the improvement of the skin wrinkle depthof about 50% on average, the effect is obvious. Additional CO2 laser can beeffectively used to uplift the scar repair, removal of tattoo, in treatment ofsome benign skin tumor, hypertrophy of rosacea, etc. CO2 laser operator workthere are two main ways: continuous wave (the CW) and pulse mode (such as giantpulse, the pulse type). In the CW this way, the laser continuous laser energy,is after the foot switch is depressed, this approach USES a high average powermode of operation, is a precision limited surgical operation way, the mainlanguage activation or gasification muscle tissue, damage degree of surroundingtissue is small.
Pulsed CO2laser pulse width is 200 ~ 1000 s, it was used in control precision highertechnology. First a so-called ultra pulse CO2 laser is used to demand highersurgery, such as skin beauty culture. CO2 laser, makes skin cosmetic surgeryaccurate, easy to control, it can obviously improve the look of the skin, makethe person look young. At the same time, laser therapy for beauty is still avery new technology, to further improve and develop, accumulate moreexperience. So far, the effect of the surgery in patients undergoing of CO2laser cosmetic is generally satisfactory.
