Laser CO2.. A combination of carbon dioxide, nitrogen and helium gases. Dermatology, Cosmetic and General Surgery

Laser - CO2:
Carbon dioxide (CO2) is the most common and effective means of skin, cosmetic and general surgery. The medium in this type of laser is a mixture of carbon dioxide, nitrogen, and helium gases, usually raised or irritated by direct electrical current.
The CO2 laser allows the continuous beam pack on the longest wave (10600 nanometers), in the average portion of the infrared spectrum of the electromagnetic spectrum. The CO2 laser beam is invisible, so the visible beam of low-impact helium neon is used to guide the laser to precisely the spot to be processed to direct the beam to the desired target.
Laser light passes through the multi-jointed arm and concentrated lenses.
The target tissue for this type of laser is water, since light is absorbed by the biological tissues causing damage by rapid heating and evaporation of water inside the cells. The strong absorption of laser light by the water occurs in the tissue damage (what you see during the process is the effect it gets on the human weave afterwards). The power output of the laser light exceeds 100 watts in continuous operation and 50 watts when using the pulsing process.
The factors influencing tissue degradation by laser are: the amount of bonding ability of the tissue, the size of the spot, and the time of thermal regression (the time between laser tissue heating and re-cooling).
The CO2 laser is currently provided with computer hardware that makes it safer and more user-friendly. These devices are programmed in a simpler way to use either for skin peeling, surgical cutting or removal of the surface layer of the skin. The surgeon should only use the information stored on these computers according to the condition he is handling, since the laser power and spot size are all automatically adjusted.
