Treatment theory: The new 1470nm semiconductor laser scatters less light into the tissue, distributing it evenly and effectively. The tissue absorption rate is strong and the penetration depth is shallow. coagulation.The scope is concentrated and does not damage surrounding healthy tissue. It has high focusing efficiency and can be transmitted through optical fiber. It can be absorbed by hemoglobin and cell water. By concentrating heat on a small amount of tissue, it can rapidly vaporize and decompose the tissue, resulting in less heat damage and the effect of coagulation and hemostasis. Advantages: Best suited for minimally invasive surgeries such as repair of nerves, blood vessels, skin and other small tissues, and varicose veins. Optimal degree of water absorption in tissue at a wavelength of 1470 nm. The wavelength has a high level of water absorption in tissues and 980 nm provides high absorption in hemoglobin. The biophysical properties of the waves used in dual wave…
