从动物实验看到兔皮耳部以便携式低功率CO_2激光器3W,聚焦汽化10、20s,其破坏深度可达1～1.5mm,兔背部用5W,聚焦汽化10、20与40s,其破坏深度可分别达2.5～8mm。在此基础上,以低功率CO_2激光汽化破坏组织深度相应的条件下,治疗外阴多种病变27例。结果看到,只要激光聚焦模式好,操作适当,持续汽化时间足够,低功率CO_2激光治疗外阴病变可达彻底汽化,甚至切除相应病灶。安全简便、疗效可靠。 Animal experiments showed that rabbit ears with portable low-power CO 2 laser 3W, focused vaporization 10,20s, the destruction depth of up to 1 ~ 1.5mm, rabbit back with 5W, focused vaporization 10,20 and 40s, the depth of destruction can be Respectively, up to 2.5 ~ 8mm. On this basis, with the low-power CO_2 laser vaporization under the conditions of tissue damage corresponding to the treatment of a variety of lesions of the vulva in 27 cases. The results showed that, as long as the laser focus mode is good, proper operation, sustained vaporization time is sufficient, low-power CO_2 laser treatment of genital lesions up to complete vaporization, and even removed the corresponding lesion. Safe and easy, effective and reliable.
