国内1975年开始应用激光治疗宫颈糜烂。这是利用激光的热效应、冲击波和电磁波效应以及光化学效应使组织细胞失活和蛋白质变性,进而发生凝固性坏死、炭化和气化。我院采用上海注射器三厂生产的YYJG1-A 型二氧化碳激光治疗机(波长10.6μ,射束直径1mm,输出功率30w,工作电流10～15mA)以光斑和聚焦两种刀头治疗宫颈糜烂,自1981年5月至1982年4月共治疗178例。现将随访3～6个月资料完整的139例报告如下。
Domestic application of laser treatment of cervical erosion in 1975. This is the use of laser thermal effects, shock waves and electromagnetic effects and photochemical effects of tissue cells inactivation and protein denaturation, and then coagulation necrosis, carbonization and gasification. Our hospital adopts the YYJG1-A carbon dioxide laser treatment machine (wavelength 10.6μ, beam diameter 1mm, output power 30w, working current 10 ~ 15mA) manufactured by Shanghai Syringe Factory No. 3 to treat cervical erosion with both spot and focus From May 1981 to April 1982 a total of 178 cases were treated. Now follow-up 3 to 6 months data complete 139 cases are as follows.
