连续CO_2激光最近已被推荐为外科器械。精确、几乎是无血的组织切除已成功了,而且术后无疼痛、水肿或疤痕,激光最早在治疗口腔、咽喉部方面的评价早已描述过。CO_2激光1965年连续CO_2激光被推荐了,这种产生能量的光在一定的波长能更好地被水也可以被生物组织所吸收(10.6μM)(Hall etal,1971 a,b),因为这些光不是脉冲的,所以能更精确地控制切除组织。相干系统400CO_2激光在最近二年内已应用于Southampton.这个连续激光刀已经 Continuous CO2 laser has recently been recommended as a surgical instrument. Accurate, almost bloodless tissue resection has been successful, and postoperative pain, edema or scarring, laser earliest in the treatment of oral and throat evaluation has long been described. CO 2 laser In 1965, a continuous CO 2 laser was proposed. This energy-producing light is better absorbed by biological tissues (10.6 μM) at a certain wavelength (Hall et al, 1971 a, b) because these The light is not pulsed, so the removal of tissue can be controlled more precisely. The coherent system 400 CO2 laser has been used in Southampton for the last two years. The continuous laser knife has been
