根据不同作者报导,在同一功率 CO_2激光的切割作用,脉冲波比连续波为好,对切缘组织损伤亦小。但没有足够的实验数据给以证明。本文用脉冲波和连续波对切下的新鲜腭扁桃体和骨骼肌进行研究,对热损伤的深度作细致测量。作者用能释放连续波和脉冲波的 CO_2激光装置(脉冲波参数:波峰功率250W,脉冲时间0.1～0.9毫秒,10～990次/秒)对58只腭扁桃体和胸锁乳突肌用各种参数作切割试验。

According to different authors, in the same power CO2 laser cutting, the pulse wave is better than the continuous wave and the damage to the cutting edge tissue is also small. But there is not enough experimental data to prove. In this paper, pulsed and continuous wave cut fresh palate tonsils and skeletal muscle were studied, the depth of thermal damage made detailed measurements. The authors used a CO2 laser device capable of releasing continuous wave and pulsed waves (pulse wave parameters: wave power 250W, pulse time 0.1-0.9 ms, 10-990 beats / second) on 58 palatine tonsils and sternocleidomastoid muscle using various Parameters for cutting test.
