This experiment investigates CO2-laser-induced histological effects on fallopian tubes obtained during hysterectomies in women. Tubal transversal sections were performed at isthmic and ampullar sites. Forty strips were available for histological study of the cut section area. The role of different parameters such as radiation power and beam fractionation (continuous versus pulsed) on tissue lesions was assessed. In tubal microsurgery, the CO2 laser can be used as a scalpel with the predominant advantage of minimal tissular alterations. As a result of this study, our recommended parameters are the following: radiation power, 7-10 W; beam focalization zone, 0.2 mm; energy density, 20,000-35,000 W/cm2; continuous operation; moving speed, 1 cm/s.
本实验研究二氧化碳激光对女性子宫切除术中获取的输卵管产生的组织学影响。在输卵管峡部和壶腹部进行横向切片。有40条切片可用于对切面区域进行组织学研究。评估了诸如辐射功率和光束分束（连续与脉冲）等不同参数对组织损伤的作用。在输卵管显微手术中，二氧化碳激光可用作手术刀，其主要优点是对组织的改变最小。作为本研究的结果，我们推荐的参数如下：辐射功率7 - 10瓦；光束聚焦区0.2毫米；能量密度20,000 - 35,000瓦/平方厘米；连续操作；移动速度1厘米/秒。
