摘要
本文重点研究激光凝固离体癌肿组织的最佳功率和最佳时间。方法：在动物实验的基础上，利用实时超声引导，观察间质激光凝固离体肝癌组织标本。结果：激光能有效损伤癌肿组织造成凝固性坏化，效果肯定，功率为６瓦，时间为８－１０分钟时癌组织凝固效果最佳，损伤范围直径２．８ｃｍ左右。结论激光凝固离体癌组织的最佳功率和最佳时间分别为６瓦及８－１０分钟。
The paper was designed to study the best time and power of laoer photocoagulation on tumorous tissues. Methods:On the basis of animal experiment,s we Rave uslielized zeatime a ulszasound guided iutecsfiral larer photo-coagularion on in vitro samples of hepatocarcinoma ficcues.Resercould effechiuely danage fumezouo fissues that in duce coagulafiue necrosis. The lest offects were abserued when ul-frasound power was six watt and duraxon was 8 - 10 minutes, while its range of damage was about 2. 8cm. Conclusim: The leas power and time of lasei coagnlation on fuworous fissues were respecfiuely 6 waff and 8 - 10 minutes.
