作者等报告1980年以来在导光纤维内窥镜下应用 Nd:YAG(钕:钇铝石榴百)激光治疗58例气管疾病。手术以疏通气道、改善呼吸及急救止血和根治肿瘤等为目的。手术时激光器导光石英纤维外套2mm 外径的硅橡胶管,尖端输出功率为100W 以上,照射时间为60秒的连续照射或0.1秒的间断照射。Nd:YAG 激光波长1.06μm,近似红外线,几乎不被水吸收、透过或扩散,比CO_2激光的组织传导性好,可产生广泛的热凝
The authors report that 58 cases of tracheal diseases were treated with Nd: YAG (Neodymium: Yttrium Aluminum Pomegranate 100) laser under guided light fiber endoscope since 1980. Surgery to clear the airway, improve respiration and emergency stop bleeding and cure the tumor for the purpose. Surgery laser guide quartz fiber jacket 2mm diameter silicone rubber tube, the tip output power of 100W or more, the irradiation time of 60 seconds of continuous irradiation or 0.1 seconds of intermittent irradiation. The Nd: YAG laser has a wavelength of 1.06 μm, which is approximately infrared and hardly absorbed, transmitted or diffused by water and is more conductive than the tissue of the CO 2 laser and produces extensive thermal coagulation
