激光肺组织轻创伤手术动物实验研究

Animal Experiment Study of Laser Less Invasive Operation for Lung Tissue

为探讨ＣＯ２激光进行肺组织轻创伤手术效果，本实验采用１０只离体猪肺，１００ＷＣＯ２激光进行直接照射；另用１０只杂交犬在全麻、气管插管条件下进行激光照射，初步摸索出激光肺组织轻创伤手术步骤。实验犬饲养３—６个月后处死，肺组织病理，ＨＥ染色，气化形成的空洞，８例空洞消失，２例有由纤维结缔组织增生形成腔壁的空腔。结果ＣＯ２激光肺组织轻创伤手术是一种安全、创伤小的手术，是一种可以融诊断、治疗；融激光直接气化和光化学治疗、光动力治疗为一体的手术。

To study the effect of CO 2 laser less invasive operation,10 lungs drawn from killed pigs were illuminated with 100 W CO 2 laser in this experiment.The lungs of 10 hybrid dogs were also done under general anesthesia.Initial procedures of laser less invasive operation explored.After experimental dogs were raised for 3～6 months,they were killed and then studied pathologically. Result:The lung cavity resulted from gasification reduced or disappeared Conclusion:The result of this study suggest that CO 2 laser invasive operation is a safe one.The operation can be used together with diagnosis and treatment including laser photochemotherapy and photodynamic therapy.
