CO2 laser lesions were created at varying power densities on the exteriorized canine bladders. A 50-watt carbon dioxide continuous laser coupled to a Zeiss surgical microscope was used. A schematic power curve was developed indexing depth of bladder penetration by the laser against laser energy output. Once the optimal power settings for the carbon dioxide laser were established, vertical heat transmission, hemostasis, and healing were studied. A prototype carbon dioxide laser cystoscope was then constructed that allowed endoscopic delivery of the CO2 laser beam into the intact canine bladder. The beam was focussed by a germanium lens and directed out the end of the endoscope, using a movable mirror. Eight dogs were then endoscopically studied in vivo.
在体外的犬膀胱上以不同的功率密度制作二氧化碳激光损伤。使用了一台与蔡司手术显微镜相连的50瓦二氧化碳连续激光器。绘制了一条示意性功率曲线，以表明激光对膀胱的穿透深度与激光能量输出的关系。确定了二氧化碳激光的最佳功率设置后，对垂直热传递、止血和愈合情况进行了研究。随后制造了一台原型二氧化碳激光膀胱镜，它能够通过内镜将二氧化碳激光束输送到完整的犬膀胱内。激光束由锗透镜聚焦，并通过一个可移动的镜子从内镜末端射出。然后对8只狗进行了体内内镜研究。
