激光是六十年代出现的新技术,到了七十年代,光纤技术与激光技术相结合成为能够实现激光用于人体脏器的腔内治疗,这是激光医疗上的一项重大突破。天津日报88年3月2日报导了天津医学院第一附属医院胃镜室用激光粉碎了两个鸭旦大的胃石,宣告天津市的第一例激光治疗胃石成功。在此病例中,采用的是航天工业部三院八三五八所研制的YAG双频激光光纤治疗仪。这种设备能使高功率的YAG激光在纤细而柔软的光导纤维中传播,从而使原来主要作为诊断手段的
Laser was a new technology emerged in the 1960s. By the 1970s, the combination of optical fiber technology and laser technology became an important breakthrough in laser medical treatment. Tianjin Daily reported on March 2, 1988 that the First Affiliated Hospital of Tianjin Medical College, a gastroscope room, smashed two large duck stomach stones, declaring the first laser treatment of stomach stone in Tianjin. In this case, YAG dual-band laser fiber optic therapeutic apparatus developed by No. 8,358 Institute of Aerospace Industry was used. This device enables the high-power YAG laser to propagate in the slender and soft optical fiber, so that the original mainly as a diagnostic tool
