摘要
介绍了一种新型的激光冠状动脉成形术系统，该系统由CO激光和可操作的血管镜组成。一氧化碳激光器因其汽化能力强、传输光纤灵活等特点而被用作治疗激光。医用CO激光设备的波长可达5um，是一种新型的医用CO激光设备。直径为1.8 m m，长度为0.9 m的可操作血管镜导管实现了激光照射和腔内诊断的精确定位。该控制系统防止了激光辐照和光纤热破坏。
New laser coronary angioplasty system using manipulatable angioscope and co laser with infrared glass fiber
A new laser coronary angloplasty system using CO laser and a manipulatable angloscope was described. CO laser was employed as therapy laser due t o its strong vaporization capabi l i ty and f lex ib le f iber dellvery characteristics. The medical CO laser equipment wh ich emi t ted 5um in w a v e l e n g t h w a s d e v e l o p e d . The manipulatable angioscope catheter of which dlmenslons were 1.8 m m In dlameter and 0.9 m in length realized precise targeting of laser irradlation and intraluminal diagnosis. The cont ro l sys tem prevented fa i lu re laser irradiation, and fiber thermal destructlon.
