一种新型 CO_1激光微点显微手术操作器已在耳鼻喉科使用,该设备包括①备有新的红外线光学系统,其与通常使用的显微操作器相比,提供了较小的光斑。近年来于显微喉镜使用的 CO_2激光光斑为0.8至1.2mm,功率为8～10W,但使用于小儿喉科及去除较精微的声带良性病变显得过大。微点显微手术操作器可使光斑直径为0.3～3mm;助术平均为1～2W。②常规的红色氨-氖激光瞄准由非激光的纤维 A new CO 1 laser micro-microsurgery operator has been used in otolaryngology. This equipment includes a new infrared optics system that provides less light spot than the commonly used micromanipulators. In recent years, the use of microlaryngoscope CO 2 laser spot 0.8 to 1.2mm, power 8 ~ 10W, but used in pediatric laryngology and removal of subtle benign vocal cord lesions is too large. Micro-microsurgery operator can make the spot diameter of 0.3 ~ 3mm; assist average 1 ~ 2W. ② Conventional red ammonia - neon laser aiming at non-laser fiber
