自1967年美国光气激光器研究室试制成功手术CO_2激光器以来,人们很快就发现激光器可以在内腔镜中使用。1968年试制成功内腔镜激光器模型,并在狗的声带上进行实验研究,在实验研究过程中,激光器充份显示了其优越性。1971年为了使激光手术能够达到更加准确、精细的程度,在激光器上又附加了手术显微镜的部件,广泛地应用于鼻、口腔、咽、喉、气管病变。早期的内腔镜激光器是将标准的Jackson-Pilling通气支气管镜(5mm,30cm)装配上原始的激光系统,并将可见光束在镜端聚焦成2mm直径的指示光点,用拇指螺旋对激光光束和指示光点进行同步调节。但这种原始激光系统比较笨
Since the successful manufacture of a surgical CO 2 laser in the United States in 1967, it has been found that lasers can be used in endoscopic applications. In 1968, the laser model of endoscopic laser was successfully manufactured and experimentally studied on the dog’s vocal cords. During the experiment, the laser showed its superiority. In 1971 in order to laser surgery can achieve more accurate, sophisticated degree, attached to the laser surgical microscope components, widely used in nose, mouth, pharynx, larynx, tracheal lesions. Early endoscopic lasers were fitted with a standard Jackson-Pilling bronchoscope (5mm, 30cm) on the original laser system and the visible light beam was focused on the mirror end into a 2mm diameter indicating spot. The thumb helix was used to illuminate the laser beam And instructions light spot synchronization adjustment. But this primitive laser system is stupid
