由于CO_2激光的红外波长是被水吸收的,而生物组织含大量的水,故能用CO_2激光做手术.采用由镜片传光的显微操作系统的专用显微装置,可以完成精密外科手术.我们的喉科在1971年开始进行临床研究.此后,在我们科和全世界都作了几千例手术.临床适应症是良性肿瘤尤其是喉部乳头状瘤和声带上的小恶性肿瘤.以后应用范围又扩展到癌前期病变和口腔、鼻咽部和喉咽部小的恶性肿瘤.专用的气管镜也能治疗气管肿瘤.在气道和消化道范围内还有若干其他的应用.一般是用5至25瓦的连续波CO_2激光器,光斑面积1～2毫米.这种
Since CO 2 laser’s infrared wavelength is absorbed by water, and the biological tissue contains a lot of water, it can be operated by CO 2 laser.Using microscopy operating system by the lens transmission microscope can perform precision surgery. Our throat department started clinical studies in 1971. Thousands of surgeries have since been performed in our department and throughout the world.Clinical indications are benign tumors, especially small laryngeal papilloma and vocal cord malignancies. The range of applications extends to precancerous lesions and small cancers in the mouth, nasopharynx, and hypopharynx. A specialized bronchoscope can also treat tracheal tumors. There are several other applications within the airway and digestive tract. With 5 to 25 watts of continuous wave CO_2 laser, the spot area of 1 to 2 mm
