CO_2激光刀功率密度高,细光束切割组织损伤少,有热凝固效应,对创面有止血和灭菌作用,并能刺激修复性再生过程。用CO_2激光刀治疗口腔肿瘤22例:龈瘤12,纤维瘤4,乳头状瘤5,纤维瘤病1。治疗面颈部肿瘤26例:基底细胞癌3,血管瘤9,皮角14。肿瘤直径0.2～20mm。治疗顽固的拔牙后出血5例。共53例患者,年龄35～55岁。传导麻醉和浸润麻醉,在健康组织边界作切口,用聚焦光束切割组织,同时凝固创缘和创面。CO_2激光波长10.6μm,连续作用光导输出最大功率20～40W。切除肿瘤后用散焦光束处理肿瘤床,薄薄撒上一层三溴酚铋粉,使形成致密的薄膜,此膜的重要特性是:形成强有力的屏障,阻止细菌、病毒和瘤细胞进入组织,防止
CO_2 laser knife high power density, thin beam cutting less tissue damage, thermal coagulation effect on the wound bleeding and sterilization, and can stimulate the repair of the regeneration process. 22 cases of oral tumor treated with CO2 laser knife: gingival tumor 12, fibroma 4, papilloma 5, fibromatosis 1. Treatment of 26 cases of facial and cervical tumors: basal cell carcinoma 3, hemangioma 9, skin angle 14. Tumor diameter 0.2 ~ 20mm. Treating stubborn tooth bleeding in 5 cases. A total of 53 patients, aged 35 to 55 years. Conducting anesthesia and infiltration anesthesia, making incisions at the boundaries of healthy tissue, cutting the tissue with a focused beam of light, and simultaneously coagulating wounds and wounds. CO_2 laser wavelength of 10.6μm, continuous light output maximum power output of 20 ~ 40W. The tumor is treated with a defocused beam after the tumor has been removed and a thin layer of bismuth tribromide powder sprinkled to form a dense film with the important properties of forming a strong barrier that prevents the entry of bacteria, viruses and tumor cells Organize, prevent
