外科切除癌肿往往在原发部位出现肿瘤复发。二氧化碳激光能精确地进行外科切除,同时能封闭小动脉、静脉和淋巴管.二氧化碳激光能汽化和瞬间蒸发细胞内的水分,完全破坏肿瘤细胞(包括细菌).此外,激光外科是非接触性外科,避免外科器械污染消毒部位。二氧化碳激光外科这些特性对癌肿外科是有利的.本文目的是研究激光外科对局 Surgical resection of cancer often occurs at the site of primary tumor recurrence. The CO2 laser can accurately perform surgical resection and at the same time it can close small arteries, veins, and lymphatic vessels. The CO2 laser vaporizes and instantly evaporates intracellular water, completely destroying tumor cells (including bacteria). In addition, laser surgery is a non-contact surgery. Avoid surgical instruments that contaminate the disinfection site. These features of carbon dioxide laser surgery are beneficial for cancer surgery. The purpose of this article is to study the laser surgery game.
