一、概述随着我国医学科学的迅速发展,低温技术在医疗上的应用也日趋广泛,并逐步形成一门专科“冷冻外科”。液氮低温治疗机是用液氮作致冷剂的,最低温度可达-196℃。用它可治疗一些表浅的良性和恶性肿瘤、炎症及一些赘生物,如皮肤癌、血管瘤、淋巴管炎、慢性鼻炎、宫颈炎、鼻出血、寻常疣、痔核等;用于辅助手术能使切除部位的血液暂时凝固,使出血减少,手术时间缩短,如
First, an overview With the rapid development of medical science in China, the application of cryogenic technology in the medical field is also becoming more and more widespread, and gradually formed a specialist in “frozen surgery.” Liquid nitrogen cryogenic treatment machine is used for liquid nitrogen refrigerant, the lowest temperature up to -196 ℃. It can be used to treat some of the superficial benign and malignant tumors, inflammation and some neoplasms, such as skin cancer, hemangioma, lymphangitis, chronic rhinitis, cervicitis, epistaxis, verruca vulgaris, hemorrhoids, etc .; for surgery So that the temporary removal of blood coagulation site, so that bleeding is reduced, the operation time is shortened, such as
