冷冻医疗是低温技术领域中十分引人注目和极有发展前途的一个分支,六十年代以来,已取得相当丰硕的成果。本文除了总结冷冻医疗的特点外,并对低温手术器械的要求,制冷原理和适用的对象作了简要的阐述。另外对所采用的工质和制冷剂作了比较、分析和说明,以及对新的低温技术——热管应用于低温手术器械的结构原理和活组识检查仪的应用特点及其构造要求作了扼要的介绍。
Cryotherapy is a very attractive and promising branch of cryogenic technology that has yielded fruitful results since the 1960s. In addition to summarizing the characteristics of frozen medical treatment, this article also briefly describes the requirements of cryogenic surgical instruments, cooling principle and applicable objects. In addition, the working fluids and refrigerants used are compared, analyzed and explained, as well as the application of the new cryogenic technology - the principle of the heat pipe used in cryogenic surgical instruments and the application features of the living tissue inspection instrument and its structural requirements A brief introduction.
