Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a low temperature operation system. Background technique [0002] At present, there are many methods for treating cancer, such as surgical resection, interventional therapy, drug therapy, local ablation therapy and so on. Among them, local ablation therapy is a treatment method that has flourished with the development of various ablation medical devices in the past ten years. Among the local ablation methods, cryoablation has been widely recognized by experts because of its advantages such as large ablation range, multi-knife combination, wide indications, and immunological effects. [0003] The basic principle of cryogenic ablation is to freeze tumor cells to form ice crystals in the cells, destroying the cells and destroying cancerous cells. There are two main types of cryogenic surgery systems currently on the market. One is to absorb a large amount of heat throug...
