Abstract

The invention provides a pre-cooling device for cryoablation and a cryotherapy system. The device comprises an air inlet interface, at least two ventilation branches and a single-stage compression self-cascade refrigeration system component, and the air inlet interface communicates to the air inlet ends of the at least two ventilation branches. According to the pre-cooling device and the cryotherapy system, the at least two stages of refrigerating cycle condensation evaporators or evaporators are used during re-cooling to pre-cool air in one ventilation branch, and the pre-cooling efficiency is effectively improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a precooling device and a cryotherapy system for cryoablation. Background technique [0002] As a minimally invasive targeted surgery, cryoablation has the characteristics of less trauma, less toxic and side effects, and definite curative effect. It also has the advantages of clear boundary of ablation ice ball, participation in activation of tumor immune function, no damage to large blood vessels, and no obvious pain. Ultra-low temperature targeted freezing and hyperthermia become a reality. In recent years, cryosurgery has been widely used in the treatment of metastatic liver cancer, prostate cancer, kidney cancer and so on. Among them, argon gas may be used, and nitrogen gas at room temperature and high pressure of, for example, 5 to 10 MPa may be used as the surgical working gas. [0003] In the patents with publication numbers CN107951558A and CN106420039 A, in order to realize the mul...
