Abstract

The invention discloses a low temperature device. The low temperature device comprises a low temperature container, a catheter, a one-way valve and a puncturing needle assembly. The catheter is connected between the low temperature container and the puncturing needle assembly. The one-way valve is arranged at the middle section of the catheter. The low temperature device can be punctured into a tissue needing to be frozen, then freezing media are output through an output hole, and freezing is completed; in the puncturing process, excessively-early jetting of the freezing media can be effectively avoided, and waste can be avoided; after puncturing is completed, the catheter is lifted, the output hole is exposed accordingly, the freezing media are output to directly act on the lesion position, and waste is avoided; meanwhile, the input amount can be easily controlled, and healthy tissues can be prevented from being injured.

Description

technical field [0001] The utility model relates to a low temperature device. Background technique [0002] Cryosurgery and cryosurgery are procedures that usually involve freezing tissue in order to destroy that tissue. Cryosurgery and cryotherapy can be used to treat a variety of medical conditions. The ultimate goal of such procedures is only to destroy abnormal tissue. Does not damage healthy tissue. [0003] In the prior art, it generally includes contact freezing and spray freezing, but these two freezing methods have a large divergent area, so they will cause certain damage to healthy tissues, and at the same time, it is easy to waste freezing medium. Contents of the invention [0004] The technical problem to be solved by the utility model is to provide a low-temperature device, which can penetrate into the tissue that needs to be frozen, and then complete the output of the freezing medium through the output hole to complete the freezing, and can effectively avoid...
