Separated low-temperature tumor therapeutical equipments

Abstract

The utility model relates to a separate low-temperature therapeutic apparatus for tumors, which belongs to the field of low-temperature medical equipment. The invention includes: a low temperature treatment section, a vacuum heat insulation section, a handle assembly and a liquid inlet pipe assembly, these four parts are all separate assemblies and are connected by threads. The low temperature treatment section includes a head diffuser and thermocouple made of pure copper. The vacuum insulation section includes a ring plug, a vacuum inner tube, a vacuum outer tube, the left end cover of the vacuum chamber, the shell of the vacuum chamber, and the right end cover of the vacuum chamber. The handle assembly includes an outlet Air pipe main pipe, handle left end cover, handle shell, heat insulation material, handle right end cover, air outlet branch pipe, liquid inlet pipe assembly includes: liquid inlet pipe, PTFE positioning block, sealing ring, liquid inlet pipe gasket and liquid inlet Tube fastening nut. The invention can realize the one-time use of the probe head, and the vacuum insulation section can be used repeatedly, which greatly reduces the operation cost and maintenance cost. One vacuum insulation section can be used in conjunction with multiple types of head diffusers, and can be adapted to different sizes , location and nature of the tumor.

Description

technical field [0001] The invention relates to a tumor cryotherapy instrument, in particular to a separate type tumor cryotherapy instrument, which belongs to the field of low temperature medical equipment. Background technique [0002] Cryosurgery is a clinical science that uses ultra-low temperature freezing to cause tissue damage and necrosis. Compared with traditional tumor treatment surgery, cryosurgery has the advantages of less side effects, no dose limitation, lower treatment cost, and less pain to patients, and can prevent the spread of cancer cells, and has the functions of stopping bleeding and reducing bleeding. effect. Cryosurgery often relies on the development of cryogenic instruments. For cryotherapy of tumors in vivo, deep penetrating probes are mostly used. It can be divided into open and closed probes. The head of the open probe is open, and after being inserted into the tissue, the probe is sealed by coagulation of the tissue at the front end. This m...

AI Technical Summary

Problems solved by technology

Due to the existence of the vacuum structure, the cost of the probe is relatively expensive, and it is difficult to achieve one-time use, which may lead to cross-infection between patients, thus requiring strict disinfection procedures
