Portable low-temperature cryoscalpel

Abstract

The invention relates to the technical field of medical instruments, in particular to a portable low-temperature cryoscalpel. The portable low-temperature cryoscalpel comprises a nozzle, a steel cylinder and a switch mechanism. The portable low-temperature cryoscalpel is characterized in that the mouth of the steel cylinder is connected with the nozzle through the switch mechanism, and the steel cylinder is a detachable steel cylinder. Compared with the prior art, the portable low-temperature cryoscalpel has the advantages that the low-temperature steel cylinder can be independent of other control and spraying units, and different sizes or types of steel cylinders are available; the diameter of the tail end of a flow channel inside the nozzle is 0.03-0.1mm, and different treatment strategies can be worked out through matching between the nozzle and the steel cylinder; in addition, due to the fact that a labyrinth sealing method is adopted between the flow channel and an ejector pin device, leakage of high-pressure low-temperature liquid gas and loss of local cold energy are effectively avoided, the frequency of replacement of the steel cylinder and the frequency of liquid filling are greatly reduced, and treatment cost and maintenance cost are reduced; the portable low-temperature cryoscalpel can be widely used in the fields such as clinic treatment of various dermatoses, skin beauty and pet nursing; the portable low-temperature cryoscalpel is compact and exquisite in structure, simple in operation, and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable cryogenic cold knife. Background technique [0002] Low temperature cryotherapy is a disease treatment method that uses ultra-low temperature freezing to damage and necrosis of diseased tissue. With the continuous development and close integration of medical science and cryotherapy, cryotherapy has been successively applied in various clinical departments, especially in the treatment of skin diseases, which has achieved very ideal results. For problematic skin, such as facial hemangiomas, moles, congenital black marks, brown-green moles, freckles, scars, fleshy warts, granulomas, and alopecia areata, etc., it can not only achieve the purpose of curing, but also has few side effects and no residue. After the scar is healed, the original complexion can be restored faster. Compared with other physical therapy methods for skin diseases, such as laser, microwave, ...

AI Technical Summary

Problems solved by technology

However, the sealing effect of the injection control unit of this product is not good, and there will be more leakage of low-temperature liquid gas, so the frequency of supplementing low-temperature liquid gas and replacing cryogenic containers is relatively high

In addition, the price of this series of products is expensive, which is not conducive to the promotion and use of small and medium-sized hospitals in China
