Liquid nitrogen treatment auxiliary device for the general surgery department

Abstract

The invention discloses a liquid nitrogen treatment auxiliary device for the general surgery department. The liquid nitrogen treatment auxiliary device comprises a liquid nitrogen cylinder, external threads of an upper end bottle opening of the liquid nitrogen cylinder are in threaded connection with internal threads of a cylinder cover; a circular hole is formed in the center of the upper end ofthe cylinder cover; a conduit is arranged in the center of the inner wall of the upper end of the cylinder cover; the bottom end of a guide pipe extends into the liquid nitrogen cylinder; the invention discloses the liquid nitrogen treatment auxiliary device for the general surgery department, which has the advantages of simple structure, and convenient mounting, dismounting and use, great convenience is brought to the use of a user; moreover, the device can be used as required, under the irradiation positioning of an electronic laser lamp, rapid positioning and fixing of a treatment part arerealized through a positioning and fixing device; a cryogenic head is rapidly pushed through a pushing device, so that the cryogenic head is accurately pushed to the treatment part, the situation of erroneous spraying caused by unstable fixation or inaccurate positioning is avoided, the workload of medical staff is reduced, the cryogenic treatment quality is guaranteed, and the use efficiency of the liquid nitrogen treatment auxiliary device is improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a liquid nitrogen treatment auxiliary device for general surgery. Background technique [0002] Liquid nitrogen cryotherapy is a kind of physical therapy commonly used in hospital dermatology and beauty salons. It uses low temperature to act on diseased tissues to cause necrosis and shedding of diseased tissues, so as to achieve the purpose of beauty treatment. The refrigerant used in frozen beauty treatment is liquid nitrogen. It is a colorless, odorless, non-flammable, non-explosive, transparent liquid with a temperature of about -196°C. The main mechanism of its beauty treatment is a sudden drop in temperature, which causes ice crystals to form inside and outside the tissue cells, and the structure is destroyed and cracked. Low temperature dehydrates cells, concentrates electrolytes, changes pH, denatures proteins, and dies due to cell metabolism. Using thi...

[0002] Liquid nitrogen cryotherapy is a kind of physical therapy commonly used in hospital dermatology and beauty salons. It uses low temperature to act on diseased tissues to cause necrosis and shedding of diseased tissues, so as to achieve the purpose of beauty treatment. The refrigerant used in frozen beauty treatment is liquid nitrogen. It is a colorless, odorless, non-flammable, non-explosive, transparent liquid with a temperature of about -196°C. The main mechanism of its beauty treatment is a sudden drop in temperature, which causes ice crystals to form inside and outside the tissue cells, and the structure is destroyed and cracked. Low temperature dehydrates cells, concentrates electrolytes, changes pH, denatures proteins, and dies due to cell metabolism. Using this principle, freezes the vegetation that hinders skin beauty, such as freckles, moles, and pigmented spots, so that its tissue cells Denatured necrosis falls off to achieve the purpose of treatment and beauty, but the structure of traditional liquid nitrogen treatment equipment is too simple, lacks corresponding auxiliary devices to support, and is inconvenient to install and disassemble, which brings great trouble to users. Realize rapid positioning and fixing of the treatment part according to the demand, the position of the freezing head remains unchanged, and the rapid advancement of the freezing head cannot be realized, so that the freezing head cannot be accurately pushed to the treatment site, and the occurrence of mis-spraying due to fixation or unstable positioning cannot be avoided. , virtually increases the workload of medical staff, and the quality of cryotherapy is difficult to be guaranteed, resulting in low efficiency of the use of liquid nitrogen therapy auxiliary devices. Therefore, the realization of a general surgical liquid nitrogen therapy auxiliary device that can solve such problems is imperative Row
