Liquid nitrogen auxiliary therapy device for general surgery department

Abstract

The invention discloses a liquid nitrogen auxiliary therapy device for the general surgery department, and relates to the technical field of medical apparatuses. The device comprises a main shaft rodin the middle; a coating liquid protection device is installed on an installing disc; an adjusting device is installed on the main shaft rod; a bearing disc is installed on a power device; the coatingliquid protection device comprises an annular liquid supply hose and an annular liquid return hose; liquid outlet pipes are installed in all installing holes; back-drawing pipes are slidably installed in all through holes; the adjusting device comprises a control rod; a C-shaped slide block slidably sleeves the main shaft rod; locating rods are uniformly and rotatably connected to the outer sideface of the slide block in the annular direction; the power device comprises a C-shaped support; a driving motor is installed at the front portion of the lower end of a handle. The device has the advantages that liquid nitrogen can be quickly and uniformly smeared, redundant liquid nitrogen can be timely recycled, the harm of liquid nitrogen is reduced, and the device is convenient to operate andhigh in safety.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] In the treatment of general surgery, when some hyperplastic or diseased tissues of the human body are treated, liquid nitrogen cryotherapy is sometimes used to freeze diseased cells and good tissue cells in a small area to death by using the low temperature of liquid nitrogen, so that eventually fall off. Generally, when liquid nitrogen is used for treatment, the medical staff use cotton swabs to smear the diseased tissue comprehensively. Due to the lack of protective measures and the irreversible damage of liquid nitrogen, in order to prevent excessive damage to the surrounding good tissues, the application is very careful and slow. Only a small amount of liquid nitrogen can be dipped in a cotton swab to smear a small area each time, and a large amount of quick smearing cannot be performed, and repeated operations are required.

Generally, when liquid nitrogen is used for treatment, the medical staff use cotton swabs to smear the diseased tissue comprehensively. Due to the lack of protective measures and the irreversible damage of liquid nitrogen, in order to prevent excessive damage to the surrounding good tissues, the application is very careful and slow. Only a small amount of liquid nitrogen can be dipped in a cotton swab to smear a small area each time, and a large number of quick smears cannot be performed, and repeated operations are required. The operation is cumbersome, inefficient, time-consuming and laborious, and the safety is still low
