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. The operation is cumberso...
