Description

Technical field: [0001] The invention relates to a gun, in particular to a push-pull gun for a hemorrhoid ligation device. For use with hemorrhoidal ligation. It belongs to the technical field of medical equipment. Background technique: [0002] The traditional hemorrhoid treatment gun needs to use the negative pressure system of external air, and it needs to be equipped with a negative pressure device when performing hemorrhoid treatment operation. Because the negative pressure device needs to be operated, the help of a second operator (assistant) is usually required during the operation, which limits the flexibility of the operation. And the traditional hemorrhoid treatment gun and the hemorrhoid ligation device are an integral structure, which directly contacts with the patient's lesion, has poor safety, and easily causes various infections. [0003] The hemorrhoid ligation device absorbs hemorrhoids through negative pressure. After the ligation is completed, there is ...
