Abstract

The invention relates to a push-pull gun for matched use of the hemorrhoids ligator, comprising a gun case (2), front and back slides (14) (3), upper and lower slide gear racks (4), (6), a gear (5), a large trigger link rod (7), a large trigger (8), a ratchet (9), a small trigger (11), upper and lower link rods of small trigger (12), (13) and a thimble device (15), wherein the front and back slide lower part are inlaid inside the gun case, the upper and lower slide gear racks are displaced inside the gun case, the gear (5) is displaced between the upper and lower slide rack, the upper slide rack (4) connects with the back slide seat (3), the lower slide rack (6) hinges with the large trigger link rod (7) and the larger trigger link rod (7) hinges with the larger trigger (8), the lower part of the large trigger (8) similar to fan ratchet in shape matches with the ratchet (9), the front slide (14) hinges with the upper rod (12) of the small trigger, the upper link rod (12) hinges with the lower link rod of the small trigger (13), the lower link rod (13) hinges with small trigger (11), the thimble device is provided inside the gun case on the small trigger (11). The invention can be operated by one person conveniently without contact with focus of the patient.

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 ...

AI Technical Summary

Problems solved by technology

Because of the need to operate the negative pressure device, the help of a second operator (assistant) is usually required during the operation, which limits the flexibility of the operation

Moreover, the traditional hemorrhoid treatment gun and the hemorrhoid ligation device are an integral structure, which is in direct contact with the patient's lesion, which has poor safety and is easy to cause various infections, etc.

[0003] The hemorrhoid ligation device absorbs hemorrhoids through negative pressure. After the ligation is completed, there is a lack of negative pressure elimination facilities, so that the device and the diseased tissue cannot be separated by themselves, and it needs to be separated by force, resulting in differences in the tissues around the lesion and the rectal mucosa. Degree of injury, prone to bleeding, infection and hidden dangers of postoperative complications
