Embodiment 2

[0053] see Figure 10 , Figure 11 , Figure 12 , the difference between this embodiment and embodiment 2 is: the front end of the inner tube 2 has a mounting part 3 for mounting the rubber ring 1, and the mounting part 3 is provided with 2 rib groups, and the rib group consists of 3 ribs 3- 4 are evenly distributed in the circumferential direction, and each rib group is axially arranged side by side on the installation part 3, and the ribs 3-4 of the adjacent rib group are staggered from each other in the axial direction of the inner tube 2, and each rib group The teeth 4-1 and the tongues 4-2 can be accommodated between the ribs 3-4 of the group, because the teeth 4-1 at the front end of the casing 4 and the tongues 4-2 of the tongue group show a staggered structure, so the ribs The structure of the plate group is also corresponding, and it is also shown as staggered, see Figure 7 The casing 4 structure shown.

Abstract

The invention discloses a ligation device of hemorrhoids. The device is provided with a power mechanism and a rubber gasket trigger mechanism. The power mechanism controls the rubber gasket trigger mechanism which includes an inner pipe and a sleeve, wherein the inner pipe is used for loading rubber gaskets, the sleeve sleeves the inner pipe, and the sleeve moves relative to the inner pipe or the rubber gaskets translate on the inner pipe when the inner pipe moves relative to the sleeve. The rubber gaskets of the ligation device provided by the invention are installed in real time in a surgery scene, i.e. the rubber gaskets are not installed in the normal state, therefore the problems that the rubber gaskets are easily aged and fatigued can be prevented; when the ligation device is in use, the rubber gaskets can be ligated on a progressive feeding mechanism in rows, and the movement ways of the rubber gaskets are synchronous and homodromous movement after the progressive feeding mechanism obtains power, therefore the continuous launching of the rubber gaskets and the uninterrupted ligation can be ensured, and the pain of patients can be alleviated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemorrhoid ligation device specially used for hemorrhoid surgery. Background technique [0002] Hemorrhoids is a chronic disease of one or more soft veins formed by varicose venous plexuses at the bottom of the anorectum and anal mucosa. Nowadays, the medical treatment of hemorrhoids mostly adopts the method of surgical resection, which is expensive. The postoperative wound area is large, and the patient suffers from unbearable pain. In view of this reason, in clinical treatment, hemorrhoid ligation device is used. The tissue under the circle will gradually be necrotic and fall off due to lack of blood circulation, and will eventually be excreted from the body. [0003] Some hemorrhoid ligation devices on the market today mostly use a hand-held gun type. The traditional ligation device has a negative pressure system, a firing mechanism for the ligation ring, and a ...
