Automatic hemorrhoid ligation device with sunken points

Abstract

The invention relates to an automatic hemorrhoid ligation device with sunken points. The automatic hemorrhoid ligation device comprises a rubber ring body, a ring expanding joint, an upper ring joint, a suction tube, a push pipe, a reset spring, a transmitting pipe, a trigger and a handle, wherein the rubber ring body is installed on the peripheral surface of a near-end tube orifice of the suction tube by means of the ring expanding joint and the upper ring joint; one end of the suction tube is connected with the handle, and the other end of the suction tube is connected with the ring expanding joint; the ring expanding joint comprises a ring expanding part and a connecting part; three sliding strips are fixedly arranged on the peripheral surface of the ring expanding part; a ring-shaped groove is formed in the junction of the connecting part and the ring expanding part; the upper ring joint is provided with a cavity matched with the ring expanding joint; the inner wall of the cavity is provided with three sliding rails; the rubber ring body is provided with the sunken points. The automatic hemorrhoid ligation device with the sunken points has the advantages that rubber rings can be conveniently installed on the device, and ligation is realized by means of occlusion, so that the automatic hemorrhoid ligation device has wet-skid resistance, can be firmly fixed and does not easily fall off.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic hemorrhoid ligation device with sunken points. 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] In actual operation, the rubber ring ligation device used has the following defects and deficiencies: [0004] 1. In the prior art, the rubber ring is the core component. However, the inner surface of the ...

Problems solved by technology

However, the apron needs to be assembled on the suction pipe to use it. Because the aperture of the apron is very small, it is generally necessary to use external instruments to install the apron tube on the suction tube, and there is no special method in the prior art. The ring expander is easily deformed when it is expanded and installed with other instruments

As a result, the apron has poor wet-slip resistance during ligation, is not firmly fixed, and is easy to fall off

[0006] 3. The development of the ligation device in the prior art has always focused on the innovation of the device itself, but the research and development of the ligation rubber ring is rarely mentioned. The natural rubber in the prior art is made of a rubber ring. Due to the natural rubber biological Compatible type is average, easy to cause rejection, leading to infection and inflammation, poor anti-wet skid performance, weak bandage, easy to fall off the rubber ring; protein and cells adhere to the surface of the material, easy to breed bacteria, and at the same time, the pain of the patient is aggravated

However, there is no corresponding disclosure about a technical solution that is convenient to install the apron, can be ligated by occlusion, is anti-wet, and is firmly fixed and not easy to fall off.
