Abstract

The invention relates to an automatic hemorrhoids ligation device with raised strips. The automatic hemorrhoids ligation device comprises a rubber ring body, a rubber ring tube, a rubber ring tube connector, a suction tube connector, a suction tube, an advancing tube, a reset spring, a transmission tube, a trigger and a handle, wherein the advancing tube, the reset spring and the transmission tube are arranged on the outer peripheral face of the suction tube; one end of the reset spring is connected with the advancing tube, and the other end of the reset spring is connected with the transmission tube; the near end of the suction tube is connected with the handle; the rubber ring tube connector and the rubber ring tube are integrally formed, the rubber ring tube connector is a standard part, and the rubber ring tube connector can be correspondingly connected with rubber ring tubes of different inner diameters; the rubber ring body is provided with the raised strips, and the raised strips are annularly distributed on the inner side of the rubber ring body in an equal-distance manner to form an occlusion part. The automatic hemorrhoids ligation device has the advantages that the device can be matched with hemorrhoids of different sizes, ligation can be achieved through occlusion, and the device is resistant to wetness and slipperiness, firm in fixation and less prone to falling off.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic hemorrhoid ligator with protruding strips. Background technique [0002] Hemorrhoids are a chronic disease of one or more soft venous clusters formed by the varicose venous plexus at the bottom of the anorectum and anal mucosa. The current medical treatment of hemorrhoids uses surgical resection, which is expensive. The postoperative trauma area is large and the patient’s pain is unbearable. For this reason, in clinical treatment, hemorrhoid ligator is used. The hemorrhoid ligator is used to suck the hemorrhoid tissue through negative pressure, and then use a rubber ring to ligate. The tissue under the circle will gradually become necrotic and fall off due to the lack of blood circulation, and will eventually be discharged from the body. [0003] In actual operation, the rubber band ligator used has the following defects and deficiencies: [0004] 1. In the prior ar...
