Curved suction internal hemorrhoid cerclage

Abstract

The utility model relates to a curved-suction internal hemorrhoid cerclage device. It includes a curved tip inner tube, a curved sleeve to release the silicone ring, a barrel push sleeve and a negative pressure syringe. The arc-shaped suction head can easily absorb internal hemorrhoid tissue and rectal mucosa supplying blood vessels on the rectal wall with an L-shaped structure above the dentate line of the anal canal, and then perform cerclage. It is easy to operate with one hand and reduces the operation time. The negative pressure syringe has dual functions of generating negative pressure and serving as a handle of the cerclage, which simplifies the structure of the cerclage. The push sleeve track, track guide cylinder and wedge can ensure the smooth movement of the curved sleeve releasing the silicone ring along the inner tube of the curved tip, and it is not easy to fall off. The semi-circular wheel turns the curved surface between the cylindrical push sleeve and the arc-shaped sleeve that releases the silicone ring, thereby generating rolling contact and directly transmitting the power to the silicone ring to achieve light and smooth release of the silicone ring for cerclage Effect. The invention is reasonable in design, easy to use, and low in cost, so it is suitable for one-time use.

Description

technical field [0001] The invention relates to a medical device, which is used for treating internal hemorrhoids of daily outpatients or inpatients. Background technique [0002] Internal hemorrhoids are a common type of hemorrhoids. From the perspective of human anatomy, internal hemorrhoids are located in the rectal mucosa above the anal dentate line. Internal hemorrhoids often appear in plexus, which can be single or two to three plexus. Each internal hemorrhoid usually has a specific supply blood vessel running under the rectal mucosa, forming an internal hemorrhoid structure at the anal teeth from top to bottom. Studies have shown that the method of effectively blocking the supply blood vessels of internal hemorrhoids to achieve the treatment of internal hemorrhoids is more effective than directly treating the internal hemorrhoids themselves. Because the cerclage site is above the dentate line, there is no pain sensory nerve, which can block the main blood supply ve...

Problems solved by technology

However, due to the pressure of the rectal wall, the elastic tube is difficult to bend after entering the rectum, and only the part outside the body can be bent, which fails to achieve the purpose of making the opening better suck hemorrhoid tissue
