Description

Prevent ureteral intestinal anastomotic stoma stenosis support Technical Field The utility model belongs to the technical field related to urinary medical treatment, and particularly relates to a bracket for preventing ureteral intestinal anastomosis stenosis. Background In the medical field of the urinary system, ureteral enteroanastomosis is an important surgical procedure. However, post-operative ureteral enterostomy stenosis has been a serious problem for doctors and patients. The traditional treatment method has a plurality of limitations in preventing ureteral intestinal anastomosis stenosis. The common medical stent is often not suitable for the special structure and physiological environment of the ureteral intestinal anastomosis, the anastomosis is possibly damaged in the process of putting in and taking out, the operation is not smooth enough, and the pain of a patient and the difficulty of operation are increased. On the other hand, the conventional stent is unsatisfactory in the effect of preventing stenosis, and it is difficult to effectively maintain the patency of the stoma, resulting in the problem of stenosis being liable to occur again. In addition, in terms of material selection, the conventional stent may induce immune and inflammatory reactions in the human body, cannot be stably retained in the body for a long time, and requires frequent replacement of the stent, which not only brings physical burden to the patient, but also increases medical cost and the number of operations. In view of the above, there is a great need for an innovative stent for preventing ureteral intestinal anastomosis stenosis, so as to solve the problems of the conventional method in the field. Disclosure of utility model The utility model aims to provide a ureteral intestinal anastomosis stenotic stent, which aims to solve the problems that the traditional ureteral intestinal anastomosis stenotic stent is easy to cause infection and shift. The technical scheme is that the ureteral intestinal anastomosis stenosis prevention support comprises a stenosis prevention support, wherein the front end of the stenosis prevention support is fixedly connected with a guiding-out ring, and the rear end of the stenosis prevention support is fixedly connected with a guiding-in ring. Preferably, the anti-stenosis bracket is arranged in a truncated cone shape and is arranged in a grid shape, and the cross sections of the export ring and the import ring are all circular. Preferably, the radius of the leading-out ring is larger than that of the leading-in ring, and the anti-stenosis bracket, the leading-out ring and the leading-in ring are all made of titanium alloy. Preferably, the anti-stenosis bracket is externally wrapped with a covering film, and the covering film is positioned between the export ring and the import ring. Preferably, the outer parts of the leading-out ring and the leading-in ring are sleeved with a plurality of fixing belts, and the covering film and the plurality of fixing belts are made of absorbable materials. Preferably, the anti-stenosis bracket is fixed at the junction of the bladder and the ureter by a plurality of fixing belts and absorbable suture lines, the export ring is fixed at the bladder end, and the import ring is fixed at the ureter end. Compared with the prior art, the utility model provides the bracket for preventing ureteral intestinal anastomosis stenosis, which has the following beneficial effects: 1. The structure design is reasonable, the conical frustum-shaped grid-shaped anti-stenosis bracket is matched with the leading-out ring with a larger radius at the front end and the leading-in ring with a smaller radius at the rear end, so that the bracket can be put into and taken out of the ureteral intestinal anastomosis port more smoothly, the injury to the inside of the anastomosis port is reduced, the operation convenience is greatly improved, and the trumpet-shaped design can better play the role of preventing the anastomosis port from being narrow, and the effect is remarkable. 2. The material has obvious advantages that the anti-stenosis bracket, the export ring and the import ring are manufactured by adopting titanium alloy, so that the immune reaction and the inflammatory reaction of a human body are reduced, the anti-stenosis bracket can stay in the body for a long time without causing infection, and the pain and the risk of a patient caused by the discomfort of the bracket material are reduced. 3. The protective function is strong, the covered membrane wrapped outside can effectively prevent the tissue inside the anastomotic stoma from being extruded into the meshes of the bracket, so that the damage to the tissue is avoided, the combination of the bracket and the tissue is prevented, the bracket is difficult to take out, convenience is provided for the subsequent treatment of a patient, the fixing band adopts absorbable materials, the bracket is fixed at the joint of the bladder
