Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a parastomal hernia repair piece. Background Art

[0002] A hernia occurs when an organ or tissue in the body moves from its normal anatomical position and enters another part through a congenital or acquired weakness, defect, or hole. It is common in older and younger men. The current treatment for hernias is surgical excision followed by a patch to repair the hernia opening.

[0003] The relationship between the patch and the stoma can be categorized into two types: Keyhole and Sugarbaker. The Keyhole method often uses a specialized patch with a sleeve around the stoma, while the Sugarbaker method covers the stoma with a patch, ensuring it adheres closely to the lateral abdominal wall. The method used depends on the intra-abdominal conditions and the stoma itself.

[0004] Currently, the Keyhole method has the problem of prolapse of the transverse intestinal tube inside the abdominal cavity; the Sugarbaker method is difficult to fix the relative position of the stoma and the fistula intestinal tube, which leads to misalignment of the stoma and the fistula intestinal tube. Utility Model Content

[0005] In order to solve the above technical problems, the utility model further proposes a parastomal hernia repair piece.

[0006] The specific technical solution of the utility model is as follows: A parastomal hernia repair plate includes: a limiting plate, which is installed on the inner side of the abdominal wall and is provided with a circular hole for limiting the ostomy intestinal tube; a supporting plate is installed on the limiting plate, and the supporting plate is provided with a receiving groove for supporting the ostomy intestinal tube.

[0007] Furthermore, a through groove is provided on the limiting plate, and the through groove cooperates with the circular hole to limit the fistula intestinal tube.

[0008] Furthermore, the width of the through groove is smaller than the diameter of the circular hole.

[0009] Furthermore, the limiting piece is made of polypropylene, and the supporting piece is made of polyvinylidene fluoride.

[0010] Furthermore, the area and side lengths of the supporting piece are larger than those of the limiting piece.

[0011] Beneficial effects:

[0012] The present application is installed on the inner side of the abdominal wall through a limiting plate, and a circular hole for limiting the position of the fistula intestinal tube is provided on the limiting plate. A supporting plate is installed on the limiting plate, and a receiving groove for supporting the fistula intestinal tube is provided on the supporting plate, so that the limiting plate can fit tightly against the abdominal wall, playing the role of reinforcing the abdominal wall of the traditional keyhole procedure. The supporting plate half wraps the transverse intestinal tube and fixes it between the limiting plate and the supporting plate, playing the role of the classic sugarbaker procedure, thereby combining the advantages of the two procedures, and thus eliminating the risk of prolapse of the transverse intestinal tube in the abdominal cavity and misalignment of the stoma and the fistula intestinal tube, thereby improving the safety of use.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] Example 1: A parastomal hernia repair piece, comprising: a limiting piece 1, the limiting piece 1 is mounted on the inner side of the abdominal wall 2, the limiting piece 1 is provided with a circular hole 4 for limiting the ostomy intestinal tube 3, the limiting piece 1 is provided with a supporting piece 5, the supporting piece 5 is provided with a receiving groove 6 for supporting the ostomy intestinal tube 3, the present application is provided with a limiting piece 1 mounted on the inner side of the abdominal wall 2, the limiting piece 1 is provided with a circular hole 4 for limiting the ostomy intestinal tube 3, the limiting piece 1 is provided with a supporting piece 5, the supporting piece 5 is provided with a receiving groove 6 for supporting the ostomy intestinal tube 3 A receiving groove 6 is provided for supporting the fistula intestinal tube 3, so that the limiting plate 1 can fit closely to the abdominal wall, playing the role of reinforcing the abdominal wall of the traditional keyhole procedure. The supporting plate 5 half wraps the transverse intestinal tube and fixes it between the limiting plate 1 and the supporting plate 5, playing the role of the classic sugarbaker procedure, thereby combining the advantages of the two procedures, and thus eliminating the risks of prolapse of the transverse intestinal tube in the abdominal cavity and misalignment of the stoma and the fistula intestinal tube, thereby improving the safety of use.

[0023] Example 2: Based on Example 1, a through groove 7 is provided on the limiting plate 1, and the through groove 7 cooperates with the circular hole 4 to limit the fistula intestinal tube 3. In this application, the through groove 7 is provided on the limiting plate 1, so that when the operator needs to place the fistula intestinal tube 3 in the circular hole 4, he can use a tool to flatten the fistula intestinal tube 3 and place the fistula intestinal tube 3 in the circular hole 4 through the through groove 7, thereby avoiding damage caused by friction when the fistula intestinal tube 3 passes directly through the circular hole 4, thereby improving the safety of use.

[0024] Example 3: Based on Example 2, the width of the through groove 7 is smaller than the diameter of the circular hole 4. In this application, the width of the through groove 7 is smaller than the diameter of the circular hole 4, so that the fistula intestinal tube 3 can be clamped and limited by the circular hole 4 after passing through the through groove 7 and releasing the clamping, thereby improving the convenience of use.

[0025] Example 4: Based on Example 1, the limiting plate 1 is made of polypropylene and the supporting plate 5 is made of polyvinylidene fluoride. In this application, the limiting plate 1 is made of polypropylene and the supporting plate 5 is made of polyvinylidene fluoride, so that the limiting plate 1 made of PP (polypropylene) is easy to soften and plastically fit the abdominal wall 2, and the material has good stability and is not easily deformed or chemically reacted due to the temperature or other factors in the abdominal cavity; the supporting plate 5 made of PVDF (polyvinylidene fluoride) has high tissue isolation performance, which can effectively avoid adhesion of the supporting plate 5 and other tissues in the abdominal cavity, thereby improving the stability of use.

[0026] Example 5: Based on Example 4, the area and each side length of the supporting piece 5 are larger than those of the limiting piece 1. In this application, the area and each side length of the supporting piece 5 are larger than those of the limiting piece 1, so that the PP (polypropylene) wire of the PP (polypropylene) material limiting piece 1 forms adhesion with other tissues in the abdominal cavity, thereby improving the stability of use.

[0027] Working process:

[0028] When it is necessary to fix the fistula intestinal tube 3, first clamp the fistula intestinal tube 3 so that it passes through the through groove 7 and enters the circular hole 4, loosen the clamping so that the circular hole 4 clamps the fistula intestinal tube 3, and then place the end of the fistula intestinal tube 3 at the abdominal stoma, and at the same time make the limiting plate 1 fit the abdominal wall 2 and fix it, place the transverse intestinal tube of the fistula intestinal tube 3 in the receiving groove 6, and finally fix the supporting plate 5 on the limiting plate 1.
