Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a repair device used for tension-free repair of inguinal hernia. Background Art

[0002] Hernia is a common and frequently occurring disease in general surgery, among which inguinal hernia is the most common type of extra-abdominal hernia. Hernia may cause local pain, which may affect daily activities and cause physical weakness. Therefore, surgical intervention is required for hernia. Traditional surgical treatments are mostly repair treatments with tension, which can cause severe discomfort to patients. Therefore, when repairing hernias, medical polymer materials are often used to repair hernias without tension. For example, the application number is CN201721186020.8, which is a polypropylene three-dimensional villi mesh plug used for tension-free hernia ring filling repair, and relates to the field of tension-free hernia repair. The structure is woven into an integral structure by polypropylene monofilaments, including a multi-layer skeleton, wherein the skeleton is tightly woven by polypropylene monofilaments, and each layer of the skeleton is surrounded by a sparsely woven pile loop made by polypropylene monofilaments, forming a three-dimensional structure with multiple villi tentacles and a low capacity. The three-dimensional structure can enable the mesh plug system to perfectly fill and adapt to various hernia ring structures. Successful adaptation and filling can minimize the recurrence of the disease. The skeleton includes four layers, and each layer of the skeleton is in a circular shape. The diameter of each layer of the skeleton arranged from bottom to top decreases successively. The skeleton is woven in parallel, and the pile loop is woven in a surrounding manner. The structure with multiple villi tentacles can increase and strengthen the contact area with the surrounding tissues, so that the mesh plug system is stable and does not shift after implantation, which is conducive to the rapid growth of tissues and accelerated wound healing. It has high biocompatibility, patient adaptability, safety and reliability. The sparse weaving of the pile loops makes the capacity of the mesh plug system low, which can reduce the body's foreign body rejection reaction.

[0003] The hernia tension-free repair device in the above-mentioned document may cause mesh displacement in the body due to the failure to fix the mesh. At the same time, the outer mesh may curl at the edges if it is not fixed during use, thus affecting subsequent treatment.

[0004] For example, the two-in-one patch for tension-free herniorrhaphy with application number CN200610070710.7 integrates a variety of patch design concepts, and the size of the patch is cut according to the anatomic anterior and posterior spaces of the transverse abdominal fascia; the patch with a large area is spread out in the anterior peritoneal space around the spermatic cord, covering the internal ring opening, Hersh triangle, the internal opening of the femoral canal and the posterior belly of the ipsilateral rectus abdominis, without missing the hernial orifice; at the same time, the overlapping area of ​​the patch is used as the spermatic cord outlet to more accurately control the expansion of the cord hole (normal 0.5-0.8cm, the expansion value is ±0.2cm) to prevent hernia prolapse; the patch with a small area is fixed to the Hersh triangle and the transverse abdominal fascia. In this way, the three weak links of inguinal hernia (hernial ring, transverse abdominal fascia defect or pubic muscle foramen, posterior wall of the inguinal canal) are repaired and strengthened respectively, and the occurrence of direct hernia, oblique hernia or even femoral hernia is effectively prevented. Because all flat patches are used, the recurrence rate and the hospitalization expenses of patients are greatly reduced. At the same time, the small patch is covered by the spermatic cord and the sutured levator testis muscle, and the thickness away from the body surface is increased. Moreover, the thickness of the patch can be adjusted according to the condition of the abdominal wall. A thinner patch is selected for patients with less subcutaneous fat and a flat abdominal wall; a thicker patch is selected for patients with more subcutaneous fat and a bulging abdominal wall. It lays the anatomical foundation for alleviating postoperative discomfort, combines the three basic surgical features of Stoppa, Lichtenstien, and Plug, and can control the expansion degree of the spermatic cord hole of the patch. The circumferential fixation of a small patch prevents the patch from rotating and shifting, keeps the levator testis muscle and spermatic cord in situ, increases the area of ​​the patch in the preperitoneal space, does not cover the nerves, replaces and strengthens the defects of the transverse abdominal fascia that constitutes the inner ring, and leaves no gaps.

[0005] The tension-free hernia repair device in the above-mentioned document has a patch placed in the preperitoneal space that is mostly a single-layer disc with a soft texture. When repairing the deeper peritoneum, the gap between the patch and the peritoneum is small, and it is difficult to unfold the disc, which inevitably causes curling and folding of the patch, thus seriously affecting the treatment effect.

[0006] Therefore, we propose a repair device for tension-free repair of inguinal hernia to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a repair device for inguinal hernia tension-free repair to solve the problem proposed in the above-mentioned background technology that the hernia ring filling tension-free repair currently on the market may cause mesh displacement in the body due to the mesh not being fixed, and the mesh may cause edge curling due to the mesh not being fixed during use.

[0013] Preferably, the folding groove is triangular in design, the lateral push rod is obliquely arranged on the upper and lower sides of the active push rod, and the position of the lateral push rod corresponds to that of the support plate.

[0014] Preferably, the support plate unfolds the flat lower sheet through the folding groove, the active push rod and the lateral push rod are an integrated structure, and the support plate is unfolded by the lateral push rod.

[0015] Preferably, the flat lower sheet is divided into a smooth mesh layer and a barbed mesh layer, and the smooth mesh layer is located on the upper side of the barbed mesh layer, and a mesh body is arranged on the smooth mesh layer; The lower end of the barb grid layer is fixedly connected with a barb body.

[0016] Preferably, the grid body is woven from polypropylene monofilaments, and pile loops are provided at the connection points of the grid body.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The double-layer mesh setting of the flat lower piece and the mesh plug upper piece can better locate and repair the patient's wound, reducing the possibility that the patch cannot completely cover the hernia orifice. The double-layer patch design can be placed in the preperitoneal space, improving the adaptability of the patch. The flat lower piece can repair the posterior wall of the inguinal canal, reducing the risk of hernia recurrence, and the mesh plug upper piece can fill the vacant part of the hernia. (2) When the medical staff inserts the mesh plug upper piece into the patient's diseased part, they can pull the connecting rope outward.
