Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a hernia patch for treating inguinal hernia. Background Art

[0002] Hernia refers to a tissue or organ in the body that leaves its normal anatomical position and is formed through congenital or acquired weaknesses, defects or gaps. It is a common and frequently occurring disease in general surgery, among which extra-abdominal hernia is the most common, especially inguinal hernia, which accounts for about 90% to 95% of extra-abdominal hernias.

[0003] Since 1984, American surgeon Lichtenstein has routinely used polypropylene mesh for inguinal hernia repair. In 1989, he proposed the concept of "tension-free" hernia repair, which was named Lichtenstein operation. He also pointed out that: (1) Inguinal hernia surgery cannot be regarded as a simple operation and should be performed by experienced specialists. (2) Inguinal hernia surgery can be performed under local anesthesia. (3) Inguinal hernia surgery can be performed as an "outpatient" operation. These advanced concepts still have important practical significance. At present, Lichtenstein operation and laparoscopic surgery represented by transabdominal preperitoneal hernia repair (TAPP) and total extraperitoneal hernia repair (TEP) are considered to be the "gold standard" for the treatment of inguinal hernia. The choice of surgical procedure is mainly based on the principle of individualization. In addition, comprehensive factors such as the doctor's own experience, the patient's wishes, and the conditions of the medical institution should also be considered.

[0004] The main goal of the Lichtenstein procedure is to use a patch to repair the posterior wall of the inguinal canal. Due to the physiological structure - the spermatic cord or the round ligament of the uterus, the patch needs to be cut from the outside to accommodate the spermatic cord during the repair process. At the same time, a key point of this step is not only to flatten the two tail ends of the cut patch around the spermatic cord, but also to dovetail fold the two tail ends of the patch (the flat patch is cut like a dovetail, and folding means that the upper and lower halves overlap), so that the upper half of the patch covers the part of the spermatic cord near the inner ring downward; its purpose is to create an artificial inner ring constructed by the patch to prevent the recurrence of indirect hernia after surgery. Existing conventional flat patches (completely flat patches) can be dovetail folded, but after the upper half of the flat patch covers the round spermatic cord and folds down to the lower half of the patch, the flat patch will change from a plane to a three-dimensional shape in the folded part, resulting in the patch being unable to fit, causing the patch at the inner edge of the fold to be uneven, which may affect the integrity of the repair or cause local thickening of the scar to cause discomfort and pain.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a hernia patch for treating inguinal hernia, which solves the problems of poor repair integrity and strong postoperative discomfort in the prior art.

[0028] Specifically, Figures 1 to 8 As shown, the hernia patch includes a patch body 1 and an auxiliary patch 2, the patch body 1 is provided with a through hole 11 and a gap 12 along the through hole 11 to the edge of the patch body 1, the auxiliary patch 2 is connected to the patch body 1, and the auxiliary patch 2 is configured such that after the patch body 1 is attached to the inguinal surgical position, the auxiliary patch 2 covers the target area of ​​the upper plane of the patch body 1, and the through hole 11 is located in the target area.

[0029] Specifically, the through hole 11 is used to accommodate the spermatic cord, and the gap 12 is used to assist the spermatic cord to pass through. Further, in this embodiment, by providing the auxiliary patch 2, the dovetail structure can achieve better wrapping of the spermatic cord without wrinkles, so that the patch body 1 can be placed snugly, improving the repair integrity, and after the patch body 1 is placed snugly, the friction and tension of the surrounding tissues are balanced, alleviating postoperative discomfort.

[0030] In an operative solution, the patch body 1 comprises a first fitting portion 13 and a second fitting portion 14 connected to each other, wherein the first fitting portion 13 is constructed as an arc structure, and the second fitting portion 14 is constructed as a rectangular structure. Exemplarily, the first fitting portion 13 may be an arc structure, and the first fitting portion 13 is constructed as a semicircle, comprising an arc segment and a first straight line segment, a second straight line segment and a third straight line segment connected in sequence, wherein the first straight line segment and the third straight line segment are symmetrically arranged, one end of the arc segment is connected to the first straight line segment, the other end of the arc segment is connected to the third straight line segment, and the two ends of the second straight line segment are respectively connected to the first straight line segment and the third straight line segment. The third straight line segment is a common line segment of the first fitting portion 13 and the second fitting portion 14. Further, in an example, the second fitting portion 14 comprises a first edge 141, a second edge 142, a third edge and a fourth edge connected in sequence, wherein the third straight line segment is collinear with the third edge.

[0031] In an implementable solution, the through hole 11 is provided in the second fitting portion 14, and the slit 12 extends from the through hole 11 to the bottom of the through hole 11 to the first edge 141 of the second fitting portion 14.
