Embodiment 1

[0033] The preperitoneal inguinal hernia patch of the present embodiment, such as figure 1 As shown, for placement between the peritoneum and transversalis fascia and covering the entire musculopubic foramen.

[0034] The patch is elliptical and folded into upper half 2 and lower half 3 along its long axis 1 of the ellipse. When in use, the long axis 1 of the ellipse of the patch is placed along the iliopubic tract with one end pointing to the pelvic cavity. The upper half of the patch The angle between the part 2 and the lower half 3 is 50-70°.

[0035] The lower half 2 of the patch is folded with an outwardly turned flanging 4, and the flanging 4 is an arc surface, and its arc is connected to an end point of the major axis 1 of the ellipse and a point on the edge of the ellipse of the lower half 2 of the patch. arc segment.

[0036] The patch of this embodiment is a heavy patch made of ordinary polypropylene of 80-110g / m². The major axis 1 of the ellipse is 12-14 cm, and ...

Embodiment 2

[0038] The preperitoneal inguinal hernia patch of the present embodiment is an improvement on the basis of the first embodiment, and the difference with the first embodiment is: as figure 2 As shown, the lower half 2 of the patch of the present embodiment does not have an upwardly folded-outward flanging 4, but is formed with a cut edge 5 on the lower half 2 of the patch, and the cut edge 5 is connected to the major axis of the ellipse. 1 One end point and the lower half of the patch 2 A straight line segment at a point on the edge of the ellipse. The patch of this embodiment is a heavy patch made of ordinary polypropylene of 80-110g / m².

Embodiment 3

[0040] The preperitoneal inguinal hernia patch of the present embodiment is an improvement on the basis of the first embodiment, and the difference with the first embodiment is: as image 3 As shown, the upper half 2 and the lower half 3 of the patch are heavy-duty patches made of ordinary polypropylene of 80-110g / m², and the 4 folds are made of macroporous polypropylene less than 30g / m² Made of lightweight patches.

[0041] The present invention covers the entire musculopubic foramen by implanting a patch between the peritoneum and the transversalis fascia, which has the characteristics of short operation time, less anatomical separation, and less implanted materials, especially without the need to place a patch under the aponeurosis of the external oblique muscle. (that is, in the inguinal canal) to implant the mesh material, which can effectively reduce the complications after hernia repair, especially the incidence of chronic pain. It is safer to enter directly under dire...

Abstract

The invention relates to a peritoneal front inguinal hernia repairing mesh and belongs to the technical field of medical prostheses. The mesh is put between the peritoneum and the fascia trans versalis and covers the whole myopectineal orifice, and the mesh is oval and is folded in half along the long axis of the oval to obtain an upper half part and the lower half part. When the mesh is used, the long axis of the oval of the mesh is placed along the iliopubic tract, one end points to the pelvic cavity, an included angle formed by the upper half part and the lower half part of the mesh is 50-70 degrees, a camber surface shaped folding edge turned outwards is folded on the lower half part of the mesh, and the arc edge of the folding edge is an arc section connected with one end point of the long axis of the oval and one point on the oval edge of the lower half part of the mesh or a linear section cut edge connected with one end point of the long axis of the oval and one point on the oval edge of the lower half part of the mesh is made on the lower half part of the mesh, the upper half part and the lower half part of the mesh are heavy weight type meshes made from 80-110 g / <2> of common polypropylene, and the folding edge is a light weight type mesh made from 30 g / <2> of microporous polypropylene. The mesh has the advantages of being safe, comfortable and very simple in structure.

Description

technical field [0001] The invention relates to a hernia repair sheet, which belongs to the technical field of prosthesis in medicine. Background technique [0002] A hernia is a part of a human tissue or organ that leaves its original location and enters another location through a gap, defect or weakness in the body. The traditional treatment method is to suture and repair the tissue at the defect site. This method has a high recurrence rate, severe pain, and slow recovery. [0003] In recent years, the use of artificial materials for tension-free hernia repair has been widely praised throughout the world. This method can reduce postoperative pain, and has the advantages of fast recovery and low recurrence rate. The traditional hernia repair patch has low hardness and cannot bear the pressure from the abdominal cavity after being implanted in the human body. The mesh plug often moves outside the body or into the abdominal cavity, resulting in hernia recurrence or other ser...
