Anti-adhesion hernia repair patch and weaving method thereof

Abstract

The invention relates to an anti-adhesion hernia repair patch and a weaving method thereof, belonging to the technical field of biological medicines, and particularly relating to the technical field of medical hernia repair patch material weaving. The anti-adhesion hernia repair patch is provided with a mesh base fabric woven by using polyvinylidene fluoride or teflon monofilaments, polypropylene monofilaments and polyvinylidene fluoride or teflon monofilaments are lapped to be a circle on the back face of the mesh base fabric, and the circle is connected with the mesh base fabric so as to form a polypropylene weaving layer, thereby forming a double-layer weaving structure made of different materials. The weaving method comprises the following steps that: an operation of weaving is performed by using two guide bars on a standard warp knitting machine, wherein the rear guide bar L2 completely passes through polyvinylidene fluoride or teflon monofilaments, carries out left-and-right traverse lap along a needle bed, and carries out fancy knitting on a tricot stitch structure so as to form a mesh base fabric; and the front guide bar L1 completely passes through polypropylene monofilaments and just carries out an intermittent overlap motion on a longitudinal single knitting needle, the monofilaments and the rear guide bar L2 are horizontally lapped to be a circle, the circle is connected with the mesh base fabric, and the rest of rows are arranged on the back face of the mesh base fabric in a float line mode and connected with the mesh base fabric so as to form a polypropylene weaving layer.

Description

technical field [0001] The invention relates to an anti-adhesion hernia repair patch and a weaving method thereof, belonging to biomedicine, in particular to the technical field of medical hernia repair patch material weaving. Background technique [0002] It is very difficult to repair large tissue defects in the chest wall, abdominal wall, etc., not only need to use suitable repair materials, but also have a suitable repair structure. At present, the widely used artificial patch materials mainly include polypropylene mesh (Marlex, Prolene mesh), polytetrafluoroethylene patch (PTFE, Gore-Tex patch), polyester patch, etc. However, the implantation of traditional artificial materials in the body will increase the chance of wound infection, and postoperative infection is the biggest complication; after long-term implantation, deformation and wrinkles can lead to granulation hyperplasia, pain and discomfort, seroma, infection, and fistula formation Complications such as vas...

AI Technical Summary

Problems solved by technology

However, the implantation of traditional artificial materials in the body will increase the chance of wound infection, and postoperative infection is the biggest complication; after long-term implantation, deformation and wrinkles can lead to granulation hyperplasia, pain and discomfort, seroma, infection, and fistula formation Complications such as vascular destruction, so it is necessary to find more ideal organ tissue repair materials

[0003] At present, there is an anti-adhesion hernia repair sheet, which is composed of polypropylene mesh and composite polytetrafluoroethylene diaphragm. After implanting in the human abdominal cavity, fibroblasts and macrophages are not easy to enter the micropores, so the repair is firm. In addition, the polytetrafluoroethylene diaphragm is not easy to combine with the polypropylene mesh, and it is easy to separate and affect the surgical effect
