Description

Technical Field

[0001] This utility model relates to the field of hernia repair patch technology, specifically to a composite hernia repair patch that is easy to fix. Background Technology

[0002] When treating hernias, hernia repair patches are needed. Hernia repair patches are mainly used for hernia repair. Composite hernia repair patches refer to hernia repair materials that combine two or more different materials to form a specific function. This design aims to combine the advantages of different materials, such as mechanical strength, tissue compatibility, and anti-adhesion properties.

[0003] Existing composite hernia repair patches are used by cutting the patch to a suitable size and placing it at the hernia defect site, ensuring that the patch fully covers the hernia defect area and is accurately positioned. The patch is usually placed in the preperitoneal space. After placement, it is pre-fixed with medical adhesive. Finally, it is fixed to the hernia repair patch and the incision with sutures or hernia staples. However, when the adhesive is sprayed between the patch and the incision, it may overflow. Most of the adhesive may flow out of the patch area, resulting in poor pre-fixation of the patch, which will affect the subsequent suturing or hernia staple work. Utility Model Content

[0004] In view of the problems existing in the current composite hernia repair patch that is easy to fix, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a composite hernia repair patch that is easy to fix, which solves the problem that when pre-fixing existing composite hernia repair patches, most of the glue may flow out of the patch area, resulting in poor pre-fixation effect of the patch and thus affecting subsequent suturing or hernia nailing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a composite hernia repair patch that is easy to fix.

[0027] This utility model provides, for example Figure 1-4 The composite hernia repair patch shown includes a patch body 1, a support layer 2, a plurality of lightweight large-mesh mesh 3 fixedly connected to the surface of the support layer 2 through multiple openings, the support layer 2 includes a skeleton layer 4, a biological layer 5 fixedly connected to one side surface of the skeleton layer 4, an anti-adhesion layer 6 fixedly connected to the top of the biological layer 5, and an accelerating coating 7 fixedly connected to the other side surface of the skeleton layer 4.

[0028] A retaining and absorbent strip 8 is fixedly connected to the surface of the coating 7. The retaining and absorbent strip 8 has multiple pre-drilled through holes 9. The surface of the patch 1 is covered with an antibacterial coating 10. A protective mechanism is provided on the outside of the patch 1. The lightweight large-mesh mesh 3 is a polypropylene large-mesh mesh, the skeleton layer 4 is a polypropylene skeleton layer, the retaining and absorbent strip 8 is an absorbent strip made of polyethylene glycol hydrogel, and the antibacterial coating 10 is an antibacterial coating made of chitosan. The patch 1, composed of the lightweight large-mesh mesh 3 and the support layer 2, facilitates the covering and reinforcement of the defect, restores the integrity of the abdominal wall, and prevents the recurrence of hernia. The retaining and absorbent strip 8 absorbs and locks in the sprayed medical adhesive, allowing the medical adhesive to better adhere between the patch 1 and the abdominal cavity, facilitating the fixation of the patch 1. Multiple pre-drilled through holes 9 facilitate suturing the patch 1 to the incision using suture needles or hernia staples. An antibacterial coating 10, made of chitosan, prevents inflammation caused by bacteria. A lightweight, large-mesh polypropylene mesh 3 reduces inflammation and scar formation while promoting soft tissue regeneration. An anti-adhesion layer 6 prevents adhesion to internal organs during insertion. A promoting coating 7 promotes cell and tissue growth. A biological layer 5 reduces postoperative inflammation and adhesion formation, rapidly inducing tissue regeneration and vascularization. This solves the problem of existing composite hernia repair patches where glue may flow out of the patch area during pre-fixation, resulting in poor pre-fixation and affecting subsequent suturing or hernia staple work.

[0029] To ensure the patch body 1 is sealed and protected before use, such as Figure 1 As shown, the protective mechanism includes a protective bottom base paper 11, a protective top cover paper 12, and an adhesive layer 13. The bottom base paper 11 is slidably connected to one side of the patch body 1, and the protective top cover paper 12 is fixedly connected to the side wall of the bottom base paper 11. The inner side walls of both the protective bottom base paper 11 and the protective top cover paper 12 are fixedly connected to the adhesive layer 13, and the adhesive layers 13 at both ends are bonded to each other. By using the protective mechanism composed of the bottom base paper 11, the protective top cover paper 12, and the adhesive layer 13, the patch body 1 is sealed and protected before use.

[0030] To reduce postoperative inflammation and adhesion formation, such as Figure 3 and 4 As shown, biolayer 5 is the biomembrane layer. By utilizing biolayer 5, which is set as a biomembrane, postoperative inflammatory response and adhesion formation can be reduced, and tissue regeneration and vascularization can be rapidly induced.

[0031] To avoid adhesion to internal organs and affecting its use, such as Figure 3 and 4As shown, the anti-adhesion layer 6 is a collagen layer anti-adhesion layer. By using the anti-adhesion layer 6, which is set as a collagen layer, adhesion to internal organs can be avoided, thus preventing it from affecting use.

[0032] To promote the rapid ingrowth of cells, blood vessels, and other tissues into the patch, such as... Figure 3 and 4 As shown, the promoting coating 7 is a silk fibroin promoting coating. Utilizing this silk fibroin promoting coating 7, cells, blood vessels, and other tissues are rapidly ingrained into the patch, accelerating tissue repair and regeneration. As tissue repair progresses, the silk fibroin patch slowly degrades, ultimately achieving repair through the body's regenerated tissue.

[0033] To facilitate tearing open the protective bottom base paper 11 and the protective top cover paper 12, such as Figure 1 As shown, the side walls of the protective bottom base paper 11 and the protective top cover paper 12 are both fixedly connected with easy-tear edges 14. By using the easy-tear edges 14, it is easy to tear open the protective bottom base paper 11 and the protective top cover paper 12 to remove the patch body 1.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
