AI Technical Summary
Traditional polypropylene hernia repair patches have poor tolerance to mechanical torsion, resulting in strong foreign body sensation after surgery, high recurrence rate and complications, especially when used at the bottom of the groin.
The patch structure consists of a mesh structure made of anti-torsion wire, a polypropylene fiber layer, and an antibacterial layer. The anti-torsion wire is made of titanium-nickel alloy wire, which has memory and elastic properties. The antibacterial layer is provided on the outside of the polypropylene fiber layer to improve the patch's mechanical torsion resistance and reduce the risk of infection.
It improves the mechanical torsion tolerance of the patch, reduces foreign body sensation, lowers the recurrence rate and the occurrence of complications, and enhances biocompatibility and antibacterial properties.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to hernia repair technical field, concretely is a kind of hernia repair patch that withstands mechanical distortion. BACKGROUND
[0002] Tension-free hernia repair surgery is repaired with patch to hernia gap, avoids the defect of postoperative pain, easy recurrence of traditional hernia repair surgery, polypropylene patch (Polypropylene Mesh.Marlex, PP) is woven from polypropylene fiber, is single-layer mesh structure, is currently preferred repair material of abdominal wall defect, in the past 50 years, polypropylene mesh has had tremendous influence on surgical field, countless patients have life prolonged because of it, many surgical difficult problems are solved because of its application, it has been confirmed to be the most popular implant in today's surgical field.
[0003] The polypropylene hernia repair patch structure on the market currently, although have the advantages that fibrous tissue proliferation is more obvious, mesh aperture is large, more conducive to fibrous tissue growth through, easy to be connective tissue infiltration, can be early and tissue inlay, but the traditional polypropylene hernia repair patch structure, the influence of its own monofilament structure leads to poor mechanical distortion resistance effect, if the operation position is close to the bottom of inguinal part, the bending of this place after operation is more frequent, easy to cause patient to feel foreign body sensation, subsequent recurrence rate and complication probability need to be reduced. UTILITY MODEL CONTENT
[0004] The utility model aims at providing a kind of hernia repair patch that withstands mechanical distortion to solve the problems raised in the above background technology.
[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of hernia repair patch that withstands mechanical distortion, including patch body, the patch body is the mesh structure woven from monofilament structure, the monofilament structure includes torsion-resistant wire, polypropylene fiber layer and antibacterial layer, the outside of the torsion-resistant wire is sleeved with polypropylene fiber layer, the outer wall of the polypropylene fiber layer is equipped with antibacterial layer.
[0006] Compared with prior art, the utility model has the beneficial effects that: the hernia repair patch that withstands mechanical distortion, compared with traditional technology, has the following advantages:
[0007] The torsion-resistant wire in the center of the monofilament structure has certain memory and elastic properties, can improve the mechanical torsion resistance of the patch body to a certain extent, and can effectively reduce the foreign body sensation in the patient's body after use, and the antibacterial effect of the antibacterial layer on the outside of the polypropylene fiber layer can reduce the recurrence rate and the probability of complications of the patient. BRIEF DESCRIPTION OF DRAWINGS
[0008] The above and other features, advantages, and aspects of the various embodiments of the present disclosure will become more apparent with reference to the following detailed description in conjunction with the accompanying drawings. Throughout the drawings, the same or similar reference numerals can refer to the same or similar elements. It should be understood that the drawings are schematic, and the original and elements are not necessarily drawn according to the scale.
[0009] Figure 1 It is a structural schematic diagram of the present application.
[0010] Figure 2 It is Figure 1 A sectional view of the monofilament structure.
[0011] In the figure: 1, patch body, 2, monofilament structure, 3, torsion-resistant wire, 4, polypropylene fiber layer, 5, antibacterial layer. DETAILED DESCRIPTION
[0012] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0013] The traditional polypropylene hernia repair patch structure is affected by the monofilament structure itself, resulting in poor mechanical torsion resistance. If the surgical site is close to the bottom of the groin, the bending of this part after surgery is more frequent, which can easily cause the patient to feel foreign body sensation, and the subsequent recurrence rate and the probability of complications need to be reduced.
[0014] Therefore, the utility model provides a kind of mechanical distortion resistant hernia repair patch, by the cooperation between patch body, monofilament structure, torsion-resistant wire, polypropylene fiber layer and antibacterial layer, the mesh patch main structure woven from monofilament structure is used during, the torsion-resistant wire in the inside center of monofilament structure, with certain memory and elastic performance, can improve the mechanical distortion resistance of patch body to a certain extent, in turn can effectively reduce the foreign body sensation in patient's body after use, with the antibacterial effect of polypropylene fiber layer outside antibacterial layer, the recurrence rate and complication probability of patient's subsequent can be reduced.
[0015] Please refer to Figures 1-2 The utility model provides a kind of technical scheme: a kind of mechanical distortion resistant hernia repair patch, including patch body 1, patch body 1 is by the mesh structure woven from monofilament structure 2, monofilament structure 2 includes torsion-resistant wire 3, polypropylene fiber layer 4 and antibacterial layer 5, the outside of torsion-resistant wire 3 is sleeved with polypropylene fiber layer 4, and the outer wall of polypropylene fiber layer 4 is equipped with antibacterial layer 5.
[0016] In the specific implementation process, it is worth pointing out particularly that torsion-resistant wire 3 is titanium nickel alloy wire, is a memory alloy, has temperature memory effect and superelasticity, can play the mechanical distortion resistance of patch body 1, can keep original design shape in human body temperature range, not easy to deform, and have good biocompatibility, reduce the stimulation and rejection reaction to human tissue, polypropylene fiber layer 4 is by screw extruder jetting primary fiber, and the center position of spinneret plate spinneret hole is evenly migrated torsion-resistant wire 3 during spinneret forming, i.e. polypropylene fiber layer 4 with the inside of torsion-resistant wire 3 is formed, antibacterial layer 5 is antibacterial peptide coating, and polypeptide copolymer in antibacterial layer 5 has good antibacterial performance, can play the infection probability of patient, in turn can make the recurrence rate and complication probability of patient's subsequent can be reduced.
[0017] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
