[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following describes, in conjunction with the accompanying drawings, a lightweight 3D one-piece tension-free inguinal hernia repair patch according to an embodiment of the present invention.

[0022] like Figures 1-3 As shown, a lightweight 3D one-piece tension-free inguinal hernia repair patch according to an embodiment of the present invention includes a patch body 1 and a placement box 5 for storing the patch body 1. The patch body 1 has an axisymmetric structure and a certain curvature. Specifically, the main body of the patch body 1 is made of biocompatible and mechanically strong polypropylene material. The curvature of the patch body 1 matches the physiological structure of the inguinal region, which can better fit the patient's inguinal region and provide more uniform support. By adopting a certain appropriate curvature, the patch can completely cover the myopic foramen, which is a key area for inguinal hernia repair, helping to reduce the risk of postoperative recurrence. Furthermore, because the patch body 1 matches the anatomical structure of the inguinal region, it can more effectively cover the hernia orifice, thereby reducing the recurrence rate of hernia. The axisymmetric shape and curvature of the patch body 1 facilitates tailoring to the anatomical differences of different patients. The 3D shape better conforms to the human inguinal structure, facilitates placement, and improves the success rate of surgery and patient comfort.

[0023] The patch body 1 has several large mesh openings with uniform porosity. This large mesh structure helps to make the patch body 1 lighter and eliminates sharp edges, ensuring smooth edges and reducing damage to surrounding tissues. The specific porosity of the patch body 1 also promotes tissue growth, facilitates integration of the patch with surrounding tissues, and reduces postoperative discomfort for the patient.

[0024] like Figure 4As shown (in order to show the anchor hole 2 and the convex point 3, the large mesh structure is not shown), the anchor hole 2 is arranged around the patch body 1, and specifically, the anchor hole 2 is annularly distributed on the surface of the patch body 1, so that the user can have the fixed anchor hole 2 after cutting. Through the arranged anchor hole 2, the doctor can fix the tissue with different thicknesses according to the needs. The surface of the patch body 1 is designed with the convex point 3. Through the arranged convex point 3, the friction between the patch body 1 and the tissue can be increased, and then the displacement is prevented. The patch body 1 is further provided with a mark structure 4, and specifically, the mark structure 4 is a micro block with color coding or pattern, which is a micro block with color coding in the embodiment. Through the arranged mark structure 4, the doctor can effectively help to accurately position in the operation.

[0025] The surface of the patch body 1 and the placing box 5 is subjected to antibacterial disinfection treatment. Specifically, the surface of the patch body 1 and the placing box 5 is provided with an antibacterial coating. The placing box 5 is provided with a storage groove 6 for storing the patch body 1, and each storage groove 6 is provided with a sealing bag 7. Through the arranged placing box 5 and the sealing bag 7, the patch body 1 can be effectively stored and protected before use, and external infection is avoided. The placing box 5 is further provided with a recycling groove 8, and the recycling groove 8 is provided with a sealing cover 9. Through the arranged recycling groove 8 and the sealing cover 9, the patch body 1 cut by the doctor can be properly stored and recycled, and the utilization rate of the patch body 1 is improved.

[0026] Further comprising a degradable suture (not shown in the figure) for fixing the patch body 1. The suture is used for fixing through the anchor hole 2. Through the arranged degradable suture, the suture used in cooperation with the patch is a degradable material, which can effectively reduce the long-term foreign body reaction.
