[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, an embodiment of the present utility model provides a technical solution: an automatically fixed inguinal hernia repair patch, which includes an outer repair patch 1 and an inner repair patch 3. The inner repair patch 3 is placed inside the outer repair patch 1, and five annularly distributed fixing pieces 2 are integrally formed on the outer wall of the inner repair patch 3. The fixing pieces 2 are integrally in an arc structure, and fixing disks 5 are formed at the surface ends. The back of the fixing disks 5 is connected to the outer repair patch 1. Three groups of first fixing nails 4 arranged in an arc are formed on the surface of the fixing pieces 2. The arc arrangement has better tensile performance. The fixing disks 5 are in a circular structure, and several second fixing nails 7 distributed in a ring are formed on the surface. The double fixation of the first fixing nails 4 and the second fixing nails 7 improves the fixing effect and stability.

[0021] Further improved, several convex portions 6 are formed at the surface edge of the inner repair patch 3. The convex portions 6 are in an inverted frustum shape. The convex portions 6 play a certain supporting role and reduce the adhesion between the inner repair patch 3 and the internal organs.

[0022] Further improved, the outer repair patch 1, the inner repair patch 3 and the fixing pieces 2 are all composed of an antibacterial layer 9, a blocking layer 10 and a structural layer 11. And the blocking layer 10 is located between the structural layer 11 and the antibacterial layer 9. The antibacterial layer 9 is made of a nano-silver composite medical antibacterial material, which increases the antibacterial performance of the hernia repair patch and reduces the probability of wound infection of the patient. The blocking layer 10 is made of a hydrophobic breathable membrane to make the hernia repair patch breathable while preventing liquid from seeping out on one side of the hernia repair patch. The structural layer 11 is made of expanded polytetrafluoroethylene material; the polypropylene material mesh tissue grows well, and it grows firmly on the abdominal wall after implantation. And the expanded polytetrafluoroethylene material can be placed in the abdominal cavity to contact the internal organs, and has a good anti-adhesion effect.

[0023] Further improved, a main fixing nail 8 is arranged in the middle of the surface of the fixing disk 5. And the first fixing nails 4 and the second fixing nails 7 are of the same size. The size of the main fixing nail 8 is twice that of the first fixing nails 4 and the second fixing nails 7. The main fixing nail 8 and the second fixing nails 7 are secondarily fixed to improve the stability after fixation.

[0024] Further improved, the arrangement arc of the first fixing nails 4 is the same as the arc of the fixing pieces 2. The arc-shaped fixing pieces 2 and the first fixing nails 4 have good tensile performance.

[0025] Working principle: During the hernia repair operation, lift the hernia sac in front of and inside the spermatic cord and make a small incision. After finding the hernia sac, extract the contents in the hernia sac, free and sever the hernia sac, gradually peel the tissue outside the hernia sac, ligate at the high position of the hernia sac neck. The position is initially fixed by the first fixing nails 4. Then, the second fixing nails 7 and the main fixing nails 8 are fixed on the abdominal wall above the extraperitoneal hernia to prevent the hernia repair patch from sliding or moving during the hernia repair operation. The abdominal wall falls and presses to fix the inner repair patch 3 on the extraperitoneal hernia, and the hernia repair operation is completed.
