Description

Technical Field

[0001] The invention relates to the technical field of tissue repair, and in particular to a tissue repair mesh with a surface micro-anchor structure. Background Art

[0002] Tissue repair mesh is currently recognized worldwide as the most ideal material for replacing and repairing human tissue. Its safety has been verified for many years and is widely used in artificial blood vessels, heart repair and other surgeries. It has ideal effects, is safe and reliable, and can survive permanently. Meshes of different specifications can be selected according to the different needs of patients. After recovery from the operation, the appearance is natural and realistic without scars, foreign body contours or foreign body sensation. Since the principle of biological tissue mesh technology is to implant allogeneic homologous tissue, after a period of recovery, the surgeon's own tissue will automatically merge with this tissue without rejection reaction, and there is no difference from autologous tissue. The biological tissue mesh material has very good compatibility with the surrounding tissue and does not contain any substances harmful to the human body, so the chance of infection is very small.

[0003] Tissue repair mesh is very compatible with the human body's own tissues, can survive permanently, does not affect human tissues and internal nerve functions, does not produce any side effects or complications, and is safe and reliable. The problem with the existing technology is that the current tissue repair mesh does not have a function that is easy to take and put, and the user is required to disassemble the tissue repair mesh layer by layer. At the same time, the tissue repair mesh requires the user to use sutures to fix and sew, which further damages the patient's injured tissue. The operation takes a long time and is relatively dangerous. Summary of the invention
