Tension-free hernia repair: Principle of surgery: A one-piece mesh larger than the hernia notch is used to repair and strengthen the damaged abdominal wall notch, and the overall structure consists of two layers of artificial mesh and a connecting central shaft, the central shaft of the mesh is used to plug the hernia notch, the upper and lower layers of artificial mesh can be applied to the inside and outside of the damaged abdominal wall, and the pressure resistance principle of dam repair is applied to strengthen the pressure resistance, which can block the pressure of the abdominal wall. It will not lead to an increase in abdominal wall tension, reducing the possibility of postoperative pain and recurrence for patients. After three years of follow-up, the recurrence rate of patients using the tension-free 3-in-1 artificial mesh is less than 0.05%, and it has the advantages of short operation time, low pain and fast recovery. This procedure is reimbursed by medical insurance. Lightweight Partially Absorbable Mesh is a new type of mesh developed using modern technology, which originated in Europe and can be used in the treatment of inguinal hernia. The main features are partially absorbable material and large holes, which allow for less foreign body residue and easier formation of a more elastic crust tissue that fits the abdominal wall structure. With conventional hernia mesh, patients often complain of chronic pain due to limited abdominal wall mobility or a foreign body sensation of the mesh. However, the larger holes and partially absorbable material allow for a lighter quality artificial mesh that reduces the amount of mesh in the body and reduces the inflammatory tissue reaction caused by the mesh after implantation.
