Tension-free hernia repair utilizes a one-piece artificial mesh that is larger than the hernia notch to repair and strengthen the damaged abdominal wall notch. The overall structure includes two layers of artificial mesh and a connecting center shaft, which is used to block the hernia notch, and the upper and lower layers of artificial mesh can be affixed to the damaged abdominal wall on the inner and outer sides. It can stop the pressure on the abdominal wall and will not cause the abdominal wall to increase in tension, which reduces postoperative pain and the possibility of recurrence. After three years of tracking, the recurrence rate of patients using the tension-free 3-in-1 mesh is less than 0.05%, and has the advantages of short operation time, low pain, and fast recovery. Usually, patients only need to be hospitalized for 1-2 days after the operation, and they can return to their normal work and life quickly. This surgery is a medical insurance reimbursement program.
