A one-piece artificial mesh larger than the hernia gap is used to repair and strengthen the damaged abdominal wall gap. The overall structure includes the upper and lower artificial meshes and a connecting central axis. The central axis of the mesh is used to block the hernia gap. The upper and lower layers of artificial mesh can be pasted on the inner and outer sides of the damaged abdominal wall. The anti-pressure principle of dam repair is used to strengthen the anti-pressure, which can block the pressure of the abdominal wall and will not increase the tension of the abdominal wall, reducing the possibility of postoperative pain and recurrence. sex. After three years of tracking, the recurrence rate of patients using tension-free three-in-one artificial mesh is less than 0.05%, and it has the advantages of short operation time, low pain, and fast recovery speed. Usually, patients only need to be hospitalized after surgery. 1-2 days, you can quickly return to normal work and life. This operation is a self-funded project.
