The only way to cure inguinal hernia is surgery, so patients with hernia should go to a regular hospital for surgical treatment. Surgical treatment can be divided into two types: traditional tensioned surgical treatment and tension-free hernia repair, of which tension-free hernia repair is divided into open tension-free hernia repair and laparoscopic tension-free hernia repair. The traditional surgical treatment relies on the surrounding tissue to forcibly close the hernia hole, which results in significant postoperative pain, slow recovery and high recurrence rate. The synthetic material (commonly known as patch) is the only biological implant material that meets the eight criteria for implant materials.
