Background
Hernia is one of the common surgical diseases, meaning that human tissues or organs protrude to another place through physiological or pathological defects or weaknesses. Clinically, it can be classified into inguinal hernia, umbilical hernia, incisional hernia, white line hernia, lumbar hernia, etc., and diaphragmatic hernia, hiatal hernia, pelvic hernia, etc. occurring in the abdominal cavity or chest cavity. At present, the operation is the only reliable method for radically curing hernia. Laparoscopic inguinal hernia repair is an emerging technique developed in recent years to treat inguinal hernias, with the ability to place the patch deeper laparoscopically than traditional open tension-free repair, reducing recurrence rate. Meanwhile, the medical device has the advantages of attractive appearance, small wound, small postoperative pain and the like, and is greatly popularized and applied clinically in recent years.
Patent document CN106562836a discloses a hernia patch for treating inguinal hernia by laparoscopic patch implantation, but after the cone is filled in the hernial annular mouth, the cone is easy to squeeze and agglomerate to form a large number of small cavities, so that phagocytes cannot pass through, interstitial fluid is accumulated, and inflammation and seroma are caused.
