The specific steps of laparoscopic hernia repair are as follows: 1. Establish a peritoneal puncture hole, usually a 1 cm peritoneal exploration puncture hole is taken at the navel and a 5 mm laparoscopic operation hole is taken at the external edge of the rectus abdominis muscle on both sides. 2. After entering the abdominal cavity, a 5-6 m incision is made in a 2 cm arc above the internal ring orifice defect to avoid damaging the subabdominal vessels when opening the peritoneum. 3. Separate the hernia sac completely, and in the process of separating the hernia sac and the spermatic cord Pay attention to protect the vas deferens and spermatic cord vessels to avoid injury. For patients with large hernia sacs, the hernia sac can be transected to avoid postoperative complications such as scrotal edema.4. Free the anterior peritoneal space, medially reaching the pubic bladder space and laterally reaching the anterior superior iliac spine space.5. Place the mesh properly in the anterior peritoneal space and give sutures to fix it to avoid sliding of the mesh.6. Suture the opened peritoneal defect and exit the puncture hole to ensure that there is no bleeding on the trauma, and the operation is finished.
