Tension-free hernia repair is one of the most commonly used surgical modalities for the treatment of hernia, and the specific steps are generally as follows: First, the patient takes a lying position after satisfactory lumbar-rigid combined anesthesia, and the inguinal area is routinely disinfected and covered with a sterile towel. Second, in the anterior superior iliac spine to the pubic tuberosity line two centimeters above the midpoint of the oblique incision, layer by layer incision of the skin, subcutaneous tissues, revealing the patient’s hernia sac, the inner ring mouth, the spermatic cord and other tissues. Separate the adhesion between the hernia sac and the spermatic cord, and return the hernia sac into the abdominal cavity completely. Fourth, reconstruct the internal ring, implant the patch into the transversus abdominis fascia anteriorly, reinforce the posterior wall of the inguinal canal and fix the patch properly, stop the bleeding of the wound thoroughly, suture the external oblique abdominal tendon membrane, subcutaneous adipose tissue, and skin layer by layer, and then finish the surgery.
