The internal (deep) inguinal ring is the abdominal opening of the inguinal canal. The ring transmits the spermatic cord (or round ligament) and is the site at which an indirect inguinal hernia first develops, when the persistent vaginal process or peritoneal extension protrudes through. In laparoscopic inguinal hernia repair (LIHR), correct closure of the peritoneum at the internal ring is a defining technical step. The pediatric LIHR trainer described by Duboureau et al. uses the neck of a plastic bottle of more than one litre as a geometric proxy for the ring — the bottle-neck calibre approximates the diameter of an infant's deep ring and provides a fixed boundary for simulated intracorporeal knotting.

Plastic-bottle neck Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) Neck of the plastic bottle. The bottle-neck calibre was selected because it mimicked the internal inguinal ring; smaller bottles were tested and rejected because the mouth size did not resemble the infant's anatomy.[1]
