The inguinal canal is an oblique passage through the lower anterior abdominal wall, traversing the muscular and fascial layers between the deep inguinal ring (internal opening) and the superficial inguinal ring (external opening). It transmits the spermatic cord in males and the round ligament of the uterus in females. The canal is a clinically critical structure in inguinal hernia repair — both the open Lichtenstein and laparoscopic (TAPP, TEP) approaches require detailed understanding of canal anatomy, including the position of the vas deferens, testicular vessels, and the boundaries of the myopectineal orifice. In pediatric laparoscopic inguinal hernia repair (LIHR), simulators frequently represent the canal using inverted plastic-bottle funnels or similar geometric proxies that mimic the oblique trajectory of the canal relative to the abdominal wall.
