a model for practicing transabdominal pre - peritoneal and total extraperitoneal approaches for laparoscopic hernia repairs is provided . the model simulates an insufflated space between the abdominal muscles and peritoneum . a spring layer may be incorporated to provide a realistic resiliency to the model while in the simulated insufflated configuration . at least one hole is provided in the model from which synthetic tissue protrudes to simulate a hernia . the model is used to selectively simulate direct , indirect and femoral inguinal hernias as well as incisional hernias by removably placing the protruding simulated tissue into any one of several openings . the model contains all important anatomical structures and sits on a base frame or is connected to a rigid simulated pelvis . when located inside a laparoscopic trainer with an angled top cover , the model provides an ideal simulation for teaching and practicing laparoscopic hernia repair .
