Abstract
A model for practicing transabdominal pre-peritoneal (TAPP) and total extraperitoneal (TEP) 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.
