Abstract
A simulated abdominal wall model that is ideal for practicing laparoscopic first entry surgical techniques is provided. The model includes a simulated abdominal wall portion captured between two frame elements of a support. The support is connectable to a surgical trainer. When connected to the trainer, the model provides a penetrable abdominal tissue portion for accessing an internal cavity of the trainer. The simulated abdominal wall includes a plurality of layers including a skin layer, a fabric posterior rectus sheath layer, a simulated fat layer of low-resilience polyurethane foam and at least two layers that provide distinctive haptic feedback upon penetration of the simulated transversalis fascia and muscle layers. The simulated abdominal wall includes a simulated umbilicus across several layers of simulated tissue.
