A surgical simulation system for demonstrating a laparoscopic surgical instrument includes a frame defining an internal cavity for supporting an object simulative of human tissue. A wall is coupled to the frame and obstructs a view of the cavity from a surgical vantage point. The wall is constructed of three adjacent layers including an outer layer simulative of skin tissue coupled to the frame by a first fastener, an intermediate layer, and an inner layer simulative of abdominal tissue. The inner layer is coupled to the intermediate layer by a second fastener such that the inner layer is removable from the intermediate layer independently of the outer layer. At least one aperture is defined through the wall to provide entry of the endoscopic surgical instrument into the cavity. A camera captures images from within the cavity transmits the images to a monitor visible from the surgical vantage point.
