1. A simulated tissue structure for surgical training, comprising:

  • a first layer of silicone polymer with an upper surface and a lower surface;

    a second layer of silicone polymer with an upper surface and lower surface;

    the second layer being spaced apart from the first layer such that the upper surface of the first layer faces the lower surface of the second layer; and

    a third layer made of a plurality of entangled fiber located between the first layer and the second layer;

    the third layer being embedded in the upper surface of the first layer;

    a fourth layer made of a plurality of entangled fiber located between the first layer and the second layer;

    the fourth layer being embedded in the second layer at the lower surface of the second layer; and

    a first inclusion located between the third layer and the fourth layer; and

    a second inclusion attached to the third layer at the lower surface of the third layer;

    such that the third layer defines an embedded portion that is partially embedded in the second inclusion and an extending portion that extends from the lower surface of the third layer;

    the extending portion being embedded in the first layer at the upper surface of the first layer.
