1. A simulated tissue structure for surgical training, comprising:
a first layer of silicone polymer with an upper surface and a lower surface defining a thickness therebetween;
a second layer of silicone polymer with an upper surface and lower surface defining a thickness therebetween; the second layer being spaced apart from the first layer defining a gap therebetween such that the upper surface of the first layer faces the lower surface of the second layer;
an inclusion located between the first layer and the second layer; and
a third layer made of a plurality of entangled fibers located between the first layer and the second layer; the plurality of entangled fibers residing within the gap in a randomly arranged fashion such that part of the plurality of entangled fibers is embedded in both the first layer and second layer to create a mechanical linkage of fiber connecting the first layer and the second layer, thereby providing a dissection plane for practicing surgical excision of the inclusion.
