Simulated dissectible tissue
First Claim
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.

Abstract
A simulated tissue structure for surgical training is provided. The simulated tissue structure includes a first layer made of silicone and a second layer made of silicone interconnected by a third layer made of polyester fiber that is embedded in part in the first layer and in part in the second layer to create a mechanical linkage between the first layer and the second layer. Part of the third layer that is adjacent to the first layer and part of the third layer that is adjacent to the second layer includes fiber strands coated in silicone. An inclusion that mimics an anatomical structure is located between the first layer and the second layer. The third layer of polyester fibers provides a realistic dissection plane for the practice of the surgical excision of the inclusion.
