Abstract

A simulated dissectible tissue model for practicing surgical skills is provided. The simulated tissue comprises a simulated anatomical structure, such as one or more artificial vessel, embedded with a silicone gel layer between two silicone layers. The simulated dissectible tissue, with or without a simulated anatomical structure, is connected to one or more artificial organ via a fiberfill layer. The fiberfill layer includes a plurality of entangled fibers embedded between two adjacent silicone layers. The fiberfill layer creates a dissection plane that permits the one or more artificial organ to be removed by spreading apart and selectively dissecting the chains of entangled fibers. Artificial nerves may be included in fiberfill layer.

First claim

We claim:

1. A simulated dissectible tissue structure for surgical training, comprising:
a lower pelvis region model including:
a first cylinder of silicone having an outer surface and an inner surface defining a first lumen;
a second cylinder of silicone having an outer surface and an inner surface defining a second lumen;
a third cylinder of silicone having an outer surface and an inner surface defining a third lumen;
a fourth cylinder of polyfill located between the third cylinder and second cylinder; and
a frame defining an interior and an exterior;
wherein the first cylinder, second cylinder, third cylinder and fourth cylinder are suspended inside the interior of the frame; and first cylinder is located inside the second cylinder and the second cylinder is located inside the third cylinder.

2. The simulated dissectible tissue structure of claim 1 further including a simulated prostate system suspended inside the interior of the frame; the simulated prostate system comprising a simulated prostate, simulated seminal vesicles, simulated bladder, simulated urethra and simulated vas deferens.

3. The simulated dissectible tissue structure of claim 2 wherein the simulated urethra and simulated vas deferens are made of silicone formed into a solid or hollow tube.

4. The simulated dissectible tissue structure of claim 3 wherein the simulated seminal vesicles are made of urethane foam over molded onto the simulated vas deferens.

5. The simulated dissectible tissue structure of claim 3 wherein the simulated prostate is made of urethane foam over molded onto the simulated urethra.

6. The simulated dissectible tissue structure of claim 1 further including a simulated bladder suspended inside the interior of the frame.

7. The simulated dissectible tissue structure of claim 1 further including a simulated prostate suspending inside the interior of the frame.

8. The simulated dissectible tissue structure of claim 1 wherein the interior and exterior of the frame are defined by top and base panels provided respectively on anterior and posterior sides of the lower pelvis region model; the top and base panels being made of plastic and both having one or more fastener location.

9. The simulated dissectible tissue structure of claim 8 wherein the top panel which is located anteriorly is configured to simulate a pubic bone area.

10. The simulated dissectible tissue structure of claim 8 wherein a simulated prostate system is connected to the top panel via connection of one or more fastener with the one or more fastener location.

11. The simulated dissectible tissue structure of claim 8 wherein a simulated rectum is connected to the base panel via connection of one or more fastener with the one or more fastener location; the simulated rectum comprising the first cylinder, second cylinder, third cylinder and fourth cylinder, wherein the second cylinder represents a simulated mesorectum layer.

12. The simulated dissectible tissue structure of claim 11 wherein the one or more fastener is a rivet and the one or more fastener location is a hole sized and configured to receive the rivet.

13. The simulated dissectible tissue structure of claim 12 wherein the rivet is attached to the third cylinder with the fourth cylinder being located inside of the third cylinder serving as an inner layer of polyfill.

14. The simulated dissectible tissue structure of claim 10 wherein the one or more fastener is a rivet and the one or more fastener location is a hole sized and configured to receive the rivet.
