Abstract

A surgical simulator is disclosed herein. The surgical simulator includes an artificial organ and an enclosure substantially enclosing the artificial organ. The artificial organ is substantially formed of platinum cured room temperature vulcanization silicone rubber (“PCRTVS”).

First claim

What is claimed is:

1. A surgical simulator comprising:
an artificial organ substantially formed of platinum cured room temperature vulcanization silicone rubber (“PCRTVS”); and
an enclosure substantially enclosing the artificial organ,
wherein the artificial organ comprises at least one lumen substantially formed of PCRTVS.

2. The surgical simulator of claim 1 , wherein the at least one lumen generally imitates a vascular inflow and outflow tract segmented according to Couinaud's classification.

3. The surgical simulator of claim 1 , wherein the artificial organ comprises an artificial liver, and the at least one lumen generally imitates a biliary drainage tract segmented according to Couinaud's classification.

4. The surgical simulator of claim 1 , further comprising fluid pressurizing means configured to fluidly pressurizing the at least one lumen.

5. The surgical simulator of claim 4 , wherein, the fluid pressurizing means comprises at least one of a pumping mechanism or a fluid reservoir.

6. The surgical simulator of claim 4 , further comprising an element that facilitates determining an amount of fluid lost via an opening created in the at least one lumen.

7. A surgical simulator comprising:
an artificial organ substantially formed of platinum cured room temperature vulcanization silicone rubber (“PCRTVS”); and
an enclosure substantially enclosing the artificial organ,

wherein the artificial organ is substantially formed of a mixture comprising a ground cured PCRTVS mixed with a liquid PCRTVS that is then allowed to cure.

8. The surgical simulator of claim 7 , wherein the ground cured PCRTVS includes at least one of a ground cured PCRTVS durometer Shore A10, a ground cured PCRTVS durometer Shore OO3, or a ground cured PCRTVS durometer Shore OO10.

9. The surgical simulator of claim 8 , wherein the liquid PCRTVS comprises a PCRTVS durometer Shore OO30.

10. The surgical simulator as in any of claim 1 or 7 , in which the artificial organ comprises an artificial ovarian organ.

11. The surgical simulator of claim 10 , wherein the artificial ovarian organ comprises an ovary portion formed of one type of PCRTVS and a uterine horn portion formed of another type of PCRTVS.

12. The surgical simulator of claim 11 , wherein the ovarian portion is substantially formed of PCRTVS durometer Shore A10, and the uterine horn portion is substantially formed of PCRTVS durometer Shore OO10.

13. The surgical simulator of claim as in any of claim 1 or 7 , wherein the artificial organ comprises a first portion formed of one type of PCRTVS and a second portion formed of another type of PCRTVS.

14. The surgical simulator of claim 13 , wherein the first portion is substantially formed of PCRTVS durometer Shore A10, and the second portion is substantially formed of PCRTVS durometer Shore OO10.

15. The surgical simulator as in any of claim 1 or 7 , in which the artificial organ comprises an artificial liver organ.

16. The surgical simulator as in any of claim 1 or 7 , in which the artificial organ comprises an artificial spleen organ.

17. The surgical simulator as in any of claim 1 or 7 , in which the enclosure comprises an exterior wall including surgical access openings defined therein.

18. The surgical simulator of claim 17 , wherein the surgical access openings are configured for laparoscopic surgical instruments.

19. The surgical simulator of claim 17 , further comprising an organ support assembly configured to removably support the artificial organ within the enclosure.

20. The surgical simulator of claim 17 , wherein the exterior wall comprises an artificial body wall substantially formed of different layers of PCRTVS.

21. The surgical simulator of claim 20 , wherein the artificial body wall is vascularized with a plurality of lumens substantially formed of PCRTVS.

22. The surgical simulator of claim 21 , further comprising pressurizing means configured to fluidly pressurizing the plurality of lumens that vascularize the artificial body wall, the pressurizing means comprising at least one of a pumping mechanism or a fluid reservoir.

23. The surgical simulator of claim 22 , further comprising an element that facilitates determining an amount of fluid lost via an opening created in the plurality of lumens that vascularize the artificial body wall.
