Abstract

Embodiments of the present invention provide GYN pathology simulation models for surgical training. These models are energy-compatible models emulating the tissue-based diseases of the female reproductive system to allow the surgical trainees and surgeons to practice advanced OB/GYN surgical skills. One simulated GYN model includes an electrically conductive elongated tube encapsulating a mass of non-conductive material. The elongated tube having a sidewall with an inner surface and outer surface extending between a proximal end and distal end. The sidewall is configured to have a cavity with a specific volume to yield an external protuberance when filled with the mass of non-conductive material. Another simulated GYN model includes a fluid-filled cystic body encapsulated within an electrically conductive bulbous hollow structure. The fluid-filled cystic body is selectively adhered to the bulbous hollow structure in at least one or more regions, thereby creating a plane for a combination of blunt and sharp dissection.

Claims (26)

1 . A gynecology pathology surgical simulation system comprising:

a fluid-filled cystic body encapsulated within a bulbous hollow structure having a proximal elongation at a proximal end and a distal elongation at a distal end,

wherein the fluid-filled cystic body is selectively adhered to the bulbous hollow structure in at least one or more regions of an interface between the fluid-filled cystic body and the bulbous hollow structure, thereby creating a plane for a combination of blunt and sharp dissection, and

wherein the fluid-filled cystic body is coated with a thickening agent in the at least one or more regions of the interface between the fluid-filled cystic body and the bulbous hollow structure to create multiple sites of fragile adhesions.

2 . The surgical simulation system of claim 1 wherein the bulbous hollow structure is made of electrically conductive material.

3 . The surgical simulation system of claim 1 wherein the at least one or more regions of the interface between the fluid-filled cystic body and the bulbous hollow structure are adhered using a low bond strength adhesive to create multiple sites of fragile adhesions.

4 . The surgical simulation system of claim 1 wherein the proximal elongation of the bulbous hollow structure has a first length and the distal elongation of bulbous hollow structure has a second length; the second length being greater than the first length.

5 . The surgical simulation system of claim 1 wherein the fluid-filled cystic body is adhered at one location to the bulbous hollow structure using a high strength adhesive to create a single site of strong adhesion.

6 . The surgical simulation system of claim 1 wherein the one location defines a base of the fluid-filled cystic body and is placed proximate to the proximal elongation.

7 . The surgical simulation system of claim 1 wherein the fluid-filled cystic body is made from a diluted ratio of platinum-cured silicone thermoset.

8 . The surgical simulation system of claim 1 wherein the fluid-filled cystic body is made from a solution made of silicone and Novocs® silicone solvent.

9 . The surgical simulation system of claim 1 wherein the fluid-filled cystic body is filled with water.

10 . The surgical simulation system of claim 1 wherein the fluid-filled cystic body is filled with liquid or fluid mixed with colorants to achieve realistic appearance.

11 . A gynecology pathology surgical simulation system comprising:

a fluid-filled cystic body encapsulated within a bulbous hollow structure having a proximal elongation at a proximal end and a distal elongation at a distal end,

wherein the fluid-filled cystic body is selectively adhered to the bulbous hollow structure in at least one or more regions of an interface between the fluid-filled cystic body and the bulbous hollow structure, thereby creating a plane for a combination of blunt and sharp dissection, and

wherein the fluid-filled cystic body is coated with a thickening agent in the at least one or more regions of the interface between the fluid-filled cystic body and the bulbous hollow structure to create multiple sites of fragile adhesions; the thickening agent comprising cornstarch.

12 . The surgical simulation system of claim 11 wherein the bulbous hollow structure is made of electrically conductive material.

13 . The surgical simulation system of claim 11 wherein the at least one or more regions of the interface between the fluid-filled cystic body and the bulbous hollow structure are adhered using a low bond strength adhesive to create multiple sites of fragile adhesions.

14 . The surgical simulation system of claim 11 wherein the proximal elongation of the bulbous hollow structure has a first length and the distal elongation of bulbous hollow structure has a second length; the second length being greater than the first length.

15 . The surgical simulation system of claim 11 wherein the fluid-filled cystic body is adhered at one location to the bulbous hollow structure using a high strength adhesive to create a single site of strong adhesion.

16 . The surgical simulation system of claim 15 wherein the one location defines a base of the fluid-filled cystic body and is placed proximate to the proximal elongation.

17 . The surgical simulation system of claim 11 wherein the fluid-filled cystic body is made from a diluted ratio of platinum-cured silicone thermoset.

18 . The surgical simulation system of claim 11 wherein the fluid-filled cystic body is made from a solution made of silicone and Novocs® silicone solvent.

19 . The surgical simulation system of claim 11 wherein the fluid-filled cystic body is filled with water.

20 . The surgical simulation system of claim 11 wherein the fluid-filled cystic body is filled with liquid or fluid mixed with colorants to achieve realistic appearance.
