Abstract

A surgical simulator for surgical training is provided. The simulator includes a frame defining an enclosure and a simulated tissue model located inside an enclosure. The simulated tissue model is adapted for practicing hysterectomies and includes at least a simulated uterus and a simulated vagina. The simulated tissue model is suspending inside the enclosure with two planar sheets of silicone such that the tissue model is located between the two sheets each of which form a fold and are in turn connected to the frame. The frame may be shaped like a cylinder and located inside a cavity of a larger laparoscopic trainer having a penetrable simulated abdominal wall. The tissue model is interchangeable and accessible laterally through an aperture provided in a support leg of the trainer.

First claim

We claim:

1. A surgical simulator for surgical training comprising:
a simulated pelvis defining an enclosure having and inner surface, an outer surface, and at least one opening;
a simulated tissue model including a simulated uterus;
a first sheet of silicone; and
a second sheet of silicone,
the simulated tissue model being suspended by at least one of the first sheet and the second sheet within the enclosure of the simulated pelvis.

2. The surgical simulator of claim 1 wherein the simulated tissue model is connected to and located between the first and second sheets of silicone.

3. The surgical simulator of claim 1 wherein the first sheet and the second sheet are connected to the simulated pelvis.

4. The surgical simulator of claim 1 wherein the simulated uterus further comprises a simulated cervix located inside the simulated uterus.

5. The surgical simulator of claim 4 wherein the simulated cervix is made of a solid high durometer silicone and includes a slit.

6. The surgical simulator of claim 5 wherein the simulated uterus further comprises simulated fallopian tubes connected to simulated ovaries.

7. The surgical simulator of claim 6 wherein the simulated uterus is made of a foam material combined with silicone.

8. The surgical simulator of claim 4 wherein the simulated uterus weighs 300 to 500 grams.

9. The surgical simulator of claim 1 wherein the simulated uterus has a bulbous portion at a distal end connected to a simulated vagina having a tubular portion at a proximal end, the tubular potion having a lumen accessible through the at least one opening of the simulated pelvis.

10. The surgical simulator of claim 1 further comprising a simulated colon that is located within the enclosure of the simulated pelvis.

11. The surgical simulator of claim 10 wherein the simulated pelvis is cylindrical, and wherein the inner surface is interconnected to the outer surface.

12. The surgical simulator of claim 11 wherein the simulated colon being is laid on the inner surface along a vertical axis of the simulated pelvis.

13. The surgical simulator of claim 12 wherein the simulated tissue model further comprises a simulated bladder located within the enclosure of the simulated pelvis.

14. The surgical simulator of claim 13 further comprising at least one of the first sheet of silicone or the second sheet of silicone connected to the simulated bladder and the simulated pelvis pelvic frame, the simulated bladder is disposed between the at least one of the first sheet of silicone or the second sheet of silicone and the simulated pelvis.

15. The surgical simulator of claim 13 wherein the simulated bladder is connected to the inner surface along the vertical axis of the simulated pelvis.

16. The surgical simulator of claim 1 wherein the simulated pelvis is compressible.

17. The surgical simulator of claim 16 wherein the simulated pelvis is made of a flexible foam material.

18. The surgical simulator of claim 1 wherein the simulated 1 includes one or more cutouts extending between the inner surface and the outer surface.

19. The surgical simulator of claim 10 further comprising a webbing connected to the simulated pelvis and the simulated tissue model, wherein the webbing further suspends the simulated tissue model within the enclosure of the simulated pelvis.
