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 an inner surface, an outer surface, and at least one opening;
a simulated removable tissue model including a simulated uterus positioned within the enclosure of the simulated pelvis; and
an adapter attached at the at least one opening of the simulated pelvis, the adapter configured to simulate a vagina for vaginal surgery.

2. The surgical simulator of claim 1 , wherein the simulated pelvis comprises a cylindrical-shaped frame defining the enclosure having the inner surface, the outer surface, and the at least one opening.

3. The surgical simulator of claim 2 , wherein the cylindrical- shaped frame comprises a sheet comprising:
two curved portions corresponding to simulated left and right illium or iliac crests,
a first protrusion corresponding to a simulated sacrum,
a second protrusion corresponding to a simulated coccynx,
a first lower lobe corresponding to a simulated left ischium,
a second lower lobe corresponding to a simulated right ischium, and
a first and a second aperture corresponding to a simulated obturator foramen.

4. The surgical simulator of claim 3 , wherein the first lower lobe and the second lower lobe are joined together.

5. The surgical simulator of claim 3 , wherein the first lower lobe and the second lower lobe are spaced apart a pre-determined distance.

6. The surgical simulator of claim 3 , wherein a location where the first lower lobe and the second lower lobe are joined corresponds to a simulated pubic bone symphysis.

7. The surgical simulator of claim 3 , wherein the first lower lobe and the second lower lobe are maintained in a pre-determined configuration using clips and wires.

8. The surgical simulator of claim 7 , wherein the pre-determined configuration corresponds to an upward orientation with the cylindrical-shaped frame.

9. The surgical simulator of claim 8 further comprising a trainer configured to simulate a body cavity and house the cylindrical-shaped frame therein, wherein the clips and wires are configured to be connected between the cylindrical-shaped frame and the trainer.

10. The surgical simulator of claim 2 , wherein the cylindrical-shaped frame is compressible and configured to retain its shape after bending.

11. The surgical simulator of claim 2 , further comprising webbing, wherein the webbing is configured to attach and suspend the simulated removable tissue model within the cylindrical-shaped frame.

12. The surgical simulator of claim 1 , wherein the adapter comprises a plate having an outer surface, an inner surface and an aperture, the inner surface facing towards the enclosure of the frame and the aperture extending through the plate from the inner surface to the outer surface of the plate.

13. The surgical simulator of claim 1 further comprising a first sheet attached to an anterior of the simulated uterus and a second sheet attached to a posterior of the simulated uterus, the first sheet being folded to simulate a vesico-uterine fold and the second sheet being folded to simulate a recto-uterine fold.

14. A surgical simulator for surgical training comprising:
a simulated pelvis defining an enclosure having an inner surface, an outer surface, and at least one opening;
a simulated uterus positioned within the enclosure of the simulated pelvis;
a first sheet attached to an anterior of the simulated uterus, the first sheet being folded to simulate a vesico-uterine fold; and
a second sheet attached to a posterior of the simulated uterus, the second sheet being folded to simulate a recto-uterine fold.

15. The surgical simulator of claim 14 further comprising an adapter attached to the at least one opening of the simulated pelvis and a trainer configured to house the simulated pelvis therein.
