Hysterectomy model
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.
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, wherein the simulated tissue model is suspended within the simulated pelvis via at least one sheet that is attached to an anterior of the simulated uterus; 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 adapter further comprises:
a flat plate having an inner surface facing towards the enclosure of the simulated pelvis and an outer surface facing outwards towards a user, and
an aperture that passes through the flat plate from the inner surface to the outer surface.
3. The surgical simulator of claim 2 , wherein the adapter comprises a tubular extension that extends into the enclosure of the simulated pelvis, the tubular extension having a proximal end located at the inner surface of the flat plate, and wherein a distal end of the tubular extension is configured to receive a tubular structure that attaches to the simulated removable tissue model.
4. The surgical simulator of claim 3 , wherein the tubular structure is the simulated uterus.
5. The surgical simulator of claim 3 , wherein the tubular structure is stretchable, and wherein a portion of the tubular structure is stretched around the distal end of the tubular extension to secure the tubular structure to the adapter.
6. The surgical simulator of claim 3 , wherein the distal end of the tubular extension comprises a radially-extending flange that extends around at least a portion of the tubular extension, the flange configured to secure and retain the simulated removable tissue model.
7. The surgical simulator of claim 2 , wherein the aperture is oriented along a longitudinal axis of the adapter.
8. The surgical simulator of claim 2 , wherein the aperture is oriented perpendicular to a longitudinal axis of the adapter.
9. The surgical simulator of claim 1 , further comprising an external trainer, the external trainer comprising:
a top cover; and
a base spaced apart from the top cover,
wherein the external trainer forms an interior space configured to mimic a body cavity, and wherein the interior space is configured to receive the simulated pelvis.
10. The surgical simulator of claim 9 , wherein the adapter is configured to space apart the top cover to the base of the external trainer.
11. The surgical simulator of claim 10 , wherein the adapter comprises tabs or channels that are configured to connect the adapter with one or more of the top cover or the base of the external trainer.
12. The surgical simulator of claim 9 , wherein the adapter is configured to be positioned between the top cover and the base of the external trainer.
13. The surgical simulator of claim 9 , wherein the adapter has a top portion proximate the top cover and a bottom portion proximate the base.
14. The surgical simulator of claim 9 , wherein the adapter is configured to provide a way for a user to access the simulated pelvis located within the interior space of the external trainer.
15. The surgical simulator of claim 9 , wherein the adapter further comprises a plurality of molding apertures that surround the aperture configured for overmolding a simulated tissue interface onto the adapter.
16. The surgical simulator of claim 2 , wherein the adapter is made of a flexible or soft material to configure the adapter to simulate a practice of retraction by the user.
17. The surgical simulator of claim 2 , wherein the aperture is elongate elliptical oval-like in shape.
18. The surgical simulator of claim 2 , wherein the adapter is made of a rigid material to configure the adapter to simulate an already retracted vaginal canal.
19. The surgical simulator of claim 1 , further comprising a second sheet connected to a posterior of the simulated uterus.
