Abstract

Surgical simulators and methods associated with the same are provided. In one aspect, a surgical simulator includes a rib cage including a plurality of ribs, internal tissue positionable within the rib cage, and external tissue adapted to cover at least a portion of the rib cage. In another aspect, a method of manufacturing a surgical simulator includes forming a rib cage including a plurality of ribs, positioning internal tissue within the rib cage, and at least partially covering the rib cage with external tissue. In a further aspect, a method of modifying biologic tissue for use with a surgical simulator is provided.

First claim

The invention claimed is:

1. A surgical simulator capable of being used to simulate surgery on tracheoesophageal fistula from a right portion of a rib cage sized and shaped to replicate a neonate, the surgical simulator comprising:
at least a portion of a sternum sized and shaped to replicate at least a portion of a neonate sternum;
a right portion of a rib cage extending from the sternum and including a first plurality of right ribs, wherein the right portion of the rib cage includes a removable portion including a second plurality of right ribs less than the first plurality of right ribs, wherein the right portion of the rib cage and the right ribs are sized and shaped to replicate a right portion of a rib cage and right ribs of a neonate;
a right scapula coupled to the right portion of the rib cage, wherein the right scapula is sized and shaped to replicate a right scapula of a neonate;
internal tissue positionable within the right portion of the rib cage, wherein the internal tissue represents a tracheoesophageal fistula; and
external tissue adapted to cover at least a portion of the right portion of the rib cage.

2. The surgical simulator of claim 1 , further comprising a right clavicle, wherein the right clavicle is sized and shaped to replicate a right clavicle of a neonate.

3. The surgical simulator of claim 1 , wherein the second plurality of right ribs includes five right ribs.

4. The surgical simulator of claim 1 , wherein the removable portion includes the second plurality of right ribs and a portion of the at least a portion of the sternum.

5. The surgical simulator of claim 1 , wherein the removable portion includes at least one projection and the at least a portion of the sternum includes at least one aperture, wherein the projection and the aperture selectively cooperate to removably couple the removable portion to the at least a portion of the sternum.

6. The surgical simulator of claim 1 , wherein the internal tissue is internal biologic tissue, and wherein the internal biologic tissue is modified from its original configuration to represent tracheoesophageal fistula.

7. The surgical simulator of claim 6 , wherein the original configuration of the internal biologic tissue is second trimester fetal bovine mediastinal tissue.

8. The surgical simulator of claim 7 , wherein the second trimester fetal bovine mediastinal tissue includes a heart, lungs, an aorta, a trachea and an esophagus.

9. The surgical simulator of claim 8 , wherein the esophagus is transected at a level of a carina and purse-string sutured to a posterior of the carina, wherein a proximal end of the esophagus is shortened about one centimeter and then purse-string closed, wherein an esophageal gap is provided and is about two centimeters.

10. The surgical simulator of claim 1 , wherein the internal tissue includes an esophagus with a proximal end of the esophagus ending in a blind pouch and a distal end of the esophagus being attached to a posterior trachea at a level of a carina.

11. The surgical simulator of claim 10 , wherein the carina is located at a fifth rib of the plurality of first right ribs.

12. A surgical simulator capable of being used to simulate surgery on duodenal atresia of a neonate, the surgical simulator comprising:
a rib cage including a plurality of right ribs and a plurality of left ribs, wherein the rib cage, the right ribs, and the left ribs are sized and shaped to replicate a rib cage, right ribs, and left ribs of a neonate;
a pelvis, wherein the pelvis is sized and shaped to replicate a pelvis of a neonate, and wherein the rib cage and the pelvis define at least a portion of an abdomen, and wherein the at least a portion of an abdomen is sized and shaped to replicate at least a portion of an abdomen of a neonate;
a base defining a first receptacle configured to receive at least a portion of the right ribs and a second receptacle configured to receive at least a portion of the left ribs, wherein, with the at least a portion of the right ribs and the at least a portion of the left ribs at least partially positioned in the first and second receptacles, the rib cage is supported and inhibited from movement, wherein the base defines a third receptacle configured to receive a first end of the pelvis and a fourth receptacle configured to receive a second end of the pelvis, wherein, with the right and left ends of the pelvis positioned in the third and fourth receptacles, the pelvis is supported and inhibited from movement;
internal tissue at least partially positionable within the rib cage, wherein the internal tissue represents duodenal atresia; and
external tissue adapted to cover at least a portion of the rib cage.

13. The surgical simulator of claim 12 , wherein the internal tissue is internal biologic tissue, and wherein the internal biologic tissue is modified from its original configuration to represent duodenal atresia.

14. The surgical simulator of claim 12 , further comprising at least a portion of a sternum connecting the plurality of right ribs and the plurality of left ribs, wherein the at least a portion of a sternum is sized and shaped to replicate at least a portion of a sternum of a neonate.

15. A surgical simulator capable of being used to simulate a lobectomy from a left portion of a neonate rib cage, the surgical simulator comprising:
at least a portion of a sternum sized and shaped to replicate at least a portion of a neonate sternum;
a left portion of a rib cage extending from the sternum and including a first plurality of left ribs, wherein the left portion of the rib cage includes a removable portion including a second plurality of left ribs less than the first plurality of left ribs, wherein the left portion of the rib cage and the left ribs are sized and shaped to replicate a left portion of a rib cage and left ribs of a neonate;
a left scapula coupled to the left portion of the rib cage, wherein the left scapula is sized and shaped to replicate a left scapula of a neonate;
internal tissue positionable within the left portion of the rib cage;
external tissue adapted to cover at least a portion of the left portion of the rib cage; and
a tissue stabilizer coupled to the rib cage for engaging the internal tissue.

16. The surgical simulator of claim 15 , further comprising a left clavicle, wherein the left clavicle is sized and shaped to replicate a left clavicle of a neonate.

17. The surgical simulator of claim 15 , wherein the second plurality of left ribs includes four left ribs.

18. The surgical simulator of claim 15 , wherein the removable portion includes the second plurality of left ribs and a portion of the at least a portion of the sternum.

19. The surgical simulator of claim 15 , wherein the removable portion includes at least one projection and the at least a portion of the sternum includes at least one aperture, wherein the projection and the aperture selectively cooperate to removably couple the removable portion to the at least a portion of the sternum.

20. The surgical simulator of claim 15 , wherein the internal tissue is internal biologic tissue, and wherein the internal biologic tissue is modified from its original configuration to represent a congenital anomaly.

21. A surgical simulator capable of being used to simulate surgery on diaphragmatic hernia of a neonate, the surgical simulator comprising:
at least a portion of a sternum sized and shaped to replicate at least a portion of a neonate sternum;
a rib cage defining a cavity therein and includ
