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 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 sized and shaped to replicate a right portion of a rib cage of a neonate, wherein the right portion of the rib cage extends from the sternum and includes a plurality of right ribs, wherein at least a portion of the plurality of right ribs are removable from the rib cage;
a right scapula sized and shaped to replicate a right scapula of a neonate, wherein the right scapula is coupled to the right portion of the rib cage;
internal tissue positionable within the right portion of the rib cage, wherein the internal tissue represents a congenital anomaly; and
external tissue adapted to cover at least a portion of the right portion of the rib cage, wherein a size and shape of the neonate sternum and rib cage is defined by an inner width of bony thorax at the hemidiaphragem and a width of thorax at inner aspects of eighth ribs.

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

3. The surgical simulator of claim 1 , wherein the at least a portion of the removable plurality of right ribs includes five right ribs.

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

5. 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 a congenital anomaly.

6. The surgical simulator of claim 5 , wherein the original configuration of the internal biologic tissue is second trimester fetal bovine mediastinal tissue.

7. A 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 sized and shaped to replicate a pelvis of a neonate, wherein the pelvis is defined by the direct measurement of the pelvis of the neonate, and wherein the rib cage and the pelvis define at least a portion of an abdomen 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 at least partially positioned in the first receptacle and the at least a portion of the left ribs at least partially positioned in the second receptacle, 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 first end of the pelvis positioned in the third receptacle and the second end of the pelvis positioned in the fourth receptacle, the pelvis is supported and inhibited from movement;
internal tissue at least partially positionable within the rib cage, wherein the internal tissue represents a congenital anomaly; and
external tissue adapted to cover at least a portion of the rib cage.

8. The surgical simulator of claim 7 , 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.

9. The surgical simulator of claim 7 , 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.

10. A surgical simulator comprising:
at least a portion of a sternum sized and shaped to replicate at least a portion of a neonate sternum wherein a size and shape of the neonate sternum is defined by an inner width of bony thorax at the hemidiaphragem;
a left portion of a rib cage sized and shaped to replicate a left portion of a rib cage of a neonate, wherein the left portion of the rib cage extends from the at least a portion of the sternum and includes a plurality of left ribs, wherein the left portion of the rib cage includes a removable portion including at least some of the plurality of left ribs wherein a size and shape of rib cage is defined by a width of thorax at inner aspects of eighth ribs;
a left scapula sized and shaped to replicate a left scapula of a neonate, wherein the left scapula is coupled to the left portion of the rib cage;
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.

11. The surgical simulator of claim 10 , further comprising a left clavicle sized and shaped to replicate a left clavicle of a neonate.

12. The surgical simulator of claim 10 , wherein the removable portion of the left portion of a rib cage includes four left ribs.

13. The surgical simulator of claim 10 , wherein the removable portion also includes a portion of the at least a portion of the sternum.

14. The surgical simulator of claim 10 , 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.

15. The surgical simulator of claim 10 , 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.

16. A 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 sized and shaped to replicate a rib cage of a neonate, wherein a size and shape of the rib cage is defined by a width of thorax at inner aspects of eighth ribs, or a widest internal width of bony thorax and a length of the thoracic spine, wherein the rib cage defines a cavity therein and includes a left portion of the rib cage extending from the sternum in a first direction and a right portion of the rib cage extending from the sternum in a second direction opposite the first direction, wherein the left portion of the rib cage includes a plurality of left ribs and the right portion of the rib cage includes a plurality of right ribs, wherein the left portion of the rib cage includes a removable portion including at least some of the plurality of left ribs;
internal tissue positionable within the cavity defined by the rib cage;
a tissue stabilizer coupled to the rib cage for engaging the internal tissue, wherein the tissue stabilizer includes a first portion and a second portion adapted to be separated from one another; and
external tissue adapted to cover at least a portion of the rib cage.

17. The surgical simulator of claim 16 , further comprising a support member coupled to the rib cage and defining a recess therein, wherein the tissue stabilizer is selectively positionable in the recess to couple the tissue stabilizer to the rib cage.

18. The surgical simulator of claim 17 , wherein the tissue stabilizer is slideable into and out of the recess.
