Abstract

A laparoscopic trainer platform assembly includes: a training platform; a base, configured to accommodate at least one target array; the target array including a planar surface upon which are disposed a plurality of protruding targets oriented at various angles on the base; a left side support for supporting the training platform on the base; and a right side support for supporting the training platform on the base.

Claims

1. A system suitable for use in surgical skills training, said system comprising:

a trainer platform assembly including;

a training platform, wherein said training platform has one or more openings, wherein at least one said opening is configured for at least an endoscopic opening;

a base, said base configured to accommodate at least one target array;

said target array including a planar surface upon which are disposed a plurality of protruding targets oriented at a plurality of angles on said base;

a left side support for supporting said training platform on said base; and

a right side support for supporting said training platform on said base such that said training platform, said base, and said left and right side supports define a working volume; and

a training endoscope for extending into said working volume by passing through said endoscopic opening, wherein said training endoscope includes;

an endoscope housing and a viewing barrel, said viewing barrel having a barrel axis, a first end secured to said endoscope housing, a second end having a skewed barrel end, and an inner barrel slidably retained within said viewing barrel, wherein said inner barrel has a first end, a second end, and a length longer than that of said viewing barrel; and

a video electronic module connected to said first end of said inner barrel, a video camera connected to said second end of said inner barrel, wherein said video electronic module is connected to said video camera, said video electronic module configured to transmit from said video camera to a display device an electronic image with electronically-generated cross hairs and a countdown time value superimposed on said electronic image, and wherein said second end of said inner barrel extends beyond said second end of said viewing barrel to align said video camera with said barrel axis, and moving rearward said inner barrel to position said second end of said inner barrel within said viewing barrel causes said video camera to swivel relative to said second end of said viewing barrel so as to provide a viewing axis that can be varied from zero degrees to thirty degrees with respect to said barrel axis.

2. The system of claim 1, wherein said working volume comprises one or more of a suture block, a foam organ with at least one appendage, a dexterity peg board, a single-circle gauze pad, and a double-circle gauze pad.

3. The system of claim 1, wherein said video camera is rotatable 360 degrees at said viewing axis and said skewed barrel end is 30 degrees from an axis perpendicular to said barrel axis.

4. The system of claim 1, wherein said target array is a thirty-degree target array for use with said viewing axis at thirty degrees with respect to said barrel axis, wherein said thirty-degree target array includes said plurality of protruding targets each situated on a respective raised feature, and wherein said thirty-degree target array includes a plurality of respective cowls positioned so as to prevent a direct view of each respective protruding target from said endoscope opening.

5. The system of claim 4, wherein said thirty-degree target array is vacuum and heat formed from a plastic sheet, and further includes a finger hole to enable a user to remove said thirty-degree target array from within said base.

6. The system of claim 1, wherein said target array is a zero-degree target array for use with said viewing axis at zero degrees with respect to said barrel axis, and wherein said zero-degree target array is vacuum and heat formed from a plastic sheet, and includes said plurality of protruding targets each situated on a respective raised feature.

7. The system of claim 6, wherein said zero-degree target array further includes a finger hole to enable a user to remove said zero-degree target array from within said base.

8. The system of claim 1, further comprising a simulated skin layer disposed on said training platform.

9. The system of claim 8, wherein said simulated skin layer includes at least one cut-thru configured for said training endoscope to extend through said cut-thru and into said working volume via said endoscope opening.

10. The system of claim 1, wherein said electronically-generated cross hairs define an electronically-generated target, said electronically-generated target configured such that a user can operate said training endoscope so as to electronically superimpose said electronically-generated target on one of said plurality of protruding targets on said base appearing in said electronic image.

11. The system of claim 1, wherein said video electronic module further comprising a countdown timer displayed on said display device.

12. The system of claim 1, further comprising at least one of a pre-tied ligating loop and a reusable endoloop that can be placed around an appendage of a foam organ using a grasper.

13. The system of claim 1, wherein said inner barrel further includes at least one detent positioned approximately near said second end of said inner barrel so as to provide guidance for setting said viewing axis at a desired angle with respect to said barrel axis.

14. The system of claim 1, wherein said training endoscope further includes a detent configured for setting said viewing axis to zero degrees with respect to said barrel axis.

15. The system of claim 1, wherein said training endoscope further includes a detent configured for setting said viewing axis to thirty degrees with respect to said barrel axis.

16. The system of claim 1, wherein said training platform further comprising at least one grasper port suitable for allowing at least one grasper to extend into said working volume by passing through said at least one grasper port.

17. The system of claim 1, further comprising a cannulation fixture disposed on said base, wherein said cannulation fixture includes a cannulation tube, a cannulation base, a first clamp, and a second clamp, wherein said cannulation tube is secured to said cannulation base by said first clamp and said second clamp, and wherein said cannulation tube has a cannulation tube opening.

18. The system of claim 17, further comprising a catheter configured for insertion into said cannulation tube opening, wherein said catheter includes (i) a flexible, transparent outer tube having at least one open end, and (ii) a metal pin configured for insertion into said open end of said outer tube.

19. The system of claim 18, wherein said metal pin includes a marking string so as to indicate a depth in which said catheter has entered said cannulation tube via said cannulation tube opening.

20. The system of claim 19, wherein said outer tube further includes at least one circumferential line so as to indicate a depth in which said catheter has entered said cannulation tube via said cannulation tube opening, and wherein said circumferential line is ink.

21. The system of claim 2, wherein said foam organ comprises at least two layers of a foam material and a heat-sealed perimeter.

22. The system of claim 1, wherein said working volume comprises a Penrose drain.

23. The system of claim 22, wherein the Penrose drain is made of an elastic material.

24. The system of claim 22, wherein the Penrose drain is configured to be sutured using an extracorporeal knot.

25. The system of claim 22, wherein the Penrose drain is configured to be sutured using an intra-corporeal knot.
