Abstract

A prosthetic limb has an outer surface that is a mirror image of an intact limb. The intact limb is scanned and the surface data is manipulated to create a virtual mirror image. The end of the amputated limb is also scanned to obtain socket data. A virtual limb is designed using a computer program based upon the mirror image and end of the amputated limb data. The computer program is also used to design a removable fairing that provides color and texture to the prosthetic limb.

Claims (45)

1. A method for creating a prosthetic limb comprising:

obtaining surface data for an intact limb;

creating a prosthetic limb design having an outer surface that corresponds to a mirror image of the surface data;

producing limb fabrication data and fairing fabrication data from the prosthetic limb design;

using the limb fabrication data, fusing a plurality of material particles together to form the prosthetic limb; and

using the fairing fabrication data to fabricate a fairing, an inner surface of the fairing fitting around the outer surface of the prosthetic limb that corresponds to the mirror image of the surface data.

2. The method of claim 1 further comprising:

applying a metal layer to an outer surface of the fairing.

3. The method of claim 1 further comprising:

applying a colored layer to an outer surface of the fairing.

4. The method of claim 1 further comprising:

applying a colored dye to an outer surface of the fairing.

5. The method of claim 1 further comprising:

applying a metal layer to an outer surface of the prosthetic limb.

6. The method of claim 1 further comprising:

applying a colored layer to an outer surface of the prosthetic limb.

7. The method of claim 1 wherein the prosthetic limb design includes a framework having a plurality of openings.

8. The method of claim 1 wherein the fairing is discontinuous, the fairing covering a first portion of the prosthetic limb and not covering a second portion of the prosthetic limb.

9. The method of claim 1 further comprising:

covering a first portion of the prosthetic limb with the fairing; and

leaving a second portion of the prosthetic limb exposed.

10. The method of claim 9 wherein the first portion of the prosthetic limb is a front surface of the prosthetic limb and the second portion of the prosthetic limb is a back surface of the prosthetic limb.

11. The method of claim 9 wherein the first portion of the prosthetic limb is a front surface of the prosthetic limb and the second portion of the prosthetic limb is a side surface of the prosthetic limb.

12. The method of claim 1 wherein the prosthetic limb includes a framework having cross section templates.

13. The method of claim 1 wherein the fairing includes a metal material.

14. The method of claim 1 further comprising:

performing one or more of the finishing processes on the fairing: plating, texturing, brushing, polishing or sand blasting.

15. The method of claim 1 further comprising:

applying a graphical design to the fairing.

16. The method of claim 1 wherein the fairing includes a recessed surface.

17. A method for creating a prosthetic limb comprising:

obtaining surface data for an intact limb;

creating a prosthetic limb design having an outer surface that corresponds to a mirror image of the surface data;

producing limb fabrication data and fairing fabrication data from the prosthetic limb design;

using the limb fabrication data, fusing a plurality of material particles together to form a plurality of layers that are fused to form the prosthetic limb; and

using the fairing fabrication data to fabricate multiple interchangeable fairings, an inner surface of the fairings fitting around the outer surface of the prosthetic limb that corresponds to a mirror image of the surface data.

18. The method of claim 17 wherein the prosthetic limb design includes a framework having a plurality of openings.

19. The method of claim 17 wherein the interchangeable fairings are discontinuous, the interchangeable fairings covering a first portion of the prosthetic limb and not covering a second portion of the prosthetic limb.

20. The method of claim 17 further comprising:

covering a first portion of the prosthetic limb with the interchangeable fairings; and

leaving a second portion of the prosthetic limb exposed.

21. The method of claim 20 wherein the first portion of the prosthetic limb is a front surface of the prosthetic limb and the second portion of the prosthetic limb is a back surface of the prosthetic limb.

22. The method of claim 20 wherein the first portion of the prosthetic limb is a front surface of the prosthetic limb and the second portion of the prosthetic limb is a side surface of the prosthetic limb.

23. The method of claim 17 wherein the prosthetic limb includes a framework having cross section templates.

24. The method of claim 17 wherein the fairings include recessed surfaces.
