Abstract

A fairing can be attached to a prosthetic limb or over a brace to alter the appearance of the prosthetic limb or brace. The outer surface of the prosthetic limb can be a mirror image of an intact limb and the outer surface of the brace can have an outer surface that corresponds to an injured limb. Because the fairing fits closely around the prosthetic limb or brace, the interior surface of the fairing has a surface that corresponds to a mirror image of an intact limb or an outer surface of an injured limb.

First claim

What is claimed is:

1. A method for creating a fairing for a prosthetic limb comprising:
providing a computing device having a display and a graphical user interface that displays a plurality of colors and a plurality of graphical patterns for the fairing;
photographing an intact limb of a patient's body with a digital camera to produce a plurality of 2D digital images;
transmitting photographs of the limb to the computer;
obtaining surface measurements of the intact limb of the patient's body;
inputting to the graphical user interface a selected color of the fairing selected from the plurality of colors and a selected graphical pattern selected from the plurality of graphical patterns for the fairing;
creating a fairing design from the selected color, the selected graphical pattern and the measurements of the limb; and
fabricating the fairing from the fairing design wherein the fairing has an outer surface that corresponds to the measurements of the intact limb, the fairing is the selected color and the selected graphical pattern, and the fairing includes fastener components for holding the fairing to the prosthetic limb.

2. The method of claim 1 wherein the fabricating of the fairing includes applying a metal layer to an outer surface of the fairing that alters the appearance of the fairing.

3. The method of claim 1 wherein the fabricating of the fairing includes a plurality of selected colors.

4. The method of claim 1 wherein the fabricating of the fairing includes applying a colored dye or paint in an outer surface of the fairing.

5. The method of claim 1 wherein the fabricating of the fairing includes applying a metal layer on an outer surface of the fairing that has a brushed finish, a polished finish or a sand blasted finish.

6. The method of claim 1 wherein the fabricating of the fairing includes applying a leather material on an outer surface of the fairing.

7. The method of claim 1 wherein the selected graphical pattern of the fairing includes a plurality of openings that alter the appearance of the fairing.

8. The method of claim 7 wherein the selected graphical pattern includes a plurality of colors, materials and holes.

9. 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.

10. The method of claim 9 wherein the first portion of the fairing is attached to an upper surface of the prosthetic limb and the second portion of the fairing is attached to a lower surface of the prosthetic limb.

11. The method of claim 9 wherein the first portion of the fairing is attached to a front surface of the prosthetic limb and the second portion of the fairing is attached to a rear surface of the prosthetic limb.

12. The method of claim 1 wherein the fabrication of the fairing includes applying a plated section made of: chrome, zinc, gold, silver, or nickel.

13. The method of claim 1 wherein the fabrication of the fairing includes applying a metal material that alters the appearance of the fairing.

14. The method of claim 1 wherein the fairing design includes one or more of the following finishing processes: plating, texturing, brushing, polishing or sand blasting.

15. The method of claim 1 wherein the fairing includes a plurality of different materials.

16. The method of claim 1 wherein the prosthetic limb is a prosthetic leg.

17. A method for creating multiple interchangeable fairings comprising:
providing a computer having a computer having a display and a graphical user interface that displays a plurality of colors and a plurality of graphical patterns for the fairing;
photographing an intact limb of a patient's body with a digital camera to produce a plurality of 2D digital images;
transmitting photographs of the limb to the computer;
obtaining surface measurements of the limb of the patient's body;
inputting to the graphical user interface a selected color for each of the multiple interchangeable fairings selected from the plurality of colors and a selected graphical pattern selected from the plurality of graphical patterns for each of the interchangeable fairings;
creating fairing design data having an outer surface data that corresponds to the surface data for the intact limb of the body using a computer, wherein the computer includes a graphical user interface that allows colors of the interchangeable fairings to be selected from a plurality of colors and viewed prior to fabrication; and
fabricating the multiple interchangeable fairing from the fairing design wherein the interchangeable fairings have outer surfaces that correspond to the measurements of the limb, each of the multiple interchangeable fairings includes one of the selected colors and one of the selected graphical patterns and the fairings include fastener components for holding the fairing to the prosthetic limb.

18. The method of claim 17 wherein the interchangeable fairing designs each include a plurality of openings that alter the appearances of the interchangeable fairings.

19. The method of claim 17 wherein a plurality of openings form a graphical pattern that alter the appearances of the interchangeable fairings.

20. The method of claim 17 wherein the interchangeable fairing designs cover a first portion of a prosthetic limb and not covering a second portion of the prosthetic limb.
