Abrégé anglais


A prosthetic limb and process to digitally construct a prosthetic limb which
includes first, digitally producing a modified mold of a residual limb via 3d
scanners and
software known to the industry; constructing a test socket from the digitally
modified
mold and be equipped with an alignable system; for example, a pylon, along
with the
desired prosthetic foot; accurately scanning the test socket, preferably with
a 3D scanner,
along with finalized alignment that has been recorded and adjusted by a
certified
practitioner to provide a 3-D Image of the finalized prosthetic alignment;
transferring the
finalized digital alignment of the test socket to the finalized digitally
modified mold; once
the modified model has received the transferred alignment, fabricating the
type of
hookup in the socket; i.e., plug fit, four hole, support drop lock, or any
other type of
industry standard connection or accommodation via basic 3D software; and once
the
desired prosthetic attachment is finalized, the next step is to send the
finished file to a 3-
D printer to produce the definitive prosthetic device. The 3-D printed socket
would then
be placed in a vibratory finishing system to smooth out the interior and
exterior surfaces
of the printed socket; and the walls of the 3-D printed socket would be sealed
by
applying a mixture of epoxy sealant, for example, TC-1614, to the inside and
outside
walls of the socket, and placing the socket into an oven for a sufficient
amount of time to
seal the walls of the socket. Preferably, the prosthesis would be printed out
of Nylon 12
material or of a strong plastic, such as ULTEM®, or carbon fiber, or other
material of
equivalent or greater strength that may be known or developed in the future.

CLAIMS
1. A process to digitally construct a prosthetic limb, comprising the
following steps:
a) digitally producing a modified mold of a residual limb via 3d scanners
and
software;
b) constructing a test socket from the digitally modified mold;
c) equipping the test socket with an alignable system, including a pylon,
along with the desired prosthetic foot;
d) accurately scanning the test socket, preferably with a 3D scanner, along

with finalized alignment that has been recorded and adjusted to provide a 3-D
Image of
the finalized prosthetic alignment;
e) transferring the finalized digital alignment of the test socket to the
finalized digitally modified mold; and
placing the 3-D printed socket in a vibratory finishing system to smooth
out the interior and exterior surfaces of the printed socket.
2. The process in claim 1, wherein the test socket is scanned with a 3D
scanner.
3. The process in claim 1, wherein the test socket constructed of Nylon 12
material, or other suitable materials, including, but not limited to
ULTEM®, carbon
fiber, or other material of equal or greater strength that may be known or
developed in the
future.
4. The process in claim 1, further comprising the step, once the modified
mold has received the transferred alignment, of fabricating the type of hookup
in the
socket; such as a plug fit, a four hole fit, support drop lock, or any other
type of industry
standard connection or accommodation via basic 3D software.
5. The process in claim 4, once the desired prosthetic attachment is
finalized,
sending the finished file to a 3-D printer to produce the definitive
prosthetic device.
6. The process in claim 4, wherein a preferable printer is sold under the
trademark of Fortus® which would be utilized in this process.
7. The process in claim 1, further comprising the step of sealing the 3-D
printed socket by applying a high solids content epoxy penetrating sealing and
coating
¨13¨


resin, or some other equivalent epoxy sealing product, to the inside and
outside walls of
the socket, and placing the socket into an oven for a sufficient amount of
time to seal the
walls of the socket.
8. A method of constructing a prosthesis of Nylon 12 material,
comprising
the steps of:
a) retrieving a file from a computer;
b) manipulating that file;
c) adjusting each "Z" line in the file to insure the strongest build of the

socket with proper trim lines;
d) sending the file to a 3D printer; and
e) printing out a prosthesis constructed of a material sufficiently strong
to
function as a prosthetic limb and which allows one to build the prosthesis
with prosthetic
techniques for attachments.;
f) placing the 3-D printed socket in a vibratory finishing system to
smooth
out the interior and exterior surfaces of the printed socket; and
sealing the 3-D printed socket by applying an epoxy sealing material to
the inside and outside walls of the socket, and placing the socket into an
oven for a
sufficient amount of time to seal the walls of the socket.
9. The method in claim 8, wherein the attachments would be selected
from a
group comprising:
a) a four hole hook up with vacuum;
b) a four hole hook up that will support a drop lock;
c) a fitting of cylindrical adapter; and
d) custom attachments for certain feet/attachments.
10. The method in claim 8, wherein the material to construct the socket
may
be selected from suitable materials, including, but not limited to ULTEM®,
carbon fiber,
or other material of equal or greater strength that may be known or developed
in the
future, constructing a prosthesis.
11. The process in claim 8, wherein the vibratory finishing system
comprises a
batch vibratory unit, such as Model VB-2034 End Discharge Vibratory Finishing
System
of the type manufactured by ALMCO.
¨14¨


12. The method in claim 8, where in the epoxy sealing material comprises
a
high solids content epoxy penetrating sealing and coating resin system,
manufactured by
BJB Enterprises, or some other equivalent epoxy sealing product.
13. A method of constructing a prosthesis, comprising the steps of:
a) retrieving a file from a computer,
b) manipulating that file,
c) adjusting each "Z" line in the file to insure the strongest build of the
socket with proper trim lines;
d) sending the file to a 3D printer;
e) printing out a prosthesis constructed of a material, preferably Nylon
12,
but other suitable materials may include ULTEM®, carbon fiber, or other
material of
equal or greater strength that may be known or developed in the futureõ so
that the
prosthesis is able to function as a prosthetic limb; and
f) sealing the 3-D printed socket by applying a epoxy sealing material,
to the
inside and outside walls of the socket, and placing the socket into an oven
for a sufficient
amount of time to seal the walls of the socket.
14. The method in claim 13, further comprising the step placing the 3-D
printed socket in a vibratory finishing system to smooth out the interior and
exterior
surfaces of the printed socket prior to sealing the walls of the socket.
15. The method in claim 13, where in the epoxy sealing material
comprises a
high solids content epoxy penetrating sealing and coating resin system,
manufactured by
BJB Enterprises, or some other equivalent epoxy sealing product.
