5.1.2 Fabricating a Check Socket
>Required tools and materials:
755T4=360 Outer Ring, 755X104=360 Vacuum Tube (with vacu
um sealing ring), 755E9 Vacuum Pump, 756D2, 756B12=* or
756B20=* Oscillating Saw, 616T52=* ThermoLyn rigid or
616T83=* ThermoLyn clear, string
1) Prepare for fabrication of the prosthetic socket (see page13).
2) Position two pieces of string crosswise on the lamination adapter
(see fig.5). The pieces of string form air channels that make it
easier to mould the vacuum forming material to the contours.
3) Complete the vacuum forming process with ThermoLyn.
4) Finish the prosthetic socket (see page15).
5.1.3 Laminating the transtibial socket
>Required tools and materials:
99B81=70X19X5 and 99B81=100X19X5 PVA Bag, 623T3=8 or
623T3=10 Perlon Stockinette, 81A1=8 or 81A1=10 Tube Sock,
616B1=25x* Carbon Fibre Cloth Strap, 616G2 Carbon UD Hose,
616G15 Carbon Fibre Woven Hose, 617H119 Orthocryl Lamina
tion Resin 80:20 PRO, string
1) Prepare for fabrication of the prosthetic socket (see page13).
2) Soak the shorter PVA bag and pull it over the plaster positive.
3) Pull a tube sock over the plaster positive.
4) Place a layer of carbon fibre cloth strap circularly around the MPT
(middle patellar tendon) point (see fig.6).
5) Position a layer of carbon fibre cloth strap medially and laterally
from the shuttle lock up to the condyles (see fig.7).
6) Place a layer of carbon fibre cloth strap anteriorly and posteriorly
from the shuttle lock to the circular carbon fibre cloth strap (see
fig.8).
7) Pull a tube sock over the plaster positive.
8) Loop a piece of string around the lamination adapter in the groove
and tie tightly (##03119).
9) Cut a piece of carbon UD hose (1.5 times the length of the plaster
positive).
14
10) Pull the carbon UD hose over the plaster positive up to the socket
edge. Tie the upper section of the carbon UD hose and fold the
remaining length over the plaster positive.
11) Loop a piece of string around the lamination adapter in the groove
and tie tightly (see fig.9).
12) Pull a tube sock over the plaster positive.
13) Cut a piece of carbon fibre woven hose (1.3 times the length of
the plaster positive).
14) Pull the carbon fibre woven hose over the plaster positive to the
socket edge. Tie the upper section of the carbon fibre woven
hose and fold the remaining length over the plaster positive (see
fig.10).
15) Cut a piece of Perlon stockinette (twice the length of the plaster
positive).
16) Pull the Perlon stockinette over the plaster positive up to the sock
et edge. Tie the upper section of the Perlon stockinette and fold
the remaining length over the plaster positive.
17) Soak the longer PVA bag and pull it over the plaster positive.
18) Perform the casting process with Orthocryl.
19) Finish the prosthetic socket (see page15).
5.1.4 Laminating a transfemoral socket
>Required tools and materials:
99B81=100X26X5 and 99B81=130X26X5 PVA Bag, 623T3=12 or
623T3=15 Perlon Stockinette, 81A1=12 or 81A1=15 Tube Sock,
616B1=50x* Carbon Fibre Cloth Strap, 616G2 Carbon UD Hose,
616G15 Carbon Fibre Woven Hose, 617H119 Orthocryl Lamina
tion Resin 80:20 PRO, string
1) Prepare for fabrication of the prosthetic socket (see page13).
2) Soak the shorter PVA bag and pull it over the plaster positive.
3) Pull a layer of Perlon stockinette over the plaster positive.
4) Place a layer of carbon fibre cloth strap circularly 3cm below the
perineum.
