Fabricating The Prosthetic Socket - Ottobock 6A43 Instrucciones De Uso

5.1 Fabricating the Prosthetic Socket

5.1.1 Preparing for Socket Fabrication
Required tools and materials:
>
6A43 Lamination Adapter, 501T28=M6X8 Cap Screws, Vacuum forming
dummy, 503S3 Screw, 633W8 Wax, 636K8=* Plastaband
1) Isolate the cap screws (thread and head from the outside) with wax.
2) Screw the cap screws into the lamination adapter (see Fig. 2).
3) Fill the heads of the cap screws with Plastaband (see Fig. 3).
4) Position the lamination adapter on the plaster positive along the longitud­
inal axis of the residual limb.
5) Place the vacuum forming dummy into the round opening of the lamina­
tion adapter and secure the two parts to the plaster positive with the flat
head screw (see Fig. 4).
6) Isolate the head of the flat head screw with Plastaband.
7) If there is an undercut between the lamination adapter and plaster
positive: Fill the undercut with wet plaster.
5.1.2 Fabricating a Check Socket
Required tools and materials:
>
755T4=360 Outer Ring, 755X104=360 Vacuum Tube (with vacuum seal­
ing ring), 755E9 Vacuum Pump, 756D2, 756B12=* or 756B20=* Oscil­
lating Saw, 616T52=* ThermoLyn rigid or 616T83=* ThermoLyn clear,
string
1) Prepare for fabrication of the prosthetic socket (Preparing for Socket
Fabrication).
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 Page 20).
5.1.3 Laminating a 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 Lamination
Resin 80:20 PRO, string
1) Prepare for fabrication of the prosthetic socket (Preparing for Socket
Fabrication).
2) Soak the shorter PVA bag and pull it over the plaster positive.
