Fabricating The Outer Socket - Ottobock AeroLink 6A50 Instrucciones De Uso

5.2 Fabricating the outer socket

5.2.1 Preparing the inner socket
Required tools and materials:
>
Waste from vacuum cover (alternative: 617S3=3 Pedilin), 627B4 Poly­
ethylene Adhesive Tape, 623T3=* Perlon Stockinette, closed-cell foam
(e.g. 617S70=* Dynoform, 617S3=4 Pedilin or 617S26=H4 Lunasoft)
1) Position the inner socket on the plaster positive.
2) Trim a piece of vacuum cover left over from shortening the liner (approx.
4 cm longer than the vacuum cover on the liner).
3) Pull the piece of vacuum cover over the inner socket until it projects
approx. 2 cm over the proximal edge (see Fig. 6).
4) Pull 2 layers of Perlon stockinette over the model so that the pin receiver
is exposed (see Fig. 7, see Fig. 8).
5) Fabricate a cone of closed-cell foam material (thickness: 4 mm) accord­
ing to the proximal and distal circumference of the model.
6) Heat the cone in the oven and pull it over the model so that only the
distal third of the inner socket is exposed (see Fig. 9).
7) Evenly trim the cone, circular on the distal end, and sand the edge to
thin it.
5.2.2 Preparing the lamination disc
Required tools and materials:
>
6A55 Lamination Disc, Dummy Set for Lamination Disc, 633W8 Wax,
709Z2 Adjustable Pin Wrench
1) Unscrew the cap screws from the lamination disc and remove the inner
rings from the adapter ring (see Fig. 10).
2) Isolate the adapter ring with wax from the inside.
3) Isolate the dummies in the area of the thread and side walls with wax
(see Fig. 11).
4) Set the dummy with external thread on to the side of the adapter ring
marked 'distal' (see Fig. 12).
5) Set the dummy with internal thread on to the opposite side and screw on
the dummies (see Fig. 13).
