5.1 Fabricating the Prosthetic Socket
First lamination process
>
Materials required:
99B81 PVA bag, 616G6 Dacron® felt, 623T3 Per­
lon stockinette, 616G12 carbon fibre cloth, 617H119 Orthocryl lamina­
tion resin 80:20 PRO
1) Pull a soaked PVA bag over the prosthetic socket.
2) Place a layer of Dacron® felt over the entire prosthetic socket.
3) Place a layer of Dacron® felt around the proximal socket edge.
4) Pull 2 layers of Perlon stockinette over the prosthetic socket.
5) Place 3 layers of carbon fibre cloth (e.g. 15 cm x 15 cm) on the distal
end of the prosthetic socket, offsetting the fibre alignment.
6) Pull 2 layers of Perlon stockinette over the prosthetic socket.
7) Pull a soaked PVA bag over the prosthetic socket.
8) Complete the lamination process with lamination resin.
9) Once the lamination resin has cured, remove the PVA bag.
Foaming and fastening the socket attachment block
>
Materials required:
617H32 Pedilen rigid foam 300, 617H21 Orthocryl
sealing resin
1) Sand down the surplus lamination resin on the distal end of the prosthet­
ic socket.
2) Foam the distal end of the prosthetic socket using rigid foam.
3) Trim the rigid foam as much as possible and sand it smooth in the
desired position.
4) Fasten the socket attachment block to the rigid foam with sealing resin.
5) Mill a transition between the socket attachment block and the rigid foam.
Do not sand the shape or size of the adapter connection surface, which
is determined by the socket attachment block.
6) Insert the lamination dummy in the threaded holes of the socket attach­
ment block (see fig. 2).
7) Apply coloured sealing resin to the outside of the prosthetic socket and
to the lamination dummy (see fig. 3).
