• Put two layers of 616G12 Carbon-Fibre Cloth on the distal area so as to provide an underlying
base with a projecting brim of 3 cm around the 4G70 Adapter, which will be mounted later in
the procedure. Pull on two layers of 623T3 Perlon Stockinette.
• The socket lamination is performed in two stages. In the first stage the socket is laminated up
to 2/3 of its length with 617H19 Orthocryl Lamination Resin. In the second stage the proximal
part of the socket is laminated with 617H17 Orthocryl Flexible Resin.
• Once the first casting has hardened, pull on 2 more layers of 623T3 Perlon Stockinette before
laminating the proximal part of the socket with 617H17 Orthocryl Flexible Resin.
Attention!
The lamination anchor acts as a flexion stop in the area of the EBS pivoting mount (Fig. 10).
To provide this stop function, and in order to avoid damage to the knee joint, an even con-
tact surface in the area of the EBS pivoting mount must be present after final lamination.
4.3.1.2 Applying the lamination anchor
• The correctly fitted lamination anchor must be prepared before it is glued to the socket.
• To do this, fill the coupling opening with 636K8 Plastaband. Clamp the socket and joint into
the alignment apparatus. Remove any soft, flexible or porous materials from underneath the
lamination anchor's supporting surface.
Attention!
Mix the putty exclusively from 617H21 Orthocryl Sealing Resin and 639A1 Talcum Pow-
der. Then glue on the lamination anchor.
• Secure with 627B2 Adhesive Tape for trial fitting. Test the stop function (see Section 4.3.1.1).
If necessary, form the required contact surface with putty. It is also possible to glue a stop
bumper of Pedilin onto the outer laminate.
4.3.1.3 Socket completion
Once the trial fitting has been completed, attach the lamination anchor to the socket with truss
head screws and round nuts with two holes, and then laminate.
Proceed with further reinforcement as follows:
• Two layers of 616G12 Carbon Fibre Cloth must be sandwiched between two layers of 623T3
Perlon Stockinette. To do this, pull one layer of 623T3 Perlon Stockinette over the whole socket
and tie it on the top circularly, apply the two layers of 616G12 Carbon Fibre Cloth over the
arms of the 4G70 Adapter, and then reflect the remaining half of the 623T3 Perlon Stockinette
over the carbon fibre layers.
• Now reinforce once again with 616G13 Fibreglass Stockinette (as described in Section 4.3.1.1).
• Finally, pull on two layers of 623T3 Perlon Stockinette. Proceed with lamination as performed
in the first stage of lamination.
Attention!
Deviating from the processing instructions and the recommended materials for the lami-
nation of the anchor can lead to a loosening or breaking of the adapter.
Attention!
Upon completion of the assembly tighten the adjustment screws with 710D1 Torque
Wrench. Torque: 15 Nm (11 ft.lbf/133 in.lbf). Once you have attained the final setting
for the prosthesis, use 636K13 Loctite to secure the set screws.
