• Mark the position of the lamination ring on the shaped foam part (Fig. 6).
After determination of the prosthesis length remove the elbow set-up from
the shaped foam part.
• Only use Orthocryl sealing resin for attaching the lamination ring, hand
adapter etc.; pour from inside into the grooves avoiding the formation
of bubbles.
4.2.1 12K5=* / 12K20=*
Disassembling the lamination ring
• To remove the 13G8=67 Lamination Ring (Fig. 1, item B) from the elbow
set-up, you first have to separate the 13Z2=4 Lock Ring (Fig. 7, item A)
from the 13G11 / 13G39 Set Screw. After loosening the set screw (Fig. 3)
you can remove the lock ring. Then remove the lamination ring with at-
tached parts from the elbow ball (Fig. 8).
Assembly
• Isolate the inner contours of the lamination ring with silicone grease
and transfer it to the shaped foam part with light putty. This will ensure
exact positioning of the lamination ring (Fig. 9). Pull a PVA bag over the
shaped foam part and inner contours of the lamination ring and tie off
distally. Degrease the lamination ring and attach it over the PVA bag
to the shaped foam part (Fig. 10). Laminate the outer socket over the
shaped foam part and lamination ring.
• Once the laminate has cured, lay bare the lamination ring by grinding
(Fig. 11) and remove the shaped foam part.
• Screw the elbow ball to the lamination ring.
• Once again, temporarily affix the wrist unit and terminal device to the
elbow set-up to verify the length of the prosthesis. Shorten the forearm
socket a bit more, if necessary. It is important, however, that the diameter
for the wrist unit remains unchanged in the forearm socket.
4.2.2 12K19=40
Disassembling the lamination ring (12K19=40)
• After loosening the 506G1=M8x15 Adjustment Screws (Fig. 2, item A),
the lamination ring with 13G9=47 Upper Arm Rotation Piece (Fig. 2,
item B) can be separated from the elbow ball.
