Gluing The Lamination Plate; Completing The Check Socket; Fabricating The Definitive Socket - Ottobock 4R180 Harmony P4 Instrucciones De Uso

5.2 Gluing the lamination plate

Required materials: 627B4 polyethylene adhesive tape, suitable adhesive (such as 636K49
>
SuperGlue, sealing resin-talcum mixture, Fabtech +PLUSeries 60-second adhesive), 699G30
synthetic support bandage
1) Screw the lamination plate with the threaded ring onto the vacuum pump.
2) Cover the hole in the centre of the lamination plate with polyethylene adhesive tape (see
fig. 2).
3) Install the distal prosthetic components as described in the respective instructions for use.
4) Perform the bench alignment and determine the required structural height and alignment of
the prosthetic components relative to the prosthetic socket.
5) INFORMATION: The glued joint between the lamination plate and prosthetic socket
must be air tight.
Glue the lamination plate to the prosthetic socket using suitable adhesive (see fig. 3). In doing
so, ensure that air inclusions are avoided.
6) Allow the adhesive to cure fully.
7) Once the adhesive has hardened, unscrew the vacuum pump from the lamination plate.
8) Either complete the check socket (see Page 18) or fabricate the definitive socket (see
Page 18).

5.3 Completing the check socket

Required materials: 627B4 polyethylene adhesive tape, 699G30 synthetic support bandage
>
1) Secure the connection between the prosthetic socket and lamination plate with synthetic sup­
port bandage (see fig. 4). In doing so, wrap the support bandage firmly around the prosthetic
socket up to the groove in the lamination plate.
2) INFORMATION: In order for the sealing sleeve to seal, it has to overlap an air-tight
surface by about 5 cm.
If required, wrap the support bandage which is permeable to air with polyethylene adhesive
tape to create an air-tight surface.
3) Drill a hole (Ø 4 mm) through the middle of the lamination plate into the plaster model (see
fig. 5).
4) Remove the prosthetic socket from the plaster model.
5) Deburr the hole on the inside of the socket.
6) Clean the prosthetic socket, lamination plate and bore hole.
7) Install the vacuum pump (see Page 19).
INFORMATION: Seal the hole in the prosthetic socket with a piece of adhesive tape if
the prosthetic socket requires modification after pump installation. This prevents
debris from entering the vacuum pump.
8) Optional: Install the 2R117-0 socket connector as described in the applicable instructions for
use. This allows the vacuum level to be determined.

5.4 Fabricating the definitive socket

5.4.1 Laminating the transtibial socket
Required tools and materials:
>
99B81* PVA bag, 623T3=8 or 623T3=10 Perlon stockinette, 81A1=8 or 81A1=10 nylon tube
sock, 616G15 carbon fibre woven hose, Nylglass stockinette 623T9*, 617H119 Orthocryl lam­
ination resin 80:20 PRO, string
Requirement: The thermoplastic socket has been fabricated and the lamination plate has
>
been glued on.
1) Apply a thin layer of Vaseline to the inside of the lamination plate (see fig. 6).
2) Insert the lamination dummy into the lamination plate (see fig. 7).
3) Seal the distal surface of the lamination plate with polyethylene adhesive tape (see fig. 8).
4) Pull a nylon stockinette over the plaster model.
