Otto Bock 8E44 6 Instructions For Use Manual page 20

Apply and form 617H12 Pedilen rigid foam 200 to inner socket (Fig. 11).
3.
Working with the patient, establish the desired position of the hand using the Pedilen rigid
4.
foam. The position and rotation of the hand should have a natural appearance. Only minor
adjustments can be made once the final position has been established.
Mark the perimeter of the lamination plate on the Pedilen rigid foam.
5.
With the help of the included special ring key, separate the hand from the lamination plate.
6.
Reduce the marked perimeter by 3 mm to provide enough clearance for the wire loops to fit
7.
over the Pedilen rigid foam (Fig. 12). Then shape the distal end of Pedilen rigid foam to this
reduced perimeter. Make sure the RA-radius (thumb side) and UL-ulna markings are placed
correctly on the model.
The lamination plate must sit level on the foam (Fig. 13a and 13b)!
Pull the PVA bag with distally sealed-seam over the model.
8.
Cut a double-length of Perlon stockinette, sew it in the middle, and reflect it back over the
9.
rigid foam, making sure there are no wrinkles in the fabric (Fig. 14).
10. Screw the cable lamination cover onto the lamination plate. The opening in the middle of the
plate comes with a piece of tape covering it (Fig. 15a, Pos. 1). Evenly snap the lamination
cover into position (15b).
11. Using pigmented 617H21 Orthocryl Sealing Resin, glue the lamination plate under a load of
2 kg (Fig. 16) to the rigid foam over which 2 layers of perlon stockinettes have been pulled.
12. Cut off a double-length of Perlon stockinette, pull half over the model and tie-off beneath the
lamination ring with thread (Fig. 17a). Reflect remaining half of the stockinette as shown in
Fig. 17b.
13. If heavier loading of the prosthesis is expected, add additional layers of perlon stockinette
or reinforce with carbon.
14. Carefully pull on the moistened PVA bag and begin the lamination process (617H19
Orthocryl Lamination Resin).
15. Once the resin has set, remove the lamination cover from the lamination plate (Fig. 18), and
remove the tape. Separate the inner socket from the outer shell.
16. Remove the cable lamination cover. In order to maintain the cable relief, use a hot needle to
completely burn out any resin in the opening (Fig. 19).
17. Sand the distal end of the shell smooth (Fig. 20) in order to avoid any damage to the inner shell.
18. Thread the 4-pole hand cable through the lamination plate (Fig. 21) and evenly press in the
cable insulation (see cable installation, Fig. 7-Fig. 9).
19. Attach hand to lamination plate. To make adjustments, tighten the nut with the included
special ring key.
20. Plug the 4-pole hand cable into the connection block. Secure the nuts with 636W60
Loctite 243.
21. Pull the inner shell over the hand and lamination plate and tie-off in the groove with the
included special thread. Seal the slit between the System Inner Hand and the prosthetic
socket with 633F11 Silicone Grease.
22. Pull on the prosthetic glove. If it is difficult to pull on, heat the glove and stretch it out.
