Installation Instructions - Otto Bock E-MAG Active 17B203 Instructions For Use Manual

INFORMATION
Maintenance and repairs to the joint bearing are permitted. Repairs to the locking mechanism may only be per­
formed by an Ottobock Service Centre.

3 Installation instructions

This section describes the steps for installing the E-MAG knee joint system in an orthosis. It also includes instruc­
tions for fabricating a casing which, attached to the transfemoral socket, protects the electronics, cables and bat­
tery housing from outside influences. The 17B203=* knee joint system was supplied to you as a complete package.
All required functional components are included, except for the medial support and lamination joint bars. The sys­
tem is operational after installation and upon fully charging the battery.
NOTICE
Risk of damage to electronic components
Use the dummies included in the scope of delivery for all process steps until completion of the orthosis. Only
replace the dummies with the electronic components directly before trial fitting or upon completion of fabrication.
Only use the M5 x 10 screws included in the scope of delivery. The magnetic control on the upper section of the
orthosis is equipped with threaded blind holes to attach the lamination anchors. Using screws that are too long
may damage the control unit.
INFORMATION
We recommend the initial fabrication of a trial orthosis. This can be used for casting once the fit and functionality
are satisfactory. The risk of alignment problems is minimised by this approach. Alignment problems can result in
failure of the E-MAG knee joint system to extend fully, so that it cannot be opened and / or closed.
3.1 Installation of the E-MAG knee joint system
INFORMATION
The joint can be installed using different types of orthotic techniques. We recommend the lamination resin or
prepreg technique.
First model the plaster positive. Position the dummy (A) for the knee joint (B) (see fig. 7) directly onto the Nietert's
compromise pivot point with the help of the 743R6 joint alignment fixture (see fig. 8). Align the medial support
dummy parallel to the E-MAG knee joint dummy.

The dummy is constructed such that the E-MAG knee joint has a 6 mm posterior placement. Now select the posi­
tion of the electronic components. The battery and electronics are to be placed only on the thigh. This results in
favourable weight distribution. At the same time, the cable between the knee joint and electronics is not subjected
to unnecessary strain.
Select soft tissue regions that adapt easily to the form of the dummies. The dummies must lie flat on the selected
regions when forming the plaster positive. Otherwise, they may become curved through heat build-up during lamin­
ation. This may prevent the original components from subsequently fitting into the recess (see fig. 9). The manufac­
turer recommends positioning the electronics and battery unit laterally on the orthosis. This prevents collision with
the contralateral side, especially for bilateral fittings.
