Mounting the Spring Unit NEURO VARIO-SWING

For system knee joints without a spring unit, skip these steps
and continue the assembly at paragraph 8.7.
1 Place the stop damper (3) into the guide ring (2).
2 Insert the extension stop (1) and guide ring (2) into the
spring duct (fig. 18).
3 Stick the screw unit (5) onto the spring unit (4).
4 Screw in the sub-assembly into the spring duct (fig. 18).
5 Screw in the sub-assembly until the required alignment
of the orthosis is achieved. Depending on the setting of
the system ankle joint, a joint angle of approximately 5°
corresponds to a physiological joint angle.
6 Make sure that the nose of the joint's lower part is aligned
with the marking in the centre to obtain a physiological
joint angle of 5° (fig. 19).
When mounting the spring unit, mind the cor-
rect alignment of the entire orthosis. In order for
a changed extension stop angle not to affect the
orthosis alignment negatively, also correct the system
ankle joint, if necessary.

Securing the Screws

The screws are secured after the orthosis has been produced and tried on and
before it is handed over to the patient.
1 Secure the screws for the cover plate (fig. 15) with the torque corresponding to
the system width and LOCTITE® 243 medium strength.
2 Let the adhesive harden (final strength after approx. 24 hours).
Screws for Cover Plate
S1 (screw 1, axle screw)
S2 (screw 2)
The screws of the cover plate are not secured with the necessary torque at delivery.
You can also find information on the torque in the openings of the cover plate.
