Checking The System Joint's Free Movement; Checking The Lock Function; Securing The Screws - FIOR & GENTZ NEURO LOCK H2O Notice D'utilisation

3 Slide the joint's lower part from below into the joint's upper part
(fig. 10). Make sure that the sliding washers are centred correctly
(fig. 11). To do so, use the sliding washer centring pin.
4 Grease the axle bore of the joint axis and the friction surfaces of the
bearing nut of the joint axis with orthosis joint grease.
5 Put the bearing nut of the joint axis into the opening of the joint's
upper part. Make sure that the cut-outs of the bearing nut and the
joint's upper part match (fig. 12). The bearing nut must be fully
inserted in the opening.
6 Place the cover disc of the joint axis onto the front of the joint's
upper part. The cover disc must be fully inserted in the opening. Make
sure that the cut-outs of the cover disc and the joint's upper part
match.
7 Screw in the countersunk flat head screw (axle screw, S2; fig. 13).

Checking the System Joint's Free Movement

Check if the system joint moves freely. If the system joint runs with
lateral play, mount the next thicker sliding washer. If it does not move freely (it is
jammed), mount the next thinner sliding washer.
8.5

Checking the Lock Function

1 Unlock the system joint again and have the locking pawl snap in maximum
extension.
2 Check the correct position of the locking pawl. It must not be mounted too high
(fig. 14).
The locking pawl should be free of play in the lowest position. If you note play in
the system joint in ap direction, you can correct it by using the precisely adjustable
extension stop. To do so, screw in the cheese head screw of the extension stop until
the locking pawl falls into the joint's lower part as shown (fig. 15) and there is no
play remaining.

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 joint's upper part (fig. 13) with the torque corresponding to the system width
and LOCTITE® 243 medium strength.
2 Let the adhesive harden (final strength after approx. 24 hours).
