Adjusting The Torsion Moment On The 2R21 Axon Tube Adapter; Bench Alignment In Alignment Apparatus; Static Alignment Optimisation - Otto Bock Genium 3B1-3 Instructions For Use Manual

Preparing the product for use
CAUTION
Improper assembly of the screw connections
Falling due to breakage or loosening of the screw connections.
► Clean the threads before every installation.
► Apply the specified tightening torque values for installation (see the section "Technical data" see Page 49).
► Observe the instructions for securing the screw connections and the use of the correct length.
1) Install the prosthetic foot on the tube adapter and tighten the set screws on the tube adapterto a torque of
15 Nm.
INFORMATION: The printed scale on the tube adapter must face forward.
2) Connect the cable of the tube adapter to the cable of the knee joint.
3) Push the protruding cable loop back into the tube adapter. If the tube adapter has been shortened to the min­
imum length, the plug must be inserted in the cavity. The cable loop must then be stored carefully.
4) Insert the tube adapter about 60 mm into the knee joint (for the exact value, consult the configuration assistant
in the adjustment software).
INFORMATION: Corrections in the insertion depth between 40 mm and 70 mm are permissible (slide
in 10 mm and pull out 20 mm).
5) Turn the foot outwards slightly and slightly tighten the two distal tube clamp screws (approx. 4 Nm).
INFORMATION: After trial fitting, all screws have to be tightened alternately in several steps, increas­
ing the tightening torque slowly until the prescribed tightening torque is reached (section "Technical
data", see Page 49).

7.1.4 Adjusting the torsion moment on the 2R21 AXON tube adapter

CAUTION
Incorrect setting of the torsion moment in the torsion unit
Falling due to unexpected behaviour of the product.
► The marking on the Allen head screw may not be turned as far as the red area or beyond the red area.
The torsion moment can be adjusted with the Allen head screw in the centre of the adapter.
Increasing the torsion moment:
► Turn the mark in the centre of the torsion unit clockwise.
Decreasing the torsion moment:
► Turn the mark in the centre of the torsion unit counterclockwise.
INFORMATION
If the patient notices a sudden change in the torsion moment, check whether the mark of the Allen head screw is
still within the setting range. Correct the setting if this is not the case.

7.1.5 Bench alignment in alignment apparatus

With correct bench alignment, e.g. in the PROS.A. assembly alignment apparatus (743A200), the benefits of the
product are realised to best advantage. If the L.A.S.A.R. assembly alignment apparatus (743L200) is available, it
can be used as well.
Alignment can also be carried out using LaserLine/plumb line.
A calibrated alignment recommendation for prosthesis bench alignment is provided in the adjustment software for
the individual conditions of the prosthesis and patient. Therefore, consult the adjustment software for the alignment
data.
The following points must be observed during alignment:
Static alignment in the alignment apparatus must always be carried out without shoes, otherwise a correct
•
adjustment will not be possible.
• Static alignment with the LaserLine/plumb line must be carried out with shoes, otherwise a correct adjust­
ment will not be possible.
• Ensure the knee joint is in full extension during bench alignment. To do so, briefly push the socket once into the
fully extended position.

7.1.6 Static alignment optimisation

The adjustment software specifies concrete reference values based on measurement data to help optimise the
alignment.
A precondition is that the alignment recommendations were followed during bench alignment of the prosthesis.
