2.3.1 AxonFlexion Adapter 9S500=*
Starting at the neutral position, the joint can be flexed by approx. 75° in 4 ratchet positions; exten
sion is approximately 45° with 3 ratchet positions.
Flexible Mode
Flexible mode simulates the natural movement characteristics of a relaxed wrist joint. This flexible
condition closely approximates the physical movement characteristics of the hand and wrist joint.
To select Flexible Mode, push the unlock lever to the stop (see Fig. 8) until it engages. The joint
can be moved without engaging at the ratchet positions. Pushing the lever again terminates Flex
ible Mode and the wrist unit engages at the next available position in Rigid Mode.
Rigid Mode
Various everyday conditions require an individually adjustable wrist unit of the gripping compon
ent in Rigid Mode. When the unlock lever is only pushed lightly and not to the stop (see Fig. 8),
the wrist unit can be moved to the desired position. When the unlock lever is released, the wrist
unit engages at the next available position.
2.3.2 AxonRotation Adapter 9S501
The gripping component can be manually rotated continuously through 360°. There are 24 ratchet
positions for this purpose, one at every 15°.
2.4 Elbow Joint
12K501 AxonArm Ergo (myoelectrically locked elbow joint)
Locking and unlocking is controlled myoelectrically by means of electrode signals or with a
switch.
12K500 AxonArm Hybrid (mechanically locked elbow joint)
Locking and unlocking is carried out mechanically, e.g. by means of body harnesses.
2.5 Axon-Bus Gripping Component (Michelangelo Hand 8E500)
The Michelangelo Hand is a myoelectrically controlled Axon-Bus gripping component in the mod
ular Axon-Bus prosthetic system. Complex gripping kinematics combined with an anatomical
appearance and low weight support everyday activities for maximum rehabilitation value. It fea
tures the following gripping options:
Neutral position
Natural, physiological appearance in the rest position.
Lateral power grip
The thumb moves laterally to the index finger; this laterally fixates medium-sized
objects when the thumb is in the half-open position.
Lateral pinch
The thumb moves laterally to the index finger; this laterally fixates flat objects
when the thumb is in the closed position.
