2 Product description

2.1 Construction and Function

12K500 AxonArm Hybrid
The 12K500 AxonArm Hybrid is a mechanically locked elbow joint. Locking and unlocking is carried out mechanic­
ally, e.g. by means of body harnesses.
12K501 AxonArm Ergo
The 12K501 AxonArm Ergo is a myoelectrically locked elbow joint. Locking and unlocking is controlled myoelectric­
ally by means of electrode signals or with a switch.
The AxonArm Hybrid or the AxonArm Ergo helps the patient perform everyday tasks in combination with other pros­
thetic components of the Axon-Bus prosthesis solution, such as the 8E500 Michelangelo hand.
A Li-ion battery integrated into the product provides the required energy.
If the elbow joint is off or the battery is depleted, the elbow joint can still be locked and unlocked in any position,
even when loaded, by means of the pull cable.

2.2 Definition of terms

AFB (Automatic Forearm Balance)
AFB is a flexion assist in the form of a mechanical gear mechanism in the forearm of the elbow joint. The Automatic
Forearm Balance provides for harmonious movement control, free swing and reduction of energy consumption. It
stores the energy that is released when the arm is extended and uses this to assist with flexion. The degree of flex­
ion assistance can be adjusted to the individual weight of the prosthetic forearm and to different clothing by means
of a dial.
The free swing of the forearm corresponds to the natural movement behaviour of the upper limb while walking.
After extension of the forearm, the vario-gear automatically decouples the forearm from the drive unit so it can
swing freely. The AFB slightly dampens the free swing, thereby making a close approximation of the forearm's
physiological movement behaviour possible.
The product does not consume electrical energy during the free swing. A short muscle signal to flex the product
ends the free swing.
Easy Plug
The Easy Plug is a through-connection for myoelectrically controlled prostheses that is integrated in the elbow
joint.
The connecting cables of the electrodes, switches and batteries are connected to the Easy Plug. Its interior cable
routing minimises the risk of cable breaks.
With the AxonArm, only the 13E500 AxonMaster is connected in the area of the elbow ball. All other plug connec­
tions have no function and are therefore closed with cover caps.
