2 Product description

2.1 Construction and Function

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  Ergo  helps  the  patient  perform  everyday  tasks  in  combination  with  other  prosthetic  components  of
the Axon-Bus prosthesis solution, such as the 8E500 Michelangelo hand.
A lithium-ion battery integrated into the product provides the required energy. 
If the elbow joint is switched off or the battery is depleted, the pull cable can be used to lock and unlock the elbow
joint in any position, even when loaded.

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.

Forearm cable

The forearm cable establishes the electrical connection between the product and the terminal device. The cable is
rolled up in the forearm of the elbow joint on delivery and can be replaced in case of damage.

Lock

Releasing and locking the elbow joint is automated according to operating situations, the applied load and the con­
trol signal generated by the patient by means of the electronically controlled locking drive.
