2 Product description

2.1 Design
2.2 Function
The product is a myoelectrically controlled elbow joint driven by an electric motor. It helps the wearer perform
everyday tasks in combination with other prosthetic components (see Page 5).
A Li-Ion battery integrated into the product provides the energy required. The "646C42=V* ElbowSoft" software is
used for the patient-specific adjustment of the product.
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.
In new condition, the product can lift a load of up to 5 kg. Once this load is exceeded, the joint will be locked. Flex­
ion and extension are only possible again after the load is reduced.
2.2.1 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
