2 Description of the Design and Individual Components
Your prosthesis primarily consists of a custom inner socket which fits over your residual limb and
encompasses the joint, the covered outer socket with harness and the connected DynamicArm
with the System Electric Hand.
A consistently good fit of your prosthetic socket can only be maintained if the volume of your
residual limb remains constant. Further information is found under volume fluctuations in Section
4 "Medical and Therapeutic Aspects".
In accordance with your indications and personal requirements, you have received a prosthesis of
the following design:
Harness:
The harness helps to hold the prosthesis on the body. The harness runs below the
armpit of the sound side.
Liner:
A custom liner improves the connection between your residual limb and the prosthesis.
DynamicArm:
The DynamicArm is an electrically controlled high-performance elbow. The electric
motors and the vario-gear are monitored by sensors and have been adapted to your individual
control signals. Your Ottobock team has selected the control options best suited to you and
adjusted them to your individual needs. The electronically controlled AFB (Automatic Forearm
Balance) flexion aid saves energy and enables a free-swing phase that appears natural. An integ
rated lithium-ion battery provides enough power for one full day.
System Electric Hand:
The System Electric Hand is used to perform gripping functions. It con
tains the drive unit (electric motor, gear), sensors if applicable and the control unit. The inner
hand covers the technical components and, together with the individual cosmetic glove, creates a
natural appearance. The quick-disconnect wrist allows you to exchange the System Electric Hand
for a gripper.
INFORMATION
The System Electric Hand features an on/off switch. Turn off the System Electric Hand to pre
vent unnecessary power consumption or accidental opening of the hand.
Electrodes:
The inner socket electrodes on the skin capture the myo-signals from the residual
limb muscles and amplify them as socket impulses for the electric motors. The Ottobock team has
made individual adjustments to meet your requirements.
Battery charger:
The charger is used to charge the built-in lithium-ion battery. It must be connec
ted to a 220-V mains outlet. For more information please refer to the battery charger instructions
for use.
Cosmetic glove:
The cosmetic glove gives the prosthetic hand a natural appearance by imitating
the anatomical structures. For more information please refer to the cosmetic glove instructions for
use.
