2.0 Prosthesis fabrication
The i-limb hand is assembled in combination with a
socket made to the requirements of the individual user.
When fabricating the prosthesis for the i-limb
®
hand
consideration should be given to:
a. Electrode positioning
b. Battery placement, size and configuration
c. Charge port placement
d. Socket length and overall length of the prosthesis
Precautions should be taken against sweat entering the
components, as sweat ingress can cause damage and
compromise the function of the prosthesis.
The use of carbon fiber is not recom-
mended due to electrical conductivity.
2.1 Socket materials
The socket design and materials used for the prosthesis
are based on the clients presentation and skin condition.
Typical inner socket materials include silicone, thermo-
plastic and laminate. The outer socket is primarily lami-
nate.
For a standard prosthesis, a minimum expected layup
would be;
Inner socket: 2 layers of perlon stockinette, 2 layers of
nyglass and 2 layers of perlon stockinette.
Outer socket: 4 layers of nyglass and 2 layers of perlon
stockinette.
The build of each prosthesis should be adjusted specifi-
cally to meet the individuals requirements.
It is not recommended to use carbon fiber within a myo-
electric prosthesis.
