Abstract:
The WILMER Passive Hand Prosthesis is developed for children aged one through five
years. This harnessless hand prosthesis aims primarily at giving the child two arms of
equal length. The hand features an easy to control passive prehension function. The
movements of the fingers are mechanically coupled to the movements of the thumb. By
pressing an object against the fingertips, the hand opens. By slightly tilting the object, it
can be grasped. The hand prosthesis can be mounted in a passive friction wrist rotation
prosthesis, available in different outer diameters. The hand features a low mass
construction, which proved to be very robust and reliable in clinical tests. For the age
group mentioned the WILMER Passive Hand Prosthesis is one of the very few available
with a prehensile function. It stands out in functionality and in cosmetics as compared
to other passive hand prostheses on the market.
