| dc.description.abstract |
A new type prosthetic prehensor for children aged 4 – 9 has been designed, constructed
and build in an attempt to improve the appearance of the split-hook prosthesis. The
new prehensor is a mechanically operated voluntary opening device. All mechanical
parts are within the frame, and covered by a polyurethane cosmetic cover, which can
be made in almost any color desired.
Clinical testing of the prehensor by 4 children with a total time of use of over 170
months, revealed the mechanism to be very robust and reliable. The colorful hook cover
is highly appreciated by the children.
Encouraged by this success, a second larger size has been made intended for children
aged 7 - 14. This medium size prehensor is now in clinical use by 1 child for over
12 months. Again, the appearance of the hook is highly appreciated, and again, the
mechanism proves to be very reliable.
