Abstract

Symbrachydactyly is a congenital pathology characterized by the deformation or absence of finger phalanges of the hand, as well as a deformity in the palm. Consequently, affected people have difficulties performing daily activities, in addition hand prostheses are usually designed for total amputations or do not consider the finger remnants, for this reason, this research work presents a prototype of a customized active partial hand prosthesis. As a starting point, a 3D scanning of the affected hand is carried out to be processed in CAD software, then a socket is designed and printed in a flexible material to couple the affected hand with the prosthesis. For the motion performing, prosthetic fingers contemplate a four-bar mechanism, 4R, to mimic as far as possible the natural hand movement. Preliminary tests show that the prototype is able to adapt to the deformity of the hand and to performing the cylindrical grip.
