Emerge aesthetic of a passive prehension for children

摘要

The passive hand prosthesis is for a congenitally or traumatically handicapped child, having an adjustment at the proximal end allowing simultaneous regulation from outside both of the grip and traction force exerted on the rope. The adjustment mechanism can comprise a bolt (10) screwing into a nut (8) and acting on a compression spring (9). A stationary but easily detachable thumb(P) can be provided, to allow easy fitting of a glove. The prosthesis can be arranged to open without actuation of the rope, and the thumb (P) and fingers (D) can be interchangeable, allowing the same mechanism to be used for hands of different sizes.
