ELECTRICALLY DRIVEN ARTIFICIAL HAND FOR UPPER EXTREMITY PROSTHESIS

An artificial hand for upper extremity prosthesis, comprising a reversible electric drive controlled by, for example, bioelectric potentials produced by muscles, and kinematically associated with an actuating lever of the thumb and with at least one for the thumb-opposing fingers. The mechanical lin...

Beschreibung
Zusammenfassung:	An artificial hand for upper extremity prosthesis, comprising a reversible electric drive controlled by, for example, bioelectric potentials produced by muscles, and kinematically associated with an actuating lever of the thumb and with at least one for the thumb-opposing fingers. The mechanical linkage interconnecting the electric drive with said thumb-opposing finger is essentially a disengageable unidirectional linkage capable of ensuring that the positive effect of the electric drive upon said finger occurs solely in the direction of extension thereof. The thumb-opposing finger is coupled to a spring actuating it in the direction of flexion thereof, and is provided with a lock to prevent it from being extended under any external force.
