| 摘要 |
The invention relates to a motorised multi-articulated prosthetic hand which is fully controllable by the user, of the type formed by a forearm section defining a connection socket on the distal end thereof, which is suitable for receiving and firmly securing the stump of the forearm of an amputated patient, and comprising, on the proximal end, a connection means defining a wrist section which is pivotably coupled to the prosthetic hand, said hand comprising a plurality of articulated fingers. The invention is characterised in that the thumb is made up of a metacarpal, a proximal phalange and a distal phalange which are interconnected by means of articulated ball-and-socket-type connections, and the index, middle, ring and little ringer are made up of a proximal phalange, an intermediate phalange and a distal phalange, which are interconnected by means of articulated ball-and-socket-type connections, where said phalanges and said metacarpal element comprise four intercommunicating channels used to conduct actuating cables which are guided through a plurality of conduits distributed throughout the hand until they are housed in the forearm section where the ends thereof are connected on pulleys actuated by motors of an electromechanical actuating system in response to signals from myoelectric surface sensors. |
