Abstract:
The present disclosure provides a prosthetic thumb. The prosthetic thumb employs a specialized thumb rotating rack for matched mounting of the prosthetic thumb; the thumb rotating rack is connected between the thumb front support and the thumb back support through the coaxially arranged thumb front supporting shaft and thumb back supporting shaft; and the lead connected with the motor in the prosthetic thumb passes through the lead through hole through the thumb rotating rack open slot and no longer passes through a side face as in the prior art, so that when the thumb rotating rack is rotated due to opposite palm and side palm operation of the prosthetic thumb, the lead is not pulled and bent due to the rotation of the thumb rotating rack, and the service life of the lead is prolonged.

Claim (Index 1):
A prosthetic thumb, comprising a thumb mounting rack, a thumb worm gear, a thumb rotating shaft, a thumb base joint rack, a thumb base knuckle, a thumb proximal knuckle, a thumb distal knuckle, a thumb rotating rack, a thumb front support and a thumb back support;\n the thumb worm gear is fixed on the thumb mounting rack; the thumb base joint rack is rotatably connected to the thumb worm gear through a thumb rotating shaft; the thumb base knuckle is fixed on the thumb base joint rack; the thumb proximal knuckle is fixed on the thumb base knuckle; the thumb distal knuckle is fixed on the thumb proximal knuckle; a thumb motor reducer assembly, a thumb first bevel gear, a thumb second bevel gear and a thumb worm are arranged in the thumb base joint rack; the thumb motor reducer assembly sequentially drive the thumb first bevel gear, the thumb second bevel gear and the thumb worm to rotate, the thumb worm gear is engaged with the thumb worm; the thumb rotating rack is provided with a thumb rotating rack open slot, the thumb mounting rack is positioned in the thumb rotating rack open slot and fixed on the thumb rotating rack, the thumb front supporting shaft and the thumb back supporting shaft are coaxially connected at two ends of the thumb rotating rack respectively, the back end of the thumb front supporting shaft is positioned in the thumb rotating rack open slot, the thumb front supporting shaft is inserted in the thumb front support, the thumb back supporting shaft is inserted in the thumb back support, the thumb front supporting shaft is internally provided with a penetrating lead through hole along the axial direction of the thumb front supporting shaft, and a lead which is connected with a motor in the prosthetic thumb is inserted in the lead through hole, through the thumb rotating rack open slot.
