摘要:
FIELD: medicine.SUBSTANCE: group of inventions relates to the field of medical technology, namely to the active hand and forearm prostheses. Arm prosthesis for patients with a degree of amputation from the fingers to the forearm includes a hand prosthesis including the system of cables and pulleys, the forearm prosthesis and the wrist joint prothesis that connects the hand prosthesis to the forearm prosthesis. Wrist joint is formed by joining the hand and forearm by means of two flexible tubes with thickenings at the ends, each of which is fixed at one end in the wrist prosthesis, the other in the forearm prosthesis. Forearm contains the distal and proximal segments, which are connected by two flexible tubes that are fixed at both ends in the segments to be joined. Hand blocking device is installed in the hand. In the proximal segment of the forearm, there is the tension mechanism for the traction cable of the hand prosthesis and the hand unlocking angle regulator, which is a plate fixed to the surface of the proximal segment and configured with the possibility to extend beyond the segment and affect the hand blocking device installed, which is installed in the hand prosthesis. Hand prosthesis for the mentioned arm prosthesis includes the hand blocking device and the mechanical hand that comprises a metacarpus, the artificial fingers, which is connected to the metacarpus by means of joints and formed by the phalanges with channels that are connected with joints, through their channels the cables are stretched, the ends of which are fixed on the distal phalanxes and at the ends of the pulleys, which are connected by means of a cable with the cable tensioning unit. Joint, which connects the adjacent phalanges of the fingers and the phalanx with the metacarpus is an elastic elongated element with thickenings at the ends. On the metacarpus in the area of the base of the thumb there is a recess with coaxially fixed protrusions, in which the rotator is mounted with the fo
