The invention relates to an artificial joint (1), in particular an artificial hand, comprising several bodies (2, 3), connected to each other by means of joints. The individual bodies (2, 3) are connected to each other by means of an elastic connecting element (4) such as to swivel about several axes. A tensile force is introduced by means of a tractive mechanism (8, 9) for the respective retraction and extension of each body (2, 3). According to the invention, a high loading for the transfer of large forces at any joint position and a number of degrees of freedom for various gripping functions may be achieved, whereby the joint gap (7), between adjacent joint surfaces (5, 6), may be reduced where necessary, by means of the tractive mechanism (8, 9), such that the desired number of degrees of freedom can be achieved with a simultaneous stiffening of the joint (1). |
