Device for determining a load axis of an extremity

For obtaining bearing axis (5) method, the bearing axis of the rotatable the supporting one end of the fixing centre of rotating faces (1) are distributed via the first tail; the centre of the rotating that to achieve around the mechanical installed between the measuring, specifically to the hip nest's centre of rotating, and end of the is used to the thighbone, the measuring drew support with is used for measuring the end of a (1) measuring point installed between the optical with measuring device (7) in rotary position, 8, 9) with a rigid fixing, the end of the edge (1) andThe multi-point sensor (8) measuring multiple measuring point with ten-finger each rotating position, a measuring in multiple measuring point installed between to applies at least one set in multiple preset positions; the combined with ten-finger of belongs to the centre of the one-fourth position, and is attached in the centre of the position of the measuring button u-shaped set, a calculate bearing axis (5).
