The bushing is mounted on a bar so as to be movable along the bar and rotable thereabout, with the bar being disposed radially relative to the arch defining the shape of the plate, and being joined to the ring by means of a spatial hinge having two degrees of freedom and mounted on the ring so as to be movable therealong. The extremity of the stereotaxic instrument is positioned at a point being the projection of the curvature center of the arch defining the shape of the plate on the axis of the bar.
