Patent ID: 8020559

Claim:
Device for the angular positioning of a limb of a patient resting on an operating table having a longitudinal axis, comprising means of positioning a cradle supporting the limb of the patient with respect to the lateral guide rails of the operating table, wherein said means of positioning comprise: means of securing said means of positioning the cradle as well on one or the other of the two lateral guide rails of the operating table; means of positioning said cradle according to an axis contained in a plane parallel to a plane defined by the operating table, and perpendicular to the longitudinal axis of the operating table; said means of positioning said cradle further comprising: a base plate situated in a plane parallel to that defined by the operating table, which base plate being capable of moving parallel to itself in sliding connection with the above-mentioned means of securing; a bracket, secured to the above-mentioned base plate, comprising a rotation shaft, situated close to the upper part of said bracket, and whereof the rotation shaft has an axis situated in a plane parallel to said base plate, perpendicular to the longitudinal axis of the operating table, and parallel to the plane defined by the operating table; an arm support, mounted to and rotatable about said rotation shaft and driven rotationally in a plane perpendicular to said base plate by a drive mechanism; a guide slot, mounted secured to the above-mentioned arm support, on the side opposite to the above-mentioned drive mechanism, and capable of guiding a sliding block in a plane perpendicular to said base plate; an arm, secured to said sliding block, having an axis parallel to the longitudinal axis of the operating table; a hub, whereof the axis is situated in a plane parallel to said base plate and perpendicular to the longitudinal axis of the operating table, and capable of sliding through said arm according to the main axis of said arm; a shaft, mounted to and rotatable about the above-mentioned hub and move translationally in the above-mentioned hub, whereof the axis is collinear with the above-mentioned axis of the hub, and supporting at one of its ends the above-mentioned cradle, wherein the shaft supporting the cradle is able to tilt the cradle in a plane perpendicular to the plane defined by the operating table.
