Patent ID: 8388625

Claim:
Support orthopaedic device for a knee joint, comprising a first anchoring device and a second anchoring device, arranged to be integrally associated respectively with a proximal bone and a distal bone of a lower limb connected among themselves by a knee joint, a proximal connector and a distal connector, articulated among themselves and respectively intended to be directly connected to said first and a second anchoring devices, a first rod and a second rod hinged, according to hinging axes normal to a median excursion plane of the orthopaedic device, to the proximal connector and to the distal connector so as to form with them a four-bar linkage; said four-bar linkage being planarly mobile according to a plane parallel to the excursion plane between a main configuration corresponding to an extended position of the knee joint and a plurality of secondary configurations corresponding to a different degree of bending of the knee joint, the relative motion imposed to the proximal and distal connectors by the four-bar linkage being consistent with the physiological movement of the knee joint, wherein said proximal connector presents, in correspondence with one of its distal ends, a reference hole, normal to the excursion plane, intended to temporarily house a guide thread integral with the proximal bone to allow the accurate positioning of the proximal connector with respect to the bone, wherein the device comprises first means to lock arranged to allow the locking of the four-bar linkage in the main configuration or in any one of its secondary configurations, and wherein at least one of the first and second rods has a first transversal threaded hole with axis normal to the excursion plane of the device; the first means to lock comprising a locking screw, insertable into the first transversal hole and into a slot of a first septum integral with one of the distal or proximal connectors; said locking screw being clampable against a wall of the first septum to lock the four-bar linkage in a wanted configuration.
