Patent ID: 7282035

Claim:
A physiotherapeutic apparatus for restoring lower limb function, comprising (a) a bed, the bed having thereon a threaded rod, an actuating device, the actuating device being connected to the threaded rod for causing rotational motion of the threaded rod; a circuit controller, the circuit controller being connected to the actuating device for controlling motion of the actuating device; two lateral guide rails, and a lengthways-extending guide rail; the threaded rod, the lateral guide rails, and the lengthways-extending guide rail being parallel; (b) a sliding mechanism, the sliding mechanism being equipped with: a plurality of longitudinally rolling wheels fitted in and rolling along the lengthways-extending guide rail, a plurality of lateral rolling wheels fitted in and rolling along each of the lateral guide rails, and a threaded sleeve, the threaded sleeve being positioned around the threaded rod so that rotational motion of the threaded rod will cause forward and backward linear displacement of the sliding mechanism; (c) a connecting rod combination, the connecting rod combination being pivoted to the bed at one end, and pivoted to the sliding mechanism at other end thereof.
