A device for lumbar and knee recovery, the device comprising:
- a main chassis;
- a rotatable chassis pivotally coupled to the main chassis;
- a tilt actuator mounted between the main chassis and the rotatable chassis, the tilt actuator configured to drive a rotational motion of the rotatable chassis relative to the main chassis about a tilt axis;
- an upper traction assembly comprising:
- an upper sliding frame slidably mounted on the rotatable chassis, the upper sliding frame slidable relative to the rotatable chassis along a first axis, the first axis perpendicular to the tilt axis;
- a first linear actuator coupled between the rotatable chassis and the upper sliding frame, the first linear actuator configured to drive a sliding motion of the upper sliding frame relative to the rotatable chassis;
- a lower traction assembly comprising:
- a horizontal sliding frame slidably mounted on the rotatable chassis, the horizontal sliding frame configured to be slidable relative to the rotatable chassis along the first axis;
- a second linear actuator coupled between the rotatable chassis and the horizontal sliding frame, the second linear actuator configured to drive a sliding motion of the horizontal sliding frame relative to the rotatable chassis;
- a vertical sliding frame slidably mounted on the horizontal sliding frame, the vertical sliding frame configured to be slidable relative to the horizontal sliding frame along a second axis, the second axis perpendicular to both the first axis and the tilt axis;
- a third linear actuator coupled between the horizontal sliding frame and the vertical sliding frame, the third linear actuator configured to drive a sliding motion of the vertical sliding frame relative to the horizontal sliding frame;
- and
- a seat rotatably mounted on the vertical sliding frame, a plane of the seat parallel with the second axis and perpendicular to the first axis, the seat rotatable relative to the vertical sliding frame about a rotational axis parallel with the first axis;
- and
- an upper body fixing mechanism mounted on the rotatable chassis, the upper body fixing mechanism comprising:
- a support bridge mounted across the upper sliding frame, the support bridge comprising two legs attached to and extended from the lateral sides of the upper sliding frame and a cross beam attached across distal ends of the two legs;
- a pair of attachment points on the cross beam;
- a pair of corresponding attach points on the lateral sides of the upper sliding frame;
- and
- a pair of belts mounted between the pair of attachment points on the cross beam and the pair of corresponding attach points on the upper sliding frame, the pair of belts configured to extend over respective shoulders going around respective armpits of a patient responsive to a patient positioned over the upper sliding frame.
