The invention discloses a multi-degree-of-freedom external fixator. The key point of the technical solution is to include a fixed ring part and a telescopic connecting rod part. The two fixed ring parts are connected by six telescopic connecting rod parts. The fixed ring part is provided with Rotate the corner connector, the rotate corner connector includes a fixed ring connection part and a connecting rod connection part, the rotation axis of the fixed ring connection part and the fixed ring part is consistent with the length direction of the fixed ring connection part, and the connecting rod connection part The rotation axis connected with the telescopic connecting rod part is consistent with the length direction of the connecting part of the connecting rod; the connecting part of the fixed ring and the connecting part of the connecting rod are set at an angle, and the two ends of the telescopic connecting rod part are provided with rotating connectors , the telescopic connecting rod part is rotationally connected with the rotating connector, the rotational axis of the telescopic connecting rod part being rotationally connected with the rotating connector and the rotational axis of the connecting rod connecting part being rotationally connected with the rotating connector is arranged vertically. The fixing frame can effectively improve the flexibility during installation.
Description
Technical field [0001] The present invention relates to orthopedic correction, the technical field of rehabilitation equipment, and more specifically, it involves a multi-degree of immonal fixing frame. Background technique [0002] When surgical skeleton surgery, the fixing device is essential, and the conventional fixed way generally uses the steel sheet fixed, and there is now also a wound smaller external fixation treatment. Common external fixation devices are mainly an Ilizarov outer holder, Taylor skeleton. ILizarov technology uses multi-plane fine clue-tissue through limbs and bone tissues, and connects the ring holder. Taylor doctor improves the ILizarov external fixation system, inclined the six retractable extension rods, and can rotate around the direction of rotation at the connection point, as long as one of the length of the extended rod is adjusted, one The loop changes the position relative to another ring. [0003] However, both ends of the extension rod are con...
