Atlantoaxial lateral mass joint distraction reduction device

The invention discloses an atlantoaxial lateral mass joint distraction reduction device, and belongs to the technical field of medical instruments. According to the atlantoaxial lateral mass joint distraction reduction device, the two distraction devices are arranged at the bottom of the gantry frame, when an atlantoaxial lateral mass is distraction, double-side asymmetric distraction can be achieved, the force line of the restored cervical vertebra can be perpendicular to the horizontal plane through double-side asymmetric distraction, and the phenomenon that the torticollis occurs after an operation is avoided; through the arrangement of a second cervical spine process fixing structure and a fixing buckle, the device can form a structure similar to a tripod, and the stability of the device is better; due to the fact that the anti-skid protruding thorns are arranged on the surface of the dilator and the double-balloon design is adopted, it can be guaranteed that the dilator is evenly stressed in the dilation
