Anterior cervical locking fusion cage

The utility model belongs to medical instruments for the orthopedics department, and particularly relates to an anterior cervical locking fusion cage which is characterized in that a fusion hole which is through front and back is formed in a main body and is used as a bone grafting space; a rotatable fixing device composed of two bolts and two blades is arranged on the front portion of the fusion cage body, the blades are connected together through the bolts, and the blades can be rotated through the bolts to achieve locking. The head of the bolt completely sinks into the fusion cage body, so that incisura can be reduced, and a better fusion effect is achieved. The upper surface of the main body is arc-shaped, the lower surface of the main body is wedge-shaped, and the upper surface and the lower surface are provided with anti-skidding teeth so as to enhance stability. The cervical vertebra locking fusion cage is implanted into an intervertebral space, the two blades respectively rotate by 90 degrees and are
