The invention discloses an intervertebral fusion fixator. The intervertebral fusion fixator is applied in intervertebral disc operations, arranged at intervertebral space between an upper pyramid boneand a lower pyramid bone, and characterized by comprising a supporting fusion part and a spiral fixing part in clamped connection with the supporting fusion part, the supporting fusion part is a metal bone trabecular structure printed stereoscopically, the metal bone trabecular structure is provided with a plurality of metal micro pores with bore diameter of 300-500 micrometers, and further internally provided with one or more bone grafting grooves; the spiral fixing part is provided with a thread, the tail portion of the spiral fixing part is provided with an inner hexagon hole, and the outer diameter of the thread is larger than the thickness of the supporting fusion part with 3-4 millimeters. Compared with the prior art, the intervertebral fusion fixator has the advantages that the upper and lower pyramids can be effectively fixed to prevent the olisthy and displacement of the pyramids, cervical thoracic lumbar discectomy bone grafting fusion and intervertebral fixation operationscan be completed minimally invasively at one time, the intervertebral fusion fixator is more convenient and practical than an existing cervical vertebra low indentation fusion device, the operation time can be obviously shortened, the risks are greatly reduced, and the fusion rate is higher.
