Abstract

The invention discloses an oblique transverse fixed steel plate for anterior cervical vertebrae, which comprises a main plate and a sub-plate. A plurality of through holes are arranged in the middle of the main plate, and a threaded hole is respectively arranged between the upper and lower edges of the main plate and the through holes in the middle. , There are at least 4 auxiliary boards, and at least 2 auxiliary boards are arranged on the left and right sides of the main board body respectively. The auxiliary boards are hinged with the main board. There is a spike on the inner side of the auxiliary plate. The length of the spike ranges from 2mm to 3mm. The width of the body and the lower part of the main plate are the same. The middle part of the main plate is narrower than the upper and lower parts. The main plate is made of titanium alloy. material, the sub-plate is made of titanium alloy material. Compared with the traditional cervical vertebra anterior fixation steel plate, the overall structure of the invention is simple in structure and convenient in operation, and the overall structure is more stable and the fixation strength is stronger.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an oblique transverse fixed steel plate for anterior cervical spine. Background technique [0002] Anterior cervical plate fixation is a commonly used internal fixation device in anterior cervical fusion surgery. After resection of the intervertebral disc and anterior longitudinal ligament, decompression and preparation of the bone graft bed, a fusion cage is implanted, and finally the plate is placed and the screws are tightened. [0003] The fusion cage mainly plays the role of support, while the steel plate as the bone plate mainly plays the role of stability and fixation. [0004] After the operation, the human body will still move the cervical spine, including several movements such as forward flexion, backward extension, left and right lateral flexion, and left and right rotation. In the long-term repeated existence of these movements, the steel plate may loosen and the scre...
