Description
技术领域technical field

The causes of the disease include cervical disc herniation, ligament thickening, spinal canal stenosis, trauma, etc. Some cervical spondylosis can be treated with posterior cervical spinal canal expansion and plastic surgery to obtain good therapeutic effects.
现有颈后路椎管扩大减压治疗术包括单开门成型、双开门成型、全椎板切除等减压方式，手术过程中需要采用相应的固定板对椎板进行支撑固定。现有固定板用于上述减压成型手术普遍存在成型不彻底、开门轴断裂、颈椎轴性痛等并发症，影响手术疗效。Existing posterior cervical spinal canal enlargement and decompression therapy includes single-door molding, double-door molding, and total laminectomy. Corresponding fixing plates are required to support and fix the lamina during the operation. Complications such as incomplete molding, fracture of the door opening shaft, and axial pain of the cervical spine commonly exist in the existing fixation plate used in the above-mentioned decompression molding operation, which affect the curative effect of the operation.
针对全椎板减压治疗术，缺少肌肉韧带支撑结构，术中肌肉韧带与颈椎棘突分离后会导致术后韧带等软组织附着性降低、支撑不到位导致颈椎稳定性降低、畸形等发生。For total laminar decompression therapy, there is a lack of muscle and ligament support structure. The separation of muscle and ligament from the cervical spinous process will lead to a decrease in the adhesion of soft tissues such as ligaments after surgery, and insufficient support will lead to a decrease in the stability of the cervical spine and deformity.
