本发明涉及医疗器械技术领域，尤其是涉及一种颈椎后路板。The invention relates to the technical field of medical instruments, in particular to a posterior cervical plate.
背景技术Background technique
脊髓性颈椎病是脊髓压迫症之一，严重者可致残，占全部颈椎病的10％—15％。部分脊髓型颈椎病需要进行椎管扩大手术减压治疗，颈椎后路单开门椎管扩大成形术是治疗脊髓型颈椎病最有效的方法之一，但传统的内固定方法易出现开门再关门现象，造成颈椎椎管再狭窄以及“轴性症状”，影响手术疗效。随着科技的发展，市面上出现了微型钛板，但这种技术只能固定开门侧的椎体，由于手术时需要先将病变部位颈椎一侧椎体切开，另一侧切开凹槽进行微旋转，医生的个人习惯、手术方法、手术力度等因素的差异，可能造成门轴侧椎体的断裂，传统开门手术需要将颈椎棘突和附着在其上的韧带全部或部分切除，术后易引发颈椎不稳、颈椎活动范围减小等症状；或需要增加钢丝线缆、缝线等植入物进行固定，增加对周围组织、神经的刺激或损伤；同时颈部的活动亦会导致钢丝线缆、缝线对周围软组织形成切割效应，增加术后感染及引发炎症等风险，给患者带来痛苦。Cervical spondylotic myelopathy is one of spinal cord compression diseases, severe cases can be disabled, accounting for 10%-15% of all cervical spondylosis. Some cervical spondylotic myelopathy requires spinal canal enlargement surgery decompression treatment. Posterior cervical single-door laminoplasty is one of the most effective methods for the treatment of cervical spondylotic myelopathy, but the traditional internal fixation method is prone to opening and closing the door , resulting in restenosis of the cervical spinal canal and "axial symptoms", affecting the efficacy of surgery. With the development of science and technology, miniature titanium plates have appeared on the market, but this technology can only fix the vertebral body on the side of the door, because the cervical vertebral body of the diseased part needs to be incised on one side and the groove on the other side should be incised first. For micro-rotation, differences in the doctor's personal habits, surgical methods, surgical strength and other factors may cause fracture of the vertebral body on the side of the portal axis. Traditional open-door surgery requires complete or partial resection of the cervical spinous process and the attached ligaments. Afterwards, it is easy to cause symptoms such as cervical spine instability and decreased range of motion of the cervical spine; or it is necessary to add steel wires, sutures and other implants for fixation, which will increase stimulation or damage to surrounding tissues and nerves; at the same time, neck activities will also lead to Steel wire cables and sutures have a cutting effect on the surrounding soft tissue, increasing the risk of postoperative infection and inflammation, and causing pain to patients.
