Cervical biological composite steel plate

Abstract

The invention relates to a cervical vertebra biological composite steel plate. The composite steel plate comprises a fixing steel plate and a cushion plate, wherein the fixing steel plate is provided with a fixing steel plate body, pin holes, a window, locking devices, locking device grooves and buckling holes; the pin holes are formed in the four corners of each section of steel plate; the window is formed in the middle part of each section of steel plate; the locking device grooves are formed in one side of the pin holes; the locking devices are arranged in the locking device grooves; the buckling holes are formed in the rear part edge of the fixing steel plate body; the cushion plate is provided with a cushion plate body, a placing groove, buckling blocks and windows; the windows of the cushion plate are arranged on the middle part of each section of steel plate; the buckling blocks are arranged at the edge of the placing groove; and the fixing steel plate is arranged in the placing groove. The composite steel plate has the advantages that the problem that single or two adjacent intervertebral cervical pulps are compressed is solved, and normal physiological curvature of a cervical vertebra is restored; multi-segment fusion is avoided, wound is reduced, and normal intervertebral space is not occupied; and an absorbable material is adopted and the material is degraded within one year after surgery, so that long-term prognosis of a patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a biological composite steel plate for cervical spine. Background technique [0002] At present, the commonly used anterior cervical screw-plate system in clinical practice is the Skyline anterior cervical fixation system, which is suitable for the fixation of single cortical screws in front of the vertebral body, thereby stabilizing the C2 to C7 segmental cervical spine. Specific clinical indications include: 1. Instability caused by trauma; 2. Instability associated with repair of cervical lordosis and cervical kyphosis; 3. Instability associated with pseudarthrosis formed by previous failed cervical spine surgery; 4. 1. Instability associated with large-scale repair and reconstruction surgery for primary tumors and metastatic malignancies; 5. Single-segment or multiple Instability associated with segmental corpectomy. [0003] However, in the face of patients with a ...

Problems solved by technology

However, this combined steel plate in the anterior cervical spine can only control the width of the steel plate through combination, and cannot play the role of the composite steel plate of the present invention.

[0006] Therefore, there is an urgent need for an anterior cervical fixation plate that can be used for a single or adjacent two cervical disc herniation combined with straightening or even reverse curvature of the cervical spine, but there is no report about this plate at present
