Description
Technical field
This utility model relates to Invasive lumbar fusion device, particularly a kind of PEEK cervical fusion cage.
Background technology
Current intervertebral disc of cervical vertebra degenerative disorders, spinal canal stenosis, previously Fusion failure, pseudarthrosis etc. are cases common clinically.Current therapeutic method of surgery is mainly implants cervical steel plate and common cervical fusion cage at diseased region.But product mostly in the market is common cervical fusion cage, its stability is bad, fusion device and Cervical Fusion poor.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of PEEK cervical fusion cage.
This utility model solves the technical scheme that its technical problem adopts: described a kind of PEEK cervical fusion cage, comprises fusion device body, and its upper and lower surface is provided with anti-skidding swings to sawtooth; This fusion device body has bone grafting cavity, and described fusion device body end face head is provided with development needle.Described bone grafting cavity is the cavity vertically running through described fusion device body, and described fusion device body side is provided with the bone grafting hole with described bone grafting cavity connects; Described fusion device body end face is arc, and itself and cervical vertebrae physiological radian match, and is provided with screwed hole after described fusion device body.
The cambered surface of fusion device body end face contributes to fitting with human cervical spine, and make fusion device body and human cervical spine amalgamation better, stability is high.Described screwed hole is convenient to coordinate with steel plate, and operation easier is low, and operating time is short.
As the better improvement of the design, described bone grafting hole is oval hole.Oval hole is convenient to fill bone, reduces operation easier.
As the better improvement of the design, described fusion device body end face both sides are arranged with bar-shaped trough.Described bar-shaped trough facilitates titanium silk to insert when implanting, and plays the effect of guiding, fusion device is implanted more accurate.
As the better improvement of the design, described in swing to the transverse teeth that sawtooth is many row's arrangements.Many rows transverse teeth is beneficial to the bonding strength improving fusion device body and human cervical spine, and its stability is better.
As the better improvement of the design, described fusion device body is PEEK material.The fusion device body of described PEEK material is simple for production, good biocompatibility, and lonizing radiation can penetrate and assess the situation of osteogenesis.
The beneficial effects of the utility model are: this utility model utilizes the cambered surface of fusion device body end face to contribute to fitting with human cervical spine, and make fusion device body and human cervical spine amalgamation better, stability is high.

The cambered surface of fusion device body 1 end face contributes to fitting with human cervical spine, and make fusion device body 1 better with human cervical spine amalgamation, stability is high.Described screwed hole 7 is convenient to coordinate with steel plate, and operation easier is low, and operating time is short.
As the better improvement of the design, described bone grafting hole 6 is oval hole.Oval hole is convenient to fill bone, reduces operation easier.
As the better improvement of the design, described fusion device body 1 end face both sides are arranged with bar-shaped trough 3.Described bar-shaped trough 3 facilitates titanium silk to insert when implanting, and plays the effect of guiding, fusion device is implanted more accurate.
As the better improvement of the design, described in swing to the transverse teeth that sawtooth 5 is many row's arrangements.Many rows transverse teeth is beneficial to the bonding strength improving fusion device body 1 and human cervical spine, and its stability is better.
As the better improvement of the design, described fusion device body 1 is PEEK material.The fusion device body 1 of described PEEK material is simple for production, good biocompatibility, and lonizing radiation can penetrate and assess the situation of osteogenesis.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
