Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of cervical vertebra uncovertebral joint fusion device.
Background technology
Cervical spinal fusion is widely used in treating various cervical spondylosis and has reached over half a century, traditional intervertebral fusion
Device (cage) is expensive, and up to 1 piece of tens thousand of units, traditional discectomy Intervertebral fusion emphasizes " vertebral fusion " ---
, from the growth healing of upper hypocentrum central authorities, yet with anatomical physiology reason, upper hypocentrum spacing is from farther out, and possible blood for bone
The other reasonses such as fortune, " the creeping substitution healing journey " of bone are very long and hard, and healing time is longer (when patient needs to wear longer
Between brace until fusion), and destroy soleplate it is postoperative with prosthese sink displacement risk.
The content of the invention
The present invention is intended to provide a kind of cervical vertebra uncovertebral joint fusion device, reduces cost, time of fusion are short, reduce neck brace pendant
The time is worn, patient comfort is improve, soleplate of need not polishing, operating time shorten, postoperative prosthese sinking risk reduction.
To reach above-mentioned purpose, the present invention employs the following technical solutions realization：
Flexibly support between cervical vertebra uncovertebral joint fusion device disclosed by the invention, including uncovertebral joint fusion part and vertebral body
Body, lateral dimension of the lateral dimension of the rear end of elastic support more than front end, the uncovertebral joint fusion portion between the vertebral body
Part has two, is connected between vertebral body on the left and right lateral surface of elastic support, and uncovertebral joint fusion part is that tubular is netted
Structure, uncovertebral joint bone-graft fusion part are connected with baffle plate away from the side of elastic support between vertebral body.
During operation, polishing or uncovertebral joint of not polishing, be put in uncovertebral joint bone-graft fusion part clogged from
Body or artificial bone implanting device, baffle plate are separated by with intervertebral foramina, it is to avoid bone grafting is grown in intervertebral foramina.
Further, between the vertebral body, the top surface of elastic support and bottom surface are equipped with raised agnail and/or circle is convex
Rise.
Preferably, the baffle plate is inclined to elastic support rear end between vertebral body.
Further, between the vertebral body, elastic support rear end is provided with draw-in groove.
Preferably, between the uncovertebral joint fusion part and vertebral body, the distance of elastic support front end is melted less than uncovertebral joint
Close the distance of elastic support rear end between part and vertebral body.
Preferably, the material of the uncovertebral joint fusion part is titanium alloy.Metallic titanium alloy material, can be used for image
Learn positioning to evaluate, and do not affect patient's nuclear magnetic resonance check.
Preferably, between the vertebral body, the material of elastic support is polyether-ether-ketone；Its elastic modelling quantity is close with cortical bone, raw
The thing compatibility is good, with the intensity suitable with metal material and fatigue durability, can pass through x-ray, and MRI or CT examination will not produce puppet
Shadow.
Further, the developing mark of X-ray opaque is provided between the vertebral body in elastic support.
Preferably, the four trapezoidal rounding of angle.
Preferably, the baffle plate is titanium alloy sheet.
Beneficial effects of the present invention are as follows：
1st, to take full advantage of human cervical spine both sides uncovertebral joint adjacent relatively near for the present invention, and soft tissue blood is closed at uncovertebral joint
The cervical vertebra inherent advantage such as abundant is transported, implantation bone creeping substitution is grown soon apart from short, and soon, fusion rate is high for fusion.
2nd, bone-graft fusion is fast, therefore wears that the neck brace time is short, and patient experiences.
3rd, after discectomy, soleplate of need not polishing is easy to operate, save operating time and economic cost.
4th, uncovertebral joint fusion device does not destroy soleplate, and supporter adopts elastic support, and biomechanical property is good, under prosthese
Heavy risk reduction.
5th, supporter is designed for anatomical form, designs the soleplate form Design up and down according to compatriots so as to upper and lower soleplate
Laminating is more preferable.
6th, supporting body surface has the pawl and circular protrusions of projection, can prevent implant from shifting.
7th, supporter is polyetheretherketonematerials materials, and the imaging examination compatibility is good.
8th, at uncovertebral joint fusion, part adopts network structure, more favourable blood fortune and Bone Ingrowth.
9th, at uncovertebral joint fusion, after part, there is thin titanium alloy baffle plate in outside, can prevent bone grafting from growing into intervertebral foramina.

Fig. 2 is the front view of the present invention；
Fig. 3 is the rearview of the present invention；
In figure：Elastic support, 2- uncovertebral joints fusion part, 3- baffle plates, 4- draw-in grooves, 5- agnails, 6- circles between 1- vertebral bodys
Shape is raised.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing, the present invention is entered
Row is further described.
As shown in Figure 1, Figure 2, Figure 3 shows, cervical vertebra uncovertebral joint fusion device disclosed by the invention, including uncovertebral joint merges part
Elastic support 1 between 2 and vertebral body, between vertebral body, elastic support 1 is designed using anatomical form, to fit with upper and lower soleplate more preferably, vertebra
Between body, the material of elastic support 1 adopts polyether-ether-ketone, is provided with the developing mark of X-ray opaque, vertebra between vertebral body in elastic support 1
Between body, the cross section of elastic support 1 is similar to trapezoidal, and four rounding of angle, front end are small end, and between vertebral body, 1 rear end of elastic support is provided with
Draw-in groove 4, draw-in groove 4 are located at 1 rear end face of elastic support longitudinally through, the top surface of elastic support and bottom surface between vertebral body between vertebral body
It is laid with the agnail 5 or circular protrusions 6 of projection；Uncovertebral joint fusion part 2 has two, is connected to elasticity between vertebral body
Near the position of front end, uncovertebral joint merges part 2 for tubular network structure to two waist lateral surface of support body 1, uncovertebral joint
