Abstract
The invention discloses a cervical vertebra uncovertebral joint fusion cage which comprises uncovertebral joint fusion components and a vertebrae inter elastic supporting body. The cross section of the vertebrae inter elastic supporting body is trapezoidal, and the front end of the vertebrae inter elastic supporting body is a small end. The two uncovertebral joint fusion components are connected to two waist outer side surfaces of the vertebrae inter elastic supporting body respectively and are of a cylindrical mesh structure, and baffles are connected to the side faces, away from the vertebrae inter elastic supporting body, of the uncovertebral joint fusion components. The cervical vertebra uncovertebral joint fusion cage can reduce cost, the fusion time is short, the wearing time of a neck collar is shortened, the comfort level of a patient is improved, an end plate does not need to be ground, the surgical time is shortened, and the sinking risk of prostheses after an operation is reduced.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of cervical vertebra uncovertebral joint fusion device.
Background technology
Cervical spinal fusion is widely used in treating various cervical spondylosis and reaches over half a century, traditional BAK (cage) is expensive, reach 1 piece, tens thousand of unit, traditional discectomy Intervertebral fusion is emphasized " vertebral fusion "---bone is from the growth healing of upper hypocentrum central authorities, but due to anatomical physiology reason, upper hypocentrum spacing is far away, and the other reasons such as possible blood fortune, " the creeping substitution healing journey " of bone is very long and hard, healing time longer (needs of patients wear for extended periods brace is until merge), and destroy soleplate postoperative have prosthese sink displacement risk.
Summary of the invention
The present invention aims to provide a kind of cervical vertebra uncovertebral joint fusion device, and reduce costs, time of fusion is short, decreases neck brace wear time, improves patient comfort degree, and without the need to soleplate of polishing, operating time shortens, and postoperative prosthese sinking risk reduces.
For achieving the above object, the present invention realizes by the following technical solutions:
Cervical vertebra uncovertebral joint fusion device disclosed by the invention, comprise uncovertebral joint and merge elastic support between parts and vertebral body, between described vertebral body, the lateral dimension of the rear end of elastic support is greater than the lateral dimension of front end, described uncovertebral joint merges parts two, be connected on the left and right lateral surface of elastic support between vertebral body, it is tubular network structure that uncovertebral joint merges parts, and uncovertebral joint bone-graft fusion parts are connected with baffle plate away from the side of elastic support between vertebral body.
During operation, polishing or uncovertebral joint of not polishing, in uncovertebral joint bone-graft fusion parts, put into clogged autologous or artificial bone implanting device, baffle plate and intervertebral foramina are separated by, and avoid bone grafting to grow in intervertebral foramina.
Further, between described vertebral body, the end face of elastic support and bottom surface are equipped with protruding agnail and/or circular protrusions.
Preferably, described baffle plate tilts to elastic support rear end between vertebral body.
Further, between described vertebral body, elastic support rear end is provided with draw-in groove.
Preferably, between described uncovertebral joint fusion parts and vertebral body, the distance of elastic support front end is less than the distance that uncovertebral joint merges elastic support rear end between parts and vertebral body.
Preferably, described uncovertebral joint merges the material of parts is titanium alloy.Metallic titanium alloy material, may be used for imaging localization evaluation, does not affect patient's nuclear magnetic resonance check again.
Preferably, between described vertebral body, the material of elastic support is polyether-ether-ketone; Its elastic modelling quantity is close with cortical bone, and good biocompatibility has the intensity suitable with metal material and fatigue durability, can pass through x-ray, and MRI or CT examination can not produce artifact.
Further, the developing mark of X-ray opaque is provided with between described vertebral body in elastic support.
Preferably, described four trapezoidal rounding of angle.
Preferably, described baffle plate is titanium alloy sheet.
Beneficial effect of the present invention is as follows:
1, to take full advantage of human cervical spine both sides uncovertebral joint adjacent comparatively near in the present invention, and uncovertebral joint place closes on that soft tissue blood fortune is abundant waits cervical vertebra inherent advantage, and implantable bone creeping substitution is apart from short, and growth is fast, and merge fast, fusion rate is high.
2, bone-graft fusion is fast, and it is short therefore to wear the neck brace time, and patient experiences.
3, after discectomy, without the need to soleplate of polishing, easy and simple to handle, save operating time and economic cost.
4, uncovertebral joint fusion device does not destroy soleplate, and supporter adopts elastic support, and biomechanical property is good, and prosthese sinking risk reduces.
5, supporter designs for anatomical form, designs the form Design of soleplate up and down according to compatriots, makes the laminating of itself and upper and lower soleplate better.
6, supporting body surface has protruding pawl and circular protrusions, and implant can be prevented to be shifted.
7, supporter is polyetheretherketonematerials materials, and the imaging examination compatibility is good.
8, uncovertebral joint fusion place parts adopt network structure, more favourable blood fortune and Bone Ingrowth.
9, after uncovertebral joint fusion place parts, there is thin titanium alloy baffle plate in outside, can prevent bone grafting to grow into intervertebral foramina.

Fig. 2 is front view of the present invention;
Fig. 3 is rearview of the present invention;
In figure: between 1-vertebral body, elastic support, 2-uncovertebral joint merge parts, 3-baffle plate, 4-draw-in groove, 5-agnail, 6-circular protrusions.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.
As Fig. 1, Fig. 2, shown in Fig. 3, cervical vertebra uncovertebral joint fusion device disclosed by the invention, comprise uncovertebral joint and merge elastic support 1 between parts 2 and vertebral body, between vertebral body, elastic support 1 adopts anatomical form to design, to fit better with upper and lower soleplate, between vertebral body, the material of elastic support 1 adopts polyether-ether-ketone, the developing mark of X-ray opaque is provided with in elastic support 1 between vertebral body, between vertebral body, the cross section of elastic support 1 is similar trapezoidal, four rounding of angle, front end is small end, between vertebral body, elastic support 1 rear end is provided with draw-in groove 4, it is also longitudinally through that draw-in groove 4 is positioned at elastic support 1 rear end face between vertebral body, between vertebral body, the end face of elastic support and bottom surface are laid with protruding agnail 5 or circular protrusions 6, uncovertebral joint merges parts 2 two, be connected to the position of two waist lateral surface near front end of elastic support 1 between vertebral body, it is tubular network structure that uncovertebral joint merges parts 2, uncovertebral joint bone-graft fusion parts 2 are connected with baffle plate 3 away from the side of elastic support between vertebral body 1, and baffle plate 3 tilts to elastic support 1 rear end between vertebral body, uncovertebral joint merges parts 1, the material of baffle plate 3 all adopts titanium alloy.
