Description
Technical field
The utility model belongs to a kind of Invasive lumbar fusion device, and in particular to a kind of cervical vertebra intervertebral with Bone Ingrowth micropore melts
Clutch.
Background technique
Intervertebral disc of cervical vertebra protrusion is one of spinal surgery common disease, to the prominent effective ways treated of intervertebral disc of cervical vertebra
It is to carry out intervertebral fusion operation, i.e., removes the Intervertebral disk displacement of lesion, is then put into and interverbebral disc in removed vertebral disc portion
The consistent cervical vertebral fusion cage of shape makes cervical vertebra reach instant stabilization, promotes fusion, rebuilds and maintain the life of intervertebral height and cervical vertebra
Manage radian.
Cervical vertebral fusion cage common at present does not have the micropore on supporting surface, so bone melts on the coronal-plane of cervical vertebral body
The area of conjunction is smaller, only the integration region of bone grafting window upper and lower ends, and Invasive lumbar fusion device will be chronically implanted human body, in centrum
Under the action of growth, the bone uptake in bone grafting window region is too fast, easy that bottom support surface on fusion device is hanging, and fusion device is caused to support
The support force in face is inadequate, and load-bearing is transferred to the fused bone in the region of only bone grafting window, with the physiological activity of human body, corresponding circle of sensation
The pressure of domain bone can increase with it, and cause the fracture of intervertebral fusion bone, cause the centrum of cervical vertebra unstable.
Utility model content
The utility model is, the bone in bone grafting window region existing in the prior art under the action of centrum growth in order to overcome
Grow it is too fast, be easy bottom support surface on fusion device is hanging, cause the support force of fusion device supporting surface inadequate, load-bearing is transferred to only
The fused bone in the region of some bone grafting windows, with the physiological activity of human body, the pressure of integration region bone can be increased with it, and cause vertebra
Between fused bone fracture, the disadvantage for causing the centrum of cervical vertebra unstable and propose, the purpose is to provide a kind of to have Bone Ingrowth
The cervical vertebra Invasive lumbar fusion device of micropore.
The technical solution of the utility model is:
A kind of cervical vertebra Invasive lumbar fusion device with Bone Ingrowth micropore, including by preceding wall, left wall, rear wall and right device
Wall is sequentially connected the ontology of the fan-shaped tetrahedral structure in the cross section surrounded, and the hollow space surrounded forms bone grafting window；This
Body upper surface forms circle trapezoidal groove wide at the top and narrow at the bottom, and groove slot bottom forms multiple Bone Ingrowth micropores being vertically arranged, on a left side
Wall and rear wall are respectively formed on location hole, form threaded hole in the middle part of rear wall；The left wall and rear wall upper and lower end face
Edge is respectively formed sawtooth；The intersection and preceding wall middle line of the left wall and rear wall intersection, rear wall and right wall
The wall at place is internally provided with development needle.
The preceding wall height is arranged lower than rear wall, left wall and rear wall in mirror symmetry.
Plane of the opening direction of the location hole perpendicular to left wall or rear wall where it.
The opening direction of the threaded hole is perpendicular to the rear wall plane where it.
The Bone Ingrowth micropore is the through-hole through each wall upper and lower end face.
The development needle of the intersection of the development needle of the left wall and rear wall intersection and rear wall and right wall is arranged
In on the position of the same cornerwise upper and lower side of rear wall.
The beneficial effects of the utility model are:
The utility model uses PEEK(polyether-ether-ketone) material, designing has bone grafting window and development needle, while on the support surface
Increase the micropore for Bone Ingrowth.PEEK(polyether-ether-ketone) material can have an X-rayed under light under X, and bone grafting window is merged with bone grafting, is shown
Shadow needle is used under X-ray show the implantation position of fusion device, the Bone Ingrowth micropore on the supporting surface of fusion device, which is through whole
A fusion device thickness through-hole can increase in the artificial self-bone grafting Bone Ingrowth of Bone Ingrowth micropore implantation and micropore same diameter in art
Bony union on the support surface.Clinically, have and increase the area of intervertebral fusion, enhancing interbody fusion postcentrum is stablized
The effect of property.

Specific embodiment
With reference to the accompanying drawings of the specification and the embodiment cervical vertebra intervertebral with Bone Ingrowth micropore a kind of to the utility model
Fusion device is described in detail:
As shown in Fig. 1 ~ 4, a kind of cervical vertebra Invasive lumbar fusion device with Bone Ingrowth micropore, including by preceding wall 1, left wall
2, rear wall 3 and right wall 4 are sequentially connected the ontology 5 of the fan-shaped tetrahedral structure in the cross section surrounded, and what is surrounded is hollow
Space forms bone grafting window；5 upper surface of ontology forms a circle trapezoidal groove 6 wide at the top and narrow at the bottom, and 6 slot bottom of groove is formed multiple to be set vertically
The Bone Ingrowth micropore 7 set is respectively formed on location hole 8 in left wall 2 and rear wall 3, and threaded hole 9 is formed in the middle part of rear wall 3；
The left wall 2 and 3 upper and lower end face edge of rear wall are respectively formed sawtooth 10；
