Description

The anterior cervical vertebrae Invasive lumbar fusion device
Technical field
The present invention relates to a kind of intervertebral disc of cervical vertebra implant, specifically according to human cervical spine physiological characteristics and the anterior cervical vertebrae Invasive lumbar fusion device of dissecting structural design.
Background technology
Lower intervertebral disc of cervical vertebra degeneration and wound often can cause intervertebral disk hernia and cause that limbs pain and other nervous symptoms, its therapeutic method of surgery adopt anterior decompression, extract the modes such as intervertebral disc, intervertebral fusion, fixing operation sections.Goldstandard need to be got three cortical bones from patient's ilium, then cortical bone is implanted intervertebral, and outer fixing.But tend in the follow-up process to occur that plant bone mass absorbs, subsides, deviates from, loose shift is outstanding or the major defect of charging into canalis spinalis or intervertebral foramina, thereby cause intervertebral space, Neuroforamen height and cervical vertebrae physiological sequence to keep deficiency, cause not merging, even the formation of pseudarthrosis.And higher for bone district complication, comprise and get bone district pain, infection, fracture of wing of ilium etc.
Cervical vertebral fusion cage can replace three cortical bones, section's implantable bone tissue within it, can provide support and frame structure for intervertebral firmly merges, recover intervertebral height, rebuild or maintenance cervical vertebrae physiological sequence, cervical vertebra mechanical balance state is kept in the decompression of neuromechanism, correct the cervical spine degeneration deformity that has existed, improve Quality of Life.
Invasive lumbar fusion device uses clinically widely at present, and all kinds are arranged on the market.Be ZL02276208.6 such as the patent No., name is called in the utility model patent of Invasive lumbar fusion device, adopts DL-LACTIC ACID, poly (l-lactic acid) and copolymer to make; But this utility model patent needs to knock the Invasive lumbar fusion device installing apparatus in implanting the intervertebral process, because fusion device is subject to the frictional force between outside percussion power and the upper hypocentrum, the in addition intensity restriction of this material own, very fragile fusion device, the risk of increase operative failure.
Notification number be CN201701334U, the name be called in the utility model patent of cervical vertebral fusion cage, what adopt is the material of titanium alloy, but owing to the titanium alloy material elastic modelling quantity produces stress shielding much larger than human bone, according to the woff law, the phenomenon that may form pseudarthrosis or not merge; And pseudo-shadow can appear when doing x-ray, CT examination, affect the observation of postoperative.
Summary of the invention
The object of the invention is to overcome the shortcomings and deficiencies of prior art, provides a kind of operation technique simple, meets the human cervical spine physiological structure, recover intervertebral height, recover the cervical vertebrae physiological lordosis, and can provide the initial stage stable, promote the anterior cervical vertebrae Invasive lumbar fusion device of intervertebral fusion.
In order to achieve the above object, the present invention is by the following technical solutions: the anterior cervical vertebrae Invasive lumbar fusion device, and comprise main body and be arranged on development pin on the main body, described main body is the tetrahedron of hollow, the cross section of tetrahedron periphery is trapezoidal, and the cross section in week is square or rectangle in the hollow; Described main body comprises antetheca, rear wall, left side wall and right side wall, and antetheca is connected with rear wall by left side wall, right side wall.
The outside of described left side wall and right side wall is the uneven opposite side of described main body trapezoidal cross-section, is symmetrical structure.
Described left side wall, right side wall upper and lower surface are equipped with pawl.
The upper surface of described main body is curved, and lower surface is horizontal.Upper surface arc peak in described main body is provided with holdfast, is provided with lower holdfast at the lower surface of described main body, lower holdfast be positioned at holdfast under.
The curved outer gibbosity of described antetheca outer surface.The outer surface of described rear wall is perpendicular to the lower surface of main body.
The upper surface of described antetheca, rear wall, lower surface all have the arc groove vertical with the human body coronalplane.
Compared with prior art, advantage of the present invention and beneficial effect are:
1, the shape of main body meets the anatomic form of normal human's intervertebral disc of cervical vertebra very much, when guaranteeing that safety is implanted, main body can with cervical vertebra terminal plate of vertebral body close contact under pressurized state up and down, be that good condition is created in the bone fusion.
The cross section in week is square or rectangle in the 2 main body hollows, and the contact area with try one's best increase and terminal plate of vertebral body increases the bone grafting amount, accelerates to merge.
3, the arc groove on body front wall and the rear wall, the pawl of left and right sides sidewall has increased the frictional force between main body and cervical vertebral body soleplate, prevents main body front and back in vertebral body, horizontally slips, and reaches stable cervical vertebra, promotes the purpose that merges.
4, upper holdfast and lower holdfast all are embedded in the vertebral body, are arranged in the columnar region of vertebral body, are fixed in the cortical bone, are difficult for becoming flexible, and good fixing effect increases primary stability and is beneficial to fusion.
5, material of main part is polyether-ether-ketone, and is similar to the sclerotin elastic modelling quantity, biocompatibility safety, and suitable human body is implanted, and can not produce pseudo-shadow under the x line is taken, and does not affect clinical follow.
6, the development needle material is medical TC4, is located in the fusion device, and not only human body is implanted safety, and is convenient to imaging observation.
