Technical field
This utility model relates to orthopaedics medical instruments field, specifically a kind of artificial intervertebral disk.
Background technology
Lumbar intervertebral disc is made up of outside fiber ring, internal vertebral pulp and upper and lower terminal plate of vertebral body, is human body maximum depletion of blood fortune group
Knitting, its major function is load, the activeness ensureing vertebral body and stability etc. between transmission vertebral body.Along with the growth at people's age,
The minimizing of lumbar nucleus pulposus moisture will cause its degeneration.The lumbar intervertebral disc of degeneration, it transmits load, guarantee
The function of vertebral body activeness and stability changes, thus causes lumbar intervertebral disc physiological function to be affected.
The Therapeutic Method of the existing lumbar intervertebral disc for degeneration is controlled for bed, medicine, traction, physical therapy etc. are conservative
Treat.When expectant treatment is invalid or patient with severe symptoms must carry out operative treatment, and operative treatment is divided into fusion and replacement.If used
Fusion destroys normal disc anatomical structure, mobility reduces, neighbouring section is got involved；And use replacement to rebuild dissection
Structure, recovery physiological function.Replacement is by removing pathological interspinal dish tissue implantable artificial lumbar intervertebral disc, thus releases nerve root
Mechanical pressure, minimizing autoimmune source and the anti-inflammatory agent of degeneration intervertebral disc induction.Thus, artificial lumbar disc replacement is
Preferably lumbar intervertebral disc degeneration iatrotechnics formula.
Abroad, for existing hundreds of kind of the prosthetic designs of artificial intervertebral disc, existing prosthese puts into clinical operation should
With.Can design also in blank by the domestic artificial lumbar disc for compatriots' anatomical structure.Owing to ethnic group has diversity, different
The lumbar intervertebral disc of ethnic group necessarily there is also diversity.The present invention is based on China's Chinese Lumbar Vertebrae intercalated disc structural anatomical parameter designing one
Money is suitable for the artificial lumbar disc of compatriots' anatomical structure.
Summary of the invention
In view of this, this utility model aims to provide a kind of artificial intervertebral disk, this artificial intervertebral disk can well with waist
Vertebral body coordinates, and makes interspace of lumbar vertebrae recover normal, and without repelling and foreign body reaction, and the physiology that can basically reach lumbar intervertebral disc in normal adult is lived
Dynamic function.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that a kind of artificial intervertebral disk, including one
Chassis, described chassis is rotationally connected one and takes over a business, the edge on described chassis be provided with one after fixture, described rear fixture interior
Side is provided with a groove, described in the edge taken over a business be positioned at groove, described chassis is provided with two stopper slots, and two stopper slots are positioned at
The both sides of rear fixture, described in the bottom taken over a business be provided with two limited posts, two limited posts lay respectively in two stopper slots.
Further, described chassis is provided with a chute, and described chute is arranged concentrically with chassis.
Further, described in the bottom taken over a business be provided with a slide block, described slide block with take over a business to be arranged concentrically, described slide block is being slided
In groove.
Further, described chassis is equipped with fixing hole on taking over a business.
Further, the center on described chassis is provided with a bearing, described in the bottom centre taken over a business be provided with one and fix post, described
Fixing post is fixed on the outer ring of bearing.
Further, the material taken over a business described in is pottery.
Further, the material on chassis is pottery.
Relative to prior art, this utility model has the advantage that
This utility model artificial intervertebral disk, this artificial intervertebral disk can coordinate with lumbar vertebral body well, makes interspace of lumbar vertebrae extensive
Multiple normal, without repelling and foreign body reaction, and the physiological activity function of lumbar intervertebral disc in normal adult can be basically reached.
