Abstract

The invention discloses an artificial intervertebral disk. The intervertebral disk is designed to consist of three parts: an upper base, a nucleus pulposus and a lower base, wherein the upper base is matched with the spherical convex face of the top face of the nucleus pulposus through the concave spherical face on the bottom face of the upper base; and the lower base is connected with sliding rails on the bottom face of the nucleus pulposus through a dovetail groove on the top face of the lower base. When the spine bends and straightens, the upper base and the nucleus pulposus perform spherical-face arc-shaped sliding through the spherical structure, and the lower base and the nucleus pulposus perform back and forth sliding in the dovetail groove on the lower base through the sliding rails. Due to the design, the movement of the artificial intervertebral disk is close to that of the intervertebral disk of human body, so that the regression possibility of adjacent intervertebral disks is lowered.

Description

A kind of artificial intervertebral disk
Technical field
The present invention relates to medical field, particularly the spinal column artificial intervertebral disk.
Background technology
The spinal column artificial intervertebral disk, being applied at present clinical has a variety ofly, but its motor pattern differs greatly with actual human intervertebral disc motor pattern, may quicken the adjacent discs regression behind its implant into body.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of promptly with the more close artificial intervertebral disk of actual intervertebral disc motion pattern.
Design concept of the present invention is that artificial intervertebral disk not only can be done the sphere arcuate movement, also has simultaneously to seesaw, and be the compound pattern of multiple motion mode thereby make the artificial intervertebral disk motion near the motion of human intervertebral disc.
Based on above design, the present invention adopts following technical scheme: a kind of artificial intervertebral disk comprises vertebral pulp, upper bed-plate and three parts of lower bottom base.The vertebral pulp top contacts by the spill sphere of convex spherical with the upper bed-plate bottom, and the vertebral pulp bottom is connected by the dovetail groove of slide rail with the lower bottom base top.And the soleplate face surface of the top of upper bed-plate and lower bottom base bottom is pressed with the titanium silk and bone is induced coating, be used for Up/down base and intervertebral space up and down soleplate contact fusion, when spinal column bent and stretched, not only upper bed-plate and vertebral pulp were made the sphere arcuate movement, simultaneously, vertebral pulp and lower bottom base carry out the front and back slip.This kind design makes the artificial intervertebral disk motion relatively near the human intervertebral disc motor pattern, thereby has reduced adjacent discs regression probability.
Description of drawings
Fig. 1 is the structure chart of a kind of artificial intervertebral disk of the present invention.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
A kind of artificial intervertebral disk shown in Figure 1 comprises a upper bed-plate 1, vertebral pulp part 2, lower bottom base 3 and two bayonet locks 8,9.
Mounting means of the present invention is as follows: the slide rail 4 of vertebral pulp 2 bottom surfaces is inserted in the dovetail groove 5 of lower bottom base 3 end faces, bayonet lock 8,9 is inserted respectively in the jack 6,7 of dovetail groove 5 open ends, the spill sphere of upper bed-plate 1 bottom surface is cooperated with the spherical concave surface of vertebral pulp 2 end faces, embed in the intervertebral space of spinal column, upper bed-plate 1 end face contacts fusion by surperficial titanium silk coating with intervertebral space top soleplate, lower bottom base 3 underrun titanium silk coatings contact fusion with intervertebral space bottom soleplate, and dovetail groove 5 open ends are to the vertebral body front simultaneously.
Its operation principle: when flexion of vertebral column, upper bed-plate 1 slides with the sphere arc that vertebral pulp 2 is done forward by spherical structure, simultaneously the guide rail 4 of vertebral pulp 2 is done to front slide in lower bottom base 3 dovetail grooves, thus when causing upper bed-plate 1 to make sphere circular arc is moved forward with respect to lower bottom base 3 also with motion to front slide.When stretching behind the spinal column, upper bed-plate 1 slides with the sphere arc that vertebral pulp 2 is done backward by spherical structure, simultaneously the guide rail 4 of vertebral pulp 2 slides backward in lower bottom base 3 dovetail grooves, thus when causing upper bed-plate 1 to make sphere circular arc is moved backward with respect to lower bottom base 3 also with the motion that slides backward.

Claims (3)
