Abstract
The invention discloses a cervical vertebrae inter-vertebral disc prosthesis fixed between vertebral bodies. The prosthesis comprises an upper end plate (1), a lower end plate (3), and a sliding kernel (2) arranged between the upper end plate (1) and the lower end plate (3). The sliding kernel (2) is fixedly connected with the lower end plate (3) and provided with an upper protruding contact surface (21). The upper end plate (1) is provided with a lower sinking contact surface (11). The sliding kernel (2) can rotate in the lower contact surface (11) of the upper end plate (1) so that the cervical vertebrae inter-vertebral disc prosthesis can move freely between the vertebral bodies. According to the cervical vertebrae inter-vertebral disc prosthesis, after the artificial cervical vertebrae inter-vertebral disc is transplanted into the human body after an operation, a user can bend, stretch and laterally bend the cervical vertebra freely like a normal person, pressure on lesion sections can be reduced thoroughly, the vertebral column sequence is reconstructed, the biomechanics environment of a replacement stage is retained, and meanwhile regression of adjacent joints can be effectively prevented; the prosthesis has good biocompatibility with the human body.
Description
Technical field
The present invention relates to a kind of medical prosthesis, particularly relate to a kind of cervical intervertebral disc prosthesis replacing outstanding intervertebral disc.
Background technology
Along with China's rapid development of economy, industrial transformation, the change of people's job specification and living habit, the generalization that the sickness rate of cervical spondylosis also becomes, become younger, slight cervical spondylosis can cause neck shoulder to be ached, dizzy, limbs fatigue, if correct treatment not in time to cause cervical intervertebral disk generation pathological changes possibly, ruptured intervertebral disc is given prominence to towards periphery, stimulates peripheral nerve tissue to cause serious hyperosteogeny, finally cause pressuring nerve, cause cervical vertebra joint dislocation to make patient lose ability to act.
At present, method mainly anterior cervical decompression fusion and the vertebral body prosthesis art of state's this type of disease of internal therapy, but the problems such as the forfeiture of post-fusion Fusion levels mobility, Adjacent segment degeneration annoying spinal surgery doctor.Existing surgical product also exists the shortcoming such as operation process complexity, use duration, not easily fixing, Metal Contact face activeness difference easy to wear, postoperative.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, activity cervical intervertebral disc prosthesis easily.
For achieving the above object, the concrete technical scheme of a kind of cervical intervertebral disc prosthesis of the present invention is:
A kind of cervical intervertebral disc prosthesis, be fixed between vertebral body, the slip core comprising soleplate, lower soleplate and be arranged between soleplate and lower soleplate, slip core is fixedly connected with lower soleplate, slip core has protruding upper contact surface, upper soleplate has the lower contact surface of depression, slides to endorse and rotates in the lower contact surface of upper soleplate, so that intervertebral disk prosthesis can be freely movable between vertebral body.
The advantage of a kind of cervical intervertebral disc prosthesis of the present invention is:
1) after being applicable to intervertebral disk hernia disc removal, cervical spondylosis causes that neck and shoulder pain anterior decompression is postoperative, cervical vertebra degeneration instability companion kyphosis deformity, anterior cervical vertebrae shakiness decompression postcentrum are unstable and treatment after cervical spondylosis anterior cervical vertebrae multistage decompression;
2) vertebral body prosthesis art is adopted, postoperative artificial cervical intervertebral disc equally can carry out bending and stretching with normal person after implant into body, the freely movable cervical vertebra such as lateral bending, achieve the thorough decompression of lesion segment, rebuild vertebra sequence, remain the regression that displacement stage biomechanical environment also effectively can prevent adjacent joints simultaneously;
3) being fixed between cervical vertebral body of Absorbable organic halogens, has good biocompatibility with human body.

Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, further detailed description is done to a kind of cervical intervertebral disc prosthesis of the present invention.
As shown in Figures 1 to 7, it shows for cervical intervertebral disc prosthesis of the present invention, replace the intervertebral disc after intervertebral disk hernia, be fixed between vertebral body, the slip core 2 comprising soleplate 1, lower soleplate 3 and be arranged between soleplate 1 and lower soleplate 3, slip core 2 is fixedly connected with lower soleplate 3, slip core 2 has protruding upper contact surface 21, upper soleplate 1 has the lower contact surface 11 of depression, slip core 2 can rotate in the lower contact surface 11 of upper soleplate 1, so that intervertebral disk prosthesis can be freely movable between vertebral body.
Further, spherically, the shape of the lower contact surface 11 of upper soleplate 1 is the shape of mating with upper contact surface 21 to the upper contact surface 21 of slip core 2, and the radius of curvature of lower contact surface is identical with the radius of curvature of upper contact surface 21.In addition, lower contact surface is shiny surface.
Further, on the upper surface of lower soleplate 3, both sides are provided with steady pin 31, the both sides of slip core 2 are provided with notch 22, the width of the opening of notch 22 is a bit larger tham the width of steady pin 31, slip core 2 is by inserting steady pin 31 in notch to connect lower soleplate 3, wherein, the steady pin 31 of both sides is positioned on the horizontal line of maximum breadth of lower soleplate 3, and the notch of slip core 2 both sides is positioned on the horizontal line of maximum breadth of slip core.
Further, the upper surface of upper soleplate 1 and the lower surface of lower soleplate 3 are provided with protruding sawtooth 12,32, by inserting in vertebral body the sawtooth at intervertebral disk prosthesis two ends to make intervertebral disk prosthesis be fixed in human body.In addition, the surface of intervertebral disk prosthesis has plasma spray titanium valve layer, there is good biocompatibility with human body.
A kind of cervical intervertebral disc prosthesis of the present invention, after being applicable to intervertebral disk hernia disc removal, cervical spondylosis causes that neck and shoulder pain anterior decompression is postoperative, cervical vertebra degeneration instability companion kyphosis deformity, anterior cervical vertebrae shakiness decompression postcentrum are unstable and treatment after cervical spondylosis anterior cervical vertebrae multistage decompression; Adopt vertebral body prosthesis art, postoperative artificial cervical intervertebral disc equally can carry out bending and stretching with normal person after implant into body, the freely movable cervical vertebra such as lateral bending, achieve the thorough decompression of lesion segment, rebuild vertebra sequence, remain the regression that displacement stage biomechanical environment also effectively can prevent adjacent joints simultaneously; Being fixed between cervical vertebral body of Absorbable organic halogens, has good biocompatibility with human body.
