Abstract

The invention provides an intervertebral disc prosthesis. The intervertebral disc prosthesis comprises an upper intercalated disc, a lower intercalated disc and a nucleus pulposus body arranged between the upper intercalated disc and the lower intercalated disc, and the part, used for being matched with a bone, of the upper intercalated disc and / or the lower intercalated disc is of a microcellular structure. By the application of the technical scheme, through the microcellular structure, the stability of the intervertebral disc prosthesis fixed to bone substances in the early period can be enhanced, and bone substance growth can be promoted; after the bone substances grow into the microcellular structure in the long period, long-term stable fixation can be realized, therefore, when the intervertebral disc prosthesis is replaced, the bone substances are processed a little, the situation that a vertebral end plate collapses is avoided, combination of the intervertebral disc prosthesis and the bone substances can be realized, and connection between the intervertebral disc prosthesis and the bone substances is firmer.

Description

Technical field [0001] The invention relates to the field of artificial prostheses, in particular to an intervertebral disc prosthesis. Background technique [0002] Artificial cervical disc replacement is an advanced prosthesis replacement procedure that replaces the "anterior cervical decompression and bone graft fusion" that has been used for nearly 50 years, and overcomes the latter's shortcomings and major complications. Traditional anterior cervical decompression and bone graft fusion has always been a means to treat myelopathy and radiculopathy caused by cervical intervertebral disc herniation, but this traditional operation has great limitations: the operation changes the normal biomechanics of the cervical spine , Resulting in the loss of motor function of the surgical segment, accelerated degeneration of adjacent segments; bone grafting does not heal, forming false joints; bed rest for a long time after surgery, the recovery period also needs to wear the neck circumfere...
