Embodiment 1

[0042] An implant for spinal decompression, the implant 10 for spinal decompression includes an upper implant 1 and a lower implant 6, the lower part of the upper implant 1 is provided with an upper insertion part 2 for inserting into the intervertebral space The upper part of the lower implant body 6 is provided with a lower insertion part 7 for inserting into the intervertebral space, the upper insertion part 2 and the lower insertion part 7 can be inserted into the intervertebral space at the same time, and the inner plant for decompression of the spine also includes a lower insertion part that can make the upper implant Body 1 and lower plant body 6 separated stretching components, such as figure 1 and figure 2 shown.

[0043]The upper insertion part 2 and the lower insertion part 7 can be inserted into the gap between the two vertebrae at the same time, and then the distraction assembly will separate the upper implant 1 and the lower implant 6 from each other along the ...

Embodiment 2

[0052] This embodiment is an improvement on Embodiment 1. In this embodiment, the spreading assembly includes upper racks 12 located on the left and right sides of the upper implant 1 and lower racks located on the left and right sides of the lower implant 6 13, such as Image 6 As shown, the upper rack 12 is fixedly connected with the upper implant 1 , and the lower rack 13 is fixedly connected with the lower implant 6 . The sawtooth structure of the upper rack 12 on the left is engaged with the sawtooth structure of the lower rack 13 on the left, the sawtooth structure of the upper rack 12 on the right is engaged with the sawtooth structure of the lower rack 13 on the right, and the upper teeth The sleeve 14 that prevents the separation of the upper rack 12 and the lower rack 13 is set outside the bar 12 and the lower rack 13. This expansion assembly can only separate the upper implant 1 and the lower implant 6 in one direction without making the upper implant 1 and the lowe...

Abstract

The invention provides an implant for spinal decompression, an intervertebral implanted bone fusion cage and an artificial intervertebral disc. The implant (10) for spinal decompression comprises an upper implant body (1) and a lower implant body (6), the lower portion of the upper implant body (1) is provided with an upper inserting portion (2) used for being inserted into a spinal clearance, and the lower implant body (6) serves as a mirror image of the upper implant body (1). The upper implant body and the lower implant body are simultaneously inserted into the intervertebral clearance and fixed through screws to form an upper rail and a lower rail. The implant further comprises a distraction assembly which can separate the upper implant body and the lower implant body, axial distraction and decompression can be regulated, precise clearance regulation is achieved, a vertebral distraction instrument is replaced, the lesion narrow clearance is enlarged, implanting, decompressing, precise fusion cage (or artificial intervertebral disc) feeding along the rails are integrated into one step, a three-dimensional stable mechanical module is formed together with a spinal lesion segment, and complications such as displacement, subsidence and dislocation of the fusion cage (or the artificial interertebral disc) are thoroughly eliminated.

Description

technical field [0001] The invention relates to a medical device, in particular to an internal plant for spinal decompression, an intervertebral bone fusion device, and an artificial intervertebral disc. Background technique [0002] Anterior cervical intervertebral space decompression and bone graft fusion are classic operations that have gone through more than half a century, and are also the only effective methods to solve cervical spondylotic degeneration and spinal cord compression cervical spondylotic myelopathy. The key to surgery is complete decompression of the spinal cord. For the remaining intervertebral space after decompression, the degenerated intervertebral disc tissue is removed and there is a defect, which requires bone grafting and fusion to rebuild and stabilize it. In addition to the traditional autologous ilium three-sided cortical bone filling bone graft, in recent years, various new technologies have been applied one after another. In view of complic...
