INSTRUCTIONS: [Technical field of invention] In the human system, a kind of vertebral filling block, especially for ampoules, is used in the vertebral body of the human body. 3 as the ridge of the human intervertebral disc [previous technique] The spine in the human skeleton is composed of the majority of the nerves in the ventricle L ff, and the majority of the spine 2: the intervertebral disc is formed between the upper and lower vertebrae, and the intervertebral disc is the mechanical The subtle structure of the principle, which is shaped like a disc, has a nucleus pulpus in the center of the disk. It has a water ball composed of almost pure liquid. There is a phase: eve: plasticity can absorb the vertical pressure of the spine, and the nucleus is arranged intricately. The annulus fibrosus, strong (four) structure can maintain Zhao nuclear, palpitations 'so the intervertebral disc is the natural water pad of the human body, has considerable elasticity, can be used as a buffer between the upper and lower vertebrae; however, when any of the intervertebral discs in the sputum produce lesions or aging , will oppress the adjacent ridges = nerves cause pain 'caused the inconvenience of human action, and the phenomenon of intervertebral disc male heart or change wheat, most often occurs in the lumbar spine (lower ridge) or cervical vertebrae, for the above disc failure Many of the problems that have been caused are currently solved by target interbody fusion or intervertebral disc implantation. 'However, intervertebral fusion is performed. The original joint loses the effect of t, causing the upper and lower joints to bear the function of the original joint, thus causing the upper and lower joints of the spine joint to age or damage prematurely due to excessive use; in addition, the artificial intervertebral disc implanted in the intervertebral disc is usually not The elastic cushioning characteristics of the original human intervertebral disc, so that the joints after installation will lose all the slowness

When the invention is cracked, the top surface of the upper body and the bottom surface of the lower body 2 are attached to the adjacent vertebrae of the intervertebral disc area to be operated, and the bottom surface of the upper body and the lower surface of the lower body is protruded by the protruding cone. The tooth 12a (or the zigzag pattern 12b) allows the present invention to be fixed between the two vertebrae 61, 62; and the hydroxyapatite can be coated on the top surface of the upper body and the bottom surface of the lower body. The surface of the material is permeated through the hydroxyl group; 5 is attached to the adjacent vertebrae to achieve the purpose of biological fixation; in addition, the bone removed in the hand is filled into the bone pits 13 and 23 of the upper and lower cushions. In order to form a bone column in the bone graft pits for a period of time, and to precisely design the bone groove pits (4), the annular groove portions 13a, 23a are designed such that the bone column hyperplasia bones can be engaged in the #ring groove In the department (1), the upper and lower vertebrae 61 and 62 are respectively fixed between the upper and lower vertebrae 61 and 62, respectively, to achieve the purpose of gain stability, and prevent the spine from being excessively deduced by excessive forward tilting. It can also avoid the displacement or loosening of the two from the present invention, resulting in intervertebral collapse and instability of the spine. After the invention is installed, the original height of the collapsed intervertebral disc can be reconstructed, and the natural activity of the intervertebral disc at the treatment site can be established and the movement of the intervertebral disc can be controlled by (4) or the nerve root, and the elastic body can be elastically deformed. & 1 '^The force of the bomb, the secluded *volume to effectively share the spine in all directions, this & vertebrae fractures for when the body jumps, jumps high or 22, when the waist suddenly loads heavy objects 'The elastomer also immediately produces the immortal pressure of the morning slave, the cushion cushioning effect. The invention has less of the following characteristics: 7212ΡΙΛ 9 200916071, and has the elastic cushioning characteristics of the original human intervertebral disc, and the operational efficiency of the post-anal is almost the same as that of the positive f intervertebral disc, so the spine is obtained. The other normal intervertebral discs work closely together to maintain the performance provided by the upper and lower vertebrae = the original joints, to avoid damage to the upper and lower sections, and to prevent aging. With a sporting pattern that can flex, stretch, bend and twist, the spine's movements are unrestricted. 4. The invention can be integrated with the growth of bone tissue, so that it not only has the characteristics of stable connection, but also further prevents the spine from excessively tilting (buckling, stretching, lateral green) of the spine to avoid pathological changes. Excessive opening of the upper and lower vertebrae = wedge type can reduce the chance and frequency of sliding friction between the joint surfaces, thus greatly reducing the wear of the joint surface and increasing the service life of the artificial intervertebral disc.
