INSTRUCTIONS: [Technical Field] The present invention relates to a movable intervertebral filling block device, which can be implanted into a vertebrae, with an open intervertebral filling block and vertebrae The movable intervertebral filling block device is fused in that the other sliding piece is in sliding contact with the filling block to maintain the intervertebral function. [Previous technique] The traditional intervertebral artificial cage (cage, spacer) is only a simple one. When the disc collapses or shrinks, the implant replaces the original vertebral disc branch to restore the intervertebral height and the natural curve of the spine. A type of eight-filled block device. The artificial intervertebral block device does not have any artificial movable joint function, but is only a single entity, and is completely unable to provide or restore the original mobility of the natural intervertebral disc. Another type of artificial intervertebral disc that can replace the natural intervertebral disc is mostly a one-piece, one-piece two-piece nesting assembly, which is a solid body upper and lower receiving seat, or a sandwich of different materials in the middle interlayer. Through the locking mechanism of different designs such as spikes, serrations, and rough faces, it is attempted to be tightly coupled between the upper and lower vertebrae after excavating the natural intervertebral disc. However, the conventional artificial intervertebral disc is only a single-passing engagement or a rough surface that is engaged with the intervertebral vertebrae. In the case where the upper and lower vertebrae are still movable, it is very easy to be unfixed and cause a pull out problem. Therefore, how to combine the advantages of both, avoid or simply and effectively solve the above two shortcomings, with the mobility of natural intervertebral disc joints, intervertebral height 5 200938155

However, due to the natural movement ability of the human body, especially when the intervertebral 22 of the replacement artificial intervertebral disc is still active 'The angle of the 22 motion of the intervertebral body, the strength, the square 〃 / 疋 ° and the traditional artificial intervertebral disc 30 can be completely conceived, so there is the danger of hiding the traditional artificial intervertebral disc 30 will cause the phenomenon of slippage. In the present invention, a movable intervertebral filling block device 40, which comprises an intervertebral filling block 41 which can be implanted between the upper and lower vertebrae 20 and 21, and has an intervertebral filling block 41 The wall 4 11 defines an opening accommodating space 412, and a plurality of spikes are protruded from the bottom surface of the surrounding wall 411. The intervertebral filling block space 412 can be filled with medical materials, such as artificial bones, and the like. The opening 4 1 3 is implanted to the lower vertebra 22, down to the lower vertebra 2 1 the surface is in contact, the opening 213 is opposite to the other surrounding wall surface 414, and can be in contact with the upper vertebra 20, and the height of the intervertebral 22 is restored and the medical material in the working chamber 412 is The vertebral body can be fused with the lower vertebra 2 to stabilize the fixation of the intervertebral filler block 41. As shown in Fig. 3b, the movable intervertebral filling block device 4 further includes a sliding piece 42. The sliding piece 42 can be covered by the movable portion. The other surface of the intervertebral filling block and the sheet 42 protrude upwardly to form a plurality of tips which are engaged with the surface of the vertebra 20 above the iliac crest, forming a slidable contact between the intervertebral filling block 41 and the sliding piece a. Moreover, since the other surface 414 of the intervertebral filling block 41 is disposed as a convex ball fox, the sliding piece 42 is relatively concavely formed as a concave ball 421, and the two mating filling blocks 41 and the sliding piece 42_(four) wire are not Binocular: slidable contact 'maintains the mobility of the 22 joints of the intervertebral, rather than merging them into a body. In Fig. 4, the movable intervertebral filling block is provided with a fully convex intervertebral filling block 41, = having the above - The exception to the preferred implementation of the wire strike 1 per V month rotor 42. The preferred embodiment is a small degree of sliding - a bump intervertebral filling block 43 200938155 and a matching one of the sliding pieces 44. The convex intervertebral filling block 43 has a flat disc-shaped bottom 43 丨, and a spherical convex shape is convex upward in the center. Point 432, and forming an open receiving space for filling a medical material, the bump intervertebral filling block 43 is also implanted downwardly between the vertebrae 20, 21 with the opening 434, so that the medical material can help The intervertebral filling block 43 can be fused and stabilized, and the height of the spherical bump 432 of the intervertebral filling block 43 can restore the natural height, the area and the space of the intervertebral space 22. & ❹ ... and the sliding piece 44 cooperates with the convex intervertebral filling block 43 spherical convex point 432, concavely-concave ball arc 441, and one of the peripheral planes 442, the convex intervertebral filling block 43 and the sliding The sheets 44 can be matched, and because the bottom portion 43 1 and the flat surface 442 of the flat plate are restrained by the top, only a limited sliding motion can be performed. In Fig. 5, the intervertebral filling block 41 and the sliding piece 42 are further extended with perforated fixed side pieces 415, 422, which can be passed through a screw 5, and the nail is inserted into the upper and lower vertebrae 2, 2 i 'This makes the movable intervertebral block device less prone to slippage when implanted into the intervertebral space 22.
