Accordingly, it is possible to prevent the convex- concave portion from being easily broken. In addition, since the broken pieces cannot easily occur, it is possible to prevent the broken pieces from damaging other organs.
  • the spine insert is formed by combining a plurality of divided parts, and the spine insert is formed by combining the divided parts s with a pin penetrating the divided parts. Accordingly, the spine insert having a desired size can be formed by using a material such as an animal bone which cannot be easily obtained in a desired size.
  • a through-hole penetrating the top surface and the bottom surface is formed. Accordingly, since a material for facilitating bonding the spine inset object with the vertebrae is inserted into the through-hole, the spine insert can be more speedily fixed.

Due to the aforementioned structure, it is possible to prevent the distal end from being broken and to prevent the broken distal end from damaging the human body.
  • the top surface is formed in a curved surface matching with a shape of a lower surface of a vertebra. That is, the top surface 100 is formed along the curved line 130 shown in FIG. 2.
  • the curved line 130 is the same as a curved line of the lower surface of the vertebrae which the spine insert is inserted between. Accordingly, the spine insert can be easily inserted.
  • the spine insert can be more strongly fixed after the insertion.

Therefore, the extracted animal bones are divided into a plurality of parts, and then, the divided parts are combined, so that the spine insert having a larger size than the original materials one can be obtained.
  • Each of the divided parts is provided with a pin-insert hole 600 that penetrates the divided part.
  • a pin is inserted into the pin-insert holes 600, so that the divided parts 11, 12, and 13 can be combined to form one spine insert 10.
  • the pin 700 is formed to have a diameter so that the pin is inserted into the pin-insert hole 600 by interference fit.

Abstract

La présente invention concerne un implant rachidien qui est inséré entre les vertèbres. L'implant rachidien est constitué d'une surface de dessus en contact avec une vertèbre supérieure ; d'une surface de dessous formée à l'opposé de la surface de dessus ; et de deux surfaces latérales réunissant la surface de dessus et la surface de dessous. La surface de dessus a l'aspect d'une surface convexe adaptée à la forme de la surface inférieure d'une vertèbre. L'implant rachidien peut donc être aisément inséré et plus fortement fixé à la colonne vertébrale après l'insertion.
