  • Patent number: 9522071
    Abstract: An implanting apparatus and an operating method thereof are provided. An implanting apparatus used for implanting an intervertebral cage into a location between two adjacent vertebral bodies, wherein the implanting apparatus comprises a sleeve and an extension member. The extension member has a rod and a coupling column, wherein the rod is screwed inside the sleeve, the coupling column is connected to one end of the rod and exposed outside the sleeve, and the axial direction of the coupling column is substantially perpendicular to that of the rod. When one end of the coupling column is disposed on an inner arc surface of a connecting portion of the intervertebral cage and the rod is rotated with respect to the sleeve, the distance between the coupling column and the sleeve is decreased so as to clamp the connecting portion of the intervertebral cage between the coupling column and the sleeve.

  • Patent number: 8784493
    Abstract: An intervertebral cage, an implanting apparatus and an operating method thereof are provided. The intervertebral cage for being implanted between two adjacent vertebral bodies includes a body and a connecting portion. The body has a lateral convex surface, an inclined surface, a lateral concave surface and a connecting surface connected sequentially. The connecting portion includes a main portion and a protrusion. The main portion connected to the connecting surface has a through hole. The protrusion is protruded from the main portion into the through hole to form first and second inner arc surfaces. The maximum width of the intervertebral cage is a distance between first and second lines. The first and second lines are substantially parallel to a tangent line of the lateral convex surface and the first line, respectively. The distance between the inclined surface and the first line decreases gradually along a direction away from the connecting portion.
