Claim Text:
1. An operating method, comprising: providing an implanting apparatus and an intervertebral cage, wherein the implanting apparatus comprises a sleeve and an extension member, the extension member has a rod and a coupling column, the rod is screwed inside the sleeve, the coupling column is connected to one end of the rod and exposed outside the sleeve, an axial direction of the coupling column is substantially perpendicular to that of the rod, the intervertebral cage comprises a connecting portion, the connecting portion comprises a main portion and a protrusion, the main portion has at least one through hole, and the protrusion is protruded from the main portion into the through hole so as to form a first inner arc surface and a second inner arc surface; moving the implanting apparatus, so that the coupling column of the implanting apparatus is located at one side of the connecting portion of the intervertebral cage; rotating the implanting apparatus, so that one end of the coupling column is received in the through hole of the connecting portion and adjacent to the first inner arc surface; and rotating the rod with respect to the sleeve along a rotation direction, so that a distance between the sleeve and the coupling column is decreased to clamp the connecting portion between the coupling column and the sleeve, and the end of the coupling column presses against the first inner arc surface; wherein the intervertebral cage further comprises a body, the body has a lateral convex surface, a lateral concave surface, an inclined surface, a connecting surface and a fillet, the lateral convex surface, the fillet, the inclined surface, the lateral concave surface and the connecting surface are connected sequentially, the main portion is connected to the connecting surface of the body, and the operating method further comprises: percussing a terminal end of the implanting apparatus along a force applying direction, so that the intervertebral cage is moved along the force applying direction, wherein the force applying direction is a direction from a circle center of the first inner arc surface to a circle center of the fillet.
