To insert a cage in the intervertebral disc space, the invention proposes an instrument set with a guide wire, with several dilators that can be pushed over the guide wire and over one another, with a working sleeve, and with a cage, in which the working sleeve is designed, in its distal area, in such a way that it allows its distal area to be fixed in the direction of its extent while permitting angular mobility or variable angular orientation of its proximal end. |
