Intervertebral fusion implant

A system comprising an intervertebral fusion implant for the fusion of two vertebrae, the intervertebral fusion implant comprising an upper bearing body for placing on a lower end-plate of a vertebra, a lower bearing body for placing on an upper end-plate of an opposite vertebra, and a central piece arranged between the bearing bodies, and forceps with a mouth having first and second jaw elements, wherein the central piece comprises a claw coupling which, in a coupling position, couples the two bearing bodies in a rotationally fixed manner to each other, wherein, in an open position of the claw coupling, the bearing bodies are freely movable relative to each other, wherein the claw coupling is automatically actuatable and comprises an actuating member comprising a plastic blocking body which, in its initial position, holds the claw coupling open and, under a load transferred from one vertebra to the other vertebra, is slowly deformable until it reaches a final coupling position in which the claw coupling is closed, and wherein the jaw elements are configured for a positionally offset arrangement of protrusions on the upper and lower bearing bodies such that the protrusions of the upper bearing body are arranged next to the protrusions of the lower bearing body.
