An insertion instrument for a multi-part intervertebral endoprosthesis includes two closure plates and a sliding core arranged between these, said insertion instrument having a handgrip part, gripping members which hold the closure plates between them, and a force-receiving part for applying an insertion force to the intervertebral endoprosthesis, the gripping members being guided movably toward and away from one another via a hinge and being able to be tensioned against the intervertebral endoprosthesis, projections pointing in the tensioning direction or recesses for holding the intevertebral endoprosthesis with form-fit being provided on the gripping members, and a block guided in the longitudinal axis direction and with an abutment surface being provided which can be moved by means of an actuating device so as to bear on the intervertebral endoprosthesis and, in its forward position, secures the intevertebral endoprosthesis against the projections or recesses. |
