The present invention concerns an instrumentation device for inserting or fitting an intervertebral disc prosthesis, characterized in that it comprises an insertion guide (9,93) including an internal channel (90) presenting an end in which certain edges, or support edges (910, 920, 931, 932), protrude from the others along the longitudinal axis (d9) of the channel so as to be able to take the place of distraction tools of a known type previously used to increase the opening of the disc space, this channel (90) presenting an internal section capable of surrounding these same distraction tools while they maintain this opening, then allowing their extraction through said channel while said support edges (910, 920, 931, 932), for their part, preserve the opening of the disc space by replacing the distraction tools, then receiving and guiding the prosthesis (P) for insertion in this disc space. |
