Abstract

The surgical instrument set for the insertion of intervertebral endoprostheses, which consist of two stop plates and a sliding core to be arranged between them, is characterized in that it has spreading forceps (9) which have, at their front end on each spreading jaw (10, 11), an essentially U-shaped recess surrounding one stop plate on three sides and gripping the edge, the thickness of the spreading jaws (10, 11) in the spreading direction being essentially identical to the thickness of the stop plates.
