Forceps for inserting intervertebral device
First Claim
1. A surgical forceps for applying pressure against a vertebral body, said forceps having a back portion and a front portion including a front end, the front portion being formed as first and second spreading jaws that are substantially parallel when in a spread position, each spreading jaw having a substantially U-shaped recess having an open portion directed towards front end of the forceps, each U-shaped recess being defined in a plane substantially parallel to the other jaw and perpendicular to the spreading direction and including an inner wall having a groove arranged in a plane substantially perpendicular to the spreading direction.

Abstract
A spreading forceps (9) which has, at its 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 (FIG. 1). The spreading forceps is useful for the insertion of intervertebral endoprostheses.
