摘要：
The invention relates to a cutting broaching tool (1) for intraoperatively obtaining bone material from a patient, comprising a main part (3) which rotates about a rotational axis (2) for securing on a rotating tool support and comprising at least one blade (4) which is rigidly connected to the main part (3). The aim of the invention is to prevent the tissue from reacting when using the broaching tool and thus prevent an increased risk of infection, to prevent a thermal load on the bone, to receive the bone material in the interior of the broaching tool, and to discharge the bone material to an external device. This is achieved in that the main part (3) has a cylindrical shape, is hollow, and surrounds a first cavity (5). The blade (4) or all the blades (4) are formed integrally with the main part (3), extend in the direction of the rotational axis (2) of the main part (3) at a distance from an end face (6) of the main part (3), and surround a second cavity (7). The first cavity (5) is connected to the second cavity (7) in order to receive and transport the cut bone material, and the broaching tool (1) is made of a sintered ceramic material.
