Abstract
The reamer comprises a cap (1) and radial rods (2) which are arranged uniformly on the inside edge of the cap. These radial rods (2), which are at least three in number, join up at the center of the cap and are integral. The reamer spindle comprises a shank (3) on which there is fixed a reamer spindle head (5) which is equipped with a bayonet with locking means for the securing of the reamer. The securing catches (10) of the bayonet are intended to receive the radial rods (2) of the reamer. The center (14) of the bayonet is preferably recessed so that the latter can receive the radial rods (2) of the reamer and can serve as a cavity for retention of the bone substance which is removed.
