Tool for creating drill holes in bones or removing cylindrical drill cores from bones in the human body

摘要

The tool (1) has a body (2) connected with a tool support (4) of a drive device. The body has a recess (5) in which a projection (10) is received. The projection projects from an interior surface of the body. A tongue (15) is spaced axially from the recess and points towards an outer end of the body. The tongue enters into an opening of a wall in the support, during pushing of the body in the support directly before impinging of the body in a stopper (7). The stopper locks the body in the support against axial displacement.
