Abstract: A device for driving a wire pin, and in particular a Kirschner wire, into bone material, comprising a propelling device that acts upon the wire pin which may be inserted into the device from the free front end thereof, said propelling device being driven by periodically repeated impact strokes applied thereupon by an impacting member. The propelling device acts upon the wire pin without any clamping means being involved, which is achieved by the propelling device being designed as a transmitting member against which the free end face of the wire pin may evenly abut and which may transmit the impact strokes of the impacting member as impact pulses into the wire pin through the free end face thereof, with the impact pulses propagating through the wire pin as periodic compression waves so that the wire pin is successively driven into the bone material.
