Abstract:
A device for driving an elongated wire pin into bone material, comprising:a propelling device actable upon the wire pin when a front free end of the pin is inserted into the device, said propelling device being driven by periodically repeated impact strokes applied thereupon by a periodically driven impacting member,wherein the propelling device acts upon the inserted wire pin without any clamping means, andwherein the propelling device further comprises a transmitting member which transmits elastic impact waves to the wire pin when the free end of the inserted wire pin evenly abuts the transmitting member, the transmitting member transmitting the impact strokes of the impacting member as periodical impact pulses into the wire pin through the free end of the wire pin so that each impact pulse propagates through the wire pin in the form of a compression wave, whereby the wire pin protruding from a front end of the device is periodically and progressively drivable into the bone material.
