Abstract

In a striking tool for surgical instruments with a sleeve-shaped gripping part, a tool holder which is slidingly displaceable in the latter in the longitudinal direction thereof, and an oscillatingly driven piston which is slidingly displaceable in the gripping part in the longitudinal direction thereof and has two striking surfaces which strike corresponding contact surfaces of the tool holder and thereby act upon the latter with impulses acting in opposite directions, to enable selective generation of blows in the striking direction and in the pulling-out direction without converting the tool, it is proposed that the actual stroke of the piston in the gripping part be limited such that is it smaller than the double-strike stroke which the piston would have to cover, with the tool holder held firmly in the gripping part, from the striking of the first striking surface against the contact surface to the striking of the second striking surface against the second contact surface, and that the tool holder be mounted for sliding displacement in the gripping part both relative to the gripping part and relative to the piston.
