Abstract
A vibration-transmitting medical tool-coupling device includes a first coupling element and a second coupling element, wherein one of the two coupling elements is designed as a coupling protrusion insertible into a coupling recess on the other coupling element, wherein the coupling protrusion and the coupling recess each have a first section having a thread with at least one thread flight for releasable connection of the two coupling elements and one second section which is designed so that the two coupling elements can be positioned relative to one another and are displaceable along the shared longitudinal axis before the two coupling elements can be connected releasably to one another by the thread. A guide ring which extends around the coupling protrusion is provided on one end of the thread which is arranged on the coupling protrusion and the at least one thread flight of the thread ends at this guide ring.
