Kupplung zum dichten Verbinden zweier schaftartiger medizinischer Instrumente

摘要

A coupling is used for sealingly connecting two elongate medical instruments (10, 90) along their axes (53, 97), in particular for connecting an arthroscope shaft to an optical system. A first coupling element (80) with a contact surface (66) is arranged at a first instrument (10). A contact surface (106) of a coupling element (92) of the second instrument (90) can contact the contact surface (66) of the first coupling element (80). Also disclosed is a locking device for detachably locking both coupling elements (80, 92) together with their contact surfaces (64, 106) in sealing contact with one another. To make handling easier, the locking device has a slide (44) arranged on one of the two coupling elements (80) so that it can be moved transversely to the coupling axis (53). In a first position, the slide (44) allows the two coupling elements (80, 92) to be brought into contact with one another, and in a second locking position, the slide mechanically locks the two coupling elements (80, 92). One of the components (58) of at least one coupling element (80) provided with a contact surface (66) can be moved in the direction of the coupling axis (53).
