Medical quick coupling system for attaching a guide sleeve without tools

A medical quick coupling system for mounting a guide sleeve without tools, the medical quick coupling system comprising:

• at least one guide sleeve having a guide axis in which a medical instrument or a medical device is receivable and alignable or orientable in a direction of the guide axis;
• a quick coupling having a carrier sleeve into which the at least one guide sleeve is receivable, and a radially outer actuating sleeve, which is movable relative to the carrier sleeve with a first receiving position and a second fixing position;
• and
• a coupling mechanism disposed between the actuating sleeve and the carrier sleeve,
• the coupling mechanism being adapted so that an insertion of the at least one guide sleeve into the quick coupling moves the coupling mechanism from a first disengaged position into a second engaged position, the coupling mechanism thereby moving the actuating sleeve from the receiving position into the fixing position, and
• the coupling mechanism further being adapted so that an actuation of the actuating sleeve from the second fixing position against a pretension force into the first receiving position moves the coupling mechanism from the second engaged position into the first disengaged position.
