Abstract:
A coupling for a leakproof connection of two medical instruments, each medical instrument having a shaft, said coupling is performed along a coupling axis extending along a shaft axis of said shafts of said medical instruments, havinga first coupling element arranged on a first medical instrument, said first coupling element having a first contact surface,a second coupling element arranged on a second medical instrument, said second coupling element having a second contact surface, said first contact surface of said first coupling element can be brought into contact with said second contact surface of said second coupling element along said coupling axis, andan interlock system for releasable interlocking the two coupling elements to one another, with said contact surfaces resting against one another in a leakproof fashion, whereinsaid interlock system has a slider which is displaceable transversely to said coupling axis between a first position and a second position, and said slider is arranged in transversely displaceable fashion at one of said two coupling elements;said slider allowing in said first position the two coupling elements to be applied against one another, and in said second position mechanically interlocking the two coupling elements,wherein at least one of said coupling elements is provided with a component having said contact surface of said coupling element, said component being displaceable in direction of said coupling axis, andwherein said contact surfaces of said coupling elements are configured as conical surfaces.
