ABSTRACT:
The luxation-proof drainage and instrument duct for the arthroscopy comprises a hollow cylinder (20) and a sleeve (30) longitudinally displaceable thereupon which are interconnected at the one end, while the sleeve (30), within the area of its connecting end, is constructed in such a way that, when the sleeve (30) is displaced towards the connection plane, a terminal area of the sleeve is outwardly expanded in a basket-like manner over the circumference of the sleeve, the basket-like expanded sleeve end being provided with a plurality of perforations (135') disposed so as to be distributed over the circumference and in side-by-side arrangement. The sleeve (30) is arrested on the hollow cylinder (20) in the expanded state of the terminal section of the sleeve (FIG. 1).
