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).

Abstract: A sterile disposable arthroscopy camera cover made from tubular film folded onto itself and forming a package including a plurality of folded layers of film. One end portion of the tubular film extends into and through the other end portion of the tubular film and in the direction of the other end so that the two tubular film ends are located at the same side of the film package. The folded layers which comprise the package may extend in the direction of the tubular film axis or transversely of the axis.
