227, entitled Urological Endoscope Particularly Resectoscope, issued to Wolfgang Ibe on Jan. 2, 1979, teaches a hollow cylinder sheath, a viewing device, an illuminating device, a resecting device and an outflow tube. The hollow cylinder sheath has a proximal end and a distal end. The viewing device is an endoscopic arrangement of optical elements. The illuminating device is a cooperating arrangement of fiber optics which is optically coupled to a light source. The viewing device and the illuminating device are located in the sheath extending from the distal end back to the proximal end. The outflow tube is slidable onto the sheath to surround the sheath and form together with the sheath an intermediate return-flow space between the outer wall of the sheath and the inner wall of the outflow tube, with the outflow tube when in position slid over the sheath tightly surrounding the distal end portion of the sheath. The resecting device is an electrode loop which is electrically coupled to an electromagnetic energy source. Clear rinsing water is introduced into the proximal end of the sheath. Turbid water is removed from the proximal end of the intermediate space. The outflow tube is provided with apertures at the distal end thereof for the flow of clear rinsing water out of the distal end of the sheath and around the end of the endoscope and then through the apertures into the intermediate space.
