摘要: A videoendoscopic system (1) including an endoscope optical system (2) and a camera portion (3), the endoscope optical system (2) having an elongated shaft (4) through which an optical image guide (5) and a fiber light guide (6) pass, and an end housing (7), which is proximally connected to the shaft (4) and has an image exit window (10) and a light entry window (8) with radiation directions that are parallel to one another and to the axis of the shaft (4). The camera portion (3) includes a camera housing (15), from which an image signal cable (24) and a light guide cable (20) pass out, and an image entry window (18) and a light exit window (19), which are arranged with parallel radiation directions at a distance from the windows (8, 10) in the end housing (7) and the end housing (7). The camera housing (15) is constructed with a rotationally fixedly lockable coupling device (7, 16, 25, 26, 19) for coupling the windows (8, 19; 10, 18) to one another in a centering manner. The the coupling device has a cylinder (7) on one of the housings and a matching bore (16) on the other housing (15). The windows (8, 10; 19, 18) are arranged in the end wall (11) of the cylinder (7) and the base wall (17) of the bore (16).

摘要: A ureteroscope (1) fitted with a stem (2) which exhibits at least at its distal end zone a substantially oval cross-section and which comprises a rounded beak (6) projecting at the distal end of the cross-section in the direction of the longer transverse axis (7), is characterized in that the beak (6) is asymmetrical to the transverse axis (7) in a manner that its center line (8) deviates increasingly from the transverse axis (7) as the radius increases.
