The carrier () is longitudinally moveably mounted in the tubular shaft () outside the optical guide tube (). The carrier is held distally from the optical guide tube () with a sliding tube () on the optical system () at a radial spacing from the axis of the optical system (). The carrier is also secured in the peripheral rotary direction to the optical guide tube () with a rotary lock (). The rotary lock has a bar () parallel to the carrier () and connected to it and a distally open elongate slot () in the optical guide tube ().
