FIELD: medical engineering. SUBSTANCE: device has casing, bushing, flexible tube, bearing cable with gripping basket and handle. The handle is made in rod form and is provided with graduation lines and wedge-like groove mounted in the casing. The bushing is set over the handle and is provided with a window facing the groove. The end of the flexible tube is connected with the casing by means of a nut with elastic bushing. To attach the bearing cable to the handle, its end is brought through the handle wedge-like groove to take it out from the bushing window to bring to the casing generatrix. The graduated spring mounted in the casing opening is compressed by the bushing end. The bushing travels along the groove and presses the cable in the window with pulling force not exceeding the permissible valve. The required opening the basket is carried out by fixing handle with screw to the casing generatrix. EFFECT: accelerated treatment course.
