ABSTRACT:
A roll-back tube system, preferably for an endoscope, for moving an inner shaft which is guided in a roll-back tube of the type that is rolled back at both ends. The tube is driven via a number of friction wheels, suction cups or tracks which act on an inner tube section in order to drive the system in a continuous movement. In order to seal off the gap between the shaft and the inner tube section, front and rear turn-back areas in each case form a bead which bears sealingly on the shaft. The admission of lubricant into the gap between shaft and inner tube section takes place via an essentially radial shaft bore in the area of the roll-back tube, which shaft bore is either connected to an external admission line via the shaft cavity or an inner line, or else via a rear clamping piece by means of a lubricant injection shoe adapted to the shaft surface.
