Abstract
A lubricant supplying device of an endoscope everting tube drive comprises a drive tube everted at least once to thus form an outer and an inner tube portion. Inside the inner tube portion an endoscope shaft is mounted in an axially displaceable manner. In addition a drive device is provided which encompasses the drive tube everted at least once or the inner tube portion thereof so as to apply a driving force for an advancing movement of the endoscope shaft onto the inner tube portion, the drive means being in fluid connection with a lubricant supplying line and a lubricant discharge line for introducing a lubricant via the drive device into the drive tube everted at least once and/or for discharging it. The lubricant supply line and the lubricant discharge are connected to the drive device in two locations thereof diametrically opposite with respect to the endoscope shaft.
