Abstract
A medico-technical device, such as an endoscope (1), has an everting tube (3) that encloses an endoscope shaft (2) for driving the latter. To minimize friction incurred by relative movement between the endoscope shaft (2) and the everting tube (3) and/or friction between two opposed surfaces of the everting tube (3), a lubricant is applied to the areas. To accomplish this, at least one of the everting tube (3) and the endoscope shaft (2) are coated with a first component provided in solid matter. By adding a second component, which reacts with the first component, to the first component, the first component liquefies and/or swells so as to develop its lubricating properties.
