Abstract
The distal insulated end of an endoscope shaft has an inner layer made from a material having a higher heat resistance than the material in the insulated end. Such heat resistant layer preferably contains a ceramic material and is constructed as an inner ring which is inserted and cemented into a correspondingly sized inner groove in the insulating material.
