Abstract: Provided is an endoscope with a handle and an endoscope shaft connected to the handle, which has a bendable section and a rigid section, adjoining it, with a support extending in the longitudinal direction of the endoscope shaft, wherein the bendable section has a flexible outer tube the end of which facing the rigid section rests on the support, wherein a fixing sleeve is connected to the end section and covers the end of the outer tube facing the rigid section such that said end is clamped for fixing between the fixing sleeve and the support.

Abstract: An endoscope is provided, comprising a first tube whose distal end is sealed with a cover glass disposed in a mount and an electric heating system for heating the cover glass, with the heating system comprising two electric connections which can be connected with a power source, and an electrically conductive coating which is applied to the inside of the cover glass and comprises two mutually spaced contact sections, of which one each is electrically connected with one of the connections, and with the mount being electrically conductive and a first of the two contact sections being electrically connected via the mount with the associated connection.

Abstract: The invention relates to a medical instrument for cutting biological and especially human tissue, having a hollow cutting tube that can rotate by means of an engine around its longitudinal axis, on whose distal end at least one blade is mounted, as well as with a handle in which the cutting tube is mounted for control purposes. In order to produce a medical instrument for cutting biological and especially human tissue in which the powering of the cutting tube is of simple construction and involves minor losses of capacity, it is proposed with the invention that the engine is configured as a hollow-shaft engine mounted on the cutting tube.

Abstract: An endoscope is provided, comprising a first tube (11) whose distal end is sealed with a cover glass (15) disposed in a mount (14) and an electric heating system for heating the cover glass (15), with the heating system comprising two electric connections (6, 7) which can be connected with a power source, and an electrically conductive coating (22) which is applied to the inside (19) of the cover glass (15) and comprises two mutually spaced contact sections (23, 24), of which one each is electrically connected with one of the connections (6, 7), and with the mount (14) being electrically conductive and a first (23) of the two contact sections (23, 24) being electrically connected via the mount (14) with the associated connection (6, 7).
