The treatment center of the treatment device may be represented on the display in at least one picture of the locating device on the display, and operating elements are provided, with which the positioning in coordinates of the locating device may be controlled.

Abstract: The endoscopic instrument has at least one component that heats up during the operation of the instrument and is equipped with means for automatically registering the use or non-use state of the instrument. The instrument has a control, which actuates the at least one component in a power-reduced fashion or switches off the at least one component during the non-use of the instrument, and which actuates the component with the power provided for the use or switches on the component during the use of the instrument.

Abstract: A medical instrument includes a hollow shank and an instrument section arranged pivotable to the hollow shank proximate the distal end of this hollow shank. An instrument part is mounted in an axially movable manner in the pivotable instrument section.

Abstract: An endoscopic instrument has a proximally arranged operating part, a distally arranged instrument head and a shaft connecting the operating part to the instrument head. A number of instrument channels guided through the shaft open out on the instrument head. These instrument channels run obliquely outwardly in the distal direction with respect to a central axis of the instrument head in a section of the channels that adjoins the distal openings thereof.

Abstract: An endoscopic instrument has a shaft designed in a flexible manner along its longitudinal axis in at least one section. The flexible section of the shaft has a tube-shaped wall made of an electroactive polymer with a plurality of control electrodes and reference electrodes respectively embedded therein. As seen in the axial direction, the control electrodes and reference electrodes are respectively arranged alternately and separated from one another. The control electrodes and reference electrodes alternating in the axial direction respectively have a rigid design and are respectively interconnected in an electrically conducting manner in the axial direction by elastic webs arranged on the outer or inner circumference. A method is also provided for producing a flexible section of such an endoscopic instrument.

Abstract: With a method for manufacturing a bendable tube, which is preferably envisaged for an endoscopic instrument, first a tube is separated into several tube sections in a manner such that adjacent tube sections engage into one another with a positive fit in the axis direction of the tube. After the separation of the tube into several tube sections, one envisages peripherally arranging means for providing a positive fit transversely to the axis direction of the tube, on the regions of the tube sections, which are situated in engagement with one another.

Abstract: An endoscopic instrument includes a shank which is bendable in at least one section and an endoscope head forming the distal end of the shank and in which the distal-side interfaces of the instrument are arranged. The endoscope head is bendable and is designed as one piece from an electroactive polymer. Electrodes are arranged in the endoscope head in the polymer, which may be subjected to electrical voltage.

Abstract: Local tissue areas should be thermally destroyed when using ultrasound thermotherapy. Traditionally, mono-frequency continuous wave ultrasound signals are used to this end. These lead to a non-optimal distribution of heat or to a non-optimal localization of the heating inside the tissue. In practice, the following dosage problem arises: the prevention of unwanted tissue damage in the tissue located in front of the target area while simultaneously having a sufficiently high damaging effect in the target area. The aim of the invention is to optimize the distribution of heat or to increase the localization of the heating. To these ends, modified transmitted signals (e.g. multi-frequency signals) are used that are adapted to a specific utilization of the non-linear ultrasound propagation and attenuation properties inside the tissue.
