Abstract: An endoscope including an insertion tube for insertion into a patient's body cavity and a tip at the distal end of the insertion tube, the tip including a tip housing encapsulating an optical inspection device, a viewing window for or of the optical inspection device and a fluid spray nozzle having an outer wall providing a fluid channel surrounded by the outer wall for spraying a fluid onto the viewing window, the fluid spray nozzle having at least one fluid splitting element arranged in the fluid channel for providing a converging fluid flow out of the nozzle onto the viewing window.

Abstract: An endoscope including at least one operating element, a steerable deflecting element located at the distal end, an endoscope tip, and a steering wire having a first portion, a second portion and an intermediate portion, wherein the intermediate portion is attached to the deflecting element or to the endoscope tip, operation of the at least one operating element to apply a drag force to the first portion moving the endoscope tip in a first direction, and operation of the at least one operating element or another operating element to apply a drag force to the second portion moves the endoscope tip in a second direction different from the first direction, and/or wherein the intermediate portion of the steering tie element is at least in part received in a clearance provided at/in a distal end portion of the deflecting element and/or at/in the endoscope tip.

Abstract: A tip for a single use endoscope, the endoscope and a method of producing the tip. The tip includes a housing encapsulating a light emitting device and an imaging device in a fluid tight manner, where the light emitting device is arranged on a planar printed circuit board provided within the housing, and the housing at least in part is made from a transparent material and comprises at least one transparent light guiding part or light guiding section for guiding light emitted by the light emitting device to an outside of the tip.

Abstract: An endoscope with an articulated bending section body (1) including a number of segments including a proximal segment (2), a distal segment (3) and a number of intermediate segments (4, 4?, 4i) arranged between the proximal segment (2) and the distal segment (3). Each intermediate segment (4, 4?, 4i) comprises at least one through passage for a pull-wire (7). The intermediate segments include (4, 4?, 4i) at least one interface segment (4i) adapted to receive and retain the distal end of a tube (8) surrounding the at least one pull-wire (7).

Abstract: A medical visualisation device including an instrument elevator having a guide surface for engagement with an instrument protruding through a tip part instrument channel and a X-ray transparent housing. The instrument elevator is radiopaque and pivotable around a pivot axis to adjust a guide angle between the guide surface and a longitudinal axis. The pivot axis being substantially perpendicular to the longitudinal axis and a viewing direction. A control wire being coupled to the instrument elevator to transfer a force exerted on the control wire to the instrument elevator to adjust the guide angle.

Abstract: An endoscope including a control system including: a first control wheel connected to a first wire drum and to a first steering wire of the endoscope to control the bending operation in a first dimension, the first control wheel having a bearing surface; a second control wheel connected to a second wire drum and to a second steering wire to control the bending operation in a second dimension, the second control wheel having an outer bearing surface positioned farther from the axis of rotation than the bearing surface of the first control wheel; and an outer bearing element including an inner bearing surface positioned farther from the axis of rotation than the outer bearing surface of the second control wheel and abutting the outer bearing surface of the second control wheel so that rotation of the second control wheel is at least partly borne on the outer bearing element.

Abstract: An endoscope with a flexible endoscope shaft has an endoscope head arranged at its distal end. The endoscope head is a sleeve, open at both end faces. Functional units, such as an optical system, a working channel, an illumination and a cooling system for the illumination are accommodated in the endoscope head. The cooling system has a heat exchanger integrally formed with the sleeve in the latter which forms a closed cooling chamber for generating a coolant flow. The illumination, which is in the form of an external conductor plate supporting an illumination means, is arranged adjacent to the distal end wall of the heat exchanger, to discharge thermal energy via the end wall of the heat exchanger to the coolant flow. The external conductor plate is mechanically supported on, or has only a minimum distance from, the heat exchanger end wall.

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.
