Abstract: An endoscope (29) having a handle (1) in which a light source (2) and a video camera (3) are directly integrated, and additional endoscope components can be coupled via a quick-coupling (5). The additional endoscope components can be probes, catheters or control elements, for example, that can be modularly combined into an endoscope.

Abstract: An endoscope (1) in which at least two light outlets (7, 10) for illuminating the field of view are provided, each of which forms a light cone (8, 11). The angles of beam spread (9, 12) of the light cones (8, 11) are different and at least the light cone (11) with the smaller angle of beam spread (12) can be switched on and off.

Abstract: An endoscope (1) having a handle (5) and a probe (2) that can be connected in an interchangeable manner, with an imaging system (40) having an imaging optic (29) and an illumination device (32) arranged in the handle (5). The handle (5), at its distal end, has a coupling (4) for connection to the probe (2), and the probe (2) is interchangeable and provided with an image conducting fiber bundle (8) and a light conducting fiber bundle.

Abstract: An endoscope (1) has a handle (2) as well as a probe part (3) that can be connected thereto via a coupling (4), with an illumination device as well as an eye-piece (17) with an imaging optic being arranged in the handle (2) and image conductors and light conductors in the probe part (3). The coupling includes an image interface and a light interface. In the coupling area, at least one axially engaging guide (6, 8) as well as bayonet-like engaging coupling parts (6, 5) are provided, one of which is embodied as a rotational locking part (5). In the final locked position the locking part (5) is secured by a snap. Preferably, the coupling (4) is provided with an axially engaging guide and additionally axially engaging guides (13, 15; 14, 16) are provided of the illumination system and the image transmission system, which are particularly arranged side-by-side.

Abstract: An endoscope (1) is provided having a handle (2) and a probe part (3) that can be connected thereto, with an illumination system comprising at least one light emitting diode (6) and a video system having an image receiver being arranged in the handle (2). A carrier element (12) made of a heat-conducting material is provided for at least one light emitting diode (6) inside the handle (2), to which the light emitting diode (6) is directly connected. The carrier element thermally contacts the housing parts and/or installation parts of the handle (2) and the probe part (3) for heat conductivity and/or dissipation.

Abstract: A microendoscope with a distal probe tip which has, in particular, a diameter of up to approximately 1 mm is provided and inside of which an optical subassembly at least provided with a micro-objective and with an image transmitting element is accommodated. An image transmitting system is connected to the optical subassembly. An image-enlarging coupling element is provided between the optical subassembly of the probe tip and the image transmitting system connected thereto. The image transmitting system connected to the coupling element has a larger active diameter than the optical subassembly that is provided with the distal objective. As a result, the distal probe tip on a handgrip has the necessary small working diameter over the entire working length, and at the beginning or inside the handgrip, the optical coupling element is coupled to an image guide or to an image transmitting system or the like having a higher pixel count and thus a larger active diameter and, therefore, a larger outside diameter.
