Endoscope
First Claim
1. An endoscope comprising a handle and a probe part that can be connected thereto via a coupling, with an illumination device as well as an eye-piece with an imaging optic being arranged in the handle and image conductors and light conductors being arranged in the probe part, the coupling comprising an image interface and a light interface between the handle and the probe part including at least one axially engaging guide as well as bayonet-type engaging coupling parts provided in a coupling area, one of which comprises a rotational locking part, wherein, in a locked position, the rotational locking part is secured by a snap, wherein the rotational locking part is arranged at the handle and an other of the bayonet-type engaging coupling parts comprises a coupling counterpart that is arranged at the probe part, the rotational locking part is provided with a flange-like appendage as a handle for rotating the rotational locking part, and the flange-like appendage of the rotational locking part is located in a locked position at least largely within a perimeter contour of the housing of the handle, wherein for snapping the rotational locking part into the locked position, the flange-like appendage of the rotational locking part snaps over a protrusion in the locked position, which is formed by a sheath-shaped guide part of the illumination system at the handle and a pin located at the probe part.

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.
