Embodiment Construction

[0053] exist figure 1 and figure 2 In the exemplary embodiment shown in , an endoscope 1 according to the invention comprises an endoscope shaft 2 with a distal end 3 which is at the same time the distal end of the endoscope 1 . The end of the endoscope shaft 2 remote from the distal end 3 is connected to the main body 4 of the endoscope 1, which has an optical unit connection 5 for an optical recording device 6 (e.g. a video camera) or an optical coupling device (which can be including, for example, a C-mount connection 13 or a bayonet connection). Furthermore, the main body 4 includes a light connector 7 . exist figure 1 Only schematically shown in the illustration is an optical recording device 6 comprising, for example, an optical unit 8 and a CMOS sensor 9 and which may, but need not be, be part of the endoscope 1 according to the invention.

[0054] The endoscope 1 can have an objective lens D1 at its distal end 3 in the endoscope shaft 2, behind which objective len...

Abstract

An endoscope has an endoscope shaft 2 and a main body 4, the main body is connected to the endoscope shaft 2, and a first dial 12, 50 that has a first contact surface is mounted on the main body in arotatable manner. The main body 4 has a second contact surface against which the first contact surface bears. The contact surfaces move against one another when the first dial 12, 50 is rotated. A first setting unit E1, E2 is provided, using which a pressure force with which the first contact surface is pressed against the second contact surface is settable in order to set a minimum torque that isnecessary in order to rotate the first dial 12, 50.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102018130553.2 filed on November 30, 2018, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an endoscope having an endoscope shaft and a main body connected to the endoscope shaft and on which a first turntable is rotatably mounted. Background technique [0004] Such a rotatable turntable is provided, for example, on an endoscope in order to set the focus position of the focusing optics unit by rotating the position or to rotate a camera connected to the turntable for common rotation. In order to rotate the turntable, a certain minimum torque must be applied. To manufacture an endoscope such that a desired minimum torque is set, very high tolerance requirements are placed on the components in question, resulting in a complex and expensive manufacture.
