- Video endoscopes are used in medicine and technology to study hard-to-reach cavities.
- endoscopes have an elongate shaft with a proximal end, that is arranged close to the user, and a distal end, that is to say remote from the user.
- the shaft can be flexible or rigid.
- a lens is arranged, which images an image of the cavity to be examined on an electronic image converter.
- the image converter converts this image into electrical video signals.
- the image converter may be, for example, a CCD or CMOS chip.
- the video signals generated by the image converter are conducted via a signal line to the proximal end of the shaft, where they are output via a connection element, if necessary after an electronic preprocessing.
- the endoscope shaft is rotated about its longitudinal axis during use, for example to obtain a better viewing angle to a detail of interest, then the horizon position of a video image reproduced from the video data is rotated
- the image converter is often rotatably mounted in the shaft about the longitudinal axis of the shaft.
- the image converter is mounted in a tubular sleeve, which in turn is rotatably mounted in the shaft. The rotation of the sleeve can
- a magnetic coupling which is the rotation of a Rotary ring arranged outside of the shaft transmits through the shaft to the tubular sleeve.
- the connecting element at the proximal end of the shaft is usually hermetically sealed to the proximal end of the shaft and thus can not rotate with the tubular sleeve. Therefore, between the image converter and the
- Connection element used a flexible signal line.
- a corresponding video endoscope is known, for example, from DE102007009292A1.
- a video endoscope comprising an elongated shaft having a distal end and a proximal end, a lens disposed at the distal end of the shaft, and at least one image converter disposed proximal to the lens in the shaft, wherein the at least one image converter is surrounded by a tubular sleeve which is arranged rotatably in the shaft about a longitudinal axis of the shaft, and wherein the at least one image converter is connected via a flexible signal line to a connection element arranged at the proximal end of the shaft, which is further developed thereby; that the flexible signal line is releasably secured in the tubular sleeve by means of a position securing element.
- the flexible signal line may comprise a flexible printed circuit board. Flexible printed circuit boards are easier to contact than cables, for example, and at the same time have a smoother
- a video endoscope according to the invention may comprise two image transducers arranged in a common tubular sleeve.
- two imagers are used in 3D video endoscopes to enable stereo endoscopic imaging.
- the connection points of the image converter with the signal lines are particularly sensitive because of the cramped space.
- the flexible signal line of a corresponding video endoscope may comprise a separate flexible printed circuit board for each image converter.
- the position securing element can be inserted from the outside into the tubular sleeve.
- the position securing element can be introduced particularly simply after the connection of the flexible signal line to the image converter, in order to fix the signal line.
- the position securing element may have a slot-shaped receptacle for the at least one flexible printed circuit board.
- the position securing element can then be inserted into the tubular sleeve in such a way that the slot-shaped receptacle slides over the flexible printed circuit board and fixes it in the process.
- the position assurance element may consist of two sub-elements, which deform so elastically when inserted into the tubular sleeve, preferably mutually, that the at least one flexible circuit board is fixed non-positively in the slot-shaped receptacle.
- opposing walls of the slit-shaped receptacle of a partial element can be compressed by the other partial element, whereby the flexible circuit board is clamped between the walls.
- Each of the two sub-elements may have a slot-shaped receptacle for a flexible printed circuit board. It may then be first used in the tubular sleeve so that the slot-shaped receptacle of the first sub-element engages over a first flexible circuit board, the first sub-element. Subsequently, the second sub-element can be used so that the slot-shaped receptacle of the second sub-element engages over a second flexible printed circuit board.
- one of the two sub-elements may have two slot-shaped receptacles for each flexible printed circuit board.
- the second sub-element is used in this case only for elastic deformation of the first sub-element to fix the flexible circuit boards in this.

- the distal lens assembly 1 1 is rotatably connected to the shaft 2.
- a tubular sleeve 15 is provided in the shaft 2, which is rotatable about a longitudinal axis of the shaft 2.
- the tubular sleeve is coupled via magnets 16 with the rotary ring 7 such that rotation of the rotary ring 7 is transmitted to the tubular sleeve 15 about the longitudinal axis of the video endoscope 1.
- a proximal objective part 17 and an electronic image converter 18 are mounted in the tubular sleeve 15 in a rotating manner.
- a flexible signal line 19 connects the image sensor 18 with a connection element 20 at the proximal end 4 of the shaft 2.
- the connection element 20 is inserted hermetically sealed into the shaft 2.
- Signal processing unit 21 processes the signals and outputs them via a cable 8.
- the user can rotate the handle s. It also rotates firmly with this connected shaft 2 and the distal lens assembly 11. In order not to lose the horizon position of the image, the user keeps the rotating ring 7 so that it does not rotate. Accordingly, the tubular sleeve 15 is not rotated with the proximal lens assembly 17 and the image converter 18, and the horizon position of the recorded image remains constant.
- a position securing element 25 is provided which removably fixes the signal line 19 in the tubular sleeve 15.
- the torsional forces in the signal line 19 are received by the position-securing element 25 and delivered to the tubular sleeve 15, without any connection points of the signal line are loaded with the image converter.
