Description

Endoscopic system

The basic concept of all previously known endoscopes is characterized by the fact that all necessary elements are always included Form a self-contained, generally non-demountable / instrument.

Endoscopes that can be extended with tubular pieces are also in use, but an instrument always forms one in itself closed type.

The KJ-e-Mt ^ urt '. the underlying idea is to ο a system

create, going beyond the state of the art, the user, through a high degree of interchangeability of the elements to open up the possibility of adding a required component to the instrument set for the to expand new use.

It should also be possible to replace a defective part immediately without any difficulty.

To solve the problem, the U <eu. <Dr ** Q 'is thereby

characterized in that a base unit with a support body

is provided which unites the pipe system and the nozzle for the connection of the light guide and that the basic unit is designed like a building block for the image-side connection of various lenses and obj ^ fcßejit-ig ¹ , for: 'connection of various imaging systems.

The essential feature of the present jUi> Hei ~ u> q is that the endoscopic system, which can be put together in the modular principle from complementary individual parts and opens up the possibility of being continuously improved with technical innovations for everyone To cope with problems of inspection of cavities.

Furthermore, if the individual components are defective, they can be replaced immediately, also by the user yourself, guaranteed.

The endoscopic system can be operated visually as well as on television and on the photo camera. The system is generally in the range of visible light, but with special components also in the adjacent Radiation area operational.

ζ This basic unit is formed by a pipe system that is formed from an inner and an outer tube, which are firmly connected to a support body. The space between These tubes are filled with fiber optics, the basic material of which can be glass, quartz or a plastic. They serve the Conducting light, infrared or ultraviolet. The fiber optic ends distally flush with the tube ends, proximally in a connection piece for the attachment of a flexible fiber light guide, for example. The pipe system of the basic unit can have any diameter and length, the support body is always uniform.

The basic unit `` takes '' the optics system inside

on, which is contained in a separate pipe system. It essentially consists of the lens and one or several reversing systems.

The optical tube system is in the support body by a detachable screw connection held.

The optical system is designed in such a way that the last image plane is at a certain distance outside the support body so that it is above all additional units

can be taken.

The optic generally directs the view straight ahead distally. The lighting illuminates the overlooked Object field.

A tube that can be pushed onto the tube system of the base unit and rotated and a prism or mirror with the necessary outlet opening is located in the distal tip () is used to divert the direction of vision and illumination, for example to the side.

All supplementary or additional units can be attached to the support body be connected. These units generally have focussing devices around the image plane that has been adopted adapt to the respective purpose.

Such supplementary and additional units are, for example, eyepieces of various magnifications, television adapters, photo adapters, Binocular, projection device with control screen, angle adapter, reflection adapter for Crosshair- ο .ä.> EiTispi ^ geluncj, Verjängungstubus or

-6-other possible, also special constructions.

Due to its universal interchangeability, the endoscopic system described is able to deal with all inspection problems that may arise to solve.

The endoscopic system of the present invention is thus characterized in that a fiber optic lighting tube, suitable for object field illumination, with light or ultraviolet radiation, to which both a fiber optic Light guide, as well as a light source can be attached, inside the tube with the optical image guidance system receives, while from the outside of a rotatable mirror or prism tube for the distal redirection of the gaze and illumination direction is included, and on the proximal body part the connection for focusable eyepieces of various Magnification, adapter for TV operation, photography, for mirroring crosshairs or reticules and has for projection onto a control screen.

The subject matter of the present application results not only from the subject matter of the individual patent claims, but also from the combination of the individual claims with one another.

All information and features disclosed in the documents, in particular the space shown in the drawings Training is claimed as essential to the invention, insofar as they are new to the state of the art, individually or in combination.

In the following the VJ ^ eΛακ «is based on only one Execution way illustrated drawing explained in more detail. Here go from the drawings and their description |

further features and advantages of the $ that are essential to the invention

emerged. |

This shows:

The support body 1, the pipe system 2 and the nozzle 3 for the connection of the light guide combined. The distal light and viewing direction 4 are straight ahead directed against the object field plane 5. The deflecting pipe that can be pushed onto the pipe system 2 and rotated 6 in the distal tip of which a prism or mirror is mounted 7, has at 8 the exit opening for the new direction of observation.

ν The image plane 9 lies proximally at a certain distance from the connection level 1o, in which the extension tube 11, the mirroring adapter 12, the angle adapter 13, the binocular 14, the projection device with Control screen 15 etc. can be connected. By attaching the extension tube 11 or the Mirroring adapter 12, a new connection level 16 is obtained, which enables the connection of monocular 17, television adapter 18 - the TV camera is indicated at 19 Photo adapter 2o - the photo camera is indicated at 21 or further units permitted.

ι rι ti lu_ it ti

When attaching the angle adapter 13 is also the Connection level 16 obtained after the connection piece 22, to which the aforementioned units 17 to 21 can be attached are.

The embodiment presented does not limit the expandability of the endoscopic system in any way.
