Ausführungsbeliplel

Reference to a drawing is to be explained with a AusfOhrungsbeispiel the symbolically represented invention.

At the distal end 1 of the endoscope, the video camera 2 is installed in the insertion tube 3. At the proximal end 4, the microphone 6 is detachable to «eordnet. The output of the microphone 5 leads to the amplifier β which is connected to the discriminator 7. This is the output side of the controlled by the first input keyboard 8 switch 9 placed, which in turn is guided in the inputs of the latch 10 and the vocabulary store 11 also connected to the input keyboard β.

Both the cache memory 10 and the vocabulary store 11 are connected to the comparator 12, which is upstream of the evaluation unit 13. While the buffer 10 is coupled to the comparator 12 only in one direction, there is between the word memory 11 and the comparator 12 olna change connection. The evaluation unit 13 has the outputs 14 and 15. The first output 14 leads to the central controller 16, which is equipped with the second input keyboard 17. The central controller 16 is provided with the three outputs 18, 9 and 20. At the first output 18 which is connected to the second output 19 signal processing stage 21 coupled video camera 2 is connected. The third output 20 leads into the first input 22 of the image display unit 28 equipped with the inputs 22, 23, 24 and 25, which is connected to the signal processing stage 2Ί via the second input 23 and to the video memory 27 via the third input 24 in addition through the Aufzoichnungsleitunp 32 with the image display unit 26 is in communication. Parallel to this first, between evaluation unit 13 and image display unit 26 existing connection consists of a second, from

zweiton outgoing 15 of the evaluation unit 13 outgoing. This second connection initially leads into the transfer unit 28 and opens into the fourth input 25 of the image display unit equipped with the screen 29.

The system according to the invention operates as follows:

After the power supply of the system, not shown, is turned on, the insertion shaft 3 of the endoscope is inserted with the installed at the distal end video camera 2 in the not shown, to be examined organ.

Even before the start of the investigation, 11 passwords have been entered into the vocabulary memory. The input was made by storing a freely selectable password, eg. "In the microphone 5 was spoken while simultaneously entering a predetermined code, eg" six ", the i; i of the central controller 16 for recording a video image on the video memory 27 is preprogrammed. For the input of these and other key figures, the first input keyboard 8 is provided.

All code numbers predefined for the control function were provided with corresponding passwords and stored in the vocabulary memory 11 on this catfish. Another group of passwords, the definite findings in the endoscopic

Examining examinations are assigned to specific code numbers programmed in the transfer unit 28.

If the triggering of a control function is now required during the examination, the examiner will speak the assigned word In the microphone 5, wc In a known manner the sound vibrations are converted into electrical vibrations, which thereafter pass through the amplifier 6 and the discriminator 7 to an evaluable Form brought and stored in the cache memory 10. Subsequently, in the comparator 12, a comparison is made with the passwords present in the vocabulary phrases 11 and their finding a transmission of the associated code to the evaluation unit 13. The evaluation unit 13 evaluates this code and decides whether a forward Ober the first output 14 for

Central control 16 or above the second output 15 to the transfer unit 28 takes place.

In the central control 1 β then connected to the code obtained control process is triggered or

otherwise from the transfer unit 28, the associated with the code result identifier both in the memory 31 Obergeben as well as the image display unit 26 displayed directly on the screen 29. From the Blldwledorangebelnhelt 29 of this findings label can be recorded on the video memory 27 together with the recorded by the video camera 2 and also shown on the screen 29on the interior of the examined body in the presence of a corresponding Stoerbofohls the central controller 16.

After completion of the examinations, the findings recorded in the memory 31 are immediately printable by means of the printer 30.

But they can also be played on the screen 29. But there is also the possibility to make additions and deletions and then to print them out. It is not necessary to arrange the microphone 5 directly on the endoscope.

For example, it can also be worn as a laryngeal microphone. Similarly, the video camera is not bound to the insertion tube 3, but Ir, not shown form can also be attached to the eyepiece of the endoscope.

In endoscopic examination, the endoscope is to be operated by both hands to perform multiple functions

and it is directly guided by the examiner under visual control. So far were to execute another

Functions Auxiliary staff required or were qualitative deductions to the investigation or the result to be calculated. When using the invention additional functions can be realized without the need for an additional manpower

or an interruption of the examination procedure occurs. It is sufficient to pronounce a specific password in order to trigger the associated control function.

In the same way, it is now possible, during the examination process remarkable findings, in each case on

the body cavity section shown on the screen, immediately in direct connection with the respective

Fix the image without loss of information. It is not to be feared that words spoken during the investigation, but not in the Vocabularies are contained, lead to unwanted reactions. An unhindered exchange of information between the

In the case of examinations persons present is therefore guaranteed. The occupation of the vocabulary memory and thus the

Use of the entire system can be independent of the examiner's language or dialect. If the password treasure is from the vocabulary store on a nonvolatile storage medium, e.g. B. a floppy disk for the

each examining person is stored, so this vocabulary is for each additional led by this person

Examination available. Other investigators can do the same in their own way Schatzschatz work on the same endoscopy system. The application of the invention with respect to the immediate registration of findings is advantageously also not to the Use of a video camera bound to the endoscope, but can with appropriate modification in the same advantageous Be used even when using conventional endoakope.
