Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope capable of displaying various information within the field of view of the finder.

A conventional endoscope is constructed as shown in FIG. In other words, ■ is an endoscope, 2 is a distal end, 3 is a curved part, 4 is a flexible part, 5 is an operating part, 6 is an image guide, 7 is a light guide, and 8 is a light source device, which is installed in the operating part 5. Observations are made by looking through the viewfinder.
The viewfinder field of view 9 has an observation image 9a located at its center as shown in FIG. When using this type of endoscope, especially when performing radiofrequency ablation using the endoscope, various information such as pulse rate, blood pressure, body cavity pressure, temperature, scope insertion depth can be obtained while looking through the endoscope's finder. It is possible to obtain recorded data such as patient biological information such as X-ray irradiation time, recorded frame number, code 7 that identifies the patient, and the final time of the temporal change record (February 1st, 2015 or minute 2 seconds 2 o'clock). If possible, it would be very convenient from the standpoint of safety and record organization, but such an endoscope did not exist before.

In view of the above points, the present invention provides an electronic viewfinder that can be used in place of the conventional optical viewfinder of an endoscope, and can display various information within its field of view. The purpose is to provide endoscopes,
To explain this with reference to the embodiment shown in the drawings below, the third
In the figure, 10 is a solid-state image sensor such as a CCD that receives light from the image guide 6 of the endoscope via an imaging lens 11, and 12 is a camera control unit that converts the signal from the solid-state image sensor lO into a video signal. 13 is a deflection device that shifts the center of the observed image to a position a predetermined distance a from one end of the viewfinder field of view (see Fig. 4); 14 is a switch circuit; and 15 is a deflection device assembled in the operating section of the endoscope The elaborate display device 16 is a video pattern generator for displaying instruction signs such as arrows and crosses within the field of view of the finder, and its position is at or near the operating section of the X that can be operated by hand. - It can be adjusted by the Y dial 17. Reference numeral 18 denotes a video character generator for displaying information within the field of view of the finder, into which data such as recording frame numbers are input using a manual input device 19 such as a keyboard, and a pulse rate measuring circuit and a thermometer (not shown) are input using an automatic manual input device 20.

Information such as biological information is input from a pressure gauge, an electrocardiograph, etc. via an interface.

Reference numeral 21 denotes an alarm circuit, which sends a signal to the switch circuit 14 when the signal from the automatic input device 20 exceeds a preset upper or lower limit, causing the observation image to disappear or flash on the display device 15, and if necessary. video pattern generator 16 and /''!.

By sending a signal to the Take video character generator 18, an instruction sign and/or warning information displayed on the display device 15 is made to flash, or a warning mark is displayed near Take Take to issue a warning. It has become. Here, on the screen of the display device 15, the viewfinder visual field 22 is displayed as shown in FIG.
The center of the observed image 22a by the endoscope is located at a distance a from the right end of the finder visual field 22, and various information is displayed in the left display area 22b.

Since the embodiment of the present invention is configured as described above, various information such as biological information and data is displayed in the finder field of view 22, and in particular, the observation image 22a is arranged close to one side of the finder field of view 22. Good, wide display area 22
b can be provided, so more information can be displayed within the viewfinder field of view 22. Further, when specific information exceeds a preset upper or lower limit, a warning is displayed in the viewfinder visual field 22 via the alarm circuit 21.

As described above, according to the present invention, various information can be displayed within the viewfinder field of view when the endoscope is used, and an alarm is issued when there is an abnormality, that is, when specific information exceeds a preset upper or lower limit. Since the information can be displayed within the field of view of the endoscope, the user can learn various information such as information about the patient such as pulse rate, data such as recording frame number, etc., without taking his eyes off the viewfinder. This has the effect of shortening the examination time and making it easier for the patient9.Furthermore, in the event of an abnormality, the patient can detect the abnormality by looking at the warning display. Furthermore, since the viewing image is moved to one side within the field of view of the finder, a wider display area can be provided, which is effective.

In addition, in the above explanation, various pieces of information are displayed simultaneously within the field of view of the finder, but it is also possible to display not only one piece of information at the same time, but also to display several pieces of information at the same time, and to switch them sequentially. Can display more information about an item. That is, for example, changes in the patient may be known by displaying several pieces of time-lapse data at regular intervals for one piece of information, and only the necessary data can be displayed using a switch (not shown) provided on the operation unit. It may also be called up and displayed on the display section. Also, when recording, if you take the signal from point A in Figure 3, you will get a signal of only the observation slope image, and if you take the signal from point B, you will get the signal of the observed image including various information, so switch these as appropriate. All you have to do is record it. Furthermore, although FIG. 3 shows an endoscope equipped with an electronic finder instead of the conventional optical finder, it may also be possible to use it in place of the conventional optical finder; in this case, a turret type Various switching mechanisms are possible, such as a sliding type, a movable reflective mirror flip-up type, etc.
