Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an endoscope with a warning device, specifically an endoscope with a warning device that issues an alarm when the tip of the endoscope comes into close contact with the intestinal tract, etc. Regarding mirrors.

[Conventional technology]

When inserting an endoscope into a body cavity to perform diagnosis and treatment inside the body cavity, especially in narrow intestinal tracts such as the large intestine, the endoscope may be inserted into the target site while manipulating the angle. The tip of the speculum often comes into close contact with the intestinal tract. In such cases, the operator of the endoscope (hereinafter referred to as the operator) should visually check the direction of the angle knob of the endoscope, or use his intuition to detect the direction of close contact. The angle was manipulated in the opposite direction to the direction in which the endoscope was in close contact, so that the tip of the endoscope and the intestinal tract were separated.

[Problem to be solved]

By the way, as mentioned above, there is no problem when the tip of the endoscope can be moved away from the area that is in close contact with the angle operation, but if the angle operation is performed in a complicated manner such as up, down, left and right. When doing
If the patient is accidentally operated in a direction that is closer to the patient, it may cause pain to the patient, or in severe cases, it may cause a hole in the intestinal wall, requiring a separate surgery to immediately repair the hole. There was a high possibility that something would happen.

[Means and effects for solving the problems] In order to solve the above problems, the present invention provides a color detection means near the rigid tip of the endoscope, and uses the output signal of the color detection means to issue a warning means. When the hard end portion approaches a predetermined colored portion, a warning is issued to notify the user of the approaching condition.

〔Example〕

Hereinafter, the present invention will be explained based on illustrated embodiments.

Figures 1 (8), (B), (C), and (D) are electrical circuit diagrams showing the first embodiment of the present invention, a front view of the rigid distal end portion of the endoscope, and a view of the screen of the endoscope. It is a figure showing display operation.

As shown in FIGS. 1(^) and (B), a forceps channel outlet 2 is formed in the upper part of the front end surface of the rigid distal end part 1a of the endoscope, and an observation window 5 is provided in the lower part. . Lighting windows 3.4 are arranged on the left and right sides of the front end surface, and the lighting windows 4
A nozzle 12 for air and water supply is formed approximately midway between the observation window 5 and the observation window 5 . A sensor 11 is disposed in the center of the front end surface of the rigid tip portion 1a, and the sensor 11 has a photoelectric conversion element covered with an appropriate filter so that it is sensitive only to red light.

Furthermore, sensors 7 and 8 similar to the sensor 11 are disposed on the left and right side surfaces of the rigid tip portion 1a, respectively.
Further, similar sensors 6 and 9 are arranged on the upper and lower side surfaces of the rigid tip portion 1a.

The sensor 6 is connected to an inverter 18 via an amplifier 13.
and a first input of the input OR gate 24. The output end of this inverter 18 is connected to the output end of the light emitting diode 25.
The input terminal of is connected via a resistor 31 to a terminal that supplies the operating voltage Vcc. Similarly, sensor 7 is amplifier 14
through the inverter 19 and the second of the OR gate 24.
The output end of this inverter 19 is connected via a light emitting diode 26 and a resistor 32 to a terminal for supplying the operating voltage Vcc.

Similarly, sensor 8 is connected to amplifier 15. Inverter 21,
Light emitting diode 27. The sensor 9 is connected to the resistor 33 and the OR gate 24, etc., and the sensor 9 is connected to the amplifier 17 and the inverter 23.
9 light emitting diode 29. Resistor 35 and or gate 24
etc., and the sensor 11 is further connected to the amplifier 16. Inverter 221 light emitting diode 28. The resistor 34 and the OR gate 24 are connected to each other. The output end of the OR gate 24 is connected via an inverter 36 to one end of a buzzer (BZ) 37 that emits a warning sound.
The other end of 7 is connected to a terminal that supplies operating voltage Vcc.

And the light emitting diode 25, 29.27°26.
As shown in FIG. 1(C), the endoscope 28 is disposed at the top, bottom, left and right, and at the top of the right corner outside the field mask of the approximately square endoscope that is visible when looking through the eyepiece. That is, for example, when the upper surface of the rigid distal end portion 1a of the endoscope (in FIG. 1(B)) approaches the intestinal wall, the light emitting diode 25 disposed above the field mask lights up as described below. This informs the operator that the rigid tip portion 1a is approaching the upper surface.

The endoscope with a warning device configured as described above can be operated as follows. That is, as shown in FIG.
The flexible IC is inserted, for example, into the intestinal tract 41 of the patient. When the rigid tip portion 1a comes into close contact with the intestinal tract 41, a so-called reddish phenomenon occurs in which the entire field of view of the field mask becomes reddish, but in this case, any one of the sensors 6 to 11 lights up, Displayed on the field of view mask (Figure 1 (C)
reference). That is, any one of the sensors 6 to 11 reacts to the red color of the inner wall of the intestinal tract 41, and electric signals are generated in these sensors 6 to 11, which are sent to amplifiers 13 to 17, respectively.

For example, the output signal of the sensor 6 is transmitted to the amplifier 13.
The signal is amplified by the inverter 18 and sent to the first input terminal of the OR gate 24. Then, the light emitting diode 25 connected to the output end of the inverter 18 lights up, and the buzzer 37 connected to the output end of the OR gate 24 via the inverter 36 sounds.

On the other hand, since the light emitting diode 25 is disposed above the field mask as shown in FIG. I know that there is. Since the light-emitting diode 25 lights up in this way, the operator immediately pulls the light-emitting diode 25 in the direction in which the light-emitting diode 25 lights up, that is, in the direction opposite to the direction in which the rigid distal end portion 1a of the endoscope is currently facing (that is, in a downward direction). f) You can judge that it is best to operate the angle. This is caused not only by the display of the light emitting diode 25 for the sensor 6, but also by the positions where the respective sides of the rigid tip portion are close to each other even when the other light emitting diodes 26 to 29 are lit. All you have to do is angle the tip so that the hard tip faces in the opposite direction.

In addition, as shown in FIG. 1(D), the light emitting diodes arranged around the field mask are arranged in triangular displays 25A to 29A.
By doing so, the direction in which the rigid tip portion moves can be clearly displayed, making it easier for the operator to understand.

Next, a second embodiment of the present invention will be described based on FIG. 2. In this embodiment, the same members as those shown in the first embodiment are given the same reference numerals to avoid redundant explanation. Further, in this embodiment, an optical fiber is disposed at the rigid tip, the color of the affected area obtained by the optical fiber is captured by a photoelectric conversion element, and the output is processed appropriately.

As shown in Figure 2, there are 5
A number of optical fibers 42-46 are arranged. The tip end surface 42a of the optical fiber 42 is the tip rigid portion IA.
The distal end surface 46a of the optical fiber 46 is disposed so as to be exposed on the lower surface of the rigid tip portion IA. The distal end surface 45a of the optical fiber 45 is disposed at the center of the front end surface of the rigid distal end portion IA of the endoscope, and the distal end surfaces 43a and 44a of the optical fibers 43 and 44 are respectively disposed on the left and right sides of the rigid distal end portion IA. It is arranged. These optical fibers 42-46 are connected to amplifiers 13-17, respectively, via photoelectric conversion elements 47-52, respectively.

Even with such a configuration, the intestinal tract 4 is
1 (See Figure 3) When the endoscope is inserted, the colored position on the field mask is displayed using a light emitting diode, and a buzzer sounds to alert the operator. can be emitted.

Although the present invention has been described with respect to an endoscope, a gastroscope, a fiberscope, or a C instead of a fiberscope may also be used.
It goes without saying that the present invention can be applied to an electronic scope using an OD and an endoscope having an angle operation mechanism. Furthermore, if a sensor sensitive to a certain color is used not only for endoscopes applied to the human body but also for industrial endoscopes,
Of course, it can also be applied in the same way.

[Effect] According to the present invention, the operator can easily know that the rigid distal end of the endoscope is extremely close to the inner wall of the canal, so the operator can immediately move the rigid distal end in a direction away from the inner wall. Can be treated. Therefore, the risk of damaging the inner wall can be eliminated.
