Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides an endoscope remote photography device that enables reliable remote photography with simple operations [Technical background of the invention and its problems] In recent years, endoscopes have been widely used in the medical and industrial fields.

The above-mentioned endoscopes have an elongated insertion section that can be inserted into a body cavity, and the desired area can be observed from the rear eyepiece. You can wear it and take photos.

However, when taking pictures by attaching a photographing device to the eyepiece via an adapter or directly, the weight concentrates on the eyepiece, making it difficult to perform operations such as observation or photography. However, there has been a problem (particularly in the medical field) that diagnosis, surgery, etc. cannot be carried out smoothly.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. 55-158030, the present applicant attached a viewing mirror to the eyepiece of the endoscope and attached a photographing device to the child eyepiece of the viewing mirror. We have proposed an endoscope remote photographing device that can be mounted to reduce the weight of the endoscope eyepiece and enable observation from the observation eyepiece of the viewing scope, and that can also remotely control and take photographs. .

The above-mentioned conventional example has excellent operability, allowing observation and photography to be performed with simple operations. Insert the tightly wound coil into the
Utilizing the flexible characteristics of both of these, the structure was such that power was transmitted by moving the coil back and forth with respect to the flexible tube. Therefore, when the amount of bending is large (that is, when the curvature is small), the relationship between the inner diameter of the tube and the length of the coil changes, and the protruding stroke of the coil at the operating end presses the release button (as a shooting stopper). In some cases, the tube is not strong enough to operate, or due to buckling or deformation of the tube, the frictional force with the coil increases, making it impossible to operate.

This has led to failures such as not being able to obtain desired photographs, and it has been inconvenient that it has become impossible to obtain materials that are essential for diagnosis and the like.

Furthermore, it is necessary to pay attention to the deformation of the tube during storage management, such as by taking care not to deform it by stepping on it during use, and by storing the tube without bending it too much.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and provides an endoscope remote photographing system that enables reliable photographing by reliably transmitting remote control operations with simple operations. The purpose is to provide equipment.

[Summary of the invention] By using air pressure to control an air release that is removably attached to a photographic device that is attached to the secondary eyepiece of a viewing mirror that is attached to the eyepiece of an endoscope. , has achieved the above objectives.

, 23B (indicated by P+ and P2 in FIGS. 8 and 9), and the first time relay 6 (also indicated by TR+) and the time relay 6 perform on/off control. the second time relay 8 (denoted as TR2) and the solenoid 37A of the pinch valve 36A (SQL+
) is also supplied with electricity. moreover,
On/off control is performed by the second time relay layer 8 (
After a predetermined time delay, the solenoid 37B (SO of the pinch valve 36B)
L2) is also energized.

By the way, the first time relay 6 has a second time relay after being energized.
The time relay 8 turns the time limit contact 77 from on to off after a time longer than the time it takes to turn the time limit contact 79 from off to on, and the timing thereof is shown in FIG.

The operation of one embodiment configured in this manner will be described below.

Connect the plug 30 to the outlet 71, and turn on the interlocking power switches 74 and 75 (SW+). By turning on the foot switch 27 at an appropriate time (indicated by tl in FIG. 9) at which photographing is desired, the air pumps 23A, 23B (P+) are activated.

Pz, ) operates, and one solenoid 37A (SQL+) is energized through the ON state time-limited contact 77, and the pinch valve is connected to the T-type joint 24A in the middle of the air supply path on the one air pump 23A side. 36A closes the exhaust passage, and the pressurized air is sent to the air release 18A side through the cable 19A. In this air release 18A, the piston 62 and piston rod 63 are moved forward by air supply, and the tip of the protruding piston rod 63 pushes the lever 57 forward, and at the same time, the other lever 51 also moves in the direction shown by the arrow E2.

Time t2J:J when the shutter plate 49 closes the optical path.

At time t3, when the rain falls, the second time relay 8 turns on the time limit contact 79 from off to turn on the solenoid 37B (SO
L2) is energized, and the air pressurized by the other air pump 2 is sent to the air release 18B side through the cable 19B. Similarly, the piston rod in the air release 18B is pushed out and the release button 15 of the camera 13 is pressed, and the shutter in the camera 13 (reference numeral 80 in FIG. 9) is pressed.
Indicated by

) (in FIG. 9, the high level side is open), and this operation is transmitted to the light source device 6 side via the cord 16 connected to the adapter 14, and the photographic lamp (flash lamp) (the high level side is open). (indicated by reference numeral 81 in FIG. 9) emits light, and when the exposure amount is sufficient for photographing under illumination by the lamp 81, it is detected by a photometric means (not shown) and the light emission is stopped. At time t4 after this light emission stops, the time limit contact 77 is turned off by the first time relay 6 (TR+). Then both solenoids 3
7A (SQL+>, 37B (SOL2) is no longer energized, each exhaust passage opens and the pressurized air is discharged, and each piston rod 63 of each air release 18A, 18B returns to the rear, and the inside of the camera 13 is removed. shutter 8
0 closes, the shutter plate 49 of the anti-glare shutter 17 returns to the position where the open hole 45 is opened. When the piston rod 63 in the air release 18B on the camera 13 side returns to the right, this operation is transmitted to the light source device 6 side via the cord 16, illumination light for observation is turned on, and the coarse viewing section 9 It will return to a state where it can be observed from behind. Therefore, if the user stops stepping on the foot switch 27, the operation of each amplifier 23A, 23B will also stop, all photographing operations will be completed, and the camera will return to its initial state.

In addition, the operation of the air release 18B on the camera 13 side is normally set to have a time lag of 0.1 seconds or more with respect to the operation of the air release 18A on the anti-glare shutter 17 side to ensure sufficient anti-glare. It is possible to take pictures with objects.

According to one embodiment that operates in this manner, the camera 13 is attached to the child side eyepiece 12 via the image guide cable 10 in the bendable viewing mirror 8, so that the light-weight coarse side viewing portion 9 is installed. It can be observed from the foot switch 27.
By stepping on the hollow cables 19A, 19
Each air release 18A is caused by the air pressurized through B.

18B is operated remotely, there is almost no loss in motion transmission due to bending, etc., and the motion is reliably transmitted and the camera 13 attached to the child eyepiece 12 can take flawless photographs. You can take pictures.

Moreover, since the control is air-type, the cables 19A and 19B are prevented from buckling (which often occurs in the conventional example), and durability is improved. Furthermore, since it is an air-type control, the lengths of the cables 19A and 19B can be set freely, and the range of application is widened without being restricted by the environment in which it is used.

Further, it can be easily attached to and detached from the viewing mirror 8 for use.

In addition, in the above-mentioned embodiment, two air pumps 23A are used.
, 23B are installed together, but for example, one air pump 23A and one pinch valve 36A are connected to the other tube 25B with a solenoid valve interposed therebetween, and the solenoid valve is controlled to open with a slight delay. It can perform almost the same function. In this case, use a T-type joint, etc., if necessary.

In the above-mentioned embodiment, the shirt cover plate 49 that shields the open hole 45 has a semicircular cutout shape, but is not limited to this shape, and may be square or other shapes. A shape without a notch may also be used.

Furthermore, the air release 18A has a similar structure to the air release 18B attached to the camera 13, and can be attached by screwing together, but it is not limited to examples with the same structure, and can be attached and detached using other setscrews, etc. It can also be used as an adhesive,
It may be fixed by brazing, soldering, etc.

In the above description, the pressurized air is supplied to operate the anti-glare shutter 17 and the shutter of the camera 13, but the present invention is not limited to this, and the anti-glare shutter 17 side By disposing a liquid crystal plate on the optical path passing through the open hole 45 and applying an alternating current voltage of a frequency that cannot be followed by the liquid crystal component, for example, an anti-glare means through which almost no light is transmitted is formed. can do. In this way, there is no need to consider the timing operation of operating the anti-glare shutter 17 side first as in the first embodiment.
By simultaneously operating the foot switches 27, it is possible to achieve substantially the same effect as described above.

That is, the note switch 27 immediately turns on the air pump 2.
3B side is operated to open the shutter of the camera 13 using the pressurized air, and at the same time, an alternating current voltage is applied to the liquid crystal panel through a signal cord instead of the cable 19A to block light. In this case, the liquid crystal panel cannot follow high frequencies such as the above-mentioned AC voltage (actually not very high) and exhibits light-shielding properties as mentioned above, but by supplying pressurized air, the above-mentioned air Since the light shielding time is earlier than the operating time when the air release 18B is pressed, the glare can be prevented before the flash is emitted by the air release 18B. In this way, the structure of the anti-glare shutter can be simplified and it can be made lighter. Further, signal transmission is possible with a cord having a smaller diameter than the hollow cable 19A, and this cord can be integrally fixed to the image guide cable 10 to make it easier to operate.

The light shielding by the liquid crystal plate does not have to be complete, but may be such that the light enters the observer's eyes to the extent that it does not interfere with observation,
On the other hand, if the light is slightly incident, you can know that the flash has fired, and if the flash stops at the appropriate exposure level,
You can also know that the exposure has stopped.
Thereafter, the foot switch 27 can be turned off and continued observation can be continued immediately.

In addition, when the flash stops firing, press the note switch 27.
It is also possible to have a configuration in which the circuit is brought into a floating state and the operation of the air pump or the like is stopped. If you do this, 7=toswitch 27 at the timing of shooting.
It is triggered and operates when you step on it, so
There is no need to spend the time required to shoot (although it is actually a short amount of time).

Note that the synchronization signal and the EE double signal are sent to the light source device 6 side by the cord 16 connected to the adapter 14, and the flash light is automatically adjusted. , photometry may be performed on the film surface, and the photometry means is not limited.

Further, the film in the camera 13 may be wound by a normal manual operation, but it is more desirable if the film is wound automatically by pressing the release button 15 after taking a picture.

It is clear that the present invention can be used not only for rigid endoscopes but also for flexible endoscopes.

Furthermore, in the first embodiment, the hollow cable 19B
By making one hollow cable 19A substantially longer than the other hollow cable 19A, it is possible to operate the pressurized air at the same time, and as a result, the anti-glare shutter 17 can be closed first.

In this way, one air pump can be operated at the same time without requiring one time relay 6, 78 or the like. In this case, for example, there is a cap 2 in the control device main body 21.
The length of the tube may be equivalently increased by making the side of the tube 25B connected to the tube 28 longer, or by providing a hollow container in the middle.

[Effects of the Invention] As described above, according to the present invention, it is possible to take pictures by controlling the opening and closing of the shutter of a camera via a pump and a hollow cable that transmits air accompanying the operation of the pump for remote control. In addition, since it has a structure that prevents glare during photographing, the transmission of motion is reliable, so reliable photographing is possible, and it is lightweight and easy to operate for observation and photographing.

Furthermore, since the means for transmitting the photographing operation of opening the shutter of the camera is an air type, it is durable and the length of the hollow cable can be set freely.
