Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope apparatus having improved endoscope operating means.

[0002]

2. Description of the Related Art Generally, there are various types of means for operating an endoscope, such as bending of an insertion portion, air supply, water supply, or suction. As described in Japanese Patent No. 78639 and Japanese Patent Laid-Open No. 56-75131, the operation is performed by an operation member such as a knob or a button provided in an operation unit on the near side of the endoscope itself. That is, these operation members are concentratedly provided on the operation unit of the endoscope itself.

[0003]

However, such a system may cause inconvenience in use in some cases. In other words, the bending angle of the tip of the insertion part and the air and water supply,
The viewing device is attached to the endoscope operated by the operation section of the endoscope and observed by two observers, and one of these two is a teacher and the other one is a recipient. If there is
If the teacher is on the operator side (the endoscope holder side) and the instructor is on the viewing side, the instructed person cannot operate the endoscope.
The teaching contents and the actual operation of the endoscope do not connect. vice versa,
When the instructor is on the operator side and the instructor is on the viewing side, the instructor has no choice but to verbally teach the operating method, and the instructor is always worried about erroneous operation. In any case, the teaching did not go smoothly.

On the other hand, when the TV device is attached to the eyepiece part of the endoscope, the vicinity of the operation part becomes heavy, so that it is hung from the ceiling, but this deteriorates the operability remarkably. . The present invention has been made in view of the above problems, and an object of the present invention is to provide an endoscope apparatus capable of operating an endoscope at a desired place.

[0005]

SUMMARY OF THE INVENTION The present invention is an endoscope apparatus having at least two operation sections for operating the endoscope. In addition, a switch is provided that prioritizes the operation of an arbitrary operation unit of the plurality of operation units. Therefore, it is possible to operate the endoscope by selecting the operation unit located at a desired location.

By operating the air supply switch 35, the first solenoid valve 32 is opened and closed, The second solenoid valve 33 is opened and closed by operating the water supply switch 36. That is, by pressing the air supply switch 35, the first solenoid valve 3
2 opens, and the water supply switch 36 is pressed
The solenoid valve 33 is opened. Further, the air supply switch 35 is electrically connected to the air supply pump 29, and the water supply switch 36 is electrically connected to the water supply pump 31. Then, the first electromagnetic valve 32 is opened in association with the pressing operation of the air supply switch 35, and the air supply pump 29 performs the air supply operation. Further, the second electromagnetic valve 33 is opened in association with the pressing operation of the water supply switch 36, and the water supply pump 31 performs the water supply operation.

In addition, in the insertion portion 3, the operation portion 2 and the universal cord 4, the light guide 3 extends over them.
7 is inserted, the tip of the light guide 37 is connected to the illumination window 38 of the tip portion 16, and the base end of the light guide 37 is a light guide tube 39 provided in the connector 6.
It is connected to the. The light guide tube 39 receives illumination light from the light source 41 in the light source device 7.

An image guide 42 is inserted through the insertion section 3 and the operation section 2, and the tip of the image guide 42 is connected to the observation objective optical system 43 of the tip section 16.

On the other hand, the eyepiece section 11 on the parent side of the viewing apparatus 9
Is attachable to and detachable from the eyepiece 8 of the endoscope 1. In addition, a half mirror 44 as a light splitting means is provided inside the parent-side eyepiece section 11 to reflect a part of the light sent from the eyepiece section 8 of the endoscope 1, The rest is transparent. Then, the transmitted light is sent to the parent eyepiece lens 45 so that it can be observed at the parent eyepiece section 11. Further, the light reflected by the half mirror 44 is focused on one end surface of the viewing image guide 47 through the imaging lens 46. The image guide 47 is guided to the child side eyepiece 12 through the flexible tube 13,
Since it is optically connected to the child-side eyepiece lens 48 provided in the child-side eyepiece section 12, the same image as the image of the parent-side eyepiece section 11 can be viewed.
