Generally, industrial flexible endoscopes are used to inspect the insides of jet engines, heat exchangers, etc., or containers and pipes for chemicals and waste. By the way, there are many sharp corners and edges inside the jet engine, heat exchanger, etc. mentioned above, and when inserting and withdrawing the endoscope, the outer surface of the insertion part may be damaged by these sharp parts. I had a problem with it. Conventionally, in order to prevent such damage, the outer periphery of the insertion portion has been covered with a flexible tube made of braided metal wire.

However, since the above-mentioned protective tube was provided with a substantially uniform tension from the distal end side to the proximal end side, when the tension at the distal end side curved part is adjusted to the tension that makes it easy to curve, the proximal end There were cases where the endoscope was not easily inserted due to insufficient rigidity on the side. Further, when the tension is adjusted to the proximal end side to facilitate insertion, the distal end side cannot be sufficiently curved, which may impede observation and insertion.

Hereinafter, the present invention will be explained according to an embodiment shown in the drawings. In the figure, 1 is an operation section of the endoscope, and 2 is an insertion section. The insertion section 2 has flexibility, and accommodates therein an objective lens 3 and an image guide 4 of an observation optical system, a light guide 5 of an illumination optical system, and the like. The outer circumferential surface of the insertion portion 2 is coated with a synthetic resin material having chemical resistance, and the surface is smooth. Protective tube attachment parts 6, 7, and 8 are provided at the distal end, proximal end, and intermediate part of the insertion section 2, respectively.
are provided, and these protection tube mounting parts 6,
7 and 8 have outer diameters slightly larger than the outer diameter of the insertion portion 2. A hollow tubular protection tube 9 is detachably attached to the outer periphery of the insertion portion 2. The protection tube 9 is made by braiding thin metal wires into a hollow tube shape, and is configured so that a slight gap is formed between it and the outer circumferential surface of the insertion portion 2. In addition, the protective tube mounting portions 6, 7, and 8 of the insertion portion 2 are provided at the distal end, base end, and intermediate portion of the protective tube 9.
Annular mounting portions 10, 11, 12 corresponding to
is formed. The mounting portion 10 at the distal end fits onto the outer periphery of the protective tube mounting portion 6 at the distal end of the insertion portion 2 and engages with the distal end thereof.
Further, the intermediate mounting portion 12 is fitted onto the outer periphery of the intermediate protection tube attachment portion 8, and a fixing screw 13 is inserted through the attachment portion 12 and screwed into the protection tube attachment portion 8.
It is fixed in the axial direction by. The attachment portion 11 at the proximal end is slidably fitted in the axial direction on the outer periphery of the protection tube attachment portion 7 at the proximal end, and is rotatable to the tension adjustment member 14 screwed onto the distal end of the operating portion 1. is fitted. Then, by screwing this tension adjustment member 14, the proximal end of the protection tube 9 is pulled,
Applying tension between the proximal end and the middle part of the protection tube 9,
The structure is such that the rigidity of this part can be adjusted.

浄は容易である。 An embodiment of the present invention configured as described above is such that when inspecting an object with sharp parts inside, such as a jet engine or a heat exchanger, the inspection is performed with the protective tube 9 attached to the insertion section 2. will be carried out. Since the protective tube 9 is made of braided metal wire, it will not be damaged even if it comes into contact with sharp parts, and the insertion portion 2 will be reliably protected. Alternatively, the tension adjustment member 14 may be threaded to apply tension between the intermediate portion and the proximal portion of the protective tube 9 to increase the rigidity of only this portion and bend only the distal portion. This makes insertion, etc. easier.
Note that equipment with sharp parts inside, such as jet engines, are generally clean inside, so
Corrosive chemicals and the like will not adhere to it, and even if such a protective tube 9 is used, it will not be corroded. Next, when inspecting the inside of a container for chemicals or dirt, etc., the tension adjustment member 14 and the fixing screw 13 are removed, and the protective tube 9 is removed for inspection. As a matter of course, there are generally no sharp parts inside containers or piping for chemicals or waste, and the insertion section 2 will not be damaged even if the protective tube 9 is removed. In this case, the protective tube 9 has been removed, and the surface of the insertion section 2 is smoothly coated with a chemical-resistant synthetic resin material, so even if chemicals, dirt, etc. adhere to it, it will not corrode. They are easy to wipe off. In addition, when inspecting equipment that has sharp parts and corrosive chemicals inside, the protective tube 9 should be installed and inspected. Immediately after the inspection is completed, the protective tube 9 should be removed. What is necessary is to clean the protective tube 9 and wipe off chemicals adhering to the insertion section 2. In this case, the protective tube 9 is inserted into the insertion section 2.
It is easy to clean because it can be removed from the body and cleaned only.
