It is about 40-45cm, "Total corono scopie 1 left and right colon bending through one person operation method" (Gastrointestinal endoscope Vol. 5 No. 5 1
- the flexible portion 10 in the anus 28 can be about 60 to 70 cm from the endoscope tip 8. It is known from the above-mentioned documents and the like.
- the proximal portion of the flexible portion 10 is made thicker to make it more difficult to bend, and it is possible to twist the required amount with less force.
- at least a part of the tapered section 1 O c must be at least 70 cm ahead of the distal end 8 of the endoscope. 10b hardly enters the large intestine, and the expected effect cannot be obtained.
- the endoscope distal end portion 8 is located in the large intestine in most patients.
- the flexible portion 10 becomes more difficult to bend, and the restoring operation of the sigmoid colon 30 to return to the original shape can be prevented.

- FIG. 7D shows a state where a part of the sigmoid colon 30 is sharply bent. As shown in FIG. 7D, when the intestinal walls are bent sharply enough to abut (or adhere) to each other, the bending angle of the bent portion reaches a maximum of about 180 °.
- the bending portion 9 can be bent to about 180 °,
- the small-diameter portion 10a which is the distal end of the flexible portion 10 provided continuously to the curved portion 9, is also naturally curved as much as possible by 180 ° up to 180 °. Is desirable.
- the small-diameter portion 10a when the small-diameter portion 10a is bent with a minimum radius, the small-diameter portion 10a has a length sufficient to be bent by 180 °. It can be passed relatively easily.
- the tapered portion 10c and the large-diameter portion 10b are harder than the small-diameter portion 10a, so if the small-diameter portion 10a is too short, the flexible portion 10 is bent to 180 °. And it is difficult to pass through sharp bends in the large intestine.
- the axial length of the small diameter portion 10a, the tapered portion 10c, and the large diameter portion 10b By appropriately setting the relationship, the sharpest bent portion can be passed through relatively easily, and the insertability of the endoscope insertion portion 2 is improved.

- the outer diameter of the flexible portion 45 may be set to be substantially the same.
- the insertion section 2 of the first endoscope 1A In order to smoothly introduce the insertion section 2 of the first endoscope 1A into the large intestine, it is not only dependent on the structure of the insertion section 2 itself, but also that the operator who operates it has less fatigue. It is also important.
- the insertion part 2 is grasped by the right hand, and the operation part 3 is grasped by the left hand. Take action.
- the right hand pushes / pulls and twists the insertion part 2, but in general, the outer diameter of the flexible part 10 is large, so that the necessary twisting operation can be performed with less force, especially in the twisting operation, so that fatigue is less.
- each operator has an outer diameter of the flexible portion 10 that he or she is accustomed to on a daily basis. Just because the larger the outer diameter of the flexible part 10 is, the less fatigue is felt, but when the extremely large flexible part 10 has not been handled before, the feeling of discomfort increases, and Leads to.
- the outer diameter of the large diameter portion 10b of the first endoscope 1A is changed to the flexible portions 45, 46 of the other second and third endoscopes 1B, 1C.
- the operator is less likely to feel uncomfortable when operating the first endoscope 1A because the outer diameter is set within the range between the thickest outer diameter and the thinnest outer diameter.
- the outer diameter of the large diameter portion 10b of the first endoscope 1A is set to be substantially the same as the outer diameter of the flexible portion 45 of the second endoscope 1B. The operation can be performed with less discomfort.
- the tapered portion 10c and the large diameter portion 10b provided on the flexible portion 10 of the first endoscope 1A have more than half of the total length (effective length) of the insertion portion, the operation is not performed.
- the outer diameter of the small-diameter portion 10a is temporarily smaller than that of the flexible portion 46 of the third endoscope 1C. Even if the outer diameter is smaller than the outer diameter, at least the outer diameter of the tapered portion 10c and the larger diameter portion 10b is equal to the outer diameter of the flexible portion 45 of the second endoscope 1B and the third inner diameter.
- the small-diameter portion 10a may also be gripped at the beginning of insertion or at the end of removal, so the outer diameter of the small-diameter portion 10a is also higher than the flexible portion 45 of the second endoscope 1B. It is preferable that the outer diameter of the small-diameter portion 10a be set within the range of the flexible colon 46 of the third endoscope 1C. If they are set to be almost the same, operation without a feeling of strangeness can be performed.
- a sense of discomfort when the operator operates the insertion section 2 of the first endoscope 1A is significantly reduced. can do.
- FIG. 9 shows a third embodiment of the present invention. Note that the shape of the insertion portion is the same as that of the insertion portion 2 described in the first embodiment, and a description thereof will be omitted.
- connection portion outer skins 4 8 and 49 are provided with connection portion outer skins 4 8 and 49.
- the figure shows a state in which the outer skins 48, 49 of both connection parts are arranged.
- various kinds of materials such as a hard tubular portion, an adhesive, and a soft heat-shrinkable tube can be applied to the connection portion outer skins 48, 49.
- the outer diameter of the large-diameter portion 10b provided on the proximal side of the flexible portion 10 is substantially the same as the outer diameter of the connection portion skins 48, 49 ( ⁇ 5%). Or that The dimensions are set slightly smaller than these. For example, if the outer diameters of the outer sheaths 48 and 49 are 12.8 mm, the outer diameter of the large diameter part 10 b is set to 12.8 mm. The outer diameter of the small diameter part 10 a is 11 . Set to 5 mm.
- the outer diameter of the connection portion outer skins 48 and 49 is often set to be larger than the outer diameter of the flexible portion 10. Therefore, in the process of introducing the endoscope into the large intestine, the large intestine part where the distal end part 8 and the curved part 9 can pass through the lumen observed at the distal end part 8 first has a flexible part 10 following it. There is nothing difficult to pass.
- the portion having the large intestine is moved to the tip portion 8 or the curved portion 9 If the gap between the inner wall of the large intestine and the distal end portion 8 or the curved portion 9 is extremely narrow, the subsequent large diameter portion 10b may not be able to pass or may be difficult to pass .
- the outer diameter of the large diameter portion 10b is substantially equal to or less than the outer diameter of the connection portion 48 or 49, a portion through which the outer diameter 48 or 49 of the connection portion can pass is provided. Can also pass through the large-diameter portion 10b, so if it becomes difficult to advance the insertion portion 2 smoothly, the cause may not be due to the thickness of the large-diameter portion 10b. Since it is known in advance, it is only necessary to cope with the same cause inference as in the conventional endoscope insertion section 2.
- the distal end portion 8 of the insertion portion 2 and the curved portion At least one of the sections 9 and between the curved section 9 and the small-diameter section 10a provided on the distal end side of the flexible section 10 are provided with connecting section outer skins 48, 49 connecting the respective sections,
- the outer diameter of the large-diameter portion 1 Ob provided on the proximal side of the flexible portion 10 is set to be substantially the same as or slightly smaller than the outer diameter of the connecting portion outer skins 48 and 49.
