- the 64a penetrates a plurality of (in the embodiment, 4) 65a constituting the 2 65 and is held in a piercing state.
- the value of 65 is set in the same manner as the relation of each part in the above-described four modes. 0131 In other words, when comparing 64 of 2 of 65, 64 of 2 of 64
- Permission is set at the section of 65-64 of guide tube 2-2.
- the inner tube 2 provided with the soft 65 64 thus configured is completely the same as the above-described fourth embodiment.
- the same effect can be obtained.
- by simply arranging 65a on 64a made of the same material as 64 it is possible to construct 2 65, which is a significant difference from 64. Therefore, it can contribute to the cost of the strike on the productivity.
- the distal end guide portion fixed to the end of the guide tube 2 provided at the foremost end, joints 66, and made of a linear material 64 64 And a set of 2 65s formed by linking a plurality of bodies together.
- Reference numeral 66 denotes a movable connection made of a body like the leader 5.
- 64 of Lead 5 is defined by the same 64a as 64 mentioned above. This 64a penetrates a plurality (in the embodiment, 4 x 28) of 65a that make up a set of 2 65 It is kept stabbed.
- a strike, 64b is provided at the 65th place of 2 of 0139 of 64.

- the distal end portion in the present embodiment is configured such that a set of two 65s is disposed across the 66, thereby providing two bendable portions.
- the values of 64, 64, and 65 of the inner tube 2 are all set in the same manner as the relation of each part in the above-described embodiment. That is, when comparing 64 of 64 of and 65 of 2,
- the inner tube 2 having the soft 65 64 64 54 formed in this way Is as follows.
- the user grips the guide tube 2 and enters the inner tube 2 having the leading 5, 65 64 64 65 64 from the gate of the patient 7 lying on the bed 8 into the large intestine. Then, 5 of the guide tube 2 comes into contact with the wall. [0149] In this contact state, the guide tube device was rotated to hold the guide tube 2, and advanced toward the body cavity. As a result, the guide tube 2 travels deep into the large intestine. Then, the inner tube 2 entered from the gate advances toward the rectum 73 by the propulsion and the work of the person, and the inner tube 2 reaches 73 as shown in 48. In the state shown in FIG. 48, the lead 5 protruding from the end of the guide tube 2 is in contact with the surface of S73.

- the retaining seal material 84 is attached to the holding portion 83 of the guide tube 2 after the wire 5 is arranged. According to this configuration, the capscopy endoscope 8 fixed to the end of the wire 5 becomes free with respect to the guide tube 2. [0171] As a result, even if the size of the capscopy endoscope 8 is large, it is possible to surely prevent the intestinal wall from being subjected to an excessive rotation load, an excessively large amount of friction caused by the inner surface of the capscopy endoscope 8 to the wall. Can be. Also, since the image passed through the capscopy endoscope 8 does not rotate with the rotation of the guide tube 2, the guide tube 22 is not rotated. At the same time, ordinary image processing can be easily performed on a computer by using a new video processor, as compared with the case of image processing.
