ENDOSCOPE BENDING PORTION AND ENDOSCOPE |
摘要 |
An endoscope bending portion includes a tubular member provided with a treatment instrument channel and a string guide configured to hold wires, an interval of a plurality of first slots formed in a first tubular region on a distal end side is made to be smaller than an interval of a plurality of second slots formed in a second region at an intermediate portion, and a third interval of a plurality of third slots formed in a third tubular region is also made to be smaller than the interval of the plurality of second slots, and a dimensional ratio between a width and the interval of the first slots, a dimensional ratio between a width and the interval of the second slots and a dimensional ratio between a width and the interval of the third slots are equalized. |

1. An endoscope bending portion comprising:
a tubular member in which a treatment instrument channel for inserting a treatment instrument is disposed, a plurality of slots are formed in a circumferential direction, and a plurality of string guides that hold a wire on an inner circumferential portion are provided; the tubular member comprising a first tubular region at a distal end portion, a second tubular region at an intermediate portion and a third tubular region at a proximal end portion; a plurality of second slots having a second slot width formed at a second interval in the second tubular region; a plurality of first slots having a first slot width formed at a first interval which is smaller than the second interval in the first tubular region, a dimensional ratio between the first slot width and the first interval being set to be equal to a dimensional ratio between the second slot width and the second interval; and a plurality of third slots having a third slot width formed at a third interval which is smaller than the second interval in the third tubular region, a dimensional ratio between the third slot width and the third interval being set to be equal to the dimensional ratio between the second slot width and the second interval. |
