- Torque transmission is evaluated by the difference between the rotation angle on the base end side (corresponding to the treatment section) and the rotation angle on the distal end side (corresponding to the treatment section) when the base end side (corresponding to the operation section) of each rope is rotated.
- a torque transmission evaluation test was carried out on the ropes of Examples and Comparative Examples as follows.
- a double spiral having a diameter of 200 mm is formed for each rope of Example 1-12 and Comparative Examples 1 and 2.
- This double spiral is formed by inserting, for example, the test rope 2 into the inside of a small diameter pipe 22 that is formed in a double spiral shape having a diameter of 200 mm and both ends are linear. Done.

- a broken line extending at an angle of 45 ° with respect to the horizontal axis and the vertical axis starting from 0 ° indicates the proximal end in the entire measurement angle range (range of the input rotation angle from 0 ° to about 720 °). It is a straight line indicating that the difference between the rotation angle and the rotation angle on the tip side is zero.
- the difference between the rotation angle on the proximal end side and the rotation angle on the distal end side, which is the evaluation target of the test rope, is expressed as the difference in the vertical axis direction between the 45 ° inclined straight line and the measurement value curve in the figure.
- This difference in rotation angle corresponds to the rotation angle on the base end side.
- the difference in the rotation angle is shown larger than the actual difference for easy understanding.
- the maximum angle difference among the measured rotation angle differences is set as an evaluation target.
- the maximum angle difference between the ropes of Example 1-12 and Comparative Examples 1 and 2 is shown in Tables 1 and 2 by the index when the maximum angle difference of Comparative Example 2 is 100. The smaller the maximum angle difference, the smaller the exponent value and the better the torque transmission.
- the operating rope according to the present invention is suitable as an operating rope for a medical instrument.
