仁とができず、所望の変位１得られなくなる。The endoscope *, 1 configured in this manner bends and breaks the curved pipe tube that displaces the tip component l to any desired position using the curve operation knob S, and inserts the tip into a desired affected area within the body cavity. It is used for observation, photography, treatment, etc., but the part that curves and displaces in the up, down, left and right directions is the part where the dye tip i@K is attached. A curved pipe operating wire 1, called an angle wire, is operated and shown in FIG.
By pulling 4 in the direction of the arrow k, the curved tube ν is curved, and the tin end portion is displaced. Therefore, when manipulating the curved pipe, a force is applied in the direction opposite to the direction of the pulling force applied to the angle wire 14#IC to prevent the flexible pipe 11 from simultaneously bending due to the pulling of the angle wire 140. You must support 11! There is a ball. Conventionally, as a support means for the flexible tube 11, a coil lug formed in the shape of one pipe is used as shown in FIG.
L This coil intestine is placed in a flexible tube U, inside of which 6
The Ca angle wire 14 is inserted through the sand and the flexible tube, and its spring force always applies a force in the direction from the operation section main body 3 to the tip component n. Therefore, when attempting to bend the curved tube at a large angle by pulling the angle wire 14, the coil tube supporting the flexible tube 11 has a correspondingly large spring support force. If the spring force of the coil that supports this flexible tube U is weak, the flexible tube U will curve. Therefore, the desired displacement 1 cannot be obtained.

できなくなるという欠点があった。Conventionally, a single-thread coiled trout as shown in No. 3 wJK has been used as a tube-shaped coil that supports such a flexible tube 11. However, the single-threaded coil has a weak stiffness and cannot be used. If this is continued, the coils will come into close contact with each other over time, and the length of the coil will be reduced due to the application of force, resulting in a gradual decrease in the flaring effect.As a result, the flexible tube 11 will not be bent. The force supporting the bending pipe is reduced, and the bending force of the bending pipe is reduced. Therefore, there was a drawback in that it was not possible to displace the tip component □ to the desired affected area.

A pipe-shaped coil is formed by using a multi-thread coil as the coil and increasing the spring force that supports the flexible tube U.
It is an object of the present invention to provide a flexible tube for an endoscope that is provided with a multi-thread coil □ that increases the rigidity of the flexible tube 11.

程度のものが実用上好ましい。A multi-thread coil, such as a six-thread coil, formed in this manner is placed inside the flexible tube 11 and used. Because of the close contact and the breaking effect, even if a compressive force is applied to this multi-thread coil by operating the angle wire 14, the restriction to reduce the length of the coil over time is less than that of a single-thread coil. becomes extremely small. Therefore, in order to support the flexible tube 11 when bending the curved tube, it becomes much hotter than a single-thread coil. In addition, in the embodiment shown in Fig. 4,
Although the pipe-shaped coil has 6 turns, it is practically preferable to have 6 turns or about 6 turns.

果が得られる。As described above in detail with reference to embodiments, according to the present invention, the pipe-shaped fill in which the angle wire is inserted is formed of a multi-thread coil, so that it can be replaced with a conventional single-thread coil. Compared to the formed tube, the spring effect changes less over time and is more rigid. As a result, the performance of the endoscope can be improved by bending the curved tube to a desired angle and accurately displacing the tip component. Effects can be obtained.
