Fig. 1B is a partially enlarged perspective view of the curved structural body 2, and it can be seen that the curved structural body 2 is formed by alternately connecting a large-diameter spiral pipe 4 and a small-diameter spiral pipe 5. As shown in fig. 1C, all the small-diameter spiral pipes 5 have the same axial projection position and are circles 5 ', and the circle centers of the circles 5 ' and the large-diameter spiral pipes 4 ' do not coincide with each other; the steering wires 3 thus pass from the fixed end 6 through all of the large diameter coils 4 and the small diameter coils 5 in sequence, and are finally connected to a bend control mechanism (not shown). When the control mechanism pulls the steering wire 3 in the direction of A1 shown in FIG. 1A, the controlled bending structure 1 starts from the fixed end 6 and turns to bend toward the side of the small diameter spiral pipe 5 to reach the position 1' shown in FIG. 1A; at this time, if the bending control mechanism loosens the control wire 3 in the direction a2 shown in fig. 1A, the controlled bending structure 1 starts from the fixed end 6 and rotates back to the side opposite to the side where the small diameter spiral pipe 5 is located to reduce the bending degree of the controlled bending structure, and the controlled bending structure 1 can be returned to the original straight state by continuing to loosen the control wire 3. Therefore, the controllable bending structure provided by the embodiment can generate controllable bending with different degrees at the side of the small-diameter spiral tube, and is convenient for the endoscope to be applied under the requirements of different bending degrees.

Similarly, when the bending control mechanism pulls the steering wire 32 in the direction A1 shown in FIG. 2A, the controllably bending structure 1 starts to bend from the fixed end 6 and rotates toward the side of the small diameter helical tube 52, as shown in FIG. 2A at position 12; at this time, if the bending control mechanism loosens the operating wire 32 in the direction a2 shown in fig. 2A, the controlled bending structure 1 returns from the fixed end 6 to the opposite side of the small diameter spiral tube 52 to reduce the bending degree of the controlled bending structure, and continuing to loosen the operating wire 32 can return the controlled bending structure 1 to the original straight state; it can be seen that the degree of bending rotation of the controllably bendable structure 1 to the side of the smaller diameter solenoid 52 can be controlled by controlling the tension on the steering wires 32. As shown in FIG. 2C, since the projected circumferences 51 ' and 52 ' of the small-diameter spiral tubes 51 and 52 in the axial direction are symmetrically distributed along the projected circumference 4 ' of the large-diameter spiral tube 4 in the axial direction, the controllable bending structure provided by the embodiment can be bent to different degrees in two directions 180 degrees apart, which is convenient for the endoscope to be applied under different bending requirements.
