The setting of the U-shaped connecting piece facilitates the mutual movement of the main bending control rocker and the additional bending control rocker.

[0008] Further, the endoscope operation host rear end is rotatably connected with an annular rotating ring outside the main bending control rocker, the annular rotating ring is fixedly connected with a second connecting rod, and the other end of the second connecting rod is fixedly connected with the rotating seat. The position of the rotating seat, the rotating ball and the additional bending control rocker can be adjusted by rotating the annular rotating ring to adapt to the hand shape of the user.

[0009] Further, the outer side of the annular rotating ring is fixedly provided with a worm wheel ring, and the endoscope operation host rear end is rotatably connected with a worm that is meshingly connected with the worm wheel ring. The position of the annular rotating ring is positioned by the meshing worm wheel ring and worm.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] To allow users to operate the joystick more comfortably and perform bending operations on the endoscope, a bending operation device for the endoscope is designed, such as... Figure 1 As shown, the device includes an endoscope operating unit 1, with a main bending control rocker arm 2 mounted at its rear end. The rear end of the endoscope operating unit 1 also features a handle 2 with control buttons. The bending angle of the insertion section at the front end of the endoscope operating unit 1 can be controlled via the main bending control rocker arm 2 and the control buttons, allowing observation at different positions. The insertion section can also be equipped with a display device for displaying the detected images. The above-mentioned parts are mature prior art, described in detail in patent CN209640597U, and will not be repeated here.

[0022] The core of this technical solution lies in the fact that an additional bending control component is installed at the rear of the endoscope operating host 1. The additional bending control component and the main bending control rocker arm 2 are connected by a synchronous linkage. By adding an additional bending control component for auxiliary operation, the user can choose to use it according to their own hand shape or operating habits, allowing the user to operate the rocker arm more comfortably and complete the bending operation of the endoscope.

The worm ring 11 is driven to rotate by rotating the worm 12, and the position of the ring-shaped rotating ring 9 and the worm ring 11 is locked by the worm 12 after the ring-shaped rotating ring 9 is rotated, so that the stability is improved.

[0027] As shown in Figure 2 and 3As shown, specifically, the first connecting rod 8 and the second connecting rod 10 each comprise a sleeve body and a connecting rod body, the connecting rod body of the first connecting rod 8 is fixedly connected with the U-shaped connecting piece 7 outside the additional bending control rocker 5, the sleeve body of the first connecting rod 8 is fixedly connected with the U-shaped connecting piece 7 outside the main bending control rocker 2, the sleeve body of the second connecting rod 10 is fixedly connected with the annular rotating ring 9, the connecting rod body of the second connecting rod 10 is fixedly connected with the rotating seat 3, the connecting rod body is slidingly connected inside the sleeve body, and the sleeve body is threadedly connected with a locking screw 13. Through the improvement of the structures of the first connecting rod 8 and the second connecting rod 10, the lengths of the first connecting rod 8 and the second connecting rod 10 can be adjusted according to the needs of users, when the lengths of the first connecting rod 8 and the second connecting rod 10 are adjusted, the position of the additional bending control rocker 5 is correspondingly adjusted, so that the position of the additional bending control rocker 5 is better adapted to the user.

[0028] In order to facilitate operation, the rear end of the main bending control rocker 2 is provided with a main pressing disc 14, and the rear end of the additional bending control rocker 5 is provided with an additional pressing disc 15. Through the arrangement of the main pressing disc 14 and the additional pressing disc 15, the contact area of the thumb of the user and the rocker can be increased, and operation is facilitated.

[0029] In order to facilitate operation, the rear end of the main bending control rocker 2 is provided with a main pressing disc 14, and the rear end of the additional bending control rocker 5 is provided with an additional pressing disc 15. Through the arrangement of the main pressing disc 14 and the additional pressing disc 15, the contact area of the thumb of the user and the rocker can be increased, and operation is facilitated.
