Figures 1-7 In this embodiment of the application, the snake bone device 100 includes a plurality of snake bone joints 10, which are connected end to end along the length direction of the snake bone device 100; by arranging a plurality of snake bone joints 10, the overall length of the snake bone device 100 is increased, thereby increasing the swing angle of the overall snake bone device 100.

[0041] Please refer to the attached document. Figures 1-7The two adjacent snake joints 10 are the first snake joint 11 and the second snake joint 12, respectively; the second snake joint 12 is swayably connected to the first snake joint 11 and sways relative to the first snake joint 11; so as to adjust the position of the second snake joint 12 relative to the first snake joint 11.

[0042] Please refer to the attached document. Figures 1-5 The first snake joint 11 is provided with an arc groove 11a; the second snake joint 12 is provided with a swing arm 121. The arc groove 11a and the swing arm 121 are arranged opposite to each other. The inner contour of the arc groove 11a is adapted to the outer contour of the swing arm 121. The swing arm 121 is built into the arc groove 11a and moves along the arc direction of the arc groove 11a. There is a movable gap between the outer side wall of the swing arm 121 and the inner side wall of the arc groove 11a. By cooperating with the arc groove 11a, the swing range between the first snake joint 11 and the second snake joint 12 is increased, avoiding the limitation of the swing range between the second snake joint 12 and the first snake joint 11, and improving the swing range of the snake device 100. Optionally, the two opposing side walls between the swing arm 121 and the arc groove 11a are arranged at an inclination, and the two opposing side walls between the swing arm 121 and the arc groove 11a have a height difference, so as to prevent the swing arm 121 from separating from the arc groove 11a and ensure the connection stability between the swing arm 121 and the arc groove 11a during the movement.

[0043] Please refer to the attached document. Figures 1-5 In this embodiment, the second snake-bone joint 12 is provided with a rotating hole 12a; the first snake-bone joint 11 is provided with a rotating support arm 111, and an arcuate groove 11a is provided on the outer side of the rotating support arm 111; the rotating support arm 111 is located within the rotating hole 12a and rotates along the axis of the rotating hole 12a, so as to increase the connection strength between the second snake-bone joint 12 and the first snake-bone joint 11 through the cooperation of the rotating hole 12a and the rotating support arm 111, thus ensuring the connection stability between the second snake-bone joint 12 and the first snake-bone joint 11. At the same time, it improves the swing stability between the second snake-bone joint 12 and the first snake-bone joint 11.

[0044] Optionally, the two opposing side walls between the rotating support arm 111 and the rotating hole 12a are arranged at an inclination, and there is a height difference between the two opposing side walls between the rotating support arm 111 and the rotating hole 12a to prevent the rotating support arm 111 from separating from the rotating hole 12a.

[0045] Please refer to the attached document. Figures 1-7In this embodiment, the rotating hole 12a is a circular hole; one end of the rotating support arm 111 is a circular end and is adapted to the rotating hole 12a so that the inner contour of the rotating hole 12a is adapted to the outer contour of the rotating support arm 111, so that the rotating support arm 111 can rotate along the axis of the rotating hole 12a, thereby facilitating the second snake joint 12 to swing relative to the first snake joint 11 along the axis of the rotating hole 12a, and ensuring the swing stability between the second snake joint 12 and the first snake joint 11.

[0046] Please refer to the attached document. Figures 1-7 In this embodiment, multiple swing arms 121 are arranged opposite to each other and enclose a rotating hole 12a. This allows the space between the multiple swing arms 121 to form the rotating hole 12a, thus facilitating the inner sidewalls of the multiple swing arms 121 to serve as the inner contour of the rotating hole 12a. Specifically, two swing arms 121 are arranged opposite to each other, enclosing the rotating hole 12a. The rotating hole 12a is formed through the space between the two swing arms 121, allowing the swing arms 121 to be housed within the rotating hole 12a, facilitating rotation through the interaction between the swing arms 121 and the rotating hole 12a. Optionally, the swing arm 121 is an arc-shaped arm.

[0047] Please refer to the attached document. Figures 1-7 In this embodiment, a movable groove 11b is provided between the first snake-bone joint 11 and the second snake-bone joint 12. The first snake-bone joint 11 and the second snake-bone joint 12 can swing relative to each other through the movable groove 11b, thereby facilitating the adjustment of the position between the first snake-bone joint 11 and the second snake-bone joint 12 and expanding the swing range of the first snake-bone joint 11 and the second snake-bone joint 12. Optionally, the first snake-bone joint 11 and the second snake-bone joint can be cut from a round tube, and the movable groove 11b or the movable gap between the first snake-bone joint 11 and the second snake-bone joint can be used as the cut part.

[0048] Please refer to the attached document. Figures 2-7 In the snake bone device 100, there are multiple movable slots 11b. The multiple movable slots 11b are arranged at intervals along the length direction of the snake bone device 100. By arranging multiple movable slots 11b, the multiple snake bone joints 10 can all move, ensuring that the snake bone joints 10 in the snake bone device 100 can all swing.

[0049] Please refer to the attached document. Figures 2-7 In this embodiment, two adjacent movable slots 11b are staggered along the length of the snake bone device 100 so that multiple snake bone joints 10 can swing relative to each other in the front-back and left-right directions, thereby facilitating the movement of multiple snake bone joints 10 in multiple directions and improving the flexibility of the snake bone device 100.

[0050] Please refer to the attached document. Figures 2-7 In this embodiment, the second snake-bone joint 12 is provided with a groove 12b, which connects to the movable groove 11b. This allows the swing range between the first snake-bone joint 11 and the second snake-bone joint 12 to be further expanded through the space of the groove 12b. This facilitates the swinging of the first snake-bone joint 11 and the second snake-bone joint 12 relative to the space between the groove 12b and the movable groove 11b, further improving the swing range of the snake-bone device 100. Optionally, the groove 12b is arranged in a straight line.

For example, the endoscopic device can highlight lesions and fine structures of blood vessels formed in the mucosal or submucosal layer.

[0052] At this time, the snake bone device 100 includes multiple snake bone joints 10, which are connected end to end along the length of the snake bone device 100; two adjacent snake bone joints 10 are respectively a first snake bone joint 11 and a second snake bone joint 12; the second snake bone joint 12 is swayably connected to the first snake bone joint 11 and sways relative to the first snake bone joint 11; the first snake bone joint 11 is provided with an arc groove 11a; the second snake bone joint 12 is provided with a swing arm 121, which is built into the arc groove 11a and moves along the arc direction of the arc groove 11a. There is a movable gap between the outer side wall of the swing arm 121 and the inner side wall of the arc groove 11a. By cooperating with the arc groove 11a, the swing range between the first snake bone joint 11 and the second snake bone joint 12 is increased, avoiding the limitation of the swing range between the second snake bone joint 12 and the first snake bone joint 11, and improving the swing range of the snake bone device 100.
