[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0037] Figures 1 to 7 An embodiment of the present application provides a snake bone assembly 100. The snake bone assembly 100 is a part of an endoscope device.

[0038] The two adjacent snake bone joints 10 are respectively 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 are connected to each other and can move relative to each other, so as to adjust the position of the first snake bone joint 11 relative to the second snake bone joint 12; the first snake bone joint 11 is provided with a first connecting part 111 and a first inner cavity 11a; the second snake bone joint 12 is provided with a second connecting part 121 and a second inner cavity 12a; the second inner cavity 12a is connected to the first inner cavity 11a along the length direction of the snake bone component 100; the second connecting part 121 is connected to the first connecting part 111 and moves with each other. The connection structure between the second connecting part 121 and the first connecting part 111 is at least one of a hinged structure, a spherical movable structure and an arc-shaped movable structure, so as to facilitate the movement of the first snake bone joint 11 and the second snake bone joint 12, thereby ensuring the flexibility between the first snake bone joint 11 and the second snake bone joint 12, avoiding the use of metal joints for movement, and then realizing the flexible movement of the snake bone component 100, thereby improving the flexibility of the snake bone component 100.

[0039] The snake bone assembly 100 also includes a connecting rope 20, which is passed through the first snake bone joint 11 and the second snake bone joint 12 along the length direction of the snake bone assembly 100. The first snake bone joint 11 and the second snake bone joint 12 are arranged relatively to each other, so that the first snake bone joint 11 and the second snake bone joint 12 can be connected through the connecting rope 20, thereby ensuring the position between 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 12 are plastic parts, metal parts or a mixture of plastic and metal parts.

At this time, the first serpentine joint 11 and the second serpentine joint 12 are movably connected. The multiple connecting ropes 20 pass through and connect the first serpentine joint 11 and the second serpentine joint 12. As the direction of the connecting ropes 20 is controlled, the movement between the first serpentine joint 11 and the second serpentine joint 12 is driven, thereby controlling the movement direction of the first serpentine joint 11 and the second serpentine joint 12. At this time, the connecting ropes 20 are slender steel wire ropes, which are not limited here.

[0044] In the second embodiment, when the connection structure between the second connection part 121 and the first connection part 111 is a spherical movable structure, the first connection part 111 is provided with a first spherical end 1111, and the first spherical end 1111 is inserted into the second connection part 121 and spherically connected to the second connection part 121, so that the first connection part 111 is spherically connected to the second connection part 121 through the first spherical end 1111, thereby facilitating the movement of the first serpentine joint 11 and the second serpentine joint 12, thereby ensuring the flexibility between the first serpentine joint 11 and the second serpentine joint 12, avoiding the use of metal joints for movement, thereby realizing the flexible movement of the serpentine assembly 100, and improving the flexibility of the serpentine assembly 100.

[0045] The second connecting part 121 is provided with a first spherical hole 121b, and the first spherical end 1111 is inserted into the first spherical hole 121b and spherically connected to the first spherical hole 121b to realize that the second connecting part 121 and the first connecting part 111 are a spherical movable structure. There is a gap between the outer contour of the first spherical end 1111 and the inner contour of the first spherical hole 121b, so that the second connecting part 121 can move relative to the first connecting part 111 through the first spherical hole 121b and the first spherical end 1111.

[0046] The first connecting portion 111 is provided with a tapered portion 1112, which is arranged in the vertical direction. The tapered portion 1112 is on one side of the first spherical end 1111, and the smaller end of the tapered portion 1112 is connected to the first spherical end 1111, so that the first connecting portion 111 can realize the existence of movable space with the second connecting portion 121 in the upper and lower directions through the tapered portion 1112, thereby facilitating the movement of the first serpentine joint 11 and the second serpentine joint 12, thereby ensuring the flexibility between the first serpentine joint 11 and the second serpentine joint 12, avoiding the use of metal joints for movement, thereby realizing the flexible movement of the serpentine assembly 100, and improving the flexibility of the serpentine assembly 100.

[0047] In the third embodiment, when the connection structure between the second connection part 121 and the first connection part 111 is an arc-shaped movable structure, the first connection part 111 is provided with a first arc part 1113, and the second connection part 121 is provided with a second arc part 1212, and the second arc part 1212 is plugged into the first arc part 1113; the bottom of the first connection part 111 is provided with an arc hole 111b, and the second arc part 1212 can be movably plugged into the arc hole 111b, so that the first connection part 111 can realize an arc-shaped movable connection with the second connection part 121 through the second arc part 1212 and the arc hole 111b, thereby facilitating the movement of the first serpentine joint 11 and the second serpentine joint 12, thereby ensuring the flexibility between the first serpentine joint 11 and the second serpentine joint 12, avoiding the use of metal joints for movement, thereby realizing the flexible movement of the serpentine component 100, and improving the flexibility of the serpentine component 100.
