[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example, see Figure 1-5 A snake bone device for an endoscope, the snake bone operating part consists of a operating end, a snake bone bending end and a display end, the snake bone bending end consists of an outer snake bone layer and an inner flexible metal layer 1 sleeved inside the outer snake bone layer, the inner flexible metal layer 1 is in a hollow tubular shape, and is formed by metal weaving.

[0024] The outer snake bone layer is composed of a plurality of snake bone nodes 2, and adjacent snake bone nodes 2 are connected to each other through an inner flexible metal layer 1 sleeved therein;

[0025] The snake bone joint 2 is provided by a circular disk, and the two opposite sides of the circular disk are provided with inclined grooves, so that the snake bone joint 2 can be bent at the groove position.

[0026] By setting the bent end of the snake bone into an internal flexible metal layer 1 and an external snake bone layer sleeved on the outside of the inner flexible metal layer 1, bidirectional bending can be achieved through the wire control inside the external snake bone node 2, and the bending angle can be guaranteed to be consistent. In addition, the unique structure of the external snake bone node 2 can effectively avoid the entrapment of foreign objects, making it convenient to clean and disinfect the endoscope after surgery.

[0027] The display end includes a display contact 3 fixedly connected to the front end of the snake-bone bending end, an endoscope is arranged inside the display contact 3, and the wire of the endoscope is arranged through the inner flexible metal layer 1;

[0028] The operating end includes an operating disk 4 arranged at the tail end of the snake bone bending end, a central control tube 5 is arranged on the operating disk 4, a pressing operating plate 6 is rotatably arranged on the central control tube 5, further, the pressing operating plate 6 is sleeved on the central control tube 5, and rotating shafts 10 connected to the pressing operating plate 6 are arranged on both sides of the central control tube 5.

[0029] By setting the pressing control plate 6 on the central control tube 5 in a rotating manner with the rotating shaft 10, the traction columns 8 set on both sides of the pressing control plate 6 can be controlled to move up and down by pressing (seesaw principle), and in the process of moving up and down, the effect of controlling the wire control is achieved;

[0030] A wire control unit for controlling the movement of multiple snake bone nodes 2 is provided at the bottom of the pressing operation panel 6. The wire control unit includes traction through holes 7 relatively opened on both sides of the inside of the snake bone nodes 2. A traction column 8 is provided at the bottom of the pressing operation panel 6. A traction wire 9 is provided in the traction through hole 7. One end of the traction wire 9 is connected to the traction column 8, and the other end of the traction wire 9 is connected to the display contact 3.

[0031] It is worth noting that under the action of the wire control, when the traction force applied to the traction wire 9 on both sides is the same, it can ensure that the curved end of the snake bone composed of multiple snake bone nodes 2 is in a vertical state. When the traction force on one side increases, the traction force on the other side will decrease. At this time, the side with increased traction will cause the snake bone node 2 to be subjected to force, causing the snake bone node 2 to deflect toward the side where the traction force is applied, thereby achieving the effect of controlling the rotation angle.

[0032] A return spring is arranged on one side of the traction column 8, and the two ends of the return spring are respectively connected to the operating disk 4 and the pressing operating plate 6. The setting of the return spring can ensure that the curved end of the snake bone is in a vertical state without being affected by external forces.

[0033] By setting the snake bone device as a two-way control structure, when adjusting the angle, it is only necessary to control the rotation of the snake bone device and the pressing control of the pressing control plate 6. This can not only accurately control the bending angle of the endoscope, facilitate operation, but also ensure the accuracy of the rotation angle.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
