[0002] Before the development of endoscope technology, the diagnosis of diseases of human internal organs and tissues often relied on external physical signs observation, laboratory tests, and some invasive and high-risk surgical exploration. The emergence of endoscopes, especially endoscopes with flexible snake bone structures, enables doctors to insert endoscopes into the human body through natural cavities (such as the oral cavity, nasal cavity, anus, etc.) or small incisions to directly observe the lesion sites, greatly improving the accuracy and timeliness of disease diagnosis. However, the existing endoscope snake bones cannot be bent at arbitrary angles, so there will be certain dead angles. To achieve full-range observation, the user needs to rotate the entire endoscope snake bone, which is relatively troublesome to operate and has poor accuracy.
[0003] Therefore, an endoscope snake bone with controllable bending degree is proposed for improvement to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an endoscope snake bone with controllable bending degree. In actual use, when the operator needs to adjust the direction of the endoscope body, by pulling two first wires, the endoscope body is tilted to one side, and at the same time, one end of the first snake bone is tilted as a whole, realizing the adjustment of the position and angle of the endoscope body. The rotational connection between the first support ring and the second support ring enables the corresponding adjustment of the angle and position during the bending and turning processes of the first snake bone and the second snake bone, so as to achieve the purpose of meeting the operation requirements of the endoscope.
[0005] To achieve the above purpose, the main technical solutions adopted by the utility model include:

[0024] The following will cooperate with the drawings and embodiments to detail the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.
[0025] As Figures 1-6As shown in the figure, the endoscope snake bone with controllable bending degree provided in this embodiment includes snake bone 1. One end of snake bone 1 is fixedly connected to the endoscope body 2. Snake bone 1 is an important component connecting the endoscope body 2 and subsequent structures. Its main function is to achieve the bending function, enabling the endoscope to flexibly change directions in complex environments and spaces and reach the target position for inspection or operation. The endoscope body 2 is used to collect image information of the inspected part and convert this information into signals for observation and analysis. On the side of the endoscope body 2 close to snake bone 1, a plurality of first wires 3 are fixedly connected. The plurality of first wires 3 are evenly distributed, and the number of first wires 3 is two. By using the first wires 3, the endoscope body 2 can be pulled to tilt, and then one end of snake bone 1 can be tilted to achieve the purpose of changing the direction. The end of snake bone 1 far from the endoscope body 2 is fixedly connected to snake bone 2 4. Snake bone 2 4 has a similar function to snake bone 1, both for achieving the bending and turning of the endoscope, further extending the reach range and operation flexibility of the endoscope. The other end of snake bone 2 4 is fixedly connected to support ring 1 5. Support ring 1 5 plays a role in connection and support. On the one hand, it connects snake bone 2 4 with other components. On the other hand, it provides certain support and stability for the entire structure, preventing the structure from deforming or being damaged during use. The other end of support ring 1 5 is rotatably connected to support ring 2 6. Through the rotational connection between support ring 2 6 and support ring 1 5, the components connected thereto can rotate relative to each other, further increasing the flexibility and operability of the endoscope during use.
[0026] Among them, as Figures 1-6 shown, snake bone 1 is made of stainless steel with spring properties, and snake bone 1 is integrally in the shape of a helical spring. Snake bone 1 made of stainless steel with spring properties and in the shape of a helical spring mainly functions to provide flexible bending and turning capabilities. Due to the use of stainless steel material with spring properties and the structure of a helical spring, snake bone 1 has good elasticity and deformation recovery ability, and can be bent and twisted within a certain range according to the operator's needs to change the direction and position of the front end of the endoscope and reach the target area for inspection or operation.
[0027] Further, as Figures 1-6As shown, a plurality of first limiting rings 7 are fixedly connected to the inner wall of the first snake bone 1. The plurality of first limiting rings 7 are evenly distributed on both sides of the inner wall of the first snake bone 1. The first lead 3 passes through the plurality of first limiting rings 7, and the first lead 3 is slidably connected to the first limiting rings 7. The first limiting rings 7 are evenly distributed on both sides of the inner wall of the first snake bone 1. The main function is to limit and guide the first lead 3. By being fixedly connected to the inner wall of the first snake bone 1, it provides a specific channel for the first lead 3, restricts the position of the first lead 3 within the first snake bone 1, and prevents it from moving or winding randomly. At the same time, since the first lead 3 is slidably connected to the first limiting rings 7, when the first snake bone 1 bends and rotates, the first lead 3 can slide relatively smoothly within the first limiting rings 7 without being overly stretched or squeezed.
[0028] Among them, as Figures 1-6 shown, the second snake bone 4 includes a plurality of bone joints 8. The plurality of bone joints 8 are all hinged to each other. The plurality of mutually hinged bone joints 8 together form the second snake bone 4. Its function is to enable the second snake bone 4 to have the ability to bend, so as to be able to adapt to different angle requirements in a specific environment or operation, facilitate the second snake bone 4 to cooperate with the first snake bone 1 to perform corresponding work, and at the same time the second snake bone 4 can support the first snake bone 1.
[0029] Among them, as Figures 1-6 shown, a plurality of connecting blocks 9 are fixedly connected to the inner wall of the first support ring 5. The number of the connecting blocks 9 is two. One side of each of the plurality of connecting blocks 9 is fixedly connected to a second lead 10. The connecting blocks 9 are fixed to the inner wall of the first support ring 5 and are used to connect and fix the second lead 10, providing a fixed point for the second lead 10 to ensure a stable connection of the second lead 10 inside the first support ring 5. A plurality of second limiting rings 11 are fixedly connected to the inner wall of the first support ring 5. The second lead 10 passes through the second limiting rings 11, and the second lead 10 is slidably connected to the second limiting rings 11. The second limiting rings 11 are fixed to the inner wall of the first support ring 5, which play a role in limiting and guiding the second lead 10, ensuring the stable position of the second lead 10 inside the first support ring 5, and allowing the second lead 10 to slide relatively smoothly when the first support ring 5 moves or rotates, avoiding the second lead 10 from being overly bent, wound, or subjected to unnecessary stretching and squeezing.
[0030] Furthermore, as Figures 1-6 shown, a rotating rod 12 is rotatably connected to the side of the first support ring 5 close to the first lead 3. The second lead 10 is rotatably connected to the rotating rod 12. The main function of the rotating rod 12 is to reduce friction and better drive the rotation of the first support ring 5 when pulling the second lead 10. It enables the second lead 10 to adjust its position and posture through the rotational connection with the rotating rod 12 when the first support ring 5 rotates or changes its position, avoiding the second lead 10 from being overly twisted, stretched, or damaged due to the movement of the first support ring 5, and ensuring the normal function and service life of the second lead 10.
[0031] Among them, as Figures 1-6 shown, on the side of the second support ring 6 away from the first support ring 5, a plurality of third limiting rings 13 are fixedly connected. A plurality of first wires 3 and a plurality of second wires 10 both penetrate through the plurality of third limiting rings 13. The third limiting rings 13 are fixedly connected to the side of the second support ring 6 away from the first support ring 5. Its main function is to limit and fix the first wires 3 and the second wires 10, preventing the first wires 3 and the second wires 10 from having large displacements, entanglements or disorders during the operation of the device, and ensuring the regular arrangement of the wires.
[0032] As Figures 1-6 shown, the principle of the endoscope snake bone with controllable bending degree provided in this embodiment is as follows: In actual use, when the operator needs to adjust the direction of the endoscope body 2, by pulling the two first wires 3, the endoscope body 2 is tilted to one side, and at the same time, one end of the first snake bone 1 is tilted as a whole, realizing the adjustment of the position and angle of the endoscope body 2. The amount of pulling the first wire 3 determines the bending degree of the first snake bone 1. At the same time, by pulling the second wire 10, the second wire 10 moves outward through the rotating rod 12, so that the first support ring 5 rotates on the second support ring 6, so that during the bending and turning of the first snake bone 1 and the second snake bone 4, the angle and position can be correspondingly adjusted to achieve the purpose of adapting to the operation requirements of the endoscope.
[0033] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction.
