Problems solved by technology

[0004] Because the snake bone parts are very fine and small, not only the molding process is complicated, but also the assembly process requires a lot of time and labor costs. It needs to be assembled manually by professional technicians, and the yield rate is not easy to guarantee. The superposition of these processes will undoubtedly greatly increase Total Cost of Snake Bone
[0005] In addition, at this stage, traditional flexible endoscopes are expensive and must be reused in clinical applications. However, due to the manufacturing process, they cannot be sterilized and can only be disinfected and cleaned, and the disinfection method is single. The risk of cross-infection among patients is extremely high
If the tube endoscope can be used once, it will completely solve the problem of cross-infection caused by the repeated use of traditional endoscopes, and the snake bone is an indispensable part of the tube endoscope, and its cost is directly related to Whether the hose endoscope can be used at one time, so it is necessary to seek a low-cost snake bone
[0006] Although some elastic snake bone components made of polymer materials have appeared to deal with the problem of high cost of riveted structures, such materials themselves have the defect of limited service life and are prone to failure

Embodiment 1

[0050] Such as figure 1 and Picture 1-1 As shown, a double-encircled rotating structure includes a female rotating part 1 and a sub rotating part 2,

[0051] The female rotating part 1 includes a circular protrusion 1-1, an inner surrounding annular groove 1-2 arranged around the circular raised part, and an outer surrounding annular protrusion arranged around the inner surrounding annular groove 1-2. Starting part 1-3;

[0052] The sub-rotating part 2 includes an inner ring-shaped raised portion 2-1 for surrounding the circular raised portion 1-1 and an outer ring-shaped groove arranged around the inner ring-shaped raised portion 2-1. 2-2;

[0053] The inner ring-encircling protruding part 2-1 of the sub-rotating part 2 is arranged in the inner ring-encircling groove 1-2 of the female rotating part 1, and the outer encircling ring-shaped protruding part 1-3 of the female rotating part 1 It is arranged in the outer ring-shaped groove 2-2 of the sub-rotating part 2, and ma...

Embodiment 2

[0057] Such as diagram 2-1 , Figure 2-2 and figure 1 As shown, the difference between this embodiment and Embodiment 1 is: a double-encircling pipe body rotation structure, including two pipe bodies 3, and the circumferential sides of the connecting ends of the two pipe bodies 3 respectively pass through the double pipe body. The embracing and rotating structure is connected, and the rotation axes of the double embracing and rotating structures on both sides are coaxially arranged. Specifically, two female rotating parts 1 are respectively located on both sides of the connecting end of one of the pipes, and two female rotating parts 1 are formed on both sides of the connecting end of the other pipe. There are two sub-rotating parts 2 on both sides, and the other two sides in the circumferential direction of the connecting ends of the pipe body 3 in the two sections respectively have an axial opening 4;

[0058] The axial openings 4 of the two sections of the tube body 3 re...

Embodiment 3

[0063] Such as image 3 As shown, the difference between this embodiment and embodiment 2 is: an integrated tubular body rotating structure, which includes the double-encircling tubular body rotating structure,

[0064] The rotating contact surface of the female rotating part 1 and the sub rotating part 2 is a radial limit bevel 6, and the inclination directions of the radial limit bevels in the two double-encircling tubular body rotating structures on both sides are opposite, so that To prevent radial disengagement of the pipe body 3 described in the two sections, due to the adoption of an integrated structure, the integrated structure is formed at one time without assembly process, which saves the production process, reduces time cost and labor cost.

[0065] Principle: During the cutting process, the laser cutting beam always points to the center of the pipe body, and every slit on the circumference has an angle. As long as the thickness of the stainless steel pipe wall is ...

Abstract

The invention provides a double-surrounding rotating structure. The double-surrounding rotating structure comprises a primary rotating portion and a secondary rotating portion, wherein the primary rotating portion comprises a circular projection portion, an inner-surrounding annular groove and an outer-surrounding annular projection portion; the secondary rotating portion comprises an inner-surrounding annular projection portion and an outer-surrounding annular groove; the inner-surrounding annular projection portion is arranged in the inner-surrounding annular groove; the outer-surrounding annular projection portion is arranged in the outer-surrounding annular groove, so that the primary rotating portion and the secondary rotating portion can rotate relatively; and the surrounding rotating structure cannot be separated due to multiple limiting structures. According to a double-surrounding tube rotating structure based on this, a rotating travel crack is formed in a relative rotating side, and thus, tubes rotate relatively and are not separated in the axial direction. Furthermore, an integrated tube rotating structure based on the structure is designed, rotating contact surfaces ofthe primary and secondary rotating portions are or comprise radial limiting oblique surfaces, and thus, the two tubes cannot be separated from each other in the radial direction. Finally, a snake bone for a medical endoscope and an endoscope are further provided on the basis of the design, and have the advantages of high stability and low cost.

Description

technical field [0001] The invention relates to an encircling rotating structure, and also relates to a double encircling tubular body rotating structure based on the encircling rotating structure, an integrated tubular rotating structure, a medical endoscope snake bone and an endoscope. Background technique [0002] Existing endoscopes realize bending and turning, and the operation is completed through a built-in snake bone and an operation wire connected to control the rotation of the snake bone, and the snake bone is composed of several joints hinged together. [0003] The snake bone usually includes the front end section of the snake bone, several middle sections of the snake bone and the rear end section of the snake bone, and they are riveted together by rivets. [0004] Because the snake bone parts are very fine and small, not only the molding process is complicated, but also the assembly process requires a lot of time and labor costs. It needs to be assembled manuall...
