Problems solved by technology

The existing snake bone is generally composed of the front segment ring of the snake bone, several snake bone joints and the rear segment ring of the snake bone in sequence; The inner wall constitutes the perforation for threading the steel wire; currently, the center line of the two arc-shaped baffles and the center line of the two rivets of the snake joint are perpendicular to each other, which results in a poor distribution in the limited space of the snake joint Set the illumination fiber, image fiber and clamp tube
In addition, the existing snake bone has a small curvature, which is not conducive to surgical operation

Embodiment Construction

[0020] Such as Figure 1~3 As shown, the present invention provides a snake bone of an endoscope, which includes an anterior segment ring 1 of the snake bone, a plurality of snake bone segments 2 and a rear segment ring 3 of the snake bone riveted by rivets 5 in sequence, and the two side edges 7 of each snake segment It is a concave arc, so that there is an angle θ between the edges of two adjacent snake joints; combined with Figure 4 As shown, the two arc-shaped wire retaining plates 8 of the snake joint are used to pass through the steel wires 4 respectively, and the center line of the two arc-shaped wire retaining plates 8 in each snake joint and the center line of the two connecting ears 6 are in the shape of The included angle is 80-90°; it is convenient to reasonably distribute the first lighting fiber 9, the second lighting fiber 10, the image transmission fiber 11 and the clamping tube 12, reduce the extrusion between the optical fiber and the clamping tube, and exte...

Abstract

The invention discloses a snake bone of an endoscope. The snake bone comprises a front-section ring of the snake bone, a plurality of snake-bone joints and a rear-section ring of the snake bone which are sequentially in rivet joint with one another; the edges of the two sides of each snake-bone joint is in concave arc shapes to make an included angle formed between the edges of the two adjacent snake-bone joints; an included angle of 80-90 degrees is formed between the central connecting line of two arc line stopping plates and the central connecting line of two connecting lugs in each snake-bone joint; an included angle is formed between the edges of every two adjacent snake-bone joints, so that the bending degree between the two adjacent snake-bone joints can be increased, and the bending angle of the whole snake bone is increased; meanwhile, optical fibers for lighting, optical fibers for image transmitting and clamping tubes are conveniently and reasonably distributed, the extrusion between the optical fibers for image transmission and the clamping tubes is reduced, and the service life of the optical fibers for image transmission and the cavity clamping tubes is prolonged.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope snake bone. Background technique [0002] Endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. The endoscope can be used to see lesions that cannot be seen on X-rays, so it is very useful for doctors. [0003] When the existing endoscope realizes head bending and changing direction at a bending angle, the built-in snake bone bends it by pulling the steel wire rope connected with the snake bone. The existing snake bone is generally composed of the front segment ring of the snake bone, several snake bone joints and the rear segment ring of the snake bone in sequence; The inner wall constitutes the perforation for threading the steel wire; currently, the center line of the two arc-shaped baffles and the center line of the two rivets of the snake joint are per...
