Abstract

The utility model relates to the field of endoscope design, in particular to an integrated rivet endoscope snake bone, which comprises a plurality of snake bone units connected with each other, wherein the snake bone units are tubular, pipe orifices between the snake bone units are relatively connected in series into a whole, the pipe orifice walls at two ends of the snake bone units are respectively provided with an ear plate, the middle parts of the ear plates are provided with through holes, the ear plates between two adjacent snake bone units are superposed together and connected with each other through a rivet at the superposed through holes, the rivet comprises a rivet rod and a rivet cap, a threading hole is arranged in the rivet cap, the rivet cap is arranged in the pipe of the snake bone units, the application adopts an integrated rivet, namely, the rivet not only plays a connecting role, but also is provided with a threading hole for a steel wire rope to pass through, the steel wire rope plays a role of guiding the direction of the snake bone in the snake bone, no small steel pipe is needed to be welded additionally, and the inner space of the snake, when the same steel wire rope is used, the external size of the snake bone can be reduced, and the design concept of miniaturization of the snake bone is met.

Description

Integrated rivet endoscope snake bone

Technical Field

The utility model relates to an endoscope design field especially relates to an integration rivet endoscope snake bone.

Background

The miniature image pickup of the medical human body endoscope is a mode for realizing the visual target of the health condition of tissues and organs in the human body in the field of medical diagnosis and treatment, and the safety and the comfort of the endoscopy are the requirements and the directions of patients. The snake bone is miniaturized, and the comfort level of the human body can be enhanced. The snake bone internal space also needs installation parts, the external dimension of the snake bone is reduced, the internal space is enlarged, and the goal trend of the optimization and improvement of the snake bone design is. Among the prior art, the snake bone is formed by concatenating a plurality of units, and it is fixed to adopt rivet connection's mode usually between each unit, and the inside little steel pipe that can weld of snake bone usually comes the confession steel wire to pass with control snake bone direction of motion, but the design of little steel pipe is more occupation space for the external dimension of whole snake bone is great, is not conform to the design theory that the snake bone is miniaturized.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defect that above-mentioned prior art exists, provide an integration rivet endoscope snake bone, can save snake bone inner space.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an integration rivet endoscope snake bone, include a plurality of snake bone units that link to each other, the snake bone unit is the tubulose, the mouth of pipe is established ties relatively between the snake bone unit integratively, all set up the otic placode on the both ends mouth of pipe wall of snake bone unit, the through-hole is seted up at the otic placode middle part, otic placode stack between two adjacent snake bone units is in the same place and realize the connection of snake bone unit through the rivet in superimposed through-hole department, the rivet includes rivet stem and rivet cap, set up the wire rope handling hole in the rivet cap, the inside at the snake bone unit is arranged to the rivet cap.

The number of the ear plates on the pipe orifice wall of each end of the snake bone unit is two, and a connecting line between the two ear plates on the pipe orifice wall of one end is vertical to a connecting line between the two ear plates on the pipe orifice wall of the other end.

The central line of the rope threading hole is parallel to the pipe central line of the snake bone unit.

The ear plate is extended in a direction of a tube length of the snake bone unit.

Has the advantages that: this application adopts the integral type rivet, and the rivet both plays the connection effect promptly, sets up the wire rope handling hole that supplies wire rope to pass again in the rivet cap, and wire rope plays the effect of guide snake bone direction in the snake bone is inside, need not to weld little steel pipe in addition again, has saved snake bone inner space greatly, can reduce snake bone external dimension when using the same wire rope, accords with the design theory that the snake bone is miniaturized.

Detailed Description

The invention will be further described with reference to fig. 1-2.

The utility model provides an integration rivet endoscope snake bone, including a plurality of snake bone units 10 that link to each other, snake bone unit 10 is the tubulose, the mouth of pipe is relative to establishing ties integratively between snake bone unit 10, all set up otic placode 11 on the both ends mouth of pipe wall of snake bone unit 10, the through-hole is seted up at otic placode 11 middle part, otic placode 11 stack between two adjacent snake bone units 10 is in the same place and realize the connection of snake bone unit 10 through rivet 20 in superimposed through-hole department, rivet 20 includes rivet bar 21 and rivet cap 22, set up stringing hole 23 in rivet cap 22, rivet cap 22 arranges the inside at snake bone unit 10. This application adopts integral type rivet 20, and rivet 20 both plays the connection effect promptly, sets up the wire rope handling hole 23 that supplies wire rope to pass in rivet cap 22 again, and wire rope plays the effect of guide snake bone direction in the snake bone is inside, need not to weld little steel pipe in addition again, has saved snake bone inner space greatly, can reduce snake bone external dimension when using the same wire rope, accords with the design theory that the snake bone is miniaturized.

Preferably, the number of the ear plates 11 on each end of the pipe orifice wall of the snake bone unit 10 is two, wherein the connecting line between the two ear plates 11 on one end of the pipe orifice wall is perpendicular to the connecting line between the two ear plates 11 on the other end of the pipe orifice wall. The ear plates 11 are uniformly distributed, so that the connection between the snake bone units 10 is more stable.

Further, the center line of the rope threading hole 23 is parallel to the pipe center line of the snake bone unit 10, so as to ensure that the steel wire rope smoothly passes through the rope threading hole 23.

Furthermore, the ear plates 11 are extended in the direction of the tube length of the snake bone unit 10 to ensure the relative connection of the tube openings between the snake bone units 10.

It should be understood that the above description of the specific embodiments is only for the purpose of explanation and not for the purpose of limitation. Obvious changes or variations caused by the spirit of the present invention are within the scope of the present invention.
