Abstract

A steering structure of an endoscope comprises a photographic lens group, a front pin joint member, traction steel wires, a front joint ring, multiple middle joint rings, an elastic element, a flexible sleeve, a rear joint ring, a rear pin joint member and a flexible coiler element. When any one of the traction steel wires is tightly pulled, the opposite traction steel wire is loosened at the same time, and the elastic element and the flexible sleeve are enabled to move crookedly in the tightened direction with a maximal angle of bending almost capable of enabling the imaging direction of the photographic lens group to be parallel to a signal transmission line. The angle of an observation angle of the photographic lens group is determined by the tension amplitude of the traction steel wires. As such, the endoscopy detection can be carried out safely in detail. The arbitrary rotation four-direction steering structure of the photographic lens group is composed of the multiple middle joint rings and the elastic element which are simple in structure, and thus a cheap steering structure of the endoscope is provided to help effectively reduce cost and improve economic performance.

Description

Introscope turn to structure

Technical field

The utility model is the structure that turns to of relevant a kind of introscope, detailed it, refer to the pliability structural improvement that a kind of phtographic lens group can be rotated toward four direction especially, and then reach cheap design.

Background technology

Because developing rapidly of optical image and electronic correlation science and technology, present endoscope apparatus, its structure mostly is by camera module, light-emitting component and a hollow tube are formed by connecting, connect the image that display screen can display-object thing inside again, be used in various fields widely, national defence for example, medical science, industrial and commercial, fishing is herded, agricultural, education etc., wherein the utilization aspect medical is also quite general, watched the tissue of life entity inside such as the endoscope apparatus that is used in medical application, or the endoscope apparatus that is used in industrial use is watched machinery, the structure of car engine inside allows the operator obtain to detect object and has or not abnormal case.

But, the introscope of prior art turns to warp architecture a lot of, such as: the novel M384635 of TaiWan, China, M414932 and M417129 patent etc. disclose three kinds of different bend pipe steering structures, but those patents need just to be controlled introscope work 360 degree by the rotation grip part to be turned to, so, need experienced operator just to be operated this introscope flexibly.

And for example, the novel M400299 patent of TaiWan, China disclose to borrow the pulling control line to reach the structure that the control introscope is done 360 degree motions, improving the above-mentioned shortcoming that needs to rotate the grip part, and can supply the operator intuitively adjust angle according to the angle of bending.

But the introscope steering mechanism of above-mentioned prior art, the fine structure and the spare part that all have numerous complicated can turn to for keeping metal construction, therefore must possess quite high precision, certainly will cause production cost significantly to increase, and job sequence is more numb numerous, trifling.

Because every problem of above-mentioned existing skill, in order to take into account solution, the inventor is based on researching and developing for many years and practical experience, and go through repeatedly the road of repetition test, research improvement, conclusive evidence is developed a kind of structure that turns to of introscope, can fully satisfy intended purposes, effect, with the implementation foundation of improving as the problems referred to above.
