Description
Technical field
The present invention relates to a kind of viewing instruments, particularly relate to a kind of endoscope swan-neck.
Background technology
Endoscope generally comprises first end and skeleton, is provided with the parts such as camera lens, light source in first end, utilizes can control first end through intraskeletal angle steel wire and carry out bending turning to.If publication number is disclose a kind of curved part of endoscope in the Chinese patent of CN102497801B, this curved part of endoscope comprises multiple joint ring 28a and 28b, adjacent protrusion-type joint ring 28a and pass save ring 28b, protrusion-type tongue piece portion 31a is overlapping to radial outside from radially inner side with pass tongue piece portion 31b, and the jut 32 of protrusion-type tongue piece portion 31a is inserted in the hole portion 33 of pass tongue piece portion 31b.Jut 32 can rotate in hole portion 33 centered by the central axis of jut 32.Because of the rotation of this jut 32 in hole portion 33, protrusion-type tongue piece portion 31a and pass tongue piece portion 31b rotates mutually, and protrusion-type joint ring 28a and pass save ring 28b and mutually rotate.At this, about protrusion-type joint ring 28a, a pair protrusion-type tongue piece portion 31a of tip side, base end side is configured in left and right, upper and lower position respectively, and about pass tongue piece portion 31b, a pair pass tongue piece portion 31b of tip side, base end side is configured in up and down respectively, the position of left and right.Therefore, for predetermined protrusion-type joint ring 28a, the pass joint ring 28b of tip side, base end side can distinguish along the vertical direction, left and right directions rotates, in addition, for predetermined pass joint ring 28b, the protrusion-type joint ring 28a of tip side, base end side can distinguish in left-right direction, above-below direction rotates, and swan-neck entirety can vertically bend by left and right directions.But just can become bending section, its complex structure after joint ring 28a with 28b is connected by this structure needs successively, the work needing staff to pay high strength could realize, and its number of components is many, the same high enterprise of cost of manufacture.In addition, because sweep diameter is very little, so to arrange can be a difficult thing equally installing the component in bending first end.
And for example publication number is that the Chinese patent of CN102858227B discloses a kind of endoscope, this endoscope has: initiatively bending section 11, it is arranged in insertion section, connected to by multiple turning cylinder 35a, 35b between adjacent curved block 11a and rotate freely, each turning cylinder 35a, 35b differ 90 ° on the circumferencial direction J of curved block 11a, and this active bending section 11 bends freely according to bending operation; And passive bending section 13, it is arranged on than active bending section 11 more by base end side, connected to by multiple turning cylinder 45a ~ 45c between adjacent curved block 13a and rotate freely, each turning cylinder 45a ~ 45c differs 60 ° on circumferencial direction J, can passively freely bend when this passive bending section 13 is subject to external force.Similarly, this curvature section of endoscope is formed by connecting by multiple curved block 11a equally, and its structure is complicated equally, and the work also needing staff to pay high strength could realize, and its number of components is many, the same high enterprise of cost of manufacture.There is the problem that intraware installs difficulty equally in this bending section.
And for example publication number is that the Chinese patent application of CN104023616A discloses a kind of endoscope-use swan-neck, this endoscope-use swan-neck comprises: the multiple 1st bending uses slit 33a, its length axes O direction along the swan-neck main body 31 of cylindrical shape is arranged every setting compartment of terrain, and extends in the circumference of this swan-neck main body 31.Although the swan-neck disclosed in the document is integral type, there is processing difficulties similarly, internals installs the problem of difficulty.
Summary of the invention
