Description
Technical field
The utility model is related to endoscopic technique fields, and in particular, to a kind of focusing endoscope.
Background technology
Endoscope is a kind of precision instrument being combined into using fibre optics and optics, precision optical machinery and electronic technology,
There are extensive purposes and important function in national economy every field such as medical treatment, industry and military affairs.
When in use, the distance that whens different operating modes is observed object and endoscope head end is very different endoscope.
Sometimes point blank is needed to observe, need distant surveillance again sometimes.
The cephalic par of endoscope of the prior art, since the optical system built in it is setting, the depth of field is to fill
Timing is calibrated for different field depths, but the complete i.e. fixation of adjustment, it is impossible to become again, user can not change again when in use.
Therefore, presently mainly this is solved the problems, such as by optical technology, i.e. the design processing king-sized objective lens optical system of field depth
It goes to meet aforementioned need.But the technical solution has technological limit, and it is 2-100mm's that can design process field depth at present
Objective lens optical system, already close to the limit of current optical technology, the company of only a small number of international top levels could realize.
Therefore, cost is naturally also high.Moreover, field depth is bigger, the parameter that can not optically take into account is more, therefore picture quality
It can be sacrificed.
Also have a solution at present, such as the GE in the U.S., the OLYMPUS of Japan, China it is bright up to peeping in company
Mirror provides a kind of replacement head, different field depths is realized by replacing head, so as to meet the observation demand of different operating modes.
But must select correctly to replace head when using every time, otherwise endoscope from applying working condition must be extracted out, replaced
Row insertion observation again, very big inconvenience is brought to using after head.It is just more troublesome when first use runs into several different operating modes.And
And an endoscope needs the replacement head with different field depths, cost is also high.
Also a solution, such as a kind of zoom endoscope that CN201620590716, US7961401B1 are provided,
Its Zoom structure size is all bigger, is unfavorable for the miniaturization of endoscope insertion part diameter, so as to there is very big limit to applying working condition
System.Moreover, how in the case that flexible endoscope insertion tube it is curved realize reliable zoom operation, current solution is
It is not only of high cost using in endoscope head end built-in miniature motor, and be limited by the technology development of micromachine and in causing
Sight glass insertion section diameter is difficult to accomplish to minimize.
