Description
Technical field
The utility model relates to a kind of medical endoscopes, and in particular to a kind of leading end portion of fujinon electronic video endoscope.
Background technique
Endoscope is a kind of very widely used medical instrument, is directly inserted into human body and carries out observation and diagnosis and treatment disease
Disease.As the component for initially entering human body, performance and the patient of endoscope are directly affected positioned at the leading end portion of its front end
Comfort.
The leading end portion of fujinon electronic video endoscope includes the structures such as imaging sensor, optical lens, lighting source, pincers deferent.Wherein
Imaging sensor generally uses charge-coupled device (Charge Coupled Device, abbreviation CCD) or complementary metal to aoxidize
Object semiconductor devices (Complementary Metal Oxide Semiconductor, abbreviation CMOS).CCD or CMOS are got over
Greatly, imaging effect is more clear；And the internal diameter for clamping deferent is bigger, handling capacity is stronger, and the instrument of support is more, and flow is attracted to get over
Greatly.
But for leading end portion, outer diameter is smaller, then the scope of application is more extensive, and the comfort level of patient is better.Therefore
In the case where CCD or CMOS size is certain, to reduce the outer diameter of leading end portion, only reduce pincers road bore, but service aisle
Reduction will affect handling capacity again.Therefore it is clear to need to solve imaging effect, and clamps that road bore is as big as possible and leading end portion
Size problem as small as possible.
Current common practices is as follows: first by optical lens and image sensor package in a shell, completing focusing
It is installed on leading end portion again after the picture of school.This way, shell can occupy certain space, increase the outer diameter of leading end portion, and produce
Efficiency is extremely low.In addition, lighting source, which generallys use glass light guide bundles, is installed on leading end portion, this can cause two problems: the first, scheming
As needing separately to add light-source system on processor, second, light guide bundles can occupy the expensive real estate in insertion tube and bending section, be unfavorable for
Clamp the maximization of deferent.And it clamps deferent and is mounted in parallel the size minimum for being unfavorable for leading end portion in leading end portion with imaging sensor.
