A kind of part, and in particular to 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 generally comprises the structures such as imaging sensor, optical lens, light source illumination, pincers deferent.
Wherein, imaging sensor generallys use charge-coupled device (Charge Coupled Device, abbreviation CCD) or complementary gold
Belong to oxide semiconductor element (Complementary Metal Oxide Semiconductor, abbreviation CMOS).CCD or
CMOS is bigger, and 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, attracts
Flow is bigger.But for the leading end portion of fujinon electronic video endoscope, outer diameter is smaller, then the scope of application is more extensive, and patient's relaxes
Appropriateness 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 deferent
Internal diameter, but deferent is clamped as service aisle, the reduction of internal diameter will affect handling capacity again.
Make to clamp deferent internal diameter is as big as possible and the size of leading end portion is as small as possible, existing way is as follows: first by light
Camera lens and image sensor package are learned in a shell, is installed on leading end portion again after completing focusing school picture.The electricity of this structure
The shell of sub- endoscope, encapsulating optical camera lens and imaging sensor can occupy certain space, increase the outer diameter of leading end portion.And light
Source generallys use the method that glass light guide bundles add shell to be installed on leading end portion again, equally will increase the outer diameter of leading end portion.In addition, being
Leading end portion can be made to be connected with thinner snake bone and insertion tube, need to take over using snake bone adapter ring and pincers road, it in this way can be into one
Step increases the hard end size of insertion section.Therefore, the leading end portion size of existing fujinon electronic video endoscope is not able to satisfy wanting for patient comfort
It asks.
