Description
Technical field
The present invention relates to a kind of medical endoscopes, and in particular to a kind of leading end portion of fujinon electronic video endoscope.
Background technology
Endoscope be it is a kind of be widely used general medical instrument, be directly inserted into human body carry 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 coupling device (Charge Coup led Device, abbreviation CCD) or complementary metal oxygen
Compound semiconductor devices (Comp lementary 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 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 sizes are certain, to reduce the outer diameter of leading end portion, only reduce pincers road bore, but service aisle
Reduction can influence 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
The problem of size is as small as possible.
Current common practices is as follows：First by optical lens and image sensor package in a shell, focusing is completed
Leading end portion is installed on again after the picture of school.This way, shell can occupy certain space, increase the outer diameter of leading end portion, and produce
It is extremely inefficient.In addition, lighting source generally use glass light guide bundles is installed on leading end portion, this can cause two problems：Firstth, scheme
As needing separately to add light-source system on processor, second, light guide bundles can occupy expensive real estate in insertion tube and bending section, be unfavorable for
Clamp the maximization of deferent.And clamp deferent and be mounted in parallel with imaging sensor in leading end portion, the size for being unfavorable for leading end portion minimizes.
What is more important, current endoscope industry production technique is cumbersome, and production efficiency is extremely low, and existing technology cannot
Meet the production demand of disposable endoscope.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of leading end portion of fujinon electronic video endoscope, it can be realized in pincers road
Footpath maximizes and leading end portion size minimizes.
In order to solve the above technical problems, the technical solution of the leading end portion of fujinon electronic video endoscope of the present invention is：
Including first end cap 7 and apex pedestal 8, the top of the bottom connection apex pedestal 8 of first end cap 7；Elder generation's end cap 7 is simultaneously
Through hole there are two opening up is arranged, shell 3, biopsy channel hole 9 of second through hole as first end cap are fixedly installed in first through hole 11；Shell
Optical lens 1 and imaging sensor 2 are fixedly installed in 3；Imaging sensor 2 is located at the lower section of optical lens 1；Optical lens 1
Imaging system is formed with imaging sensor 2；The both sides of shell 3 are fixedly installed LED4 respectively；The apex pedestal 8 offers two
A passage, first passage 14 pass through hole as the FPC's 6 of imaging system module；Second channel is clamped by the front end to communicate with each other
Road hole 15 and rear end biopsy channel hole 18 form, and are formed between the central axis of front end biopsy channel hole 15 and the central axis of apex pedestal 8
One angle, to realize that the inclination of front end biopsy channel hole 15 is arranged；The centerline axis parallel of rear end biopsy channel hole 18 is in the center of biopsy channel hole 9
Axis, for mounting clamp deferent 19；It aligns with the biopsy channel hole 9 of first end cap 7 front end of front end biopsy channel hole 15.
The leading end portion of fujinon electronic video endoscope of the present invention has technical effect that：
The imaging system that the present invention is formed optical lens and imaging sensor is encapsulated in the outer of high dimensional accuracy in advance
In shell, can clearly it be imaged after encapsulation, it is no longer necessary to school picture of focusing again, so as to improve production efficiency.
Leading end portion is divided into two parts of first end cap and apex pedestal by the present invention, can easily and reliably pacify imaging system
It is installed in leading end portion, and convenient for the high-volume of imaging system, so as to meet large batch of production requirement.
The imaging system of the present invention realizes illumination using LED, does not use traditional glass light guide bundles illumination, can be pincers
Road hole saves larger space, while imaging sensor saves lighting system.
The present invention exists only in the rear end of apex pedestal for the rear end biopsy channel hole of mounting clamp deferent, can make pincers deferent only
It mounted on the later half end of apex pedestal, arranges so as to misplace with imaging system, avoids influence of the front end imaging system to pincers deferent,
Front end then using apex pedestal and first end cap 7 self-assembling formation pincers road, can maximize biopsy channel hole.
The present invention realizes that biopsy channel hole with clamping being interconnected for deferent, makes pincers using the tilted front end biopsy channel hole of apex pedestal
The central axis of road hole and pincers deferent on the same axis, can either not ensure the diameter of larger pincers deferent and attraction flow,
The rear end size of apex pedestal can be reduced again, be conducive to reduce bending section diameter, so as to reduce insertion section diameter.
The present invention makes front end biopsy channel hole tilt arrangement, avoids the influence of the PCB and shell of imaging system module just, can
Ensureing the maximization of biopsy channel hole can reduce again rear end size, so as to ensure that curved part of endoscope and leading end portion size minimize.
Further, the connecting pin of the first end cap 7 is formed with cylindrical boss 12 and semicircle boss 13；The apex
The connecting pin of pedestal 8 offers boss connecting hole 16 and semicircular indentations 17, the cylinder of boss connecting hole 16 and first end cap 7
Boss 12 is engaged, and semicircular indentations 17 are engaged with the semicircle boss 13 of first end cap 7；Pass through the circular cylindrical projection of first end cap 7
The semicircle boss 13 and first end group of mating connection and first end cap 7 between platform 12 and the boss connecting hole 16 of apex pedestal 8
Being fixedly connected between first end cap 7 and apex pedestal 8 is realized in mating connection between the semicircular indentations 17 of seat 8.
Further, the shell 3 and two groups of LED4 are packaged on PCB5 jointly, become an imaging system module；Often
Group LED4 includes an at least high brightness adopting surface mounted LED.LED4 described in two groups is symmetrical arranged compared with shell 3.The present invention uses
Symmetrically arranged two groups of LED replace conventional pilot beam lighting, then shell and LED are packaged on PCB, can realize that modularization is grasped
Make, convenient for high-volume automated production.
Further, semi-circular indentation 10 there are two being opened up on the PCB5, the semicircle of semicircular indentations 17 and first end cap 7
Shape boss 13 is engaged, in order to the assembling of first end cap 7 and apex pedestal 8；Rectangular notch 20 is further opened on PCB 5, for pincers
Road hole 9 reserves space.
Further, the connecting line of described image sensor 2 and LED4 are directly drawn with FPC 6.The image of the present invention passes
The connecting line of sensor and LED are directly drawn with FPC, can be saved human weld's step, be further improved production efficiency, are suitble to need
The disposable endoscope to be produced in enormous quantities.
Further, the first end cap 7 uses transparent material；And the shell 3 uses light-proof material, to ensure to be imaged
System obtains clearly image.
