Description
Technical field
The present invention relates to gynecological diagnosis instrument field, specifically a kind of cervical sampling device.
Background technique
Body in the reason of pathology are research human body diseases generations, mechanism, the rule of development and lysis
The preclinical medicine science that morphosis, functional metabolism variation and lesion lapse to.Cell pathology cell pathology
It (cytopathology) is mainly the reason of study of disease occurs, nosogenesis and disease according to intracellular unusual condition
In generating process, the rule that the physiological function of cell changes is to pass through inspection to propose the foundation of diagnosis and disease preventing and treating
The Morphological Features of cell are looked into, health and disorder in screening, an important means of diagnosis, research are carried out.Clinically, cell pathology
It learns to examine and be widely used in the diagnosis and screening of cervical lesions.Uterine neck screening is that TCT is ThinPrep cytologic test
Abbreviation, also known as cancer screening, uterine neck give protection against cancer cytolgical examination.TCT cancer screening is using Thinprep pap test
Detection system detection cervical cell simultaneously carries out TBS cytology specification diagnosis, it is a kind of current cervical carcinoma state-of-the-art in the world
Cytolgical examination technology, satisfaction and the uterine neck that sample is significantly improved compared with traditional cervical smear Pap smear inspection are different
Normal cell recall rate.TCT cancer screening is 100% to the recall rate of cervical cancer cell, while can also find precancerous lesion,
Microorganism infection such as mould, trichomonad, Chlamydia etc..Its inspection method belongs to woundless testing, only need to be sloughed side by inspection women
Trouser legs are lain down in examination couch, take sterile vaginal dilator that vagina and uterine neck are completely exposed by health care professional, sterilize vagina
And after uterine neck, with dedicated soft swipe cervix opening secretion, it is placed in be detected in special culture solution.It is within general testing result 1 to 3 day
It can obtain.With popularizing for gynaecology's health idea, uterine neck screening is more and more appeared in routine physical examination project.However
In general clinic, inspection body, the operation level of medical staff has obvious gap compared to large hospital, is exaggerated palace significantly
The influence degree of difficult point in neck sampling operation to inspection result.
The existing Major medical instrument for clinically carrying out uterine neck screening is Uterine neck bush.The existing soft brush of sampling is typically all mountain
The brush head of row (herringbone), the swipe cell sample under cervix opening rotation number.Female sex organ have vagina is long, secretion compared with
The features such as more, although needing to strut vagina using duckbilled device before sampling, the two sides of duckbilled device still expose big face
Long-pending inner wall, simultaneously as light condition is bad, doctor is easy to scrape when being sent into sampling brush to arrive vaginal wall, and operation difficulty is big,
The impurity of contamination obscures taken cell sample, influences inspection result.Especially in community clinic, physical examination mechanism, because putting
" rebuffed " problem when entering soft brush and caused by inspection result it is inaccurate, even more seem especially prominent.
Summary of the invention
The purpose of the present invention is to provide a kind of cervical sampling device, its effectively convenient constraint sampling brush is put into row
Journey improves the accuracy that this is sampled when sampling, improves sampling level and efficiency.
The present invention to achieve the above object, is achieved through the following technical solutions：
A kind of cervical sampling device, including the duckbilled device being used in combination and sampling brush,
The duckbilled device includes upper page and nextpage, and the inboard surface of the upper page is placed in the middle along its length to be equipped with upper rail
Road slot, the inboard surface of the nextpage is placed in the middle along its length to be equipped with lower railway slot,
The sampling brush includes mounting rod, inner shaft, brush head, lacing wire, and the midline of the mounting rod is set along its length
There is axis hole, the inner shaft is through axis hole and can slide axially along axis hole, and the brush head is fixed on the front end of inner shaft, the installation
The top and bottom of bar have been respectively articulated with the first strut and the second strut, and first strut and the second strut are far from hinged place
One end is equipped with idler wheel, first strut and the V-shaped structure of the second strut of same side, and described the first of same side
Strut and the second strut are both secured in a lacing wire, and the lacing wire is elastic string body and its both ends is separately fixed at mounting rod
On.
The mounting rod includes symmetrically overlapping upper body of rod and lower body of rod, the bottom surface of the upper body of rod and the top of lower body of rod
Face is fixedly connected, and the corresponding section that is equipped in the top surface of the bottom surface of the upper body of rod and lower body of rod is semicircular through slot, and two
The through slot closes up to form axis hole.
The brush head is chevron brush head.
It is respectively equipped with through-hole on first strut and the second strut, is equipped with connecting rod, the lacing wire packet in the through-hole
Elastic string and fake are included, the fake is symmetrically fixed in elastic string, and the fake is fixed in connecting rod, and the lacing wire makes
First strut and the second strut form V-type scissors articulated structure, and the vertical range between upper and lower idler wheel is made to be greater than upper rail slot
With the vertical range between lower railway slot.
The interior the tip of the axis is equipped with handle.
The prior art is compared, the beneficial effects of the present invention are：
First strut and the second strut respectively form a scissors in the mounting rod top surface and bottom surface by the pulling of lacing wire
V-arrangement articulated structure, the vertical range between upper bottom roller is greater than the distance between page and nextpage front on duckbilled device, makes first
The V-type linkwork that strut and the second strut are formed, which can be tensioned, to be supported between upper rail slot and lower railway slot, and operator will
After sampling brush alignment upper rail slot and lower railway slot push-in, inwardly touch can just make sampling brush placed in the middle by duckbilled device.Row
Route line is maintained at the immediate vicinity of duckbilled device, and brush head is avoided to touch vaginal walls, guarantees the accuracy of sample acquired by brush head.
The difficulty requirement of operator significantly, improves sampling level and efficiency.
The advantage of the present apparatus also resides in, when the position for needing to adjust brush head, can directly press lift mounting rod angle, first
The limit for the V-type linkwork cooperation lacing wire that strut and the second strut are formed has considerable flexibility and adaptability, facilitates tune
It is whole.
