Abstract

The utility model relates to a cytological sampling tool, in particular to a cytological sampler at the position of a female's uterus neck, comprising the following three parts: A sample rod, a cervix opening brush and a cervical canal brush. (1) Sample rod: Its length is 15-25cm. Sample rod perpendicularly crosses main shaft of the cervix opening brush base; (2) Cervix opening brush: It comprises a base and brush hair arranged on the base. Connecting line on the brush hair top appears in a parabola shape matched with the cervix opening; (3) cervical canal brush: It is made up of a brush rod and horizontally expanding brush hair. Top of the sample rod is connected with the bottom of the base of the cervix opening brush through a plugging or spiral structure. Lower end of the cervical canal brush is also connected with upper of the base of the cervix opening brush through a plugging or spiral structure. The structure hereabove can mainly resolve the technical problems of existing cervix brushes: Brush diameter is definite, and they cannot reach lower end of cervical canals for sampling, so that the sampling area is limited. The utility model is a composite and integral cervix cytological sampler with the sampling capacity in lower end of cervical canals, at cervix openings and in vaginal vaults.

Description

The cervical cytology sampler

Technical field:

This utility model relates to cytology's sampling instrument, cytology's sampler at particularly a kind of women's cervix uteri position.

Background technology:

Obtain the mucomembranous epithelial cell (comprising squamous epithelial cancer, glandular epithelium) of women's uterus neck, place microscopically to observe then, can help the clinician to understand the nature and extent of cervical lesions.Pathogen (virus, antibacterial, mycete), medicine (hormone) and inflammation (actute infection, chronicity is given birth to) all can cause neck tube, cervix uteri and near the epithelial specificity morphological change of vagina arched roof.Particularly when proliferative lesion takes place, for example: intraepithelial neoplasia (atypism hypertrophy, cancer in situ) and cervical cancer (adenocarcinoma, scale cancer), in the cervical cytology sample, find tumor cell early, for preventing that the state of an illness from increasing the weight of, worsening, in time take the treatment measure, the prognosis that improves patient has crucial meaning.

Pathologic finding has certain requirement to the cervical cytology sample, and sample should be evenly distributed on the slide, and structural integrity, laying are smooth, and will avoid cell accumulation agglomerating, folding and damaged, reads the sheet difficulty in order to avoid cause, and does the conclusion that makes mistake.Past, as sampling instrument, Chang Buneng obtained satisfied smear, because cell always crowds at the edge of scraping blade with wooden scraping blade, when it is coated surface of glass slide, can not accomplish firmly evenly the broken cell of normal pressure again, institute is so that in the mirror downward view, and cell is in disorder, has reduced effective field of view.

The liquid-basedcytology flaking method utilizes filter screen that impurity, blood and inflammatory cell are removed, and then by malleation and electrostatic interaction, cell is attached on the slide, becomes skim.This method has been improved greatly and has been coated with tablet quality, but clinical sampling has been proposed new requirement.The general Wallach Uterine neck bush (see figure 1) of using, it mainly is made of the base of a thief rod and a distribution bristle, fixedly connected with the base lower end in the thief rod top, with acquisition cervical mucosa epithelial cell sample, the fixed diameter of this Uterine neck bush, its central bristle is shaft-like, therefore to the sampling ability of neck tube mucosa a little less than, and can't go deep into the sampling of neck tube lower end, make the sampling point limitation to lack discrimination adenocarcinoma in peripheral scale cancer of cervix uteri and the neck tube.

The utility model content:

Main purpose of the present utility model be to provide have the neck tube lower end, cervix uteri collar extension place sampling ability, capable of being combined, incorporate cervical cytology sampler, its degree of depth of going deep into neck tube can be regulated, and can be according to the actual size and the extent of disease of cervix uteri collar extension, change the diameter of Uterine neck bush, mainly solve the fixed diameter of existing Uterine neck bush, and can't go deep into the sampling of neck tube lower end, make the technical problem of sampling point limitation.

For solving the problems of the technologies described above, this utility model is achieved in that

A kind of cervical cytology sampler is characterized in that it brushes three parts by thief rod, outer mouth brush and neck tube and form;

(1) thief rod: long 15～25cm intersects vertically with the main shaft of outer mouth brush base;

(2) outer mouth brush: form by the base and the bristle of planting on base, the connecting line of bristle tips be with the cervix uteri collar extension be complementary parabola shaped;

(3) neck tube brush: the bristle by brush holder support and horizontal development is formed;

This thief rod upper end is connected by grafting or helical structure with the base bottom of outer mouth brush, and the lower end of this neck tube brush also is connected with the base top of outer mouth brush by grafting or helical structure.

The bristle distribution of being somebody's turn to do outer mouth brush is long 0.5～2.5cm, wide 2～4cm, thick 0.5～1mm.

The bristle of this neck tube brush distributes and is turriform.

The bristle tips of this neck tube brush has a bulging, and diameter is greater than contiguous bristle.

The bristle of this neck tube brush rises twist, and keeps the pitch of 1mm～2mm.

The bristle of this outer mouth brush is planted mao form and is embarked on journey for staggered.

Make by said structure and the utlity model has following technique effect:

1, when cervical cytology is taken a sample, by select suitable outer mouth brush and neck tube brush make the profile of bristle and the inside and outside surface of cervix uteri lower end (inner surface refers to the neck tube mucosa, and outer surface refers to the covering epithelium of ectocervical) close with.During the rotation thief rod, inside and outside surface all has bristle to do vertically (or near vertical) contact with it, makes firmly to be evenly distributed, and obtains to isodensity the cytological samples of cervix uteri lower end.Use this Uterine neck bush to help to improve the satisfaction of sampling, reduce the ratio that detects of ASCUS/LSIL (ASC/low SIL).

2, when highly suspecting in the neck tube during pathological changes, can be singly with the sampling of neck tube brush.Neck tube is brushed the cytological sample that vertical bulging structure helps to take out as far as possible fully pathological changes.

The specific embodiment:

See also Fig. 2, it is the structural representation of this utility model cervical cytology sampler.It comprises three part assemblies as shown in the figure: thief rod 1, outer mouth brush 2 and neck tube brush 3.(1) thief rod 1: long 15～25cm (concrete length is adjusted as required, can be longer or shorter), and there is a polygon tenon on the top, can insert the notch of outer mouth brush bottom, form a connected structure 4 with this, be used to connect both, and the right position relation of immobile phase.Certainly, also can be the syndeton of spiral.(2) outer mouth brush 2: form by bristle 21 and base 22.Long 0.5～the 2.5cm in bristle distributed areas (adjust as required by concrete length, can be longer or shorter), wide 2～4cm (adjust as required by concrete width, can be wideer or narrower), thick 0.5～1mm (concrete thickness adjust as required, can be thicker or thinner), to be trimmed to class parabola shaped with the contact surface of cervix uteri collar extension, make it to paste clothes, to guarantee sufficient contact surface with the surface configuration of collar extension.Base is the fixture of bristle, and bristle is planted thereon, and the centre is the quarter butt that is connected with the neck tube brush, and, have overleaf for the notch that links to each other with thief rod.(3) the neck tube brush 3: be a quarter butt 31, can be twisted into by bifilar steel wire, vertically implant bristle 32 in shaft, therefore, make the bristle horizontal development, be used to stretch into sampling in the neck tube, length 1～3cm, diameter 0.3～1.5cm do not wait, and are turriform (concrete length, diameter, shape are adjusted as required, can further change), there is a bulging on the top, diameter is used for when rotating into neck tube greater than contiguous bristle, wipes the epithelial cell of mucomembranous surface, and when extracting neck tube out, take cell sample out of.The bar tail has slot, can directly be connected with outer mouth brush or thief rod, also can adopt helical structure to connect.

Shown in Fig. 3,4, this outer mouth brush and neck tube brush have the model of different size, design according to common cervix uteri form.For example: the cervix uteri constant width of chronic inflammatory disease is fat, and neck tube is lax, and bore is bigger, can add medium size neck tube brush by the outer mouth brush of large size, takes a sample; Old people's cervical atrophy, eck is narrow and small, can add small size neck tube brush by the outer mouth brush of medium size, takes a sample; Cervix uteri external form that has such as sharp Radix Crotalariae szemoensis, neck tube is elongated, can brush by small size outer mouth brush pretty plus neck tube, takes a sample.

As shown in Figure 5, the bristle of neck tube brush rises twist, and (1mm～2mm), advance so that can rotate when sampling does not omit suspicious focus, guarantees to cover the inner surface of neck tube mucosa to keep a constant pitch; Contractility is arranged simultaneously, and when running into stenosis, bristle can borrow the pitch gap crooked backward, reduces diameter to pass through the neck tube passage.

Mao form of planting of outer mouth brush is embarked on journey for staggered, so that during rotation, the zone of bristle process does not interspace, and sees Fig. 6.

During use, select suitable neck tube brush, outer mouth brush model, both are linked to each other successively with thief rod, become complete cervical cytology sampler.

Strut vaginal wall with vaginal dilator, send into the cervical cytology sampler to the cervix uteri collar extension.When neck tube brush contact with the cervix uteri collar extension, begin to rotate thief rod to same direction, until outer mouth brush with till the ectocervical mucomembranous surface contacts.

Suitably exert oneself forward, make outer mouth brush be pressed on the cervix uteri surface, and rotation thief rod 180～360 degree.Slowly withdraw from the cervical cytology sampler then, do not contact other position of vagina again in the way.

The rocking-turn in preserving liquid of cervical cytology sampler is treated that cell transfer after preserve liquid, discards for several times.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of this utility model claim change and modification, all should be technology category of the present utility model.
