Abstract
A uterine cervix sampler for sampling from the mucosa on the surface of uterine cervix is composed of brush head, brush handle and connecting mechanism between brush head and brush handle. Said brush head has E-letter shape consisting of two L shapes, on which there is a sampling material.
Description
Technical field
The present invention relates to a kind of uterine neck tissue drawer that is used for gathering when gynecological cytology is checked the sample on cervical mucosa surface.
Background technology
The early lesion of cervical cancer with the naked eye is difficult for identification, in the time with the naked eye can recognizing, has often developed into the middle and advanced stage cancer.The early stage cervical lesions of the method inspection of cervical cytology is effective, and the mortality rate that cervical cancer is caused greatly reduces.The first step is collection of specimens in the clinical cervical cell checking process.The most primary method is to wipe away the sample of getting the cervical mucosa surface with a cotton swab, is applied to carry out the microscopic examination analysis on the microscope slide behind pap staining, or does other laboratory detection.When drawing materials with cotton swab, sticking cell thereon is difficult for separating fully, misses observed cell easily, cause false negative, and because the cotton fiber water absorption is strong, the dry easily distortion of cell, influence the morphological observation of cell, bring difficulty, go out of use now to diagnosis.The normal at present collection of specimens instrument that adopts is cervix uteri scraper plate, cytology brush, Uterine neck bush etc.
These sampling instruments respectively have its pluses and minuses: the spade curette that the cervix uteri scraper plate is wooden or plastics are made, material is hard, the easy damaged cervix uteri also causes bleeding, because fixed in shape is stiff, and the cervix uteri surface is complexity of curved surface, shape, be difficult for the specimen on cervix uteri surface is all collected, particularly the cell at cervical clefts position.
Cytology brush (U.S.Pat.No.4759376.) is hard straight bar-shaped, and simple shape is comparatively desirable for the collection of specimens effect at cervical canal position, but for ectocervical collection of specimens difficulty comparatively.
The bristle of the Uterine neck bush that uses is longer at present, and forms " mountain " shape owing to bristle length is different, and placing the cervix uteri mouth to rotate for several times can be than comprehensive engagement cervix uteri collar extension.But its comprehensive engagement is because the length of bristle forms, therefore the dynamics on the hair contact cervix uteri surface of the different parts of brush is just even inadequately, simultaneously, because bristle is soft, becoming mildewed of middle part is difficult for inserting cervical canal, even insert, because cervical canal is very thick flesh sex organization, stronger anti-flexible strength is arranged, and bristle also is difficult at the cervical canal internal rotation by the torsion of itself; And, because all being same directions, arranges bristle, all perpendicular to the cross section of cervix uteri, the angle near bristle of temporary abode for an emperor on progresses neck tube and cervical mucosa surface is more little so more, (insert the bristle of cervical canal) during to cervical canal, with the vanishing of mucomembranous surface angle, so, the bristle brushing campaign on the cervical mucosa surface just becoming bristle is cervical mucosa surface dragging along the bristle machine direction, the strength that bristle imposes on the cervical mucosa surface greatly weakens, the collection effect of specimen greatly reduces, particularly outer 1/3 this zone to the cervix uteri collar extension of cervical canal includes the part of cervix uteri mouth squamous epithelial cancer and columnar epithelium handing-over, it is the zone occurred frequently of pathological changes, therefore the effect of drawing materials of this Uterine neck bush is superior unlike other utensils, and often two or more instrument combines result (" Comprehensive Cancer Cytopathology of the Cervix Uteri " the .Yi-Jing Shu that just can obtain than satisfied; Etienne Gloor.Published by McGraw-Hill Book Company, New York.1995; P 15-17.).But will operate loaded down with trivial detailsly like this, lose time, for operating technology personnel's training requirement height, the utensil of waste is many, increases medical treatment cost and expense.More be not suitable for " liquid base cytology detection system ", to the draw materials head of instrument of the general requirement of this system drops at once and leaves in the bottle that cell-preservation liquid is housed of special use, it is more and more that this system uses at present, and the trend that replaces traditional Pap smear method is arranged.Also there are some patent designs to attempt above-mentioned shortcoming is improved.U.S.Pat.No.5370128 has kept bristle to be the shape of " mountain word ", just intermediary bristle is replaced with the head of cytology brush, so greatly strengthened the effect of drawing materials at cervical canal position, but the bristle of cytology brush is vertical mutually with the bristle direction of Uterine neck bush, all be not orthogonal to mucomembranous surface, its position that joins mutually is vertical angle, can not match with the curved surface of cervix uteri, form the inanition of the application of force, cause the bristle of Uterine neck bush of this design and the loose contact on cervical mucosa surface, and this position of the Uterine neck bush of this design when drawing materials just in time corresponding to the pathological changes zone occurred frequently of cervix uteri mouth squamous epithelial cancer and columnar epithelium handing-over.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of uterine neck tissue drawer, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: brush, brush holder and the bindiny mechanism that brush is connected with brush holder; Described brush is by two opposing " mountain " font or " L " types of forming of " L " type; The knee of described " L " type is an arcwall face, comprises that in the inner surface place of " L " type one side is fixed with it, another side is can be from the object of cervical mucosa sampling.
Compared with prior art, the invention has the beneficial effects as follows: because brush finish and cervical mucosa surface fit like a glove, can finish the operation of drawing materials as long as the middle part of uterine neck tissue drawer inserted cervical canal and impose suitable pressure rotation brush holder, be convenient to standardization, standardized operation, technical staff to operation is easy to training, in once-through operation, obtain collar extension and the more specimen of cervical canal mucomembranous surface in the cervix uteri all-sidedly and accurately fast simultaneously, improved work efficiency.
