Description

Sampling tool

The present invention relates to a kind of sampling instrument and be specially adapted to the sampling that cervical cell is learned, and draw the Ubbelohde test, promptly in conjunction with so-called handkerchief handkerchief sheet section; Early stage cervical cancer cell specimen smear check, this test are used to offer an explanation the appearance of the initial stage of cervical cancer or cancer, but this instrument also is applicable to from cervix uteri and gathers cell, epithelium fragment and secretions, are used for other all kinds of tests or inspection.

Disclose a kind of cervix uteri sampling instrument among the international publication WO89/10724, above-mentioned instrument includes the fiber through the napping treatment surface, and this fiber is the axial surface that is attached to brush vertically.In an embodiment of the instrument of prior art level, on taper shape one end of a bar, have through surface that napping is handled in order to insert cervix uteri, and having two to handle the flexible and outstanding lobe that recedes on its surface through napping, this lobe is connected with rear portion through the conical end of napping processing.Sampling can be carried out in cervix uteri people portion or cervix uteri outside, but taking enough cells from the cervix uteri outside may be difficult, because when when instrument is exerted pressure, above-mentioned lobe is easily to a lateral bending song, simultaneously can not know for sure the position of lobe of operator in actual samples.

It comprises a bar according to instrument of the present invention, the burr end that has axial location at an end of bar, there is the burr part of a pair of elastic force flexibility to be connected with the rear end of axial location burr end at relative each face place of bar, the burr part constitutes the zone of handling through napping with the vertical axial fiber that is attached to this place, as disclosed content in data WO89/10724.

The objective of the invention is to produce a kind of instrument that is used for inside, uterus and outer samples, this instrument has the surface of handling through napping, no matter sampled person has anatomy difference, this instrument all can place correct sample position, and, can all can reliably gather cell and secretions from cervix uteri transition zones inner and outside and between them, spread upon on the glass slide with being about to cell and secretions, form two approaching wide parallel ribbons mutually, allow to carry out safely sample analysis then.

In order to achieve the above object, according to instrument of the present invention, it is characterized in that: the end by two connecting rods is connected with articulated manner each outer end with above-mentioned each flexible burr burr part, and the other end of above-mentioned each connecting rod is connected with bar in hinged way to reach above-mentioned each flexible burr part and is connected with bar, above-mentioned connecting rod and each flexible burr partly form one and come down to well-regulated quadrilateral structure, the diagonal of above-mentioned quadrilateral structure in above-mentioned tetragon mutually with right angle intersection, above-mentioned axial burr end, above-mentioned each flexible burr part and above-mentioned each connecting rod form the integral body of a plastic material, the connecting rod of design has appropriate rigidity, therefore this instrument can keep said structure in normal condition, and it is mobile on above-mentioned bar that other has a sliding part can cross above-mentioned connecting rod.

With reference to accompanying drawing, an embodiment of the present invention is narrated in more detail, wherein:

Fig. 1 is according to the perspective view of instrument of the present invention;

Fig. 2 is at the perspective view of the opposite one side of this instrument shown in Fig. 1;

Shown in Figure 3 when the sample of obtaining with this instrument spreads upon glass slide, the perspective view of instrument shown in Figure 1.

The instrument that is used for inside, uterus and cervix uteri outer samples comprises the injection-molded bar 10 of a thermoplastic.For the intensity and the elasticity that obtain to need, the structure of bar is that an end of star section bar has a shank 11, and near the other end breach 12 that fractures, this end of in the end mentioning has sampling burr and bar 10 to become one.Above-mentioned brush comprises a slightly conical end 13, the rearward end of end 13 has two lobe shape parts 14, each face relative with end 13 connects, lobe shape part 14 has elasticity and flexible, end 13 and part 14 are all handled through napping, therefore above-mentioned two parts form successive burr surface 15, pair of links 16 is made integral body with part 14 and bar 10, and these connecting rods and the well-regulated tetragon of the common in fact formation of part 14, be rhombus or approximate square in this example, in fact their diagonal meets at right angle in tetragon.Between connecting rod 16 and part 14, be hinge 17, and the hinge 18 between connecting rod and bar 10, the most preferably they include the thinner part of plastic material, and have suitable rigidity and make instrument when normal condition, keep its structure, as quarrel shown in 1 and 2, part 14 is wandered and is with arc to have spill in the outside of burr.

Hinge limit 17 and 18 has suitable rigidity, makes the in fact rectangular quadrature component can the 13 places lateral tilt in the end, has suitably inflexible above-mentioned quadrature component simultaneously and end 13 can not had insert cervix uteri when quadrature component is in obliquity difficultly.The separator 19 in one U-shaped cross section and be an integral body in the bottom of the end between part 14 13, separator opens to its free end.At the two binding site places that connect part 16 one cavity 20 is arranged, this cavity can hold the free end of above-mentioned separator 19.One sliding part 21 can move along bar 10, and this sliding part can be pushed crosses the close relatively to reach two connecting rods of connecting rod 16, as shown in Figure 3.

When the instrument of being narrated is used to take a sample, cervix uteri is inserted in its end 13, part 14 is facing to the cervix uteri outside, and when exerting pressure at bar 10, then pressure passes to the Outboard Sections of part 14 by connecting rod 16, to force part 14 near the cervix uteri outside, separator 19 engages a connecting rod 16, and may be held by cavity 20, in the case, separator engages with bar 10, therefore makes end 13 stable.

When instrument rotating sampling and to withdraw from from the patient, and the sample of gathering is spread upon on the glass slide, mobile then sliding part 21 is crossed connecting rod 16 makes the continuous burr surface 15 between end 13 and hinge 17 almost become straight line as shown in Figure 3.

One side of end 13 and the part of part 14 are smeared sample earlier on glass slide, and another part of opposite side and part 14 is proceeded again then.According to this smearing method: the part of end 13 and part 14 is in the principal plane position subtend glass slide of level, thereby obtained two bands samples when on glass slide, smearing, in representing the scope of cervix uteri inside and cervix uteri outside respectively, above-mentioned two bands are easy to determine its transition zone.Sample analysis on glass slide is very convenient, helps reliable diagnosis.

The end of this instrument, that is: include that part that on burr part 15, obtains sample, can fracture, incorporate into into test tube at breach 12 places that fracture, the sample of obtaining is sent or in the liquid of test tube, sample is washed from brush, spread upon on the glass slide with replacement for handling sample.

Certainly, above-mentioned embodiment can be revised, part 14 and connecting rod 17 formed tetragons be not daily necessities be rhombus or square, as shown in FIG., connecting rod 16 may be longer than part 14.

Under typical situation, the fibre length that constitutes burr 15 is at least about 0.5 millimeter, and the best is from the 0.5-3 millimeter, and its diameter is about several 0.01 millimeter, only causes the minimum probability of bleeding when sampling.This instrument is that the thermoplastic process is injection-molded, and suitable plastics are polypropylene, but also can advise being applied to this instrument according to other plastics of the present invention.
