Description

The present invention relates to a kind of sampling tool that is especially suitable for the sampling of cervical cytology, and combines so-called Papa tablet Coralau's test, promptly; The appearance of early stages of cancer, but this tool is also suitable for collecting cells, epithelial fragments and secretions from the cervix for other types of tests or examinations.

International Publication WO 89/10724 discloses a cervical sampling tool comprising fibers having a textured surface which stand upright attached to the surface of a brush. In one embodiment of the state-of-the-art tool, there is a textured surface on the conical end of a rod for insertion into the cervix, and two textured flexible and rearwardly inclined A protruding petal that joins the rear of the textured conical end. Sampling can be done in the cervix or outside the cervix, but taking enough cells from the outside of the cervix can be difficult because the flap tends to bend to one side when pressure is applied to the tool, while in actual sampling the operator The location of the petals is not known exactly.

According to the tool of the present invention, it comprises a rod having an axially positioned burr end at one end of the rod, a pair of resiliently flexible burr portions connected to the rear end of the axially oriented burr end at opposite sides of the rod , the burr portion constitutes a napped area with the vertically standing fibers attached thereto, as disclosed in WO 89/10724.

The object of the present invention is to produce a tool for internal and external sampling of the uterus, which tool has a textured surface, which can be placed in the correct sampling position regardless of the anatomical differences of the sampled person, and, Cells and secretions can be reliably collected from the inside and outside of the cervix and from the transition zone between them, and then the cells and secretions are spread on a glass slide to form two wide parallel bands close to each other, and then Allows sample analysis to be performed safely.

In order to achieve the above object, according to the tool of the present invention, it is characterized in that: one end of the two connecting rods is connected with each outer end of each of the above-mentioned flexible and burr parts in a hinged manner, and the other end of the above-mentioned connecting rods is The hinged connection is connected with the rod to achieve the connection between the above-mentioned flexible burr parts and the rod. The above-mentioned connecting rod and each flexible burr part are formed into a substantially regular quadrilateral structure, and the diagonals of the above-mentioned quadrilateral structure are in the above-mentioned quadrilateral Intersecting at right angles, the above-mentioned axial burr end, the above-mentioned flexible burr parts and the above-mentioned connecting rods are formed as a whole of plastic material, and the designed connecting rod has appropriate rigidity, so the tool can maintain the above-mentioned structure under normal conditions , another sliding member can move over the above-mentioned connecting rod on the above-mentioned rod.

Referring to the accompanying drawings, an embodiment of the present invention is described in more detail, wherein:

Figure 1 is a perspective view of a tool according to the invention;

Figure 2 is a perspective view of the opposite side of the tool shown in Figure 1;

Figure 3 shows a perspective view of the tool shown in Figure 1 when a sample taken with the tool is spread on a glass slide.

The tool for sampling the interior of the uterus and the exterior of the cervix comprises an injection molded stem 10 of thermoplastic. In order to obtain the required strength and elasticity, the structure of the rod is a cross-section rod with a shank 11 at one end, a breaking notch 12 near the other end, and a sampling burr integrated with the rod 10 at the last-mentioned end. Above-mentioned brush comprises a slightly conical end portion 13, and the rear end portion of end portion 13 has two petal-shaped parts 14, and each face opposite with end 13 is connected, and petal-shaped part 14 has elasticity and flexibility, and the end part 13 and part 14 are all processed through napping, so the above-mentioned two parts form a continuous burr surface 15, a pair of connecting rods 16 are made integral with part 14 and rod 10, and these connecting rods and part 14 jointly form a regular A quadrilateral of , in this case a rhombus or an approximate square, whose diagonals actually meet at right angles in the quadrilateral. Between the link 16 and the part 14 is the hinge 17, and the hinge 18 between the link and the bar 10, most preferably they comprise thinner sections of plastic material, and have a suitable rigidity to make the tool in the normal state. While maintaining its structure, as shown in provocations 1 and 2, part 14 is curved with a concave shape on the outside of the burr.

Hinge edges 17 and 18 are suitably rigid so that the substantially right-angled orthogonal sections can be tilted laterally at end 13, while said orthogonal sections are suitably rigid so that end 13 can be tilted when the orthogonal sections are in an inclined position. Inserts into the cervix without difficulty. A spacer 19 of U-section is integral with the bottom of the end 13 located between the parts 14, the spacer being flared towards its free end. At the junction of the two links 16 there is a cavity 20 capable of accommodating the free end of the spacer 19 mentioned above. A slider 21 is movable along the rod 10, which slider can be pushed over the link 16 to bring the two links closer together, as shown in FIG. 3 .

When the described instrument is used for sampling, its end 13 is inserted into the cervix, the part 14 facing the outside of the cervix, when pressure is applied on the rod 10, the pressure is transmitted to the outer part of the part 14 through the connecting rod 16 to force The part 14 is close to the outside of the cervix, the spacer 19 engages a connecting rod 16 and may be accommodated by the cavity 20, in which case the spacer engages the rod 10, thus stabilizing the end 13.

When the tool has been sampled by rotation and withdrawn from the patient, and the collected sample has been applied to the glass slide, then the slider 21 is moved over the link 16 so that the continuous burr surface 15 between the end 13 and the hinge 17 is almost become a straight line as shown in Figure 3.

One side of the end 13 and part of the part 14 were applied to the glass slide first, and then the other side and the other part of the part 14 were continued. According to this smearing method: a part of the end 13 and part 14 is in the main plane position of the horizontal state and faces the glass slide, so two ribbon samples are obtained when smearing on the glass slide, and each of the above two ribbons It is easy to identify the transition zone in the extent representing the inner cervix and the outer cervix. Sample analysis on glass slides is convenient and facilitates reliable diagnosis.

The end of the tool, that is, the part containing the sample obtained on the burr part 15, can be broken off at the breaking notch 12 and incorporated into a test tube, sending the obtained sample out or transferring the sample from the brush in the liquid of the test tube. Wash up and down for sample processing instead of smearing on glass slides.

Certainly, the above-mentioned embodiment can be modified. The quadrilateral formed by the part 14 and the connecting rod 17 is not necessarily a rhombus or a square. As shown in the figure, the connecting rod 16 may be longer than the part 14.

Typically, the fibers making up the glitches 15 are at least about 0.5 mm in length, preferably from 0.5-3 mm in diameter, have a diameter of about several 0.01 mm, and have only a minimal possibility of causing bleeding when sampled. The tool is injection molded from thermoplastic, a suitable plastic is polypropylene, but other plastics are suggested for use with the tool in accordance with the invention.
