Description

Disposable Cell Curette

The present invention relates to a cell harvester which can be inserted into the cervix and can safely and sufficiently collect cells of the cervix through inhalation.

Recently, cervical cancer has been decreasing with the generalization of cervical cytology.

On the other hand, as a method of performing cervical cytology (Pap smears) in the obstetrician has also been developed, the cells are usually referred to as glass slides, but in order to improve the accuracy of the cytopathology, the cells collected from the cervix are removed And the inspection method for transporting it is becoming common.

As shown in FIG. 1, conventionally, cell collectors 10 and 20 having support portions 11 and 21, handle portions 13 and 23, and cell collecting portions 15 and 25, 2, the support part 11 is inserted into the cervix through the vagina, the cell-harvesting part 15 is brought into close contact with the cervix 10, and the cells are collected by rotating or rotating the cervix 10 .

However, the conventional cell harvester has a problem that the cell-harvesting part 15 comes into contact with other parts of the body other than the cervix during the process of inserting or drawing the cervix.

In this case, since the cross section of the cell harvesting part 15 is sharp, other parts of the body to be contacted are damaged, and the collected cells are contaminated and the accurate inspection can not be performed.

In addition, since the conventional cell harvester has a limitation in the size and area of the cell harvesting part 15, it is difficult to collect a sufficient amount of cells necessary for the inspection at a time, and thus it is inconvenient to repeat the above procedure several times.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

FIG. 3 is an exploded perspective view of a cell harvester according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view of a cell harvester according to an embodiment of the present invention.

3 and 4, the cell harvester according to an embodiment of the present invention includes an insertion tube 110 and a rod member 120 inserted into the insertion tube 110. As shown in FIG.

The insertion tube 110 is a hollow tube having both a front end and a rear end opposite to the front end, and is easily inserted into the uterus through the vagina of a woman. The insertion tube 110 may be made of a flexible material so as to be sealed with the rod member 120.

In addition, the insertion tube 110 should be manufactured in such a manner that a sufficient length of the insertion tube 110 is secured beyond the distance from the vagina to the cervix, taking into account that the operator must perform the insertion procedure by holding the insertion tube 110 by hand with the outside of the vagina , It is preferable to have a circular cross-section and have a small outer diameter so as to minimize a foreign body feeling without damaging the body during insertion. In this embodiment, the insertion tube 110 is manufactured to have a length of 20 cm and a diameter of 8 mm.

On the other hand, a scale 111 is preferably displayed on the surface of the insertion tube 110 so that a practitioner can easily grasp the insertion tube 110 inserted into the body with the naked eye.

The rod member 120 is made longer than the insertion tube 110, and the front end of the rod member 120 is inserted and assembled into the rear end of the insertion tube 110. The rod member 120 is assembled to the insertion tube 110 such that the front end of the rod member 120 is positioned in the insertion tube 110 and the rear end of the rod member 120 protrudes from the rear end of the insertion tube 110. In this state, Is inserted into the cervix.

At least one or more cell-cutting grooves 121 are formed on the surface of the front end of the rod member 120. The cell-cutting trench 121 has a sharp edge to serve as a blade. The cell cutting trench 121 is located inside the insertion tube 110 when the rod member 120 is assembled to the insertion tube 110.

In addition, a cell harvesting unit 122 is provided at the front end of the rod member 120. The cell harvesting unit 122 may be formed in various shapes such as a knife or a brush so as to cut or collect cervical cells. In the present embodiment, the cell harvesting unit 122 is formed as a blade having a plurality of circumferentially formed blades at regular intervals around the axis of the rod member.

The cell harvesting part 122 is located inside the insertion tube 110 in a state where the rod member 120 is assembled to the insertion tube 110.

A handle 123 is provided at the rear end of the rod member 120 protruded from the rear end of the insertion tube 110 so as to facilitate forward or backward movement or rotation of the rod member 120 in the insertion tube 110 Respectively. Therefore, when the practitioner grips the handle 123 and moves the rod member 120 forward, the front end of the rod member 120 including the cell harvesting unit 122 is positioned inside the insertion tube 110, And is drawn out to the outside through the front opening of the tube 110.

The handle 123 is formed to have a larger diameter than the diameter of the insertion tube 110 so as to engage with the rear end of the insertion tube 110. The rear end of the rod member 120 is completely inserted into the insertion tube 110 or the rod member 120 is drawn excessively from the opening front end of the insertion tube 110 by the pulling part 123, Damage incidents are prevented.

According to the present invention, the rod member 120 is configured to apply a suction force to the front end of the insertion tube 110 while reducing the internal pressure of the insertion tube 110 when the rod member 120 is moved backward. The outer diameter of the rod member 120 is made to approach the inner diameter of the insertion tube 110 so that the rod member 120 is in intimate contact with the insertion tube 110.

Although not shown in the drawing, the rod member 120 may be provided with an insertion tube 110, which is inserted into the rod member 120 so as to apply a suction force to the front end of the insertion tube 110 while reducing the internal pressure of the insertion tube 110, It is also possible to apply a sealing ring in airtight contact with the inner surface of the base 110.

The process of collecting cells using the cell harvester of the present invention thus constructed is as follows.

5 is a view showing a state in which a cell harvester is inserted into the cervix 10 as a state diagram of use according to an embodiment of the present invention.

As shown in FIG. 5, first, the insertion tube 110 with the rod member 120 assembled is inserted into the cervix 10 through the vagina. At this time, since the diameter of the insertion tube 110 is only 8 mm, the operator can perform the insertion operation very easily, and the patient can receive the insertion operation safely and comfortably without any foreign sensation or rejection feeling due to the insertion.

Since the cell harvesting unit 122 and the rod member 120 are completely inserted into the insertion tube 110 and the insertion is performed to the cervix 10, the cell harvesting unit 122 and the cell- The contact portion 121 is intrinsically blocked from contact with the body during the insertion process. Therefore, damage to the body part located on the insertion path does not occur.

On the other hand, the practitioner can easily grasp the insertion depth of the insertion tube 110 through the scale 111 displayed on the insertion tube 110. Therefore, the same operator can easily grasp the degree of insertion in the subsequent procedure.

6 is a view showing a state of use according to an embodiment of the present invention in which the rod member 120 is pulled out from the insertion tube 110 and the cells C of the cervix 10 are cut, FIG. 10 is a view showing a state in which the cut member is sucked into the insertion tube 110 as the rod member 120 is retracted into the insertion tube 110 as a state of use according to an embodiment of the present invention.

6, when the insertion tube 110 reaches the cervix 10 and is brought into close contact with the cervix 10, when the insertion tube 110 is held by the grip 123 of the rod member 120, . When the rod member 120 moves forward, the front end of the cell harvesting unit 122 and the rod member 120 provided at the front end of the rod member 120 are pulled out from the insertion tube 110. In this state, The cells C of the cervix 10 are cleaved while the cell harvesting portion 122 and the cell dividing grooves 121 come into contact with the cervix 10 .

Therefore, since the cell C is cut through the operation of rotating the rod member 120 through the cell cutting groove 121 formed on the front end surface of the rod member 120, The cells (C) can be collected.

At this time, since the diameter of the handle 123 is larger than the diameter of the insertion tube 110, the rear end of the rod member 120 is not completely inserted into the insertion tube 110. If the rod member 120 is completely inserted into the insertion tube 110 to the rear end of the rod member, the rod member 120 can not be moved forward and backward and can not be rotated. In addition, since the diameter of the grip portion 123 is larger than the diameter of the insertion tube 110, the length of the rod member 120 drawn out from the open front end of the insertion tube 110 is limited. Accordingly, the rod member 120 is drawn too far from the open front end of the insertion tube 110, so that there is no accident that the body part is damaged.

Next, when a sufficient amount of the cells C necessary for the inspection is cut, the handle member 123 of the rod member 120 is pulled backward as shown in Fig. 7 to move the rod member 120 backward.

At this time, if the rod member 120 is moved backward after the cell collection part 122 is completely inserted into the insertion tube 110, the rod member 120 is moved backward A suction force is generated at the front end of the insertion tube 110, and the cells C1 cut by the suction force are sucked into the insertion tube 110. At this time, stronger suction force can be obtained as the front end of the insertion tube 110 is closely attached to the cervix 10. The practitioner continues to retract the rod member 120 and at the same time, the insertion tube 110 is moved back and forth to slightly change the position in the cervix 10, and the remaining cut cells C1 around the periphery are sucked and collected. When the cut cells (C1) are collected, the inserted cells (110) are pulled by hand to pull out the cut cells (C1) of the cervix (10) taken together with the rod member (120).

By doing so, the cells C of the cervix 10 sufficient for the examination can be collected with only one procedure, and the procedure can be completed quickly and easily.

In addition, since the cleaved cells (C1) of the cervix 10 have been safely inserted into the insertion tube 110 and are drawn out of the body, contamination due to contact with the body part is intrinsically blocked. Therefore, the test reliability is greatly improved.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
