Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical auxiliary instrument design, concretely relates to a cervical uterine cavity cell brush. BACKGROUND

[0002] For the pathological examination of cervical and uterine cavity exfoliative cell examination, the corresponding cell brush needs to be used to collect uterine exfoliative cells. The cell brush disclosed in the prior art is more for collecting cells at the cervical position, which realizes the collection of exfoliative cells in the contact area by setting the soft hair on the front section of the brush rod to contact the inner wall of the cervix. In the specific operation, the soft hair can also be used to extend into the uterine cavity to collect some exfoliative cells on the uterine cavity wall. However, since the cell brush does not set corresponding soft hair on the front end of the brush rod, the exfoliative cells in the area corresponding to the uterine cavity wall at the position cannot be fully collected. For example, the patent document with the application number CN201420720356 discloses a disposable inverted cone-shaped double-cannula cervical uterine cavity cell brush, which has the above-mentioned defects. In order to overcome the above-mentioned defects, the patent document with the application number CN201420177587.9 discloses a cervical liquid-based cell brush, which has a part of the brush at the end of the brush rod. However, the length extension direction of the bristles of this part of the brush extends along the length direction of the rod body of the brush rod. When it is necessary to collect the exfoliative cells of the uterine cavity wall corresponding to the end of the brush rod, the operator needs to apply force to the uterine cavity wall along the axial direction (i.e. the length extension direction) of the brush rod. The free end of this brush will directly contact the uterine cavity wall, which may stimulate or even harm the uterine cavity wall. Therefore, the comfort of the patient during medical treatment is reduced. SUMMARY

[0003] Therefore, the technical problem to be solved by the utility model is to provide a cervical uterine cavity cell brush, which can effectively collect the exfoliative cells in the area corresponding to the uterine cavity wall at the position of the first end of the brush rod, avoid stimulating the patient's uterus, and improve the comfort of the patient during medical treatment.

[0004] In order to solve the above-mentioned problems, the utility model provides a cervical uterine cavity cell brush, which comprises a brush rod, the brush rod has a first end and a second end, wherein when the cervical uterine cavity cell brush is in the use state, the first end is in the cervix or uterine cavity, the second end is outside the cervix or uterine cavity, the brush rod is provided with a first brush composed of a plurality of first bristles on the peripheral wall of the rod body close to the first end, the first brush is arranged around the brush rod, the first end is provided with a second brush composed of a plurality of second bristles, each second bristle comprises a first segment and a second segment which are bent into an L shape, wherein the first segment is connected with the first end, and the extension direction of the first segment is parallel to the length extension direction of the brush rod.

[0005] In some embodiments, the free end of each of the first and second bristles is semi-spherical.

[0006] In some embodiments, the bending position of the second bristle is semi-circular.

[0007] In some embodiments, the length of the second section of the second bristle is greater than the length of the first section.

[0008] In some embodiments, the first brush is a circular truncated cone, and the large-diameter end face of the circular truncated cone is between the small-diameter end face of the circular truncated cone and the first end face.

[0019] Referring to Figures 1 to 3 As shown, according to the embodiment of the present application, a cervical cavity cell brush is provided, comprising a brush rod 1, the brush rod 1 having a first end and a second end, wherein when the cervical cavity cell brush is in a use state, the first end is in the cervix or the uterine cavity, and the second end is outside the cervix or the uterine cavity, a first brush 2 composed of a plurality of first bristles (not labeled in the figure) is arranged on the outer peripheral wall of the rod body adjacent to the first end of the brush rod 1, the first brush 2 is arranged around the brush rod 1, a second brush 3 composed of a plurality of second bristles (not labeled in the figure) is arranged on the first end, each of the second bristles comprises a first segment and a second segment bent into an L shape, wherein the first segment is connected to the first end, and the extension direction of the first segment is parallel to the length extension direction of the brush rod 1. In the specific use process, the aforementioned first brush 2 can be used to collect the exfoliated cells on the inner wall of the cervix and the uterine cavity, and the second brush 3 is used to collect the exfoliated cells in the region corresponding to the end of the first end of the brush rod 1 and the end of the brush rod 1, thereby realizing the all-around collection of the exfoliated cells in the cervix and the uterine cavity and ensuring the accuracy of the test results.

[0020] In the technical solution, the second brush composed of the second bristles bent into an L shape is arranged at the first end of the brush rod 1, which can increase the contact area with the uterine cavity wall, ensure the cell collection effect, and significantly reduce the stimulation or even harm caused by the brush perpendicular to the uterine cavity wall, thereby improving the medical comfort of the patient.

[0021] The aforementioned brush rod 1 can be a nylon rod, which has the advantage of low manufacturing cost, thereby meeting the one-time use working condition requirement of the cervical cavity cell brush of the present application. At this time, each bristle can be connected to the outer side of the nylon rod in a pasting manner. Of course, in other feasible embodiments, the aforementioned brush rod 1 can be realized by weaving metal wires, and each bristle is clamped and connected in the weaving gap.

[0022] In a preferred embodiment, the free end of each of the first bristles and the second bristles is hemispherical, so that the free end of each bristle is a more smooth structure, preventing damage to the inner wall of the cervix or the uterine cavity.

[0023] In another preferred embodiment, the bending position of the second bristle is semicircular bending, preventing the bending position from forming a sharp corner structure, and further reducing the damage to the cervix or the uterine cavity of the user during the collection of the cells.

[0024] As a preferred implementation, the length of the second segment of the second bristle is greater than the length of the first segment, so as to ensure that the force along the axial direction of the brush rod 1 can be more effectively transmitted to the second segment through the first segment, ensuring the contact of the second segment with the cavity wall of the uterine cavity, and thus ensuring the effectiveness of cell collection.

[0025] Specifically referring to Figure 1 As shown, in some embodiments, the first brush 2 is a circular truncated cone, and the large-diameter end face of the circular truncated cone is between the small-diameter end face and the first end face, that is, the first brush 2 forms an inverted circular truncated cone structure in appearance, which can be roughly matched with the shape of the uterine cavity and cervix, thereby facilitating the efficient collection of exfoliated cells on the wall surface.

[0026] As a more preferred embodiment, the cervical uterine cavity cell brush further comprises a sleeve 4, which is gap-fitted on the radial outer side of the brush rod 1, that is, there is an annular accommodating ring cavity between the sleeve 4 and the brush rod 1, which can accommodate the first brush 2 in it to form protection when the cell collection is completed.

[0027] In order to ensure that the first brush 2 can enter the sleeve 4 more smoothly, a flared groove 41 is formed on the end face of the sleeve 4 close to the first end, and the large opening of the flared groove 41 faces the first end side, as shown in Figure 2 As shown, the port diameter of the flared groove 41 becomes smaller and smaller from the first end to the second end, thereby forming a guide for the first brush 2 to enter the aforementioned accommodating ring cavity, and the operation of the operator is more smooth.

[0028] Since the setting area of the second brush 3 is much smaller than that of the first brush 2, in order to ensure the sufficient collection of cells in the area of the uterine cavity corresponding to the second brush 3, it is preferred that the setting density of the second bristles in the second brush 3 is greater than that of the first bristles in the first brush 2.

[0029] Specifically referring to Figure 3 As shown, the second end of the brush rod 1 is detachably connected with a handheld force applying member 5, and the aforementioned handheld force applying member 5 is, for example, a circular truncated cone solid member which can be in interference fit with the second end of the brush rod 1, and the diameter of the solid member is greater than that of the brush rod 1, thereby facilitating the operator to twist it with the thumb and index finger to rotate and thus drive the reciprocating rotation of the aforementioned first brush 2 and second brush 3 to collect cells.

[0030] Those skilled in the art can easily understand that the above advantageous modes can be freely combined and superimposed without conflict.

[0031] The above merely is the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is merely the preferred embodiment of the present application, and it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principle of the present application, a number of improvements and modifications can be made, and these improvements and modifications shall be considered as the protection scope of the present application.
