[0002] The cervical sampling process is generally carried out in the following steps: After adjusting the patient's position, insert the speculum, open the vagina, expose the cervix, observe the cervix with the naked eye, and remove excess mucus and other secretions.

[0003] When performing the above steps, the dilator speculum and the sampler are separated from each other, and the user needs to operate them in two steps. In addition, the sampler is suspended in the space opened by the dilator speculum when taking samples. The quality of the sample taken depends entirely on the operator's own experience. For novices, the process of taking samples with a handheld sampler may be affected by human factors such as tension and excitement, resulting in inaccurate sampling positions and unsatisfactory sampling results. Therefore, it is necessary to design a dilator speculum structure that can facilitate the operator to accurately and quickly locate the sampling position. Utility Model Content

DETAILED DESCRIPTION

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0029] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0030] The utility model provides Figure 1 - Fig. 9The cervical dilatation speculum with sampling function shown in the figure comprises several main parts, namely, a dilator 1, a reference platform 2, a ferrule 3, a sampler 4 and a movable part 5, wherein the dilator 1 is the most basic structure of the dilator speculum, and the upper plate 11 and the lower plate 12 are rotatably connected, and the upper plate 11 and the lower plate 12 can be opened after being inserted into the vagina to achieve the purpose of dilating the vagina. The reference platform 2 is used to build a placement platform on the dilator 1 so that the sampler 4 can be adjusted in position based on the placement platform, thereby stabilizing the position of the sampler 4.

[0031] Specifically, the sampler 4 includes a handle 41, a central axis 42, a scraper 43, and a brush head 44. The handle 41 and the central axis 42 are connected by a breaking point. The scraper 43 is sleeved on the central axis 42. A conical brush head 44 is fixed to the end of the central axis 42. There is sliding damping between the central axis 42 and the scraper 43. When the position of the scraper 43 on the central axis 42 needs to be adjusted, the operator needs to manually apply a directional force to the central axis 42 for adjustment. The two sides of the scraper 43 are used to scrape samples from the side wall of the vagina, and the end of the scraper 43 is used to scrape samples at the edge of the external os of the cervix. The sampler 4 is used to go deep into the external os of the cervix for sampling. This method makes it easy to adjust the position between the brush head 44 and the scraper 43. When the central axis 42 is set close to the brush head 44, the sampler 4 can collect samples from the inside of the external os of the cervix, the edge of the external os of the cervix, and the inner wall of the vagina. When the central axis 42 and the brush head 44 are far apart, the end of the scraper 43 cannot collect samples from the edge of the external os of the cervix when the brush head 44 is inserted into the cervical os. Therefore, only samples from the inside of the external os of the cervix and the inner wall of the vagina can be collected at this time.

[0032] Example 1

[0033] The movable part 5 is a ball bearing, and the reference platform 2 includes a support ring 21, a driven ring 22, a tenon 24, and a mortise 23. The tenon 24 is fixed on the dilator 1. The support ring 21 is provided with a mortise 23 that can be snap-fitted with the tenon 24. The support ring 21 is movably connected with the driven ring 22 through the movable part 5, and the driven ring 22 is fixedly connected with the ferrule 3. The handle 41 penetrates the ferrule 3 and is connected to the ferrule 3 through the breaking point. With this connection method, the movable part 5 can be used as the basis for movement, and the sampler 4 placed in the ferrule 3 can use the ferrule 3 as the reference point. After the dilator 1 penetrates into the vagina and opens, the sampler 4 can sample the designated position in the vagina in the conical space. Because of the presence of the reference platform 2 here, the operator can place the sampler 4 on it, reducing the probability of inaccurate sampling position caused by shaking of the sampler 4.

[0034] Example 2

[0035] The movable part 5 is a flexible rod that can undergo a certain torsional deformation under the drive of torsional stress. The reference platform 2 includes a support ring 21, a tenon 24, and a mortise 23. The tenon 24 is fixed on the dilator 1. The support ring 21 is provided with a mortise 23 that can be snap-connected with the tenon 24. The ferrule 3 is placed in the support ring 21. The two sides of the ferrule 3 are connected to the support ring 21 through the symmetrically arranged movable parts 5. The handle 41 passes through the ferrule 3 and is connected to the ferrule 3 through the breaking point. With this connection method, the movable part 5 can be used as the basis for the activity. The sampler 4 placed in the ferrule 3 can use the ferrule 3 as the reference point. After the dilator 1 penetrates into the vagina and opens, the sampler 4 can sample the designated position in the vagina in the conical space. Because of the presence of the reference platform 2 here, the operator can place the sampler 4 on it, reducing the probability of inaccurate sampling position caused by shaking of the sampler 4.

[0036] Compared with Example 2, Example 1 has a larger movable space for the sampler 4 and a higher applicability.

[0037] Example 3

[0038] The movable member 5 is a flexible rod that can undergo a certain torsional deformation under the drive of torsional stress. The tenon 24 is fixed to the upper plate 11, and the end of the movable member 5 is provided with a mortise hole 23 that can be snap-fitted with the tenon 24. The upper plate 11 is detachably connected to the reference platform 2 and the ferrule 3, and the ferrule 3 and the handle 41 are connected through a breaking point.

[0039] Preferably, the movable member 5 is a straight cylindrical rod. The two movable members 5 are symmetrically placed on both sides of the ferrule 3, and the ferrule 3 can only be flipped and swung in a direction perpendicular to the axis of the movable member 5, which improves the stability of the ferrule 3 and also improves the mobility of the ferrule 3 in a certain direction.

[0040] Preferably, the movable member 5 is a rod with an angle. The two movable members 5 are symmetrically placed on both sides of the ferrule 3. At this time, the ferrule 3 can not only flip and swing along the direction perpendicular to the axis of the movable member 5, but also move in other directions within the deformation range of the movable member 5, which greatly improves the stability of the ferrule 3 without reducing the stability of the ferrule 3 too much.

[0041] Compared with Example 1, Example 2 and Example 3 have a better field of view and are more conducive to the operator's sampling operation.

[0042] Of course, for the material selection of the driven coil 22 in Example 1, a transparent material can be selected. Furthermore, the driven coil 22 can be processed into a lens form with a magnifying effect.

[0043] In Example 1, Example 2, and Example 3, the characteristic of the so-called breaking point is a connecting protrusion that breaks under torsional stress. Specifically, the ferrule 3 and the handle 41 are connected by the breaking point, and the handle 41 and the central axis 42 are connected by the breaking point. At the beginning of use, the reference platform 2, the movable part 5, and the sampler 4 can be stored together in a dust-free bag and taken out when needed. When taking it out, the operator first pinches the handle 41, and breaks the breaking point between the handle 41 and the ferrule 3 by twisting the handle 41. At this time, the sampler 4 can be sampled relative to the ferrule 3. After the sampling is completed, the sampler 4 is inserted into the test tube, and then a shear force is applied to the handle 41 to break the handle 41 along the axial direction perpendicular to the handle 41. After discarding the handle 41, the test tube containing the central axis 42, the scraper 43, and the brush head 44 is sealed to complete the packaging of the sample.

[0044] Of course, before breaking off the handle 41, the samples on the scraper 43 and the brush head 44 can be retained and processed separately. Since the operation method is based on a specific situation as an example, this application will not go into details here.

[0045] In summary, the technical solution of the present application can be briefly described as follows: a reference table 2 is installed on the expander 1, the sampler 4 is placed on the reference table 2, and the reference table 2 is used as a fulcrum to move the sampler 4. On the one hand, the mobility of the sampler 4 is not reduced, and on the other hand, the stability of the operator when moving the sampler 4 is improved, the probability of erroneous sampling is reduced, and the accuracy of sampling and the convenience of operation are improved.

[0046] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
