Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gynecological tumor sampler. Background Art

[0002] A tumor refers to a new growth formed by the proliferation of local tissue cells under the action of various tumorigenic factors. Because this new growth is mostly a space-occupying, block-like protrusion, it is also called a growth. Studies have found that tumor cells will exhibit metabolic changes different from normal cells. At the same time, tumor cells themselves can adapt to changes in the metabolic environment by switching between glycolysis and oxidative phosphorylation.

[0003] Common gynecological tumors include vulvar tumors, vaginal tumors, uterine tumors, ovarian tumors and fallopian tube tumors. Uterine and ovarian tumors are more common, while vulvar and fallopian tube tumors are rare. Before treating patients, it is necessary to sample and analyze the tumors in order to achieve better medical and treatment effects. For sampling of common gynecological tumors, the method is usually to enter through the vagina and further penetrate into the tumor location according to the different tumors to sample. As for the current traditional sampling scheme, it is usually necessary to dilate the uterus and then scrape it. The patient is in great pain, which can easily lead to low quality of the sample and have a great impact on the results of pathological examination. Therefore, the prior art has a new type of spiral cervical canal sampler disclosed in application number CN202321693836.5, which relates to the field of gynecological tool technology, including In summary: a sampling mechanism, wherein a spiral structure is provided at the upper end of the sampling mechanism, and after entering the cervical canal in a straight line, the sampling mechanism scrapes the inner wall of the cervical canal to obtain a cell tissue specimen, and the cell tissue specimen is stored through the spiral structure; a connecting structure is provided at the upper and lower ends of the sampling mechanism respectively; a guiding mechanism, wherein the guiding mechanism is connected to the upper end of the sampling mechanism through the connecting structure, and the maximum diameter of the guiding mechanism is equal to the diameter of the spiral structure, and is used for the sampling mechanism to linearly probe into the cervical canal and stretch the cervical canal so that the spiral structure can enter smoothly, thereby solving the problem that traditional cervical canal samplers are mostly spoon-shaped, with a wide scraper head, which makes it difficult to enter the cervical canal, has a large operating angle, requires uterine dilation, causes high pain to the patient, and is very likely to result in low sample quality, which has a great impact on the results of pathological examinations.

[0004] Although the above technical solution is very progressive and provides guide heads of different sizes to adapt to different patients, it still cannot be adjusted more finely according to the patient, that is, it cannot adapt to more patients, and it cannot be adjusted after entering. This will result in sampling not being performed after reaching the expected sampling position, but scratches will continue to occur and sampling will continue, so it needs to be improved.

[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] refer to Figure 1 as well as Figure 2 As shown, the gynecological tumor sampler according to the embodiment of the present invention includes a guide mechanism and a sampling mechanism. The sampling mechanism includes a sampling frame 11 and a sampling air bag 12 sleeved on the outside of the sampling frame 11. The outer surface of the sampling air bag 12 is provided with a thread 13;

[0032] The guide mechanism includes a guide skeleton 21, a guide head 22 and an expansion airbag 23. The guide head 22 is fixedly connected to the other end of the guide skeleton 21. The guide skeleton 21 is connected to the top of the sampling skeleton 11 through a first connecting structure 51. The expansion airbag 23 is sleeved on the outside of the guide skeleton 21 and is located between the guide head 22 and the first connecting structure 51. When in a filled state, the maximum outer diameter of the expansion airbag 23 is not less than the maximum outer diameter of the sampling airbag 12.

[0033] During actual use, the expansion airbag 23 and the sampling airbag 12 are arranged in combination to adapt to different patients. After reaching the expected position, the sampling airbag 12 is inflated so that the thread 13 contacts the surface of the tumor tissue and begins to scratch to obtain tumor tissue samples. At the same time, after the sampling is completed, the size of each airbag is reduced so that it is more convenient and easy to remove from the patient's body.

[0034] In some specific embodiments of the present invention, the guide head 22 is spherical, the expansion balloon 23 is a truncated cone structure, and the generatrix of the expansion balloon 23 is an arc. The smallest outer diameter end of the expansion balloon 23 is connected to the guide head 22, and the largest outer diameter end of the expansion balloon 23 is fixedly connected to the first connecting structure 51. This design reduces stimulation to the female cervix, alleviating the patient's pain. At the same time, the expansion balloon 23 can be slowly inflated after insertion, allowing the patient to adapt. Compared with the fixed structure in the prior art, it can provide a better experience.

[0035] Specifically, in the filled state, the amount of air in the expanded airbag 23 does not necessarily have to reach the maximum value, but the busbar of the expanded airbag 23 is an arc at this time, and the center of the arc is close to the guide frame 21. Of course, when the amount of air in the expanded airbag 23 reaches the maximum value, the busbar of the expanded airbag 23 must meet the above conditions, and it is definitely in a filled state at this time.

[0036] In some specific embodiments of the present invention, the gynecological tumor sampler further includes an extension mechanism, comprising an extension balloon 31. One end of the extension balloon 31 is connected to the bottom of the sampling frame 11 via a second connecting structure 52. Specifically, the extension balloon 31 is a bellows structure. More specifically, the extension bellows extends linearly along the forward direction of the guide mechanism. The bellows structure of the extension balloon 31 ensures the stability of the extension structure during the extension process.

[0037] refer to Figure 3As shown, in order to obtain a better experience and feedback, in some specific embodiments of the present invention, the gynecological tumor sampler also includes an air pressure sensor 41, a pressure sensor 42, a controller 43 and a power supply 44; the controller 43 is respectively connected to the air pressure sensor 41, the pressure sensor 42 and the power supply 44; the pressure sensor 42 is respectively arranged on the outer surface of each airbag, and the air pressure sensor 41 is respectively arranged in each airbag.

[0038] Preferably, each airbag is connected to the inflation drive mechanism via a corresponding air tube. Each airbag is inflated via independent air tubes, enabling independent control. The inflation drive mechanism can be a manual squeezer for ease of use. Of course, if combined with automated feedback, the inflation drive mechanism is preferably an air pump 45. In this case, the inflation drive mechanism is connected to a controller 43 and a power supply 44.

[0039] Through the above design, the filling degree of each airbag can be controlled according to the pressure feedback obtained by the pressure sensor 42. For example, when the internal air pressure of each airbag reaches the corresponding threshold, the air pump 45 is controlled to stop inflating the airbag; and when the pressure sensor 42 on the outer surface of each airbag obtains a pressure exceeding the corresponding threshold, the air pump 45 is controlled to stop inflating or deflating the airbag, so that the patient can slowly adapt.

[0040] In some specific embodiments of the present invention, the gynecological tumor sampler further includes a stimulation mechanism (not shown in the figure), which is connected to the controller 43 and the power supply 44, respectively. Specifically, the stimulation mechanism is arranged on the outer surface of each airbag. Preferably, the stimulation mechanism can generate a stimulation signal that imitates bioelectricity. More specifically, the stimulation mechanism includes an electrical stimulation mechanism, which includes an electrode sheet, which promotes muscle contraction by generating electrical stimulation, stimulates the contraction of the muscles near the vagina and the cervix, so that after each airbag expands the vagina, it can facilitate better scraping of the thread 13 on the sampling mechanism. The specific structure of the electrical stimulation mechanism is a prior art, which has been maturely applied today, and is not the core improvement of this application, so it will not be described here.

[0041] refer to Figure 4As shown, in some specific embodiments of the present invention, the first connecting structure 51 and the second connecting structure 52 each include a housing 53 and a turntable 54 rotatably connected to the housing 53. The housings 53 of the first connecting structure 51 and the second connecting structure 52 are both provided with openings and are arranged opposite each other. The turntables 54 are respectively disposed within the corresponding housings 53. The two ends of the sampling skeleton 11 are respectively fixedly connected to the turntables 54. The two ends of the sampling airbag 12 are respectively connected to the two turntables 54. The housing 53 of the second connecting structure 52 is located on one side of the extension airbag 31 and is connected to a motor 60. The motor 60 is disposed in the extension airbag 31. The output shaft of the motor 60 extends into the expansion airbag 23 and passes through the turntable 54 before being fixedly connected to the bottom of the sampling skeleton 11. Through the above design, the entire sampling mechanism can be driven to rotate by the motor 60 to achieve scratching, while the other structures remain stationary, greatly reducing the patient's discomfort.

[0042] It should be noted that the air pressure sensor 41, pressure sensor 42, controller 43, power supply 44, air pump 45 and motor 60 can all be obtained by referring to reference books to obtain corresponding models according to the actual parameters required and purchased on the market. Their specific structures and principles will not be repeated here.

[0043] Working principle:

[0044] After disinfecting the entire gynecological tumor sampler, apply lubricant, then insert the guide head of the guide mechanism into the vagina. During the process of slowly inserting, the expansion balloon 23 is also slowly inflated until the entire guide mechanism is inserted into the vagina. At this time, the sampling mechanism as a whole enters the vagina very easily, and then the extension mechanism enters the vagina. At this time, the sampling balloon 12 is deflated to shrink. Since the expansion balloon 23 and the extension balloon 31 play a supporting role, the sampling balloon 12 will no longer contact the inner wall of the vagina. Then, the extension balloon 31 is slowly inflated and deflated to allow the patient to adapt to the depth of the gynecological tumor sampler, and the expansion balloon 23 is slowly inflated and deflated to allow the patient to adapt to the degree of expansion, so that the sampling mechanism reaches the position where sampling is required while reducing stimulation to the patient. At this time, the sampling airbag 12 is inflated so that the thread 13 on the sampling airbag 12 can fully contact the tumor tissue, and the entire gynecological tumor sampler is rotated to scratch the tumor tissue to achieve sampling, or in the case of a motor 60, the sampling airbag 12 is driven by the motor 60 to rotate for sampling. After the sampling is completed, the sampling airbag 12 is deflated until the outer diameter of the sampling airbag 12 is smaller than the outer diameter of the expansion airbag 23 and the outer diameter of the extension airbag 31. The tumor tissue sample will be adhered to the thread 13 and the outer surface of the sampling airbag 12 due to the presence of the lubricating fluid and the thread 13. The entire gynecological tumor sampler is slowly withdrawn. During the withdrawal process, the expansion airbag 23 is slowly deflated to further reduce irritation to the patient. After the entire gynecological tumor sampler is completely withdrawn, the sampling is completed.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
