Description

Technical Field

[0001] The present invention particularly relates to an inspection sampling device. Background Art

[0002] The endometrium is the lining of the uterus. An endometrial biopsy is a procedure in which a sample of tissue is removed for testing. A biopsy can be used to screen for cancer or precancerous cells, determine the cause of irregular bleeding, investigate fertility problems, check for infection, or monitor the effectiveness of certain medications.

[0003] The specific operation of the existing endometrial biopsy sampling is: put a vaginal speculum in the vagina, open the vaginal speculum and keep it open, insert a spoon-shaped scraper from the vaginal speculum, insert it into the uterus from the cervix after passing through the vagina, and press the end of the scraper against the inner wall of the uterus, then pull the scraper outward to scrape the surface tissue of the endometrium into the scraper, then take out the scraper and examine the hanging tissue sample.

[0004] This method has the following disadvantages:

[0005] 1. During the sampling process, the force of the spatula pressing against the inner wall of the uterus depends entirely on the operator's experience, which can easily lead to the pressing depth being too deep or too shallow. When the pressing depth is too shallow, it will lead to insufficient single sampling; when the pressing depth is too deep, it is easy to cause damage to the inner wall of the uterus;

[0006] 2. When scraping with a spatula, sampling can only be performed when the spatula opening is facing upwards. When the spatula opening is facing downwards, sampling cannot be performed because the sample cannot be stored. This will inevitably increase the limitations of sampling.

[0007] 3. Since the opening of the scraper is in an open state, during the sampling process, the tissue inside the scraper is easy to fall out of the scraper. If the tissue carries cancer cells or other viruses, it is easy to cause the spread of the disease. Summary of the invention

[0008] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an inspection sampling device, which can conveniently control the sampling depth during the sampling process to achieve on-demand sampling, and at the same time, can avoid arbitrary falling of tissues and reduce damage to the endometrium.

DETAILED DESCRIPTION

[0032] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0033] See also Figures 1 to 5 The present invention provides an inspection sampling device, including an operating rod 100 and a sampling member 200.

[0034] Specifically, one end of the operating rod 100 is an operating end, and the other end is an insertion end. The insertion end can be inserted into the uterus and moved in the uterus. The sampling member 200 includes a sampling barrel 210, a scraper assembly 220, a driving assembly 230 and a positioning member 240. The sampling barrel 210 is arranged at the insertion end and can temporarily store endometrial tissue. The scraper assembly 220 is arranged in the sampling barrel 210, and the blade of the scraper assembly 220 is exposed at the end of the sampling barrel 210; the driving assembly 230 is connected to the scraper assembly 220, and can drive the scraper assembly 220 to cut the endometrium by rotation; the positioning member 240 is arranged on the sampling barrel 210, and the sampling barrel 210 is pressed against the inner wall of the uterus through the positioning member 240, and the positioning member 240 can make the endometrial tissue of a quantitative height contact with the blade of the scraper assembly 220.

[0035] When in use, a vaginal dilator is placed in the vagina to dilate the vagina. Then, the tail end of the operating rod 100 is held by hand, and the insertion end and the sampling piece 200 are inserted into the uterus from the cervix after passing through the vagina. Then, the operating rod 100 is pressed to press the positioning piece 240 against the inner wall of the uterus. At this time, the endometrial tissue of a certain height can contact the blade of the scraper assembly 220. Then, the scraper assembly 220 is driven to rotate by the driving assembly 230. The scraper assembly 220 cuts off the endometrial tissue of a certain height in contact with it, and the detached endometrial tissue is temporarily stored in the sampling tube 210. After the sampling is completed, the operating rod 100 and the sampling piece 200 can be taken out together.

[0036] By using the above-mentioned inspection sampling device, samples can be taken at any position in the uterus. At the same time, during the sampling process, the sampling depth can be conveniently controlled to achieve the purpose of sampling on demand and reducing damage to the endometrium. In addition, by temporarily storing the removed tissue in the sampling tube 210, the virus transmission caused by the tissue falling arbitrarily can be avoided.

[0037] In this embodiment, the scraper assembly 220 includes a mounting plate 221 and a plurality of scrapers 222. The plurality of scrapers 222 are arranged on the mounting plate 221 at intervals in the circumferential direction. The mounting plate 221 is rotatably arranged in the sampling tube 210. The driving assembly 230 is connected to the mounting plate 221 and can drive the mounting plate 221 to rotate. When the mounting plate 221 rotates, the scrapers 222 can be driven to rotate, thereby cutting off the endometrial tissue.

[0038] In this embodiment, the positioning member 240 includes a cover plate, which is arranged at the end of the sampling tube 210. The blade of the scraper 222 can rotate against the inner wall of the cover plate. A plurality of through holes are provided at intervals on the cover plate. When the cover plate is pressed against the inner wall of the uterus, the endometrial tissue can be squeezed into the through holes. In a specific implementation, the endometrial tissue squeezed into the cover plate can be controlled by the size of the through hole. For example, when the hole is large, the height of the tissue squeezed into the cover plate becomes higher. When the aperture of the through hole is reduced, the height of the endometrial tissue squeezed into the cover plate is correspondingly reduced. When the blade of the scraper 222 rotates against the inner wall of the cover plate, the endometrial tissue of a certain height can be cut off.

[0039] In this embodiment, the sampling cylinder 210 includes a cylinder 211 and a storage bin 212. The cylinder 211 is connected to the operating rod 100, and a discharge hole communicating with the inner cavity of the cylinder 211 is provided on the cylinder 211. A detachable cover of the storage bin 212 is provided on the discharge hole. When the material in the cylinder 211 rotates, it can fly into the storage bin 212 from the discharge port. During the cutting process of the scraper assembly 220, the cut endometrial tissue pushes the scraper 222 to rotate together. When it rotates to the discharge hole, it enters the storage bin 212 under the action of centrifugal force. After the inspection sampling device is taken out, the storage bin 212 can be removed, and the endometrial tissue in the storage bin 212 can be poured out.

[0040] In this embodiment, the driving assembly 230 includes a rotating power source 231 and a rotating shaft 232. The rotating power source 231 is disposed in the sampling tube 210, and the rotating shaft 232 is connected to the rotating power source 231. The rotating power source 231 can drive the rotating shaft 232 to rotate, and the mounting plate 221 is sleeved and fixed on the rotating shaft 232. In a specific implementation, the rotating power source 231 can preferably be a micro rotating motor.

[0041] As a preferred embodiment, the device further comprises a material guide 300, which is used to guide the endometrial sample cut by the scraper assembly 220 into the material outlet.

[0042] Specifically, the material guide member 300 includes a material guide disc 310 and a material guide plate 320. The material guide disc 310 is sleeved and fixed on the rotating shaft 232, and there are multiple material guide plates 320, which are evenly spaced circumferentially arranged on the material guide disc 310, and the outer side of the material guide plate 320 is offset in the forward direction.

[0043] During the cutting process, when the mounting plate 221 and the scraper 222 rotate, since the guide disc 310 and the guide plate 320 are fixed, part of the splashed tissue can be guided back to the discharge hole.

[0044] As a preferred embodiment, the device further includes a protective cover 400. The protective cover 400 is sleeved on the operating rod 100, and can move along the operating rod 100 and sleeved on the sampling member 200. During the in and out process, when the protective cover 400 is sleeved on the operating rod 100 and the sampling member 200, it is convenient to insert or remove the sampling device for rectification and inspection.

[0045] Specifically, the protective sleeve 400 includes a sleeve 410, an elastic membrane 420, and a plurality of elastic rods 430. The sleeve 410 can be slidably mounted on the operating rod 100. The plurality of elastic rods 430 are arranged at intervals along the circumference of the operating rod 100, and all the elastic rods 430 are fixedly connected to the sleeve 410. An elastic membrane 420 is arranged between each two adjacent elastic rods 430, and a ball is arranged on the end of each elastic rod 430 close to the insertion end.

[0046] During use, all the elastic rods 430 can be driven forward or backward by the driving sleeve 410, so that the sampling member 200 can be exposed or stored in the protective cover 400, which facilitates the placement or removal of the entire device.

[0047] As another preferred embodiment, the device further comprises a guide block 500, which is disposed between the operating rod 100 and the sampling tube 210, and the outer wall of the guide block 500 is gradually inclined from the end of the sampling tube 210 toward the operating rod 100. The guide block 500 facilitates the smooth forward or backward movement of the protective cover 400.

[0048] The above inspection sampling device is used as follows:

[0049] During use, with the protective cover 400 sleeved on the outside of the operating rod 100 and the sampling piece 200, a vaginal dilator is placed in the vagina to dilate the vagina. Then, the tail end of the operating rod 100 is held by hand, and the insertion end and the sampling piece 200 are inserted into the uterus from the cervix after passing through the vagina. Then, the sleeve 410 is pulled backward until the sampler is exposed. Then, the operating rod 100 is pressed to press the cover plate against the inner wall of the uterus. Then, the entire device is moved along the inner wall of the uterus. At this time, endometrial tissue of a certain height can enter the cover plate from the through hole. Then, the rotating power source 231 is started to drive the scraper assembly 220 to rotate. The scraper 222 cuts off the endometrial tissue of a certain height in contact with it, and the detached endometrial tissue is thrown into the storage bin 212. After sampling is completed, the operating rod 100 and the sampling piece 200 can be taken out together.

[0050] By using the above-mentioned inspection sampling device, samples can be taken at any position in the uterus. At the same time, during the sampling process, the sampling depth can be conveniently controlled to achieve on-demand sampling and reduce damage to the endometrium. In addition, by temporarily storing the removed tissue in the sampling tube 210, the virus transmission caused by the tissue falling randomly can be avoided.
