Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an endometrial sampler. Background Technology

[0002] An endometrial sampler is a medical device commonly used in obstetrics and gynecology, assisted reproductive technology, and contraceptive devices. Its main function is to obtain endometrial tissue samples for pathological examination or other diagnostic purposes. This technology is of great significance for the early diagnosis and treatment of gynecological diseases, especially playing a key role in the screening and diagnosis of diseases such as endometrial cancer and endometriosis.

[0003] Currently, curettage is the commonly used method for endometrial pathology testing in clinical practice. However, medical staff often struggle to control the pressure when using the curette, easily applying excessive force and causing damage to the uterine wall. In severe cases, this can lead to uterine perforation, massive bleeding, and even death. Furthermore, when removing samples with the curette, the sample is prone to detaching, resulting in ineffective collection and poor sampling quality. The procedure is also difficult for medical staff. While endometrial cell collection devices are available on the market, these devices can only collect samples from a portion of the endometrium, resulting in unrepresentative specimens and insufficient sample volume, leading to inaccurate test results. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an endometrial sampler to solve the problems of easy damage to the uterus and incomplete sampling in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides an endometrial sampler, including a sleeve, a trachea, and an air bag. The trachea is movably fitted inside the sleeve, and the sleeve and the trachea are detachably connected. The trachea extends through the sleeve to the outside, and one end of the trachea is fixedly connected to the air bag. The outer wall of the air bag is provided with bristles in a radial pattern.

[0006] Optionally, the end of the trachea abuts against the top of the inner wall of the airbag.

[0007] Optionally, the top diameter of the airbag is larger than the bottom diameter.

[0008] Optionally, the sleeve and the air tube are detachably connected by a limiting member;

[0009] The limiting component is a ring with an opening, and the inner wall of the ring is interference-fitted with the outer wall of the trachea.

[0010] The bottom of the ring is provided with a retaining ring, which extends into the sleeve. The outer wall of the retaining ring is interference-fitted with the inner wall of the sleeve. The bottom of the retaining ring has an inclined surface that slopes outward.

[0011] Optionally, the limiting member is installed at both ends of the sleeve.

[0012] Optionally, the maximum diameter of the airbag when it is not inflated is smaller than the inner diameter of the sleeve.

[0013] Optionally, the air pipe is equipped with an air valve.

[0014] Optionally, the trachea is a copper tube.

[0015] Optionally, the trachea is equipped with a pressure gauge to provide feedback on the inflation level of the airbag.

[0016] Optionally, the outer wall of the sleeve is provided with scale lines.

[0017] As described above, the endometrial sampler of this utility model has at least the following beneficial effects:

[0018] 1. This utility model uses the bristles on the airbag to take samples, avoiding damage to the uterine cavity wall. The shape of the airbag can adapt to the shape of the uterine cavity. When taking samples with the bristles, the mucosa on the entire uterine cavity wall can be brushed, making the sampling more comprehensive and accurate, and ensuring the validity and accuracy of the test results.

[0019] 2. This utility model detachably connects the trachea and sleeve by setting a limiting component, which facilitates the removal of the trachea and balloon from the sleeve, avoids contamination of the bristles by body fluids by mucosal fragments, and allows adjustment of the fixed position of the trachea and sleeve to ensure the stability of the trachea within the sleeve and prevent slippage. Furthermore, the trachea is malleable, allowing the length and angle of the trachea extension to adapt to the uterine cavity of different patients, avoiding damage to the uterus and ensuring more complete sampling. At the same time, it facilitates cleaning and replacement of parts, improving the hygiene and service life of the equipment.

[0020] 3. The air valve on the trachea in this utility model can ensure that the air bag will not leak during the sampling process. After the sampling is completed, the air valve can be opened to release the air. When the trachea is removed, the sample on the brush bristles will be less likely to be rubbed off. It also makes it easier to insert and remove the trachea, reducing patient discomfort and pain. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Please see Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0030] Please see Figures 1 to 4 This utility model provides an endometrial sampler, including a sleeve 1, a trachea 2, and an air bag 3. The trachea 2 is movably fitted inside the sleeve 1. The sleeve 1 and the trachea 2 are detachably connected for easy cleaning and replacement of parts. The trachea 2 extends through the sleeve 1 to the outside. One end of the trachea 2 is fixedly connected to the air bag 3, and the other end of the trachea 2 is connected to an inflation device to inflate the air bag 3. The outer wall of the air bag 3 is provided with radially arranged bristles 4, which can gently scrape endometrial tissue and reduce patient discomfort.

[0031] In this embodiment, the end of the trachea 2 abuts against the top of the inner wall of the airbag 3, ensuring a tight connection between the trachea 2 and the airbag 3. This also facilitates the insertion of the airbag 3 into the uterus during sampling, ensuring the correct position of the airbag 3 within the uterus. The top diameter of the airbag 3 is larger than its bottom diameter, making the airbag 3 inflated into an inverted cone shape, which better conforms to the structure of the uterine cavity, allowing for the brushing of mucosal fragments throughout the uterine cavity, resulting in more comprehensive and accurate sampling. The maximum diameter of the airbag 3 when deflated is smaller than the inner diameter of the sleeve 1, ensuring that the airbag 3 can pass smoothly through the sleeve 1, preventing the sample on the bristles 4 from being contaminated by bodily fluids, and avoiding the rubbing off of mucosal fragments on the bristles 4, which could lead to insufficient sampling.

[0032] In this embodiment, please refer to Figures 2 to 3 The sleeve 1 and the air tube 2 are detachably connected by a limiting member 5. The limiting member 5 is a ring with an opening for easy installation and disassembly. The inner wall of the ring is press-fitted with the outer wall of the air tube 2 to prevent the air tube 2 from moving up and down within the sleeve 1, ensuring the stability of the air tube 2 within the sleeve 1. A retaining ring 51 is provided at the bottom of the ring, extending into the sleeve 1. The outer wall of the retaining ring 51 is press-fitted with the inner wall of the sleeve 1 to further fix the position of the limiting member 5 and the air tube 2, preventing the air tube 2 from rotating within the sleeve 1, making it more stable and easier to sample. The bottom of the retaining ring 51 has a bevel that slopes outward, facilitating the insertion of the limiting member 5 into the sleeve 1. Anti-slip strips 52 are provided on both the inner wall of the ring and the outer wall of the retaining ring 51 to increase friction, make the fixation tighter, and prevent the air tube 2 from sliding within the sleeve 1.

[0033] In this embodiment, both ends of the sleeve 1 are equipped with limiting members 5, which makes the trachea 2 and the sleeve 1 more stable, prevents the trachea 2 from shaking, makes the rotation of the balloon 3 more stable during sampling, and makes the operation more convenient. In use, the trachea 2 is first fixed in the sleeve 1 with the limiting members 5 to ensure that it will not shake. After sampling, the sleeve 1 and the trachea 2 are directly removed from the patient's body as a whole. Then the limiting members 5 are removed, and the trachea 2 and the balloon 3 are taken out of the sleeve 1. Then the endometrial fragments on the bristles 4 are collected.

[0034] In this embodiment, the trachea 2 is equipped with an air valve 6 to control the inflation and deflation of the airbag 3, preventing air leakage during sampling and simplifying operation. The trachea 2 is also equipped with a pressure gauge to provide feedback on the inflation level of the airbag 3. Medical personnel can confirm the inflation level of the airbag 3 based on the pressure on the pressure gauge, ensuring that the size of the airbag 3 is sufficient to complete the sampling, or avoiding damage to the patient's uterus caused by an excessively large airbag 3. This also facilitates the doctor's control over the inflation volume of the airbag 3 and improves the accuracy of sampling.

[0035] In this embodiment, please refer to Figure 4The trachea 2 is a copper tube, which can be a soft copper tube. It is highly malleable and can be bent at various angles to adapt to different shapes of uterus. The trachea 2 can be bent and shaped according to different shapes of uterus so that the angle of the trachea 2 is equal when it is inserted into the uterus, which improves the practicality of the sampler.

[0036] In this embodiment, the outer wall of the sleeve 1 is provided with scale lines, which makes it easy for medical staff to observe the scale lines, control the length of the airbag 3 and the sampling depth, ensure the accuracy of sampling, and at the same time avoid the airbag 3 from being inserted too deeply and causing damage to the patient.

[0037] In use, first pass the trachea 2 through the sleeve 1 and fix the trachea 2 and sleeve 1 with the limiting piece 5 to ensure that the trachea 2 will not rotate. Insert the sampler into the patient's uterus. Medical staff control the length of insertion of the sampler according to the scale lines on the sleeve 1. Then connect the trachea 2 to the inflation device to inflate the balloon 3. Determine the degree of inflation of the balloon 3 according to the pressure gauge. After inflation is completed, close the air valve 6. Medical staff hold the sleeve 1 and rotate it to start sampling. After sampling is completed, open the air valve 6 to expel all the gas in the balloon 3. Remove the limiting piece 5 and take out the trachea 2 and balloon 3 from the sleeve 1. Then collect the endometrial fragments on the bristles 4 and then remove the sleeve 1 from the patient's body.

[0038] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
