Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary equipment, and in particular relates to an endometrial sampler. Background Art

[0002] Endometrial sampling is a common gynecological procedure used to obtain tissue samples from the endometrium for pathological examination. This test helps diagnose a range of uterine-related diseases, such as endometrial hyperplasia, endometritis, and endometrial cancer.

[0003] The traditional method of endometrial sampling is to use intrauterine curettage. During curettage, a metal endometrial curette is usually used. The scraper head is shaped like a digging spoon or a spoon. During the operation, the endometrial curette is inserted along the cervix to the bottom of the uterus, and several pieces are scraped from top to bottom close to the uterine wall to obtain endometrial specimens.

[0004] However, these traditional methods have some limitations. For example, intrauterine curettage is usually a relatively invasive procedure, and the process is complicated and can easily cause discomfort to the patient. In addition, the design of traditional samplers does not fully consider the need to prevent bacteria and avoid sample contamination. During the sampling process, if the sample is contaminated by cells or microorganisms from the vagina or cervix, it is easy to affect the results of pathological examinations and lead to misdiagnosis.

[0005] Therefore, the utility model provides an endometrial sampler. Utility Model Content

[0006] In order to solve the above technical problems, the utility model designs an endometrial sampler, which can simplify the operation, reduce the discomfort of patients, and ensure the quality of samples through an effective anti-contamination mechanism, thereby improving the accuracy of pathological diagnosis.

[0007] In order to achieve the above technical effects, the utility model is implemented through the following technical solutions: an endometrial sampler, including a protective tube, an antibacterial tube and a sampling tube.

[0008] Furthermore, a guide seat is provided at the upper part of the protection tube, and a threaded seat is provided at the lower part of the protection tube; the thread at the lower end of the antibacterial tube is cooperated and connected with the threaded seat of the protection tube, the opening and closing cover arranged at the upper end of the antibacterial tube is movably mounted on the guide seat, and springs are symmetrically provided on both sides of the opening and closing cover; the sampling tube is movably mounted in the internal channel of the antibacterial tube.

[0009] Furthermore, the guide seat is cylindrical, and a tapered channel is provided inside the guide seat, and the aperture of the lower end of the tapered channel is smaller than the diameter of the antibacterial tube.

[0010] Furthermore, a first limiting ring is provided below the outer surface of the antibacterial tube.

[0011] Furthermore, the tail end of the sampling tube extends out of the antibacterial tube and is fixedly connected to the handle, the tail end of the sampling tube is provided with a second limiting ring, and the head end of the sampling tube extends into the opening and closing cover and is fixedly connected to the sampling swab.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model avoids the use of a metal endometrial scraper during the sampling process, thereby reducing physical damage and stimulation to the uterus and reducing the patient's discomfort. In addition, the structural design of the sampler makes the sampling operation simpler, without the need for complicated insertion and scraping steps, and reduces the risk during the operation;

[0014] 2. In the utility model, a combination structure of a protective tube, an antibacterial tube and a sampling tube is adopted. The upper end of the antibacterial tube is designed with an opening and closing cover, which can be opened when entering the uterus and closed when exiting, ensuring that during the sampling process, the sample will not come into contact with cells or microorganisms of the vagina and cervix, thereby greatly reducing the risk of sample contamination. This not only improves the accuracy of pathological examinations, but also reduces the possibility of misdiagnosis. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figures 1 to 5 As shown, an endometrial sampler comprises a protective tube 1, an antibacterial tube 2 and a sampling tube 3. A guide seat 11 is provided at the upper part of the protective tube 1, and a threaded seat 12 is provided at the lower part of the protective tube 1. The thread at the lower end of the antibacterial tube 2 is matched and connected with the threaded seat 12 of the protective tube 1. An opening and closing cover 21 provided at the upper end of the antibacterial tube 2 is movably mounted on the guide seat 11, and springs 22 are symmetrically provided on both sides of the opening and closing cover 21; the sampling tube 3 is movably mounted in the internal channel of the antibacterial tube 2.

[0026] The guide seat 11 is cylindrical, and a tapered channel 111 is provided inside the guide seat 11 . The aperture of the lower end of the tapered channel 111 is smaller than the diameter of the antibacterial tube 2 .

[0027] A first limiting ring 23 is provided below the outer surface of the antibacterial tube 2 .

[0028] The tail end of the sampling tube 3 extends out of the antibacterial tube 2 and is fixedly connected to the handle 31 . A second limiting ring 32 is provided at the tail end of the sampling tube 3 . The head end of the sampling tube 3 extends into the opening and closing cover 21 and is fixedly connected to the sampling swab 33 .

[0029] The protective tube 1 is made of elastic material with scale marks on the outer surface, and the antibacterial tube 2 and the sampling tube 3 are also made of elastic material. The sampling swab 33 material has good adsorption properties and has tiny grooves or textures on the surface to help capture and retain tissue samples.

[0030] Example 2

[0031] When using the endometrial sampler of the utility model, the operation steps and principles are as follows:

[0032] First, ensure that all parts have been strictly disinfected. The opening and closing cover 21 is in a closed state, the protective tube 1 of the sampler is first inserted into the vagina, then gradually pushed to the cervix, and then the entire sampler is gently pushed so that it passes through the cervix and enters the uterine cavity. The medical staff rotates the antibacterial tube 2 to make it rise inside the protective tube 1. Since the lower end thread of the antibacterial tube 2 cooperates with the threaded seat 12 of the protective tube, the antibacterial tube 2 can move up steadily along the thread. As the antibacterial tube 2 rises, the opening and closing cover 21 at its upper part is guided by the tapered channel 111 inside the guide seat 11 and begins to open, thanks to the elastic effect provided by the springs 22 on both sides of the opening and closing cover. When the upper end of the antibacterial tube 2 reaches the tapered channel 111 of the guide seat 11, the antibacterial tube 2 will be limited and stop rising because the lower end aperture of the channel is smaller than the diameter of the antibacterial tube 2. The medical staff holds the handle 31 of the sampling tube 3 and pushes the sampling tube 3 along the internal channel of the antibacterial tube 2. As the sampling tube 3 is pushed forward, the sampling swab 33 on the head end thereof passes through the opened opening and closing cover 21 and enters the uterus. In order to prevent the sampling tube 3 from being pushed in too far, the second limiting ring 32 on the sampling tube 3 will limit its further entry when it contacts the antibacterial tube 2. Then the handle 31 is turned, and the sampling swab 33 also takes samples in the uterus.

[0033] After sampling is completed, the sampling tube 3 is pulled out from the interior of the antibacterial tube 2. Subsequently, the antibacterial tube 2 is rotated in the opposite direction to start moving downward. As the antibacterial tube 2 moves downward, the opening and closing cover 21 is gradually closed under the squeezing action of the conical channel 111. At the same time, the first limiting ring 23 contacts the threaded seat 12 to limit its further downward movement, ensuring that the antibacterial tube 2 is completely returned to its original position.
