Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a vaginal dilator and sampler. Background Art

[0002] A "dilator" is a medical device used for the diagnosis and treatment of female reproductive tract diseases. It is mainly used to sample cells and tissues from the cervix, endometrium, vagina, etc. for pathological examination and analysis. When using a dilator, the doctor will first give the patient local anesthesia to reduce pain and discomfort. The doctor will then insert the hysteroscope and dilator and guide them into the area where the sample needs to be collected. The dilator usually has an adjustable opening size, allowing it to adapt to different anatomical structures.

[0003] The function of the vaginal dilator is to obtain cell and tissue samples from the reproductive tract. These samples are obtained through a sampling needle and can generally be used for pathological examination, bacterial culture, virus screening, etc. By analyzing these samples, doctors can diagnose and evaluate whether the patient has diseases such as inflammation, infection, and tumors. In addition, the vaginal dilator can also be used to treat some reproductive tract diseases, such as curettage and endometrial damage repair.

[0004] It should be noted that the use of the vaginal dilator sampler requires the guidance and operation of a professional doctor to ensure the accuracy and safety of the sampling. At the same time, the patient may feel some discomfort and pain during use, but this is within the controllable range and can be alleviated with the assistance of anesthesia and analgesia.

[0005] In short, the "vaginal dilator" is a medical device used for the diagnosis and treatment of female reproductive tract diseases.

[0006] Since a general sampling needle has an opening at the tip, it is inevitable that other tissues will be taken into the sampling needle during the process of piercing the designated sampling position, and the extra tissue cells will inevitably interfere with the sample detection.

[0007] Therefore, those skilled in the art provide a vaginal dilation sampler to solve the problems raised in the above background technology. Utility Model Content

[0008] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a vaginal dilator sampler is proposed. The sampler seals the upper end of a sampling inner tube, rotates the sampling inner tube at a sampling position to obtain a tissue sample through a meat-cutting bevel, and then restores the meat-cutting bevel to a closed state, thereby effectively preventing a conventional sampling needle from collecting tissue cells from other parts into the needle during the process of inserting the needle into the tissue, thereby preventing other tissue cells from interfering with sample detection.

At this time, the puncture sleeve penetrates into the human tissue, and the closed front end of the sampling inner tube prevents the human tissue from entering the puncture sleeve. At this time, the meat cutting bevel on one side of the upper end of the sampling inner tube is blocked by the puncture sleeve, and the sampling inner tube is rotated to gradually expose the meat cutting bevel of the sampling inner tube. During the rotation, the human tissue is cut and stored inside the sampling inner tube, and then it is rotated until it is blocked by the puncture sleeve, and the sampling inner tube is pulled out to complete the sampling.

[0011] Furthermore, a buffer cavity is provided at a position of the outer sleeve near one side of the support plate, a spring plate is fixedly provided inside the buffer cavity, a latching tooth is fixedly provided at a middle position of one side of the spring plate, an annular groove is provided at the circumference of the lower end of the inner sleeve, and the latching tooth is movably clamped inside the annular groove;

[0014] With the technical solution, it is convenient to control the movement of the inner sleeve by pressing the pressing plate with the thumb when holding the handle, which is convenient for one-handed operation.

[0015] Furthermore, a rubber ball head is fixedly provided at the lower end of the sampling tube;

[0016] Through the above technical solution, negative pressure is formed inside the sampling tube during sampling, which facilitates the inhalation of samples.

[0017] Furthermore, the No. 1 vaginal expansion plate, No. 2 vaginal expansion plate and outer sleeve are all made of titanium alloy;

[0018] Through the above technical solution, the strength and lightness of use are guaranteed, and at the same time, it is not easy for bacteria to breed.

[0019] Furthermore, the handle is made of polypropylene;

[0020] Through the above technical solution, the safety of use is ensured while the weight is reduced and it is easy to grasp.

[0021] Furthermore, the outer surface of the handle is provided with a silicone anti-slip layer;

[0022] The above technical solution facilitates gripping of the handle and avoids slipping.

[0023] Furthermore, the upper ends of the No. 1 vaginal expansion plate and the No. 2 vaginal expansion plate are both rounded;

[0024] The above technical solution can avoid scratching the patient's vagina during the insertion process.

[0025] The utility model has the following beneficial effects:

[0026] The utility model provides a vaginal dilator sampler, which is easy to hold with one hand and more convenient to use. The user can hold the handle first, insert the No. 1 vaginal dilator plate, the No. 2 vaginal dilator plate and the outer sleeve into the vagina, press the inner sleeve into the outer sleeve with the thumb, and the moving inner sleeve pushes the No. 1 vaginal dilator plate and the No. 2 vaginal dilator plate through the No. 1 connecting rod and the No. 2 connecting rod to open the vagina, and then completely insert the sampling inner tube at the upper end of the sampling tube into the puncture sleeve at the upper end of the inner sleeve, insert the sampling tube into the inner sleeve, and then the puncture sleeve pierces the human tissue. The closed front end of the sampling inner tube prevents human tissue from entering the puncture cannula. At this time, the meat-cutting bevel on one side of the upper end of the sampling inner tube is blocked by the puncture cannula. The sampling inner tube is rotated to gradually expose the meat-cutting bevel of the sampling inner tube. During the rotation, the human tissue is cut off and stored inside the sampling inner tube. Then, it is rotated until it is blocked by the puncture cannula, and the sampling inner tube is pulled out to complete the sampling. This effectively avoids the collection of tissue cells from other parts of the conventional sampling needle into the needle tube during the insertion of the tissue, thereby avoiding interference of other tissue cells with sample detection.
