[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a medical polypropylene self-lubricating sealed gynecological sampling device, including a sampling tube 1, a piston 2 slidably connected inside the sampling tube 1, a core rod 3 fixedly connected to the side of the piston 2, a handle 4 fixedly connected to the end of the core rod 3 away from the piston 2, a limiting plate 5 slidably connected to the surface of the sampling tube 1, the limiting plate 5 being fixedly connected to the sampling tube 1 through a fixing assembly 13, a plurality of equidistantly distributed adjustment grooves 7 being opened on the outer surface of the sampling tube 1, the fixing assembly 13 including a block 131, a pin 132 slidably connected inside the block 131, the pin 132 being inserted into the corresponding adjustment groove. Inside 7, a pull rod 134 is fixedly connected to the top of the pin 132, and a handle 135 is fixedly connected to the top of the pull rod 134. A spring 133 is sleeved on the surface of the pull rod 134. The two ends of the spring 133 abut against the inner wall of the pin 132 and the block 131 away from the pin 132, respectively. A square plate 9 is fixedly connected to the side of the limiting plate 5. The square plate 9 is located above the handle 135. The outer surface of the sampling tube 1 is provided with scale lines 8. The head of the sampling tube 1 is provided with several sampling holes 6 distributed in a circle. The sampling tube 1 is made of polypropylene. The end of the sampling tube 1 is provided with several annular anti-slip strips 10 distributed at equal intervals.

[0024] In this embodiment, a limiting plate 5 is slidably connected to the surface of the sampling tube 1 and fixed to the sampling tube 1 by a fixing component 13. The position of the limiting plate 5 can be adjusted and fixed as needed, effectively preventing the device from being inserted too deeply due to accidental collisions by staff, reducing the possibility of additional pain, discomfort, and psychological panic for the patient, ensuring the patient's safety and comfort during the sampling process, and improving the overall medical experience. The scale lines 8 set on the outer surface of the sampling tube 1 make it convenient for medical staff to intuitively observe and control the depth of the sampling tube 1 inserted into the patient's body during operation. Combined with the limiting function of the limiting plate 5, it further improves the accuracy of sampling depth control. The sampling tube 1 has several circumferentially distributed sampling holes 6 at its head, increasing the contact area with the sampling site and the channel for sample entry, allowing for more comprehensive sampling during the sampling operation. The sampling tube 1 efficiently collects secretions from the cervix or vagina, ensuring sufficient and representative samples to improve the accuracy of subsequent test results. Made of polypropylene, the tube has excellent biocompatibility, does not cause adverse stimulation or reactions to human tissue, and guarantees safety during sampling in contact with the patient. It also boasts high chemical stability, facilitating disinfection and meeting the hygiene requirements for multiple uses, thus complying with medical device standards. Several equidistantly distributed annular anti-slip strips 10 at the end of the tube 1 increase friction when medical personnel hold it, allowing for a more stable grip, especially during insertion, rotation, or withdrawal, effectively preventing slippage and ensuring smooth and accurate sampling.

[0025] Example 2: As Figure 2 - Figure 3 As shown, a guide rod 12 is fixedly connected to the outer surface of the sampling tube 1. A limiting groove 11 is opened on the inner arc surface of the opening of the limiting plate 5 corresponding to the position of the guide rod 12. The guide rod 12 is locked inside the limiting groove 11.

[0026] In this embodiment, the guide rod 12, which is fixedly connected to the outer surface of the sampling tube 1, cooperates with the limiting groove 11 opened at the inner arc surface of the opening of the limiting plate 5. This guides and limits the sliding of the limiting plate 5, preventing the limiting plate 5 from rotating and affecting the convenience of inserting the pin 132 into the adjustment groove 7, and further improving the working efficiency of fixing the limiting plate 5.

[0027] The working principle of this embodiment is as follows: When using this medical polypropylene self-lubricating sealed gynecological sampling device, medical staff first adjust the position of the limiting plate 5 on the sampling tube 1 according to the patient's specific situation, such as the size of the uterus and the required depth of the sampling site, in order to limit the insertion depth of the sampling tube 1. The specific adjustment process is as follows: Press the square plate 9 and pull the handle 135. The handle 135 drives the pull rod 134 to move upward. The pull rod 134 pulls the pin 132 to overcome the elastic force of the spring 133 and pull it out of the current adjustment groove 7. At this time, the limiting plate 5 can be slid along the surface of the sampling tube 1 to a suitable position. Then, release the handle 135. Under the action of the elastic force, the spring 133 pushes the pin 132 to re-insert into the corresponding adjustment groove 7, thereby fixing the limiting plate 5 in the set position. The stability of the limiting plate 5 during the sliding and fixing process is ensured by the cooperation of the guide rod 12 and the limiting groove 11. Then, the medical staff holds the sampling tube 1 and observes the scale lines on the outer surface of the sampling tube 1. 8. Slowly and steadily insert the sampling tube 1 into the patient's cervix or vagina. When the end of the sampling tube 1 contacts the limiting plate 5, it indicates that the preset insertion depth has been reached, preventing further insertion that could harm the patient. After insertion, the core rod 3 and the piston 2 connected to it can be pulled out by operating the handle 4 (by pre-spraying medical-grade silicone oil on the piston 2 to form a self-lubricating sliding structure, medical staff can easily control the pulling out of the core rod 3). This allows cervical or vaginal secretions to enter the sampling tube 1 through the sampling holes 6 distributed around the head of the sampling tube 1, completing the sample collection. After sampling, the sampling tube 1 is smoothly withdrawn from the patient's body. The collected sample is retained in the sampling tube 1 and can then be sent for subsequent testing and analysis to assist in the diagnosis, prevention, and early treatment of gynecological diseases. Throughout the process, the annular anti-slip strip 10 at the end of the sampling tube 1 helps medical staff to hold the sampling tube 1 stably, ensuring smooth operation.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
