Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a transvaginal specimen collection auxiliary device for NOSES surgery. Background Art

[0002] In the field of gynecological medicine, transvaginal sampling is a vital routine procedure, widely used in disease diagnosis, treatment monitoring, and preventive screening. The accuracy and safety of this procedure are crucial to ensuring patient health. However, traditional sampling methods have some technical difficulties, especially the problem of air leakage during the sampling process. Air leakage reduces the air pressure in the vagina, which in turn causes the space inside the vagina to become relatively narrow, causing difficulties in the sampling operation. This change in air pressure may not only affect the accuracy of sampling but also cause discomfort to the patient. More importantly, air leakage can provide a way for external bacteria or viruses to enter the vagina, significantly increasing the risk of infection for patients. Utility Model Content

[0033] Please refer to Figure 1 and Figure 2 The present invention provides a NOSES surgical transvaginal specimen collection auxiliary device in a preferred embodiment, comprising an insertion tube 100, a rear cover 200, and an inflation tube 300. The insertion tube 100, the rear cover 200, and the inflation tube 300 can all be made of medical-grade plastics, such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and high-performance polyolefin thermoplastic elastomer (TPE).

[0034] A central channel 110 is formed at the center of the plug-in tube 100 , and a first connecting structure is provided at the rear end of the plug-in tube 100 .

[0035] The front end of the rear connecting cover 200 is connected to the first connecting structure to achieve the connection between the rear connecting cover 200 and the insertion tube 100. The rear end of the rear connecting cover 200 is provided with an operating hole 210 for inserting medical instruments. The peripheral wall of the rear connecting cover 200 is provided with an air inlet pipe 220. The peripheral wall of the outer end of the air inlet pipe 220 is provided with a locking structure 230. The air inlet pipe 220 is provided with a one-way ventilation structure 240. The one-way ventilation structure 240 only allows air to flow from the outer end of the air inlet pipe 220 toward the rear connecting cover 200. That is, the one-way ventilation structure 240 only allows air to be inflated into the rear connecting cover 200 and the insertion tube 100, and cannot prevent air from flowing out of the rear connecting cover 200 and the insertion tube 100. The one-way ventilation structure 240 can be a one-way valve or a one-way diaphragm.

[0036] The inflation tube 300 is used to inject gas. The inflation tube 300 is connected to the outer end of the air inlet pipe 220. The peripheral wall of the end of the inflation tube 300 that connects to the air inlet pipe 220 is provided with a locking structure 310. The locking structure 230 cooperates with the locking structure 310 to axially limit the inflation tube 300, thereby preventing the inflation tube 300 from being withdrawn from the air inlet pipe 220. One end of the inflation tube 300 is connected to an external air supply mechanism, and the other end is connected to the air inlet pipe 220. It is understood that a control valve can be provided on the pipeline of the air supply mechanism to control the inflation flow rate, thereby preventing the inflation speed from causing discomfort to the patient by controlling the flow rate. The air source of the air supply mechanism has been disinfected and sterilized, and will not pose an infection risk to the human body.

[0037] The utility model provides a transvaginal specimen collection auxiliary device for NOSES surgery, which inflates the inserted tube 100 through the inflation tube 300, thereby inflating the inside of the vagina, thereby avoiding the narrowing of the vaginal space due to leakage and affecting the specimen collection; and because the vagina is inflated, the air is discharged from the vagina to the outside, effectively reducing the external air from entering the vagina through the gap, and effectively avoiding the external air from infecting the vagina; the one-way ventilation structure 240 on the air inlet pipe 220 is designed to only allow air to flow from the outer end toward the rear cover 200, preventing air backflow and further reducing the possibility of leakage; the locking structure 230 cooperates with the locking matching structure 310 to ensure stability during the inflation process and prevent leakage due to unstable connection.
