[0002] Ureteroscope surgery is a minimally invasive surgery used to examine and treat ureter-related problems. This surgery usually enters the ureter through the urethra and bladder, and can be used to examine the inside of the ureter, remove stones or foreign bodies in the ureter, or perform other treatment operations. This surgery is usually performed by urologists or specialists. Before ureteroscope surgery, relevant examinations and preparations will be carried out to ensure the safety and smooth progress of the surgery. Among them, the water sealing cap is generally made of silicone or plastic and is an essential component.

[0003] The anti-reflux water sealing cap is a device used in ureteroscope surgery, aiming to prevent liquid reflux and leakage during the surgery. Through specific designs and materials, the anti-reflux water sealing cap can effectively seal the ureter, prevent liquid backflow, and improve the safety and success rate of the surgery.

[0004] During the current ureteroscope surgery process, frequently inserting and removing the ureteroscope inside the water sealing cap may cause the waterproof structure of the water sealing cap to loosen, thereby increasing the risk of surgical leakage, increasing the infection probability of surgical patients, and increasing the surgical risk. This practice may also cause the irrigation fluid to reflux, affecting the progress of the surgery and being not conducive to long-term use. For this reason, we propose an anti-reflux water sealing cap for ureteroscopes. Content of the Utility Model
