[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 6 This utility model provides a technical solution: a urinary tract stent, which is mainly used in the scenario of guiding urine in patients with urinary tract stricture.

[0029] Example 1:

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 In order to make the device easier to remove during use, a delivery pipe 1 and a pull ring 2 are provided;

[0031] One end of the delivery tube 1 is equipped with a pull ring 2. The outer surface of the delivery tube 1 is marked with graduation lines 6. An imaging line 7 is fixedly connected inside the delivery tube 1. One end of the delivery tube 1 is fixedly connected with a limiting tube 8. One end of the limiting tube 8 is fixedly connected with a traction line 9. A hook 10 is fixedly connected to one side of the pull ring 2. The inner wall of the hook 10 engages with the outer surface of the traction line 9. The outer surface of the delivery tube 1 is engraved with clear graduation lines 6, which helps medical staff to accurately determine the length of the device in the body and ensure precise placement. In addition, the imaging line 7 is fixed inside the delivery tube 1. This line is clearly visible under X-ray, which further facilitates the monitoring and confirmation of the device position by medical staff. In order to ensure the stability of the stent, one end of the delivery tube 1 is fixedly connected with a limiting tube 8, and one end of the limiting tube 8 is connected to the traction line 9. After the device is inserted into the patient's body, the traction line 9 is left at the patient's urethral opening for easy removal of the device. The pull ring 2 is also equipped with a hook 10 on one side. The hook 10 allows medical staff to easily assemble and disassemble the pull ring 2 as needed, thereby improving the convenience of the device.

[0032] Example 2:

[0033] Please see Figure 1 and Figure 4 In order for the device to support the patient's urethra during use, a spring 3 is provided;

[0034] The delivery tube 1 is equipped with a support spring 3 inside. One end of the spring 3 is fixedly connected to a fixing tube 11. The outer surface of the fixing tube 11 is threadedly connected to the inner wall of the limiting tube 8. The spring 3 is set inside the delivery tube 1 and has good elasticity and resilience. It can provide effective support after the device is inserted into the urethra. One end of the spring 3 is fixedly connected to the fixing tube 11, and the outer surface of the fixing tube 11 is threadedly connected to the inner wall of the limiting tube 8. This design can ensure the stable installation of the spring 3, effectively prevent problems such as urethral collapse or stenosis, and ensure the smooth discharge of urine.

[0035] Example 3:

[0036] Please see Figure 1 and Figure 5 In order to make it easier to insert the device into the patient's body during use and to prevent it from slipping, a curved tube 4 and a conical tube 5 are provided;

[0037] One end of the delivery pipe 1 is fixedly connected to a bend 4, and one end of the bend 4 is provided with a tapered pipe 5. A fastening pipe 12 is fixedly connected to one end of the bend 4. A ureteral orifice 13 is opened on the outer surface of the bend 4. A threaded hole 14 is opened at the top of the tapered pipe 5, and a guide head 15 is threadedly connected to the top of the threaded hole 14. An assembly pipe 16 is fixedly connected to the bottom of the tapered pipe 5. The outer surface of the assembly pipe 16 is threadedly connected to the inner wall of the fastening pipe 12. The top of the tapered pipe 5 has a threaded hole 14, which is threadedly connected to the guide head 15. The guide head 15 does not... It not only serves to guide the insertion direction but also reduces friction between the device and the patient's urethra, facilitating device insertion. The bottom of the conical tube 5 is fixedly connected to the assembly tube 16, and the outer surface of the assembly tube 16 is threaded to the inner wall of the fastening tube 12. This design makes the connection between the curved tube 4 and the conical tube 5 more secure, effectively preventing the conical tube 5 from slipping out of the body. In addition, a ureteral orifice 13 is opened on the outer surface of the curved tube 4, which helps urine to drain smoothly after the device is inserted, reducing the risk of urine accumulation and increasing the device's protective properties.

[0038] In this invention, the working steps of the device are as follows:

[0039] First, the device is inserted into the appropriate position in the patient's urethra through the tapered tube 5. The position of the stent is observed using the scale line 6 and the imaging line 7. Next, the spring 3 supports the urethra to ensure smooth flow of urine. Then, the urine enters the curved tube 4 and flows through the delivery tube 1. When it is necessary to remove the device, the medical staff hangs the pull ring 2 on the traction line 9 through the hook 10. The traction line 9 provides additional traction force to remove the device from the urethra.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
