[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] See also Figures 1-2 As shown, in this embodiment, a fistula urinary catheter is provided, including a tube body 1, a liquid outlet 2 is provided at the tail end of the tube body 1, a water injection hard valve 3 is connected to the tube body 1 near the liquid outlet 2, and a urinary catheter head 4 is connected to the front opening of the tube body 1. The outer surface of the urinary catheter head 4 is arc-shaped, so that the urinary catheter head 4 and the tube body 1 are easier to enter the urinary catheter.

[0023] The front end of the tube body 1 is also provided with a urine inlet 11, which is connected to the liquid outlet 2 through a through hole of the tube body 1. The tube body 1 is provided with a developing line 12 extending axially from the front end to the rear end. The front end of the tube body 1 is provided with a balloon 5, and the outer surface of the balloon 5 is flush with the outer surface of the tube body 1. The flush-designed balloon 5 and the tube body 1 are in the same plane. This design not only helps to improve the stability of the catheter and the comfort of the patient, but also ensures the smoothness of the instrument channel and reduces the difficulty and risk of operation.

[0024] Furthermore, since the flush-designed balloon 5 does not occupy the space of the instrument channel, the doctor does not need to select a larger instrument to accommodate the balloon 5, which not only simplifies the surgical procedure but also reduces the difficulty of operation and the pain of the patient.

[0025] Furthermore, a smooth instrument channel can reduce the doctor's operating time during surgery, thereby improving surgical efficiency. Avoiding the selection of larger-sized instruments can also help reduce surgical risks, ensure patient safety, and help improve treatment outcomes and patient satisfaction. Appropriate-sized instruments can reduce the occurrence of complications and increase the patient's recovery speed.

[0026] In this embodiment, a plurality of reinforcing ribs 51 are arranged along the axis on the inner wall of the balloon 5 . The balloon 5 expands after being filled with water, and the radial strength of the balloon 5 can be improved by the provided reinforcing ribs 51 .

[0027] See also Figures 3-4 As shown, a groove 14 is provided at the connection between the outer wall of the tube body 1 and the balloon 5, and the balloon 5 is accommodated in the groove 14, so that the outer surface of the balloon 5 and the tube body 1 are in the same plane, and there is a gap between the balloon 5 and the groove 14. The tube body 1 is also provided with a liquid inlet hole 13, one end of the liquid inlet hole 13 is connected to the water injection hard valve 3, and the other end of the liquid inlet hole 13 is located on the inner side of the balloon 5. Liquid is injected from the water injection hard valve 3 and enters the gap between the groove 14 and the balloon 5 through the liquid inlet hole 13, so that the balloon 5 expands.

[0028] In this embodiment, the surface of the balloon 5 is coated with an antibacterial coating, which can effectively inhibit the growth of bacteria and conversely reduce the risk of urinary tract infection.

[0029] Specifically, the antibacterial coating includes an antibacterial agent, which can destroy the cell wall of bacteria or inhibit their metabolic activities, thereby achieving the antibacterial purpose.

[0030] Furthermore, the balloon coating can also be a hydrophilic coating, which, in addition to its antibacterial function, can also play a lubricating role, reduce the friction between the balloon 5 and the bladder wall, further ensure the smoothness of the instrument channel, and help reduce the patient's discomfort and improve the comfort of the catheter.

[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
