[0006] To achieve the above objectives, the present invention adopts the following technical solution: a user-friendly sterile urinary guide wire guiding device, comprising a circular tube, a conical tube a fixedly connected to the top of the circular tube, the inner wall of the conical tube a coated with a medical antibacterial coating, a primary limiting hole at the bottom of the conical tube a, a conical tube b fixedly connected to the bottom of the circular tube, an antibacterial coating layer fixedly connected to the exterior of the circular tube, the conical tube a, and the conical tube b, and a secondary limiting hole at the bottom of the conical tube b, wherein the diameter of the primary limiting hole is slightly larger than the diameter of the secondary limiting hole;

[0007] As a further description of the above technical solution: the circular tube has a filament that runs through and slides through the conical tube a and conical tube b, and an adaptive antibacterial and dustproof filler is fixedly connected inside the filament, and adaptive filament heads are fixedly connected to both ends inside the adaptive antibacterial and dustproof filler.

[0008] As a further description of the above technical solution: the adaptive antibacterial and dustproof filler is internally fixedly connected with a filament core, and two partitions are fixedly connected to both ends of the filament core in the horizontal direction, and the other end of the two partitions is fixedly connected to the adaptive filament head;

[0009] As a further description of the above technical solution: both the outer surfaces of the circular tube and the conical tube b are fixedly connected with a skin-friendly coating layer, the primary limiting hole has a smooth chamfered edge, and the inner wall of the conical tube b is coated with a medical antibacterial coating.

[0010] As a further description of the above technical solution: a protective layer is fixedly connected to the outer wall of the filament, the protective layer can adapt to deformation, and the filament can pass through the primary limiting hole and the secondary limiting hole;

[0011] As a further description of the above technical solution: the top edge of the conical tube a is smoothly chamfered, the primary limiting hole is inside the circular tube and does not contact it, and the main bodies of the circular tube, conical tube a, and conical tube b are all medical disposable environmentally friendly biodegradable materials;

[0012] As a further description of the above technical solution: the bottom diameter of the circular tube is the same as the top diameter of the tapered tube b, the bottom edge of the secondary limiting hole opened at the bottom of the tapered tube b is smoothly chamfered, and the top diameter of the tapered tube a is larger than the top diameter of the circular tube.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the irregularly shaped urinary guidewire is roughly shaped by the upper and lower limiting holes. With the adaptive wire tip at the front end of the guidewire, the entire guidewire adapts to the required shape during operation, thereby achieving quick, convenient and practical operation, saving a lot of preparation time and improving surgical efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a user-friendly sterile urinary guidewire guiding device, comprising a circular tube 1 for connecting upper and lower components and protecting the internal structure. A conical tube a2 is fixedly connected to the top of the circular tube 1 for primary shaping. The inner wall of the conical tube a2 is coated with a medical antibacterial coating. The medical antibacterial coating can ensure that the inside of the device remains sterile, but it has a time limit. This utility model is a disposable medical device, so there is no need to consider the time limit of the medical antibacterial coating. The bottom of the conical tube a2 has a primary limiting hole 12 for shaping and limiting. The bottom of the circular tube 1 is fixedly connected to a conical tube b4 for secondary limiting. The outer surfaces of the circular tube 1, the conical tube a2, and the conical tube b4 are all covered with an antibacterial coating 10 to keep the inside of the device sterile. The bottom of the conical tube b4 has a secondary limiting hole 13 for secondary limiting and shaping. The diameter of the primary limiting hole 12 is slightly larger than the diameter of the secondary limiting hole 13 to ensure that the wire 3 can pass through the two limiting holes in sequence.

[0025] Reference Figures 2 to 5 The inside of the circular tube 1 is slidably connected to a filament 3, which is used to clear the urethra during medical treatment and guide the subsequent catheter entry. The inside of the filament 3 is fixedly connected to an adaptive antibacterial and dustproof filler 6 to ensure that the filament 3 is sterile when it is inserted into the body. The two ends of the adaptive antibacterial and dustproof filler 6 are fixedly connected to an adaptive filament tip 5 for advancing along the urethra.

[0026] Reference Figures 1 to 5 The adaptive antibacterial and dustproof filling 6 has a fixed internal connection to the core 8 and the main body of the silk body 3. Two partitions 7 are fixedly connected to both ends of the core 8 in the horizontal direction to separate the adaptive silk tip 5 and the core 8. The other end of each partition 7 is fixedly connected to the adaptive silk tip 5 for insertion into the urethra. A skin-friendly coating 11 is fixedly connected to the outer surfaces of both the circular tube 1 and the conical tube b4 to ensure patient comfort during use. The primary positioning hole 12 has smooth chamfered edges to prevent scratching the patient and user. The inner wall of the conical tube b4 is coated with a medical antibacterial coating to ensure a sterile environment inside the device. The top of the conical tube a2... The edges are smoothly chamfered. The primary limiting hole 12 is inside the circular tube 1 and does not contact it. The main bodies of the circular tube 1, the conical tube a2, and the conical tube b4 are all made of medical disposable environmentally friendly biodegradable materials. This device is a disposable medical device and needs to be disposed of after use. The environmentally friendly materials ensure that it does not pollute the environment. The bottom diameter of the circular tube 1 is the same as the top diameter of the conical tube b4 to ensure airtightness when fixed. The bottom edge of the secondary limiting hole 13 opened at the bottom of the conical tube b4 is smoothly chamfered to prevent scratching patients and medical staff during use. The top diameter of the conical tube a2 is larger than the top diameter of the circular tube 1 to facilitate the entry of the filament 3 into the device.

[0027] Working principle: With the cooperation of the primary limiting hole 12 in the conical tube a2 and the secondary limiting hole 13 in the conical tube b4, the originally irregularly shaped silk body 3 is molded into a fixed shape. The main body is easily inserted into the patient's body through the skin-friendly layer 11 attached to the outer surface of the circular tube 1, the conical tube a2, and the conical tube b4. The adaptive silk head 5 inside is protected by the protective layer 9, and the silk core 8 behind it is shaped according to the internal structure of the urethra. The adaptive silk head 5 and the silk core 8 are separated by a partition 7 to prevent the components with different functions from affecting each other. There is also a protective layer 9 inside the silk body 3 to inhibit bacterial growth.

[0028] The round tube 1, conical tube a2, and conical tube b4 all have an antibacterial coating 10 inside, which can inhibit and adsorb internal bacteria and impurities, ensuring a sterile environment inside the instruments and preventing external impurities from entering the patient's body when the instruments are inserted during surgery.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
