Abstract
Description
Technical Field
[0001] This utility model relates to the field of coated guidewire technology, and in particular to a segmented medical coated guidewire. Background Technology
[0002] Guidewires are one of the main tools used in clinical percutaneous catheterization. They guide and support the catheter, helping it enter blood vessels and other cavities, and guiding it smoothly to the lesion site. Guidewires are just as important as the catheter itself in catheter-based therapeutic procedures. The general procedure is as follows: Under medical imaging, a needle is inserted percutaneously. The guidewire passes through the needle and enters the blood vessel or other cavity at the lesion site. The needle is then removed, and the guidewire is inserted into the catheter. The catheter then travels along the guidewire to the lesion site for medication or other treatments.
[0003] Currently, conventional coated guidewires generally have sharp tips, which may damage the patient's blood vessels during use. Additionally, when the guidewire is stored inside the catheter, it may cause infection, thus harming the patient. Furthermore, when the guidewire is inserted into the patient's blood vessel, doctors generally operate based on their experience. During prolonged operation, doctors may experience fatigue, requiring multiple adjustments to the guidewire, which may also cause harm to the patient.
[0004] Therefore, those skilled in the art have provided a segmented medical coated guidewire to solve the problems mentioned in the background art. Utility Model Content

[0014] Furthermore, the second fluorescent part is made of an aluminate material;
[0015] The above technical solution allows for the visualization of the guidewire's position within the blood vessel using X-ray equipment.
[0016] Furthermore, the soft head, the soft part, and the outer surface of the handheld part are all provided with hydrophilic parts;
[0017] The above technical solutions can make the guidewire move more smoothly in blood vessels.
[0018] Furthermore, the hydrophilic part is made of PMMA material;
[0019] Through the above technical solution, PMMA material has excellent hydrophilic properties and is transparent, which facilitates the emission of light from the fluorescent part.
[0020] Furthermore, the radius of the filament located at the flexible portion gradually decreases;
[0021] By employing the above technical solutions, the flexibility of the soft tissue is improved, which facilitates flexible movement through complex vascular structures and reduces damage to blood vessels.
[0022] Furthermore, the filament core is connected to the soft head by injection molding, and the second fluorescent part, antibacterial part and hydrophilic part are all uniformly disposed in layers on the outer wall of the filament core by spraying.
[0023] The above technical solution makes the entire guidewire a single piece, avoiding damage to blood vessels at the welding points.
[0024] Furthermore, the core material is set to NIT material;
[0025] Through the above technical solutions, NITI material has excellent flexibility, which improves the strength of the guidewire.
[0026] Furthermore, the flexible part can be configured to be straight or hook-shaped;
[0027] The above technical solution allows for the selection of different soft part states based on different opening states.
[0028] This utility model has the following beneficial effects:
[0029] 1. The present invention proposes a segmented medical coated guidewire, which avoids the sharp tip of the guidewire from damaging blood vessels by setting a soft head. Furthermore, the first fluorescent part can reduce the fatigue of doctors when using the guidewire and facilitate doctors to accurately locate the position of the guidewire, thereby reducing the discomfort caused to patients by adjusting the guidewire. Different soft parts can be selected according to different opening conditions.
[0030] 2. The segmented medical coated guidewire proposed in this utility model improves the flexibility of the soft part by gradually reducing the radius of the core in the soft part, which is conducive to flexible movement in complex vascular structures and reduces vascular damage. The combination of antibacterial and hydrophilic parts can prevent the guidewire from being infected during storage and improve the lubrication of the guidewire in the blood vessel, thereby reducing patient discomfort during examination.

The soft part 102 can be set to a straight state or a hook-shaped state, and different states of the soft part 102 can be selected according to different opening states.
[0041] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5The coating mechanism 2 includes a wire core 201, with a second fluorescent part 204 at its outer end and an antibacterial part 203 at its outer end. The antibacterial part 203 contains a hydrophilic part 202. This coating mechanism 2 prevents guidewire contamination and improves guidewire lubrication, reducing patient discomfort during examination. The second fluorescent part 204 is made of aluminate material, allowing X-ray imaging to visualize the guidewire's position within the blood vessel. The soft tip 104, the soft part 102, and the handle 101 are all externally provided with hydrophilic parts 202, which further facilitates smoother guidewire movement within the blood vessel. The hydrophilic part 202 is made of PMMA material. The guidewire is made of PMMA material, which has excellent hydrophilic properties and is transparent, facilitating the emission of light from the fluorescent part. The radius of the core 201 gradually decreases at the soft part 102, improving the flexibility of the soft part 102 and allowing it to move flexibly through complex vascular structures, reducing vascular damage. The core 201 is connected to the soft head 104 by injection molding. The second fluorescent part 204, the antibacterial part 203, and the hydrophilic part 202 are all uniformly applied in layers on the outer wall of the core 201 by spraying, making the entire guidewire integral and avoiding damage to the blood vessel at the welding point. The core 201 is made of NITI material, which has excellent flexibility and improves the strength of the guidewire.
[0042] Working principle: The soft tip 104 prevents the guidewire from becoming sharp and damaging blood vessels. The first fluorescent part 103 reduces fatigue for doctors when using the guidewire and facilitates accurate positioning, thus reducing discomfort for patients caused by guidewire adjustments. Different states of the soft part 102 can be selected according to different opening conditions. The gradually decreasing radius of the wire core 201 from the soft part 102 increases its flexibility, allowing for flexible movement through complex vascular structures and reducing vascular damage. The combination of the antibacterial part 203 and the hydrophilic part 202 prevents infection during storage and improves lubrication in blood vessels, thereby reducing patient discomfort during examination.
