A non-slip balloon dilation catheter was designed, comprising a Y-shaped connector, a stress diffusion tube, a catheter, a balloon, an inner tube, and a contrast ring. The contrast ring provides precise positioning, while the concave waist and non-slip surface of the balloon prevent slippage. The guide end and tapered end of the inner tube provide auxiliary guidance, ensuring that the balloon accurately enters the dilation site.
It reduces the risk of balloon slippage, improves the accuracy and efficiency of treatment, and reduces treatment costs and surgical risks for patients.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to an anti-slip balloon dilation catheter. Background Technology
[0002] Pulmonary valve stenosis, aortic valve stenosis, peripheral vascular stenosis or occlusion, and intracranial arterial stenosis are among the most common vascular diseases that can occur throughout the human body.
[0003] Pulmonary valve stenosis obstructs blood flow from the right ventricle to the pulmonary artery, leading to increased right ventricular pressure, compensatory enlargement of the right heart, thickening of the ventricular wall, and ultimately, right ventricular failure. Moderate stenosis in older individuals may cause fatigue or shortness of breath after activity; severe stenosis may cause dyspnea and weakness after activity, sudden syncope, or sudden death. Aortic valve stenosis can also lead to heart failure, insufficient blood supply to the brain, and endocarditis. Untreated peripheral vascular disease can cause severe pain, stroke-induced hemiplegia, and necrosis of the extremities. Mild intracranial arterial stenosis can cause insufficient blood supply to the brain, while severe stenosis can lead to acute cerebral infarction.
[0004] These diseases all require balloon dilation catheters for treatment. However, in actual clinical use, existing balloon dilation catheters are prone to slipping out of the dilation site, making it impossible to dilate properly. This delays treatment time, increases surgical risks, and increases treatment costs for patients. Therefore, there is an urgent need for an anti-slip balloon dilation catheter to solve the above problems. Utility Model Content
[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide an anti-slip balloon dilation catheter.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0007] An anti-slip balloon dilation catheter includes a Y-shaped connector, a stress diffusion tube connected to the Y-shaped connector, a catheter connected to the stress diffusion tube, a balloon connected to the catheter, a concave waist at the center of the balloon, anti-slip surfaces on the upper and lower sides of the concave waist, an expansion surface on the outer side of the anti-slip surfaces, an inner tube installed inside the balloon, a plurality of radiopaque rings installed in the inner tube, the radiopaque rings being located inside the balloon, and the inner tube being disposed within the catheter and the stress diffusion tube.
[0008] Furthermore, the balloon has tapered ends on both the upper and lower sides. This structural design facilitates the movement of the balloon within the blood vessel.
[0009] Furthermore, the bottom of the inner tube extends from the bottom of the balloon, and the extended portion has a tapered guide end. This structural design serves a guiding function.
[0010] Furthermore, the number of developing rings is two, and they are fixedly installed on the inner tube. This structural design facilitates fixed installation and use.
[0011] Furthermore, the balloon has different outer diameters and lengths, the catheter has different outer diameters and lengths, and the inner tube has different inner diameters. This structural design allows for a wide range of choices, enabling the selection of the required specifications from multiple perspectives.
[0012] The beneficial effects of this utility model are as follows: By setting up a balloon, a concave waist, an anti-slip surface, and an expansion surface, this utility model can reduce the risk of the balloon slipping out of the area that needs to be expanded during clinical use, thereby achieving the goal of treating diseases in the shortest possible time, reducing the treatment cost for patients who have to undergo surgery again due to unsuccessful surgery, and reducing the potential risks that may arise during surgical treatment.
