Description

Shockwave balloon for treating vascular calcification TECHNICAL FIELD

[0001] The present application relates to the technical field of shockwave balloon bodies, in particular to a shockwave balloon for treating vascular calcification. BACKGROUND

[0002] Vascular calcification is a common pathological manifestation of atherosclerosis, hypertension, diabetic vasculopathy, vascular injury, chronic kidney disease and aging.

[0003] It mainly manifests as an increase in vascular wall stiffness and a decrease in compliance, which can easily lead to myocardial ischemia, left ventricular hypertrophy and heart failure, and can cause thrombosis and plaque rupture, which is one of the important factors for high morbidity and mortality of cardiovascular and cerebrovascular diseases. It is also an important marker molecule for the occurrence of atherosclerotic cardiovascular events, stroke and peripheral vascular disease. Vascular calcification is generally vascular sclerosis. Calcium deposits appear in the blood vessels, and the ductility of the blood vessels is greatly reduced, which increases the strength of the blood vessels. At this time, the blood vessels become more and more sensitive, and the symptoms of vascular calcification appear. Vascular calcification mainly manifests as an increase in vascular wall stiffness and a decrease in compliance, which is one of the manifestations of atherosclerosis. This is mostly related to age, and as people age, the blood vessel wall may calcify. Vascular wall calcification also occurs secondary to various chronic diseases, such as atherosclerosis and chronic nephritis. The shockwave balloon body is an effective device for treating vascular calcification, which can effectively remove calcified lesions and has the advantages of small trauma and few complications.

[0004] When the shockwave balloon for treating vascular calcification is in use, the expansion diameter of the shockwave balloon body cannot be limited and adjusted according to the lesion size of the patient, so as to prevent the shockwave balloon body from expanding too large and causing damage to the blood vessels of the patient. Meanwhile, the thickness of the shockwave balloon body cannot be improved when the shockwave balloon for treating vascular calcification is in use, which leads to the shockwave balloon body being easily damaged by external factors during use, so that the shockwave balloon body cannot be normally used.

[0016] Compared with the prior art, the shock wave balloon for treating vascular calcification has the following beneficial effects:

[0017] 1. In this invention, when the shockwave balloon body is inflated, the adjusting plate can drive the rubber sliding column to slide inside the circular sliding ring. Since the height-limiting movable ring is made of rubber, when the rubber sliding column slides, it can drive the height-limiting movable ring to contract or expand on the surface of the circular sliding ring. According to the contraction or expansion of the height-limiting movable ring, the height-limiting movable ring can drive the adjusting contraction sliding rod to slide inside the contraction hollow sleeve. By adjusting the sliding of the contraction sliding rod and the contraction hollow sleeve, it can drive the limiting adjusting disc, the fixing block and the height-limiting rod to move, so that the distance between the height-limiting rod and the adjusting plate can be adjusted. The wear-resistant rod is pushed so that it can penetrate the contraction hollow sleeve and extend into the interior of the adjusting contraction sliding rod to fix the adjustment distance between the limiting adjusting disc and the height-limiting rod. This allows the expansion diameter of the height-limiting movable ring to be adjusted in advance, thereby adjusting the expansion range of the shockwave balloon body and preventing the shockwave balloon body from expanding too much and causing damage to the patient's blood vessels.

[0018] 2. This invention utilizes the sliding of a sliding plate and a limiting moving plate. When the shockwave balloon body expands or contracts, the air intake thickening seat can drive the sliding plate to slide on the surface of the limiting moving plate, allowing adjustment of the distance between the air intake thickening seat and the medical catheter. The air intake thickening seat can always be in contact with the inner wall of the shockwave balloon body. When the air intake thickening seat moves using the sliding plate, it can drive the connecting plate, support mounting rod, and bonding plate to move together, allowing the bonding plate and the air intake thickening seat to be in contact with the inner wall of the shockwave balloon body, increasing the thickness of the shockwave balloon body and thus improving its service life.

[0019] 3. When the shockwave balloon body enters the patient's blood vessel, the first lesion detection spade and the second lesion detection spade are used to make it fit against the inner wall of the patient's blood vessel, so that the first lesion detection spade and the second lesion detection spade can detect the location of the lesion in the blood vessel in advance. At the same time, when the shockwave balloon body is treating the lesion in the patient's blood vessel, the treatment effect of the shockwave balloon body is judged based on the thickness of the first lesion detection spade and the second lesion detection spade against the lesion site on the inner wall of the blood vessel.
