Problems solved by technology
[0003] Among the existing treatment plans, the most commonly used treatment method is to vaporize a part of the plaque by pulse delivery laser, or to excise a part of the plaque in the blood vessel by a rotating blade, and then deliver the drug that inhibits cell proliferation to the inner wall of the blood vessel to correspond The lesion site, so that it can play a long-term role on the inner wall of the blood vessel to prevent the blood vessel from narrowing again; but this method cannot adapt to the situation of various complex blood vessels, especially when there is a curved area in the blood vessel, the existing vasodilation catheter It is easy to cause damage to blood vessels, and there are problems such as the inability to precisely control the positioning and expansion of the vasodilator catheter

The invention provides a blood vessel ultrasonic dilation catheter. The blood vessel ultrasonic dilation catheter comprises a catheter body, an ultrasonic assembly and a plurality of balloon assemblies. The multiple balloon assemblies are arranged at intervals in the length direction of the catheter body. According to the blood vessel ultrasonic dilation catheter, each balloon assembly comprises the multiple balloons arranged on the periphery of the catheter body in the surrounding mode, all the balloons are communicated with the air guide pipes, and the blood vessel ultrasonic dilation catheter can conform to the radian change of the blood vessel, adapt to the more complex blood vessel environment, complete blood vessel detection and plaque breaking tasks and achieve the effect of effectively dilating the blood vessel.
Description
technical field [0001] The present application relates to the technical field of medical devices, and in particular to a blood vessel ultrasonic expansion catheter, a blood vessel expansion device and a blood vessel expansion device. Background technique [0002] With the improvement of social living standards, the number of people suffering from peripheral vascular diseases is also increasing year by year. Peripheral vascular disease includes arterial disease, venous disease, and lymphatic disease; it generally manifests as vasodilation, vascular stenosis, and vascular embolism; such as the most common atherosclerotic disease, it will be clinically manifested as the formation of hardened plaque in the arterial vessel, which will rupture in the A blood clot forms at the rupture, causing the artery to narrow or even close completely, leading to serious consequences such as heart attack or stroke. [0003] Among the existing treatment plans, the most commonly used treatment m...
