Description

Technical Field

[0001] The utility model relates to the field of heart valve and blood vessel calcification treatment, in particular to a device for treating heart valve and blood vessel calcification. Background Art

[0002] Heart valve and vascular calcification refers to the process of arteriosclerosis of the heart's mitral valve, tricuspid valve, aortic valve and pulmonary valve and the inner wall of blood vessels, in which calcium salts are deposited on the blood vessel walls, forming hardened plaques that cause the heart to be unable to pump blood normally. Drug therapy, interventional therapy and surgical treatment are usually used. Interventional therapy refers to transporting a balloon to the lesion site under the guidance of a wire, inflating the balloon by perfusing contrast agent and saline into the balloon, and stably fixing it at the lesion site. At the same time, the doctor observes the treatment situation during the perfusion of contrast agent. After the balloon position is fixed, the electrode transmitter set on the catheter emits electrode shock waves to soften the calcified position and achieve the treatment effect. However, the existing electrode transmitter does not have a corresponding fixing structure in the balloon, and due to the tortuosity in the blood vessel, the electrode transmitter is offset in the balloon after the balloon position is fixed, making it impossible to fully and evenly soften both ends of the blood vessel, affecting normal treatment.
