Description

Technical Field

[0001] The invention relates to the technical field of cardiac interventional treatment equipment, and in particular to an ultrasound-guided congenital heart disease interventional treatment device. Background Art

[0002] Congenital heart disease (CHD) is a cardiovascular disease related to developmental abnormalities and genetics. It is one of the most common heart diseases. The interventional treatment of CHD is a method of percutaneous puncture of peripheral blood vessels. Under the guidance of X-ray fluoroscopy and the assistance of echocardiography, the catheter is pushed to the corresponding part of the heart lesion for treatment. According to the treatment type of the lesion, it is classified into balloon dilatation (suitable for pulmonary artery stenosis, aortic stenosis, pulmonary valve stenosis, etc.) and transcatheter occlusion (suitable for atrial septal defect, ventricular septal defect, patent ductus arteriosus, etc.). Because the blood vessels inside the human body are uneven and relatively fragile, when performing interventional treatment on human heart disease, under ultrasound guidance, the balloon still needs to be adjusted continuously after entering the body, which will cause certain damage to the human blood vessels. In order to reduce the frequent adjustment of the angle of the balloon after entering the human body, we propose an interventional treatment device for congenital heart disease under ultrasound guidance.
