Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an atrium support with a defibrillation function.
Background
The heart is divided into left and right parts, each part including a ventricle and an atrium, the ventricle being separated from the ventricle by the ventricular septum, the atrium being separated from the atrium by the atrial septum, and valves between the atrium, the ventricle and the artery for preventing the regurgitation of blood. Wherein, the valve between the left atrium and the left ventricle is a mitral valve, the valve between the right atrium and the right ventricle is a tricuspid valve, the valve between the left ventricle and the aorta is an aortic valve, and the valve between the right ventricle and the pulmonary artery is a pulmonary valve.
If the valve fails to close completely or opens insufficiently due to disease or other causes, it will result in blood backflow and inadequate blood flow supply. Such as: for the heart valve diseases, the traditional treatment method is to stop the heart after opening the chest, open the heart to perform surgical repair of the valve or replacement of the artificial valve under the support of low-temperature systemic circulation, and then rebound the heart after the operation is finished, thereby completing the subsequent operation. The surgical trauma, risk of surgical valve replacement, and long-term and expensive rehabilitation therapy after surgery make a large number of patients reluctant to undergo surgery.
With the continuous development of minimally invasive surgical techniques, a prosthetic valve can be introduced into a patient body by using a catheter, namely, a heart valve is placed through a minimally invasive intervention operation, and the chest is not required to be opened in the operation, so that the trauma is small, the postoperative recovery is fast, and a new solution is provided for heart valve stenosis patients who cannot prolong the lives or relieve the pains of the patients by the conventional treatment means at present.
Patients who have undergone heart valve intervention surgery often have atrial fibrillation symptoms easily, but the existing artificial valve does not have the defibrillation function, and life safety of the patients can be endangered if atrial fibrillation cannot be defibrillated in time.
