The invention relates to an in-vitro ventricular auxiliary device, belongs to the field of artificial heart, and aims to solve the problem that an inlet and an outlet of a centrifugal pump are respectively connected with a left ventricle and an aorta in a thoracotomy mode due to large size of the centrifugal pump. Through the extracardiac bypass operation mode, the long-term auxiliary function of the left ventricle can be achieved. However, according to the operation mode, a large amount of preoperative evaluation work needs to be carried out when patients suffering from acute heart failure, and rescue measures cannot be implemented in time possibly. One catheter is inserted into the aortic arch through the subclavian arteria and enters the left ventricle through the aortic valve, meanwhile, the other catheter is directly inserted into the femoral artery, and the other ends of the two catheters are connected to an inlet and an outlet of the centrifugal blood pump respectively, so that a complete circulation l
