Problems solved by technology

IABP also has its obvious disadvantages: ①The hemodynamic support provided is limited, and it depends on the patient's own heart function. When the aortic systolic pressure is lower than 70mmHg, the IABP assisting effect is poor; ②Because the catheter implantation site restricts the patient's activities It cannot be used for a long time; ③When IABP is used for more than 20 days, the risks of vascular complications, infection and bleeding increase greatly

Abstract

The invention relates to a minimally invasive path and implantation method of an extracorporeal blood pump aortic counterpulsation circulatory auxiliary device, which is characterized in that: a circular hole is drilled at the midpoint of the sternum corresponding to a selected part of the aortic valve under the sternal notch and passed through the micro In invasive surgery, the counterpulsation pump pipeline is implanted into the ascending aorta and fixed, and the external blood pump connected to the external counterpulsation pump balloon is implanted in a minimally invasive route of aortic counterpulsation. Beneficial effects: the present invention drills a circular hole at the center of the sternum and implants the flexible tube into the ascending aorta through minimally invasive surgery and fixes it, and connects the external counterpulsation pump balloon after exhaust. Through the pressure or ECG waveform, the controller assists the diastolic synchronous counterpulsation through the counterpulsation pump, which has achieved the purpose of assisting circulation and treating heart failure. It can greatly improve the cure rate of acute heart failure; after implantation, patients can eat, urinate, defecate and leave the bed independently if their physical strength permits; shorten the stay in ICU; assist for a long time without obvious complications.

Description

technical field [0001] The invention belongs to the medical and health field, and in particular relates to a counterpulsation pump pipeline of an extracorporeal blood pump aortic counterpulsation circulation auxiliary device. Background technique [0002] There are a large number of heart failure (HF) patients in the world, and the annual treatment costs a lot of money, which brings a huge economic burden to countries and people all over the world. Modern internal medicine has played an active role in the treatment of heart failure. Conventional treatment methods are still unable to obtain satisfactory results for moderate and severe HF drug treatment; heart transplantation is currently the most effective method for the treatment of end-stage heart failure, but the severity of the donor The shortage limits its development and wide application. Therefore, mechanically assisted circulation has gradually become the main method for the treatment of acute and chronic circulatory...
