Minimally invasive path of extracorporeal blood pump aorta counterpulsation circulation auxiliary device and implantation method

Abstract

The invention relates to a minimally invasive path of an extracorporeal blood pump aorta counterpulsation circulation auxiliary device and an implantation method. The implantation method of the extracorporeal blood pump aorta counterpulsation minimally invasive path is characterized in that: making a cutting mark in the center of sternum corresponding to a selected part on an aortic valve, drilling a circular hole, implanting and fixing a counterpulsation pump pipeline into an ascending aorta through minimally invasive surgery, and connecting the pipeline to an external counterpulsation pump balloon after exhausting. The method has the advantages that: the circular hole is drilled in the center of the sternum, a hose is implanted into the ascending aorta and fixed through minimally invasive surgery, and the hose is connected to the external counterpulsation pump balloon after exhausting. Through pressure or electrocardio waveforms, a controller achieves synchronous counterpulsation assistance through the diastolic period of the counterpulsation pump, and the purposes of assisting circulation and treating heart failure are achieved. The cure rate of acute heart failure can be greatly improved; after implantation, physical strength permitted, the patient is allowed to take food, urinate, defecate and move out of bed by himself / herself; the ICU residence time is shortened; and long-time assistance is achieved, and no obvious complications exist.

Description

technical field [0001] The invention belongs to the medical and health field, and in particular relates to a minimally invasive path and implantation method of an extracorporeal blood pump aortic counterpulsation circulation assisting 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 ch...

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
