Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a minimally invasive catheter-type synchronous heart assist device includes an actuator 1 and a control module 2. The actuator 1 includes an overall cylindrical lumen enclosed by the cavity wall, and the enclosed lumen is used for placing The middle airbag 11 is provided with a front end airbag 12 and a rear end airbag 13 which are used to act as valves at the front and rear ends of the inner chamber respectively. 1 Controlled by the control module 2 and adapted to the patient's heart beat characteristics to lift blood from the left ventricle to the aorta.

[0037] Ventricular assist device is recognized worldwide as the most effective treatment for various types of end-stage heart failure. From the development of the first generation pneumatic blood pump and the second generation axial flow blood pump in the 1960s to the third generation suspension blood pump today, several generations of scientists have experienced the arduou...

Embodiment 2

[0049] Such as Figure 4 , Figure 5 As shown, the content of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the hoses 14 of the air pump 3 outside the middle airbag 11 and the front end airbag 12 are attached to the cavity wall respectively. In this way, the structure of the present invention can be further reduced to facilitate installation and manufacture, thereby reducing production costs and facilitating popularization and use.

Embodiment 3

[0051] Such as Figure 6 , Figure 7 As shown, the content of this embodiment is basically the same as that of Embodiment 2, and the similarities will not be repeated. The difference is that the front end airbag 12 and the rear end airbag 13 are inflated and inflated, and the inner cavity is interference fit, and the inflated front end The airbag 12 and the rear end airbag 13 are squeezed against the cavity wall to realize the valve action. In this way, the structure of the present invention is simpler and more compact, and the volume of the inner cavity is larger without the concave stopper 17, so that the work of the actuator 1 higher efficiency.

Abstract

The invention relates to the field of cardiac auxiliary circulation, in particular to a minimally invasive catheter type synchronous cardiac auxiliary device and a use method thereof. An execution portion comprises an inner cavity, the inner cavity is enclosed by a cavity wall to form an entirety with a cylindrical shape, and the formed inner cavity enclosed by the cavity wall is used for placingan intermediate gasbag; the front and back ends of the inner cavity are respectively provided with a front end gasbag and a back end gasbag which have valve effects, the front gasbag, the back end gasbag and the intermediate gasbag are respectively and externally connected with an air bump through flexible tubes, and an execution piece is controlled by a control module and is matched with a patient cardiac impluse characteristic to boost blood in the left ventricular to the aorta. According to the minimally invasive catheter type synchronous cardiac auxiliary device, it can be achieved that the blood in the left ventricular can be boosted to the aorta, significant effects are performed on patient recovery after cardiovascular surgery, heart transplantation transition or replacement, myocardial function recovery and permanent treatment of cardiac failure, the cost is low, the device structure is simple and compact, and it is convenient to popularize and promote the device.

Description

Technical field: [0001] The invention relates to the field of cardiac assisting circulation, in particular to a minimally invasive catheter-type synchronous cardiac assisting device and a method for using the same. Background technique: [0002] Heart failure is a disease that seriously threatens human life. About 1 / 5 of heart disease patients in the world will eventually develop heart failure every year. At present, the incidence of heart failure in my country has reached 0.9% and the 5-year mortality rate exceeds 60%. When traditional drug therapy has certain limitations and cannot achieve satisfactory results, and heart transplantation is facing difficulties such as lack of donors and postoperative rejection, researchers have proposed a method of using mechanical devices to help the heart recover and developed a ventricular assist system. device. Since its clinical application in the 1960s, after years of research and clinical application, the application of ventricular ...
