Problems solved by technology

[0004] The technical problem to be solved in the present invention is to try to develop a new type of bionic artificial ventricle, install it in the enlarged ventricular cavity of patients with end-stage heart failure, and remove the papillary muscle, replace the mitral valve, and make the artificial ventricle and atrioventricular valve, aorta After the basal part is properly anastomosed, no motor, no blood pump, no artificial blood vessel, no hydraulic / pneumatic device is used, and the magnetic power is used to make the elastic "finger" of the ventricular balloon adhere to the wall under the guidance of different magnetic field directions and the adjustment of the monitoring system. Generate clutch movement to complete the contraction and contraction functions of the bionic heart

Embodiment Construction

[0008] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] First construct the basic framework of the artificial ventricle 7 . An elastic material is selected to weave into a net and molded into a basic stent 11 of the artificial ventricle. Two openings are left at the upper end, which are continuous with the aorta 1 and the artificial atrioventricular valve 3 respectively. A plurality of elastic fingers 5 that can be combined are attached to the side of the mesh support 11. The direction of the fingers is basically horizontal. The opposite sides of the combined fingers are respectively attached to the magnetic block 8 with high magnetic flux on the right side and the left side can alternately change the current direction. on coil 4. Among them, the right magnetic block 8 is fixed to the fingertip, and there are many tunnel-like finger cots 9 inside, which can accept the back and forth passage...

Abstract

A bionic heart able to the permanently implanted in the heart chamber of the patient of heart failure features that the motor, blood pump, artificial blood vessel and hydraulic / pneumatic unit are unnecessary, but the magnetic power is necessary. Under the pilot of different magnetic field directions and the regulation of monitor system, the elastic í‹fingersíŒ close to the wall of the ball as ventricle can generate the í‹separation-gatheringíŒ movement to simulate the diastole-systole function of heart.

Description

technical field [0001] The invention relates to the field of medical instruments. Background technique [0002] With the deepening of people's understanding of human physiology and the development of energy and material technology, total artificial heart (TAH) and long-term ventricular assist circulation (VADS) have also been further developed, specifically manifested in the development of external pneumatic pumps to super-compressed electric pumps , Assisted circulation can develop towards carrying a total artificial heart. However, the current permanent artificial heart and ventricular assist devices basically include four components: blood pump, driving device, monitoring system and energy supply. The main problems are: large size, cumbersome procedures, expensive price, and unstable function. , Not in line with physiology. [0003] In a philosophical sense, simplicity is the highest state of things. Due to the laws of nature, the structure of any living body is relati...
