Embodiment 1

[0069] Example 1, such as Figure 1-19 Shown by:

[0070] A heart support for a magnetic power heart assist power system, comprising a movable block support 10, the movable block support 10 is used to support the magnetic movable block 1 of the magnetic power heart auxiliary power system, and a firm 11, the stabilizer 11 is used to fix the movable block support 10, so that the relative position between the movable block support 10 and the heart is fixed, and the magnetic movable block 1 and the movable block support 10 are movable The connection of the magnetic block 1 can move toward and away from the heart.

[0071]In the solution of this embodiment, the magnetic block 1 is set on the heart by means of a stent, and the stent can be minimally invasively implanted and fixed outside the heart without causing too much damage, such as the bottom of the heart or the apex of the heart, Or be fixed on other tissues, such as: the aortic root, the relative position of the movable bl...

Embodiment 2

[0099] Example 2, such as Figure 1-19 Shown by:

[0100]A wearable magnetic-powered heart-assisted power system, comprising an external wearable device and an internal body component arranged in a patient, the internal body component includes the heart stent for the magnetic-powered heart-assisted power system described in Embodiment 1, and the internal body component It also includes at least one magnetic block 1 with magnetism, the magnetic block 1 is arranged on the heart, and the external wearable device includes an external magnetic part 2 corresponding to the magnetic block 1, and the external magnetic part The magnetism of 2 is controllable, so that the magnitude and / or direction of the magnetic force formed between the external magnetic part 2 and the magnetic block 1 is controllable, and each of the magnetic block 1 corresponds to at least one external magnetic part 2. The external magnetic component 2 is set on the binding component 22 . In the solution of this em...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a heart stent for a magnetomotive heart auxiliary power system and a system. The heart stent for the magnetomotive heart auxiliary power system comprises a movable block stent, the movable block stent is used for supporting a magnetic movable block of the magnetomotive heart auxiliary power system, and a stabilizing piece is arranged on the movable block stent; the stabilizing piece is used for fixing the loose piece support so that the relative position of the loose piece support and the heart can be fixed, and the magnetic loose piece is movably connected with the loose piece support so that the magnetic loose piece can move in the direction facing and deviating from the heart. According to the scheme, the magnetic movable blocks are arranged on the heart in a support mode, the connection difficulty of the magnetic movable blocks and the heart can be greatly reduced, heart damage caused by connection of the magnetic movable blocks can be greatly reduced, arrangement of more magnetic movable blocks becomes reality, different positions of the heart can be better assisted in a differentiated power mode, and the control precision of the heart auxiliary power is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a heart support and a system for a magnetic power heart auxiliary power system. Background technique [0002] Under normal human conditions, the sinoatrial node in the right atrium of the heart can spontaneously and periodically send out physiological pulse electrical signals, which are transmitted to various parts of the heart through the myocardial nervous system, causing the myocardium to contract and relax periodically, thereby pumping blood to the whole body . [0003] Heart failure is a clinical syndrome characterized by a series of pathophysiological changes caused by abnormal cardiac structure or function leading to impaired ventricular systolic or diastolic ability. When heart failure occurs, the systolic ability of the heart to beat blood decreases, the compliance of the ventricles during diastole decreases, the active filling decreases significantl...
