As a preferred technical solution of the present application, the flexible film 115 has elasticity, and when the inner side edge of the magnetic loose piece 111 is flush with the inner side edge of the notch 114, the flexible film 115 is in a natural stretching state. The flexible membrane 115 prevents the magnetic loose piece 111 from falling off from the heart, and when the magnetic loose piece 111 moves towards the heart direction and provides pressing power assistance to the heart area, when the magnetic loose piece is pressed in place, the flexible membrane 115 enables the magnetic loose piece 111 to reset through elasticity of the flexible membrane, namely, in the embodiment, the resetting of the magnetic loose piece 111 is provided by the flexible membrane 115, and the external component is not required to provide a corresponding magnetic field to reset the magnetic loose piece 111.

As a preferred solution, the flexible membrane 115 is disposed outside the heart stent 112 and the magnetic loose piece 111. In this way, firstly, the manufacturing is convenient, the problems of the flexible membrane 115 contacting with the heart can be avoided, and the flexible membrane 115 has a larger connecting area with the magnetic loose piece 111 and the heart support 112, so that the reliability of the connection is ensured.

As a preferred technical solution of the present application, an elastic membrane 116 having elasticity is disposed on the notch 114, the magnetic loose piece 111 is disposed on the elastic membrane 116, the magnetic loose piece 111 has an initial position, when the magnetic loose piece 111 is located at the initial position, one side of the magnetic loose piece 111 facing the heart contacts with a heart side wall in a diastolic state, and the elastic membrane 116 is in a natural stretching state. In the embodiment, the elastic membrane 116 is disposed on the notch 114, and then the magnetic movable block 111 is disposed on the elastic membrane 116, when the external magnetic component applies a pushing force to the magnetic movable block 111, the magnetic movable block 111 overcomes the elastic force of the elastic membrane 116 to perform pressing power assistance on the heart, and when the magnetic field of the external magnetic component is eliminated, the magnetic movable block 111 returns to the initial position under the elastic force of the elastic membrane 116, as described above, such a manner greatly reduces the control requirement and the control difficulty for the external component.

As a preferred solution, the elastic membrane 116 closes the notch 114. On one hand, the uniform magnetic loose piece 111 is stressed in the circumferential direction, and on the other hand, the shell forms a closed space, which is beneficial to protecting the heart.

As a preferred solution, the magnetic loose piece 111 is arranged on the side of the elastic membrane 116 facing away from the heart.

Example seven: as shown with reference to figure 10 of the drawings,

the difference between this embodiment and the first embodiment is: the magnetic loose piece 111 comprises a pressing part 117 and a magnetic part with magnetism, and the magnetic part is arranged on the side of the pressing part 117, which faces away from the heart. In this way, the pressing part 117 is made of a conventional material with good biocompatibility, the structure of the pressing part is matched with the shape of the heart, the magnetic loose piece 111 is provided with the pressing part 117 and the magnetic part, the magnetic part is made of a magnetic material, and when the magnetic part is manufactured, compared with a way that the whole magnetic loose piece 111 is a magnet, the way of the scheme can adopt a normal magnet production way to produce the magnetic part on one hand, does not need to consider the special shape of the heart to make adjustment, and does not need to consider the contact with the heart (the magnet still needs to be wrapped by a material with good biocompatibility) to put higher requirements on the other hand, thereby greatly reducing the manufacturing difficulty of the magnet 120 in the scheme; on the other hand, the shape of the magnet with a conventional structure can be adopted, and the formed magnetic field is more regular, so that the manufacturing difficulty of the magnet 120 and the difficulty of controlling the external magnetic field are greatly reduced.

As a preferred solution of the present application, the magnetic portion includes a mounting seat 119 and a magnet 120 disposed on the mounting seat 119, and the mounting seat 119 is disposed on a side of the pressing portion 117 facing away from the heart. In this way, the connection between the magnetic portion and the pressing portion 117 is further facilitated, and the requirement for manufacturing the magnet 120 is reduced.

As a preferred embodiment of the present invention, the magnet 120 is a permanent magnet or a halbach array magnet. The permanent magnet (or a novel magnetic material) is adopted, so that the service life of the system can be greatly prolonged, and the replacement frequency of the magnetic loose piece 111 in the body is reduced; when the halbach array magnet is adopted, compared with the traditional magnet, when a magnetic field with the same strength is formed, the magnet material can be greatly reduced, the weight of the magnetic loose piece 111 of the patient can be greatly reduced, the stability of the position of the heart of the patient is improved, and the displacement risk of the magnetic loose piece 111 caused by the impact of the daily action of the patient is reduced.

As the preferential technical solution of this application, be provided with step 121 on the lateral wall of breach 114, one side that breach 114 is close to the heart is the great macrostoma of size, keeps away from the heart one side be the minor mouth of size, press the portion 117 edge with the cooperation of major mouth lateral wall slidable, magnetism portion is located in the minitoma, perhaps, magnetism portion by the minor mouth stretches out to outside the heart support 112. In such a way, the risk that the magnetic loose piece 111 falls off from the heart support 112 is avoided, and the step 121-shaped notch 114 can also form a good guiding function, so that the magnetic loose piece 111 is ensured to move towards the heart and away from the heart, and when the magnetic part extends out of the heart support 112 from the small opening, the distance between the magnetic loose piece and an external magnet is shortened, the requirement on the external magnetic field intensity is further reduced, particularly, the magnetic field interference formed by other external magnets is reduced, and the control precision of the magnetic loose piece 111 is further improved.

As a preferred solution of the present application, the mounting seat 119 is provided with a clamping groove 122 for clamping the magnet 120.
