Embodiment Construction

[0040]Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding and should be considered as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

[0041] To solve at least one of the problems in the background art, one aspect of the present invention provides a heart valve positioning device. In practice, the existing artificial heart valve is directly connected to the inner wall of the aorta, and the anchoring strength of this connection method is difficult to achieve as expected, which is likely to cause intraoperative ...

Abstract

The invention discloses a heart valve positioning device which comprises anchoring units, and the number of the anchoring units is not smaller than the number of valves at a target installation position. The plurality of anchoring units are distributed along the circumference and are connected with one another through axially extending connecting parts to form a closed hollow thin-wall structure; each anchoring unit comprises an upper component and a lower component, the two ends of the upper component and the two ends of the lower component are fixedly connected with the connecting parts respectively, and two connecting points on the same side of each connecting part are distributed at intervals; the upper component and the lower component are arranged at intervals in the axis direction of the hollow thin-wall structure, at least one first interval is formed between the upper component and the lower component, and the first interval is used for clamping a heart native valve. The clamping force of the native valve between the upper component and the lower component can be adjusted by controlling the distance of the gap between the upper component and the lower component; the clamping mode of the original valve leaflet is simplified, and the design complexity and the machining difficulty are reduced.

Description

technical field [0001] The invention relates to medical equipment, in particular to a heart valve positioning device, and belongs to the technical field of medical equipment. Background technique [0002] Aortic valve stenosis and aortic regurgitation are common clinical degenerative diseases of human aortic valve. In the existing treatment plan, the artificial device relies on the radial support force to abut against the calcified part of the human aortic valve, and then anchor at the native valve leaflet to replace the native valve and restore normal blood flow at the aortic valve. However, the anchoring strength of the existing prosthetic valves is difficult to achieve expectations, especially for mildly calcified aortic stenosis and simple aortic regurgitation, the aortic valve has few or no calcifications, and the valve leaflets are relatively soft and cannot be used for calcification. The prosthetic aortic valve provides adequate support. In addition, for the aortic ...
