Problems solved by technology
[0004] However, in the related art, the overall diameter of the clamp is relatively large, and the inner diameter of the human blood vessel is limited, which makes it difficult for the clamp to enter the heart through the blood vessel; It cannot be adjusted effectively, and it is difficult to disengage from the chord tendon, which may damage the chord tendon, and may even cause the failure of the operation; Block each other when making adjustments, resulting in poor adjustments

The present invention discloses a valve clamping device and a valve clamping system. The valve clamping device comprises a first clamping arm assembly, a first transmission part and a second clamping arm assembly, wherein the first clamping arm assembly comprises a first clamping arm, the second clamping arm assembly comprises a second clamping arm, one end of the first transmission part is in transmission connection with the first clamping arm assembly, and the other end of the first transmission part is in transmission connection with the second clamping arm assembly. The first transmission part penetrates through the second clamping arm assembly, the first clamping arm assembly has a separation position and a combination position under the transmission action of the first transmission part, and when the first clamping arm assembly is located at the separation position, the first clamping arm can be located at the first folding position, and the second clamping arm can be located at the second folding position. By means of the arrangement, the distance between the first clamping arm assembly and the second clamping arm assembly can be increased, mutual obstruction is prevented, the first clamping arm and the second clamping arm can be located at the first folding position and the second folding position respectively, and therefore the overall radial size of the valve clamping device can be reduced, and implantation of the valve clamping device can be facilitated.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a valve clipping device and a valve clipping system. Background technique [0002] The mitral valve consists of a pair of leaflets, called the anterior leaflet and the posterior leaflet, attached to the periphery of the left atrium and connected to the papillary muscle by the chordae. A normal, healthy mitral valve controls the flow of blood from the left atrium to the left ventricle while preventing the flow of blood from the left ventricle back to the left atrium. [0003] Mitral regurgitation (MR) is a condition caused by poor anastomosis of the anterior and posterior leaflets of the mitral valve due to organic or functional changes in the leaflets of the mitral valve or its related structures, and blood flows back from the left ventricle to the left atrium. A series of pathophysiological changes. The valve clamp developed based on the principle of surgical valve...
