1. An atrioventricular valve clamping device, comprising a support member, an occluding member, and a clamping member, wherein
a direction of a central axis of the occluding member is regarded as a Z-direction, a direction parallel to a width direction of the clamping member and perpendicular to the Z-direction is regarded as a Y-direction, and a direction perpendicular to the Y-direction and the Z-direction is regarded as an X-direction;
the support member has a length in the Z-direction, the occluding member is sleeved on the support member in the Z-direction, and the clamping member is disposed outside the occluding member and configured to be unfolded or folded relative to the occluding member;
the occluding member is resilient and has a three-dimensional shape;
the occluding member comprises two clamping-supporting portions opposite each other in the X-direction, two end portions opposite each other in the Y-direction, and first transition portions each for transition connection between the clamping-supporting portion and the end portion; and
on an X-Y plane, an outer contour of each of the two end portions forms a pointed end extending outward in the Y-direction, wherein the pointed end represents that the end portion is pointed or tend to be pointed, and the end portion at least partially extends beyond the clamping member in the Y-direction.
