Disclosed is an atrial appendage clip, comprising a first clamping arm (1) and a second clamping arm (2) which are symmetrically arranged. A first cavity (11) and a second cavity (21) are correspondingly provided in the first clamping arm (1) and the second clamping arm (2) in the axial direction thereof. A first spring (12) and a second spring (22) are correspondingly provided in the first cavity (11) and the second cavity (21), the first spring (12) being connected to the second clamping arm (2) through a first pull wire (13), and the second spring (22) being connected to the first clamping arm (1) through a second pull wire (23) so as to form a closed ring structure. As the first spring (12) and the second spring (22) are stretched or compressed, the space between the first clamping arm (1) and the second clamping arm (2) is opened or closed. With the design of arranging the springs (12, 22) in the clamping arms (1, 2), the outline dimension of the atrial appendage clip can be reduced so as to reduce the squeezing and abrasion to the peripheral tissue of an atrial appendage. Moreover, with the increase in the thickness of the atrial appendage, the amount of deformation of the springs (12, 22) increases so as to provide a stronger closing force. By holding the atrial appendage with the entire closed ring structure, the atrial appendage can be prevented from escaping from the clamping arms after being pressed. The atrial appendage clip has an ingeniously designed structure, has a stable and reliable closing force, is convenient to operate, and is safe and effective.L'invention concerne une attache d'occlusion d'appendice auriculaire, comprenant un premier bras de serrage (1) et un second bras de serrage (2) qui sont agencés symétriquement.
