Disclosed is an atrial appendage clip, including a first clip arm (1) and a second clip arm (2) that are symmetrically arranged； a first cavity (11) and a second cavity (21) are correspondingly provided in the first clip arm (1) and the second clip arm (2) along an 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) is connected with the second clip arm (2) via a first pull wire (13), and the second spring (22) is connected with the first clip arm (1) via a second pull wire (23), so as to form a closed loop structure； and as the first spring (12) and the second spring (22) are stretched or compressed, the first clip arm (1) and the second clip arm (2) are opened or closed therebetween. With the design of arranging the springs (12, 22) in the clip arms (1, 2), the outline dimension of the atrial appendage clip is reduced, and extrusion and abrasion to a peripheral tissue of an atrial appendage are reduced； moreover, with the increase in the thickness of the atrial appendage, the amount of deformation of each of the springs (12, 22) increases, and thus a larger closing force can be provided； by sleeving the atrial appendage with the entire closed loop structure, the atrial appendage can be prevented from escaping from the clip arms after being pressed； and the atrial appendage clip has a skilful design, has a stable and reliable closing force, is convenient to operate, and is safe and effective.
