Disclosed is an atrial appendage clip delivery system, which includes a handle shell (3), a push rod (4), a connection pipe (5) and a support base (6)； a passage is provided in the handle shell (3) along a length direction； one end of the push rod (4) is slidably disposed in the passage； the support base (6) is provided with a mounting window (61) for mounting an atrial appendage clip； the atrial appendage clip includes a first clip arm (1) and a second clip arm (2) capable of opening in parallel or closing in parallel； the handle shell (3), the connection pipe (5) and the support base (6) are sequentially connected and communicate； the first clip arm (1) or the second clip arm (2) is fixedly connected with an upper side or a lower side of the mounting window (61) by a fixed pull wire (8)； the fixed pull wire (8) sequentially passes through the support base (6) and the connection pipe (5), and then is fixedly connected with the handle shell (3)； the second clip arm (2) or the first clip arm (1) is movably connected with the lower side or the upper side of the mounting window (61) by a movable pull wire (9)； and the movable pull wire (9) sequentially passes through the support base (6) and the connection pipe (5), and then is connected with an end portion of the push rod (4). With the atrial appendage clip delivery system, the atrial appendage clip can be conveniently and reliably placed from an outside of a heart to a root of a left atrial appendage to close the left atrial appendage in a thoracotomy or minimally invasive surgery.
