The invention provides a ligation clip. The ligation clip comprises a first arc-shaped clip arm and a second arc-shaped clip arm. The free end of the first arc-shaped clip arm is provided with a clamping hook. The free end of the second arc-shaped clip arm is provided with a clamping head. The first arc-shaped clip arm is provided with a cylindrical clamping hook clamping body. The second arc-shaped clip arm is provided with two clamping head clamping bodies which are arranged opposite to each other. A clamping body connection circular arc is arranged at the joint of the first arc-shaped clip arm and the second arc-shaped clip arm. The distance between the clamping hook clamping body and the midpoint of the outermost side of the clamping body connection circular arc is the same as the distance between each clamping head clamping body and the midpoint of the outermost side of the clamping body connection circular arc. The diameter of the cylinder of the clamping hook clamping body is equal to the diameter of a cylindrical surface of each clamping head clamping body. The ligation clip can be used for different operation environments; no matter what size of the ligation clip in need is, the ligation clip can be well matched with an instrument as long as the regular design of the ligation clip is followed, optimal clamping force can be obtained, and the ligation clip cannot be damaged in the closing process.
