The inner ring (11) is rotatably disposed in the outer ring (12), and a gap (15) where the pull thread (3) can move is reserved between the inner ring (11) and the outer ring (12). The ligating ring (2) is made of an elastic material. One end of the pull thread (3) is fixed on the ring-shaped forceps (1), and the other end sequentially penetrates the thread hole (14) on the outer ring (12), the gap (15) between the outer ring (12) and the inner ring (11), and the thread hole (14) on the inner ring (11) and is then connected to the ligating ring (2). The ligation device has a simple structure and is easy to use. Users can operate the ligation device conveniently even when wearing gloves.
