Embolism spring ring

The utility model belongs to the technical field of medical instruments, and discloses an embolism spring ring which comprises a pushing pipe, a first clamping jaw, a pushing piece and a spring ring body. And the pushing piece is connected in the pushing pipe in a sliding manner. The first clamping jaw is arranged on the pushing pipe and contracts in a natural state, and the pushing piece selectively abuts against the first clamping jaw so that the first clamping jaw can be tightened. The spring ring is provided with a connecting part, and the first clamping jaw extends into the connecting part and is connected with the connecting part in a clamped mode when tightened. In this way, the pushing piece only moves in the pushing pipe, the first clamping jaw contracts inwards when the spring ring is released, the occupied space is not increased when the spring ring is released, and therefore the possibility that other spring rings are hooked is reduced, and the possibility that the first clamping jaw makes contact
