Technical Field

The utility model relates to the field of medical equipment, in particular to a ligature ring placer for orthodontic operation.

Background

In the orthodontic process, the orthodontic arch wire needs to be fixed in a groove on the orthodontic bracket by a ligature ring. Moreover, with the development of modern technology, in order to simplify ligation modes, the ligation is performed by adopting a rubber ligature ring at present, and only the ligature ring needs to be directly hung on a ligation wing of an orthodontic bracket, so that the operation is simple. However, since the diameter of the rubber ligature ring is small and the rubber ligature ring has certain elasticity, the ligature ring needs to be firstly expanded by a placer during operation and then hung under the ligating wing of the orthodontic bracket.

Most of the conventional placers are forceps placers and gun placers, and when the forceps placers are used, the ligature ring has large elastic tension, so that the forceps placers are inconvenient to unfold and difficult to operate; the gun type placer is expensive, and the condition that the ligature ring is not placed in place easily occurs during operation, so that the use reliability is poor.
