Description

An automatic ligation processing device for orthodontics and its application method

technical field

The invention relates to an automatic ligation treatment device for orthodontics and a method for using the same, belonging to the technical field of medical equipment.

Background technique

In the process of orthodontic treatment, putting the arch wire into the bracket groove and tying it with the ligature wire is an essential operation link.

Orthodontic treatment puts the main arch wire in the bracket groove fixed on the tooth surface, binds it in the groove, and uses the elastic deformation of the main arch wire to apply force to the bracket, and then passes through the bracket Strengthen the teeth. Since the teeth are connected together by the root, periodontal ligament, and alveolar bone, when an orthodontic force is applied to the tooth, the alveolar bone on the compressed side undergoes bone resorption under the mediation of the periodontal ligament, and is stretched. The alveolar bone on one side undergoes bone formation under the mediation of periodontal ligament. By this principle, the tooth can be moved towards the compression side. Once the teeth move, the deformation of the main arch wire will be reduced, and the orthodontic force will also be weakened. Therefore, it is necessary to replace or adjust the main arch wire at regular intervals in order to exert the correct orthodontic force on the teeth. Orthodontics is to repeat the above-mentioned process continuously, so that the teeth move little by little, and finally move them to the desired position. The frequency of adjustment and replacement of the main arch wire is about once every month or two, at which time the ligature wire needs to be replaced.

The ligature wire is pre-formed by bending a metal wire into a "U" shape from its central part. The process of ligation is to hold both ends of the ligation wire with a needle holder or ligature forceps at the same time, and pass the "U" shaped part of the ligation wire under the bracket wing, then turn the needle holder to tighten the ligation. Bind both ends of the wire. After the binding is complete, use scissors to cut off the end of the ligation wire.

When using this method for ligation, in order to hold the ligation wire, you must always hold the needle holder. At the same time, during the ligation process, every time the needle holder is turned 180 degrees, the needle holder needs to be slid once in the hand. The above-mentioned process is repeated continuously to complete the ligation, which is very time-consuming and labor-intensive, and it is necessary to hold the scissors with the other hand to interrupt the end of the ligation wire, which further increases the workload and brings a lot of inconvenience to its work.
