Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a hot-melt gutta-percha filling device for filling teeth.

Background

Tooth filling refers to a method for repairing a tooth defect by using artificial substances, and comprises two main steps of cavity preparation and filling. Artificial substances for repairing teeth are called filling materials. When the pathological changes have spread to the pulp and even cause periapical disease, the pulp should be treated first and then the teeth should be filled. Root canal therapy is the most effective treatment method commonly used for endodontic and apical periodontal diseases, and the principle of root canal surgery for teeth is to remove most of the infectious materials in the root canal by mechanical or chemical means, and to prevent the occurrence of apical periodontal disease or to promote periapical healing of the diseased root canal by filling the root canal and sealing the crown. In root canal surgery, a loose root canal filling, overfilling or underfilling can result in a different degree of failure of the root canal procedure. One of the most common methods for root canal filling is to inject gutta-percha into the root canal under pressure after heating and hot melting by a heating element of a gutta-percha filling gun. Current gun type injecting glue filling apparatus, it need reciprocal trigger of pulling, thereby make the push rod move forward always and extrude the hot-pressing glue, but this equipment is the dynamics that the trigger was do not mastered well to the doctor to the volume of gluing of extruding is great difference, and manual control makes the doctor hardly hold accurate filling glue volume, has reduced work efficiency, still has the risk that misleading the doctor to fill the root canal and arouse root canal therapy failure even, wastes time and energy. After the gum stick in the rifle finishes using, it is troublesome time-consuming arduous to change the gum stick, can't add the gum stick to gum melting intracavity automatically. Meanwhile, the filling needle can not extrude gutta-percha to the deep part of the root canal, and the subsequent operation of a dentist is needed, so that the working efficiency is low.
