Technical Field

The invention relates to a replaceable double-needle-tube hot gutta-percha filling handle, belonging to the technical field of medical instruments.

Background

Currently, the filling handles commonly used for filling with root canal gutta-percha are divided into two categories: a manual filling type and an automatic filling type. The manual filling handle structure of the current mechanical trigger structure is large, the operation is not stable and convenient enough for doctors, the filling effect can be influenced, and on the other hand, the battery consumption speed of the automatic filling handle is very high, and meanwhile, the charging time is long, so that the use efficiency is very low.

Because the existing root canal therapy operation can treat one tooth or two parallel close-distance teeth at one time, the tooth with two or more canals needs to be sequentially filled with root canals, and longer time is needed.
