Abstract

A root canal treatment device relates to the technical field of dental treatment instruments. The root canal treatment device comprises a contra-angle hand-piece (10) and a root canal file (20) detachably connected to the contra-angle hand-piece (10), and further comprises a drive module (30) in transmission connection with the root canal file (20), the drive module (30) comprises a rotation driver (31) and a vibration generator (32), wherein the rotation driver (31) is configured to drive the root canal file (20) to rotate axially, so as to mechanically cut and ream the root canal, thus shaping the root canal, and the vibration generator (32) is configured to drive the root canal file (20) to vibrate radially. Vibration of the root canal file (20) at a specific frequency can sufficiently activate the activity of the drug material filled in the root canal, especially in the process of filling the drug material into the root canal, the vibration provided by the vibration generator (32) and the rotation of the root canal file (20) that are carried out simultaneously can efficiently discharge the air bubbles in the drug material filled in the root canal, so that the drug material can be tightly filled into the root canal, thereby providing a better environment for subsequent root canal treatment, improving the effect of root canal treatment, and relieving the patients' pain.
