| 摘要 |
The present invention is provided with a lower-jaw traction tool (19) to be attached to the lower jaw of a patient, a vibration mechanism (22) that applies vibration to the lower-jaw traction tool for treatment, and a traction mechanism (24) that applies a traction force to the lower jaw of the patient. The lower-jaw traction tool is attached to the vibration mechanism. The vibration mechanism is coupled to the traction mechanism by means of a flexible coupling body (23). When the vibration of the vibration mechanism and the traction force of the traction mechanism are simultaneously applied to the lower-jaw traction tool, the coupling body exhibits flexibility in the direction that prevents the vibration from being transmitted to the traction mechanism. This reduces direct transmission of the vibration to the patient and also reduces noise, thereby reducing stress on the patient and achieving comfortable treatment. |
