Ultrasonic scaler tip and ultrasonic scaler

摘要

An ultrasonic scaler tip and an ultrasonic scaler having high sterilizing effect are provided. To provide a toothbrush with less impact on the mouth. An ultrasonic scaler chip has a chip body and an optical fiber. The tip body 11 is tubular, has a front end opening and a rear end opening, has a rear end that can be attached to the ultrasonic scaler body 2, and has a curved portion 16 in the middle. The optical fiber 12 is thinner than the minimum inner diameter of the chip body 11 and has a rear end capable of receiving light from a light source. The optical fiber 12 is inserted from the rear end opening to the front end opening of the chip main body 11, and the intermediate portion is in contact with the bending portion 16 so that the front end vibrates due to ultrasonic vibration of the chip main body 11. The ultrasonic scaler body 2 accommodates the liquid supply means, the ultrasonic generation means, and the light source, and is attached to the rear end of the ultrasonic scaler chip 1. The light source makes light in a predetermined wavelength region to be sterilized enter the rear end of the optical fiber 12. [Selection] Figure 1
