Embodiment 1
[0059] see figure 1 , an intelligent control device for motor rotation of a root canal treatment instrument, characterized in that: it includes a depth detection component, a chip processing center, a buzzer alarm unit, and an LCD display; the depth detection component, the buzzer alarm unit, and the LCD display It is connected with the chip processing center, and the chip processing center is connected with the motor control;
[0060] The depth detection component includes an impedance measurement component and a current measurement component, the current measurement component is connected to the motor and monitors the current passing through the motor in real time when the motor is working, and immediately feeds back current information;
[0061] The root canal impedance measurement component is connected with the chip processing center, receives the dual-frequency or multi-frequency signal sent by the chip processing center in real time, and feeds back the measurement resul...
Embodiment 2
[0065] see figure 2 , an intelligent control method for motor rotation of a root canal treatment instrument, the steps are:
[0066] S101. Send a forward working command to the motor to make the motor rotate in the positive direction;
[0067] S102, the chip transmits signals of different frequencies to the measurement components,
[0068] S103. The chip reads the measured impedance value from the measuring part of the different frequency signals at the same position of the root canal when the motor is running.
[0069] S104. Comparing the impedance value at the position of the apical foramen according to the measured impedance value;
[0070] S105, judging whether the measured impedance value is close to the predetermined range, if it is greater than the predetermined range, then keep sending the forward working instruction to the motor and proceed to step S101;
[0071] S106. If the measured impedance value enters the predetermined range, determine whether the apex of th...
Embodiment 3
[0074] see image 3 , an intelligent control method for motor rotation of a root canal treatment instrument, the steps are:
[0075] S201. Send a forward working command to the motor to make the motor rotate in the positive direction;
[0076] S202, the chip transmits signals of different frequencies to the measurement component,
[0077] S203. The chip reads the measured impedance value from the measuring part of the different frequency signals at the same position of the root canal when the motor is running.
[0078] S204. Comparing the impedance value at the position of the apical foramen according to the measured impedance value;
[0079] S205, comparing whether the measured impedance value enters the first predetermined range, and judging whether the distance between the apex of the root canal file and the position of the apex of the tooth is greater than the first predetermined threshold range, and not sending a sounding command to the buzzer alarm unit;
[0080] S206...
