Novel root canal measuring method

Abstract

The invention relates to the technical field of medical instruments and discloses a novel root canal measuring method. The method comprises: 1) starting a root test and initializing a root test system, 2) if the root test system receives a calibration signal, carrying out calibration through a circuit, adjusting to an exact value and carrying out a root test through the root test system, 3) if theroot test system does not receive a calibration signal, transmitting a signal with frequency F1, 4) acquiring impedance through the root test system and transmitting a signal with frequency F2, and 5) acquiring impedance through the root test system and transmitting a signal with frequency F3. The novel root canal measuring method simplifies a multi-stage operational amplifier circuit only through performing the first-order amplification of the input signal and then acquiring and computing the signal through an AD5933 chip, needs a simple calibration process and only needs a calibration device of known impedance. In use, a user can calibrate the device through the same calibration method.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel root canal measurement method. Background technique [0002] Root canal therapy is a relatively complicated method of endodontic treatment. It uses many instruments and steps. It needs to go through multiple treatment steps and take multiple X-rays to complete the whole process. During and after the treatment, there may be There will be pain and other discomfort symptoms, most of which are normal reactions, and you can go back to the doctor according to the appointment time. If the pain is severe, accompanied by local swelling and systemic reactions, you should go back to the doctor in time and take further treatment as appropriate. During root canal treatment, doctors can only use X-rays or The root apex locator has a general understanding of the root canal system. In case of complex root canals (curved, narrow, calcified obstruction, broken instruments, side...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a new type of root canal measurement method, which has a structure that simplifies the measurement circuit, reduces the number of devices, reduces production and debugging time, and multi-point sampling, thereby filtering out the root canal in the oral cavity except for the patient tissue. Advantages, it solves the need to use multi-stage amplifiers to ensure accurate and reliable signals. In the production process, circuits using multi-stage operational amplifiers even need to place adjustable potentiometers step by step for calibration, and the production and debugging process is relatively long.
