A New High-Frequency Electrotome Output Detection System
To prevent the patient from being cauterized by exceeding output of high-frequency electrotome and also assist the adaptive power control system, it was necessary to design a kind of system which was able to detect the target impedance according to the electrical parameters such as voltage and current that generated by the high-frequency electrotome. The system took the output of the electrotome as the input of the detection module, which passed through insulated voltage and current sensing circuit, signal conditioning circuit and then sampled by Data Acquisition (DAQ) board, oversampling was used to improve the signal-to-noise ratio, the data was processed and stored in LabVIEW program that based on PC, and finally calculated the final results and displayed it on the monitor. The results indicated that the system could detect the output parameters and target impedance accurately. So it can assist the adaptive power control and help to prevent patients from being burned in operation.
