【摘要】：对电外科仪器输出的高压和大电流参数进行准确检测是研制反馈式电外科仪器的基础。为此,本文研制基于PC机的输出参数测量系统,对电外科仪器输出的高压和大电流信号进行隔离感应、放大、滤波、差分信号变单端信号、有效值转换,最后通过DAQ采集卡进行模数转换,数据送入PC机中使用Labview软件进行过采样、显示和存储等处理。实验结果表明,该系统能够对电外科仪器的输出参数进行稳定测量,结果准确。因此,该系统的研制是成功的,在此基础上开发嵌入式的输出参数测量系统,能够为智能式的电外科仪器开发提供准确的反馈信息。
[Abstract]:The accurate detection of high voltage and high current parameters of electric surgical instruments is the basis of the development of feedback electric surgical instruments. For this reason, an output parameter measurement system based on PC is developed in this paper. The high voltage and high current signals outputted by electric surgical instruments are isolated and induced, amplified, filtered, differential signals become single-ended signals, and the effective values are converted. Finally, the analog-to-digital conversion is carried out through DAQ acquisition card, and the data is sent to PC for over-sampling, display and storage by Labview software. The experimental results show that the system can measure the output parameters of electric surgical instruments stably, and the results are accurate. Therefore, the development of the system is successful, on the basis of which the embedded output parameter measurement system can provide accurate feedback information for the development of intelligent electrical surgical instruments.
