摘　　要：目的:对现行高频电刀质量检测技术规范进行探讨,排除功率检测时检测人员的安全隐患,准确测量不同种类高频电刀的漏电流。方法:采用FLUCK QA-ESⅡ高频电刀分析仪对高频电刀的功率和漏电流进行检测。功率检测时,采用专用连接线连接高频电刀中性电极输出口与高频电刀检测仪功率输入口,取代常规中性电极板与夹子线连接的方法。漏电流检测时,对单极加载手术电极、单极加载中性电极、单极空载手术电极、单极空载中性电极4种连接方式下以地为基准和高频绝缘的2种高频电刀的漏电流数据进行重复测量,记录每项漏电流最大值。结果:功率检测时,改进后的连接方法和常规连接方法的检测值一致,且在实际操作中并未产生电火花。漏电流检测时,测量以地为基准的高频电刀时,空载下的漏电流为不合格数据;测量高频绝缘的高频电刀时,空载情况下的漏电流平均值更低,加载情况下的漏电流更接近临界值。结论:改进后的高频电刀功率检测方法对检测人员更加安全。对于以地为基准的高频电刀,测量加载情况下的漏电流,对于高频绝缘的高频电刀,测量空载情况下的漏电流可以更加真实地反映高频电刀的实际使用状态。Objective To discuss the technical specifications of current high-frequency electrotome detection, to avoid the hidden danger of high-frequency electrotome power detectors, and to measure the leakage current of different kinds of highfrequency electrotome accurately. Methods The power and leakage current of the high frequency electrotome were measured by FLUCK QA-ESⅡ high frequency electrotome analyzer. The safety of the two methods was compared before and after the improvement of the power measurement. Four parameters of leakage current were repeatedly measured with the ways of high frequency earthing and high frequency isolation respectively. The maximum measurement of leakage current was recorded.Results The improved connection method was safe in the power measurement. For the high-frequency electrotome in the model of high frequency earthing, the values of leakage current were restrained within the range of error with two ways of monopolar loading operation electrode and neutral electrode. For the high-frequency electrotome in the model of high frequency isolation, the values of leakage current were limited within the range of error withtwo ways of monopolar empty operation electrode and neutral electrode. Conclusion The improved high-frequency electrotome power detection method is safe for detectors. The data obtained from the leakage current detection method using the national standard correction method reflect the actual state of the high-frequency electrotome, when the electrotome with earth as the reference is used to detect the leakage current with loading or the insulated electrotome is applied to measuring the leakage current with no loading.
