摘要 目的 探讨集束高频电针热凝治疗装置的国产化和超声引导下集束高频电针热凝临床应用的可行性。 方法 采用国产集束高频电针和国产 GD35 0型高频电刀仪与美国达隆公司 RF2 0 0 0集束电极和射频发生仪进行实验对照。在室温 17℃、19℃及 2 2℃条件下 ,分别对 30个离体猪肝进行实验 ,离体猪肝置于电极板上 ,浸泡于生理盐水中。实验时达隆公司射频仪与国产 GD35 0型高频电刀仪输出功率均自 2 0 W起 ,每分钟升高 10 W至电流迅速变小时关闭装置。实验过程中 ,国产化装置及国外装置都采用自行研制的感应电流表显示电流变化 ,GE2 0 0 Pro7.5 MHz浅表探头监护离体猪肝声像图改变。术后 2 h测量坏死体积 (按 V=1/ 2 d1 d2 d3计算 )。对国产和国外装置实验结果采用配对检验比较 ,对超声引导下测量的坏死范围与术后剖视测量的坏死范围进行相关分析。 结果 国产装置和国外装置离体猪肝凝固坏死体积差异无统计学意义 (t=0 .5 3,P>0 .0 5 )。国产集束高频电针与国外 RF2 0 0 0伞形多弹头电极的热凝固坏死体积差异无统计学意义 (分别为 t=0 .36 ,P>0 .0 5 ;t=0 .16 ,P>0 .0 5 )。超声测量坏死范围与术后剖视测量坏死范围有较好的相关性 (r=0 .6 7,P<0 .0 1)。 结论 国产装置与国外装置相比实验效果相近 。 Objected\ To study the feasibility of using the domestic cluster electrode needles and the heating coagulation therapeutic device and explore its clinical application under the guidence of ultrasound.\ Methods\ The experiment results of the domestic electrode needles and GD\|350 electrotome were compared with RF2000 cluster electrode needles and its generator.\ At 17,19 and 22 ℃ room temperature, 30 ex vivo pig livers were used to perform the experiment respectively.\ The liver tissues layed on the electrod...
