摘要

第1部分，见同上，第35-6页(1993)。本文讨论了经尿道电外科手术中常用的各种冲洗液对线性电极位移的影响。频率和电极类型保持不变。采用双极结构。结果表明，甘氨酸自来水、蒸馏水和无菌水等溶液对交流施加信号表现出电容性响应。电极浸泡在甘氨酸、蒸馏水和无菌水中均未出现电弧。完全了解电极分离和其他参数(如冲洗溶液)的影响可以帮助工程师设计出无危害的电手术器械

Voltage-current characteristics of an AC arc for different electrode separations with application to electrosurgery II

For pt. I, see ibid., p.35-6 (1993). A study of the effect of linear electrode displacement in various irrigant solutions commonly used during transurethral electrosurgery is discussed. Frequency and electrode type were held constant. A bipolar configuration was used. Results indicated that solutions such as glycine tap water, distilled water and sterile water displayed a capacitive response to the AC applied signal. Electrodes immersed in glycine, distilled water, and sterile water showed no arcing. A complete understanding of the effects of electrode separation and other parameters such as irrigant solutions may help engineers to design hazard free electrosurgical apparatus.<>
