    • The invention concerns an electrode for HF surgery and in particular for the vaporisation of tissue, said electrode having at least one rolling electrode body, which comes into contact at least in part with the tissue to be treated, and at least one lead, via which the electrode body is connected to an HF supply unit. The invention is characterised in that, in the region which comes into contact with the tissue, each electrode body has a smooth surface, in that the smooth surface is provided with regions of low electrical conductivity and a plurality of regios of high electrical conductivity which are discontinuous in the surface, and in that the regions of high electrical conductivity are at least partially mutually connected in the electrode body.
    • 公开了一种用于高频手术的电极,更具体地汽化组织,具有至少一个滚动电极体,附带至少部分地与待处理组织接触,并通过该电极体连接到HF供给单元的至少一个进料管线。 本发明的特征在于,每个电极体具有在与组织接触的面积的光滑表面来,在低导电性的光滑的表面区域和在高导电性的非连续区域的表面上的多个 是提供,而高导电率的区域彼此至少部分地连接在电极体。
