RF NEUTRAL ELECTRODE DEVICE FOR APPLICATION OF RF CURRENT ELECTROSURGICAL SYSTEM COMPRISING A CORRESPONDING NEUTRAL ELECTRODE DEVICE AND METHOD FOR PRODUCING A NEUTRAL ELECTRODE DEVICE

摘要

The present invention relates to a neutral electrode device for use in the application of an RF current to a living tissue, the neutral electrode device comprising: - a support structure 40 having first and second sides; - at least one electrode 34 , 34 ′ arranged on the first side of the support structure 40 . - a phase change material (PCM) for absorbing heat, disposed on the second side of the support structure (40); The phase change material is formed at least in part as blocks 37 , 37 ′ and the blocks 37 , 37 ′ are at least partially spaced apart from each other to form voids 38 , 38 ′ to form the support structure 40 . placed on the second side of
