Abstract
Description
本出願は、2019年3月29日に出願された米国仮特許出願第62/825,839号の優先権を主張する。
本発明は、電気外科手術器具に関し、より具体的には、高誘電率を有する電気外科手術電極用コーティングに関する。
血管シーラーなどの電気外科手術器具は、外科的処置に一般的に使用されるツールとなっている。これらの装置は、静電容量結合を介して治療される組織の切断および/または凝固を実施する目的で、治療される組織に直接的かつ静電容量結合される一つまたは複数の電極に電磁エネルギーを送達することによって動作する。すべての電極が直接(抵抗)結合および静電容量結合を介して電気を伝導する一方で、ほとんどの電極は、本質的に抵抗熱を生成する抵抗結合に主に依存する。したがって、当技術分野において、発生する抵抗熱の量を低減するために電極の静電容量結合を向上させることができる方法に対するニーズが存在する。
Claims (12)
