Abstract
Description
背景技術
図1は、本発明を理解するのに有用である、GB2486343に開示されているような電気手術装置400の概略図を示す。本装置は、RFチャネル及びマイクロ波チャネルを備える。RFチャネルは、生体組織の治療(例えば、切開または乾燥)に適した電力レベルでRF周波数電磁信号を生成し制御するための構成要素を含む。マイクロ波チャネルは、生体組織の治療(例えば、凝固または焼灼)に適した電力レベルでマイクロ波周波数電磁信号を生成し制御するための構成要素を含む。
図2は、本発明の実施形態によるマイクロ波増幅器配列100の概略システム図を示す。本増幅器配列100は、例えばマイクロ波エネルギーのみが必要とされる状況のために、独立型ジェネレータとして使用し得る。あるいは、増幅器配列100は、上記の種類のジェネレータに組み込まれてもよい。増幅器配列100は、電気手術器具から送出すべきマイクロ波周波数電磁(EM)エネルギーの高出力パルスを生成するように構成される。
