Description
本発明の第1の実施形態について図面を参照して説明する。本実施形態に係る治療用処置装置は、生体組織の治療に用いるための装置である。この治療用処置装置は、生体組織に高周波エネルギと熱エネルギとを作用させる。治療用処置装置300の外観の概略を図1に示す。この図に示すように、治療用処置装置300は、エネルギ処置具310と、制御装置370と、フットスイッチ380とを備えている。
なお、ここで示したエネルギ処置具310の形状は、もちろん一例であり、同様の機能を有していれば、他の形状でもよい。例えば、保持部やハンドルや操作ノブが図1に示す形状とは異なる形状をしていてもよいし、シャフトが湾曲していてもよい。さらに、エネルギ処置具310は、生体組織を把持する鉗子型に限らず、生体組織に押し付けて用いるこて型の処置具でもよい。
第2の実施形態について説明する。ここでは、第1の実施形態との相違点について説明し、同一の部分については、同一の符号を付してその説明を省略する。本実施形態では、第1の電極部100において、第1の高周波電極110、電熱変換素子140及び第1の高周波電極用通電ライン162の構成が第1の実施形態に係る第1の電極部100と異なる。
