Description
高周波駆動装置3では、従来のモノポーラ型電気メス装置と同様に、「Cut-Pure」(止血成分をほとんど含まない(又は凝固処置が不要な)切開出力)、「Cut-Blend」(ある程度の止血成分を含む切開出力)、「Coag-Soft」(剥離成分の弱い凝固出力)、「Coag-Hard」(剥離成分の強い凝固出力)、「Coag-Spray」(組織の広い範囲を一様に放電止血するために使用する凝固出力)、の各々の出力モードでの高周波出力が可能となっている。超音波駆動装置2では、「On」(超音波振動の振幅が設定値を維持する超音波出力)、「Auto」(超音波振動の振幅が高周波出力時のインピーダンス値に連動して変化する超音波出力)、の各々の出力モードでの超音波出力が可能となっている。これらの高周波出力と超音波出力の組み合わせに対して、それぞれに番号が付与されている。後述する操作表示パネルにおける設定の際に、選択された出力モードが番号により表示される。
ここで、xは超音波振動の振幅(peak to peak値)、frは超音波振動の共振周波数である。すなわち、「100%」設定では、frが23.5kHzのときxは約100μm〜300μmの範囲が好適し、frが47kHzのときxは50μm〜150μmの範囲が好適する。
先ず、対極板9を手術対象となる生体組織に密着させる。
図15は、第2の実施形態に係る手術用処置装置の外観構成を示している。ここでは、前述した第1の実施形態と異なる部分のみ説明する。
