Description
上述の実施形態には、処置具20が超音波振動と高周波電力によって生体組織を処置する例を示した。しかしながら、生体組織を処置するエネルギ源はどのようなものでもよい。例えば、超音波振動のみによって生体組織を処置するものでもよいし、図8のように高周波電力のみによって生体組織を処置するものでもよい。
第2の変形例に係る処置部110の構成の模式図を図9に示す。本変形例では、揺動部材140の基端側が第1の把持部材120に接触しにくいように、図9に示すように、揺動部材140の基端側の第1の把持部材120と対向する部分Rが面取りされている。このような面取りによって、第1の把持部材120と揺動部材140とがさらに接触しにくくなる。
第1の把持部材120と揺動部材140とが開いており、生体組織がその間に挿入されるときを考える。図7に示す比較例のように、第1の把持部材220と揺動部材240とが接触するように構成されているとき、処置対象である生体組織は、揺動部材240にあたるために、揺動部材240よりも基端側に押し込まれにくい。これに対して、上述の実施形態の場合、第1の把持部材120と揺動部材140との間に間隙が存在する。このため、この間隙を通り、生体組織が揺動部材140よりも基端側に押し込まれることがある。生体組織が揺動部材140よりも基端側に位置すると、その部分において処置が行われなくなる。
本変形例でも第3の変形例と同様に、生体組織が揺動部材140よりも基端側に位置しないようにストッパが設けられている。本変形例に係る処置部110の概略を図13に示す。図13に示すように、本変形例では、第1の把持部材120と揺動部材140との間の間隙を塞ぐように、第2の把持部材130にストッパ136が設けられている。
