Description
この実施態様では、処置部の先端面部の保持部によって処置対象を保持する一方で、超音波振動子で超音波振動を発生し、発生された超音波振動を処置部へと伝達し、処置部の先端面部を処置対象に押圧して超音波振動を付与することにより、処置対象に処置を行う。
また、処置部の周面部に形成されている指標により、処置部の先端面部の保持部の特徴を識別する。
この好ましい実施態様では、先端面部の凹部に処置対象を嵌入して処置対象を保持する。
この好ましい実施態様では、先端面部の凸部の側面部に処置対象を係合させて処置対象を保持する。
この好ましい実施態様では、先端面部の粗面部と処置対象との摩擦により処置対象を保持する。
この好ましい実施態様では、ナイフ状のエッジ部によって、処置対象に切開処置を行う。
この好ましい実施態様では、チャンネルを介して、先端面部の開口部から送液、吸引等を行う。
この好ましい実施態様では、先端面部では、開口部以外の部分によって処置対象に処置を行う。
この好ましい実施態様では、処置部が交換可能である。
この好ましい実施態様では、太径部が交換可能である。
この好ましい実施態様では、耐久性の高いセラミックで先端面部を形成している。
本発明のさらに別の実施態様は、上記太径部である。
本発明のさらに別の実施態様は、上記振動伝達部材及び処置部を具備するプローブである。
また、処置部の先端面部を視認することが難しい場合であっても、処置部の周面部の指標を視認することによって、先端面部の保持部の特徴を認識することが可能となっている。
また、細長い隆起部が形成されている生体組織を保持する際には、振動伝達部材28を軸回り方向に回転操作して、隆起部の向きに第1あるいは第2の凹部53a,53bの向きを合せる必要がある。ここで、第1及び第2の凹部53a,53bは互いにほぼ直交しており、第1の凹部53aと第2の凹部53bとの内、少ない回転操作量で隆起部と向きを合わせることができる凹部53,53bを生体組織の保持に用いている。このため、向きを合わせる操作が容易となっている。
また、処置部36の先端面部46を生体組織に近接させる際には、処置部36の先端面部46を視認することが難しくなる。本実施形態の指標64a,64bは処置部36の周面部48に配置されているため、処置部36の先端面部46を視認することが難しい場合であっても、周面部48の指標64a,64bを視認することにより保持部の特徴を認識することが可能となっている。
