Abstract
Description
[1−1.構成]
図1に示す医療用処置具1は、高周波電圧によって、生体組織の切開、凝固等を行うための処置具である。
第1アーム2は、第1端部2Aと第2端部2Bとを有し、第1端部2Aから第2端部2Bまで延伸する板状又は棒状の部材である。同様に、第2アーム3は、第1端部3Aと第2端部3Bとを有し、第1端部3Aから第2端部3Bまで延伸する板状又は棒状の部材である。
図2に示すように、第1アーム2は、導体21と、支持体22と、カバー23とを有する。
導体21は、第1アーム2の第1端部2Aから第2端部2Bまで延伸した棒状の部材である。導体21には、後述するコード5から電流が供給される。
支持体22は、樹脂(つまりマトリクス)と強化材との複合材(いわゆる強化プラスチック)を主成分とする層である。ここで、「主成分」とは、90質量%以上含まれる成分である。複合材に用いられる樹脂は、特に限定されず、熱硬化性樹脂又は熱可塑性樹脂が使用できる。複合材に用いられる強化材としては、例えば、繊維、粒体等が挙げられる。複合材に用いられる繊維としては、例えば、ガラス繊維、炭素繊維等が挙げられる。粒体の形状としては、球体、多面体、筒体等が挙げられる。
カバー23は、導体21及び支持体22を被覆する部材である。カバー23は、支持体22の全体と、導体21のうち先端部21A以外の部分とを被覆している。カバー23は、使用者が把持する把持部を構成する。
第2アーム3は、第1アーム2と同様の導体21と、支持体22と、カバー23とを有する。ただし、第2アーム3では、支持体22は、導体21に対し第1アーム2とは反対側に配置される。
第1アーム2及び第2アーム3は、例えば、以下の手順で製造できる。まず、導体21に、支持体22を構成する複合材シートを重ねる。さらに、導体21と複合材シートとを挟むように、カバー23を構成する2つの樹脂シートを重ね合わせる。この積層体を加熱しながら各部材を圧着させることで、第1アーム2及び第2アーム3が得られる。
連結部4は、図1に示すように、第1アーム2の第1端部2Aと、第2アーム3の第1端部3Aとに取付けられている。
コード5は、2つの電線を有するバイポーラコードである。各電線は、連結部4内にて、それぞれ第1アーム2の導体21と、第2アーム3の導体21とに電気的に接続されている。
差し込みプラグ6は、コード5に電気的に接続されている。差し込みプラグ6は、高周波電流発生装置(図示省略)に接続される。
以上詳述した実施形態によれば、以下の効果が得られる。
以上、本開示の実施形態について説明したが、本開示は、上記実施形態に限定されることなく、種々の形態を採り得ることは言うまでもない。
