Abstract
【課題】経自然開口的に導入した観察装置により管腔器官の特定部位をより容易に確認できる方法及びそのための装置を提供する。
【解決手段】本発明の経自然開口的な医療行為は、管腔器官のターゲット部位の近傍に、腹壁側から穿刺具を刺入し、前記穿刺具の先端を管腔器官の内側に突出させることと、生体の自然開口を通して前記管腔器官に観察装置を導入し、前記穿刺具を指標として確認することにより、前記管腔器官におけるターゲット部位を設定することと、前記観察装置で確認したターゲット部位に対して、自然開口を通して挿入した処置具を用いて処置をすることとを含む。
【選択図】図8
Description
図1(a)及び図1(b)にデバイスの一例としての内視鏡を示す。内視鏡1は、術者が操作する操作部2から患者の体内に挿入される挿入部3が延びている。挿入部3は、長尺で可撓性を有している。挿入部3の先端4は、操作部2のアングルノブ5で湾曲させることができる。図2に示すように、挿入部3の先端面3Aには、体内を観察する観察装置6及び照明装置7が配設されている。観察装置6としては、例えば、対物レンズなどの観察光学系と、撮像素子としてのCCD(Charged Coupled Device)とを有して構成される。照明装置7は、体外の光源装置から光ファイバで照明光を導く構成を有する。撮像素子からの出力信号は、挿入部3内に通した信号線を通じて後述する制御装置24に伝送するように構成しても良い。また、撮像素子からの出力信号を無線で制御装置24に伝送するように構成しても良い。さらに、照明装置7として、公知の発光素子(例えば、発光ダイオード)などを用いて構成しても良い。
