Description
本出願は、2012年4月4日出願の米国特許出願番号13/439,639(代理人整理番号第346号)の優先権を主張するものであり、その開示内容全体は引用により本明細書に組み込まれている。
ユーザは、手術用具2を持つ。エンドエフェクタ4は、組織に対する所望の位置の近くに位置決めされる。好都合には、エンドエフェクタ4は、トロカールポート又は他の低侵襲開口部を通って体内に進む。エンドエフェクタ4がステープルホルダー8及びアンビル6を含む場合、エンドエフェクタ4は開くことができ、少なくともアンビル6の遠位端がステープルホルダー8から離間して、組織をその間に位置付けることを可能にするようになっている。しかしながら、エンドエフェクタ4は、組織を処置するための任意の他の用具とすることができる。
