(技術分野)
本開示は、外科手術ファスナーまたはステープルを体組織に適用するための外科手術器具に関し、特に、末端−末端吻合ステープリング装置に用いられる外科手術バットレスに関する。
吻合は、別々の中空器官セクションを外科手術的に連結することである。一般的に、吻合手順は、中空組織の病気または欠陥のセクションが除去される外科手術に続き、残りの末端セクションが連結される。所望の吻合手順に依存して、末端セクションは、円形か、末端−末端か、または側−側の器官再構成方法によって連結される。
本開示の実施形態に従って、環状アレイの外科手術ステープルを用いて2つの中空器官セクションを連結するための装置が提供される。装置は、ステープルカートリッジコンポーネントと、アンビルコンポーネントと、ナイフ部材と、バットレスマウントと、バットレス部材とを含む。ステープルカートリッジコンポーネントは、環状アレイの複数の外科手術ステープルを含む。アンビルコンポーネントは、外科手術ステープルを変形させるための複数のステープルポケットを規定する。アンビルコンポーネントは、ステープルカートリッジコンポーネントとアンビルコンポーネントとの間に組織を調整可能にクランプするために、間隔を空けられた位置と接近された位置との間にステープルカートリッジコンポーネントに対して移動可能である。ナイフ部材は、ステープルカートリッジコンポーネントの複数の外科手術ステープルと同心状に配列されている。ナイフ部材は、ナイフ部材を通る管腔を規定する。ナイフ部材は、ステープルカートリッジコンポーネントに対して移動可能である。バットレスマウントは、少なくとも部分的にナイフ部材の管腔内に同心状に配置されている。バットレスマウントは、外側へ半径方向に延在する複数のスポークと、ナイフ部材の内壁と取り外し可能に固定された複数のレッグとを含む。バットレス部材は、バットレスマウントの複数のスポークと固定されている。バットレス部材は、複数の外科手術ステープルと同心状に整列されている。
