図1〜図6は、外科手術を行うために、図1Aに示すような非関節動作状態でトロカールカニューレ通路を通って患者の体内の手術部位まで挿入するように寸法決めされている、例示的な外科ステープル用及び切断用の器具(10)を図示している。外科手術、ステープル留め、及び切断する器具(10)は、実施部分(22)に接続されたハンドル部分(20)を含み、実施部分は、関節機構(11)において遠位方向に終端するシャフト(23)と、遠位方向に取り付けられたエンドエフェクタ(12)と、を更に備える。関節機構(11)及び遠位のエンドエフェクタ(12)がトロカールのカニューレ通路を通じて挿入された後、図1Bに図示されているように、関節制御(13)によって関節機構(11)を遠隔的に関節運動を行うことができる。そのようにして、エンドエフェクタ(12)は、所望の角度から又は他の理由のために、臓器の背後に到達する若しくは組織に近づくことができる。本明細書では、「近位」及び「遠位」といった用語は、器具(10)のハンドル部分(20)を握っている臨床医を基準として使用されていることを理解されたい。したがって、エンドエフェクタ(12)は、より近位のハンドル部分(20)に対して遠位である。便宜上、また説明を明確にするため、本願では「垂直」及び「水平」といった空間的な用語を図面に対して使用する点も更に認識されるであろう。しかしながら、手術器具は、多くの配向及び配置において使用され、これらの用語は、制限的及び絶対的であることが意図されない。
図7〜図8は、器具(10)などのステープリングデバイスの使用後に、治療薬を組織上に送達するための例示的なモジュラーエンドエフェクタ(100)を示す。図8に示すように、エンドエフェクタ(100)は、近位部(104)及び遠位部(106)を画定する外壁(102)を含み、遠位部(106)は、混合空間(108)と先端部(110)とを含む。単なる例として、先端部(110)及び外壁(102)は、参照によりその開示が本明細書に組み込まれる、2008年5月29日に公開された「Adhesive Dispenser for Surgery」と題される米国特許出願公開第2008/0121657号の教示に従って構成されてもよく、かつ動作可能であってもよい。
図9に示す別の形態では、前述のようなエンドエフェクタ(12)を用いた組織の切断及びステープル留めに伴う出血を低減するのを支援するために、上述のカートリッジ(37A)は、止血剤などの薬剤を収容する一体型発泡体ブロック(144)を備えていてもよい。図9は、前述のように組織を切断及び/又はステープル留めするように作動する器具(10)の下部つかみ具(16)のチャネルの中に取り外し可能に装着するための、カートリッジ(37A)の分解図を示す。カートリッジ底部(146)は、カートリッジ底部(146)の周壁によって画定されるチャンバ(148)を含んでおり、その中に発泡体ブロック(144)が挿入される。ステープル(47)は発泡体ブロック(144)の中にあらかじめ装着されていてもよい。あるいは、ブロック(144)は、ステープル(47)と、蓋(150)などのカートリッジデッキの下側との間に位置付けられてもよい。ステープル(47)は、鉄、ニッケル−チタン合金、ステンレス鋼、及び/又はチタンから選択される材料を含み得る。もちろん、任意の他の好適な材料を使用してステープル(47)を形成することが可能である。
