Description
本出願は、2003年5月8日に出願された米国仮出願第60/468,919号の利益を主張し、その開示は、本明細書によって参考として援用される。
(1.技術分野)
技術分野は、解剖学的空間を形成するためのバルーン切開器具、バルーン係留具、ならびに組合わせたバルーン切開器具およびバルーン先端カニューレを有する装置に関する。
種々の手術の間に、組織の層を切開し、その中で外科用器具が操作され得る解剖学的空間を形成することが必要である。例えば、ヘルニア修復手術では、筋膜組織層を切開し、そしてヘルニア部位に接近するために、腹膜外空間内に解剖学的手術腔を形成することが必要である。ヘルニア修復手術で用いられる組織切開手順を実施するための種々のバルーン切開器具が公知である。これらは、一般に、チューブの遠位端上に形成された切開バルーンを有する単一デバイス、およびチューブの近位端上に形成された膨張ポートを含む。このバルーン切開器具は、切開部中に挿入され、そしてバルーンは切開のために膨張される。切開後、および切開部からこのバルーン切開器具を取り出した後、カニューレがこの切開部中に挿入され、そして解剖学的空間中への外科用器具の導入のための接近経路を形成しながらガス注入するために用いられる。
Claims (6)
- バルーン切開器具とバルーン先端部カニューレとを組み合わせた外科用器具であって:
該バルーン切開器具が、切開器具ハウジング、該切開器具ハウジングから遠位方向に延びる切開器具チューブ、および該切開器具チューブの遠位端上に取り付けられた切開バルーンを備え;
該カニューレが、カニューレハウジングおよび該カニューレハウジングから遠位方向に延びるカニューレチューブを有するカニューレであって、該カニューレハウジングが該カニューレチューブの遠位端にバルーン係留具を備え、そして
該切開器具ハウジングおよびカニューレハウジングのうちの一方が、ラッチ構造を有し、そして該切開器具ハウジングおよびカニューレハウジングのうちの他方が、該ラッチ構造の受容のための凹部を有し、該カニューレハウジングが該ラッチ構造を含み、そして該切開器具ハウジングが該ラッチ構造の受容のための凹部を含み、該カニューレハウジングおよび切開器具ハウジングを一緒に取り外し可能に固定し、該バルーン切開器具が、該カニューレの保持リングを通り、該ラッチ構造および凹部が係合するように挿入され、バルーンが収縮するとき、該バルーン切開器具とバルーンが、該ラッチ構造を解放することによって一体となって取り出される、外科用器具。 - 前記ラッチ構造が、少なくとも1つの移動可能なアームを含む、請求項1に記載の外科用器具。
- 前記少なくとも1つの移動可能なアームが、前記凹部と係合可能なフックを含む、請求項2に記載の外科用器具。
- 前記カニューレハウジングに取り外し可能に取り付け可能であるシュラウドをさらに備える、請求項1に記載の外科用器具。
- 前記切開器具ハウジングに取り外し可能に取り付け可能である端部キャップをさらに備える、請求項1に記載の外科用器具。
- 前記バルーン係留具の少なくとも一部分を取り囲むスリーブをさらに備え、該スリーブが該バルーン係留具を収縮に向かって付勢する傾向にし、前記カニューレハウジングが該バルーン係留具と連通するバルブを有する、請求項1に記載の外科用器具。
