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。
より特定すれば、本願発明は以下の項目に関し得る。
(項目1)
外科用器具であって、以下:
切開器具ハウジング、上記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、および上記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有するバルーン切開器具;
カニューレハウジングおよび上記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、上記カニューレハウジングが上記カニューレチューブの遠位端にバルーン係留具を有するカニューレ、
を備え、そして
上記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、そして上記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、上記ラッチ構造の受容のための凹部を有する、
外科用器具。
(項目2)
上記カニューレハウジングが上記ラッチ構造を含み、そして上記切開器具ハウジングが上記ラッチ構造の受容のための凹部を含み、上記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する、項目1に記載の外科用器具。
(項目3)
上記ラッチ構造が、少なくとも1つの移動可能なアームを含む、項目1に記載の外科用器具。
(項目4)
上記少なくとも1つの移動可能なアームが、上記凹部と係合可能なフックを含む、項目3に記載の外科用器具。
(項目5)
上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、項目1に記載の外科用器具。
(項目6)
上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、項目1に記載の外科用器具。
(項目7)
上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、上記スリーブが上記バルーン係留具を収縮に向かって付勢する傾向にし、上記カニューレハウジングが上記バルーン係留具と連通するバルブを有する、項目1に記載の外科用器具。
(項目8)
バルーン先端部カニューレであって:
カニューレハウジング;
上記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;
係留バルーンであって、上記係留バルーンの対向する端部が、上記カニューレチューブに固定されている係留バルーン;および
上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であって、上記スリーブが上記バルーン係留具を収縮に向かうよう付勢する傾向にある、スリーブ、を備える、バルーン先端部カニューレ。
(項目9)
上記係留バルーンが、ウレタン材料から形成される、項目8に記載のバルーン先端部カニューレ。
(項目10)
上記スリーブの対向する端部の各々の周りに位置するリングをさらに備える、項目8に記載のバルーン先端部カニューレ。
(項目11)
各リングが、熱収縮可能な材料から形成される、項目10に記載のバルーン先端部カニューレ。
(項目12)
係留バルーンをカニューレチューブに固定する方法であって:
係留バルーンの対向する端部をカニューレチューブに固定する工程;および
上記係留バルーンの周りにスリーブを配置する工程、
を包含する、方法。
(項目13)
可撓性の上記スリーブが、上記スリーブの対向する端部の周りに付与されたバンドによって、上記係留バルーンの上に固定される、項目12に記載の方法。
(項目14)
上記バンドが熱収縮可能な材料から形成され、そして上記スリーブの対向する端部の周りで熱収縮され、上記スリーブを上記係留バルーンの上に固定する、項目13に記載の方法。
カニューレをウレタンコーティングに浸漬し、次いで、熱溶接を用いて、ウレタン膜をそのコーティングされたカニューレに取り付けることによって形成される。その膜は、次いで、RTVでコーティングされ、熱収縮チューブカラーは、その溶接された端部においてスリーブを強化する。あるいは、そのバルーン係留具304は、図4A〜4Dと関連して、上記で議論されるように取り付けられ得る。
Claims (3)
- 係留バルーンをカニューレチューブに固定するためのシステムであって:
係留バルーンの対向する端部をカニューレチューブに固定する手段;および
該係留バルーンの周りにスリーブを配置する手段、を備える、システム。 - 可撓性の前記スリーブが、該スリーブの対向する端部の周りに付与されたバンドによって、前記係留バルーンの上に固定される、請求項1に記載のシステム。
- 前記バンドが熱収縮可能な材料から形成され、そして前記スリーブの対向する端部の周りで熱収縮され、該スリーブを前記係留バルーンの上に固定する、請求項2に記載のシステム。
