Claims (15)
- 眼科における外科的処置で使用される装置において、
遠位端の貫通部分と近位端の受容部分を備えるトロカールカニューレであって、前記貫通部分は眼の内部へと延びるように構成され、前記受容部分と前記貫通部分を通じて外科用器具に前記眼の前記内部へのアクセスを提供するように構成され、前記アクセスは前記トロカールカニューレの進入軸に沿っている、トロカールカニューレと、
前記外科用器具の少なくとも一部の前記トロカールカニューレの前記進入軸との整列を案内するような形状の、前記受容部分におけるガイダンスバルブであって、前記外科用器具が前記トロカールカニューレを利用して前記眼の前記内部にアクセスするとき、前記眼の眼内圧と前記眼の外部の周囲圧力との間の平衡化を限定するガイダンスバルブと、を含む装置。 - 前記ガイダンスバルブは、直径において前記遠位端に向かって減少し、前記外科用器具の前記トロカールカニューレの前記進入軸との整列を案内する円筒形の空洞を含む、請求項1に記載の装置。
- 前記ガイダンスバルブは、前記周囲圧力にさらされる凹面を含み、前記凹面は前記外科用器具の前記トロカールカニューレとの軸方向の整列を案内する形状である、請求項1に記載の装置。
- 前記外科用器具の前記少なくとも一部はカニューレの柔らかい先端を含み、前記ガイダンスバルブは、前記外科用器具が前記トロカールカニューレを利用して前記眼の前記内部にアクセスする際に、前記柔らかい先端をまっすぐに保つ形状である、請求項1に記載の装置。
- 前記ガイダンスバルブは前記眼内圧にさらされる凸面を含み、前記眼内圧は前記凸面を前記外科用器具に押し付けて、前記外科用器具が前記トロカールカニューレを利用して前記眼の前記内部にアクセスする際に、前記眼内圧と前記周囲圧力との間の平衡化を限定する、請求項1に記載の装置。
- 前記ガイダンスバルブは前記眼内圧にさらされる凸面を含み、前記眼内圧は前記凸面に、前記外科用器具が前記トロカールカニューレから抜き取られる際に、前記眼の前記眼内圧と前記眼の外部の前記周囲圧力との間の平衡化を限定させる、請求項1に記載の装置。
- 前記外科用器具は柔軟な先端を含む、請求項1に記載の装置。
- 前記外科用器具の先端はカニューレを含む、請求項7に記載の装置。
- 前記ガイダンスバルブは、前記外科用器具の前記トロカールカニューレとの軸方向の整列を案内する形状のシリコン、ポリウレタン、又はポリイミドを含む、請求項1に記載の装置。
- 前記ガイダンスバルブから前記トロカールカニューレの前記軸までの距離は、前記遠位端に向かって減少して、前記外科用器具の前記トロカールカニューレとの軸方向の整列を案内する、請求項1に記載の装置。
- 前記ガイダンスバルブは、その中を通過する外科用器具に追従して、前記外科用器具が前記トロカールカニューレを利用して前記眼の前記内部にアクセスする際に、前記眼内圧と前記周囲圧力との間の平衡化を限定する開口を含む、請求項1に記載の装置。
- 前記開口は膜の1つ又は複数のスリットを含む、請求項11に記載の装置。
- 前記ガイダンスバルブは、追従して前記ガイダンスバルブと前記外科用器具との間のシールを確立し、前記外科用器具が前記トロカールカニューレを利用して前記眼の前記内部にアクセスする際に、前記眼内圧と前記周囲圧力との間の平衡化を限定する開口を含む、請求項1に記載の装置。
- 前記眼内圧は前記ガイダンスバルブを前記外科用器具に押し付け、前記外科用器具は前記トロカールカニューレを利用して前記眼の前記内部にアクセスする際に、前記眼内圧と前記周囲圧力との間の平衡化を限定する、請求項1に記載の装置。
- 前記ガイダンスバルブは、前記外科用器具の前記トロカールカニューレとの軸方向の整列を案内する漏斗形状を含む、請求項1に記載の装置。
