Description
本発明は、患者の目の角膜を切開するための外科システムに関する。
目の角膜を切開する、特に、目に内的なポケットを形成する改善されたシステムおよび方法が提供される。これらシステムおよび方法は、比較的大きい幅または径を有するポケットを設ける一方で比較的小さい最初の切り込みを用いて角膜のポケットを形成する。
好ましい面では、本発明は、角膜の層を分離することでポケット、フラップ、または、キャップを形成するよう生きているまたは提供される角膜を切開するために使用される角膜外科システムを提供する。具体的には、本発明は、生きているまたは提供される角膜の層間に、様々な形状および大きさの、ある均一な深さのポケットを自動的に形成するシステムを提供する。本発明は、生きているまたは提供される角膜に角膜組織のフラップまたはキャップを形成するためにも使用される。
Claims (5)
- 目の角膜を切開するシステムであって、
X軸およびY軸を規定するフレームであって、前記角膜の外側で不動であり得るフレームと、
遠位端に切開要素を備える可動部材であって、前記フレームに対して移動可能に、ホイールに取り付けられているピボット上に移動可能に取り付けられ、前記切開要素を、前記角膜中の小さな初期切開を通って前記角膜の内側に非切開角膜中に進める可動部材と、
前記可動部材に連結されるピボットを運ぶホイールを備える第1のプログラム可能な駆動部であって、円形路上のピボット上で前記可動部材を運ぶ前記ホイールを回転させるよう適合される第1のプログラム可能な駆動部と、
前記ピボット上の前記可動部材を回転するために前記可動部材に連結されるギアを備える第2のプログラム可能な駆動部と、
可動部材、ホイール及びギアをX軸に沿って角膜に向かって並進させる第3のプログラム可能な駆動部と、
第1のプログラム可能な駆動部を駆動して前記X軸およびY軸の両方で、前記ピボットの場所の位置を調節し、第3のプログラム可能な駆動部を駆動して、前記切開要素を前記角膜中の小さな初期切開を通って非切開角膜中に進行し、
第1及び第2のプログラム可能な駆動部を駆動して、前記小さな初期切開を拡大することなく前記角膜の内側に円形境界のポケットを切開するよう制御する切開案内ソフトウェアと、を備えるシステム。 - 前記フレームが吸着リングを備える、請求項1記載のシステム。
- 前記システムが、角膜用圧平板をさらに備える、請求項1に記載のシステム。
- 前記可動部材が直線状である、請求項1に記載のシステム。
- 前記切開要素が変形可能である、請求項1に記載のシステム。
