- 眼科手術の際の一時的に眼球の外膜に装着させて眼球の内外を導通させるための眼球装着管であって、
管状に形成され、前記外膜への装着時には前記外膜に刺さった状態となる管状部と、
前記管状部の基端側に位置して、前記管状部の外径よりも大きい外径を有し、前記外膜への装着時には前記外膜の外側に露出した状態となる大径部とを備え、
前記大径部の、前記管状部の中心軸線に平行な方向における前記管状部の側の端部は、側面視で見て、前記中心軸線に直角な方向における一端側と他端側との間で前記平行な方向に高低差を有する形状に形成され、
前記端部の全体が前記中心軸線に対して傾斜した面に形成され、
前記大径部の、前記平行な方向における前記端部の反対側の端部は、前記中心軸線に対して直角な面に形成される、
眼球装着管。 - 前記大径部は、前記反対側の端部に形成される開口から液体が流出するのを抑制する弁を有する請求項1に記載の眼球装着管。
- 前記傾斜した面は平面である請求項1又は2に記載の眼球装着管。
- 前記傾斜した面は凹曲面であり、
前記中心軸線を面内に含んだ平面で前記眼球装着管を切った、前記側面視と同じ方向から見た断面でみて、前記凹曲面は、前記中心軸線に直角な方向における一端側から他端側に向かうにつれて徐々に前記管状部の先端の方に変位するとともに、前記中心軸線に対して斜めの曲線を描くように形成され、
前記中心軸線を面内に含んだ、前記断面に直角な平面で前記眼球装着管を切った断面でみて、前記凹曲面が描く断面線は、前記断面線における一方の端部から前記中心軸線の方に近づくにしたがって徐々に前記反対側の端部側に曲線状に変位し、前記中心軸線の側から前記断面線の他方の端部の方に近づくにしたがって徐々に前記管状部の先端側に曲線状に変位し、前記断面線の両端部は前記中心軸線が延びた方向における同じ位置に設けられる請求項1又は2に記載の眼球装着管。
