Claims (6)
- 硝子体手術の際等に眼球内に挿入される細管状もしくは針状の挿入部材を備えた眼科用手術器具であって、
前記挿入部材の外周に、該挿入部材の眼外に位置する部分の剛性を強化する補強スリーブが嵌挿されると共に、該補強スリーブが、前記挿入部材の眼内への挿入量に応じて剛性を強化する長さを変化させることができるように、前記挿入部材の軸方向に移動自在に設けられ、
前記挿入部材の基端側に一体に設けられたブロックに、前記挿入部材の軸方向に沿ってスリーブ収納孔が形成され、該スリーブ収納孔の先端壁に、前記スリーブ収納孔の内径より径小な摺動孔が形成され、
前記スリーブ収納孔の内部に、前記補強スリーブをその先端方向に向けて付勢する圧縮バネが収容され、
一方、前記補強スリーブには、前記挿入部材の外周に嵌挿された細長のスリーブ本体部の基端側に、該スリーブ本体部よりも径大なスライダ部が一体的に設けられ、
前記補強スリーブが、前記スライダ部を、前記スリーブ収納孔の内部に該スリーブ収納孔の内周円筒壁に対して摺動自在となるよう挿入し、且つ、前記スリーブ本体部を、前記摺動孔に摺動自在に貫通させることにより、前記摺動孔の内周とスリーブ本体部の外周との摺動接触部と、前記スリーブ収納孔の内周円筒壁と前記スライダ部の外周との摺動接触部の2箇所を支持部とした状態で、前記ブロックに前記挿入部材の軸方向に移動自在に支持されており、
前記摺動孔の内周とスリーブ本体部の外周との摺動接触部が断面点接触になっており、
前記圧縮バネの付勢力に抗して前記補強スリーブを前記挿入部材の軸方向に移動させた場合に、前記摺動孔の内周とスリーブ本体部の外周との摺動接触部と、前記スリーブ収納孔の内周円筒壁と前記スライダ部の外周との摺動接触部との間の距離が増加するように構成され、
しかも、前記スリーブ収納孔の内周円筒壁に対する前記スライダ部の外周の接触面が、前記スリーブ収納孔の内周円筒壁の曲率よりも大きい曲率を有する凸曲面で構成されていることを特徴とする眼科用手術器具。 - 前記凸曲面が、前記スリーブ収納孔の内周円筒壁の直径よりも僅かに小さい直径の球面で構成されていることを特徴とする請求項1に記載の眼科用手術器具。
- 前記球面に、前記スリーブ収納孔の内周円筒壁に対する接触面積を減らすための複数の切欠が設けられていることを特徴とする請求項2に記載の眼科用手術器具。
- 前記スリーブ収納孔の内周円筒壁に対向する前記スライダ部の外周部に円周方向に間隔をおいて、前記スリーブ収納孔の内周円筒壁に接触可能な複数の小球が定位置に保持された状態で転動自在に設けられており、前記各小球の外周球面が前記凸曲面に相当することを特徴とする請求項1に記載の眼科用手術器具。
- 前記小球が、前記スリーブ収納孔の軸方向に間隔をおいて複列に配列されていることを特徴とする請求項4に記載の眼科用手術器具。
- 前記スリーブ収納孔の先端壁に形成された前記摺動孔の内周縁の断面形状が、前記スリーブ本体部の外周に対する接触面積を減らすために略半円状に形成されていることを特徴とする請求項1〜5のいずれか1項に記載の眼科用手術器具。
