Claims (1)
- 術者が把持するカッター本体部を持ち、眼球内の硝子体を切除する硝子体カッターにおいて、前記カッター本体部に取り付けられた外筒刃であって、円筒形状の側面に繋がる先端面が丸みを持つ曲面に形成されると共に該曲面の一部に硝子体を吸引する開口部が形成された外筒刃と、該外筒刃の軸中心にして外筒刃内で回転可能に保持される内筒刃であって、外筒刃の内径に略一致する円筒形状の側面に繋がる先端面が丸みを持つ曲面に形成されると共に該曲面の一部に硝子体を吸引する開口部が形成され、内筒刃の回転によって外筒刃の開口部と内筒刃の開口部とが重なり合う状態と、外筒刃の開口部が閉塞される状態と、を形成する内筒刃と、圧縮気体の供給状態を変えることにより前記内筒刃の軸方向に直進運動可能に前記カッター本体部に配置されたダイアフラムと、前記カッター本体部に配置され、前記ダイアフラムの直進運動を前記内筒刃の軸回りに正逆回転させる回転運動に変換して前記内筒刃に伝達する回転運動変換機構と、を備えることを特徴とする硝子体カッター。
