前記窪み部分は、前記中心本体軸を包有する平面において断面で見たときに正弦形状を有する、請求項11に記載の水晶体乳化吸引針。 - 前記閉塞低減手段は、前記針本体の複数の周期的な円周窪み部分である、請求項11に記載の水晶体乳化吸引針。
- 前記閉塞低減手段は、前記中心本体軸に対して直角な平面に対して角度付けられた、前記針本体の複数の周期的な窪み部分である、請求項11に記載の水晶体乳化吸引針。
- 前記閉塞低減手段は、前記吸引通路内に延在する少なくとも1つの捻れインサートである、請求項1に記載の水晶体乳化吸引針。
- 前記閉塞低減手段は、前記吸引通路内に延在する一対の捻れインサートである、請求項15に記載の水晶体乳化吸引針。
- 前記閉塞低減手段は、前記吸引通路内に延在する複数の径方向に延在するブレードである、請求項1に記載の水晶体乳化吸引針。
- 水晶体乳化吸引を行う方法であって、
請求項1に記載の水晶体乳化吸引針を得ることと、
前記水晶体乳化吸引針の前記近位端部に振動性ハンドピースを組み付けることと、
前記ハンドピースによって前記針に振動を与えて、眼内の組織を乳化することと、
