Description
本願は、2018年2月9日に出願された同時係属中の米国特許出願第15/892,833号の一部継続出願であり、本願において、上記米国特許出願の全体を引用して援用する。上記米国特許出願は、2017年10月18日に出願された米国仮特許出願第62/574,136号に基づく優先権を主張するものであり、本願において、上記米国仮特許出願の全体を引用して援用する。
ポジショナのいくつかの実施形態は光源を備え、その光源は、複合マイクロカニューレの光ガイド内へ光を発し、且つ、第2の光ガイドが設けられている場合にトロカールに連結された第2の光ガイド内へもオプションで光を発するように配置される。ポジショナは、マイクロカニューレの眼内への進入点を乱すことなく、複合マイクロカニューレの正確な前進および/または後退を実現させることができ、それによって、治療処置の完了までに必要な時間が短縮され、眼の組織の損傷のリスクが低減する。
2と、複合マイクロカニューレの端部から放出された光614とは、短い波線で示されている。トロカールおよび複合マイクロカニューレの位置を示す輝点を観察するために、ゴニオプリズムを用いることができる。
