Description
この出願は、本明細書に引用によってその全体が組み込まれている2019年9月9日出願の米国特許出願第16/565、403号及び2019年11月18日出願の米国特許出願第16/687、520号に対する優先権を主張するものである。
少なくとも一部の実施形態は、マルチポータル外科システムに関する。この外科システムを使用して、椎間板又は椎体が損傷した又は変位した患者を治療することができる。外科システムを使用して固定デバイス又は拡張可能な椎体間デバイスを埋め込んで椎体を離間させる、脊椎の安定性を回復させる、前弯矯正を提供する、又はその組合せなどを実行することができる。脊椎融合手順では、椎体間デバイスは、単独で又は骨、骨成長誘発材料、又は固定デバイス(例えば、椎弓根スクリューシステム、固定ロッドなど)などと組み合わせて使用することができる。内視鏡技術を使用して患者の脊椎を可視化し、例えば、脊椎(例えば、椎骨の間隔、椎骨の配置など)、組織(例えば、椎間軟骨円板の損傷又は変位した部分、神経圧迫の一因になる組織など)、器具及びインプラントを埋め込み前、埋め込み中、又は埋め込み後などに見ることなどができる。可視化は、外科手順の全体を通して医師を補助し、患者の転帰を改善することができる。
図1は、本発明の開示の実施形態によりヒト被験者の脊椎に沿って位置決めされた脊椎外科システム100(「システム100」)の側面図である。システム100は、器具アセンブリ130と可視化アセンブリ160を含むことができる。器具アセンブリ130は、外科手順の少なくとも一部分を実行するのに使用することができ、一方で可視化アセンブリ160は、可視化を提供する。器具アセンブリ130は、器具110とカニューレ120を含むことができる。ポートを使用して器具アセンブリ130及び/又は可視化アセンブリ160の挿入を容易にすることができる。例えば、可視化アセンブリ160は、内視鏡ポートに位置決めすることができ、器具アセンブリ130は、器具ポートに位置決めすることができる。
図13は、図1~11、14~16、及び18~19に関連して説明した構成要素を含む手術キット1200の上面図である。キット1200は、カニューレ120、150及びポートのセット1210を含むことができる。医師は、ポータル部位の場所と利用する器具とに基づいて適切なポートを選択することができる。例示的実施形態では、セット1210は、4つのポートを含む。より多い又は少ない数のポートを提供することができ、かつ同じか又は異なるサイズとすることができる。キット1200は、カニューレ(例えば、カニューレ120、150、1400)を互いに結合するためのコネクタ(例えば、剛性コネクタ)を含むことができる。カニューレは、椎体間融合デバイスを椎間埋め込み部位で拡張させる前に互いに結合することができる。
