Description
本発明は、血管などの脈管のサイズ及び/又は辺縁を決定するためのシステム及び方法、特に、脈動成分を含むセンサアレイに伝送される光を使用するシステム及び方法に関する。
本発明の一態様によれば、外科用器具の作業端部に近接する領域内の脈管のサイズを決定するために使用される外科用システムは、外科用器具の作業端部に配置される少なくとも1つの発光体と、少なくとも1つの発光体の反対側の外科用器具の作業端部に配置される光センサアレイであって、当該光センサアレイは少なくとも1列の光センサを備え、光センサの列内の個々の光センサは、第1脈動成分と第2非脈動成分とを含む信号を生成するように構成された光センサアレイとを備える。システムはまた、光センサアレイに連結された制御装置を備え、当該制御装置は、第1脈動成分を第2非脈動成分から分離するためのスプリッタと、光センサの列内の個々の光センサで脈動成分及び非脈動成分のスケールを決定し、脈動成分の第1ピークスケール及び第2ピークスケールを決定し、脈動成分の第1ピークスケール及び第2ピークスケールに基づいて脈管の静止外径を決定するための分析器とを備える。
本発明の一実施形態に係る外科用システムは、少なくとも1つの発光体と少なくとも1つの光センサと制御装置とを備える。システムはまた、外科用器具も同様に備えてもよい。
方程式(2)及び(3)を組み合わせると、次式(方程式4)になる。
方程式4によれば、組織についての分散又はAC RMSは、経時的にほぼ一定のままであろう。しかしながら、これは血管がジョー部の間にある場合にはそうではないだろう(α(t)≠α)。血管について、信号は正弦波となり、分散/AC RMSはその実際値(約1時間間隔)で飽和する前に急激に増加する。そこで、v(t)の値をみると、1≦t≦uであり、ここで2≦uTであり、Tは信号又は心拍数の時間間隔である。
次いで、この比を閾値と比較して組織と血管とを区別することができる。
