Abstract
Description
典型的なレーザの出力パラメータは、繰り返し周波数(秒あたりのレーザパルス数)、パルスあたりのエネルギー、およびパルス幅である。
上述の技術は、必要な変更を加えて、バスケット砕石デバイスまたは超音波プローブなどの上記の他のタイプの体内砕石術に適用することが可能である。例えば、石および破片のサイズが、レーザの照準ビームを使用して判定することができない一方で、それらのサイズは、砕石器プローブの既知のサイズまたは画像認識プログラムによる画像処理を利用して推定され得る。石破片の検出により、砕石モジュールは、石に対して印加される破壊エネルギーを変更することが可能となる。内視鏡から結石までの距離を変更することは、超弾動技術においてレーザを用いる場合よりも高い影響をもたらす場合があり、オペレータによりある程度まで制御され得る。
次に図10を参照すると、この図は、本発明の一実施形態による体内砕石術の一方法の流れ図である。処置は、初めのステップ86にて開始される。被検者が、内視鏡を挿管される。これは、典型的には、上述のような尿管鏡または腎臓鏡であり、結石と接触状態にまたは結石の近傍に配置される。内視鏡は、上記のような光学撮像能力およびエネルギー送達システムを備える。次に、ステップ88で、結石の初期光学画像が取得される。
