Zusammenfassung: | To provide a device which removes a kidney stone.SOLUTION: A nephroscope can include a body that is at least partially insertable into a kidney of a patient. An articulation controller on a grippable proximal portion of the body can adjust a position of a flexible distal portion of the body to locate a kidney stone when the body is inserted into the kidney of the patient. The articulation controller can optionally releasably lock the articulation of the flexible distal portion, to fixedly position the flexible distal portion at a specified location proximate the kidney stone. The distal end of the body can include an illuminator to illuminate the kidney stone, a camera to provide a video image of the illuminated kidney stone, an optical fiber to deliver laser light that ablate the kidney stone, and an irrigation lumen and a suction lumen to flush the kidney stone and remove kidney stone fragments.SELECTED DRAWING: Figure 1
【課題】腎結石を除去する装置を提供する。【解決手段】腎盂鏡が、患者の腎臓内に少なくとも部分的に挿入可能である本体を含んでもよい。本体が患者の腎臓内に挿入されているとき、本体の把持可能な近位部分の関節運動制御器が、本体の可撓性遠位部分の位置を調整して腎結石の位置を突き止めてもよい。関節運動制御器は、随意に、可撓性遠位部分の関節運動を解放可能に固定して、可撓性遠位部分を腎結石に近接した指定場所に固定して配置してもよい。本体の遠位端部は、腎結石を照明するための照明器と、照明された腎結石のビデオ画像を提供するためのカメラと、腎結石を削摩するレーザ光を供給する光ファイバと、腎結石を洗浄して腎結石破片を除去するための潅注管腔及び吸引管腔と、を含んでもよい。【選択図】図1 |
