摘要：
A percutaneous nephrolithotomy (PCNL) needle (22) may include a cannula (269 including a shaft and a cannula hub (48) coupled to a proximal end of the cannula shaft. A depth guide (58) may be disposed on an outer surface of the cannula shaft. A stylet (24) may be disposable within the cannula lumen and may include a tapered point (32) at a distal end (28) of the stylet and a stylet hub (34) coupled to a proximal end (30) of the stylet that is configured to be releasably securable to the cannula hub. An adjustable depth stop 880, 180, 280, 380, 480, 580, 680, 780, 880) may be releasably securable to the cannula shaft at a desired position relative to the depth guide, the adjustable depth stop capable of being manipulated between an adjustment configuration in which the adjustable depth stop is moveable relative to the cannula shaft and a secured configuration in which the adjustable depth stop is secured relative to the cannula shaft.
