Abstract: Devices for guiding an instrument into a body of a patient, at a targeted point of entry and along an insertion path at a targeted insertion angle, are described herein, such as a guide for an access needle in a PCNL procedure for accessing the kidney to remove kidney stones. The devices include base component aligned with a point of entry, and a guide assembly which cooperates with the base component to allow an instrument to be aligned and fixed at various circumferential and vertical angles. The devices and methods allow a medical professional to accurately and stably guide an instrument at a targeted point and angle and to a desired depth, while minimizing the exposure to radiation used to image the insertion path.
