Abstract

Methods, systems, and devices for marking the location of a biopsy are disclosed, including loading a navigation plan into a navigation system with the navigation plan including a CT volume generated from a plurality of CT images, inserting a probe into a patient's airways with the probe including a location sensor in operative communication with the navigation system, registering a sensed location of the probe with the CT volume of the navigation plan, selecting a target in the navigation plan, navigating the probe and location sensor to the target, storing a position of the location sensor in the navigation system as a biopsy location, and performing a biopsy at the stored biopsy location.

Description

technical field [0001] The present disclosure relates to biopsy location labeling and devices, systems and methods for labeling biopsy locations on a bronchial tree model. Background technique [0002] A common device used to examine a patient's airway is a bronchoscope. Typically, a bronchoscope is inserted into the patient's airway through the patient's nose or mouth, extending into the patient's lungs. A typical bronchoscope includes an elongated flexible tube with an illumination assembly for illuminating the area distal to the bronchoscope tip, an imaging assembly for providing video images from the bronchoscope tip, and a working channel , instruments such as diagnostic instruments (eg, biopsy tools), therapeutic instruments, etc. can be inserted through the working channel. [0003] However, bronchoscopes are limited in how far they can be advanced into the airway due to their size. If the bronchoscope is too large to reach target locations deep in the lungs, clini...
