Devices, systems, and methods for navigating a biopsy tool to a target location and obtaining a tissue sample using the same
A system for performing a surgical procedure includes a bronchoscope, monitoring equipment coupled to the bronchoscope, a tracking system, a positioning assembly, and a biopsy tool. The biopsy tool includes an elongated flexible body extending from a proximal end to a distal end and a biopsy member formed on the distal end of the elongated flexible body. The biopsy member includes a tissue-receiving portion defining an opening including sharpened edges. The sharpened edges are disposed on the interior perimeter of the opening and are capable of cutting tissue. A biopsy tool is also provided.
