A Revisit into Blunt-Tip Coaxial Introducer Technique

Biopsy procedures, especially those guided by computed tomography, pose significant challenges when vital structures are present along the needle path. The advent of the blunt-tip coaxial introducer has improved the safety and efficacy of these procedures by facilitating controlled needle advancement while minimizing the risk of injury to critical structures. Initially introduced for procedures such as nephrostomy, biliary drainage, and abscess drainage, the blunt-tip coaxial introducer has proven to be an effective tool in navigating complex anatomical regions.
