Bone access cannula

A bone access cannula is a sterile, single-use metal instrument used to create a pathway into bone for procedures like biopsies, marrow aspiration, or delivering therapeutic materials such as bone cement. Its sharp, hollow design allows precise insertion under imaging guidance, often paired with a stylet for safe handling, and is commonly used in orthopedic or interventional radiology settings.

These devices are typically classified as single-use and regulated under medical device standards that ensure sterility and precision. They may require imaging compatibility and are supplied pre-sterilized, often with clear instructions for use under controlled procedural conditions. Regulations vary by jurisdiction but generally emphasize safety and proper handling to prevent complications during bone access procedures.
