What type of needle is used for biopsies and non-vascular access?

The Chiba needle is specifically designed for biopsies and non-vascular access, making it the correct choice in this context. It features a long, thin design with a sharp tip that allows for precise and minimally invasive sampling of tissue from various organs. The Chiba needle's unique design is particularly advantageous when targeting small lesions or structures, facilitating accurate tissue retrieval while minimizing damage to surrounding tissues.

This needle is often used in procedures such as percutaneous biopsies and aspirations, enabling physicians to obtain samples for analysis without the need for more extensive surgical interventions. Its effectiveness in accessing deep tissues and lesions makes it a vital tool in interventional radiology.

Other needle types, such as the trocar needle, green biopsy needle, and Franseen needle, serve different purposes or may not be as specialized for the non-vascular applications described. The trocar needle is typically associated with creating access for instruments, while green biopsy needles are often specific to certain biopsy procedures and may not be as universally versatile as the Chiba. The Franseen needle is generally utilized in particular types of tissue sampling but lacks the specific design characteristics that enhance the capability to target lesions accurately in various settings like the Chiba needle.
