*Abstract

Design Extracts More Tissue with Less Force, Reduction of Pain, and Reduced Damage to Biopsy Samples

This coaxial biopsy needle design can extract more tissue with less suction force and less damage in both fine needle aspiration and core needle biopsy procedures. Each year globally, about 14 million people learn they have cancer, and 8 million people die from the disease, according to the Centers for Disease Control and Prevention. When doctors notice unusual lesions, tumors, or masses, they can collect samples to check for cancer and other diseases. The market for biopsy tools will be worth $1.9 billion in 2018. Challenges in developing biopsy needle designs include improving cost-effectiveness, reducing the discomfort experienced by the patient, and reducing damage to the extracted tissue. University of Florida researchers have developed a coaxial biopsy needle -- an inner stylet positioned within an external needle -- that can extract a bigger sample while using a smaller needle diameter, which can reduce the discomfort felt by the patient.

Application

Coaxial design for more effective fine needle aspiration and core needle biopsy cancer screening

Advantages

• Extracts sample using smaller needle diameter, reducing patient discomfort
• Results in bigger, less-damaged extracted samples, making biopsy more accurate and cost-effective

Technology

This biopsy needle uses a cylindrical coaxial design to extract tissue samples from patients more effectively than available needle designs. The design includes an inner stylet positioned within an external needle affixed to the outer casing of a syringe Doctors can insert the needle into a target site with less force and more accuracy than a traditional needle, knowing that they will see less deflection and friction between the tissue and surface. Doctors can complete fine needle aspirations or core needle biopsies with less pain for patients, reduced damage to tissue samples, and more accuracy in cancer screen procedures, leading to cost savings.
