Automatic Biopsy Needles | Precision Diagnostic Tools

Automatic biopsy needle is a precision‑engineered single‑use medical device dedicated to minimally invasive tissue core sampling for pathological diagnosis, widely applied in ultrasound‑guided or CT‑guided percutaneous biopsy of soft tissue organs such as liver, kidney, prostate, breast, thyroid, lung, and lymph nodes. Jiangsu Changfeng Medical Industry Co., Ltd., founded in 1994 and formally established in 1999, integrates R&D, production, sales, and industrial services to develop high‑performance automatic biopsy needles that meet global clinical standards. Our products adopt medical‑grade 304 stainless steel and high‑strength biocompatible polymers, featuring ultra‑sharp triple‑bevel tips, smooth cannulas, optimized notch design, and spring‑actuated automatic firing mechanisms to ensure one‑handed operation, rapid penetration, consistent sampling, and minimal tissue trauma. Each needle undergoes strict lumen patency testing, sharpness verification, firing stability assessment, and terminal ethylene oxide sterilization to ensure safety and reliability. In clinical practice, automatic biopsy needles enable clinicians to obtain intact cylindrical tissue cores efficiently, reducing sample fragmentation and squeezing deformation, which significantly improves diagnostic accuracy and reduces the need for repeated punctures. In ultrasound‑guided breast biopsy, they support precise sampling of microcalcifications, nodules, and architectural distortions, helping distinguish benign lesions from malignant tumors and guiding subsequent treatment decisions. In prostate cancer screening, automatic biopsy needles provide targeted core sampling to detect early‑stage carcinoma with high sensitivity, supporting accurate grading and staging. In renal biopsy, they minimize the risk of bleeding and arteriovenous fistula while securing sufficient glomeruli for histopathological evaluation. In thyroid nodule assessment, they offer minimally invasive sampling with high diagnostic yield, avoiding unnecessary open surgery. With clear centimeter depth markings, safety locking systems, and color‑coded gauge indicators, our automatic biopsy needles enhance procedural control and reduce accidental firing. Changfeng’s dual production bases in Yangzhou Touqiao and Jiangdu Bridge, together with R&D centers in Hangzhou and Suzhou, support continuous product optimization and scalable manufacturing. The company adheres to a full‑cycle health management chain covering prevention, diagnosis, treatment, and rehabilitation, supplying high‑quality automatic biopsy needles to hospitals, clinics, and medical institutions worldwide. We also provide raw materials, components, and customized production services for medical device partners. Committed to the Healthy China strategy, we prioritize patient safety, clinical efficiency, and diagnostic accuracy to meet evolving global healthcare demands.
