Puncture Needles for Medical Devices | Changfeng

Puncture needle is a fundamental minimally invasive medical device widely used for diagnostic aspiration, tissue biopsy, fluid drainage, drug delivery, and interventional therapy. Manufactured from medical‑grade stainless steel with precise bevel cutting, smooth surface, and consistent wall thickness, it ensures atraumatic penetration and reliable performance. It supports multiple clinical scenarios including ultrasound‑guided liver biopsy, thoracentesis, abdominocentesis, paracentesis, renal biopsy, thyroid biopsy, and vascular access. In a clinical case of suspected hepatic space‑occupying lesion, real‑time ultrasound‑guided puncture needle biopsy safely obtained valid tissue samples, enabling accurate pathological diagnosis and targeted treatment without open surgery. For patients with massive pleural effusion causing dyspnea, thoracentesis using this puncture needle rapidly drained excess fluid, relieved respiratory distress, and improved oxygenation. Jiangsu Changfeng Medical Industry Co., Ltd. provides single‑use sterile puncture needle with clear scale markings, color‑coded hubs, and secure Luer connectors to meet various depth and size requirements. Products are sterilized by ethylene oxide, pyrogen‑free, and individually packaged to ensure safety and convenience. Suitable for operating rooms, wards, interventional rooms, emergency departments, and outpatient clinics, they comply with international medical device standards.
