Puncture Needles for Medical Devices | Changfeng

Advanced materials and precision manufacturing enhance puncture needle performance for complex interventional procedures. High‑strength stainless steel resists bending during deep tissue insertion, while precision grinding ensures consistent sharpness. The needle performs reliably in prolonged procedures such as multiple‑site tumor biopsies or prolonged drainage. In percutaneous biliary drainage for malignant obstruction, it maintained stable access for long‑term palliation. Changfeng’s material selection ensures compatibility with CT, MRI, and ultrasound environments. Products are tested for biocompatibility, cytotoxicity, and sensitization. R&D bases in Hangzhou and Suzhou drive material and design innovation. For high‑complexity medical centers or academic hospitals, we provide premium‑grade configurations.
