Puncture needle is essential for managing critical conditions by enabling rapid and minimally invasive intervention without traditional surgery. It delivers controlled access for aspiration, drainage, or injection in emergency and intensive care settings. In cardiac tamponade due to pericardial effusion, pericardiocentesis using this puncture needle rapidly aspirated excess fluid, relieved heart compression, and restored hemodynamic stability. For patients with severe acute cholangitis, percutaneous transhepatic biliary puncture and drainage quickly reduced bile duct pressure, controlled infection, and stabilized critically ill patients. The needle’s smooth insertion and stable structure reduce procedural risks even in unstable patients. Changfeng’s design emphasizes biocompatibility and mechanical safety, with reliable performance under high‑stress conditions.
