Pure Iron Coils for Surgical Instruments | Beilun Metal
High-Precision, Bio-Safe Iron Coils for Minimally Invasive and Robotic Surgical Tools
Product Overview
Beilun Metal's surgical-grade Pure Iron Coils are engineered to empower next-generation surgical instruments with micron-level actuation accuracy and uncompromising biocompatibility. Featuring 99.99%+ purity and ultra-smooth surfaces (Ra ≤0.05μm), our coils meet ISO 7153-1 and ASTM F3184 standards for materials in contact with human tissue, ideal for laparoscopic tools, electrosurgical devices, and AI-driven robotic systems.
Key Features & Benefits
Surgical-Grade Material Safety
Iron Purity: ≥99.99%
Critical Contaminant Control: Chromium (≤0.001%), Nickel (≤0.0008%), Cytotoxic Elements (Cu/Pb <1ppm)
Compliance: ISO 10993-5 (Non-cytotoxic), USP Class VI (Plastic/Elastomer Compatibility).
Nanoscale Precision for Micro-Instruments
Thickness: 0.01mm–0.5mm (ultra-thin for micro-forceps & articulating joints)
Tolerance: ±0.002mm (ensures seamless integration with piezoelectric actuators)
Edge Quality: Laser-microfused edges prevent particulate shedding during surgery.
Sterilization & Corrosion Resistance
Autoclave Cycles: 1,000+ cycles at 135°C without oxidation (per AAMI ST79)
Chemical Resistance: Withstands hydrogen peroxide plasma, peracetic acid, and alcohol immersion.
Surface Options: Electropolished (Ra ≤0.05μm) or diamond-like carbon (DLC) coating for wear resistance.
Zero Magnetic Interference
Residual Magnetism: <0.01 mT (prevents interference with intraoperative imaging/navigation)
Core Loss: <0.5 W/kg (at 0.3T, 100Hz) for precise haptic feedback in robotic systems.
Applications in Surgical Instruments
Robotic Surgery: Forceps actuation cores, da Vinci®-style wrist joints.
Electrosurgery: Bipolar forceps electrodes, RF ablation coil drivers.
Endoscopy: Articulating camera positioners, biopsy channel shutters.
Orthopedic Tools: Smart drill torque sensors, bone cement mixing actuators.

FAQ
Q: Are your coils MRI-safe for hybrid OR environments?
A: Yes! Our non-ferritic structure and <0.01 mT remanence meet ASTM F2503 MRI safety standards.
Q: Can you provide coils pre-coated with Parylene for insulation?
A: Yes, Parylene C/N coatings (2–25μm) applied in ISO Class 7 cleanrooms.
Q: How do you prevent galvanic corrosion in saline environments?
A: Optional titanium nitride (TiN) coating reduces galvanic potential to <0.1V vs. stainless steel.
Q: MOQ for prototype trials?
A: R&D batches as low as 5kg with full biocompatibility documentation.
