0.4mm Pediatric Puncture Tube – Ultra-Fine Precision Tube for Pediatric Minimally Invasive Procedures
The 0.4mm Pediatric Puncture Tube is an ultra-fine, high-precision medical tube designed for puncture and biopsy applications in pediatric patients. Crafted from medical-grade SUS304 stainless steel, this tube provides exceptional strength, flexibility, and biocompatibility, ensuring safe and precise access to anatomical sites in minimally invasive interventions. Produced using advanced laser micromachining, it features burr-free surfaces and exact dimensions, enabling seamless integration into puncture devices while maintaining corrosion resistance and sterility.
Key Features:
- Ultra-High Precision: Achieves cutting seam widths of 15–30μm and accuracy of ≤±10μm for burr-free, smooth surfaces.
- Superior Durability: Offers high tensile strength and corrosion resistance for reliable performance in physiological environments.
- Biocompatibility: Hypoallergenic material minimizes tissue reaction, ideal for sensitive pediatric applications.
- Flexibility: Supports variable bending without kinking, enhancing maneuverability in micro-puncture tools.
- Efficient Integration: Compatible with various clamping systems and cutting methods for rapid assembly.
- Sterility Maintenance: Smooth finish reduces contamination risks and supports sterilization processes.
Certification and Standards:
The 0.4mm Pediatric Puncture Tube complies with ISO 13485 quality management standards for medical devices and adheres to biocompatibility requirements under ISO 10993.
Stainless Steel SUS304:
Medical-grade SUS304 stainless steel (austenitic chromium-nickel alloy), offering excellent corrosion resistance and mechanical properties.
- Biocompatibility: Low risk of allergic reactions or toxicity, ideal for direct tissue contact in medical procedures.
- Mechanical Properties: High tensile strength (approximately 505 MPa) and elongation (up to 40%), providing flexibility without brittleness.
- Surface Finish: Laser-machined for smooth, burr-free edges, reducing the potential for tissue trauma or contamination.
- Thermal Stability: Maintains integrity across a wide temperature range, suitable for sterilization processes like autoclaving.
Nickel-Titanium alloy:
Nitinol (NiTi), a nickel-titanium alloy, is renowned for its superelasticity and shape memory, making it a game-changer in medical applications. With a tensile strength of up to 1200 MPa and elastic modulus of 40–75 GPa, nitinol excels in demanding environments.
Cobalt-chrome alloy:
Cobalt-chrome (CoCr), an alloy of cobalt and chromium often enhanced with molybdenum, is prized for its exceptional strength, corrosion resistance, and biocompatibility. With tensile strength ranging from 800–1500 MPa and hardness of 300–550 HV, CoCr is a cornerstone in medical technology. Popular grades like L605 (Co-Cr-W-Ni) and MP35N (Co-Cr-Ni-Mo) elevate its performance.
