Comprehensive Technical Overview
Our custom biopsy needles are engineered for unmatched clinical precision, balancing the delicate requirements of patient comfort with the uncompromising need for high-quality tissue acquisition. Designed for seamless integration into diverse diagnostic procedures, every needle represents the pinnacle of medical micro-manufacturing.
Advanced Tip Geometry: Available in Chiba, Franseen, Menghini, and custom bevel designs, precision-ground to minimize insertion force, reduce tissue trauma, and prevent deflection.
Optimal Sample Yield: Ultra-thin wall technology maximizes the inner diameter (ID) while maintaining rigid outer diameter (OD) integrity, ensuring intact, non-fragmented core samples.
Enhanced Echogenicity: State-of-the-art echogenic texturing (laser or mechanical etching) applied precisely where you need it, delivering crystal-clear visibility under ultrasound guidance.
Ergonomic & Mechanical Integration: Fully customizable hub designs (luer lock, color-coded, or proprietary interfaces) and flawless compatibility with automated or semi-automated biopsy guns.
Why Choose LIJ Med Tube?

Unrivaled Micro-Tubing Expertise: Leveraging decades of precision drawing and fabrication experience, we achieve tight tolerances that standard manufacturers simply cannot match.
End-to-End Customization: From custom stylet profiles and notch geometries to proprietary surface coatings (hydrophilic or PTFE), we build exactly to your blueprints.
Rigorous Quality Assurance: Manufactured in ISO-certified cleanrooms, our needles undergo 100% visual and dimensional inspection to guarantee zero-defect performance in critical clinical settings.
Scalable Prototyping to Mass Production: We support your journey from early-stage R&D samples to high-volume commercial supply with agile lead times and robust regulatory compliance.
Target Applications & Clinical Fields
Our custom biopsy needles are designed to meet the rigorous demands of modern interventional radiology, oncology, and surgery. We provide specialized component solutions for a wide range of diagnostic procedures:
Oncology & Tumor Diagnostics: Precision core needles for breast, lung, liver, prostate, and kidney mass sampling, ensuring high-quality tissue architecture for histopathology.
Soft Tissue & Deep-Seated Biopsies: Engineered with advanced echogenicity for deep-tissue mapping under ultrasound, CT, or MRI guidance.
Hematology (Bone Marrow Biopsy): High-strength, reinforced needle configurations designed to penetrate cortical bone smoothly while capturing pristine marrow architectures.
Endoscopic Ultrasound-Guided Biopsy (EUS-FNA/FNB): Ultra-flexible, high-performance needle components tailored for gastrointestinal and pancreaticobiliary sampling through flexible endoscopes.
Aspiration & Fluid Sampling: Custom Chiba and spinal-tip geometries optimized for fine-needle aspiration (FNA) of cysts, nodules, and fluid collections.
