Biopsy Needle: Precision Tissue Sampling for Definitive Diagnosis.
Biopsy Needle Clinical Purpose
Our biopsy needle delivers unparalleled accuracy in obtaining high-yield tissue cores for pathological analysis. Designed for ultrasound, CT, or MRI-guided procedures, it enables reliable sampling of lesions in organs including liver, breast, prostate, and lung—critical for cancer diagnosis, staging, and treatment planning.
Key Advantages
Optimal Sample Integrity
– Twin-bevel cutting edge: Ultra-sharp 14° tip preserves tissue architecture with minimal crushing artifact.
– Adjustable throw length (10–25mm): Customizable penetration depth for precise lesion targeting.
Enhanced Safety & Control
– Echogenic distal notch: Real-time ultrasound visibility with 360° rotational alignment.
– One-handed firing mechanism: Smooth trigger operation reduces hand tremor risks.
Procedural Efficiency
– Core sample retrieval >98% success rate (per Radiology 2024 study data).
– Integrated vacuum assist maintains sample cohesion during withdrawal.
Advanced Material Engineering
– Cannula: Electropolished 304VM stainless steel (wall thickness: 0.13mm) for superior flexural strength.
– Trocar: Tungsten-carbide reinforced tip (HRC 62±2) retains sharpness through dense tissue.
– Coating: Hydrophilic polymer (contact angle: 12°) reduces insertion force by 50%.
Applications
– Core needle biopsy (CNB) of tumors
– Breast biopsy under stereotactic guidance
– Transrectal prostate sampling
– Lung nodule FNA/FNB procedures
