Ultra-Long & Thin Design, Precise Puncture

The needle features a long, slender shaft with high straightness (length-to-diameter ratio up to 10:1 or higher). The front tip is precisely ground into a sharp bevel, minimizing penetration resistance and tissue damage while ensuring strong穿透力 (penetration) through deep tissues (fascia, muscle).

Precision Manufacturing, Consistent Performance

Processed via CNC turning, ultrasonic cleaning, and electrolytic polishing, the inner wall is ultra-smooth (Ra≤0.4μm) for unobstructed fluid/device passage. Tip angle and outer diameter tolerance are strictly controlled within ±0.01mm, ensuring batch-to-batch consistency.

Side Port Design (Optional), Efficient Drainage/Perfusion

Some models feature side ports on the shaft, enabling efficient drainage (abscess, effusion) or drug perfusion without tip clogging, enhancing procedural efficiency.

Ergonomic Design, Easy Operation

The rear end is available with a smooth taper or standard Luer lock, facilitating quick connection with syringes, guidewires, or catheters. The smooth surface ensures no sticking during handling, suitable for fine operations.

Compliant & Traceable Quality

Certified under ISO 13485 medical quality management system, with full traceability to meet global market access standards (FDA, CE, NMPA), supporting hospitals’ compliance procurement.
