Product Description
The EVT YL-D21Z-011 puncture needle set provides selectable Trocar and Chiba tip technologies in gauges 18G, 21G and 22G. Color-coded hubs enable immediate gauge identification and the set is available in fluoroscopy-ready and echogenic variants to support precise percutaneous access for diagnostic and interventional procedures.

Dual-Tip Technology
Trocar-Tip Needle – For controlled, guided access

• Blunt, non-cutting cannula tip guides guidewire without shearing or damaging the coil
• Reliable direct-advancement maintains needle trajectory with minimal deviation
• No specific tip orientation required during insertion, simplifying handling
• Suitable for repeated passes or procedures where guidewire integrity is critical

Chiba-Tip Needle – For sharp, delicate penetration

• Ultra-sharp beveled tip enables smooth tissue penetration with minimal force
• Controlled sharp entry helps avoid vessels and reduce collateral tissue trauma
• Requires awareness of tip orientation during insertion to avoid wire-tip contact
• Suitable for fine-needle aspiration, delicate sampling and small/mobile targets

Color-Coded Gauge System – Instant Visual Identification
Color | Gauge | Application
Black hub | 22G | Fine-caliber access for cytology or pediatric use
Green hub | 21G | Balanced access for diagnostic aspiration or contrast injection
Pink hub | 18G | Larger lumen for biopsy, drainage or viscous fluid aspiration

Clinical & Safety Advantages

• Procedure-matched tip selection optimizes guidance (Trocar) or penetration (Chiba)
• Trocar blunt-tip design reduces risk of guidewire damage
• Chiba sharp-tip allows precise vessel avoidance and lower tissue disruption
• Color-coded hubs speed recognition and reduce selection errors during procedures

Typical Applications

• Fine-needle aspiration (FNA) and biopsy
• Percutaneous cholangiography (PTC) and biliary drainage (PTCD)
• Nephrostomy access and renal biopsy
• Abscess or fluid collection aspiration
• Vascular access and contrast injection
• Pediatric and delicate-tissue interventions
