Puncture Needle Set with Trocar and Chiba Tip Options
This Puncture Needle Set provides two distinct needle-tip technologies – Trocar and Chiba – allowing clinicians to select the optimal access strategy based on procedure type, tissue characteristics, and safety requirements. Designed with clear color-coded identification and enhanced tip geometries, the set ensures precise, controlled percutaneous access for diagnostic and interventional procedures.
Dual-Tip Technology: Select the Right Tool for the Case
Trocar-Tip Needle – For Controlled, Guided Access
Non-cutting, blunt-cannula tip guides the wire without shearing or damaging the coil
Excellent direct-advancement capability maintains needle trajectory without deviation
No specific tip orientation required during insertion – simplifies handling and reduces wire twisting
Ideal for: procedures requiring precise wire guidance, repeated needle passes, or when wire integrity is critical
Chiba-Tip Needle – For Sharp, Delicate Penetration
Ultra-sharp beveled tip facilitates smooth tissue penetration with minimal force
Enhanced vessel-avoidance capability due to controlled, sharp entry
Requires tip-orientation awareness during insertion to prevent wire-tip contact
Ideal for: fine-needle aspiration, delicate tissue sampling, accessing small or mobile targets
Color-Coded Gauge System – Instant Visual Identification
