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

Clinical & Safety Advantages
- Procedure-matched tip selection – optimize for guidance (Trocar) or penetration (Chiba)
- Reduced wire damage risk – Trocar flat-end design protects guidewire integrity
- Lower bleeding risk – Chiba sharp-tip allows precise vessel avoidance
- Quick gauge recognition – color-coded hubs streamline workflow and reduce errors
Typical Applications
