The 12/14 Fr Ureteral Access Sheath (UAS) represents a critical shift in RIRS (Retrograde Intrarenal Surgery). As the industry moves toward "dusting" techniques, the requirement for high-flow irrigation and vacuum-assisted debris extraction has become paramount. Our engineering roadmap focuses on two core pillars: Hydrophilic coating persistence and kink-resistance under high suction pressure.
Leveraging advanced manufacturing clusters in Jiangxi, our facility integrates automated coil-winding and precision laser-welding processes. This ensures every 12/14 Fr sheath maintains a consistent internal diameter (ID) while minimizing the outer profile, ensuring minimal ureteral trauma.
The 12/14 Fr size provides the optimal balance between instrument maneuverability and the necessity for active suction, particularly when treating large stone burdens.
