View Product SpecsTransitioning from passive fluid overflow to dynamic negative-pressure evacuation in Retrograde Intrarenal Surgery (RIRS).
The clinical paradigm of Flexible Ureteroscopy (fURS) has undergone a fundamental transformation over the last decade. Conventional ureteral access sheaths (UAS) have long served as conduits to facilitate flexible scope passage, shield the delicate ureteral urothelium from repeated friction, and allow passive drainage of irrigation fluid. However, passive reflux mechanisms have severe hemodynamic constraints. In modern high-power holmium laser and Thulium fiber laser (TFL) lithotripsy, continuous saline irrigation is required to preserve optical clarity and prevent thermal tissue injury. Under continuous forced irrigation, Intrarenal Pressure (IRP) routinely surges beyond physiological thresholds, frequently exceeding 40 to 60 mmHg.
Sustained intrarenal pelvic pressure exceeding 30 mmHg breaches the protective pyelovenous and pyelolymphatic barriers. This clinical phenomenon induces pyelovenous backflow, causing retrograde systemic infusion of bacterial endotoxins, infectious pelvic micro-stones, and irrigation contaminants. Clinically, this leads to immediate postoperative complications including systemic inflammatory response syndrome (SIRS), high-grade septic pyelonephritis, subcapsular renal hematoma, and perirenal fluid extravasation. The Suction-Assisted Ureteral Access Sheath (Vaccum-UAS) redefines endourological safety by integrating an active negative-pressure evacuation channel that continuously evacuates fluid, stone retropulsion dust, and mucosal debris while keeping IRP securely below critical hydrostatic safety ceilings.
Continuous closed-loop or modulated aspiration balances inflows from pressurized automated irrigation systems, keeping pyelocaliceal pressures safely below the pyelovenous backflow inflection threshold (25–30 mmHg).
Replaces the time-consuming and traumatic manual stone extraction with nitinol baskets. Micronized fragments and laser vapor clouds are rapidly drawn through the annular sheath lumen under regulated vacuum.
Engineered with an oblique 45-degree or angled luer lock suction port and dual-gasket seal that accommodates standard flexible ureteroscopes while eliminating fluid leakage around the working channel entry.
How state-of-the-art engineering hubs like Jiangxi ZhuoRuiHua Medical Instrument Co., Ltd. are transforming medical consumable contracts for multinational distributors.
In the volatile medical device landscape, global healthcare systems demand strict dual-sourcing resilience, complete raw-material lot traceability, and uncompromising regulatory alignment. As an authoritative ODM contract manufacturer, Jiangxi ZhuoRuiHua Medical Instrument Co., Ltd. (ZRH Med) combines vertically integrated polymer extrusion, in-house nitinol coil braiding, cleanroom injection molding, and ISO 11135 EO sterilization cycles under a single enterprise roof in Jiangxi, China.
By automating the multi-stage assembly of micro-composite tubing, our Smart Factory 4.0 architecture eliminates manual variation in wall thickness, optimizes coil-pitch consistency, and guarantees kink-free flexibility. Global medical device distributors and private-label OEMs benefit from significant supply chain consolidation—sourcing their full clinical pathway across GI biopsy forceps, rotatable hemostasis clips, ERCP cannulation devices, and advanced suction access sheaths without cross-vendor interface friction.
Ultra-thin medical PTFE inner liner provides frictionless scope advancement. SUS304 high-tensile braided/coiled mesh prevents lumen collapse under -60 kPa suction, clad in high-recovery polyether block amide (PEBAX).
Proprietary photo-crosslinked hydrophilic chemistry applied along the insertion sheath yields a durable, ultra-slick surface with a kinetic friction coefficient <0.02, mitigating ureteral mucosal trauma and spasm.
Class 100,000 (ISO Class 7) precision injection tooling hubs with automated vision systems (AOI) verifying tip taper, atraumatic transitions, and gold/platinum radiopaque marker ring placement to within ±0.01mm.
Full technical documentation packages supporting EU MDR (2017/745), US FDA 510(k), and Latin American/Middle Eastern national tenders. Complete biocompatibility data per ISO 10993 and sterilization validation per ISO 11135.

Inner / Outer diameters customized for pediatric, adult, and dilated ureteral pathways: 10/12 Fr, 11/13 Fr, 12/14 Fr, and high-volume 14/16 Fr for bulk clearance.
Standardized lengths of 20cm, 28cm, 35cm, 45cm, and 55cm. Dilator taper angles calibrated for smooth passage across the ureterovesical junction (UVJ).
Medical Tyvek pouches with double-sterile barrier protection, customized thermoformed trays, IFU multi-language typesetting, and private brand carton design.
Real-world procedural performance in demanding high-volume endourology departments.
Struvite and high-bioburden stones carry immense sepsis risks during lithotripsy. Suction access sheaths ensure continuous evacuation of cloudy fluid, bacteria, and particulate micro-debris, keeping urine clear and protecting the patient from sepsis.
High-frequency laser settings create dense visual dust storms. The negative-pressure suction port rapidly clears laser debris clouds, giving surgeons uninterrupted optical visualization and preventing stone retropulsion into unreachable calyces.
By preventing intrarenal barotrauma and pyelocaliceal extravasation, postoperative ureteral edema and flank pain are substantially diminished. This enables higher rates of tubeless, stent-free discharges in outpatient ambulatory surgery centers (ASCs).
Essential answers for hospital procurement boards, medical device importers, and private-label brand managers.
Comprehensive gastrointestinal and endourology disposables manufactured to international regulatory frameworks.
