Direct manufacturer supply spanning endoscopic tissue acquisition, active mechanical hemostasis, and fluoroscopy-guided biliary tract interventional consumables.
Understanding the micro-tribological friction, mechanical shearing forces, and structural metallurgy required to eliminate bio-burden in 1.2 mm to 6.0 mm internal instrument lumina.
Twisted 304/316L medical stainless steel core wires provide calibrated torsional rigidity, preventing helical buckling inside complex tortuous colonoscopic geometries while delivering full 360-degree circumferential contact.
Micro-welded smooth polymer or precision epoxy bulb tips protect sensitive PTFE/polyurethane endoscope liners from gouging or puncture, preserving scope lifespan and preventing hidden bacterial pockets.
Utilizing high-purity medical-grade Polyamide 6.6 or PBT micro-bristles with uniform filament ends. Designed to flex and sweep dry coagulated proteins without shedding fiber particulates into channels.
From single-head manual brushes to smart dual-ended continuous-pass cleaning rods: exploring mechanical properties across our OEM/ODM custom product lines.

Traditional single-pass brush systems with manual twisted wire. Excellent cost efficiency for high-turnover ambulatory surgery centers requiring volume-based purchasing.
Continuous-feed brushes featuring dual heads of differing bristle stiffness. Head 1 shears hard encrustations; Head 2 sweeps colloidal micro-particles in a single technician stroke.
Innovative coated polymer sheathing chemically formulated to interact synergistically with neutral-pH enzymatic detergents, accelerating breakdown of blood and mucin.
Strategic alignment with CDC, FDA Medical Device Alerts, and AAMI ST91:2021 mandates for multi-drug resistant organism (MDRO) containment.
Duodenoscopes represent the most complex reprocessing challenge. ZhuoRuiHua designs specialized ultra-compact micro-tufted brushes to navigate around the elevator recess, eradicating Carbapenem-Resistant Enterobacteriaceae (CRE) reservoirs.
Scratches created by sub-standard metal brushes create microscopic crevices where biofilms anchor permanently, immune to liquid chemical germicides. Our polymer-shielded assemblies eliminate channel scratching completely.
Color-coded pull handles and distinct catheter lengths allow central sterile technicians to immediately match the correct brush French/millimeter size to gastroscopes, colonoscopes, or bronchoscopes without error.
Transitioning hospital systems from reusable to single-use cleaning instruments eliminates the labor-intensive, error-prone manual brush cleaning cycle, completely removing this vector of nosocomial transmission.
Inside Jiangxi ZhuoRuiHua Medical's automated production infrastructure: High-speed automated bristle tufting, class 100,000 cleanroom assembly, and 100% inline tensile testing.
Robotic winding machinery ensures consistent tension along the entire length of the stainless steel core wire, eliminating variations in diameter that could cause friction spikes inside narrow endoscope channels.
All extrusion, tufting, cutting, ultrasonic tip-forming, and initial packaging take place under ISO Class 8 (100,000 level) environments to guarantee non-pyrogenic, particulate-free consumables prior to sterilization.
By producing medical tubing, stainless core cables, and customized molded connectors under one roof in Jiangxi, ZhuoRuiHua offers OEM partners agile scalability, rapid custom tooling, and insulation from global logistics volatility.
From private labeling and custom length packaging to sterile blister packs and bulk non-sterile hospital kits: tailored contract manufacturing to your exact specifications.
Custom brush diameters from 1.0 mm to 15.0 mm; working lengths ranging from 10 cm for valve cylinders to 300 cm for ultralong enteroscopes, single-ended, double-ended, or dual-action stepped configurations.
Private label printing, full color carton boxes, multi-language instructions for use (IFU), unique device identification (UDI) barcoding, and GS1 compliance to integrate seamlessly into hospital replenishment systems.
Supplied as individually sealed Ethylene Oxide (EO) sterile packs (compliant with ISO 11135 validation) for immediate surgical endoscope reprocessing, or clean non-sterile bulk packaging for custom reprocessing kit packagers.
Rapid 3D CAD modeling and pilot micro-tooling allow us to deliver bespoke functional prototypes within 10-14 business days, significantly reducing time-to-market for medical device distributors and contract brands.
Ensuring frictionless international import, hospital tender qualification, and stringent risk management through certified medical quality management systems.
Our complete manufacturing pipeline operates under accredited ISO 13485:2016 medical device quality standards, establishing end-to-end traceability from raw filament lots to final customer shipments.
Supported by comprehensive technical documentation files (STED), biocompatibility test protocols (ISO 10993 cytotoxicity, sensitization, systemic toxicity), and shelf-life accelerated aging validation.
We supply established distributors across Europe, North America, Latin America, and Southeast Asia. We provide customs clearance documentation, certificates of origin, and certified factory analysis reports.
