Engineered for absolute accuracy in submucosal lifting, mucosal resection, GI hemostasis, and endourology interventions.
Submucosal fluid cushioning, targeted hemostasis injection, and endoscopic tattooing demand an injection catheter that maintains strict structural integrity across tortuous anatomies.
Our CE-certified endoscopic injection needles feature CNC-ground, back-beveled lancet tips fabricated from medical-grade 304/316L stainless steel. This proprietary geometry minimizes penetration resistance, eliminating tissue tearing and preventing inadvertent deep-wall perforation during EMR/ESD procedures.
Extruded using biocompatible PTFE or fluoropolymer composites, the dual-sheath assembly balances flexibility with superior column strength. Even when navigating acute scope angulation up to 210 degrees, the needle smoothly extends and retracts without core-wire buckle or channel binding.
Featuring an ergonomic one-handed actuation handle with positive tactile and acoustic lock positions, clinicians receive unmistakable feedback at 4mm, 5mm, and 6mm projection lengths. This locking mechanism prevents inadvertent needle protrusion during scope insertion, protecting instrument working channels.
Jiangxi ZhuoRuiHua Medical leverages vertical integration—from custom polymer extrusion to high-speed robotic assembly—to guarantee volume consistency and international supply security.
Unlike repackaging operations, ZhuoRuiHua designs, micro-machines, and validates injection molds and bevel-grinding fixtures entirely in-house. This gives international OEM/ODM clients total control over custom gauge diameters (21G, 22G, 23G, 25G) and bespoke catheter lengths (1600mm to 2400mm).
Every single lot is subjected to comprehensive three-stage quality gates: raw material spectroscopy & tensile verification, in-process optical measurement of needle bevel runout, and automated burst-pressure testing up to 800 kPa, fully tracked via MES systems.
Our Jiangxi campus maintains rolling 6-month buffer stocks of precision-drawn medical tubing and pharmaceutical resins. This strategic inventory shields international partners from global supply chain volatility, raw material surges, and lead-time bottlenecks.
As therapeutic endoscopy expands toward complex ESD, third-space endoscopy (POEM/STER), and interventional EUS, our engineering team is establishing new benchmarks in needle design.
Emerging synthetic submucosal lifting agents present high fluid dynamic viscosity. ZhuoRuiHua is optimizing inner-lumen hydrodynamics with ultra-thin wall (UTW) cannula engineering, enabling high-viscosity hydrogel injection with 45% less hand pressure.
Our Phase III R&D pipeline integrates RF/Electrosurgical monopolar conductivity directly through the distal tip, allowing immediate micro-vascular coagulation following fluid lifting without removing the injection device from the biopsy channel.
Pioneering sustainable medtech manufacturing, ZhuoRuiHua is actively evaluating recyclable fluoropolymer alternatives and medical polyolefins that substantially diminish carbon footprint while complying with EU MDR biocompatibility mandates.
We structure streamlined contract-manufacturing programs for medical device multinationals, private label brands, and regional distributors worldwide.

International hospital tenders require flawless documentation. Our regulatory affairs unit provides continuous, dedicated registration support across the Americas, Europe, Asia-Pacific, and the Middle East.
We maintain contracted, experienced European authorized representatives to streamline post-market surveillance (PMS), vigilance reporting, and seamless clearance through EU customs borders under current MDR protocols.
Every export order is accompanied by Certificates of Analysis (CoA), sterilization certificates, needle tensile pull-test certificates, and corrosion-resistance validation documents correlated precisely to batch identification numbers.
Hospital tenders often contain hyper-specific wording regarding distal tip tapers, sheath outer diameters, or syringe Luer-lock geometries. Our specialized sales engineering desk assists distributors in drafting exact compliance responses.
Integrate all your diagnostic biopsy, endoscopic ligation, and biliary tract requirements under one ISO 13485 certified manufacturer.
Clear, authoritative information compiled for biomedical engineers, regulatory directors, and medical product distributors.
