What endoscopic accessories does ZhuoRuiHua Medical manufacture?

Our portfolio covers 19 device categories across six clinical pathways: tissue sampling (biopsy forceps, hot biopsy forceps, cytology brushes), hemostasis (hemoclips, endoclips), EMR/ESD (polypectomy snares, injection needles), ERCP (sphincterotomes, hydrophilic guidewires, biliary drainage catheters), urology (negative-pressure ureteral access sheaths, nitinol stone extractors) and reprocessing accessories (bite blocks, cleaning brushes).

Do you support OEM and private-label supply for distributors?

Yes. We work with distributors and brand owners on private-label packaging and specification adjustments such as working length, channel compatibility and jaw or loop design. Share your target specification and market with sales@zrhmed.com to receive a feasibility review.

Which specifications should I confirm before ordering endoscopic accessories?

Confirm the minimum endoscope working-channel diameter, working length, intended procedure, single-use versus reusable status, sterilization method, shelf life and the regulatory documents required in your destination market. Our product pages and catalog list these parameters per model.

How can I verify regulatory and quality documents?

Certificate scope differs by product and market. Request copies of the quality-system certificate, product registrations and test reports for the exact models you plan to import, and our team will provide documentation matched to each SKU.

Where can I meet ZhuoRuiHua Medical in person?

We attend international gastroenterology and medical-device events, including CMEF in China and SBAD 2026 (Brazilian Digestive Disease Week) in Fortaleza, Brazil, from 19 to 21 November 2026.

✅ Core Uses

EMR/ESD lifting: Inject fluid to raise the lesion before resection. (Lift – Inject fluid beneath a polyp to raise it before cutting.)
Sclerotherapy: Deliver sclerosant into varices or hemorrhoids. (Inject – Deliver sclerosant directly into varices or hemorrhoids.)
Contrast injection: Inject dye for fluoroscopic guidance. (Dye – Push contrast through the needle for fluoroscopic imaging.)
Drug delivery: Administer local therapeutic agents. (Treat – Infuse medication exactly where the lesion lives.)
Tattooing: Mark lesions for future surgical localization. (Mark – Place a tattoo next to a lesion for surgical navigation.)

Q1: What are the main clinical applications of this endoscopic injection needle?

This single-use device is primarily designed for fluid injection during endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), endoscopic sclerotherapy for esophageal and gastric varices or hemorrhoids, contrast dye delivery for fluoroscopy, tattooing for surgical localization, and targeted drug administration.

Q2: How does the design protect the endoscope channel from damage?

The device features an easy-to-operate retractable needle system and a low-friction PTFE outer sheath. The needle remains safely retracted within the protective sheath during insertion and advancement, preventing any scratching or puncturing of the flexible endoscope working channel.

Q3: Which models are most commonly recommended for standard procedures?

The most popular configurations are model ZRH-PN-2418-234 (Φ2.4mm outer diameter, 1800mm working length, 23G needle with 4mm extension) and model ZRH-PN-2423-236 (Φ2.4mm outer diameter, 2300mm working length, 23G needle with 6mm extension). Both require a working channel of ≥2.8mm.

Q4: What material grades and quality standards are applied?

The puncture needle is made of medical-grade 304 or 316 stainless steel with a tested penetration force of ≤0.5N to ensure effortless puncture. The handle is made of medical-grade ABS with a secure Luer lock, the sheath passes a 180° kink-resistance bend test, and the entire device is sterilized by Ethylene Oxide (EO).

Q5: What is the typical lead time and available international shipping terms?

The standard production lead time is typically 2 to 3 weeks following payment confirmation, depending on order size. Orders can be shipped via Express, Air, Sea, or Road under flexible Incoterms including EXW, FOB, CIF, DDP, CFR, and others, accompanied by standard documentation (B/L, Commercial Invoice, Packing List).
