Medical Device Registration, Standards & In-Hospital Management Of PTC Needles

https://admin1.seo.com.cn/CustomerAdmin/S_News/Create?ru=%2FCustomerAdmin%2FS_News%2F

NMPA Classification (China)

PTC/Chiba puncture needles for interventional use (biopsy, biliary access, drainage)​ → Class III​ medical device

Classification code: 02-07-01​ (Percutaneous puncture instrument) per latest Medical Device Classification Catalog

Required for registration:

• Product Technical Requirements (refer to GB 15811 / ISO 7864, YY/T 0282, YY/T 0616 for biopsy claim)
• Type testing (CNAS-accredited lab)
• Biological evaluation (ISO 10993 / GB/T 16886)
• EO sterilization validation (ISO 11135 / GB 18279)
• Clinical evaluation (literature + substantial equivalence or clinical trial)
• Risk management file (ISO 14971 / YY/T 0316)

IFU & labeling

Applicable Standards

• GB 15811 / ISO 7864:​ Sterile hypodermic needles - dimensions, strength, leakage, tip
• YY/T 0282:​ Hypodermic needles (partial adoption)
• YY/T 0616 series:​ Biopsy needles
• ISO 9626:​ Stainless steel needle tubing
• ISO 11607 / GB/T 19633:​ Packaging for terminally sterilized devices
• ISO 13485:​ Quality management (manufacturer must hold cert + pass NMPA QS audit)

Labeling & IFU Must Include

Name: "Disposable Sterile PTC Puncture Needle / Chiba Needle"

Gauge, length, bevel angle, material

Intended use: "Image-guided percutaneous fine-needle aspiration, biliary/cystic puncture, initial access for micro-puncture system"

Contraindications & warnings: coagulopathy, infection along path, single-use only, no re-sterilization

LOT No., expiry date, sterilization method, registration certificate No., manufacturer info

Hospital Procurement & Admission

• Qualification Review:​ NMPA Class III cert (scope covers biopsy / percutaneous puncture), Mfg License, ISO 13485, batch COA, sterilization cert
• Tender Tech Parameters:​ Bevel angle (25°±3° for 22G–23G), max penetration force (e.g., ≤0.6 N), inner surface Ra, presence of echo ring / depth marks, Luer lock integrity, EO residue limit
• SPD / UDI:​ Scan & track by UDI (Device Identifier + Production Identifier); expiry alert & recall readiness
• Adverse Event Reporting:​ Needle fracture, abnormal breakage, suspected particulate reaction → NMPA ADR surveillance system
• User Training:​ Manufacturer/agent to demo micro-puncture exchange, suction technique, echo tip use; incorporate into department SOP

Import Considerations

Imported Chiba needles require NMPA import registration ("国械注进" No.)​ - CE/FDA alone insufficient for China market

Customs docs: original COA, CFS (Certificate of Free Sale), pre-approved Chinese label artwork

Robust regulatory compliance ensures only genuine, performance-validated Chiba needles reach the procedure room - protecting both patient safety and institutional liability.
