Quality Control System & Safety Compliance Standard Of 16G-27G Stainless Steel Spinal Needle

As a Class III invasive medical device directly acting on human spinal canal and cerebrospinal fluid, the 16G-27G Medical Grade Stainless Steel Spinal Needle implements strict full-process quality control and international compliance standards in raw material selection, production and processing, precision polishing, sterilization and packaging. Perfect quality control system is the core guarantee for its stable clinical safety and long-term market recognition in the global medical device industry.

In the raw material procurement stage, all needle bodies are made of high-purity medical-grade stainless steel, which has passed international medical material biocompatibility certification. The manufacturer conducts strict sampling tests on each batch of raw materials, including corrosion resistance test, mechanical tension test, cytotoxicity test and metal precipitation detection, to eliminate unqualified raw materials from the source. All raw materials have complete traceability reports to ensure that every needle meets invasive medical device safety standards.

In the production and processing stage, integrated one-piece molding technology is adopted for all 16G-27G gauges, without welding gaps and splicing dead angles, avoiding bacterial residue and cleaning dead space. The needle shaft is polished by micron-level mirror surface to ensure smooth and burr-free surface, reducing tissue friction damage during puncture. The tip grinding strictly unifies the angle and radian standards of Quincke Point and Pencil Point, with zero error in concentricity, ensuring consistent puncture force and positioning accuracy of each product. The whole production process is carried out in a 100,000-class dust-free sterile workshop to prevent secondary pollution.

Sterilization treatment adopts professional ethylene oxide sterilization process, with strictly controlled sterilization temperature, pressure and time parameters. After sterilization, sufficient degassing analysis is carried out to completely eliminate sterilant residues, ensuring that the product has no irritation to human spinal tissues and cerebrospinal fluid. Each batch of products undergoes strict sterility test, pyrogen test and microbial residue test to ensure 100% sterile compliance, meeting the global single-use medical device management specifications.

Finished product inspection covers multi-dimensional full-item detection, including size calibration of 16G-27G full gauges, color code consistency inspection, needle shaft rigidity and flexibility test, simulated clinical puncture performance test, and packaging tightness inspection. Unqualified products such as deformed needle bodies, blurred color codes and unqualified penetration performance are fully screened out to ensure that the qualified rate of factory products reaches 100%.

In terms of packaging and transportation compliance, standard carton packaging and customized sterile independent packaging both meet international medical device storage and transportation standards, with moisture-proof, dust-proof and anti-collision functions. Each product is marked with complete specifications, batch number, sterilization date and validity period information, realizing full lifecycle traceability. Strict quality control and compliance system make the 16G-27G Medical Grade Stainless Steel Spinal Needle meet the access standards of global mainstream medical markets and become a high-quality compliant product trusted by medical institutions worldwide.
