从China供应商批量进口304 Grade Surgical Needle

The 304 grade surgical needle from Shanxian Runte Medical Instruments Co., Ltd is a U.S.P standard suture needle manufactured from AISI 304 stainless steel, an austenitic alloy selected for surgical instruments due to its non-magnetic properties, ease of cold working to extreme sharpness, and corrosion resistance in sterile environments. The needles are produced in assorted sizes and types to accommodate tissue-specific suturing requirements, with each box containing 12 pieces. The 304 grade provides sufficient hardness after cold working for needle points and bodies, though some premium surgical needles use 420 or 455 martensitic stainless for higher hardness in heavy-duty applications.

U.S.P standard classification governs needle dimensions, curvature, and point geometry, with common curvatures including 1/4 circle, 3/8 circle, 1/2 circle, 5/8 circle, and straight, and point types ranging from taper point (round body) for soft tissue to cutting point (triangular cross-section with cutting edges) for skin and tough fascia. The 304 stainless steel body is typically drawn to wire, then formed to curvature, heat-treated for stress relief, and electropolished to create a smooth surface that minimizes tissue drag and bacterial adhesion. Siliconization is often applied as a final coating to reduce frictional resistance during passage through tissue, though this must be biocompatible and non-pyrogenic per ISO 10993.

Primary end users include hospital operating theatres, outpatient surgical clinics, veterinary practices, and dental surgery centers. The needles are supplied non-sterile for in-house sterilization or may be offered sterile-packaged depending on configuration. When importing from Shandong Province, buyers should verify CE marking or FDA 510(k) status if marketing in regulated jurisdictions, and confirm whether the 304 grade is certified to ASTM F899 or equivalent surgical material standard. The U.S.P designation indicates conformance to United States Pharmacopeia dimensional and performance standards, which many national regulatory systems reference or recognize.

Shanxian Runte Medical Instruments Co., Ltd is located at No.22 Shidaihuayuan, Wenhua Road, Shanxian, Heze 274300, Shandong Province, China. The company holds both Imported supplier tier and Harbor trust tier designations on the platform, with a response rate showing 0.00% and zero recorded average response hours, indicating no quantified inquiry responsiveness. The Shandong location places it within a province with emerging medical device manufacturing activity, though less concentrated than Jiangsu or Zhejiang medical device clusters.

The supplier profile provides no verified information regarding manufacturing facility size, ISO 13485 medical device quality management certification, FDA registration number, or named hospital or distributor clientele. The source description references U.S.P standard and 304 grade material, but buyers must independently verify material certification, sterility assurance level if applicable, and any claimed international medical standards compliance. The company's capacity for custom needle configurations, such as proprietary curvatures or attached suture types, should be discussed directly with the supplier.
