1. Material Performance: Medical-Grade Stainless Steel for Safety & Durability

Manufactured from medical-grade stainless steel (e.g., 316L/304L), this needle exhibits exceptional biocompatibility, allowing for prolonged contact with human tissues and fluids without inducing allergic or inflammatory reactions. It combines high tensile strength with superior corrosion resistance against disinfectants and bodily fluids. The structure remains stable under high-frequency sterilization (autoclaving, chemical disinfection), significantly extending the product lifecycle and reducing overall healthcare costs.

2. Precision Machining: High-Accuracy Structure Ensuring Marking Reliability

• Precision Cold Drawing & Grinding: The needle body maintains straightness and cylindricity tolerances within ≤0.01mm, ensuring precise marking trajectories and minimizing operational errors (e.g., misalignment or repeated marking).

• Tri-Bevel Tip Geometry: The three-plane cutting edge optimizes piercing sharpness, reducing tissue trauma and patient discomfort. The geometric accuracy of the cutting edges is maintained within ≤0.005mm, ensuring clear, uniform markings without burrs or tissue tearing.

• Seamless Thin-Wall Lumen: Featuring uniform wall thickness (tolerance ≤0.005mm), the needle ensures smooth passage of irrigation fluids or medications, while minimizing the risk of clot obstruction during procedures.

3. Hygiene & Sterilization: Compliance with Infection Control Standards

The stainless steel surface is smooth and free of dead angles (surface roughness Ra ≤ 0.8μm), effectively reducing tissue residue and microbial adhesion. It supports high-temperature autoclaving (134℃/30min) and chemical disinfection (e.g., glutaraldehyde, hydrogen peroxide) without deformation or corrosion, fully complying with hospitals' "single-use, single-sterilization" protocols to mitigate cross-infection risks.

4. Clinical Versatility: Multi-Department Application Coverage

• Surgery / Orthopedics: Functions as a bone marking needle or implant positioning guide. The tri-bevel design creates clear, precise indentations on bone surfaces, assisting in surgical navigation (e.g., joint replacement, spinal fusion).

• Dentistry / Implantology: Ideal for dental tissue marking and implant site preparation, minimizing enamel damage while ensuring high positional accuracy.

• Dermatology / Aesthetics: Assists in lesion mapping and minimally invasive procedure guidance. The three-edge design reduces epidermal trauma compared to standard points, providing superior visibility for incision planning.

5. Customization Capability: Tailored Solutions for Specific Needs

We offer comprehensive non-standard customization services. Parameters such as gauge (21G–27G), length (20mm–100mm), bevel angle (15°–45°), number of facets (2/3/4), and hub interface (Luer lock/straight) can be precisely engineered to meet the R&D and iterative requirements of medical device manufacturers (e.g., surgical navigation systems, minimally invasive tools).
