• With special toughness-enhancing heat treatment, it maintains extremely high hardness while effectively reducing material brittleness. Even when facing irregular bone structures or complex puncture angles, the cannula retains good flexibility and resilience, avoiding the risk of brittle fracture and residual fragments, ensuring medical safety.

• The inner and outer walls undergo multi-layer electropolishing and ultrasonic cleaning, achieving ultra-high surface finish (Ra ≤0.2μm). The inner wall is mirror-smooth, significantly reducing fluid resistance for bone marrow fluid, tissue debris, or contrast agents, ensuring unobstructed aspiration and minimizing sample adhesion to the tube wall, thereby improving diagnostic accuracy.

FAQs:

Q: What is the cutting process of the needle tip? Will it cause unnecessary damage to bone tissue?

A: The tip and cutting edge utilize high-precision laser cutting and grinding technology, featuring a mirror-like smooth edge without burrs. This process endows the cannula with excellent cutting force and chip removal performance, allowing smooth entry into bone tissue, minimizing patient discomfort and surrounding tissue tearing, while also preventing internal needle damage or bone marrow sample contamination caused by jamming.

Q: What surface treatment processes are available? Do they meet medical sterility requirements?

A: The product surface can undergo electrolytic polishing​ to significantly reduce surface roughness, enhance corrosion resistance, and improve smoothness; passivation treatment is also available upon request. Before leaving the factory, all products undergo strict ultrasonic cleaning and sterilization packaging, complying with medical-grade sterility standards, and can be directly used in clinical settings or as components of sterile medical devices.

Q: What is the minimum order quantity (MOQ)? What is the lead time?

A: For standard products, our MOQ is relatively flexible. For fully customized non-standard items, the MOQ is typically evaluated based on specific processing difficulty and craftsmanship requirements, generally starting from [Fill in specific number, e.g.: 1000]​ pieces. The lead time for standard products is approximately 2-3 weeks, while customized products usually take around 4-6 weeks​ depending on complexity.
