• Both the inner lumen and the double-groove surfaces undergo ultra-precision electropolishing and mirror-grinding treatment, achieving a surface roughness of Ra < 0.1μm. This extreme smoothness not only ensures very low resistance for fluid flow, improving infusion efficiency, but more importantly, it minimizes medicine residue and crystal precipitation, meeting the contamination-free requirements for high-purity pharmaceutical (e.g., contrast agents, chemotherapeutic drugs) delivery.
• Featuring an innovative design of two parallel and equally wide micro-grooves precisely machined at the needle tip, with slot width tolerances strictly controlled within ±0.01mm. Compared to traditional single-hole or bevel-hole designs, the double-groove structure creates a wider and more stable liquid flow beam, effectively reducing shear force and tissue impact during fluid ejection. It is particularly suitable for minimally invasive surgical scenarios requiring extensive irrigation, continuous low-pressure perfusion, or uniform spraying of cells/medication.
FAQs:
Q: How are the dimensions and cutting precision of the grooves controlled? Can it ensure the uniformity of fluid flow?
A: We utilize ultra-precision micro-milling or laser cutting technology, combined with high-magnification microscope online inspection. The slot width tolerance is strictly controlled within ±0.01mm, and the two grooves maintain absolute parallelism and symmetry. This high consistency ensures synchronous and equal liquid output from both sides, preventing clinical operational deviations caused by uneven flow rates.
Q: What is the roughness of the inner wall of the needle tube and the groove surface? Can it effectively prevent liquid residue?
A: Both the inner lumen of the needle tube and the double-groove surfaces undergo ultra-precision electropolishing and mirror-grinding treatment, achieving a surface roughness of Ra < 0.1μm. This extreme smoothness not only reduces flow resistance but, more importantly, significantly minimizes the risk of liquid residue and crystallization, making it ideal for delivering high-purity, high-viscosity, or easily crystallized agents (e.g., contrast media, chemotherapeutic medicine).
Q: What is the material of the product? Does it comply with biocompatibility standards?
A: The main body is made of medical-grade 316L stainless steel (other materials such as PEEK or titanium alloy can be customized upon request), undergoing strict vacuum solution treatment and cold-drawing processes. The material fully complies with ISO 10993 biocompatibility standards, possessing excellent corrosion resistance and mechanical strength. It can be safely used in human cavities or tissue contact without causing allergic or toxic reactions.
