FAQ:

Question: How is the precision and quality of the thread? Will there be thread stripping or breakage during use?​

Answer:​ Our threads are processed by high - precision CNC rolling/cutting technology, with full thread teeth and uniform pitch. The fit tolerance is strictly controlled within the medical - grade standard range. At the same time, the mechanical strength (tensile, torsional) of the solid needle body is optimized, which can withstand the loads in the routine operation of medical devices. Under normal use, thread stripping or breakage is not easy to occur.

Question: Has the product surface been specially treated? Can the cleanliness meet the medical requirements?​

Answer:​ The product surface is treated by electrolytic polishing/mechanical polishing, with low surface roughness (Ra≤0.4μm), which not only reduces the risk of bacterial adhesion but also improves the puncture smoothness; The production process follows the medical - grade clean room standard, and the finished product is cleaned by ultrasonic cleaning and sterilized (ethylene oxide/irradiation sterilization is optional), and the cleanliness meets the requirements of ISO 14644 - 1 Class 7 (or customer - specified) clean room.

Question: Can we customize the thread specifications and needle body dimensions according to our medical device design?​

Answer:​ Absolutely! We support non - standard customization. According to your drawings or needs, we can customize the pitch, thread form, needle body diameter/length, tip shape (such as puncture tip, flat tip, beveled tip, etc.) of the thread, and provide DFMEA (Design Failure Mode and Effects Analysis)​ support to ensure that the customized product perfectly matches your device.

Question: In which medical scenarios is this solid threaded needle mainly suitable? Can it be compatible with our catheter/device?​

Answer:​ It is widely used in scenarios such as minimally invasive interventional devices (e.g., catheter fixation, tissue anchoring), orthopedics/trauma repair (e.g., bone needles, suture anchors), diagnostic equipment (e.g., biopsy needle assistance, sample extraction). Our technical team can intervene in advance, and verify the compatibility with your catheter/device through prototype sampling + mechanical testing (e.g., tensile test, puncture force test)​ to ensure functional matching.
