• Customizable according to customer needs regarding taper ratio, total length, outer diameter specifications, and tip geometry (e.g., beveled, blunt, side-hole, etc.). It can perfectly adapt to various medical components such as syringes, indwelling needles, drainage tubes, and biopsy needles, widely used in various high-end medical fields including central venous catheterization, neurointerventional guidewire guidance, local anesthesia, and cell collection.
FAQs:
Q: Is the transition of the tapered section smooth? Is there any risk of a "stepped" feel causing snagging?
A: Our tapered needles utilize high-precision CNC centerless grinding or micro-EDM (Electrical Discharge Machining) processes to ensure the transition section is free of any visually perceptible steps or grooves, maintaining a mirror-like finish (Ra≤0.2μm) on both inner and outer walls. This technique eliminates stress concentration points, allowing the needle to pass through catheters or tissues smoothly without obstruction, completely avoiding snagging or tissue scraping caused by abrupt diameter changes.
Q: In which specific medical scenarios are these small-diameter tapered needles mainly used?
A: These needles are particularly suitable for minimally invasive interventional scenarios requiring extreme precision. Typical applications include: guidewire exchange within microcatheters, superselective angiography and embolization, establishment of distal access in neurointervention, and micro-volume medicine injection in ophthalmic or microsurgical procedures. Their fine tips can access distal peripheral areas that are difficult for conventional instruments to reach.
Q: What tip shapes are available? Is side-hole (Side Port) design supported?
A: We support fully customized tip forming. In addition to the standard bevel tip, we can produce blunt tips, pen tips (bent/curved tips), and incorporate side-hole ports on the tapered section or tip upon request. Side-hole design is often used in scenarios requiring "tangential perfusion" or "tip clog prevention," effectively dispersing fluid pressure and protecting vessel walls.
Q: For such small-diameter, tapered precision needles, how do you ensure concentricity and straightness?
A: Ensuring precision is at the core of our process. We utilize Swiss-type automatic lathes for integral forming and employ laser online inspection systems during machining to monitor dimensional changes in real-time. For extremely slender tapered needles, we perform straightening and stress relief treatments to ensure the entire needle maintains a concentricity of ≤0.01mm and straightness that complies with the stringent standards of medical interventional devices, preventing operational failure due to needle bending.
