Precision-turning, stable connection and zero offset
The tail flange seat is CNC precision-turned, concentricity ≤0.01mm, outer diameter tolerance ±0.02mm,
seamlessly connecting to syringes, catheters, or dedicated medical
fixtures, ensuring zero needle deviation and zero medicine leakage during puncture.
Strict sterilization,compatible with multiple disinfection schemes
Compatible with autoclaving (121℃/30min), ethylene oxide (ETO), and low-temperature
plasma sterilization. Hardness and toughness remain unchanged after sterilization,
ensuring stable performance for reusable (if designed) or
single-use scenarios.
Adapt to multiple medical scenarios
Tip taper angle (15°-45° optional), flange outer diameter (2mm-10mm
optional), total length (10mm-50mm optional) — all customizable to
perfectly fit multidisciplinary clinical needs such as local anesthesia, minimally invasive biopsy, acupoint injection,
dental pulp therapy.
FAQs:
Q: What is special about the tip design of this solid pen nib
needle?
A: The tip adopts micro-tapered polishing + diamond-cut edge technology, with a diameter finely controlled to ≤0.1mm
(customizable to finer). Ultra-low puncture resistance enables
precise penetration of skin, mucosa, or hard tissues (e.g.,
periosteum, fascia), while minimal lateral tissue trauma reduces infection risk and tissue repair burden.)
Q: Is the material medical-grade? Can it withstand high-frequency
sterilization?
A: Made from 316L medical-grade stainless steel (or equivalent high-spec alloy), reinforced via vacuum heat treatment + cold drawing precision grinding. It offers excellent biocompatibility (compliant with ISO 10993),
high temperature & corrosion resistance, and can safely undergo autoclaving (121℃), ethylene oxide (ETO), or irradiation sterilization — maintaining
stable performance even after repeated use.
Q: What is the function of the threaded tail and flange? How is it
installed and fixed?
A: The threaded tail + flange structure is designed for mechanical fixation and depth limitation: the thread allows screwing into dedicated fixtures, syringes, or
device interfaces to prevent slippage during operation; the flange
acts as a physical stop to ensure consistent insertion depth,
avoiding over-penetration or fluid leakage.
Q: Does it support customization? Such as size, tip shape, or
connection end?
A: Full-dimensional customization is supported: tip diameter (from
0.05mm), cone angle, effective length, tail thread specification
(e.g., M6, M8), flange outer diameter/thickness — even special
shapes like beveled, rounded, or side-hole tips can be customized to meet precise needs in different medical
scenarios (e.g., neurosurgery, ophthalmology, minimally invasive
intervention).
Q: In which medical or experimental scenarios is it suitable?
A: Widely used in: neurosurgery (epidural/intrathecal medicine delivery),
ophthalmology (anterior chamber puncture, intravitreal injection),
minimally invasive intervention (tumor local perfusion, tissue
biopsy guidance), laboratory animals (precise gavage/biopsies in
mice/rats), and medical aesthetics (microneedle delivery, local
filling) — all high-precision procedures.
Q: How is batch-to-batch consistency and precision ensured?
A: Full-process CNC machining + laser diameter gauge online inspection — every needle’s tip diameter, cone angle, length, and thread
precision are 100% fully inspected and recorded, with tolerances controlled within ±0.01mm, ensuring highly
consistent performance across batches to meet strict medical-grade
requirements.
