SHOMEA Customized Stainless Steel Solid Pencil Point Needle With Thread

PRODUCT DESCRIPTION:

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.
