SHOMEA Medical-Grade Barbed Needle

Product Specification

• Validated through biocompatibility testing (ISO 10993), sterilization tolerance verification (autoclave/ETO/irradiation), and fatigue life testing (≥10⁶ cycles), compliant with medical device quality management system (ISO 13485). Ensures non-toxic, non-irritating, non-pyrogenic​ performance in clinical applications, supporting long-term indwelling or repeated use.

• Supports flexible customization of needle diameter (20G-30G), barb density (1-5 pcs/cm), barb angle (30°-60°), needle length (10mm-100mm), etc., meeting precise needs across minimally invasive surgery, interventional radiology, veterinary medicine, laboratory research​ and other scenarios.

• Inner diameter treated via electrolytic polishing + ultrasonic cleaning, with inner wall roughness Ra ≤0.2μm, significantly reducing medicine residue and cross-contamination risk, facilitating rapid flushing and medicine replacement for improved operational efficiency.

• The entire needle tube adopts an anti-kinking reinforcement structure, maintaining lumen patency even under bending or twisting operations​ (e.g., intra-articular infusion, tortuous cavity passages), preventing blockage or flow reduction due to deformation.

Why Choose SHOMEA Barbed Needles?​

Because we don’t just provide “needles”—we deliver precision solutions for medical fluid control—every step from material, structure, process to validation is engineered for safety, stability, and efficiency.

FAQs:

Q: What is the "barbed" design? What is its core function in practical use?

A: The "barbed" design refers to micron-level micro-protrusion structures​ integrated on the outer wall of the needle. When the tip punctures into tissue or material, these barbs instantly open and embed into the target surface. Its core function is to create a mechanical locking effect, effectively preventing the needle body from slipping or shifting during infusion, aspiration, or retention—ideal for soft tissue anchoring and targeted medicine delivery.

Q: Can the specifications of the barbs (size, angle, spacing) be customized?

A: Yes, we offer full-parameter customization services. The height of the barbs (typically ≤0.05mm), spread angle (default 30°-45°, adjustable), and spacing between barbs can all be precisely designed and produced based on your specific application needs​ (such as tissue hardness, puncture depth, fluid pressure, etc.) to ensure optimal anchoring performance and tissue compatibility.

Q: In which medical fields or specific operations is this barbed needle mainly used?

A: Primarily used in soft tissue anchoring and fixation​ (e.g., assisted thread lifting in aesthetic medicine, surgical suture reinforcement), targeted medicine/nutrient infusion​ (preventing fluid extravasation), catheter fixation in minimally invasive surgery, and tissue puncture and fluid transfer in laboratory animal experiments. It is an ideal choice for any scenario requiring prevention of needle dislodgement or enhanced directional fluid delivery.
