Nerve stimulation needle RFTL Sono

echogenic20G22G

Product overview
PAJUNK offers a range of straight echogenic needles specifically developed for temperature-controlled radiofrequency (RF) peripheral procedures. The RFTL Sono needles combine patented Cornerstone Reflectors with a smooth coating and an active bevel tip to facilitate precise placement under ultrasound guidance and controlled thermolesion delivery.

Features & Advantages

• Cornerstone Reflectors
  • 360-degree graduations on the first 20 mm of the needle
  • Optimised ultrasound visibility of the needle shaft
  • Consistent echogenic response at higher insertion angles
• Bevel Tip with Back Cut and Active Tip
  • Reduced puncture-related pain during insertion
  • Improved needle manoeuvrability and positioning precision
  • Smooth gliding at tissue interfaces
• Smooth Needle Coating
  • Low friction coating for easier placement
  • Uniform tapered insulation along the shaft
  • Enhanced dielectric strength for RF applications
