Echogenic, Stimulating Single Shot Nerve Block Needle

#1 echogenic nerve block needle globally



Echogenic, Stimulating Single Shot Nerve Block Needle

SonoPlex needles were especially developed by Pajunk for single shot nerve block applications, allowing for placement under ultrasound and stimulation techniques (Dual Guidance). As the leading echogenic nerve block needle globally the SonoPlex includes the patented Cornerstone Reflectors for best needle echogenicity possible, irrespective of the insertion angle.

SonoPlex Overview

SonoPlex Features & Advantages

2. Cornerstone Reflectors

  • 360 degree graduations on the first 20 mm of the needle
  • Optimised ultrasound visibility of needle shaft and needle tip
  • Reliable and optimised needle visualisation at any angle

3. NanoLine Coating

  • Very thin polymer film, smooth surface, accurate inner and outer diameter
  • Excellent puncture and gliding properties through smooth surface
  • Improves visibility under ultrasound
  • Precise stimulation through the non-insulated needle tip

4. Depth Markings

  • Easy to read and identify
