SonoPlex® II

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. The next generation SonoPlex II combines the proven needle shaft and needle tip visibility with a newly optimised needle hub.

SonoPlex II Overview

SonoPlex II Features & Advantages

1. Echogenic Needle Tip

  • Facet tip with two inclination angles
  • Improves needle tip visibility under ultrasound

2. Cornerstone Reflectors

  • 360 degree graduations on the first 20 mm of the needle
  • Optimised ultrasound visibility of needle shaft and needle tip1
  • Reliable and optimised needle visualisation at any angle2,3

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 ultrasound3
  • Precise stimulation through the non-insulated needle tip

4. Depth Markings and Smooth Needle Surface

  • Easy to read and identify

5. Removable Stimulation Cable

  • Easy removal of stimulation cable while keeping the system sterile
  • Allows for more flexibility to match user preferences

6. Non-Removable Injection Tubing
