Echogenic, Stimulating Single-Shot Nerve Block Needles with Removable Stimulation Cable

SonoPlex® needles were specifically developed by PAJUNK® for single-shot nerve block applications, allowing for placement under ultrasound and stimulation techniques (Dual Guidance). The combination of both technologies is especially recommended to reduce the risk of intraneural needle placement.1

SonoPlex II Overview

SonoPlex II Features & Advantages

Cornerstone Reflectors

360° graduations on the first 20 mm of the needle in two sections:

  • Optimized ultrasound visibility of the needle shaft4 and needle tip.
  • Increased needle echogenicity at steep insertion angles compared to nonechogenic needles.4,5,6
NanoLine Coating

Ultra-thin insulating layer in the inner and outer lumen:

  • Small and precise electrodes allow for better stimulation success.7
Depth Markings

In solid black:

  • Helps ensure visualization of insertion depth during needle placement.
Color-Coded Needle Hub
  • For easy identification of the needle size.
Removable Stimulation Cable

Easy removal of stimulation cable while keeping the system sterile:

  • Allows for more flexibility to match user preferences.
Non-removable Injection Tubing
  • Reduces the risk of leakage.
