Hypodermic needle SonoMSK

graduatedechogenic22G

Product overview
SonoMSK is an echogenic musculoskeletal injection needle designed for ultrasound‑guided MSK and chronic pain interventions. A cadaveric study comparing proximal patellar tendon injections found ultrasound‑guided injections reached the exact target in 74% of cases versus 11% for blind injections, demonstrating improved targeting accuracy with MSK ultrasound. The echogenic features of SonoMSK support real‑time tracking during puncture and injection. The sharp back‑cut bevel (16°) is engineered for smooth penetration and needle placement while meeting clinical requirements for musculoskeletal and chronic pain procedures.

Features & advantages

• Sharp bevel: Back cut (16°) designed to reduce tissue resistance during puncture and to facilitate smooth gliding.
• Cornerstone reflectors: 360° graduations on the first 20 mm in two sections to enhance shaft visibility and improve detection at steep insertion angles.
• Depth markings in bold black: Markings every 0.5 cm up to 3.0 cm for quick reading and depth identification.
• Pre‑attached, removable injection tubing: Delivered with detachable tubing for handling flexibility and clinical workflow options.
• Echogenic design: Optimized for ultrasound visibility to support real‑time needle tracking during interventional procedures.
