Carpal Tunnel Release with Ultrasound Guidance

Carpal Tunnel Release with the SX-One MicroKnife® and Ultrasound Guidance

When you perform carpal tunnel release with the SX-One MicroKnife and ultrasound guidance, you will see all of the critical anatomy in the wrist and hand. You will identify the safe zone and create space to transect the TCL while protecting sensitive anatomic structures.

Benefits include4,9,10

  • Most patients can return to work and the activities they love within 3-6 days
  • Performed in a procedure room or office setting using local anesthesia
  • Small incision typically closed without sutures
  • Most patients only require acetaminophen or NSAIDs for pain management
  • Postoperative therapy typically not required
  • Immediate motion of the hand for rapid recovery

Simple, Elegant, Safe and Effective

The SX-One MicroKnife features:

  • The low profile tapered tip allows the device to be inserted through a small incision (~5mm).
  • Stealth MicroGuard® balloons gently expand and maintain the safe zone* prior to and during transection.
  • Meerkat Technology® – the TCL Blade® is hidden in the tip of the device for safe insertion and removal.
  • The TCL Blade cannot be activated unless the Stealth MicroGuard balloons are inflated.

* The transverse safe zone is the space between the ulnar edge of the median nerve and the radial edge of the ulnar artery or hook of the hamate, whichever is closest.

Carpal Tunnel Release with the SX-One MicroKnife and Ultrasound Guidance

  1. Throughout the procedure, the transverse carpal ligament and relevant anatomic structures are visualized directly, in real-time, with ultrasound imaging.
  2. The SX-One MicroKnife is inserted through a small incision (~5mm) over the proximal carpal tunnel region.
  3. Meerkat Technology coordinates the activation of the TCL Blade and the inflation of the Stealth MicroGuards.
    • The TCL Blade is initially positioned entirely within the tip and shaft of the SX-One MicroKnife and can only be activated after the Stealth MicroGuards are deployed.
  4. Once in position and the Stealth MicroGuards deployed, the TCL Blade is advanced from the tip of the device to transect, or divide, the transverse carpal ligament.
  5. The TCL Blade is returned to the inactive position, within the tip and shaft of the device, and the Stealth MicroGuards are deflated.
  6. The SX-One MicroKnife is removed and the small incision can be closed with an adhesive strip, bandage or sutures as needed.

My patients are very satisfied with their speedy recovery. I’ve had many say that the night after surgery was the first time they’ve slept through the night in months.
