Area of Science:

  • Neurosurgery
  • Medical Device Development
  • Neuromodulation

Background:

  • Deep brain stimulation (DBS) is increasingly used for movement disorders and chronic pain.
  • Accurate placement of DBS electrodes is crucial for successful treatment.
  • Current methods may require fluoroscopic guidance, impacting efficiency and accuracy.

Purpose of the Study:

  • To describe a novel DBS electrode lead stabilization device.
  • To enhance the accuracy and ease of final DBS electrode lead placement.
  • To provide a reliable tool for neurosurgical procedures.

Main Methods:

  • A two-clamp system designed for the Leksell stereotactic frame was developed.
  • The device secures the stereotactic lead during final positioning at the subcortical target.

  • It eliminates the need for intraoperative fluoroscopic control.

    • Main Results:

    • The stabilization device was used in 54 electrode implantations across 30 patients.
    • Postoperative MRI confirmed accurate electrode placement in all cases.
    • The device has been successfully utilized since 2000.

    Conclusions:

    • Accurate DBS electrode placement is essential for clinical efficacy.
    • The described stabilization device is simple, reliable, and easy to operate.
    • This device significantly enhances the final placement accuracy of DBS electrode leads.
