Area of Science:

  • Neurosurgery
  • Medical Devices
  • Stereotactic Surgery

Background:

  • The Brown-Roberts-Wells stereotactic frame is a foundational tool in neurosurgery.
  • Modifications aim to enhance precision and applicability in complex procedures.

Purpose of the Study:

  • To introduce and evaluate the Cosman-Roberts-Wells stereotactic instrument.
  • To assess its utility in various neurosurgical interventions.

Main Methods:

  • The Cosman-Roberts-Wells instrument, an arc-radius modification of the Brown-Roberts-Wells frame, was used.
  • Existing fixation and fiducial components were leveraged for target localization.

Main Results:

  • 55 procedures were performed over 5 months, including stereotactic biopsies, CT-guided craniotomies, and electrode implantations.
