Area of Science:

  • Neurosurgery
  • Medical Device Development

Background:

  • Percutaneous needle trephination is an established neurosurgical technique.
  • Existing methods may lack optimal handling and precision.
  • A need exists for improved instrumentation.

Purpose of the Study:

  • To develop a novel instrument for stable fixation of an 18-G spinal needle.
  • To enhance the handling and precision of percutaneous needle trephinations.

Main Methods:

  • A T-shaped, corkscrew-like needle stabilizer was designed.
  • The device allows adjustable length of the uncovered needle tip.
  • 18 percutaneous needle trephinations were performed using the device.

Main Results:
