Area of Science:

  • Neurosurgery
  • Medical Devices
  • Image-Guided Therapy

Background:

  • Stereotactic surgery enables precise targeting of intracranial structures.
  • Computer-assisted surgery enhances accuracy in neurosurgical interventions.
  • Deep-seated intracranial lesions pose challenges for conventional surgical approaches.

Purpose of the Study:

  • To introduce a novel cylindrical retractor for stereotactic procedures.
  • To provide a reliable method for exposing deep intracranial targets.
  • To serve as a reference structure for computer-assisted lesion removal.

Main Methods:

  • A cylindrical retractor was designed and attached to a standard stereotaxic frame.
  • The retractor was utilized to create a surgical corridor for deep-seated lesions.

Related Experiment Videos

  • Computerized tomography (CT) and magnetic resonance imaging (MRI) were used for stereotactic definition of lesions.

    • Main Results:

    • The retractor successfully provided a route for stereotactic procedures.
    • It offered adequate exposure of the target area.
    • It served as an effective reference structure for computer-assisted removal of intracranial lesions.

    Conclusions:

    • The described cylindrical retractor is a valuable tool for stereotactic neurosurgery.
    • It facilitates the precise and computer-assisted removal of deep-seated intracranial lesions.
    • This device improves the safety and efficacy of image-guided neurosurgical interventions.
