Brain shifts during surgery pose a challenge for navigation systems. A new method uses a silicone tube marker inserted via a thin probe to track brain movement, improving surgical navigation accuracy.

Area of Science:

  • Neurosurgery
  • Medical Devices
  • Surgical Navigation

Background:

  • Brain shifts during surgical procedures present a significant challenge for the accuracy of navigation systems.
  • Maintaining a consistent reference point is crucial for precise microsurgery.

Purpose of the Study:

  • To develop a simple and effective method to compensate for brain shifts during surgical operations.
  • To provide a reliable reference point for navigation systems in neurosurgery.

Main Methods:

  • A thin probe, covered by a silicone tube, was inserted to a target point after dural incision.
  • The probe was removed, leaving the silicone tube in place as a reference marker.
  • The silicone tube moved with the brain, continuously indicating the initial target point.

Main Results:

  • The silicone tube marker successfully tracked brain movement throughout the operation.
  • The method provided a stable reference point despite intraoperative brain deviation.
  • The technique demonstrated its utility in accommodating brain shifts.

Conclusions:

  • The developed silicone tube method is a simple yet effective solution for managing brain shifts in surgical navigation.
  • This technique enhances the reliability and accuracy of navigation systems during complex brain surgeries.
  • Further implementation can improve patient outcomes by ensuring precise surgical targeting.
