Area of Science:

Neurosurgery
Robotics
Medical Imaging

Background:

Developing advanced navigation systems is crucial for improving precision in neurosurgical bone drilling procedures.
Current methods require enhanced assistance throughout the entire bone drilling process.

Purpose of the Study:

To develop a neurosurgical robotic arm drilling navigation system.
To provide comprehensive assistance during the complete bone drilling process.

Main Methods:

Integrated robotic and surgical navigation with 3D medical imaging for surgical planning.
Implemented automatic bone drilling control with a drill-through prevention mechanism.
Conducted three experimental validation studies.

Main Results:

Achieved an average robotic arm positioning error of 0.502 ± 0.069 mm.
Demonstrated high correlation (0.975) between automatic and manual path planning.
The automatic drilling control system showed 0.00% unstopped cases and 70.53% non-drilled-through cases, significantly outperforming control groups.

Conclusions:

The developed neurosurgical robotic arm drilling navigation system shows potential utility.
The system enhances safety and accuracy in neurosurgical bone drilling.
