Summary
A custom robot system with optical navigation achieved accurate skull base biopsies in phantom studies. This robot-assisted needle biopsy system demonstrated efficiency, reliability, and safety for surgical procedures.
Area of Science:
- Neurosurgery
- Robotics
- Medical Imaging
Background:
- Skull base biopsies are crucial for diagnosing tumors.
- Traditional biopsy methods can be challenging due to complex anatomy.
- Advancements in robotic surgery offer potential for improved precision.
Purpose of the Study:
- To assess the feasibility and accuracy of a novel robot system for skull base biopsy.
- To evaluate optical cone beam computed tomography (CBCT)-based navigation in robot-assisted procedures.
- To determine the precision of robot-guided needle insertion for targeted biopsies.
Main Methods:
- A custom five degrees of freedom robot system was utilized.
- Optical navigation guided the automatic insertion of a 14-gauge needle.
- Phantom skull models were used for accuracy assessment.
- Image fusion verified the accuracy of needle placement and deviation.
Main Results:
- All 20 robotic interventions were successfully completed.
- Mean needle tip deviation was significantly low (0.56 ± 0.22 mm via navigation).
- Angular deviations were minimal, indicating high directional accuracy.
Conclusions:
- The robot system is efficient, reliable, and safe for skull base biopsy.
- Navigation accuracy is a critical determinant of success in robotic surgical procedures.
- This technology shows promise for enhancing precision in skull base interventions.
