Summary
Robotic surgery in otoneurosurgery enhances precision. Force-controlled robotic milling and ultrasound navigation reduce heat damage and may replace CT scans for planning surgical procedures.
Area of Science:
- Neurosurgery
- Robotics
- Medical Imaging
Background:
- Otoneurosurgery requires high precision for implant placement.
- Current methods may have limitations in accuracy and safety.
- Robotic assistance offers potential for improved surgical outcomes.
Purpose of the Study:
- To evaluate the feasibility of robotic milling for otoneurosurgical implant cavities.
- To assess the impact of force feedback on milling-induced heat.
- To explore the use of ultrasound for pre-operative planning and navigation.
Main Methods:
- A Stäubli RX 130 serial robot was used to mill implant cavities in human skull specimens.
- Force, momentum, and temperature data were collected during milling.
- Ultrasound probes were employed for skull bone thickness measurement and 3D scanning.
- Force feedback was utilized to control milling speed.
Main Results:
- An exact implant cavity was successfully milled using the robot.
- Force-controlled milling significantly reduced heat production compared to uncontrolled milling.
- 3D ultrasound scanning enabled planning of robot drilling tasks via local navigation.
Conclusions:
- Robotic milling with force feedback is a viable technique for otoneurosurgery.
- This method reduces heat damage to surrounding tissues.
- Ultrasound navigation presents a potential alternative to CT scanning for surgical planning.
