Summary
This study developed a novel mixed reality (MR) temporal bone simulator by combining haptic soft tissue simulation with 3D printed bone models. The system successfully integrates a surgical drill for realistic training, demonstrating proof of concept.
Area of Science:
- Medical Simulation
- Surgical Training Technologies
- Mixed Reality (MR) Applications
Background:
- Current haptic simulators struggle with realistic contact forces.
- 3D printed bone models lack soft tissue representation.
- A novel approach combines haptic and 3D printed simulations.
Purpose of the Study:
- To develop a novel mixed reality (MR) simulation for temporal bone surgery training.
- To address the mechanical integration of a haptic device with an otic drill.
- To enable realistic simulation of soft tissue interaction during drilling.
Main Methods:
- Developed custom software to reposition haptic interaction to the drill tip.
- Created a custom fitting for the otic drill with weight offset via haptic device.
- Tested system robustness and stability using a mixed reality model with virtual soft tissue forces.
Main Results:
- Effectiveness of gravity cancellation was demonstrated.
- The system showed excellent performance with random inputs and during transitions between real and virtual components.
- No registration issues were observed at model boundaries.
Conclusions:
- The developed system serves as a proof of concept for a novel mixed reality temporal bone simulator.
- This technology advances surgical simulation by integrating haptic feedback and realistic models.
- Further development stages are planned for this innovative training tool.
