Summary
Designing user-friendly surgical robots requires considering surgeon interaction early. A new system simulates surgeon movements to inform mechanism design, improving usability.
Area of Science:
- Robotics
- Surgical Technology
- Human-Computer Interaction
Background:
- Current surgical robot development often delays usability assessment until finalization.
- This hinders the integration of surgeon-specific operational preferences into the design process.
Purpose of the Study:
- To propose and evaluate a system that incorporates surgeon operational style during the surgical robot design phase.
- To investigate the impact of surgical robot mechanism design on surgeon interaction and performance.
Main Methods:
- Development of a system featuring a master manipulator for measuring surgeon movements and a slave simulator with configurable mechanical parameters.
- Experimental use of the system with three instrument variations differing in joint spacing.
- Measurement and analysis of instrument tip trajectories during simulated surgical tasks.
Main Results:
- Distinct differences in instrument tip trajectories were observed across the tested mechanisms.
- The study demonstrated that modifications in surgical robot mechanisms directly influence surgeon operational patterns.
Conclusions:
- Surgeon operational manner is a critical factor that must be considered during the mechanical design of surgical robots.
- Integrating operator feedback early in the design cycle can lead to more user-friendly and effective surgical robotic systems.
