Summary
A new Digital Twin Visual Assistance (DTVA) system reduces master-slave latency in robot-assisted telesurgery. DTVA improves precision and efficiency, demonstrating clinical feasibility for remote surgical procedures.
Area of Science:
- Robotics
- Surgical Technology
- Medical Imaging
Background:
- Master-slave latency poses a significant challenge in robot-assisted telesurgery.
- Effective latency mitigation is crucial for safe and precise remote surgical interventions.
Purpose of the Study:
- To introduce and evaluate a Digital Twin Visual Assistance (DTVA) system for mitigating latency in telesurgery.
- To assess the impact of DTVA on spatial precision, task completion time, and operator workload.
Main Methods:
- Development of a DTVA system integrating parametric 3D modeling and virtual endoscopic visualization.
- Evaluation on a distributed robotic platform with programmable latency emulation.
- Clinical validation via teleoperated radical nephrectomy.
Main Results:
- DTVA maintained spatial precision within 2mm error.
- Peg-transfer completion time reduced by 13.6% under 900ms latency.
- Operator workload decreased by 27.2% and procedures were successful under 300ms latency.
Conclusions:
- The DTVA system effectively mitigates latency effects in robot-assisted telesurgery.
- Preliminary clinical validation confirms the feasibility and safety of DTVA for telesurgical procedures.
