Area of Science:

Medical Robotics
Surgical Visualization
Augmented Reality

Background:

Current non-endoscopic surgical robot systems lack effective visualization tools for depth perception.
Accurate visualization is crucial for successful remote robotic surgery.

Purpose of the Study:

To develop a novel autostereoscopic surgical visualization system for robotic telesurgery.
To enhance surgical scene information and depth perception in remote operations.

Main Methods:

Integrating 3D intraoperative scene reconstruction, autostereoscopic 3D display, and augmented reality image fusion.
Utilizing preoperative medical imaging and intraoperative RGB-D camera data for scene reconstruction.
Employing an automatic marker-free registration algorithm for aligning preoperative and intraoperative data.

Main Results:

A functional prototype demonstrated high resolution (1.31mm horizontal, 0.82mm vertical) and real-time performance (33.1 FPS rendering, 20.5 FPS registration).
The system achieved comparable operational accuracy to conventional methods, with significant improvements in completion time (34.11% reduction) and path length (35.87% reduction).
User feedback indicated the system is user-friendly for both novice and expert surgeons.

Conclusions:

The proposed 3D surgical visualization system effectively provides augmented instruction and depth perception for telesurgery.
The system demonstrates accuracy and efficiency, showing great potential for advancing robotic and telesurgery applications.
