Summary
A new virtual reality endoscopic system improved suturing performance by enhancing visualization and depth perception. This system offers better control for surgeons during minimally invasive procedures.
Area of Science:
- Minimally Invasive Surgery
- Surgical Simulation
- Virtual Reality Applications
Background:
- Endoscopic surgery requires informative visualization regardless of surgical situation.
- Current endoscopic systems face challenges with degrees of freedom in manipulation.
- Virtual reality (VR) offers potential for enhanced surgical views.
Purpose of the Study:
- To develop and test an endoscopic pseudo-viewpoint alternation system.
- To provide an arbitrary viewpoint for a region of interest using VR.
- To improve image presentation irrespective of surgical conditions.
Main Methods:
- A VR system was tested with surgical experts and trainees.
- Participants performed a right-to-left suturing task.
- Task outcomes were compared with and without the VR system.
Main Results:
- Total error was reduced by 0.37 mm with the VR system.
- Experts showed greater improvement than novices.
- The system improved depth perception and marker aiming.
Conclusions:
- The VR endoscopic display system enhanced suturing performance.
- Viewpoint alternation improved visualization and control.
- The proposed method offers improved user visualization and control in endoscopic surgery.
