Assessment of Visual Ergonomics in Microsurgical Procedures Using Real-Time Video Processing
Overview
This study identifies key visual ergonomic challenges faced by neurosurgeons during microsurgery and evaluates a novel real-time video processing solution combining multi-camera views and instrument transparency. The proposed approach aims to enhance contextual awareness, reduce workflow interruptions, and improve surgical task performance compared to conventional microscope setups.
Background
Visual ergonomics is critical in microsurgery, where surgeons rely heavily on image guidance devices such as surgical microscopes, endoscopes, and exoscopes. Common challenges include narrow fields of view, reduced depth perception, instrument obstruction, and frequent manual adjustments that disrupt workflow. These factors increase cognitive workload and may affect surgical precision. Advanced visualization solutions are needed to address these limitations and improve surgical outcomes.
Data Highlights
The study was conducted in two parts: Part 1 involved a survey and interviews with neurosurgeons and residents to assess visual ergonomic challenges and gather feedback on proposed visualization features. Part 2 consisted of hands-on evaluation of the prototype solution using simulated surgical tasks, comparing performance against conventional microscope setups. Participants were recruited from the Microsurgery Center of Eastern Finland and included practicing neurosurgeons and residents with experience using surgical microscopes.
Key Findings
Neurosurgeons frequently encounter visual ergonomic challenges such as limited field of view, reduced depth perception, and instrument obstruction during microsurgery.
Manual adjustments of focus, magnification, and positioning in conventional microscopes interrupt surgical workflow and increase cognitive load.
The proposed solution integrates images from two cameras using projective transformation to create an expanded, single view, enhancing contextual awareness.
Instrument transparency or subtraction features help reduce visual obstruction within the operating field.
Initial user feedback indicates that the combined multi-camera visualization improves task performance and reduces workflow interruptions compared to standard microscope settings.
Clinical Implications
Implementing real-time multi-camera image processing in microsurgical visualization can enhance surgeons' spatial awareness and reduce the need for manual adjustments, potentially decreasing cognitive workload and surgical errors. This approach may improve efficiency and precision in microsurgical procedures, supporting better patient outcomes.
Conclusion
The study demonstrates that visual ergonomic challenges are significant in microsurgery and that advanced visualization solutions combining multi-camera views and instrument transparency can effectively address these issues. Further development and clinical validation may establish these technologies as valuable tools in neurosurgical practice.
