Multi-view Display System for Surgical Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems in medical surgery environments, such as head-mounted displays and through-the-lens projection systems, cause ergonomic issues like head posture compromise, binocular rivalry, and visual discomfort due to the need for frequent head movement and interocular differences in image stimulation, leading to fatigue, disorientation, and impaired attention.
Innovation Solution
A multi-view system with a display device positioned away from direct view, allowing users to switch between normal and magnified views by eye movement while maintaining ergonomic posture, using a frame support and transparent member to minimize binocular rivalry and reduce head movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a computer monitor is placed close to the patient for viewing magnified video content, then the doctor can view the video content, but the doctor must frequently look back and forth between the monitor and the patient, causing head posture compromise and fatigue
Solution Approach 1:
The patent combines the video display function with the direct viewing path by positioning the display device in the user's periphery vision rather than requiring separate viewing. This merging allows the doctor to see both the patient and video content simultaneously without head movement, resolving the contradiction between video visibility and posture comfort.
Solution Approach 2:
The patent transitions from a traditional front-facing display requiring horizontal head movement to a periphery-positioned display that utilizes the user's peripheral vision dimension. This dimensional change allows simultaneous access to both direct view and video content without compromising head posture.
2Loss of information
If a heads-up display is used to provide video view, then the user can see video content, but the user's entire field of view is taken up by the video displays, disrupting the ability to function physically in the operating field
Solution Approach 1:
The patent applies local quality by providing video information only in the user's periphery vision rather than occupying the entire field of view. This localized approach allows the central vision to remain dedicated to direct viewing and physical manipulation, maintaining adaptability while providing video visibility.
3Loss of information
If through the lens projection systems are used to display video content, then the user can see both direct field and enhanced view, but the obstruction of the normal view reduces visual accuracy required in surgery
Solution Approach 1:
The patent segments the visual field into distinct regions: direct central vision for high-accuracy viewing and periphery vision for video content. This segmentation prevents the video display from obstructing the normal view, maintaining visual accuracy while providing video visibility.

AI summary
The present invention provides a multi-view system containing a means for retaining multi-view system on a user's head. A frame support is pivotally connected to the means for retaining multi-view system. At least one display device, such as an LCD, is hingedly connected to the frame support. The display device is positioned away from the direct view of the user's eyes. In a preferred embodiment, the display device is positioned at least 3 degrees away from the direct view of the user's eyes. In operation, the user can see objects in direct view and the display device by moving the eyes to provide direct view and display device view capability.
