Surgical Microscope Surroundings Camera Composite View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical microscopes limit the surgeon's ability to view both the intervention area and its surroundings simultaneously, leading to strain and potential unintentional errors due to the need to constantly switch between different viewing modalities, which can result in decreased hand-eye coordination and increased mental stress during surgical procedures.
Innovation Solution
A surgical assistance system equipped with a movable microscope head featuring a camera system that includes a surroundings camera attached to the microscope head, allowing for a combined view of the magnified intervention area and its environment to be displayed centrally, reducing the need for head position changes and improving coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the surgeon uses a surgical microscope with high magnification to view the intervention area, then the visualization precision of the intervention area is improved, but the field of view is reduced making it difficult to see surrounding areas
Solution Approach 1:
The field of view is segmented into multiple zones: a central high-magnification zone for the intervention area and peripheral low-magnification zones for surrounding areas. The display device shows the microscope image in the center with surrounding area images in peripheral regions, allowing simultaneous visualization of both detailed intervention area and broader context without requiring the surgeon to switch between different viewing modes
Solution Approach 2:
The system transitions from a single two-dimensional microscope view to a composite multi-dimensional display that combines the central microscope image with peripheral surrounding area images. This creates a panoramic visual field that encompasses both the detailed intervention area and the broader surgical context in a single integrated view
2Loss of information
If the surgeon constantly switches between microscope picture and surrounding area view, then the awareness of intervention area and surroundings is improved, but the mental stress and time loss increase
Solution Approach 1:
The system merges the microscope image and the surrounding area image into a single composite display shown on the display device. The microscope picture is displayed in the center while surrounding area pictures are displayed in peripheral zones, creating an integrated panoramic view that provides continuous awareness of both the intervention area and surroundings without requiring the surgeon to switch between separate views
Solution Approach 2:
The display device continuously shows the composite image with both central and peripheral views simultaneously maintained, eliminating the need for the surgeon to repeatedly switch between different viewing modes. This continuous presentation of integrated information reduces mental stress and prevents loss of time associated with frequent view switching
3Ease of operation
If the OR monitor is arranged to provide good view of both microscope picture and intervention area, then the surgeon's view quality is improved, but the flexibility of arrangement is reduced
Solution Approach 1:
The display device serves multiple functions simultaneously: it displays the high-magnification microscope picture for detailed work, provides a panoramic view including surrounding areas for spatial orientation, and can be positioned at various locations in the operating room without compromising view quality. The composite display format makes the system adaptable to different surgical workflows and room layouts
4Measurement precision
If the microscope head is positioned to block direct view of patient, then the surgeon gets good view of microscope picture, but the direct view of intervention area is lost
Solution Approach 1:
The system uses an intermediary camera system mounted on the microscope head to capture images of the surrounding area, including the patient and intervention area. These intermediary images are then displayed in the peripheral zones of the display device, providing the surgeon with indirect visual access to the broader surgical context while maintaining the magnified view through the microscope for detailed work

AI summary
A surgical intervention system, image display method, storage medium, and sterile space. The system includes a microscope having a movable head with an optical system that magnifies a targeted area and produces a digital image with an image unit. A microscope arm connects to a base that adjusts a position and/or orientation of the microscope head. A control unit processes the image and controls a display device. The microscope further includes a camera system with a surroundings camera arranged at the microscope head. A field of view of the surroundings camera includes the field of view of the optical system to capture the targeted area and an environment around the targeted area and provide a surroundings image. The control device processes the surroundings image and generates a combined view with the microscope image and the surroundings image. The control device outputs the combined view on the display device.
