Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vitreoretinal surgery systems do not allow convenient and quick visualization of procedures and components outside the primary surgical field of view, complicating surgical manipulations and inspections.
Innovation Solution
An auxiliary surgical field visualization system with an auxiliary surgical field camera and display that captures and displays a secondary surgical field, including the exterior of the eye and surrounding area, allowing simultaneous viewing by the surgeon and others in the operating room.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a surgical microscope is used to view the fundus through the cornea with high magnification, then the internal portion of the eye can be visualized in detail, but the exterior of the eye and surrounding area cannot be conveniently viewed
Solution Approach 1:
The visualization system is divided into two independent cameras: a primary surgical field camera for viewing the internal fundus with high magnification, and a secondary surgical field camera for viewing the exterior of the eye and surrounding area. This segmentation allows each camera to be optimized for its specific field without compromising the other, resolving the contradiction between detailed internal visualization and comprehensive external coverage.
Solution Approach 2:
The system transitions from a single-dimensional view (either internal or external) to a two-dimensional simultaneous view by adding the secondary camera. This dimensional expansion enables the surgical team to observe both the internal fundus and external structures at the same time, eliminating the need to switch between different viewing angles.
2Measurement precision
If the surgical microscope provides high magnification imaging of the fundus, then detailed view of internal structures is achieved, but procedures outside the primary surgical field cannot be conveniently viewed
Solution Approach 1:
By segmenting the visualization function into two separate cameras with different focal points, the system allows the surgical microscope to maintain its high magnification for internal structures while the secondary camera independently captures external procedures. This eliminates the operational inconvenience of switching between different viewing modes.
Solution Approach 2:
The secondary surgical field camera acts as an intermediary device that captures external procedures and components, allowing the surgical team to view these elements without requiring changes to the primary microscope setup. This intermediary solution maintains the high magnification capability while adding external visualization capability.
3Reliability
If existing vitreoretinal surgery systems are used, then internal eye structures can be visualized, but surgical components and procedures outside the primary field require complex additional setups for viewing
Solution Approach 1:
The system segments the visualization function into two dedicated cameras, each responsible for a specific field. This segmentation simplifies the overall system architecture compared to trying to modify a single microscope to provide both internal and external views, as each camera can be independently optimized and positioned.
Solution Approach 2:
Both cameras are integrated into a unified visualization system that can simultaneously display internal and external views. This multi-functional capability eliminates the need for separate, complex viewing setups for internal and external structures, thereby reducing overall system complexity while maintaining reliable visualization of all surgical fields.
4Manufacturing precision
If only the primary surgical field is viewed, then detailed internal surgery can be performed, but communication about external procedures and components becomes difficult
Solution Approach 1:
The visualization system is segmented into two independent viewing channels - one for internal fundus surgery and one for external procedures. This segmentation allows simultaneous capture of both fields, ensuring that no information about external procedures is lost while maintaining the detailed internal view necessary for precise surgery.
Solution Approach 2:
The dual-camera system enables continuous visualization of both internal and external surgical fields simultaneously. This continuity ensures that all surgical activities, whether internal or external, are continuously captured and available for communication and documentation, eliminating information loss that would occur with sequential viewing.

AI summary
An auxiliary surgical field visualization system is described, which includes an auxiliary surgical field camera, configured for acquiring an image of a field of view of a secondary surgical field, wherein the secondary surgical field includes the exterior of a patient's eye undergoing vitreoretinal surgery. The auxiliary surgical field visualization system also includes a display in electronic communication with the auxiliary surgical field camera, wherein the display is configured for receiving, from the auxiliary surgical field camera, a signal that includes the image of the field of view of the secondary surgical field, and upon receiving the signal, displaying the image of the field of view of the secondary surgical field.
