Endoscopic Off-Screen Bleeding and Incision-Motion Alerts During Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laparoscopic surgery systems lack the ability to digitally maneuver the field of view of the endoscopic image, requiring physical manipulation of the endoscope or lenses to adjust magnification and perspective, which can be cumbersome and risky.
Innovation Solution
A system comprising an endoscope with a wide-angle lens, a camera, and a computer program that allows digital manipulation of the field of view through software, enabling selection and adjustment of the image without physical movement of the endoscope or lenses, and providing features like digital zoom, warnings for specific events, and automatic maneuvering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical manipulation of the endoscope or lenses is used to adjust magnification and perspective, then the field of view can be changed, but the risk of accidental contact with tools or body parts increases and the operation becomes cumbersome
Solution Approach 1:
The patent replaces the mechanical system of physically moving the endoscope or lenses with a digital image processing system. The computer program processes the captured image to provide digital zoom, pan, and perspective adjustments, eliminating the need for mechanical manipulation of the endoscope position and thereby reducing the risk of accidental contact with surgical tools or body parts.
Solution Approach 2:
The patent creates a digital copy of the endoscopic image and manipulates this copy through software algorithms rather than manipulating the physical endoscope. The image processing system generates virtual views with different magnifications and perspectives from the captured image, allowing field of view adjustment without physical movement of the endoscope.
2Adaptability or versatility
If physical manipulation of the endoscope is used to adjust the view, then magnification and perspective can be changed, but the system complexity and risk of contact increase
Solution Approach 1:
The patent substitutes complex mechanical manipulation systems with a software-based image processing system. The computer program provides versatile adjustments including digital zoom, panning, and perspective changes through image processing algorithms, achieving the same adaptability without the mechanical complexity and associated risks.
3Productivity
If the endoscope is physically moved to provide overview or close-up views, then the field of view changes, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces time-consuming physical repositioning of the endoscope with instantaneous digital image processing. The computer program can rapidly switch between overview and close-up views by processing the captured image, providing both speed and ease of operation that cannot be achieved through mechanical manipulation.

AI summary
An image of a field of view is captured by the endoscope and a portion of the image is displayed on a display. A popup image is generated and displayed upon image analysis identification of an occurrence of bleeding or motion of edges of an incision that is within the field of view, but outside the portion of the field of view displayed on the display.
