Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical imaging systems are limited in recognizing and conveying information about concealed structures, physical contours, and dimensions within a three-dimensional space, leading to uncertainty in surgical procedures, which can result in inadequate surgical outcomes due to the inability to accurately locate critical structures like ureters, arteries, and nerves.
Innovation Solution
A surgical visualization system that incorporates a light emitter to emit structured electromagnetic radiation, an image sensor to receive reflected radiation, and a control circuit to generate images, determine surgical actions, and provide user recommendations based on comparisons with baseline actions, enhancing the clinician's ability to identify and avoid critical structures during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional imaging systems are used to view the surgical site, then the system is simple and easy to operate, but the system cannot recognize or convey information about concealed structures, physical contours, and dimensions within a three-dimensional space
Solution Approach 1:
The patent applies structured light projection to transform two-dimensional image data into three-dimensional spatial information. By projecting known light patterns onto the surgical site and analyzing the reflected light from multiple angles, the system reconstructs three-dimensional contours, depths, and spatial relationships of concealed anatomical structures, enabling clinicians to visualize hidden features without adding excessive system complexity
Solution Approach 2:
The patent introduces structured light patterns as an intermediary between the imaging system and the concealed structures. These projected light patterns serve as a mediator that interacts with the three-dimensional surface of the surgical site, encoding spatial information that can then be decoded by the imaging system to reveal concealed anatomical features
2Measurement precision
If conventional imaging systems are used, then the device complexity is low, but the measurement precision of surgical site contours and dimensions is insufficient
Solution Approach 1:
The system uses structured light projection to capture three-dimensional surface topology data, transforming conventional two-dimensional imaging into volumetric measurement. This enables precise quantification of surgical site contours, depths, and spatial relationships by analyzing the deformation of projected light patterns across the tissue surface
Solution Approach 2:
The patent changes the optical parameters of the imaging system by introducing structured light patterns with specific spatial frequencies and intensities. By varying these light parameters and analyzing the reflected patterns, the system achieves high-precision measurement of surface contours and dimensions through optical encoding rather than mechanical measurement
3Reliability
If conventional imaging systems are used, then the system is simple, but the reliability of surgical outcomes is reduced due to inability to locate critical structures
Solution Approach 1:
The system reconstructs three-dimensional anatomical models from structured light data, enabling clinicians to identify and locate critical structures such as blood vessels, nerves, and tissue boundaries with enhanced spatial awareness. This three-dimensional visualization improves surgical decision-making and reduces the risk of damaging critical structures
Solution Approach 2:
The system provides real-time feedback by continuously monitoring the surgical site and updating the three-dimensional model during the procedure. This dynamic feedback loop allows clinicians to adjust their surgical approach based on evolving anatomical information, improving the reliability of surgical outcomes through informed decision-making

AI summary
Various surgical systems configured to analyze surgical procedure trends are disclosed. The surgical systems can further be configured to provide recommendations and/or adjust control algorithms executed by the surgical systems according to the identified trends. The identified trends can be utilized to determine a baseline or recommended action to be performed at a decision point in a surgical procedure. The surgical systems can be configured to provide preoperative, intraoperative, or postoperative feedback to users based on their decisions at the decision points relative to the determined baseline or recommended actions.
