Endoscopic Surgical Analysis System for Real-Time Instrument Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic surgery poses challenges due to the complexity of learning and the high risk of errors during initial operations, as practitioners must adapt to a different visualization and instrument control paradigm, leading to potential irreversible consequences and increased morbidity.
Innovation Solution
A method and system for analyzing surgical operations via endoscopy that detects instruments and organs, determines their positioning, selects corresponding conceptual surgical steps, compares parameters, and provides real-time and retrospective feedback to improve surgical precision and reduce errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If practitioners perform endoscopic surgery during the learning phase, then surgical experience is gained, but surgical errors occur leading to irreversible consequences and increased morbidity
Solution Approach 1:
The system provides real-time feedback during endoscopic surgery by detecting instrument positions, identifying anatomical structures, and comparing actual surgical steps against the planned protocol. This immediate feedback loop allows practitioners to correct errors before they become irreversible, thereby improving surgical outcome reliability without extending the learning curve
Solution Approach 2:
The system performs preliminary analysis by pre-defining surgical protocols and expected surgical steps before the operation begins. During surgery, the system has already prepared the reference framework for comparison, enabling immediate quality assessment and error detection without delaying the surgical procedure
2Measurement precision
If endoscopic surgery is performed without real-time analysis, then surgical speed is maintained, but errors are not detected until after the operation
Solution Approach 1:
Real-time feedback is provided by continuously monitoring instrument positions and surgical actions, comparing them against the predefined protocol. This allows immediate detection and correction of deviations, ensuring high measurement precision of surgical steps without requiring post-operative analysis time
Solution Approach 2:
The system performs automated detection and comparison functions without requiring manual intervention from the surgical team. The computer automatically tracks instruments, identifies anatomical structures, and assesses surgical step quality, eliminating the need for additional observers and avoiding time loss from manual verification

AI summary
The invention concerns an analysis method for a surgical operation via endoscopy performed at an operative site in a volume located inside the body of an animal, characterized in that it comprises the steps consisting of:detecting at least one instrument (1; 2; 3) present at the operative site,detecting at least one portion of an organ (4) in the vicinity of the detected instrument (1; 2; 3),determining the positioning of the detected instrument (1; 2; 3) relative to the detected organ (4), so that the detected instrument (1; 2; 3), the detected portion of organ (4) and their relative positioning form parameters defining a detected surgical step,selecting, in a database, a conceptual surgical step corresponding to the detected surgical step from to the detected instrument (1; 2; 3), the detected portion of organ (4) and their relative positioning,comparing the parameters of the detected surgical step with the parameters defining the selected conceptual surgical step to determine the differences between these parameters, providing information on the quality of the detected surgical step on the basis of the determined differences.
