Endoscopic Tool Manipulation Envelope Classifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic surgery poses challenges in preventing injuries to patients due to errors or improper manipulation of endoscopic tools within an intrabody cavity, and in improving the ergonomic positioning of operators to reduce fatigue and errors.
Innovation Solution
A computer-implemented method and system that utilize a classifier to analyze indications of instructions for endoscopic tool manipulation, classifying them into an envelope that restricts inappropriate manipulation. This envelope is computed based on previously obtained indications from similar procedures, guiding the surgical controller to prevent inappropriate manipulations and providing haptic feedback for safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the physician directly hand-holds and controls the tools in traditional surgery, then direct control and tactile feedback are achieved, but the surgical procedure cannot be performed remotely through indirect manipulation
Solution Approach 1:
The patent introduces a surgical robot system as an intermediary between the physician and the surgical field. The robot includes a controller that receives manipulation inputs from the physician and automatically executes precise movements of endoscopic tools within the intrabody cavity, enabling remote operation while maintaining control precision.
2Adaptability or versatility
If the physician remotely manipulates endoscopic tools without constraints, then operational flexibility is maintained, but inappropriate manipulation may cause patient injury
Solution Approach 1:
The system pre-defines safe manipulation envelopes based on anatomical knowledge and surgical best practices before the procedure begins. These envelopes establish predetermined safe zones and movement boundaries for endoscopic tools, allowing the physician to operate flexibly within these pre-established safety constraints without risking patient injury.
Solution Approach 2:
The system continuously monitors the position and manipulation of endoscopic tools in real-time, comparing actual movements against the pre-defined safe envelopes. When manipulation approaches or exceeds safety boundaries, the system provides feedback to the physician through the controller, alerting them to adjust their manipulation to remain within safe zones.
3Device complexity
If the physician operates without ergonomic support, then operational simplicity is maintained, but fatigue and errors increase during prolonged procedures
Solution Approach 1:
The robot system automatically performs complex manipulation tasks and maintains optimal tool positioning within the intrabody cavity, reducing the physical and cognitive burden on the physician. The system self-adjusts to maintain safe and effective manipulation patterns, allowing the physician to operate with less fatigue even during prolonged procedures.

AI summary
There is provided a computer implemented method of providing a surgical controller with instructions to restrict a manipulation of an endoscopic tool during an endoscopic medical procedure in an intrabody cavity, comprising: inputting into classifier(s), indication(s) of instructions for manipulation of the endoscopic tool outputted by sensor(s), classifying by the classifier(s), the indication of instructions into an envelope defining a volume that restricts therein manipulation of the endoscopic tool, wherein the classifier(s) classifies the envelope based on previously obtained indications of instructions for manipulation of endoscopic tools during other endoscopic medical procedures performed in intrabody cavities of other patients, analyzing the indication of instructions for manipulation of the endoscopic tool according to the envelope to determine when the instructions are for manipulation of the endoscopic tool externally to the envelop, and providing the surgical controller with an indication of inappropriate manipulation according to the analysis.
