Solution Overview

Problem

Existing endoscopic procedures face challenges in accurately guiding medical devices to their intended destinations, particularly in procedures like ERCP, where precise orientation is crucial for success.

Innovation Solution

An image processing device connected to an endoscope's image capturing unit estimates the landing zone of a medical device by processing sensor data and overlaying a visual indication on the image stream, assisting the operator in achieving precise placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If visual guidance is provided to assist medical device placement, then procedure accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvelanding zone estimation accuracyVSAvoidimage processing device complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an image processing device as an intermediary system that receives sensor data from the endoscope, processes this data to estimate the landing zone, and displays visual guidance to the operator. This intermediary layer provides the complex processing functionality without directly modifying the endoscope or medical device, thus improving accuracy while managing complexity through system architecture separation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If real-time visual feedback is provided during the procedure, then procedure efficiency is improved, but information processing requirements increase

Engineering Contradiction:
Improveprocedure efficiencyVSAvoidsensor data processing load
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent extracts only the essential information needed for landing zone estimation from the sensor data, rather than processing all available data in real-time. The image processing device selectively processes sensor data to generate visual guidance indicators, reducing the information processing load while maintaining real-time feedback capability and procedure efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If multiple sensors are integrated into the endoscope, then measurement capability is improved, but ease of operation decreases

Engineering Contradiction:
Improvespatial position measurementVSAvoidendoscope operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements self-service by having the image processing device automatically process sensor data and generate visual guidance indicators without requiring manual intervention from the operator. The system autonomously estimates the landing zone and provides real-time visual feedback, improving measurement capability while maintaining ease of operation as the operator simply follows the visual guidance.

Inventive Principle:
Principle #25Self-service
