Solution Overview

Problem

The risk of inadvertently collapsing a kidney during the aspiration of kidney stones using an extraction catheter with a large vacuum lumen, which can rapidly evacuate the kidney and potentially cause damage, is a significant challenge in existing endoscopic procedures.

Innovation Solution

An endoscopic system equipped with an image processor and video display that determines a reference value for image characteristics, compares it with real-time measurements, and activates warnings or reduces suction to mitigate the risk of kidney collapse by monitoring the proximity of the endoscope to the tissue wall and adjusting suction levels accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a large vacuum lumen is used for rapid evacuation of kidney stones, then productivity is improved, but the risk of kidney collapse increases

Engineering Contradiction:
Improveevacuation speedVSAvoidkidney collapse risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors the kidney's structural integrity through imaging during aspiration and provides real-time feedback to the operator. When signs of kidney collapse are detected, the system alerts the operator to reduce or stop suction, thereby preventing the harmful effect while maintaining efficient stone evacuation capability

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system establishes baseline imaging of the kidney structure before initiating aspiration. This preliminary documentation allows the operator to compare real-time images against the baseline and detect early signs of collapse before significant damage occurs, enabling preventive action

Inventive Principle:
Principle #10Preliminary action

2Productivity

If suction is applied to remove kidney stones, then productivity is improved, but the risk of tissue damage increases

Engineering Contradiction:
Improvestone removal rateVSAvoidtissue damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

Real-time imaging feedback allows the operator to adjust suction levels dynamically. The system monitors tissue response to suction and provides continuous information to prevent excessive suction that could cause tissue damage while maintaining effective stone removal

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables dynamic adjustment of suction parameters based on real-time conditions. The operator can modulate suction strength according to the specific anatomical structures being treated and the immediate response observed in the images, optimizing the balance between removal efficiency and tissue safety

Inventive Principle:
Principle #15Dynamics

AI summary

A system and method for mitigating kidney collapse includes determining a reference value for some characteristic of a video image transmitted from an endoscope device, measuring how a new value of the same characteristic of the video image compares to the reference value, and querying the device condition to determine whether the device condition is such that there is a potential for kidney collapse. Optionally, the system and method include activating a warning related to the potential for kidney collapse and automatically reducing suction to mitigate the potential for kidney collapse.
