Solution Overview

Problem

Existing medical systems lack a reliable and precise method to determine the maintenance requirement of light guidance components, such as light sources, lighting cables, camera heads, and endoscopes, leading to potential suboptimal functionality or premature maintenance.

Innovation Solution

A medical system that includes a data processing unit and lighting components, which collects historical data on light intensity parameters, lighting component configurations, and external intervention parameters during medical procedures. This data is used to calculate trends and generate maintenance requirement reports if specified limits are exceeded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If maintenance is scheduled based on usage count or reprocessing cycles, then maintenance timing can be determined, but the actual maintenance requirement cannot be reliably determined leading to premature or unnecessary maintenance

Engineering Contradiction:
Improvemaintenance requirement determination accuracyVSAvoidtime for unnecessary maintenance
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system continuously monitors light intensity parameters during medical procedures and compares them against historical data and predetermined limits. This feedback mechanism allows the system to detect actual degradation of optical fibers and trigger maintenance only when necessary, replacing the conventional usage-count-based scheduling approach.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical/administrative tracking method (counting usage cycles) with an optical measurement-based system that directly monitors the functional state of the optical fibers through light intensity parameter monitoring, enabling condition-based maintenance decisions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If light intensity parameter monitoring is implemented, then maintenance requirements can be determined more accurately, but system complexity increases due to additional data collection and processing requirements

Engineering Contradiction:
Improvemaintenance requirement determination accuracyVSAvoiddata processing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The data processing unit performs multiple functions: it collects light intensity parameters, stores historical data, compares current values against limits, identifies degradation trends, and triggers maintenance alerts. This multi-functionality consolidates what would otherwise require separate systems into a single integrated unit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically monitors its own components, stores historical data, performs comparative analysis, and generates maintenance recommendations without requiring external intervention. The data processing unit serves itself by continuously self-diagnosing the optical fiber condition.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If conventional usage-based maintenance scheduling is used, then maintenance can be planned, but the actual functionality of the endoscope cannot be reliably assessed

Engineering Contradiction:
Improvemaintenance scheduling easeVSAvoidfunctionality assessment accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system provides real-time feedback on the actual functional state of the optical fibers through continuous light intensity monitoring, enabling precise assessment of functionality independent of usage history. This feedback loop allows operators to know the true condition of the endoscope components.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system monitors changes in light intensity parameters over time and uses these parameter changes to assess the degradation state of optical fibers. By tracking parameter trends rather than relying on fixed usage thresholds, the system achieves more precise functionality assessment.

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention relates to a medical system (2) and a method for determining the maintenance requirement of an optical fiber component of the medical system (2). The medical system (2) comprises a data processing unit (4) and optical fiber components (14), namely a light source (6), an optical fiber cable (8), a camera head (10), and an endoscope (12), each through which a bundle of optical fibers (15) is guided. The data processing unit (2) is configured to determine the maintenance requirement of the optical fiber components (14) by acquiring the following data during a medical procedure and storing it as historical data: a luminous intensity parameter value, an optical fiber component parameter set, and an external procedure parameter.The data processing unit (4) is further equipped to determine a trend (16) of the luminous intensity parameter from the historical data of at least two medical interventions and to generate a maintenance requirement notification (18) if a deviation exceeding a predefinable limit value can be detected in the trend (16), and to output the maintenance requirement notification (18).
