Solution Overview

Problem

Current endoscopic surgery techniques, particularly in kidney stone removal, face challenges such as radiation exposure for doctors and patients, operator fatigue, and the risk of medical accidents due to limited endoscope flexibility and precision, especially in complex internal structures.

Innovation Solution

An autonomous endoscopic system that uses kinematic driving records to autonomously navigate and position the endoscope, reducing operator fatigue and improving precision by allowing the endoscope to drive to specific locations based on previous records, thereby reducing operation time and improving surgical stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If autonomous driving records are stored and reused for endoscope navigation, then operation time is reduced and productivity is improved, but device complexity increases due to the need for recording and playback systems

Engineering Contradiction:
Improveoperation timeVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by recording the driving trajectory and operational data during the first manual procedure. This recorded information is then reused as a template for subsequent procedures, eliminating the need to manually repeat the same navigation path and reducing operation time while maintaining consistent surgical outcomes

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a digital copy of the driving record from the first procedure and uses this copy to guide the endoscope in subsequent procedures. This copying approach allows the system to replicate successful navigation paths without requiring the operator to manually recreate them, thereby improving productivity while the complexity is confined to the recording and playback mechanism

Inventive Principle:
Principle #26Copying

2Measurement precision

If radiodiagnostic equipment is continuously used to check endoscope position, then measurement precision is improved, but harmful radiation exposure increases for doctors and patients

Engineering Contradiction:
Improveposition accuracyVSAvoidradiation exposure
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary position detection using radiodiagnostic equipment only during the first procedure to establish the driving record. Subsequent procedures use this pre-recorded trajectory information for navigation, eliminating the need for continuous radiation exposure while maintaining the ability to achieve precise positioning based on the stored spatial data

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system extracts the essential positional and navigational information from the radiodiagnostic images during the first procedure and stores it as a driving record. This extraction allows the system to operate without continuous radiodiagnostic equipment in subsequent procedures, removing the harmful radiation exposure while preserving the measurement precision achieved during the initial setup

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If operators manually control the endoscope for long periods, then ease of operation is maintained, but operator fatigue increases and reliability decreases

Engineering Contradiction:
Improvemanual controlVSAvoidsurgical precision
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables the endoscope to navigate autonomously by playing back the stored driving record, which automatically controls the endoscope's movement along the recorded trajectory. This self-service capability eliminates the need for continuous manual manipulation, reducing operator fatigue and maintaining consistent surgical precision without relying on human endurance

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces the mechanical manual control system with an automated control system that uses pre-recorded driving data to guide the endoscope. This substitution transfers the control burden from the operator to the automated system, maintaining ease of operation through simple activation while significantly improving reliability by eliminating fatigue-related errors

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