Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic laser therapy lacks accuracy in recognizing and continuously monitoring tissue composition during procedures, leading to inefficient and potentially harmful exposure of non-target tissues to laser irradiation, as manual recognition is limited by visual access and requires biopsy for in vitro analysis.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual recognition is used to identify target tissues, then the procedure can be performed with simple equipment, but the accuracy and reliability of target identification is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where spectroscopic data is continuously collected from the target tissue and fed back to the control system. The controller analyzes the spectral data and automatically adjusts laser parameters accordingly, creating a closed-loop control system that continuously optimizes target identification and treatment based on real-time tissue composition analysis.
Solution Approach 2:
The patent replaces manual visual recognition with an automated spectroscopic analysis system. Instead of relying on the operator's visual assessment, the system uses optical spectroscopy to objectively characterize tissue composition, thereby substituting the mechanical/visual process with an optical and computational process that provides more precise and reliable identification.
2Object-affected harmful factors
If conventional laser therapy is used without real-time monitoring, then the treatment process is simple and fast, but non-target tissues are exposed to harmful laser irradiation
Solution Approach 1:
The system continuously monitors the tissue composition during laser treatment using spectroscopy and feeds this information back to the controller. The controller uses this real-time feedback to dynamically adjust or terminate laser irradiation when non-target tissues are detected, preventing harmful exposure while maintaining treatment efficiency through automated decision-making.
Solution Approach 2:
The system performs preliminary spectroscopic analysis of the target tissue before initiating laser treatment. By characterizing the tissue composition in advance and continuously during the procedure, the system can proactively identify and protect non-target tissues from laser irradiation before damage occurs, rather than reacting after harm has been inflicted.
3Measurement precision
If biopsy is performed for in vitro analysis, then the composition analysis can be performed with standard laboratory equipment, but the procedure time and loss of time are increased
Solution Approach 1:
The patent performs composition analysis in real-time during the surgical procedure using in vivo spectroscopy, eliminating the need for subsequent biopsy and laboratory analysis. The system continuously characterizes tissue composition at the time of treatment, providing immediate feedback that accelerates the overall procedure by removing the time-consuming biopsy and lab processing steps.
Solution Approach 2:
The patent replaces the mechanical biopsy process with non-invasive optical spectroscopy. Instead of physically removing tissue samples for laboratory analysis, the system uses light-based spectroscopic techniques to directly analyze tissue composition in vivo, substituting a complex mechanical and temporal process with a faster, non-invasive optical measurement approach.
4Adaptability or versatility
If laser settings are fixed, then the equipment operation is simple, but the adaptability to different tissue compositions is insufficient
Solution Approach 1:
The system automatically adjusts laser settings based on real-time spectroscopic feedback from the target tissue. The controller continuously monitors tissue composition and autonomously modifies laser parameters such as power, pulse duration, and wavelength to optimize treatment effectiveness for different tissue types, eliminating the need for manual operator intervention while maintaining high adaptability.
Solution Approach 2:
The patent transitions from fixed, static laser settings to dynamic, real-time adjusted parameters. The laser system automatically adapts its operating characteristics based on continuous spectroscopic monitoring of tissue composition, allowing the system to respond flexibly to varying tissue properties without requiring complex manual controls from the operator.
