Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional endoscopic laser therapy is performed without continuous monitoring, then the procedure can be completed, but tissue composition cannot be accurately identified leading to inefficient targeting and exposure of non-treatment tissue to laser irradiation
Solution Approach 1:
The system employs a feedback analyzer that receives reflected electromagnetic radiation signals from the target tissue, determines tissue composition and distance based on these signals, and provides real-time feedback to the controller. This feedback loop enables continuous monitoring and automatic adjustment of laser therapy parameters, ensuring accurate tissue identification and preventing irradiation of non-treatment tissue.
Solution Approach 2:
The system performs preliminary identification of tissue composition and distance before laser irradiation is applied. By analyzing reflected electromagnetic radiation signals in advance, the system determines whether the target is treatment or non-treatment tissue, allowing the controller to adjust laser parameters or prevent irradiation before harmful exposure occurs.
2Productivity
If manual monitoring of tissue composition is performed, then the procedure can be completed, but the process is time-consuming and reduces procedure efficiency
Solution Approach 1:
The system performs automatic identification of tissue composition and distance without requiring manual intervention. The feedback analyzer and controller work autonomously to analyze reflected signals, determine tissue properties, and adjust laser parameters, eliminating time-consuming manual monitoring steps and improving procedure efficiency.
Solution Approach 2:
The system replaces manual mechanical monitoring with automated electromagnetic radiation analysis. By using optical/electromagnetic fields to detect tissue composition and distance, the system eliminates the need for time-consuming manual assessment, enabling real-time automated control of laser therapy parameters.
3Measurement precision
If laser therapy is performed without distance control, then the procedure can be completed, but accurate targeting of treatment structures cannot be achieved
Solution Approach 1:
The system uses feedback from reflected electromagnetic radiation signals to continuously monitor the distance between the endoscope and target tissue. This distance information is fed back to the controller, which adjusts laser therapy parameters accordingly, ensuring accurate targeting and maintaining optimal treatment distance throughout the procedure.

AI summary
Systems, devices, and methods for determining a distance between a distal end of an endoscope and a target during an endoscopic procedure are disclosed. A surgical laser feedback control system comprises a feedback analyzer and a controller. The feedback analyzer can receive at least two reflected signals from a target in response to electromagnetic radiation directed at the target. The at least two reflected signals correspond to respective different distances between a distal end of a device of a surgical laser system and the target. The feedback analyzer can determine a distance between the distal end of the device of the surgical laser system and the target based on the at least two reflected signals. The controller can generate a control signal to the surgical laser system to perform a predetermined operation based on the determined distance.
