Engineering Contradiction Analysis
1Reliability
If conventional endoscopic laser therapy is used without spectroscopic feedback, then the laser can be delivered to target tissue, but accurate monitoring and automatic recognition of tissue composition is lacking, leading to potential harmful exposure of non-treatment tissues
Solution Approach 1:
The patent implements a spectroscopic feedback system that continuously monitors tissue composition during laser therapy. The feedback analyzer receives spectroscopic signals from the target tissue, automatically recognizes tissue composition, and provides real-time feedback to control laser energy delivery. This closed-loop feedback mechanism enables accurate monitoring of tissue composition and prevents harmful exposure of non-treatment tissues by adjusting laser parameters based on actual tissue characteristics.
Solution Approach 2:
The system performs automatic recognition of tissue composition through spectroscopic analysis without requiring manual intervention. The feedback analyzer automatically identifies tissue types and composition based on spectroscopic signals, enabling the system to self-adjust laser parameters according to the actual tissue being treated, thereby improving reliability and preventing harmful effects.
2Productivity
If laser energy is delivered continuously without spectroscopic feedback control, then treatment can proceed without interruption, but tissue composition changes are not detected, leading to inefficient treatment and increased energy consumption
Solution Approach 1:
The spectroscopic feedback system continuously monitors tissue composition during laser therapy and provides real-time information about treatment effectiveness. Based on the feedback signals indicating tissue composition and treatment progress, the system can dynamically adjust laser parameters to optimize treatment efficiency, reducing unnecessary energy consumption while maintaining productive treatment pace.
Solution Approach 2:
The system dynamically adjusts laser parameters based on real-time spectroscopic feedback about tissue composition. Rather than using fixed continuous laser delivery, the system adapts its energy delivery pattern according to the actual tissue characteristics detected during treatment, improving both efficiency and energy utilization.

AI summary
Systems, devices, and methods for delivering laser energy directed toward target tissue using a spectroscopic feedback. An exemplary laser feedback control system comprises a feedback analyzer to receive a signal from a target tissue using a spectroscopic sensor, and a laser controller to determine whether the received signal generally equals a first preset. If the received signal meets the first preset, the laser controller can send a control signal to a laser system to change from a first state to a second state of the first laser system. The laser system can deliver laser energy via an optical fiber towards the target tissue.
