Solution Overview
Problem
Conventional surgical site temperature control during procedures like laser lithotripsy lacks precision and speed, often leading to thermal damage due to manual adjustments and potential compromises in therapy efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual temperature adjustment is used, then the system is simple to operate, but temperature control precision and speed are insufficient
Solution Approach 1:
The system implements automatic feedback control by detecting tissue whitening through imaging sensors and using this information to adjust laser output parameters in real-time, thereby achieving precise temperature control without manual intervention
Solution Approach 2:
The system performs self-regulation of temperature by automatically detecting thermal damage indicators (tissue whitening) and adjusting its own operating parameters, eliminating the need for external manual control while maintaining high precision
2Reliability
If laser output intensity is reduced to control temperature, then thermal damage is prevented, but therapy efficiency is compromised
Solution Approach 1:
The system dynamically adjusts laser output parameters based on real-time tissue response detection, allowing the laser intensity to vary continuously to maintain optimal balance between therapy efficiency and tissue safety
Solution Approach 2:
The system changes multiple laser parameters (power, pulse duration, frequency) in combination rather than simply reducing output intensity, thereby maintaining therapeutic effectiveness while controlling thermal accumulation through coordinated parameter optimization
3Productivity
If high intensity laser output is used, then therapy efficiency is improved, but thermal damage risk increases
Solution Approach 1:
The system uses real-time detection of tissue whitening as feedback to monitor thermal accumulation and automatically adjusts laser parameters to prevent thermal damage while maintaining high therapy efficiency
Solution Approach 2:
The system detects early signs of thermal damage (tissue whitening) before actual thermal damage occurs and takes preliminary corrective action by adjusting laser parameters, thereby preventing harm while maintaining treatment effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach provides more precise and faster temperature control, reducing the risk of thermal damage and maintaining therapy efficacy by automatically responding to tissue whitening indicators.
Implementation Method 1
tissue whitening (tissue blanching) that can be detected from images or video frames of at least a portion of the surgical site
Implementation Method 2
endoscopic surgical device controllably coupled to a medical instrument (e.g., a laser system) and configured to deliver energy (e.g., laser energy) to a surgical site
Implementation Method 3
Heat buildup is a potentially hazardous consequence of laser treatment of an anatomical or calculi target

AI summary
Systems, devices, and methods for automatic control of surgical site temperature during an endoscopic procedure are disclosed. An exemplary endoscopic surgical system comprises an endoscopic surgical device controllably coupled to a medical instrument to deliver energy to a surgical site during a procedure, an imaging sensor to generate images or video frames of at least a portion of the surgical site during the procedure, and a controller circuit to analyze the generated images or video frames to determine whether a degree of heat built up in a first target at the surgical site exceeds a predetermined threshold. Based on such determination, the controller circuit can determine whether to adjust at least one operating parameter associated with the endoscopic surgical system to achieve or maintain a treatment effect of a different second target at the surgical site while avoid damaging the first target during the procedure.
