Solution Overview
Problem
Existing electrosurgical systems face challenges in quickly and reliably adapting to different tissue types during treatment, particularly when there are temporary changes or the presence of small, localized structures of varying tissue types, requiring expert knowledge to select optimal operating modes.
Innovation Solution
An electrosurgical system with a supply apparatus that detects electrical operating parameters in real-time, such as voltage and current, to identify changes in tissue type, allowing for temporary adaptation of mode parameters like voltage, current, and waveform without switching modes, ensuring optimal treatment parameters for both primary and secondary tissue types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual mode selection is used to adapt to different tissue types, then treatment effectiveness is improved, but operation complexity and time consumption increase
Solution Approach 1:
The system automatically detects tissue type and selects optimal operating modes without requiring manual intervention from the surgeon. The supply apparatus continuously monitors electrical parameters during treatment and autonomously adapts the operating mode to match the detected tissue type, making the system self-adjusting and eliminating the need for expert knowledge in mode selection.
Solution Approach 2:
The system implements real-time feedback by continuously monitoring electrical operating parameters (voltage, current, impedance) during treatment. Based on the detected parameter changes that indicate tissue type transitions, the system automatically adjusts the operating mode. This closed-loop control ensures the treatment parameters always match the current tissue type being treated.
2Adaptability or versatility
If mode switching is performed to adapt to different tissue types, then treatment adaptability is improved, but treatment time and productivity are reduced
Solution Approach 1:
The system dynamically adapts operating parameters in real-time based on continuous tissue type detection. Instead of requiring discrete mode switching that interrupts treatment, the system continuously monitors electrical parameters and smoothly adjusts operating modes to match the current tissue type. This dynamic adaptation occurs without treatment interruption, maintaining surgical flow and productivity.
Solution Approach 2:
The system performs preliminary tissue type detection before treatment begins and continues monitoring throughout the procedure. By detecting tissue type changes in advance and proactively adjusting parameters, the system prevents treatment delays that would occur with reactive mode switching. The continuous monitoring approach allows the system to be ready with appropriate parameters before tissue type transitions occur.
3Measurement precision
If electrical parameters are monitored continuously to detect tissue type changes, then detection reliability is improved, but energy consumption and system complexity increase
Solution Approach 1:
The system monitors electrical parameters continuously but only triggers mode changes when specific parameter thresholds or patterns are detected that indicate tissue type transitions. Rather than constantly adjusting all parameters, the system selectively responds to significant changes in key parameters such as impedance or current characteristics, reducing unnecessary energy consumption while maintaining detection accuracy.
