Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cutting methods are used in endoscopic procedures, then the surgical procedure can be performed, but blood loss increases and visibility deteriorates
Solution Approach 1:
The patent replaces traditional mechanical cutting blades with electromagnetic radiation (RF and microwave energy) to cut and coagulate tissue. This substitution eliminates mechanical blade contact that causes bleeding, while the electromagnetic energy simultaneously coagulates blood vessels, achieving both cutting and hemostasis without blood loss that would obscure visibility.
Solution Approach 2:
The system dynamically adjusts electromagnetic radiation parameters (frequency, power level, duration) based on real-time tissue characteristics and procedural requirements. By optimizing these parameters, the system achieves precise tissue treatment with minimal blood loss, maintaining visibility throughout the endoscopic procedure.
2Reliability
If electromagnetic radiation is used for tissue treatment, then blood loss is reduced, but control precision and adaptability to different tissue types are challenged
Solution Approach 1:
The system incorporates real-time feedback mechanisms that monitor tissue response to electromagnetic radiation and adjust energy delivery accordingly. Sensors detect tissue characteristics, power absorption rates, and procedural parameters, allowing the control system to dynamically optimize energy delivery for precise treatment of different tissue types while maintaining blood loss reduction.
Solution Approach 2:
The system employs dynamic adjustment of electromagnetic radiation parameters during the procedure based on real-time conditions. The control system can modify frequency, power levels, and exposure duration in response to changing tissue properties, ensuring precise and adaptable treatment while maintaining hemostasis.
3Device complexity
If a single integrated electrosurgical system is used, then system complexity is reduced, but versatility and adaptability to different procedural requirements are limited
Solution Approach 1:
The patent integrates multiple electromagnetic radiation sources (RF and microwave generators) into a single unified electrosurgical system that can perform various procedures including cutting, coagulation, and ablation. This multi-functional system maintains low complexity through centralized control while providing versatility to handle different tissue types and procedural requirements through programmable energy delivery modes.

Implementation Method 1
A signal generator module in communication with the controller module so as to receive the control commands, the signal generator module operable to generate and control electromagnetic (EM) radiation based on the control commands
Implementation Method 2
as an electric current passes through a tissue matrix (aided by the ionic contents of the cells and the intercellular electrolytes), the impedance to the flow of electrons across the tissue generates heat
Implementation Method 3
enough heat is generated within the cells to vaporise the water content of the tissue
Implementation Method 4
The applied voltage is then appears almost entirely across this void which ionises as a result, forming a plasma, which has a very high volume resistivity compared to tissue
Implementation Method 5
The microwave channel contains components for generating and controlling a microwave frequency electromagnetic signal at a power level suitable for treating (e.g. coagulating or ablating) biological tissue
