An ultrapolar electrosurgery blade with active and return electrodes positioned on opposing sides of a non-conductive planar member, allowing for cutting and coagulation with reduced tissue damage, and optionally integrated with a smoke evacuation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If monopolar electrosurgery is used, then cutting and coagulation effectiveness is improved, but excessive heat generation causes tissue damage and necrosis
Solution Approach 1:
The electrosurgery blade is segmented into multiple independent electrode elements arranged in a grid pattern on both sides of the blade. Each electrode can be independently controlled to deliver energy, allowing selective activation of specific electrode pairs to treat different tissue areas simultaneously while distributing heat generation across multiple sites rather than concentrating it at a single point.
Solution Approach 2:
The blade provides different electrode configurations and activation patterns for different treatment needs. Specific electrode pairs can be selectively activated based on the local tissue condition and surgical requirements, enabling precise control over where energy is delivered and how much heat is generated in each local area.
2Object-affected harmful factors
If bipolar electrosurgery is used, then tissue damage is reduced, but ability to cut and coagulate large bleeding areas is limited
Solution Approach 1:
The blade contains multiple electrode pairs arranged in a grid pattern, creating numerous small bipolar treatment zones across the blade surface. By activating multiple electrode pairs simultaneously or sequentially, the system can treat large areas of bleeding tissue while maintaining the safety benefits of bipolar electrosurgery, as each electrode pair creates a localized current path confined to the tissue between electrodes.
Solution Approach 2:
The blade is designed to perform multiple functions: it can treat small focal points by activating single electrode pairs, treat large diffuse bleeding areas by activating multiple electrode pairs simultaneously, and adapt to different tissue depths and types. The same blade structure serves both bipolar safety requirements and multi-area treatment capabilities.
3Adaptability or versatility
If monopolar electrosurgery is used, then versatility and effectiveness are improved, but high voltage and high RF energy pass through the patient
Solution Approach 1:
The monopolar blade is segmented into multiple independent electrode elements that can be selectively activated. This allows the system to treat large areas by distributing energy across multiple electrode pairs rather than concentrating high voltage through a single return path, reducing the risk of energy passing through the patient while maintaining monopolar versatility.
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
Enables precise cutting and coagulation of large tissue areas with reduced heat and tissue necrosis, while optionally evacuating smoke and debris during surgical procedures.
Implementation Method 1
Electrosurgery uses an RF electrosurgical generator (also known as an electrosurgical unit or ESU) and a handpiece with an electrode to provide high frequency, alternating radio frequency (RF) current input at various voltages to cut or coagulate biological tissue
