Solution Overview

Problem

Current electro-surgical systems lack the ability to seamlessly switch between monopolar and bipolar modes without requiring tool removal or additional components, limiting their versatility and efficiency in surgical procedures.

Innovation Solution

A modular electrosurgical system with a surgical mechanical arm that includes a motor unit and a tool configured to operate in both monopolar and bipolar modes, allowing for easy switching between operational modes without detaching the arm from the motor unit, using a system of actuators and electrical pathways to manage power distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single electrosurgical tool is designed to support both monopolar and bipolar modes, then versatility and efficiency are improved, but device complexity increases

Engineering Contradiction:
Improveoperational mode versatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electrosurgical tool is designed with a universal structure that supports both monopolar and bipolar operational modes. The tool includes a handle with a monopolar electrode and a shaft with bipolar electrodes, allowing the same physical device to perform both types of electrosurgery by switching electrical connections rather than requiring separate tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically reconfigures its electrical pathways based on the selected operational mode. A switching mechanism within the handpiece dynamically connects or disconnects electrical pathways between the generator and different electrode configurations, allowing the tool to adapt its functionality in real-time without physical changes to the tool structure.

Inventive Principle:
Principle #15Dynamics

2Productivity

If separate tools are used for monopolar and bipolar procedures, then operational simplicity is maintained, but productivity and efficiency deteriorate due to tool changes

Engineering Contradiction:
Improvesurgical efficiencyVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The electrosurgical tool is designed with a universal structure that supports both monopolar and bipolar operational modes. The tool includes a handle with a monopolar electrode and a shaft with bipolar electrodes, allowing the same physical device to perform both types of electrosurgery by switching electrical connections rather than requiring separate tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables continuous surgical action by allowing seamless switching between monopolar and bipolar modes without requiring tool removal or replacement. The generator and handpiece remain connected throughout, and the switching mechanism enables mode transitions without interrupting the surgical workflow or requiring repositioning of the tool.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If a switching mechanism is integrated into the handpiece, then mode switching becomes seamless, but device complexity increases

Engineering Contradiction:
Improvemode switching convenienceVSAvoidhandpiece complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The switching mechanism is merged with the handpiece structure, integrating the electrical switching components directly into the existing handpiece assembly. This combination allows mode switching to occur within the handpiece itself rather than requiring external switching devices or complex external wiring configurations.

Inventive Principle:
Principle #5Merging (Combining)
