Solution Overview

Problem

Current electrosurgical tools require surgeons to switch between electrosurgery and argon beam coagulation modes during surgery, leading to inefficiencies, tissue damage, and smoke inhalation risks.

Innovation Solution

An electrosurgery blade with a non-conductive planar member and conductive layer, combined with a non-conductive tube member for inert gas supply, enabling simultaneous cutting and coagulation using a single device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If surgeons use separate electrosurgery and argon beam coagulation devices, then each function can be performed effectively, but surgical efficiency decreases and time is lost switching between modes

Engineering Contradiction:
Improvesurgical efficiencyVSAvoidtime switching between modes
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines electrosurgery cutting capability and argon beam coagulation capability into a single integrated surgical device. The electrosurgery blade assembly includes a conductive layer that can function as an electrode for RF cutting, while the same or adjacent structure supports argon gas delivery for plasma-based coagulation. This merging eliminates the need to switch between separate devices, improving surgical efficiency and reducing time loss.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The surgical device is designed with multi-functionality, allowing it to perform both electrosurgery cutting and argon beam coagulation using a single instrument. The blade assembly can operate in cutting mode when RF energy is applied, and in coagulation mode when argon gas is ionized and applied to tissue. This universal design enables surgeons to have both capabilities available simultaneously without needing multiple specialized tools.

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

2Ease of operation

If continuous RF high voltage conduction is used for cutting, then cutting function is achieved, but lateral tissue damage and necrosis increase

Engineering Contradiction:
Improvecutting functionVSAvoidlateral tissue damage and necrosis
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The electrosurgery blade features a sharp edge geometry that concentrates RF energy at the cutting tip rather than distributing it across a broader area. This local concentration of energy enables precise cutting with minimal lateral thermal damage to surrounding tissues. The conductive layer is configured to deliver RF energy focally at the cutting edge, improving cut quality while reducing necrosis.

Inventive Principle:
Principle #3Local quality

3Reliability

If electrosurgery and argon beam coagulation are performed separately, then each procedure can be optimized, but smoke inhalation risk increases due to prolonged surgical time

Engineering Contradiction:
Improveprocedure optimizationVSAvoidsmoke inhalation risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The integrated device allows surgeons to perform cutting and coagulation in continuous sequence without interruption or device switching. The electrosurgery blade can cut tissue while the same or adjacent structure immediately provides coagulation control, maintaining continuous useful action throughout the procedure. This continuity reduces overall surgical time and consequently reduces smoke inhalation exposure compared to switching between separate devices.

Inventive Principle:
Principle #20Continuity of useful action
