Argon Beam Electrosurgery Blade Assembly for Cutting and Coagulation
Find Innovative SolutionsGenerate Solutions
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 both methods without mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If surgeons switch between electrosurgery and argon beam coagulation modes during surgery, then different surgical functions (cutting and coagulation) can be achieved, but surgical efficiency decreases and time is lost due to mode switching
Solution Approach 1:
The patent combines electrosurgery and argon beam coagulation capabilities into a single surgical device. The device includes both an electrosurgery blade with conductive layer and an argon beam delivery system with gas supply tube, allowing surgeons to perform both cutting and coagulation functions without switching between separate devices or modes, thereby improving surgical efficiency and eliminating time loss associated with mode switching.
2Ease of operation
If electrosurgery is used for cutting, then tissue incision can be achieved, but lateral tissue damage and necrosis increase due to heat generation
Solution Approach 1:
The patent applies local quality by using a sharp blade edge for precise cutting at the incision point while using argon beam coagulation with controlled plasma application for hemostasis. The argon beam delivers energy in a localized manner that coagulates tissue with minimal lateral thermal damage, allowing the surgeon to achieve clean cuts without the extensive heat-affected zone characteristic of traditional electrosurgery.
3Reliability
If argon beam coagulation is used to stop bleeding, then uniform and shallow coagulation surface is achieved, but smoke generation increases leading to inhalation risks
Solution Approach 1:
The patent introduces smoke evacuation as an intermediary system that actively removes smoke and debris from the surgical site. The device includes a smoke evacuation channel that draws away smoke generated during argon beam coagulation, preventing its accumulation and reducing inhalation risks for surgical personnel while maintaining the effectiveness of hemostasis.
4Device complexity
If traditional electrosurgery blade design is used, then simple structure is maintained, but versatility decreases as separate devices are needed for cutting and argon beam coagulation
Solution Approach 1:
The patent creates a universal surgical device that performs multiple functions: electrosurgery cutting, argon beam coagulation, and smoke evacuation. The device integrates an electrosurgery blade with conductive layer for cutting, a gas supply tube for delivering argon gas to the conductive layer to generate plasma for coagulation, and smoke evacuation channels for removing smoke. This multi-functional design eliminates the need for separate devices while maintaining manageable complexity through integrated architecture.
