Integrated Electrosurgery Blade for Simultaneous 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, necessitating a device that can perform both cutting and bleeding cessation simultaneously.
Innovation Solution
An electrosurgery blade assembly with an integrated non-conductive housing for argon gas delivery, enabling simultaneous cutting and coagulation capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If surgeons use separate electrosurgery tools for cutting and argon beam coagulation, then each tool can be optimized for its specific function, but the surgeon must switch between modes during surgery increasing operation time
Solution Approach 1:
The patent combines electrosurgery blade functionality with argon beam coagulation capability into a single integrated device. The electrosurgery blade assembly includes an electrode blade for cutting and a non-conductive housing with an opening for argon gas delivery, allowing both cutting and coagulation functions to be performed simultaneously without switching between separate tools or modes.
Solution Approach 2:
The electrosurgery blade is designed to perform multiple functions: it can function as a traditional electrosurgery blade for cutting tissue, as an argon beam coagulation device for stopping bleeding, or in combination modes. This multi-functionality eliminates the need for separate specialized tools and reduces mode switching during surgical procedures.
2Reliability
If argon beam coagulation is used to stop bleeding, then blood loss is controlled, but visibility at the surgical site is obscured by smoke
Solution Approach 1:
The patent integrates smoke evacuation capability directly into the electrosurgery blade assembly. The non-conductive housing includes an opening that serves dual purposes: delivering argon gas for coagulation and evacuating smoke generated during tissue processing. This simultaneous delivery and evacuation of gases maintains surgical site visibility while achieving effective hemostasis.
3Productivity
If electrosurgery blade is used for cutting, then tissue incisions are made, but bleeding at the surgical site continues
Solution Approach 1:
The electrosurgery blade assembly combines cutting functionality with integrated argon beam coagulation capability. The electrode blade can cut tissue while the non-conductive housing delivers argon gas to coagulate blood vessels simultaneously, achieving both cutting speed and hemostasis control in a single continuous action without requiring separate steps or tool changes.
