Electrosurgery Probe With Hollow Mid-Segment For Smoke Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrosurgery systems face limitations in removing smoke, liquids, and debris during surgical procedures due to the need for additional tubes that obstruct the surgical site and require disposable handpieces with smoke evacuation channels, limiting the versatility and efficiency of these systems.
Innovation Solution
An electrosurgery system with a handpiece having a main flow passage and an exhaust segment, along with a probe comprising a conductive element with a hollow mid-segment for suction and irrigation, allowing for interchangeable tips and simultaneous suction/coagulation without the need for additional tubes, enabling efficient smoke and debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If additional tubes are used to remove smoke and debris from the surgical site, then smoke evacuation is improved, but the surgical site becomes obstructed and visualization is impeded
Solution Approach 1:
The patent combines the electrosurgery probe and smoke evacuation tube into a single integrated device. The hollow probe structure allows electrical current to pass through its center while the surrounding tube evacuates smoke, eliminating the need for separate tubes that would obstruct the surgical site and impair visualization.
Solution Approach 2:
The integrated probe serves multiple functions simultaneously: it delivers electrosurgical current for cutting or coagulation through its conductive element, while the hollow structure surrounding it provides smoke evacuation. This multi-functionality eliminates the need for additional separate tubes or devices.
2Object-affected harmful factors
If a disposable handpiece with smoke evacuation channel is used, then smoke removal is achieved, but device complexity and cost increase
Solution Approach 1:
The invention separates the smoke evacuation function from the handpiece and integrates it directly into the reusable probe. The hollow probe structure contains the evacuation channel, while the handpiece remains simple and reusable. This segmentation allows the complex evacuation feature to be in the disposable probe rather than requiring a complex disposable handpiece.
Solution Approach 2:
The hollow probe acts as an intermediary that carries both the electrosurgical current and the smoke evacuation function. By placing the evacuation channel in the probe rather than the handpiece, the system avoids the need for a complex disposable handpiece with integrated evacuation channels.
3Adaptability or versatility
If multiple separate devices are used for electrosurgery and smoke evacuation, then functional versatility is achieved, but device complexity and procedural time increase
Solution Approach 1:
The patent merges the electrosurgery probe and smoke evacuation tube into a single integrated device, reducing the number of separate devices from two to one. This integration maintains full functional versatility while simplifying the overall system and reducing procedural complexity.
Solution Approach 2:
The integrated probe provides multiple functions in a single device: electrosurgical cutting, coagulation, and smoke evacuation. This multi-functionality eliminates the need for multiple separate devices and reduces the complexity of having to manage and coordinate multiple separate instruments during surgery.
