Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrosurgical devices for minimally invasive tissue dissection lack the ability to efficiently deliver electrosurgical energy through a cannula while allowing for precise orientation and movement of the lysing tip, limiting their effectiveness in surgical procedures.
Innovation Solution
An electrosurgical device with a lysing tip configured for deployment through a cannula, featuring an energy delivery side and an orientational-deployment side, along with a deployment assembly that allows for selective repositioning between delivery and treatment configurations, enabling the tip to extend perpendicular to the cannula axis for enhanced tissue dissection and modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lysing tip is delivered through the cannula in a parallel configuration, then the delivery is simplified and the tip can be easily inserted, but the tissue dissection capability is limited during treatment
Solution Approach 1:
The lysing tip is designed with rotational capability that allows it to dynamically change orientation from parallel to perpendicular relative to the cannula axis. The deployment assembly enables this dynamic repositioning, transforming the static delivery configuration into an active treatment configuration that maximizes tissue dissection effectiveness while maintaining ease of initial delivery
Solution Approach 2:
The invention introduces a rotational dimension to the lysing tip deployment. By enabling the tip to rotate from a parallel orientation (during delivery) to a perpendicular orientation (during treatment), the system adds a dimensional transformation that resolves the contradiction between simple delivery and effective tissue dissection
2Reliability
If the lysing tip is positioned perpendicular to the cannula axis for effective tissue dissection, then the treatment effectiveness is improved, but the delivery through the cannula becomes more difficult
Solution Approach 1:
The lysing tip is delivered to the treatment site in a parallel configuration that facilitates easy cannula passage. Once positioned, the deployment assembly rotates the tip to the perpendicular treatment configuration. This preliminary action of delivering in a simplified orientation followed by activation of the treatment orientation eliminates the delivery difficulty while maintaining treatment effectiveness
Solution Approach 2:
The system transitions from a static delivery state to a dynamic treatment state through rotational repositioning. The deployment assembly provides the mechanical means to transform the tip orientation after delivery, ensuring that the full perpendicular effectiveness is achieved without compromising the initial delivery ease
3Measurement precision
If the lysing tip is repositioned between delivery and treatment configurations, then the surgical precision is improved, but the device complexity increases
Solution Approach 1:
The deployment assembly incorporates rotational joints and actuation mechanisms that enable controlled repositioning of the lysing tip. This dynamic capability allows precise orientation adjustment from parallel to perpendicular configurations, achieving surgical precision while the modular design of the deployment assembly manages the inherent complexity through standardized mechanical components
