Guided Bipolar RF Treatment for Nasal Wall Insufficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for nasal wall insufficiency, such as grafting and implants, are complex and invasive, while electrosurgical methods are cumbersome and require surgery.
Innovation Solution
A method involving a puncture guide with a stabilizing frame and bipolar radiofrequency probe is used to create targeted lesions in nasal wall tissue, stiffening it through electrosurgical heating, stabilized by the frame, and allowing the tissue to conform to the guide's shape during cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional treatments (grafting, implants, suture suspension) are used for nasal wall insufficiency, then the nasal wall strength is improved, but the treatment complexity and invasiveness increase
Solution Approach 1:
The patent replaces traditional mechanical treatments (grafting, implants, suture suspension) with electrosurgical therapy. A bipolar radiofrequency probe is inserted through the puncture guide to deliver electrical energy that creates thermal lesions in the nasal wall tissue, causing collagen denaturation and stiffening without requiring mechanical implants or grafts
Solution Approach 2:
The patent changes the physical state of the nasal wall tissue through controlled heating. The bipolar radiofrequency probe raises the temperature of the tissue to create thermal lesions, which alters the collagen structure and increases tissue stiffness. This parameter change (temperature) achieves the desired strengthening effect without mechanical intervention
2Ease of operation
If electrosurgical therapy is used for nasal wall insufficiency, then the treatment simplicity is improved, but the procedure complexity and surgical requirement increase
Solution Approach 1:
The puncture guide serves as an intermediary device that simplifies the electrosurgical procedure. It provides a stable platform with multiple puncture passages that guide the bipolar radiofrequency probe through the nasal wall, enabling precise and repeated lesion creation without complex surgical maneuvers
Solution Approach 2:
The puncture guide is inserted and positioned in advance to establish the treatment pathway. The guide frame is placed in the nasal passage before the electrosurgical lesions are created, providing structural support and guiding the probe through the tissue during the procedure
3Strength
If multiple lesions are created in nasal wall tissue through repeated piercing, then the stiffening effect is improved, but the treatment time increases
Solution Approach 1:
The puncture guide divides the treatment area into multiple discrete puncture passages, allowing systematic creation of multiple lesions through a structured approach. This segmentation enables efficient coverage of the nasal wall while maintaining control over the treatment process
Solution Approach 2:
The bipolar radiofrequency probe creates multiple lesions through continuous repeated piercing through the puncture guide passages. The guide remains in place throughout the procedure, allowing uninterrupted delivery of electrosurgical energy to multiple locations without removing or repositioning the guide between lesions
