Multi-Point RF Probe for Precise Tissue Ablation via Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio frequency (RF) based tissue treatments, such as RF ablation, face challenges in precisely targeting specific tissues without damaging surrounding healthy tissues due to the lack of precise control over the interaction of RF signals within the body.
Innovation Solution
A multi-point probe system with at least two transmission points is used to deliver RF signals in a calculated pattern, forming interactions such as constructive and destructive interference to create hot spots at the treatment location, allowing for precise ablation while minimizing impact on non-target tissues, and includes receiving points to measure energy and adjust the treatment based on dielectric properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If RF signals are delivered to treat target tissue, then ablation effect is achieved, but surrounding healthy tissues may be damaged
Solution Approach 1:
The probe is divided into multiple transmission points (at least two) that can independently deliver RF signals. This segmentation allows the treatment to be divided into multiple focused beams that converge at the target, reducing energy dispersion and protecting surrounding tissues from excessive energy exposure.
Solution Approach 2:
The system creates localized hot spots at specific treatment locations through constructive interference of RF signals from multiple transmission points. The energy distribution is non-uniform, with high energy concentration precisely at the target tissue and lower energy in surrounding areas, achieving localized treatment effect.
2Manufacturing precision
If multiple RF transmission points are used to improve precision, then signal interaction control complexity increases
Solution Approach 1:
The system includes receiving points that intercept energy delivered from transmission points and provide feedback signals. This feedback mechanism allows the system to measure actual energy delivery and tissue response, enabling real-time adjustment of transmission patterns to optimize treatment precision while managing signal interaction complexity.
Solution Approach 2:
The system controls signal interactions by adjusting parameters such as phase, frequency, and input power of RF signals from different transmission points. By dynamically changing these parameters, the system can create desired interference patterns (constructive at target, destructive in surrounding areas) without requiring overly complex hardware configurations.
