Ablation Probe Guidance Indicator for Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ablation probes are difficult to position accurately relative to target tissue while minimizing damage to surrounding healthy tissue, as they lack suitable surfaces and features for aligning with guidance system references.
Innovation Solution
Incorporating a guidance indicator on the ablation probe, which can include markings, optical sensors, and a removable attachment mechanism, to facilitate alignment with laser guidance systems and ensure precise positioning of the probe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing ablation probes are used without guidance indicators, then the probe structure remains simple, but the probe cannot be accurately positioned relative to target tissue
Solution Approach 1:
The patent introduces a guidance indicator as an intermediary component that mediates between the ablation probe and the guidance system. The indicator includes markings (such as crosshairs or target symbols) that align with laser references from the guidance system, enabling precise positioning without modifying the core ablation probe structure. This intermediary element bridges the gap between the simple probe design and the need for accurate positioning.
2Ease of operation
If guidance indicators are integrated into the ablation probe, then alignment with guidance system is improved, but the probe design becomes more complex
Solution Approach 1:
The guidance indicator is designed as a separate, modular component that can be attached to or integrated with the ablation probe. This segmentation allows the indicator to be independently designed and optimized for alignment functionality, while the probe itself maintains its simple ablation-focused structure. The modular approach enables easy attachment and removal of the guidance indicator without permanently complicating the probe design.
3Measurement precision
If the guidance indicator is permanently attached to the probe, then alignment accuracy is maintained, but the indicator cannot be removed or adjusted
Solution Approach 1:
The guidance indicator is designed with dynamic attachment characteristics, allowing it to be securely fixed during the ablation procedure to maintain alignment accuracy, yet easily removable or adjustable between procedures. The indicator may include attachment mechanisms such as clips, adhesives, or magnetic elements that provide stable fixation during use but allow for straightforward removal when needed, enabling adaptability across different surgical contexts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The guidance indicator enhances the ability of medical professionals to accurately position the ablation probe, reducing the risk of damage to surrounding tissues and improving treatment efficacy by aligning the probe with desired orientations and locations.
Implementation Method 1
The guidance indicator may include at least one optical sensor and is configured to determine a predetermined alignment of the probe
Data Source
AI summary
A guidance indicator includes an indicator platform having an indicator surface and a mounting portion connected to the indicator platform and supporting the indicator surface in a predetermined orientation relative to a needle of an ablation probe. The mounting portion is adapted to removably attach to a complimentary attachment post of the ablation probe.
