Septal Perforation Measuring Device for Accurate Prosthesis Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring nasal septal perforations, such as using small rulers or visual estimation, are inaccurate, making it difficult to select appropriately sized septal buttons for patient comfort and satisfaction.
Innovation Solution
A septal perforation measuring device with an elongated handle and a head portion, featuring a base and a protrusion of varying sizes and shapes, designed to be inserted into the nostril and septal perforation to determine the precise size and shape for fitting a septal button prosthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measurement methods (small ruler or visual estimation) are used, then the measurement process is simple, but the measurement precision is poor
Solution Approach 1:
The measuring device is segmented into distinct functional components: an elongated handle for manipulation and a head portion with multiple protrusions of different sizes and shapes. Each protrusion can be selectively engaged with the perforation to determine the appropriate septal button size, breaking down the measurement task into discrete, manageable steps that improve precision without requiring a complex overall device structure.
Solution Approach 2:
The head portion features multiple protrusions with locally differentiated sizes and shapes, each designed to match specific perforation dimensions. This local variation in geometry allows precise matching to different perforation types while keeping the overall device structure relatively simple and manageable.
2Adaptability or versatility
If a single-size measuring device is used, then the device structure is simple, but the adaptability to different perforation sizes is poor
Solution Approach 1:
The measuring device incorporates multiple protrusions of varying sizes and shapes on a single head portion, enabling one device to measure multiple different perforation types. This multi-functional design allows the same device to accommodate various septal button sizes (e.g., 5mm, 7mm, 10mm) without requiring separate measuring tools for each size, thereby improving adaptability while maintaining reasonable device simplicity.

AI summary
A septal perforation measuring device includes an elongated handle and a head portion attached to an end of the elongated handle. The head portion is configured and sized to be inserted into a patient's nostril and includes a base portion and a protrusion extending from a face of the base portion. The protrusion is configured and sized to be inserted into a septal perforation of the patient for assisting in determining a size of the septal perforation.
