Needle Bending Mechanism for Precise Fine-Gauge Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fine-gauge needles used in medical procedures are prone to deflection due to unbalanced force interactions, leading to placement failures and imprecise manual bending methods that lack customization for specific procedures or patient characteristics.
Innovation Solution
A needle bending device comprising a base, hollow slider conduit, and bending element, allowing for customizable bends of up to 30 degrees, with a clamp and fulcrum mechanism to secure and bend the needle precisely, enabling reproducible and precise needle placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual needle bending is performed by medical professionals, then customization for specific procedures is possible, but precision and reproducibility are compromised
Solution Approach 1:
A specialized bending device serves as an intermediary tool between the medical professional and the needle. The device includes a holder that secures the needle, a bending element with fulcrum mechanism, and angle indicators that guide the bending process. This intermediary tool enables precise, reproducible bends while maintaining customization capability for different procedural needs.
2Manufacturing precision
If pre-bent needles with mass-produced bend angles are used, then manufacturing precision is improved, but adaptability to specific procedures and patient characteristics is limited
Solution Approach 1:
The bending device transforms a static, fixed-bend needle into a dynamic system where the bend angle can be adjusted and customized. The device allows medical professionals to create precise bends ranging from 5 to 30 degrees based on specific procedural requirements and patient characteristics, rather than being limited to pre-determined fixed angles.
3Object-affected harmful factors
If fine-gauge needles are used to reduce puncture headaches, then patient comfort is improved, but needle deflection and placement failure risk increase
Solution Approach 1:
The device applies preliminary counter-action by pre-bending the fine-gauge needle in the opposite direction of expected tissue deflection forces. This anticipatory bending compensates for the needle's tendency to deflect during insertion, ensuring more reliable and accurate needle placement while maintaining the benefits of using fine-gauge needles for patient comfort.
