Breast Pocket Irrigation Apparatus with Vortex Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current irrigation techniques for breast pockets during surgical procedures lack consistency and effectiveness in delivering antimicrobial fluids, often resulting in inadequate coverage and increased risk of capsular contracture due to bacterial activity and biofilm formation.
Innovation Solution
A subcutaneous irrigation apparatus with a flexible base and adjustable size channels, featuring a hub with inlet, outlet, and suction ports, and irrigation tubes that create a vortex flow pattern to ensure thorough distribution and removal of irrigation fluid, improving coverage and reducing bacterial activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hand-operated wand or elongate tools are used to introduce irrigation fluids, then the surgical procedure can be performed with simple equipment, but the irrigation coverage is inconsistent and inadequate
Solution Approach 1:
The irrigation apparatus divides the breast pocket into multiple zones by positioning several irrigation tubes at different angular orientations around the hub, with each tube responsible for irrigating a specific sector of the pocket, ensuring comprehensive and consistent coverage
Solution Approach 2:
The flexible base material allows the apparatus to adapt dynamically to the contours of the breast pocket, while the angularly positioned tubes maintain their relative orientations to ensure consistent irrigation patterns regardless of the pocket's shape or size
2Adaptability or versatility
If a fixed-size irrigation device is used, then the device structure is simple, but it cannot adapt to breast pockets of different sizes
Solution Approach 1:
The flexible base material enables the apparatus to dynamically conform to breast pockets of varying sizes and shapes, allowing a single device design to adapt to different anatomical variations without requiring multiple fixed-size devices
Solution Approach 2:
The apparatus accommodates different breast pocket sizes by changing the spatial arrangement and contact points of the flexible base with the pocket walls, allowing the same structural parameters to serve multiple size requirements
3Reliability
If irrigation fluid is introduced without vortex flow, then the delivery mechanism is simple, but the debris and bacteria removal is ineffective
Solution Approach 1:
The angular orientation of irrigation tubes relative to the hub creates curved fluid flow paths that generate vortex patterns, enhancing the mechanical action for debris and bacteria removal without requiring complex vortex-generating components
Solution Approach 2:
The apparatus utilizes hydraulic principles by introducing irrigation fluid under pressure through angularly positioned tubes, creating natural vortex flow patterns through the fluid dynamics of the angled injection points
