Suction Swab Drying Osteochondral Defects for Microfracture Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Osteochondral defects in joints, such as knees, ankles, or shoulders, often fail to heal on their own and can lead to significant arthritic pain, necessitating surgical intervention like microfracture surgery, where drying the defect site is crucial for effective repair material application but existing methods are inadequate.
Innovation Solution
A suction swab is used to dry osteochondral defects by suctioning moisture or communicating an inert gas to the site, facilitating the preparation of the defect for repair materials during microfracture surgeries or other osteochondral defect repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional suction devices are used to remove moisture from the osteochondral defect, then moisture removal capability is limited, but the surgical procedure time is extended
Solution Approach 1:
The patent combines suction and drying functions into a single integrated device. The suction swab device merges the suction mechanism with a swab tip that can directly contact and absorb moisture from the osteochondral defect surface, allowing simultaneous suction of bulk fluid and absorption of residual moisture in one operation, thereby improving moisture removal efficiency without extending surgical time
Solution Approach 2:
The suction swab device performs multiple functions: it suctiones excess moisture, dries the defect surface, and can deliver repair materials. This multi-functional design eliminates the need for separate suction devices, swabs, and material delivery tools, streamlining the surgical workflow and reducing overall procedure time while maintaining effective moisture removal
2Manufacturing precision
If the osteochondral defect is not adequately dried, then repair material application is compromised, but using excessive drying methods may damage surrounding tissue
Solution Approach 1:
The suction swab device concentrates the drying action precisely at the osteochondral defect site through its tip design. The swab tip contacts only the defect area to remove moisture, while the suction mechanism selectively removes fluid from the localized region. This localized approach ensures adequate drying of the repair area without exposing surrounding healthy tissue to excessive drying effects or mechanical damage
Solution Approach 2:
The suction swab acts as an intermediary tool between the surgeon and the osteochondral defect. It provides controlled, gentle moisture removal through the swab tip while the suction mechanism prevents pooling of excess fluid. This intermediary approach achieves the necessary dryness for repair material application without the harsh effects of direct high-speed airflow or excessive mechanical manipulation that could damage surrounding tissue
