Knotless Surgical Construct with Shuttling Loops for Multi-Suture Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods require multiple passes and separate handling of sutures for tissue repair, which can be cumbersome and time-consuming, especially in procedures like rotator cuff repair.
Innovation Solution
The development of knotless surgical constructs with shuttling loops allows for a single pass to load and pass multiple sutures simultaneously through tissue, using a suture passer without the need for additional shuttling stitches or wires, facilitating efficient tissue repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate sutures are passed through tissue using traditional methods, then each suture can be securely fixedated, but the procedural time and complexity increase significantly
Solution Approach 1:
The patent combines multiple separate suture passing operations into a single integrated construct. The surgical construct merges the first suture, second suture, and tissue itself into one unified assembly that can be passed through tissue in a single motion, eliminating the need for multiple separate passing operations and significantly reducing procedural time
Solution Approach 2:
The surgical construct serves multiple functions simultaneously: it acts as both the first suture and the second suture while also incorporating the tissue structure itself. This multi-functional design allows a single construct to perform the work of multiple separate sutures, improving efficiency without compromising fixation capability
2Reliability
If multiple separate sutures are passed through tissue using traditional methods, then each suture can be securely fixedated, but the procedural complexity increases
Solution Approach 1:
The patent combines multiple separate suture passing operations into a single integrated construct. The surgical construct merges the first suture, second suture, and tissue itself into one unified assembly that can be passed through tissue in a single motion, eliminating the need for multiple separate passing operations and significantly reducing procedural time
Solution Approach 2:
The surgical construct is segmented into distinct functional portions: a first suture portion, a second suture portion, and a tissue portion. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity in the passing mechanism, as the entire segmented construct moves as one unit through tissue
3Adaptability or versatility
If separate shuttling stitches or wires are used to pass additional sutures, then multiple sutures can be loaded, but the device complexity and procedural steps increase
Solution Approach 1:
The surgical construct serves multiple functions simultaneously: it acts as both the first suture and the second suture while also incorporating the tissue structure itself. This multi-functional design allows a single construct to perform the work of multiple separate sutures, improving efficiency without compromising fixation capability
Solution Approach 2:
The patent extracts and eliminates the need for separate shuttling stitches or wires that would traditionally be required to pass additional sutures. By integrating multiple suture functions into a single construct, the invention removes the cumbersome shuttling mechanism entirely, reducing device complexity while maintaining multi-suture loading capability
