Multi-Suture Anchor With Adjustable Tension Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suture anchoring devices face issues such as irreversible fixation, limited ability to adjust suture tension, and complications like loosening, migration, and chondral injury due to single anchor points and knot-based securing methods, which complicate surgical procedures and increase patient risk.
Innovation Solution
A surgical line fixation device featuring a multi-suture anchor system with adjustable tension, where multiple sutures can be secured to a single anchor, and a cap mechanism that allows for secure attachment to rigid structures like bone without knots, using biocompatible materials for various surgical applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single anchor point is used to secure sutures, then the device complexity is reduced, but the reliability of fixation deteriorates due to loosening and migration
Solution Approach 1:
The anchor is divided into multiple independent sections (first section, second section, third section) that can be displaced independently along the suture line. Each section acts as an independent fixation point, distributing the mechanical load across multiple locations rather than relying on a single anchor point, thereby improving fixation stability while maintaining a relatively simple overall anchor structure.
2Ease of operation
If knot-based securing methods are used, then the ease of operation is improved, but the reliability deteriorates due to complications like loosening and chondral injury
Solution Approach 1:
The invention extracts and eliminates the knot-based securing method from the suture fixation system. Instead of relying on knots to secure sutures to the anchor, the patent uses a direct mechanical engagement system where the suture passes through the anchor sections and is secured by the cap mechanism, removing the source of knot-related complications while maintaining ease of operation.
Solution Approach 2:
The cap acts as an intermediary mechanism between the suture and the anchor. The cap secures the suture in place through a friction fit or mechanical engagement with the anchor sections, providing a reliable fixation without requiring knots. This intermediary cap mechanism simplifies the securing process while improving reliability by eliminating knot-related failures.
3Reliability
If irreversible fixation is used, then the reliability of long-term fixation is improved, but the adaptability deteriorates due to inability to adjust suture tension
Solution Approach 1:
The anchor sections are designed to be displacable along the suture line, allowing dynamic adjustment of suture tension during the surgical procedure. The sections can be moved to different positions along the suture to accommodate varying tension requirements, and the cap can be secured at different locations to maintain the adjusted tension. This dynamic capability allows the system to adapt to different surgical needs while maintaining reliable long-term fixation.
