Modular Strap Tie for Uniform Wound Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound closure methods often result in uneven forces across the wound, leading to ineffective healing and scar formation, particularly in scenarios where clinical facilities are not readily accessible.
Innovation Solution
A strap tie assembly comprising two strap ties with engagement members and movement restriction members that allow for even force distribution across a wound by engaging and preventing translation of the straps, ensuring consistent tension and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wound closure methods (sutures, staples, clips) are used, then wound edges can be approximated, but uneven forces are applied across the wound leading to ineffective healing and scar formation
Solution Approach 1:
The strap tie system divides the wound closure function into multiple discrete components: individual strap ties with engagement members, movement restriction members positioned at specific intervals, and modular bodies that can be independently adjusted. This segmentation allows each component to contribute to uniform force distribution while maintaining overall system reliability for effective healing.
2Adaptability or versatility
If clinical facilities are not readily accessible, then treatment flexibility is improved, but proper wound closure becomes difficult to achieve
Solution Approach 1:
The strap tie system incorporates self-adjusting features including movement restriction members that automatically limit strap displacement, engagement members that self-lock into place, and a modular design that allows non-clinical users to achieve precise wound closure without specialized training or equipment. This enables proper wound closure in remote locations while maintaining treatment precision.
3Ease of operation
If engagement members are used to prevent strap translation, then force distribution uniformity is improved, but device complexity increases
Solution Approach 1:
The engagement member and movement restriction member functions are merged into an integrated system where the engagement member engages with the movement restriction member to simultaneously achieve strap positioning and force distribution. This consolidation reduces overall device complexity compared to having separate mechanisms for each function, while maintaining uniform force distribution across the wound.

AI summary
A strap tie includes a body including a receiving channel and a strap engagement member. The receiving channel extends through the body. The receiving channel is configured to receive a remote strap. The engagement member is configured to engage a movement restriction member of the remote strap to prevent translation of the remote strap away from the body. The strap extends from the body. The strap includes a proximal end attached to the body, a distal end opposite the proximal end, and a plurality of movement restriction members. The rotational element of the body is configured to removably couple to a base to allow the strap tie to rotate relative to the base.
