Interlocking Tissue Matrix for Secure Bone Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tissue treatment methods face challenges in securely positioning and adjusting sutures around tissue or bone, particularly when the tissue or bone shape does not allow for a slip-over configuration, leading to increased time and complexity in securing tissue or bone relative to other structures in the body.
Innovation Solution
A composition comprising interlocking components, such as holes or slits and tabs with flared sections, that can be wrapped around tissue or bone without the need for sutures, allowing for secure attachment and adjustment by interlocking mechanisms that prevent retraction, utilizing a tissue matrix for flexibility and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sutures are used to secure tissue or bone, then the tissue can be retained relative to other structures, but the procedural time increases and the complexity of the procedure increases
Solution Approach 1:
The invention extracts the time-consuming suture tying step from the tissue securing process by using a pre-formed mesh structure with integrated anchoring features. The mesh is simply positioned and secured with minimal suturing or alternative fixation methods, eliminating the need for complex suture manipulation and knot tying while maintaining reliable tissue retention.
Solution Approach 2:
The mesh structure serves as an intermediary between the tissue and the securing mechanism. Instead of directly suturing tissue to tissue or tissue to bone, the mesh acts as a mediator that distributes forces and provides a stable framework for tissue retention, simplifying the fixation process.
2Reliability
If sutures are used to secure tissue or bone, then the tissue can be retained relative to other structures, but the device complexity increases
Solution Approach 1:
The mesh is divided into multiple cells or openings with integrated anchoring features at specific locations. This segmentation allows the mesh to be customized for different anatomical sites and provides multiple discrete anchoring points that simplify the securing process compared to using continuous sutures around the entire tissue structure.
Solution Approach 2:
The mesh structure is designed to be self-retaining through its geometric configuration and material properties. The mesh maintains its shape and provides inherent stability without requiring complex external fixation devices, reducing procedural complexity while ensuring reliable tissue retention.
3Ease of operation
If a slip over type product is used, then the positioning is simplified, but the product cannot be used when the tissue or bone shape does not permit
Solution Approach 1:
The mesh structure incorporates regions with different properties - some areas are designed for easy positioning and wrapping around the tissue, while other specific locations include reinforced anchoring features such as tabs, protrusions, or integrated sutures. This local differentiation allows the mesh to adapt to various anatomical shapes while maintaining ease of operation in the positioning regions.
Solution Approach 2:
The mesh is designed with flexible segments that can dynamically adapt to different anatomical configurations. The mesh can be stretched, folded, or shaped during positioning to accommodate various tissue or bone geometries, then locked into place using the integrated anchoring features, providing both ease of operation and anatomical versatility.
