Compression System for Embedding Graft into Surgical Implant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for re-establishing stability in a shoulder joint after injury, such as using autograft, allograft, or synthetic grafts, lack an efficient method to embed and secure the graft within the joint for effective healing.
Innovation Solution
A compression system comprising a first press component with cavities to receive a graft and a surgical implant, and a second press component with a projection to embed at least a portion of the graft into the surgical implant by applying force, facilitating the creation of a construct for surgical repair or reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional graft placement methods are used, then the surgical procedure can be completed, but the graft cannot be efficiently embedded or secured within the joint for effective healing
Solution Approach 1:
The press component is divided into multiple segments including a first press component with a cavity, a second press component with a projection, and optional third and fourth press components with additional projections. This segmentation allows each component to perform a specific function in the embedding process, enabling efficient and secure graft embedding while maintaining ease of manufacture through modular design.
2Productivity
If a compression system with multiple press components is used, then graft embedding efficiency is improved, but the device complexity increases
Solution Approach 1:
Multiple press components (first, second, third, and fourth press components) are combined into a single integrated compression system that operates together to embed the graft. The components are designed to work in coordination, with projections that fit into corresponding cavities, creating a unified system that achieves efficient graft embedding without requiring multiple separate devices.
Solution Approach 2:
The press components are designed with universal features that allow them to perform multiple functions. The cavity and projection design can accommodate different graft types and sizes, and the same basic component structure can be used for different embedding locations and surgical applications, reducing overall system complexity while maintaining high productivity.
3Stability of the object's composition
If the graft is not securely embedded into the surgical implant, then the construct lacks stability for healing, but embedding requires a specialized compression system
Solution Approach 1:
The graft is embedded within the surgical implant construct through a nested arrangement where the graft material is positioned inside or within the structure of the surgical implant. The press components with cavities and projections facilitate this nesting by compressing and securing the graft within the implant, creating a stable integrated construct without requiring overly complex external fixation devices.

Function Achieved in This Case
The system enables the efficient embedding of grafts into surgical implants, promoting healing and stability in joint repairs, such as soft tissue repairs, by creating a secure and integrated construct.
Implementation Method 1
embedding at least a portion of the graft into the surgical implant by applying a force to the graft by moving a second press component relative to the first press component
