Tissue Compression Plate Assembly for Graft Shape Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for using autograft or allograft tissue in shoulder joint repairs lack efficient means to maintain tissue compression and shape post-processing, hindering precise surgical procedures.
Innovation Solution
A plate assembly is introduced for use with a tissue compression system, comprising a first plate with a cavity to receive harvested tissue and a second plate with a projection that fits into the cavity, allowing the system to apply and maintain compression on the tissue even after the plates are removed from the press.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If harvested tissue is compressed using a press during surgical preparation, then the tissue dimension and shape are improved for surgical repair, but the tissue cannot maintain compression and shape after removal from the press
Solution Approach 1:
The plate assembly is prepared in advance with a cavity and projection structures that pre-establish the desired tissue compression geometry. When tissue is placed in the cavity and the plates are assembled, the compression shape is immediately established and maintained without requiring continuous external pressure.
Solution Approach 2:
The plate assembly acts as an intermediary device between the press and the tissue. It receives compression force from the press and translates it into sustained compression on the tissue through its structural design, allowing the tissue to maintain compressed shape even after removal from the press.
2Manufacturing precision
If harvested tissue is compressed and shaped for surgical repair, then the tissue is suitable for precise surgical procedures, but there is no efficient means to maintain tissue compression post-processing
Solution Approach 1:
The plate assembly is designed with pre-formed cavity and projection structures that establish the desired tissue compression geometry before the surgical procedure begins. This preliminary structuring allows the tissue to maintain its compressed shape during subsequent surgical operations without requiring additional compression devices.
Solution Approach 2:
The plate assembly structure itself provides the compression maintenance function through its inherent geometric design. The cavity and projection features automatically maintain tissue compression through their structural configuration, eliminating the need for external compression devices or continuous manual intervention during surgical procedures.
3Device complexity
If a simple plate structure is used for tissue compression, then the device complexity is reduced, but the ability to maintain tissue compression and shape after press removal is compromised
Solution Approach 1:
The plate assembly is divided into two separate plates - a first plate with a cavity and a second plate with a projection. This segmentation allows each plate to have a simple, straightforward structure while the combination of the two plates creates the compression maintenance function. The simplicity of individual components is preserved while achieving the desired tissue compression stability.
