Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bone grafts formed from calcium phosphate compounds, primarily in powder form, face issues such as spillage during grafting, insufficient porosity, and slow bone formation due to inadequate blood absorption and space for bone growth, leading to ineffective bone formation.
Innovation Solution
A 3-dimensional block type bone graft with intersecting channels in X-Y-Z directions, providing a porous structure for blood circulation and bone growth, preventing spillage and allowing for easy application and effective bone formation through osteoinduction and osteoconduction, and can be broken down into smaller pieces for volume maintenance and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional powder bone graft is used, then the bone graft material is easy to provide in sufficient amount, but the bone graft may be spilled from bone defect during grafting causing large loss and making grafting difficult and time-consuming
Solution Approach 1:
The patent employs a porous three-dimensional block structure with interconnected channels that allows the bone graft material to be provided in sufficient quantities while preventing spillage. The porous architecture enables the material to maintain its shape and stay contained within the bone defect site, eliminating the spillage issues associated with conventional powder forms.
2Quantity of substance
If conventional powder bone graft is used, then the material can be easily provided, but the bone graft has insufficient porosity resulting in slow blood absorption and insufficient space for bone growth
Solution Approach 1:
The invention utilizes a three-dimensional block structure with interconnected porous channels that provide adequate porosity for effective blood absorption and bone growth. The porous architecture creates sufficient space within the bone graft for osteoinduction and osteoconduction, ensuring reliable bone formation while maintaining the ability to provide sufficient material quantity.
3Quantity of substance
If conventional powder bone graft is used, then the material is available in sufficient quantity, but the grafting requires long time and is difficult to perform
Solution Approach 1:
The three-dimensional block type porous structure enables the bone graft to be provided in sufficient quantities while significantly reducing the grafting time. The pre-formed block structure eliminates the need for time-consuming manipulation and placement procedures required for powder materials, making the grafting process faster and easier to perform.
