Hemostatic Mesh Device for Sternal Bleeding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bone hemostatic materials are difficult to apply effectively to elongated and narrow bleeding surfaces, such as the medially-divided sternum, during surgical procedures, and may damage surgical gloves due to their consistency and adhesion properties.
Innovation Solution
A surgical device comprising a surgical material, typically in the form of a ribbon or sheet, sandwiched between two layers of a support material that can be cut or folded for precise application to bleeding surfaces, providing mechanical hemostasis without chemical agents and protecting gloves from sharp bone edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hemostatic materials are applied to elongated and narrow bleeding surfaces, then hemostatic effect is achieved, but application difficulty increases and material waste occurs
Solution Approach 1:
The support material is designed as a mesh structure with interconnected strands that can be cut into segments of appropriate sizes for different wound dimensions, making application to elongated and narrow surfaces more manageable
Solution Approach 2:
The hemostatic material is applied locally to the bleeding surface through the mesh support structure, allowing precise placement on elongated and narrow surfaces without requiring excess material
2Ease of operation
If wax-like hemostatic materials are softened by warming and kneading, then applicability improves, but procedure complexity and time increase
Solution Approach 1:
The hemostatic material is formulated with modified rheological properties to achieve optimal consistency at room temperature, eliminating the need for warming and kneading while maintaining ease of application
Solution Approach 2:
The combination of hemostatic material with mesh support material creates a composite structure that provides both ease of handling and effective hemostatic performance without requiring thermal softening
3Productivity
If putty-like hemostatic materials are applied directly without warming, then procedure time decreases, but control over application precision is reduced
Solution Approach 1:
The mesh support material acts as an intermediary carrier that provides structural control and precision during application, while allowing the putty-like hemostatic material to be applied directly without warming
Solution Approach 2:
The mesh support structure is prepared in advance with appropriate dimensions and configuration, enabling precise application of the hemostatic material without requiring thermal softening or extensive manipulation
4Reliability
If hemostatic materials are applied to sharp bone surfaces, then hemostasis is achieved, but surgical gloves may be damaged
Solution Approach 1:
The mesh support material serves as a protective intermediary between the surgical material and sharp bone surfaces, preventing direct contact that could damage surgical gloves while allowing effective hemostatic application
