Phospholipid Bone Hemostasis: Resorbable Tamponade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone hemostatic agents, such as BoneWax, are non-resorbable and can interfere with bone repair and serve as infection loci, while biodegradable alternatives are costly to produce due to complex synthesis processes.
Innovation Solution
A phospholipid composition, primarily comprising phosphatidylcholine and optionally anti-infective agents, is used as a biocompatible and biodegradable mechanical tamponade to achieve hemostasis in bleeding bone, which can be produced at a lower cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beeswax-based BoneWax is used for bone hemostasis, then hemostatic effectiveness is improved, but biocompatibility deteriorates due to permanent foreign body presence and infection risk
Solution Approach 1:
The invention changes the chemical composition parameter from non-resorbable beeswax/paraffin to resorbable phospholipids (lecithin, phosphatidylcholine, phosphatidylethanolamine, phosphatidic acid, sphingomyelin). This parameter change maintains hemostatic effectiveness while adding biodegradability and biocompatibility, allowing the material to be naturally metabolized and eliminated from the body.
Solution Approach 2:
The invention employs a temporary, short-living hemostatic agent that fulfills its function and then naturally degrades. The phospholipid-based composition acts as a disposable material that provides hemostasis during the critical period and then is resorbable by the body, eliminating the need for permanent foreign body presence.
2Object-affected harmful factors
If resorbable or biodegradable formulations are used for bone hemostasis, then biocompatibility is improved, but manufacturing cost increases due to complex synthesis processes
Solution Approach 1:
The invention copies the natural phospholipid structure that already exists in biological systems (cell membranes), using materials that are naturally occurring or easily synthesized. By mimicking natural biomolecules, the invention achieves biocompatibility without requiring complex synthetic pathways, thereby reducing manufacturing costs.
Solution Approach 2:
The invention changes the material composition to phospholipids that can be obtained from natural sources (egg yolks, soybeans, animal tissues) or synthesized through simplified processes. This parameter change from complex synthetic polymers to naturally abundant phospholipids reduces both synthesis complexity and manufacturing cost while maintaining biodegradability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The phospholipid composition effectively stops bone bleeding, is resorbable, and provides antimicrobial activity, addressing the limitations of existing agents while being cost-competitive with beeswax-based products.
Implementation Method 1
hemostasis can be achieved in bleeding bone by mechanical tamponade of a putty or waxy like substance to fill pores of the bone, especially in cancellous bone, thus preventing the blood from continuing to flow out of the bone
Implementation Method 2
the phospholipid composition effectively stops bone bleeding, is resorbable
