Abstract
A bone substitute that drills and cuts like bone for use in training and testing comprising an inner core of a foamable polymer or other soft material and an outer shell of a polymer such as an epoxy resin with a particulate filler such as aluminum oxide or silicon carbide added thereto together with, in some cases, titanium oxide to form a slurry for casting or molding around the inner core. Also provided is a method for making the bone substitute.
Claims3
A bone substitute useful as a bone model for teaching and training students and for testing surgical equipment, the bone substitute comprising:
- an inner core comprising a foamable polymer;
- and
- an outer shell formed around the inner core, the outer shell comprising an epoxy resin and silicon carbide (SiC) added to the epoxy resin.
A bone substitute useful as a bone model for teaching and training students and for testing surgical equipment, the bone substitute comprising:
- an inner core comprising a foamable polymer;
- and
- an outer shell formed around the inner core, the outer shell comprising a polymer, and silicon carbide (SiC) and titanium oxide (TiO) added to the polymer to form a slurry for casting or molding around the inner core, said bone substitute exhibiting properties substantially like real bone useful for training and testing.
A bone substitute comprising:
- an inner core comprising a foamable polymer;
- and
- an outer shell formed around the inner core, the outer shell comprising an epoxy resin and from 2.5% to 30% by weight of silicon carbide (SiC) and from 20% to 45% by weight of titanium oxide (TiO) added to the epoxy resin to form a slurry for casting or molding around the inner core, said bone substitute exhibiting properties substantially like real bone useful for training and testing.
