Abstract
The invention discloses a heart stent use alloy material free of ion precipitation, and the heart stent use alloy material comprises the following components by weight: 100 parts of titanium, 30-40 parts of ruthenium, 15-23 parts of germanium, 10-17 parts of niobium, 5-9 parts of palladium and 1-4 parts of molybdenum. The heart stent use alloy material free of ion precipitation is more stable in lattice structure, suitable for the human environment, and free of ion precipitation.
Description
Technical field
The present invention relates to a kind of alloy material.
Background technology
Every 1,000,000 people just have one to cause allergy because of metal in the world.Once occur irritated, contact red swelling of the skin around, itch can be caused, drop down the performance of the contact dermatitis such as yellow water.Once there is metal allergy dermatitis, the most basic and effective way is isolated allergen.
Cardiac stent a kind ofly needs to get involved for a long time in heart and have the medical instruments of the physiology mechanical function meeting heartbeat, has vital object for heart operation and stable disease in the future.But a lot of alloy bracket, under the effect due to environment such as long-time electrostatic in vivo, has metal ion and separates out, affect the mechanical property of support, also can bring very large harm to health, even occur life danger.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of cardiac stent alloy material with antianaphylaxis function.
Object of the present invention carrys out specific implementation by the following technical programs:
Without a cardiac stent alloy material for elemental release, each element by weight, titanium 100 parts, ruthenium 30-40 part, germanium 15-23 part, niobium 10-17 part, palladium 5-9 part, molybdenum 1-4 part.
Preferably, the above-mentioned cardiac stent alloy material without elemental release, each element by weight, titanium 100 parts, ruthenium 34 parts, 17 parts, germanium, niobium 15 parts, palladium 5.5 parts, molybdenum 2 parts.
Beneficial effect of the present invention:
Cardiac stent alloy material without elemental release provided by the present invention, crystalline network is more stable, is adapted to the environment of human body, there will not be the precipitation problem of ion.
