Heart stent use alloy material free of ion precipitation

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 [0001] The invention relates to an alloy material. Background technique [0002] One in every 1 million people in the world is allergic to metals. Once allergies occur, it can cause contact dermatitis symptoms such as skin redness, itching, and yellow water around the contact. Once metal allergic dermatitis occurs, the most fundamental and effective way is to isolate the allergen. [0003] A heart stent is a medical device that requires long-term intervention in the heart and has physiological and mechanical functions consistent with the beating of the heart. It has a vital purpose for cardiac surgery and future stabilization of the condition. However, for many alloy stents, metal ions will be precipitated under the influence of static electricity in the body for a long time, which will affect the mechanical properties of the stent and bring great harm to the body, even life-threatening.
