Ceramic Solutions for Medical instrumentation
Biocompatible is one of the inherent attributes of advanced ceramics; it is ideal for use in medical instruments and devices. In addition, advanced ceramics take advantage of their high strength, insulation, and resistance to corrosive environments, low weight, and customized complex geometries with high precision after machining. They help medical equipment to obtain more accurate diagnostic data, ensure the machine’s operation is more reliable, and prolong their service lifetime.
Industry Challenges in Medical Instruments and Devices
Traditional metal and high polymer materials encounter huge challenges in some medical instruments
● Poor chemical inertness: They are prone to corrosion and aging, even causing allergies because of the release of ions
● Insufficient abrasion resistance: they are easy to wear, especially in the sliding biological structures
● Low mechanical strength： high polymers can’t offer enough mechanical strength in demanding uses
● Electromagnetic: The magnetic property of metallic materials that can interfere with the imaging result because of artifacts
The shortages of these materials above can directly affect biosafety, long-term stability, and adaptability to extreme operating conditions.
Why Advanced Ceramics
Advanced ceramics possess intrinsic properties for engineered solutions to these challenges:
● Chemical stability: Don’t undergo chemical reactions in most acidic or alkaline conditions; they have excellent biocompatibility.
● Super wear resistance: They are much harder than metals and polymers, and have a low coefficient of friction.
● High mechanical strength: They offer unmatched hardness, compressive, flexural strength, and fracture toughness.
● Non-magnetic & image compatibility: All advanced ceramics are free of magnetic, It will not interfere with MRI and CT images.
