In the medical field, various precision instruments and equipment have extremely stringent requirements for the performance of their components. Take artificial joints as an example: the manufacturing of their key components often utilizes advanced processes similar to powder metallurgy. By precisely pressing and sintering medical metal powders (such as titanium alloy powders), components with specific porous structures and good biocompatibility can be produced. These components not only need sufficient strength to support human movement but also require excellent wear resistance to ensure long-term reliability.



Key transmission components of surgical robots can also draw on the self-lubricating concept of oil-impregnated powder metallurgy bearings. By using special medical alloy powders to create transmission parts with a porous structure filled with medical-grade lubricating oil, during a surgical robot’s operation, frictional heat and mechanical action between components release the lubricating oil to achieve self-lubrication. This reduces the contamination risks associated with external lubrication while ensuring high-precision and stable transmission, enabling surgical robots to operate accurately and smoothly in high-precision medical procedures such as minimally invasive surgery, enhancing both the safety and effectiveness of surgeries.



Additionally, in some portable medical testing devices, miniature and low-maintenance moving components can also benefit from similar technologies. For example, the core components of micro-pumps, using self-lubricating parts made with powder metallurgy, can reliably transport testing reagents for long periods without the need for frequent maintenance or additional lubricants, ensuring continuity and accuracy in testing processes and supporting the efficient operation of medical diagnostics.
