Specific application cases of non-magnetic stainless steel tubes in medical devices

Non-magnetic stainless steel tubes, with their advantages such as non-magnetism, corrosion resistance and biocompatibility, are widely used in medical devices. Here are some specific examples: 

The domestic heart stent is made of 1Cr18Mn18N fine wire braiding. By taking advantage of the non-magnetic property of this material, it avoids interference with medical devices near the heart. Meanwhile, its high strength enables the stent wall thickness to be reduced by 30% while maintaining the same radial support force, lowering the rate of restenosis of blood vessels to less than 5%. 

Orthopedic implants: Carpenter Biodur® 108 non-magnetic stainless steel has passed the ISO10993 biocompatibility test and is used to manufacture joint replacement components, spinal implants, bone plates and screws, etc. Its non-magnetic property can avoid affecting medical examinations and treatment processes, and it can remain stable for a long time in the human body environment and resist corrosion by body fluids. 

Medical gas pipeline system: Hospitals require safe and sterile media to transport gases such as oxygen, nitrous oxide and carbon dioxide. 316L non-magnetic stainless steel pipes are used because of their strong corrosion resistance, which can prevent the pipes from being corroded by impurities or disinfectants in the gas, ensuring no leakage and no contamination during gas transportation, and maintaining the purity and integrity of medical gases. 

MRI equipment accessories: MRI equipment has extremely high requirements for the magnetic field environment. Non-magnetic stainless steel tubes can be used to manufacture non-magnetic bolts, guide rails and other accessories for MRI scanners, which can avoid interfering with the equipment's magnetic field, ensure imaging quality, and at the same time be resistant to disinfectant corrosion, adapting to the medical environment. 

Dialysis equipment: During the hemodialysis process, it is necessary to ensure that the blood is filtered and circulated in a clean and uncontaminated environment. 316L non-magnetic stainless steel tubes, with their smooth surface which is less prone to bacterial growth and good corrosion resistance, can be used to manufacture the internal pipes of dialysis machines, ensuring the safety of the blood treatment process. 

Surgical instrument support: Some surgical instruments use non-magnetic stainless steel tubes as supports, such as some complex endoscope supports, etc. By taking advantage of their non-magnetic property, they can be used in conjunction with MRI and other equipment for real-time imaging during surgery, providing precise guidance for the operation. At the same time, their high strength and corrosion resistance can ensure that the instruments maintain stable performance during multiple uses and disinfections.
