Have you ever seen such inconspicuous metal particles in your everyday life or general work environment? They are small in size and might be easily overlooked. However, these tiny metal particles have a remarkable "background" and serve important purposes.
These metal particles are made of platinum-iridium alloy material and are used as electrode materials. Platinum, as a precious noble metal, inherently possesses many unique physical and chemical properties. For example, it has good electrical conductivity, corrosion resistance, and stable chemical properties. Iridium is also a rare metal with excellent performance. When iridium is added to platinum in specific proportions, they fuse together to form this special platinum-iridium alloy material.
The platinum-iridium alloy material plays a crucial role in the medical field, especially in radiofrequency ablation catheters which are frequently used in modern medical interventional treatments. Radiofrequency ablation catheters are mainly used for treating various cardiac arrhythmias and other heart diseases. The function of the electrode material is indispensable in this process.
When the radiofrequency ablation catheter is accurately delivered to the lesion site through the blood vessels, the electrode material comes into action. It uses radiofrequency energy to rapidly increase the local temperature of the myocardial tissue, causing coagulative necrosis of the diseased myocardial tissue. This achieves the purpose of eliminating abnormal electrical activities and restoring normal cardiac rhythm. Due to its excellent electrical conductivity and stable performance, the platinum-iridium alloy material can ensure efficient and stable transmission of radiofrequency energy, making the treatment process safer and more effective.
Do not underestimate these small metal particles. They have a high value in the market. After going through multiple complex processing steps and strict quality inspections, each gram of the platinum-iridium alloy electrode material is worth about 200 yuan. This high price not only reflects the rarity of the material and the sophisticated manufacturing process but also highlights its vital role in the medical field. After all, it is related to the life, health, and treatment effectiveness of patients, and is one of the important supports for the continuous progress and development of modern medical technology.
