Reducers play a key role in medical devices, ensuring stable operation by precisely controlling speed and increasing torque. In the surgical robot, the reducer makes the robotic arm move accurately and improves the success rate of surgery. CT and MRI scanners use a reducer to control the scanning platform and ensure image quality. In radiation therapy equipment, speed reducers pinpoint radioactive sources to reduce damage to healthy tissue. The medical beds and nursing equipment use speed reducers to achieve smooth movement and improve patient comfort. In addition, drug delivery systems and laboratory automation equipment also rely on reducers to control delivery speed and accuracy. The reliability and durability of reducers are critical to improving the performance of medical devices and providing safer and more efficient medical services to patients.
