motors in surgical special equipment must be operated under very harsh conditions
One of the biggest challenges DC drives face in the operating room is the need for constant disinfection. Because during the operation, all instruments that come into contact with the patient must be strictly sterilized, and most of the disinfection is steam sterilization. During the sterilization process, the instrument is continuously heated at 134 degrees Celsius for 20 minutes in an autoclave at a pressure of 2.3 bar and 100% air humidity. According to Anthony Mayr, the latest test results show that by carefully selecting materials and protecting critical components (such as protecting the rotor with a vacuum seal), it is possible to manufacture motors that can withstand more than 2000 steam sterilizations. At the same time, future drives will be smaller, lighter, and more performant, which will help surgeons perform surgical procedures more accurately and efficiently, and patients will be able to return to health more quickly.
