Dental Needle Uses: Dental, ENT, and E-Commerce
Divided into two categories according to the speed: high-speed dental bur (more than 100,000 revolutions, dental general in 30-45 million revolutions of the second type of medical equipment), low-speed dental bur (≤ 30,000 revolutions of a medical device)
Medical device classification rules:
A type of medical device: medical equipment that can ensure its safety and effectiveness through routine management, vice: surgical caps, masks, medical X-rays, etc.
Class II medical devices: Medical devices that are in direct contact with human blood or human body fluids, invade human tissue but do not stay in the body or stay for a short time, and should be controlled for their safety and effectiveness.
