Medical metal equipment
Due to the particularity of the use environment and required characteristics of medical devices, there are strict standards for the selection of Medical metal instruments’ material.
First of all, metal must be relatively malleable, and the malleability is strong to be easy to shape, but not too strong, because once the surgical instrument is formed, it needs to maintain its shape and not change easily. Depending on the type of equipment, the use of metal may need to be quite malleable, because many surgical instruments need to be long and thin in shape, such as scalpels, pliers, scissors, etc.
Secondly, the metal surface of the surgical instruments needs to be tough and shiny, so that the instruments are easy to clean, will not hide bacteria, and effectively prevent human wound infections.
Finally, the metal needs to not chemically react with human tissues, so that it will not cause any metal pollution to the human body during the operation.
