In 1847, Hungarian doctor Ignaz Semmelweis did the unthinkable: He suggested that washing your hands could help ward off diseases and viruses. He was ridiculed and ignored by many other doctors, but others took his suggestion and found out for themselves that the sanitary practice works.
Little did he know at the time, but this practice eventually led to the business of sterilization equipment. With more and specialty surgical tools being patented and made, sterilizing this equipment is a steadily growing business.
The 3 most reliable methods of sterilization are autoclaves, vaporized hydrogen peroxide sterilizers and plasma gas sterilizers. These are all time tested, proven and used in medical facilities worldwide.
There is no need to worry about the sanitary condition of the implements used in an operation, because it is now standard procedure to sanitize surgical equipment before every medical procedure.
