Abstract
A sterilization unit for dental handpieces and other instruments, and which finds utility in the sterilization of any surgical instrument, or the like, which breaks the skin or comes into contact with body fluids, and which are too delicate or have sharp edges which could become damaged in conventional present day autoclaves. The sterilization unit of the present invention combines heat, steam pressure and time in a precisely controlled manner so that the handpieces, or other surgical instruments are not damaged during the sterilization procedure. This is achieved by providing a total cycle time including cooling to a patient-ready condition of less than 20 minutes. A unique control system places the sterilizing chamber at a temperature which creates steam and pressure in a time frame that sterilizes the handpiece without damage to the turbine. Mineral-free water is flushed through the piping and turbine to clear out debris and insure sterilization and de-scaling of the inside as well as outside of each handpiece.
