Abstract: An object to be sterilized is disposed inside a vacuum chamber, and the inside of the vacuum chamber is evacuated. When the pressure inside the vacuum chamber reaches 3 Pa, a cutoff valve disposed between the vacuum chamber and the vacuum pump is closed. High-frequency power is supplied to an electrode. Oxygen gas is introduced into the vacuum chamber for 0.1 sec. Thereafter, the pressure is held constant for 3 sec. Until the pressure inside the vacuum chamber reaches 10 kPa, introduction of oxygen gas into the vacuum chamber is repeated. When the pressure reaches 10 kPa, the cutoff valve is opened to evacuate the inside of the vacuum chamber and the supply of the high-frequency power is stopped. Introducing the oxygen gas and determining pressure inside the vacuum chamber is repeated, and after 90 min, the pressure inside the vacuum chamber is returned to atmospheric pressure.

The femoral component includes a femoral articular surface and a cam that is provided on the rear end of the femoral articular surface and protrudes from the femoral articular surface, the insert plate includes a tibial articular surface that makes contact with the femoral articular surface and a cam-receiving slide surface that makes contact with the cam.

Abstract: [Problems] To provide a radical sterilization apparatus which can generate hydroxy (OH) radical and oxygen (O) radical at a high density to thereby surely and economically sterilize a subject to be treated. [Means for Solving Problems] While maintaining a storage unit (1) in which a medical instrument (6) is stored at a low pressure by using a low pressure-maintaining unit (2), vapor is supplied from a vapor-supplying unit (3) into the storage unit (1). Then, oxygen in this vapor is converted into radicals by a radical-forming unit (4) to give hydroxy (OH) radical and oxygen (O) radical. Thus, the hydroxy (OH) radical and the oxygen (O) radical can be maintained each as a single radical over a long period of time and can be generated at a high density, which makes it possible to surely and economically sterilize the medical instrument (6).
