[0002] Joint replacement surgery is one of the most demanding surgeries in terms of aseptic quality among all level 4 surgeries. In order to avoid repeated surgeries, joint dysfunction, and even amputation caused by infection after joint replacement surgery, joint replacement surgery is now paying more and more attention to how to avoid intraoperative surgical field contamination.

[0003] During knee replacement surgery, an oscillating saw is used. When cutting bones, bone fragments, body fluids, etc. will splash. Some of the fragments may splash onto the doctor's face and rebound into the surgical field of view or even the incision. Since the area above the doctor's shoulders is a non-sterile area, this may cause debris with bacteria to contaminate the incision. The current response measures at home and abroad are for doctors to wear medical personal protection systems, similar to "space suits", consisting of helmets, hoods, gowns, and batteries.
