Description

Technical Field

[0001] The utility model relates to the technical field of femoral stems, in particular to a disinfection device for a femoral stem before use. Background Art

[0002] As we all know, the existing femoral stem is a medical device, which is mainly used in total hip replacement surgery to play a stabilizing and supporting role. The femoral stem is made of cobalt-chromium-molybdenum alloy material and has a coating on the surface, such as hydroxyapatite, to improve the bonding strength with cancellous bone. After total hip replacement surgery, the early stability of the femoral stem prosthesis mainly depends on the press-fit bonding between the femoral stem and cancellous bone.

[0003] Before the existing femoral stem is used, there will be bacteria and biofilm formed by bacteria on the outer surface of the femoral stem. Medical staff usually use a brush to manually scrub it. This method reduces work efficiency, wastes a lot of manpower and is likely to result in incomplete disinfection, which in turn causes infection, resulting in low reliability of use. Therefore, a disinfection device for the femoral stem before use is proposed. Utility Model Content
