[0001] The application belongs to the technical field of medical instrument disinfection, and particularly relates to a gynecological disinfection device. BACKGROUND

[0002] In clinical diagnosis and treatment of gynecology, disinfection of medical instruments is a key link for preventing nosocomial infection. Gynecological medical instruments are various, including catheters, suction tubes with tubular structure and specula, surgical forceps with non-tubular structure, and the like. The surface and inner cavity of the instruments are prone to residual of body fluids, mucus and other pollutants. If disinfection is not thorough, cross infection is easily caused. At present, steam disinfection is widely used in gynecological medical instrument disinfection due to its high efficiency and environmental protection. However, there are still many problems to be solved in the actual application of the existing disinfection device.

[0003] (1) The disinfection of tubular gynecological medical instruments generally has the problem of incomplete cleaning of the inner wall. The existing device achieves disinfection through static steam fumigation, lacks an active cleaning mechanism for the inner wall of the tubular instrument, and only relies on steam flushing to clean stubborn stains.
