The invention discloses a medical device sterilizing device, which comprises a casing, and a baffle is fixedly connected to the left and right sides of the bottom of the inner wall of the casing, and the tops of the two baffles are fixedly connected by the baffle, and the bottom of the inner wall of the casing is located at two A mounting plate is fixedly connected between the baffles, and a rotating electric machine is fixedly connected to the top of the mounting plate, and a rotating rotating shaft is fixedly connected to the output shaft of the rotating electric machine. The invention provides a rotating electric machine, a rotating rotating shaft, a rotating box, a driving motor, a driving shaft, a fixing block, a rolling bearing, a rotating block, a rotating rod, a fixing sleeve, a sterilization box, a fixing clip, a first gear, a second gear, a water pipe and The nozzles cooperate with each other to make the disinfection effect ideal. When disinfecting, the static disinfection becomes dynamic disinfection, which can fully exert the disinfection characteristics of the disinfectant, which not only makes the disinfection more thorough, but also improves the disinfection rate and gives the hospital a medical work belt. Great convenience.
