[0038] Working principle: when the device is in use, first manually open the box door 25 and pull the placement plate 4 out of the track, then place the cleaned scalpel, hemostatic forceps and other medical instruments to be sterilized on the placement plate 4, and push them back into the cleaning box after placement. When pushed to the deepest position, press the fixing cover 6 downward by hand, and the fixing cover 6 moves downward under the downward pressure, and the fixing cover 6 drives the fixing block 11 to move downward, and the fixing block 11 drives the clamping piece 12 to move downward. At this time, manually pull the pull rod 16, and the pull rod 16 drives the clamping block 14 to retract into the installation groove. When the clamping piece 12 moves to the lowest point, release the pull rod 16. At this time, the elastic force of the reset spring 17 drives the limiting piece 15 to move, and the limiting piece 15 drives the clamping block 14 to move, reset the clamping block 14 and insert it into the card interface, fix the clamping piece 12, and then fix the fixing cover 6, repeat the above operation, put the remaining medical instruments that need to be sterilized on another placement plate 4 and fix them, and then close the box door 25 to start sterilization.

[0039] First, the ultraviolet lamp 23 is started through the control panel 24, and the ultraviolet lamp 23 disinfects one side of the medical devices on the two placement plates 4. When the appropriate position is reached, the drive motor 22 is started to rotate through the control panel 24, and the output end of the drive motor 22 drives the drive gear 19 to rotate, and the drive gear 19 drives the two transmission gears 20 to rotate. The two transmission gears 20 respectively drive the two slide rails 3 to move through the rotating shaft 2, so that the two slide rails 3 are turned over at the same time, driving the two fixed covers 6 to approach the ultraviolet lamp 23, and flip the medical devices fixed therein. The drive motor 22 is stopped, and the area on the other side that has not been irradiated is irradiated to fully disinfect the medical devices.

[0040] After the prescribed time of disinfection, turn off the ultraviolet lamp 23 through the control panel 24, manually open the box door 25, and pull the pull rod 16 by hand. The pull rod 16 drives the card block 14 to shrink and disengage from the card interface. At this time, the elastic force of the two lifting springs 10 drives the two sliders 8 to approach each other, and the two sliders 8 respectively drive the two support rods 9 to move. The two support rods 9 drive the fixed cover 6 to move upward under the joint action of the four limit rods 5, so that the fixed cover 6 is separated from the placement plate 4 and the placement plate 4 is released. The placement plate 4 is pulled out to take out the medical device that has been disinfected, and the disinfection of the medical device is completed.

[0041] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes.
