DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 3 In an embodiment of the present invention, a disinfection device for orthopedic screws includes a shell 1, an upper cover 2 is assembled and connected on the shell 1, the shell 1 and the upper cover 2 are assembled by snapping, a connecting flange can be arranged between the shell 1 and the upper cover 2, and they are assembled by bolt connection, the lower part of the shell 1 is in a contracted state, and an accommodating space is formed between the shell 1 and the upper cover 2, a fixing frame 3 is fixedly connected and arranged below the shell 1 and connected to the upper cover 2, a placement mechanism 4 is rotatably connected and arranged on the fixing frame 3, a rotating ring 9 for driving the placement mechanism 4 to flip in the fixing frame 3 is rotatably connected and arranged on the outer periphery of the shell 1, an atomizer 5 is installed at the bottom of the shell 1, a sewage pipe 8 is also connected to the bottom of the shell 1 on one side of the atomizer 5, and a liquid level meter 7 for observing the liquid level depth in the shell 1 is installed at the bottom of the shell 1.

[0027] During use, the screws to be disinfected are placed on the placement mechanism 4. After being fixed, the disinfectant liquid can be sprayed upwards through the atomizer 5. In order to better disinfect the screws placed on the placement mechanism 4, a fan 6 is also installed between the atomizer 5 and the placement mechanism 4 in the housing 1. The fan 6 is a waterproof fan. The output direction of the fan 6 is to transport from the atomizer 5 to the placement mechanism 4 side. When the fan 6 is started, the atomized liquid can be blown onto the placement mechanism 4 so as to disinfect the screws. During the disinfection process, the liquid dripping downwards on the placement mechanism 4 can be discharged centrally through the drain pipe 8. The drain pipe 8 is preferably provided with a valve for centralized discharge. In order to control the liquid level in the housing 1 not to exceed the output end of the atomizer 5, the liquid level meter 7 provided at the bottom of the housing 1 can conveniently observe the liquid level. When it is close to the output end of the atomizer 5, the valve on the drain pipe 8 is controlled to discharge to avoid affecting the effect of atomization disinfection. In order to ensure that multiple surfaces of the screw can be efficiently disinfected, the placement mechanism 4 can be rotated on the fixed frame 3, and the rotation of the rotating ring 9 can drive the placement mechanism 4 to flip on the fixed frame 3. According to needs, the rotating ring 9 can be connected to a slow-speed motor to flip the placement mechanism 4 at intervals, thereby completing the multi-sided disinfection of the screw. Different surfaces of the screw can directly face the output direction of the fan 6, thereby avoiding dead corners for disinfection and minimizing the waste of disinfectant solution. Moreover, no manual control of the flipping is required during the entire process, and through the cooperation of the rotating ring 9, the placement mechanism 4 can be kept horizontal for a longer time during rotation, so that the surface of the screw on the placement mechanism 4 can be fully in contact with the solution. After quickly flipping the placement mechanism 4, the other surface can be fully disinfected, and the disinfection efficiency is higher.

[0028] Among them, Figure 1 and Figure 2As shown, the fixed frame 3 is a square frame-shaped structure, the four corners of the fixed frame 3 are chamfered, and are assembled and connected to the inner wall of the shell 1 through a mounting pad 31. A placement hole 32 is provided through the middle of the fixed frame 3, and the placement mechanism 4 is rotatably connected in the placement hole 32. The setting of the fixed frame 3 is convenient for disassembly and maintenance. The placement mechanism 4 includes a rotating frame 41 rotatably connected in the placement hole 32, and the two ends of the rotating frame 41 are symmetrically connected with a driving shaft 44 that passes through the fixed frame 3 and the shell 1. The driving shaft 44 and the shell 1 and the fixed frame 3 are all rotatably connected through bearings. The rotating frame 41 is rotatably connected in the placement hole 32 through the driving shaft 44. A plurality of sets of swing mechanisms 46 are movably connected in the rotating frame 41, and threaded mounting holes 42 are embedded in the four corners of the rotating frame 41. The rotating frame 41 is covered with a mesh frame, and the corners of the mesh frame It is assembled on the threaded mounting hole 42 by bolts, and a gauze with a certain elasticity is provided in the mesh frame. The mesh frame cooperates with the swing mechanism 46 to carry and place the screws. When placing, it is only necessary to place the screws on the swing mechanism 46, and then cover the mesh frame on the screws, and assemble and connect them with the threaded mounting hole 42 by bolts. The operation is simple and convenient, and will not affect the disinfection use of the screws. At the same time, it will not affect the subsequent shaking of the swing mechanism 46. During the shaking process of the swing mechanism 46, the screws can also be fully contacted with the atomized liquid medicine, thereby ensuring the comprehensiveness of the disinfection.

[0029] In this scheme, if Figure 3-Figure 6 As shown, the swing mechanism 46 includes a swing shaft 4601 rotatably connected in the rotating frame 41, and multiple groups of parallel thin rods 4603 are symmetrically connected on both sides of the swing shaft 4601. The thin rods 4603 on adjacent swing shafts 4601 are staggered. Side grooves 43 are symmetrically penetrated on both sides of the rotating frame 41, and swing blades 4602 are symmetrically fixedly connected on both sides of the outer periphery of the end of the swing shaft 4601 extending into the side groove 43. The swing blades 4602 are arranged as thin sheets, so that when the atomized airflow blows up, the swing shaft 4601 can be driven to swing through the swing blades 4602, and the adjacent thin rods 4603 can cooperate to carry screws, and then as the screws are driven to swing and stagger, each position on the screw can be exposed and contact the atomized liquid, thereby improving the disinfection efficiency.

[0030] Furthermore, the swing shaft 4601 passes through part of the outer movable sleeve of the rotating frame 41 and is provided with a rotating sleeve 4604, and a sliding groove 4605 with a fan-shaped structure is provided on the rotating sleeve 4604. A limit slider 4606 slidably matched with the sliding groove 4605 is fixedly connected to the outer periphery of the swing shaft 4601, and the limit slider 4606 can swing in the sliding groove 4605 when the swing shaft 4601 rotates, and the sliding groove 4605 can limit the rotation angle of the limit slider 4606 and the swing shaft 4601, thereby avoiding the problem of the screw being stuck or falling from the gap between the adjacent thin rods 4603 due to excessive rotation angle.

[0031] like Figure 7-Figure 8 As shown, a block 45 is fixedly connected to the end of the driving shaft 44, and V-grooves 91 corresponding to the block 45 are symmetrically embedded on both sides of the rotating ring 9. The depth of the V-groove 91 is half of the difference between the diagonal length of the cross section of the block 45 and the height of the block 45. The arcs on both sides of the V-groove 91 coincide with the movement trajectory of the side of the block 45 when it rotates, that is, when the rotating ring 9 rotates, the lower surface of the block 45 is attached to the upper surface of the rotating ring 9, and the block 45 uses the driving shaft 44 to keep the screw carried by the swing mechanism 46 on the same side facing the sprayed atomized liquid, and when the V-groove 91 rotates to correspond to the block 45, the block 45 can rotate, thereby driving the screw to turn over. In this process, the screw has a stable spray disinfection process, and then quickly turns over and continues to spray disinfect stably, which can not only fully disinfect, but also ensure that a single side has sufficient disinfection time.

[0032] The above process is based on the fact that the horizontal maintenance effect of block 45 is not good. When the V-groove 91 is aligned with block 45, block 45 automatically rotates and is then driven by the V-groove 91 to achieve flipping. However, this is random. Therefore, on the basis of the above, further, the upper surface of the rotating ring 9 is located on one side of the V-groove 91 and is embedded with a groove 92. A rotating plate 93 is rotatably connected in the groove 92. A torsion spring is connected between the rotating plate 93 and the groove 92. The torsion spring acts on the end of the rotating plate 93 close to the V-groove 91 to extend upward from the groove 92. The rotating ring 9 can be rotated manually, or a belt or gear transmission can be set on the periphery, and the rotating ring 9 can be driven to rotate by a slow motor. When the rotating ring 9 rotates, the rotating plate 93 first contacts the block 45, and the rotating plate 93 is pressed into the embedded groove 92 by the block 45. The block 45 cannot rotate at this time because it fits the upper surface of the rotating ring 9. When the block 45 moves relatively to between the embedded groove 92 and the V groove 91, one side corner of the block 45 is located above the V groove 91, and the other side is located above the end of the rotating plate 93. The rotating plate 93 drives the block 45 to tilt under the action of the torsion spring, so that the block 45 flips over to realize the turning over of the screw. The whole process is stable and efficient, and can be automated. At the same time, compared with the traditional incomplete gear intermittent transmission, this method is more stable in each process.

[0033] A method for disinfecting orthopedic screws, using the above device, comprises the following steps: S1, place the screws on the placement mechanism 4, cover the net frame, and cover the upper cover 2 on the housing 1; S2, close the valve on the sewage pipe 8, start the fan 6 and the liquid level meter 7 to spray and disinfect the screws; S3, manually or electrically rotating the rotating ring 9, intermittently driving the placement mechanism 4 to rotate; during the disinfection process, observe the liquid level display of the liquid level meter 7, if the liquid level is close to the output end of the atomizer 5, open the valve of the sewage pipe 8 to discharge the waste liquid; S4, after the disinfection is completed, the fan 6 and the liquid level meter 7 are turned off, the rotating ring 9 is stopped and the valve of the sewage pipe 8 is opened, and then the upper cover 2 is opened, the screws are removed from the placement mechanism 4, and then it is determined whether to perform subsequent processing according to needs.
