Description

Technical Field

[0001] This utility model belongs to the field of orthopedic screw disinfection technology, specifically a medical orthopedic screw disinfection device. Background Technology

[0002] With the development of modern medicine, the number and complexity of orthopedic surgeries are constantly increasing. As an indispensable medical device in surgeries such as internal fixation of fractures and joint reconstruction, the use of orthopedic screws has also increased significantly. They are mainly used in the treatment of various traumas, degenerative diseases, deformity correction and other orthopedic conditions. Precise and sterile screw implantation plays a key role in the success of the surgery and the patient's recovery, which puts forward higher requirements for the sterilization and supply of screws.

[0003] Traditional immersion sterilization involves placing orthopedic screws in a container of disinfectant for a certain period of time. However, this method makes it difficult to ensure that all surfaces of the screw, especially the internal threads and deep holes, are fully exposed to the disinfectant. This results in incomplete sterilization in some areas, leaving residual bacteria or viruses and increasing the risk of surgical infection. Furthermore, the screws are easily contaminated with pollutants from the container rim when removed after immersion, and are also susceptible to recontamination during transfer to a sterile operating area.

[0004] Therefore, this utility model provides a medical orthopedic screw disinfection device. Utility Model Content

[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a medical orthopedic screw disinfection device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A medical orthopedic screw disinfection device of this utility model includes a disinfection box body; a disinfection container body is fixedly connected to the top of the disinfection box body; a sealing plate is rotatably connected to the side wall of the disinfection box body; a liquid storage box is fixedly connected to the top of the liquid storage box; a discharge port is detachably connected to the top of the liquid storage box; multiple flexible tubes are fixedly connected to the side wall of the liquid storage box, evenly distributed; a sealing cap is rotatably connected to the top of the disinfection box body near the liquid storage box; multiple rotating shafts are rotatably connected to the ends of the flexible tubes away from the liquid storage box, evenly distributed; a roller is fixedly connected to the middle of the rotating shaft; multiple brushes are fixedly connected to the middle of the roller, evenly distributed; multiple driven gears are fixedly connected to the ends of the rotating shafts away from the flexible tubes, and a DC motor is fixedly connected to the side wall of the driven gear located in the middle; two sliding grooves are opened on the side wall of the disinfection box body near the driven gear, forming a... The device is designed with the following configuration: a first sleeve is fixedly connected to the middle of the groove near the driven gear; two telescopic rods are slidably connected to the middle of the first sleeve, arranged symmetrically; multiple limiting rods are fixedly connected to the side wall of the DC motor away from the telescopic rods, evenly distributed and penetrating the groove; this step, by installing limiting rods to limit the screw, and then using a brush to clean it, ensures that all surfaces of the screw, including the head and threaded parts, can be thoroughly cleaned and disinfected. The rotation of the brush allows the disinfectant to be evenly distributed on the screw surface, and the friction between the brush and the screw can effectively remove stubborn stains and bacteria attached to the screw surface. Compared with traditional soaking disinfection or simple wiping disinfection, it can disinfect more thoroughly, reduce the risk of surgical infection, and the adjustable spacing of the limiting rods makes the device applicable to orthopedic screws of different sizes, improving the versatility and practicality of the device.

[0007] Preferably, the disinfection box body has two symmetrically arranged grooves near the center of the disinfection box body; two sets of second springs are fixedly connected to the center of the grooves, also symmetrically arranged; a filter plate is fixedly connected to the bottom of the second springs; a placement component is detachably connected to the top of the filter plate; a fixing plate is fixedly connected to the bottom of the filter plate near the sealing plate; multiple first springs are fixedly connected to the top of the fixing plate, equidistantly distributed; a baffle is fixedly connected to the top of the first springs; and a vibration motor is fixedly connected to the bottom of the filter plate, located at the center. This step, through the structural design of the filter plate and the vibration motor working together, reduces the amount of waste disinfectant adsorbed on the screw surface, thus preventing the screws from being used directly. At the same time, by allowing the disinfectant to fall through the filter holes of the filter plate to the bottom of the disinfection box body, it also reduces the accumulation of disinfectant on the top of the placement component.

[0008] Preferably, the placement assembly includes: a placement box, a base plate, and buckles; the base plate is hinged to the end of the placement box away from the sealing plate; two buckles are fixed to the side wall of the base plate near the placement box, arranged symmetrically; two slots are formed on the side wall of the placement box near the buckles; the buckles and slots cooperate with each other; this step, through the structural design of the buckles and slots, can conveniently collect screws, and the cooperation of the buckles and slots can ensure the sealing of the placement box, preventing screws from accidentally falling out of the placement box. When screws need to be stored, the bottom plate can be opened to easily pour out the screws, without having to reach in and grab them or use other tools to take them out as with traditional closed containers, greatly improving the convenience and efficiency of retrieval.

[0009] Preferably, a guide plate is fixedly connected to the center of the disinfection box body away from the placement box; a water outlet is opened on the side wall of the disinfection box body near the placement box; a drain pipe is fixedly connected to the center of the water outlet; this step, through the structural design of installing the guide plate and the drain pipe, can quickly and effectively discharge the used disinfectant from the disinfection cabinet, saving drainage time and improving the working efficiency of the disinfection device. Moreover, the inclined guide plate and the one-way sliding groove and drain pipe design effectively prevent the discharged disinfectant from flowing back into the disinfection cabinet, ensuring that the inside of the disinfection cabinet remains relatively dry and clean after drainage.

[0010] Preferably, the bottom of the disinfection box body near the guide plate is detachably connected to multiple second sleeves, which are symmetrically arranged; a collection box is slidably connected to the middle of the second sleeves; this step, through the structural design of installing multiple second sleeves, can prevent secondary contamination caused by screws coming into contact with each other or with the external environment during storage, ensuring that each screw remains sterile during use, reducing the risk of postoperative infection for patients, and also facilitating medical staff to quickly identify and accurately use the required screws during surgery, effectively shortening the operation time and improving the efficiency of surgery.

[0011] Preferably, the disinfection box body has multiple partitions fixed to the bottom near the second sleeve, which are evenly distributed. This step, through the structural design of installing multiple partitions, can play a role in physical isolation, so that the second sleeves of different specifications can be accurately positioned in a specific area, avoiding the misalignment of the collection box due to shaking, collision or other reasons during the collection and storage process.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The medical orthopedic screw disinfection device of this utility model, with its structure design of limiting the screw by installing a limiting rod and then cleaning it with a brush, can ensure that all surfaces of the screw, including the head and threaded parts, can be thoroughly cleaned and disinfected. The rotation of the brush allows the disinfectant to be evenly distributed on the screw surface, and the friction between the brush and the screw can effectively remove stubborn stains and bacteria attached to the screw surface. Compared with traditional soaking disinfection or simple wiping disinfection, it can disinfect more thoroughly, reduce the risk of surgical infection, and the adjustable spacing of the limiting rod makes the device applicable to orthopedic screws of different sizes, improving the versatility and practicality of the device.

[0014] 2. The medical orthopedic screw disinfection device of this utility model, through the structural design of using a filter plate and a vibration motor, reduces the amount of waste disinfectant adsorbed on the screw surface, thus making the screw difficult to use directly. At the same time, by allowing the disinfectant to fall through the filter holes of the filter plate to the bottom of the disinfection box body, it also reduces the accumulation of disinfectant on the top of the placement components.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 3As shown in the embodiment of this utility model, a medical orthopedic screw disinfection device includes a disinfection box body 1; a disinfection container body 11 is fixedly connected to the top of the disinfection box body 1; a sealing plate 115 is rotatably connected to the side wall of the disinfection box body 1; a liquid storage box 12 is fixedly connected to the top of the disinfection container body 11; a discharge port 17 is detachably connected to the top of the liquid storage box 12; multiple flexible tubes 13 are fixedly connected to the side wall of the liquid storage box 12, and are evenly distributed; a sealing cover 16 is rotatably connected to the top of the disinfection container body 11 near the liquid storage box 12; multiple rotating shafts 113 are rotatably connected to the ends of the flexible tubes 13 away from the liquid storage box 12, and are evenly distributed; a roller 18 is fixedly connected to the middle of the rotating shaft 113; the roller 18... Multiple brushes 19 are fixedly connected to the middle of the cylinder 18, and are evenly distributed. Multiple driven gears 14 are fixedly connected to the end of the rotating shaft 113 away from the hose 13, and a DC motor 15 is fixedly connected to the side wall of the driven gear 14 located in the middle. Two sliding grooves are opened on the side wall of the disinfection box body 11 near the driven gear 14, and are symmetrically arranged. A first sleeve 110 is fixedly connected to the middle of the sliding groove near the driven gear 14. Two telescopic rods 111 are slidably connected to the middle of the first sleeve 110, and are symmetrically arranged. Multiple limiting rods 112 are fixedly connected to the side wall of the telescopic rods 111 away from the DC motor 15, and are evenly distributed and pass through the sliding groove. When working, the DC motor 15 is started. The driven gear 14 in the middle is driven to rotate. Since the driven gear 14 is meshed, its rotation drives the gears on both sides to rotate synchronously. At this time, the distance between the sliding rods can be manually adjusted to accommodate screws of different sizes. When the screw is stuck in the middle of the limiting rod 112, the disinfectant in the middle of the storage box 12 can flow through the hose 13 to the middle of the rotating shaft 113. The rotating shaft 113 has a small hole in the middle, through which the disinfectant can wet the brush 19 to clean the screw. After cleaning, the distance between the limiting rods 112 is adjusted so that the screw falls through the discharge port 17 at the bottom of the disinfection box body 11 into the middle of the disinfection box body 1 for subsequent operations. This step is achieved through the installation of a safety device. The design of using a limiting rod 112 to limit the screw and then using a brush 19 to clean it ensures that all surfaces of the screw, including the head and threaded parts, are thoroughly cleaned and disinfected. The rotation of the brush 19 allows the disinfectant to be evenly distributed on the screw surface, and the friction between the brush 19 and the screw effectively removes stubborn stains and bacteria adhering to the screw surface. Compared with traditional soaking disinfection or simple wiping disinfection, it can disinfect more thoroughly, reduce the risk of surgical infection, and the adjustable spacing of the limiting rod 112 makes the device suitable for orthopedic screws of different sizes, improving the versatility and practicality of the device.

[0027] like Figure 2 and Figure 5As shown, the disinfection box body 1 has two symmetrically arranged grooves 24 near the center of the disinfection box body 11; two sets of second springs 25 are fixedly connected to the center of the grooves 24; a filter plate 2 is fixedly connected to the bottom of the second springs 25; a placement component is detachably connected to the top of the filter plate 2; a fixing plate 21 is fixedly connected to the bottom of the filter plate 2 near the sealing plate 115; multiple first springs 22 are fixedly connected to the top of the fixing plate 21, evenly distributed; a baffle 23 is fixedly connected to the top of the first springs 22; a vibration motor 26 is fixedly connected to the bottom of the filter plate 2, located at the center; during operation, the screw is placed inside the disinfection box body 1, at which time the screw is in contact with the placement component. After the screw is placed, the vibration motor 26 is started, which allows the vibration motor 26 to drive the filter plate 2 to rotate. The inside of the disinfection box body 1 vibrates. At the same time, as the filter plate 2 vibrates, the screws placed on top of the filter plate 2 will vibrate synchronously, shaking off the disinfectant adsorbed on the surface of the screws. The falling disinfectant will pass through the filter holes on the surface of the filter plate 2. At this time, the waste disinfectant will drip to the bottom of the disinfection box body 1. As the vibration motor 26 continues to run, the disinfectant adsorbed on the surface of the screws will be continuously vibrated and dripped off. This step, through the structural design of the filter plate 2 and the vibration motor 26 working together, reduces the amount of waste disinfectant adsorbed on the surface of the screws, thus reducing the difficulty of using the screws directly. At the same time, by allowing the disinfectant to fall through the filter holes of the filter plate 2 to the bottom of the disinfection box body 1, it also reduces the accumulation of disinfectant on the top of the placement components.

[0028] like Figure 5 As shown, the placement assembly includes: a placement box 3, a base plate 31, and buckles 32; the base plate 31 is hinged to the end of the placement box 3 away from the sealing plate 115; two buckles 32 are fixedly connected to the side wall of the base plate 31 near the placement box 3, arranged symmetrically; two slots are formed on the side wall of the placement box 3 near the buckles 32; the buckles 32 cooperate with the slots; during operation, because the base plate 31 is hinged, when the screw falls to the middle of the placement box 3, the buckles 32 can be pushed to the middle of the slots, so that the base plate 31 is tightly connected to the placement box 3. When screws need to be stored separately, the bottom plate 31 can be opened to empty the screws. This step is made convenient to collect screws through the structural design of the buckle 32 and the slot. The cooperation of the buckle 32 and the slot can ensure the sealing of the storage box 3 and prevent the screws from accidentally falling out of the storage box 3. When the screws need to be stored, the bottom plate 31 can be opened to easily empty the screws. Unlike traditional closed containers, there is no need to reach in to grab them or use other tools to take them out, which greatly improves the convenience and efficiency of retrieval.

[0029] like Figures 1 to 3As shown, a guide plate 4 is fixedly connected to the middle of the disinfection box body 1 away from the placement box 3; a water outlet 42 is opened on the side wall of the disinfection box body 1 near the placement box 3; a drain pipe 41 is fixedly connected to the middle of the water outlet 42; during operation, after the screws are disinfected, the used disinfectant will flow through the filter holes opened in the middle of the filter plate 2 to the top of the guide plate 4. Since the guide plate 4 is inclined, the disinfectant will flow along the inclined surface. The groove opened in the middle of the guide plate 4 further guides the flow of the disinfectant, so that it can be more concentrated and orderly directed towards a specific direction. The disinfectant flows in a directional direction and is eventually discharged through the filter plate 2 at the end of the chute into the externally connected drain pipe 41, and then discharged from the drain pipe 41. This step, through the structural design of the installation of the guide plate 4 and the drain pipe 41, can quickly and effectively discharge the used disinfectant from the disinfection cabinet, saving drainage time and improving the working efficiency of the disinfection device. In addition, the inclined guide plate 4 and the one-way chute and drain pipe 41 design effectively prevent the discharged disinfectant from flowing back into the disinfection cabinet, ensuring that the inside of the disinfection cabinet remains relatively dry and clean after drainage.

[0030] like Figure 4 and Figure 6 As shown, the bottom of the disinfection box body 1 near the guide plate 4 is detachably connected to multiple second sleeves 5, arranged symmetrically; a collection box 51 is slidably connected to the middle of the second sleeve 5; during operation, screws of different specifications are placed in different second sleeves 5 to achieve classified management of screws. The size, shape and internal structure of the collection box 51 can be customized according to the characteristics of different specifications of screws to better accommodate and fix the screws, and prevent the screws from colliding, squeezing or tangling with each other during storage. This step, through the structural design of installing multiple second sleeves 5, can prevent secondary contamination caused by screws contacting each other or contacting the external environment during storage, ensuring that each screw remains sterile during use, reducing the risk of postoperative infection for patients, and also making it convenient for medical staff to quickly identify and accurately use the required screws during surgery, which can effectively shorten the operation time and improve the efficiency of surgery.

[0031] like Figure 6 As shown, multiple partitions 6 are fixed to the bottom of the disinfection box body 1 near the second sleeve 5, and are evenly distributed. During operation, the partitions 6 can divide the space inside the disinfection box body 1 into multiple areas in the horizontal direction. Each area corresponds to the placement of screw collection boxes 51 of different specifications. This step, through the structural design of installing multiple partitions 6, can play a role in physical isolation, so that the second sleeves 5 of different specifications can be accurately positioned in specific areas, avoiding the misalignment of the collection boxes 51 due to shaking, collision, or other reasons during the collection and storage process.

[0032] like Figure 6As shown, the placement box 3 is made of nylon. During operation, the nylon placement box 3 has good flexibility and elasticity. This step is achieved by designing the placement box 3 as a nylon material. Because the surface of nylon is relatively smooth, the coefficient of friction is low when it comes into contact with the screw, which can effectively reduce the wear on the screw.

[0033] During operation, the DC motor 15 is started, driving the driven gear 14 located in the middle to rotate. Since the driven gear 14 is meshed, its rotation drives the gears on both sides to rotate synchronously. At this time, the distance between the sliding rods can be manually adjusted to accommodate screws of different sizes. When the screw is stuck in the middle of the limiting rod 112, the disinfectant in the middle of the storage box 12 can flow through the hose 13 to the middle of the rotating shaft 113. A small hole is opened in the middle of the rotating shaft 113, allowing the disinfectant to wet the brush 19 and clean the screw. After cleaning, the distance between the limiting rods 112 is adjusted so that the screw passes through the bottom of the disinfection box body 11. The feed inlet 17 drops to the middle of the disinfection chamber body 1 for subsequent operations. Screws are placed inside the disinfection chamber body 1, at which point the screws are in contact with the placement component. After the screws are placed, the vibration motor 26 is started, causing the filter plate 2 to vibrate inside the disinfection chamber body 1. As the filter plate 2 vibrates, the screws placed on top of it vibrate synchronously, shaking off the disinfectant solution adsorbed on its surface. The falling disinfectant solution passes through the filter holes on the surface of the filter plate 2. The waste disinfectant solution drips to the bottom of the disinfection chamber body 1. With the continuous operation of the vibration motor 26, the surface of the screws is shaken off. The disinfectant solution adsorbed on the surface is continuously vibrated and drips off. Because the base plate 31 is hinged, when the screw falls to the middle of the placement box 3, the buckle 32 can be pushed to the middle of the slot, so that the base plate 31 is tightly connected to the placement box 3. When the screw needs to be stored separately, the base plate 31 can be opened to pour out the screw. After the screw is disinfected, the used disinfectant solution will flow through the filter holes in the middle of the filter plate 2 to the top of the guide plate 4. Because the guide plate 4 is inclined, the disinfectant solution will flow along the inclined surface. The chute in the middle of the guide plate 4 further guides the flow of the disinfectant solution, so that it can flow more concentratedly and orderly in a specific direction, and finally pass through the chute. The filter plate 2 at the end is discharged into the externally connected drain pipe 41 and then discharged from the drain pipe 41. By placing screws of different specifications into different second sleeves 5, the screws are classified and managed. The size, shape and internal structure of the collection box 51 can be customized according to the characteristics of screws of different specifications in order to better accommodate and fix the screws and prevent them from colliding, squeezing or tangling with each other during storage. The partition 6 can divide the space inside the disinfection box body 1 into multiple areas in the horizontal direction. Each area corresponds to the placement of screw collection boxes 51 of different specifications. The nylon placement box 3 has good flexibility and elasticity.
