[0002] Currently, in the treatment of bone defects, autologous bone, allogeneic bone and synthetic bone substitute materials are commonly used bone defect repair materials. Bone defect repair materials usually need to be treated with certain physical and chemical methods before being put into use to reduce or avoid the occurrence of rejection by eliminating antigenicity. For bone repair materials, the aforementioned physical and chemical treatments usually include deproteinization and washing. Deproteinization and washing refers to the removal of proteins on bone repair materials through a washing process. The antigenicity of deproteinized bone repair materials is reduced or eliminated.

[0003] The existing deproteinization cleaning device has the following problems: first, the existing cleaning device cannot apply sufficient disturbance to the bone repair material, which reduces the efficiency and effect of deproteinization cleaning; second, the existing cleaning device usually adopts a spray cleaning method, because the bone repair material cannot maintain sufficient contact with the cleaning liquid, resulting in unsatisfactory efficiency and effect of deproteinization cleaning. In summary, it is necessary to develop and design a new deproteinization cleaning device to solve the above technical problems. Utility Model Content

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0022] See also Figure 1The bone repair material deproteinization and cleaning device of the utility model comprises a cabinet 3, in which a cleaning bucket 8 is supported and installed by a support seat 13, a lifting frame 6 is provided above the cleaning bucket 8, a support rod 5 is installed below the lifting frame 6, and a detachable cleaning basket 10 is installed at the lower part of the support rod 5. A lifting driving component is also installed in the cabinet 3 to drive the lifting frame 6 to move up and down, so that the cleaning basket 10 is immersed downward in the cleaning liquid (such as hydrogen peroxide solution) in the cleaning bucket 8 or detached upward.

[0023] The bone repair material to be cleaned is placed in the cleaning basket 10, which is open at the top and has holes on the bottom wall and side walls, and the cleaning liquid is injected into the cleaning bucket 8. The lifting drive assembly drives the lifting frame 6 to move up and down, so that the cleaning basket 10 rises or falls. When the cleaning basket 10 falls to the lower position, the cleaning basket 10 and the bone repair material inside it are immersed in the cleaning liquid, producing a soaking effect.

[0024] In this embodiment, the lifting drive assembly is two left and right lifting cylinders 2 installed in the cabinet. The upper ends of the piston rods of the lifting cylinders 2 are fixedly connected to the lifting frame 6. When the piston rods of the two lifting cylinders 2 move synchronously, the lifting frame 6 rises or falls, and the cleaning basket 10 is lifted or lowered accordingly.

[0025] In this embodiment, the cleaning basket 10 is suspended and supported by the left and right support rods 5, and a clamp 9 is installed between the lower ends of the two support rods 5. The top edge of the cleaning basket 10 is clamped and fixed by the clamp 9. In this way, the cleaning basket 10 can be loaded or removed conveniently, which is convenient for placing bone repair materials into the cleaning basket 10 or taking them out of the cleaning basket 10.

[0026] A flow stirring assembly is installed in the cleaning basket 10, and the flow stirring assembly is used to promote the flow of the cleaning liquid in the cleaning barrel 8, and promote the partial dissociation of protein and bone by applying a disturbance to the cleaning liquid and the bone repair material. In this embodiment, the flow stirring assembly includes a shaft seat 16 installed in the middle of the bottom wall of the cleaning barrel 8, a rotating shaft and a rotary seal are installed in the shaft seat 16, a U-shaped flow stirring impeller 11 is installed at the upper end of the rotating shaft, and also includes a flow stirring motor 12 located below the cleaning barrel 8, and pulleys are installed on the output shaft and the rotating shaft of the flow stirring motor 12, and the two pulleys are connected by belts.

[0027] When the cleaning basket 10 is lowered to a low position, it is located in the inner space of the stirring impeller 11 , and the stirring motor 12 drives the stirring impeller 11 to rotate, so that the cleaning liquid in the cleaning barrel 8 flows along the stirring direction of the stirring impeller 11 .

[0028] A cleaning brush assembly 7 driven by a lifting mechanism 4 is also installed in the cabinet 3. The lifting mechanism 4 drives the cleaning brush assembly 7 to descend to the inside of the cleaning basket 10. During the cleaning process, the cleaning brush assembly 7 acts on the bone repair material inside the cleaning basket 10, which can promote the dissociation of protein and bone.

[0029] See also Figure 2 , we can see that:

[0030] The cleaning brush assembly 7 includes a center seat 7-6, a brush motor 7-1 is installed above the center seat 7-6, and a driving gear 7-8 is installed on the output shaft of the brush motor 7-1. A plurality of arms 7-4 are installed around the center seat 7-6. In this embodiment, the arms 7-4 are arranged to be four and extend in radial directions. A coaxial driven gear 7-9 and a driving pulley 7-2 are installed at the inner end of each arm 7-4, and a coaxial driven pulley 7-3 and a brush roller 7-7 are installed at the outer end of each arm 7-4. Each driven gear 7-9 is meshed with the driving gear 7-8 for transmission, and the driving pulley 7-2 and the driven pulley 7-3 are connected by a transmission belt 7-5.

[0031] The brush motor 7-1 drives the driving gear 7-8 to rotate, and the driving gear 7-8 drives each driven gear 7-9 to rotate synchronously, and the transmission belt 7-5 transmits the above-mentioned rotation to the brush roller 7-7, so each brush roller 7-7 rotates synchronously. The brush roller 7-7 includes a roller body located in the center, and flexible bristles are arranged on the outer wall of the roller body.

[0032] The lifting mechanism 4 includes a mounting plate 4-3 fixedly connected to the cabinet 3, a base 4-4 and a lifting drive motor 4-1 are mounted on the mounting plate 4-3, a lifting longitudinal beam 4-7 is arranged on the side of the base 4-4, a rack 4-6 and a track 4-5 are mounted on the lifting longitudinal beam 4-7, a track block on the track 4-5 is fixedly connected to the base 4-4, and a gear mounted on the output shaft of the lifting drive motor 4-1 is meshed with the rack 4-6 for transmission. The lifting drive motor 4-1 drives the gear to rotate, and due to the cooperation between the gear and the rack 4-6, the rack 4-6 drives the lifting longitudinal beam 4-7 to move up and down, and the cooperation between the track block and the track 4-5 can improve the stability of the lifting longitudinal beam 4-7 when it moves up and down.

[0033] A lifting base plate 4-2 is installed at the lower end of the lifting longitudinal beam 4-7, and a brush motor 7-1 and a center seat 7-6 of the cleaning brush assembly 7 are installed on the lifting base plate 4-2.

[0034] A circulating filter assembly connected to the cleaning barrel 8 is also installed in the cabinet 3. The circulating filter assembly is used to circulate and filter the cleaning liquid in the cleaning barrel 8, timely and effectively filter out foreign particles in the cleaning liquid, and prevent the foreign particles from being adsorbed on the bone repair material again.

[0035] Please join the Figure 3 , we can see that:

[0036] The circulation filtration assembly includes a water pump 17 and a filter 18. The inlet of the water pump 17 is connected to the outlet of the filter 18. The outlet of the water pump 17 is connected to the bottom of the side wall of the washing bucket 8 through a pipeline. The inlet of the filter 18 is connected to the middle of the side wall of the washing bucket through a pipeline. During operation, under the action of the water pump 17, the upper layer of the cleaning liquid is pumped out of the washing bucket 8. When passing through the filter 18, the impurity particles contained are trapped. The filtered cleaning liquid passes through the water pump 17 and is injected into the bottom of the inner cavity of the washing bucket 8, thus forming a filtration cycle.

[0037] In this embodiment, Figure 1 As shown in the figure, two cleaning barrels 8 are arranged side by side on the left and right, and correspondingly, two cleaning baskets 10 are arranged on the left and right, and two groups of support rods 5 are arranged on the left and right. Correspondingly, the lifting mechanism 4, the cleaning brush assembly 7 and the circulating filter assembly are arranged on the left and right, and the stirring assembly of the two cleaning barrels 8 shares the same stirring motor 12.

[0038] like Figure 1 As shown in , rollers 14 and telescopic support legs 15 are installed at the four corners of the bottom of the cabinet 3. When shifting is required, the telescopic support legs 15 are operated to retract. After being pushed to the appropriate position, the telescopic support legs 15 are operated to extend until the lower end is against the ground, which can improve the overall stability. A control box 1 is also installed on the outside of the cabinet 3. The control box 1 is provided with operating buttons, including a button for controlling the synchronous action of the two lifting cylinders 2 (controlling the solenoid valve to realize the lifting cylinder 2), a button for controlling the start and stop of the stirring motor 12, a button for controlling the forward or reverse rotation of the lifting drive motor 4-1, a button for controlling the start and stop of the brush motor 7-1, and a button for controlling the start and stop of the two water pumps 17.

[0039] Directions:
