Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly relates to a blending device for bone repair materials. Background Art

[0002] Bone repair materials refer to a special type of materials used for treating and promoting the healing of fractures, bone defects, or other bone-related diseases. When preparing bone repair materials, different raw materials need to be mixed. However, due to problems with the mixing process or equipment, the materials may not be mixed evenly, resulting in inconsistent mechanical properties of the materials, such as strength and toughness. Uneven mixing may cause uneven distribution of certain components in the materials, thereby triggering an immune response.

[0003] In the prior art, timely mixing of bone repair materials can ensure the full fusion of various components during the preparation process, thereby improving the uniformity and consistency of the materials. It can also reduce the time for the materials to come into contact with the external environment during preparation and storage, thereby reducing the risk of contamination. However, since the mixing process needs to be completed in a short time, uneven mixing may occur due to insufficient mixing time. Therefore, the present invention provides a blending device for bone repair materials with good mixing effect, which is convenient for dissolving different materials and ensures uniform mixing.

An accommodating chamber for pre-storing materials is provided between adjacent stirring blades;

[0006] A driving member is fixedly connected to the outer wall of the stirring chamber. The output shaft of the driving member is coaxially and fixedly connected with a lead screw.

[0014] The driving shaft is detachably connected to the mixing chamber, and the driving shaft is in sliding fit with the stirring blade.

[0015] Furthermore, a number of grasping teeth are fixedly connected to the stirring blade.

[0016] Furthermore, a top block is provided between adjacent stirring blades.

[0017] Furthermore, a funnel-shaped transfer groove is formed on one side of the mixing chamber away from the liquid inlet pipe, and the transfer groove is communicated with the conveying pipe.

[0041] The following is a further detailed description through specific implementation manners:

[0042] Embodiment 1:

[0043] As shown in the Figures 1 to 10 accompanying drawings: A bone repair material blending device includes a stirring chamber 1. The stirring chamber 1 includes a first clamping plate 11 and a second clamping plate 12, and the first clamping plate 11 and the second clamping plate 12 are threadedly connected.

[0044] Inside the stirring chamber 1, there is a stirring mechanism for dissolving and stirring different materials. The stirring mechanism includes a driving shaft 14. A number of stirring blades 4 are provided on the driving shaft 14. An accommodating chamber for pre-storing materials is provided between adjacent stirring blades 4. The stirring mechanism also includes a driving member fixedly connected to the outer wall of the stirring chamber 1 by screws. In this embodiment, the driving member is a motor 2. The output shaft of the driving member is coaxially clamped with a lead screw 21. A nut seat 22 is slidably fitted on the lead screw 21. A connecting rod 24 is rotatably fitted on the nut seat 22. The connecting rod 24 is circumferentially arranged around the lead screw 21. A first turntable 23 is also slidably fitted on the lead screw 21. The first turntable 23 is welded to the connecting rod 24. The stirring blades 4 are semi-spherical. A second turntable 41 is integrally formed at the center of each stirring blade 4. The second turntable 41 is rotatably fitted with the driving shaft 14. Both ends of the driving shaft 14 are threadedly connected to the stirring chamber 1. The driving shaft 14 is slidably fitted with the stirring blades 4. An annular groove 5 is formed on the second turntable 41. A clamping piece 51 is provided in the annular groove 5. One end of the clamping piece 51 is rotatably fitted with the second turntable 41, and the other end of the clamping piece 51 is located in the annular groove 5.

[0045] When the connecting rod 24 moves inside the second turntable 41, the connecting rod 24 is located in the annular groove 5. When the connecting rod 24 rotates clockwise, the connecting rod 24 abuts against the clamping piece 51. When the connecting rod 24 rotates counterclockwise, the connecting rod 24 is slidably fitted with the clamping piece 51.

[0046] A number of branch pipes 42 are communicated inside the stirring blade 4. A number of liquid outlet holes 43 are formed on each stirring blade 4. The liquid outlet holes 43 are communicated with the branch pipes 42. One end of the branch pipe 42 far from the liquid outlet hole 43 is located inside the driving shaft 14, and one end of the branch pipe 42 far from the liquid outlet hole 43 is communicated with the outside.

[0047] A liquid inlet pipe 13 for adding solution is communicated with the top of the stirring chamber 1. A conveying pipe 3 for outputting the stirred and mixed materials is communicated with the bottom of the stirring chamber 1. A funnel-shaped transfer groove is formed on one side of the stirring chamber 1 far from the liquid inlet pipe 13. The transfer groove is communicated with the conveying pipe 3. The liquid inlet pipe 13 and the conveying pipe 3 are on the same vertical line. A turning mechanism for automatically stirring materials is provided inside the conveying pipe 3. In this embodiment, the turning mechanism is a fan blade rotatably fitted with the conveying pipe 3 to stir and mix the slurry inside the conveying pipe 3.

[0048] In another embodiment, the turning mechanism includes an arc-shaped moving plate 31. A mounting frame 32 is fixedly connected to the center of the conveying pipe 3. The mounting frame 32 is rotatably fitted with one end of the moving plate 31. The other end of the moving plate 31 is fixedly connected with a slider 33. The slider 33 is slidably fitted with the conveying pipe 3.

[0049] The specific implementation process is as follows:

[0050] First, the physician installs the materials layer by layer between adjacent stirring plates. By pre-storing different materials, the ratio calculation of temporary mixing is reduced, improving work efficiency. At the same time, due to the isolation of the multi-layer stirring blades 4, the materials in the accommodating chamber are gradually infiltrated according to the distribution situation, reducing the occurrence of undissolved materials, so that different stratified materials are fully dissolved and mixed during the stirring process, improving the mixing efficiency.

[0051] And due to the detachable stirring chamber 1 formed by the first clamping plate 11 and the second clamping plate 12, it is convenient to disassemble and clean the device after use. At the same time, using the separated stirring chamber 1, it is convenient to disassemble the stirring blades 4 on the driving shaft 14. So during the installation process of the stirring blades 4, materials can be stacked between different stirring blades 4, and then the stirring blades 4 are used to press the stacked materials to form an accommodating chamber between adjacent stirring blades 4, thus pre-saving the materials, facilitating the loading of drugs, and improving work efficiency.

[0052] During the stirring process, the motor 2 is started to drive the lead screw 21 to rotate. The lead screw 21 drives the nut seat 22 to move along the lead screw 21, continuously pushing the connecting rod 24 to move. At the same time, the lead screw 21 drives the connecting rod 24 to rotate on the nut seat 22 through the first turntable 23. When the connecting rod 24 is inserted into the annular groove 5 on the second turntable 41, using the clamping effect between the connecting rod 24 and the clamping piece 51, the stirring blades 4 fixedly connected to the second turntable 41 are continuously pushed to rotate, so that the stirring blades 4 at different heights rotate in sequence in the stirring chamber 1, forming a multi-time stirring effect, facilitating the solvent mixing and dissolution of different materials in the stirring chamber 1.

[0053] At the same time, through the setting of the liquid outlet hole 43, the solution is injected in advance through the branch pipe 42 to infiltrate the materials between the stirring blades 4, performing an infiltration treatment on the materials between the stirring blades 4, reducing the influence of the surface tension of water molecules on the materials during the contact between the materials and water, preventing the materials from being wrapped and forming agglomerated substances that are not easily dissolved, facilitating the materials to dissolve in the solution during the stirring and mixing process, and improving the dissolution efficiency.

[0054] After the mixing is completed, the physician rotates the orientation of the stirring chamber 1, and uses the indication of the liquid inlet pipe 13 to confirm the position of the delivery pipe 3, so that the materials inside the stirring chamber 1 naturally fall into the delivery pipe 3 due to gravity. Then, through the funnel-shaped transfer groove, it is convenient for the materials inside the stirring chamber 1 to enter the delivery pipe 3, facilitating the outflow of the stirred and mixed materials inside the stirring chamber 1. Finally, the slurry inside the delivery pipe 3 is used to drive the moving plate 31 to rotate inside the delivery pipe 3, and the moving plate 31 rotates to mix the slurry inside the delivery pipe 3, reducing the sedimentation phenomenon of the slurry inside the delivery pipe 3.

[0055] Example 2:

[0056] The difference from Example 1 is that a number of grasping teeth 44 are welded on the stirring blade 4.

[0057] The specific implementation process is as follows: During the process of the stirring blade 4 rotating layer by layer, the material layer inside the accommodation chamber is scraped by the grasping teeth 44 to form a gradual dissolution. At the same time, during the movement of the grasping teeth 44 in the stirring chamber 1, the bubbles generated during the stirring process are punctured to facilitate the full mixing of the material inside the accommodation chamber with the solution.

[0058] Example 3:

[0059] The difference from Example 2 is that a top block (not shown in the figure) is provided between adjacent stirring blades 4, and the top block is fixedly connected to the stirring blade.

[0060] The specific implementation process is as follows: During the process of adding materials, the adjacent stirring blades 4 are supported by the top block to control the distance between adjacent stirring blades 4 to form an accommodation chamber, ensuring that the materials stacked inside the accommodation chamber are in a moderate pressing state to facilitate the dissolution of the materials during the subsequent mixing process.

[0061] Example 4:

[0062] The difference from Example 3 is that an elliptical detection chamber is communicated with one side of the conveying pipe 3 close to the moving plate 31. A pressure sensor is provided between the detection chamber and the moving plate 31, and the pressure sensor is electrically connected to a control panel (not shown in the figure); the pressure sensor is used to measure the real-time pressure value applied by the moving plate 31 to the inner wall of the detection chamber and send the real-time pressure value to the control panel;

[0063] The control panel is electrically connected to a display panel (not shown in the figure). The control panel is used to draw a waveform diagram based on the real-time pressure value and send the waveform diagram to the display panel for display.

[0064] For example, the real-time pressure value applied by the moving plate 31 to the inside of the detection chamber is confirmed by using the pressure sensor to determine the type of slurry in the gap between the moving plate 31 and the conveying pipe 3. Under normal circumstances, after the materials are mixed, they have a certain viscosity and support strength. Therefore, during the process of the moving plate 31 extruding the slurry, the slurry inside the current conveying pipe 3 will form a support and exert pressure on the pressure sensor.

[0065] If the slurry is thinner, the support strength of the slurry is lower, and the real-time pressure value collected by the pressure sensor decreases accordingly; if the slurry is more viscous, the support strength of the slurry is greater, and the real-time pressure value collected by the pressure sensor increases accordingly, so as to test the mixing effect of the materials. During the process of mixing the materials, based on the uniformly mixed materials, the real-time pressure value received by the pressure sensor should fluctuate within a certain range. The doctor judges whether the current mixing uniformity of the materials meets the standard based on the waveform diagram.

[0066] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
