Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode technology, and more specifically, to a bone cement mixing device. Background Technology
[0002] Bone cement mixing devices are widely used in orthopedic surgeries. Current technology largely relies on manual mixing, typically using a bowl and rod. Manual operation easily leads to poor mixing uniformity, introduces air bubbles, reduces the mechanical strength of the bone cement, and consequently affects surgical outcomes. Furthermore, the prolonged mixing process causes the temperature of the mixed bone cement to rise, which in turn reduces the surgeon's operating time and increases clinical workload.
[0003] Existing bone cement mixing devices are often used as consumables because the mixed bone cement is difficult to clean. Therefore, the cost of these devices needs to be considered. Current devices typically mix bone cement by hand-shaking and then discharge it using a pump. Because they lack a cooling function, the injected bone cement material is often cooled before being injected into the mixing device. Since the hand is in contact with the mixing device, the hand's heat is transferred to the mixing device and then to the mixed bone cement, causing the bone cement inside the mixing device to heat up, thus shortening the operator's operation time. To address the cost and temperature rise issues, a radiofrequency plasma ablation electrode with negative pressure adsorption is proposed. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0024] Reference Figures 1-7This utility model provides an embodiment of a bone cement mixing device, comprising a mixing component 1, a heat insulation component 2 installed on the upper end of the mixing component 1, and a heat-conducting component 3 disposed inside the heat insulation component 2. The mixing component 1 has a tubular structure with one end closed, and the other end of the mixing component 1 is installed on the heat insulation component 2. The heat-conducting component 3 and the internal space of the mixing component 1 are interconnected. Therefore, after installation, the mixing component 1 and the heat-conducting component 3 are used to mix the bone cement stored inside. A third storage chamber 20 for storing a cooling medium is provided between the heat insulation component 2 and the heat-conducting component 3. The heat-conducting component 3 is used to discharge the mixed bone cement. The cooling medium in the third storage chamber 20 acts on the bone cement to be discharged through the heat-conducting component 3, so that the temperature of the bone cement to be discharged is controlled within the range of 5℃-20℃. Since the curing speed of bone cement increases with increasing temperature, the external temperature during the mixing process can cause the bone cement temperature to rise, which would reduce the operation time. Therefore, this bone cement mixing device provides the operator with sufficient operation time. In this embodiment, the internal bone cement can be mixed by hand-shaking the stirring component 1, thus giving the stirring component 1 a stirring function; wherein the heat-conducting component 3 is used to discharge the mixed bone cement.
[0025] In this application, it was discovered that a 1°C increase in temperature of the stirred bone cement shortens the operation time by 1-3 minutes. Therefore, it is necessary to cool the stirred bone cement. Existing mixing devices typically mix bone cement by hand-shaking and then discharge it under the suction of a dispensing device. Because existing bone cement mixing devices lack a cooling function, they often cool the injected bone cement material before mixing. Since the hand is in contact with the mixing device, the hand's heat acts on the device and is transferred to the mixed bone cement, causing the bone cement inside the mixing device to heat up, thus shortening the operator's operation time. In this application, the temperature of the heat-conducting component 3 is 5°C-20°C. By providing a third storage cavity 20 between the heat insulation component 2 and the heat-conducting component 3, the heat-conducting component 3 can cool the bone cement to be discharged. Simultaneously, the bone cement in contact with the heat-conducting component 3 is cooled during the shaking of the bone cement mixing device. Therefore, even when the hand is holding the mixing component 1, the bone cement to be discharged can still be cooled through the heat-conducting component 3. In this application, the heat-conducting component 3 and the heat-insulating component 2 are respectively the inner and outer layers of the end cap. A third storage cavity 20 is provided between the heat-conducting component 3 and the heat-insulating component 2. Cooling medium is injected into the third storage cavity 20, and the heat-conducting component 3 and the heat-insulating component 2 are refrigerated before use, thus ensuring the cooling effect on the bone cement. The refrigeration temperature is between 5℃ and 20℃. In this embodiment, the heat-insulating component 2 and the heat-conducting component 3 are integrally formed or detachably connected. When the heat-insulating component 2 and the heat-conducting component 3 are integrally formed, they are made of the same material. When the heat-insulating component 2 and the heat-conducting component 3 are detachably connected, it is not limited whether the materials of the heat-insulating component 2 and the heat-conducting component 3 are the same. This embodiment achieves cooling treatment of the bone cement mixing device with a low-cost structural design.
[0026] As a further improved embodiment, the heat insulation component 2 and the heat conduction component 3 are detachably connected. A preferred connection method is a threaded connection between the heat insulation component 2 and the heat conduction component 3. A third storage cavity 20 is provided between the heat insulation component 2 and the heat conduction component 3, and the third storage cavity 20 is sealed and constructed by installing the heat conduction component 3. The heat insulation component 2 includes a first tubular connecting part 21 mounted on the stirring component 1, a first conical connecting part 22 located above the first tubular connecting part 21, and a second tubular connecting part 23 located above the first conical connecting part 22. That is, the heat insulation component 2 includes the first tubular connecting part 21, the first conical connecting part 22, and the second tubular connecting part 23 connected sequentially from bottom to top. A preferred embodiment is that the first tubular connecting part 21, the first conical connecting part 22, and the second tubular connecting part 23 are an integral structure.
[0027] The heat-conducting component 3 includes a third tubular connecting part 31 at the lower end, a second conical connecting part 32 at the upper end of the third tubular connecting part 31, and a push-in tube connector 33 above the second conical connecting part 32. That is, the heat-conducting component 3 includes the third tubular connecting part 31, the second conical connecting part 32, and the push-in tube connector 33 connected sequentially from bottom to top. The third tubular connecting part 31, the second conical connecting part 32, and the push-in tube connector 33 are an integral structure. The outer diameter of the push-in tube connector 33 is adapted to the inner diameter of the second tubular connecting part 23. The push-in tube connector 33 is inserted into the second tubular connecting part 23. The third tubular connecting part 31 is used to seal the bottom end of the third storage cavity 20, and the push-in tube connector 33 is used to seal the top end of the third storage cavity 20.
[0028] In this application, the axial cross-sections of the second tapered connecting portion 32 and the first tapered connecting portion 22 are curved or straight. In this application, the heat insulation component 2 and the heat conduction component 3 are detachable via a threaded connection, facilitating the replacement of the cooling medium in the third storage chamber 20. The cooling medium is either coolant or air.
[0029] As a further improved embodiment, a fifth protrusion 312 is provided on the curved surface of the lower end of the third tubular connecting part 31, and the fifth protrusion 312 is fixed in the first tubular connecting part 21 by providing an external thread on the curved surface; in this embodiment, the fifth protrusion 312 and the third tubular connecting part 31 are integrally connected.
[0030] The inner wall of the first tubular connecting part 21 is provided with a second protrusion 212 in an annular structure. The second protrusion 212 is used to restrict the axial displacement of the fifth protrusion 312, and the fifth protrusion 312 abuts against the second protrusion 212 to seal the lower end of the third storage cavity 20, thereby preventing the cooling medium from leaking between the fifth protrusion 312 and the second protrusion 212.
[0031] A sealing ring 5 is installed at the upper end of the second tubular connecting part 23;
[0032] The upper end of the injection tube connector 33 is provided with a sixth protrusion 331 in the form of a tubular structure. The outer diameter of the sixth protrusion 331 is smaller than the outer diameter of the injection tube connector 33. Therefore, an annular gap is provided between the injection tube connector 33 and the second tubular connection part 23. The axial section of the sealing ring 5 is trapezoidal. The lower end of the sealing ring 5 is screwed into the space between the injection tube connector 33 and the second tubular connection part 23. Therefore, the sealing ring 5 achieves sealing of the upper end of the third storage cavity 20.
[0033] As a further improved embodiment, a third protrusion 231 is also provided on the curved surface of the upper end of the second tubular connecting part 23, the third protrusion 231 being used to install the bone cement extraction component or the third sealing cap.
[0034] As a further improved embodiment, the fifth protrusion 312 is provided with a first injection hole 3120, which is used to inject cooling medium into the third storage cavity 20. In this embodiment, the cooling medium is coolant.
[0035] In this application, a second sealing cap is installed in the first injection hole 3120 to seal the first injection hole 3120. The sealing ring 5 is removed to facilitate the injection or discharge of cooling medium into the third storage cavity 20. Subsequently, the third storage cavity 20 is sealed by installing the second sealing cap and the sealing ring 5 respectively. The fifth protrusion 312 in this application has a trapezoidal axial cross-section, allowing it to abut against the second protrusion 212 via a threaded connection.
[0036] As a further improved embodiment, the injection tube connector 33 is provided with a first delivery channel 301 and a second delivery channel 302 from bottom to top; the first delivery channel 301 and the second delivery channel 302 are interconnected; wherein the axial section of the second delivery channel 302 is straight or conical, and the shape of the axial section of the first delivery channel 301 is not limited.
[0037] As a further improved embodiment, the outer surface of the first tubular connecting part 21 is provided with a plurality of first protrusions 211. By providing the first protrusions 211, it is easy to rotate and fix it on the stirring assembly 1, and avoids hand contact with the first tubular connecting part 21, thereby avoiding the hand temperature from affecting the temperature of the cooling medium in the third storage chamber 20.
[0038] As a further improved embodiment, the third tubular connecting portion 31 is provided with a plurality of first grooves 310, which are arranged in a circumferential array on the third tubular connecting portion 311. A fourth protrusion 311 is provided between adjacent first grooves 310, and the fourth protrusion 311 can serve as a heat dissipation fin on the third tubular connecting portion 31. In this embodiment, by providing a plurality of first grooves 310 on the third tubular connecting portion 31, the wall thickness of the third tubular connecting portion is reduced, and the cooling effect of the third tubular connecting portion 311 on the mixed bone cement is further improved under the action of the fourth protrusion 311.
[0039] In a preferred embodiment, the heat-conducting component 3 is made of metal, and the heat-insulating component 2 is made of plastic. This embodiment does not limit the material of the heat-conducting component 3 in the above embodiments; it is merely a preferred implementation method in this embodiment.
[0040] As a further improved embodiment, the stirring assembly 1 has a tubular structure, and a first storage tube 11 is also provided inside the stirring assembly 1. The first storage tube 11 and the stirring assembly 1 are integrally connected or detachably connected.
[0041] A first storage chamber 10 is provided between the first storage tube 11 and the stirring assembly 1, and a second storage chamber 110 is provided in the first storage tube 11;
[0042] The second storage cavity 110 is used to hold bone cement;
[0043] The heat-conducting component 3 is provided with a fourth storage cavity 30, which is connected to the second storage cavity 110 to facilitate the flow of bone cement from the second storage cavity 110 to the fourth storage cavity 30. The first storage cavity 10 in this application is used to inject coolant to give the stirring component 1 a cooling function; wherein the wall thickness of the stirring component is not less than the wall thickness of the first storage tube 11.
[0044] As a further improved embodiment, the lower end of the first storage tube 11 is connected to a centrifuge tube 111, which has a conical structure to ensure thorough mixing of the bone cement. In this embodiment, the first storage tube 11 is used to stir the internal bone cement mixture by manually shaking the stirring assembly 1. The centrifuge tube 111 at the bottom of the first storage tube 11 ensures that the mixed bone cement is stirred evenly.
[0045] As a further improved embodiment, a first sealing cap 4 is installed at the lower end of the stirring assembly 1. The first sealing cap 4 facilitates the discharge or injection of coolant into the first storage chamber 10. In this embodiment, the first sealing cap 4 is not limited to having a diameter matching the inner diameter of the stirring assembly 1; rather, the diameter of the first sealing cap 4 is smaller than the inner diameter of the stirring assembly 1. The lower end of the stirring assembly 1 has a closed structure, and a liquid inlet is provided at the lower end of the stirring assembly 1 to allow the coolant to be injected into or discharged from the first storage chamber 10. The first sealing cap 4 is used to seal the liquid inlet on the stirring assembly 1. In this embodiment, the stirring assembly 1 has a cooling function by providing a first storage chamber 10 within it. Before use, the stirring assembly 1 is refrigerated to effectively prevent hand temperature from affecting the temperature of the mixed bone cement inside due to handling the stirring assembly 1.
[0046] As a further improved embodiment, the fifth protrusion 312 and the first storage tube 11 abut against each other. Since the fifth protrusion 312 and the third tubular connecting part 31 are integrally connected, the inner diameter of the third tubular connecting part 31 is the same as the inner diameter of the first storage tube 11. This avoids the accumulation of mixed bone cement in the bone cement mixing device.
