At present, when using the root canal file for root canal treatment, the root canal preparation machine is used as the power source to drive the root canal file to rotate.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the prior art, after the root canal file is processed, its root rigidity is insufficient, and when used, it will shake, thus affecting the treatment effect. Secondly, the blade of the root canal file is not flexible enough, and it cannot be pre-bent when dealing with curved and complex root canals, or cannot adapt to its anatomical structure well in curved and complex root canals to straighten the root canals; in addition, the end of the existing root canal file is a sharp tip, which is not very guiding and is prone to complications such as steps and side penetration.

[0040] In view of this, the designer provides a root canal file processing equipment. The root canal files processed by the equipment are of high quality, with high root rigidity and not easy to shake during use; the blade is flexible and adaptable; the end has good guidance and is not prone to complications.

[0041] Please combine Figure 1 and Figure 2 In the present embodiment, it should be noted that the root canal file processing device is used for processing a root canal file body 001, and the root canal file body 001 includes a handle portion 011, a rod portion 012, and a file blade portion 013 which are connected in sequence, wherein the handle portion 011 and the rod portion 012 are detachably connected, the rod portion 012 and the file blade portion 013 can be made of the same material, for example, the rod portion 012 and the file blade portion 013 can be made of nickel-titanium alloy, and the file blade portion 013 includes a first rod segment 0131 and a second rod segment 0132 both of which are spiral structures, the length of the first rod segment 0131 is greater than the length of the second rod segment 0132, the two ends of the first rod segment 0131 are respectively connected to the rod portion 012 and the second rod segment 0132, and the end of the second rod segment 0132 away from the first rod segment 0131 is the distal end of the root canal file body 001, that is, the end extending into the oral cavity. The end of the second rod segment 0132 away from the first rod segment 0131 is set to be an arc surface, that is, a blunt surface, without a chip cutting edge, which enhances the guiding performance and is not easy to form complications such as steps and side penetration during use. Among them, the hardness component of the rod 012, the second rod segment 0132 and the first rod segment 0131 is reduced, that is, the hardness of the rod 012 is the largest, and the hardness of the second rod segment 0132 is the smallest.

[0042] Please combine Figure 2 In this embodiment, the root canal file processing device includes a first processing module 100, a second processing module 200 and a third processing module 300 connected in sequence. At least one of the first processing module 100, the second processing module 200 and the third processing module 300 is provided with a positioning portion for positioning the root canal file body 001, the first processing module 100 is used to heat or cool the rod portion 012, the second processing module 200 is used to heat or cool the first rod segment 0131, and the second processing module 200 is used to heat or cool the second rod segment 0132.

[0043] Based on the above scheme, the working mode of the root canal file processing device provided in this embodiment is as follows:

[0044] According to the processing requirements, the stem 012, the first stem segment 0131 and the second stem segment 0132 of the root canal file body 001 are heated in sequence, and when one of the three is heated, the other two can be cooled to ensure that the heat at the heated position does not easily affect the unheated position, thereby improving the quality of the heat treatment of the root canal file body 001. The obtained stem 012 of the root canal file body 001 has high hardness and less shaking when used; and the first stem segment 0131 of the root canal file body 001 has good flexibility, good passability, strong adaptability, and is more flexible when operated. During processing, the end of the second stem segment 0132 is set to an arc surface, that is, a blunt surface, without a chip cutting edge, to enhance guidance, and not easily form complications such as steps and side penetration during use.

[0045] For example, in one embodiment, the rod portion 012 may be heated first, then the first rod segment 0131 may be heated, and finally the second rod segment 0132 may be heated. Alternatively, in other embodiments, the rod portion 012 may be heated first, then the second rod segment 0132 may be heated, and then the first rod segment 0131 may be heated. Alternatively, other sequences may be used to sequentially heat different positions of the root canal file body 001. In this embodiment, the heating sequence of the rod portion 012, the first rod segment 0131, and the second rod segment 0132 is not limited, and the example of first heating the rod portion 012, then heating the second rod segment 0132, and finally heating the first rod segment 0131 is used for explanation.

[0046] It should be understood that when the rod portion 012 is heated, the first rod segment 0131 and the second rod segment 0132 are respectively in a cooling environment. Similarly, when the first rod segment 0131 is heated, the rod portion 012 and the second rod segment 0132 are both in a cooling environment. When the second rod segment 0132 is heated, the rod portion 012 and the first rod segment 0131 are both in a cooling environment.

[0047] In the present embodiment, it should be noted that the first processing module 100 , the second processing module 200 and the third processing module 300 are detachably connected, which is convenient for assembly and disassembly, and also convenient for loading and unloading.

[0048] In one embodiment, the first processing module 100, the second processing module 200 and the third processing module 300 can all be configured to have both heating and cooling functions, that is, when the first processing module 100 needs to be heated, the heating function of the first processing module 100 is activated, and the cooling functions of the second processing module 200 and the third processing module 300 are activated at the same time, and so on. With such a design, the working states of the first processing module 100, the second processing module 200 and the third processing module 300 can be adjusted according to demand, adapting to processing in different scenarios, and having a wide range of uses.

[0049] In another embodiment, optionally, the number of the first processing modules 100 can be two, one of which has a heating function and the other has a cooling function. When it is necessary to use the first processing module 100 to heat the rod 012 of the root canal file body 001, the first processing module 100 with the heating function is selected to be connected to the second processing module 200. Obviously, the number of the second processing modules 200 and the third processing modules 300 can be set to two respectively, one of the two second processing modules 200 has a heating function and the other has a cooling function, and one of the two third processing modules 300 has a heating function and the other has a cooling function. When in use, the first processing module 100, the second processing module 200 and the third processing module 300 with corresponding functions can be selected and combined according to the needs.

[0050] For example, when the rod portion 012 needs to be heated, a first processing module 100 with a heating function, a second processing module 200 with a cooling function, and a third processing module 300 with a cooling function are selected and assembled together, so that the rod portion 012 can be heated while the first rod segment 0131 and the second rod segment 0132 can be cooled independently.

[0051] It should be understood that the heating function of the first processing module 100, the second processing module 200 and the third processing module 300 can be realized by energizing a heating element such as a heating wire, and the cooling function of the first processing module 100, the second processing module 200 and the third processing module 300 can be realized by providing a cooling element and inputting a coolant into the cooling element. Optionally, the heating wire can be extended in a serpentine shape, that is, the heating wire has at least one bend, which can increase the heating area and improve the heating efficiency; the cooling element can be extended in a serpentine shape, that is, the cooling element has at least one bend, which can increase the heat dissipation area and improve the heat dissipation effect.

[0052] It should be understood that in one embodiment, taking the first processing module 100 integrating both heating and cooling functions as an example, the heating element and the cooling element can be arranged crosswise, for example, when the heating element is a spiral structure, the cooling element is also a spiral structure, and a spiral of the cooling element can be arranged between adjacent spirals of the heating element, so that the two are arranged reasonably, and the overall structure is compact, small in size, and easy to use. Obviously, a spacing can be set between adjacent spirals of the heating element and the cooling element.

[0053] In this embodiment, optionally, the first processing module 100 includes a first main body 110 and a first actuator 120, and the first main body 110 is provided with a first positioning hole 111 for positioning the rod portion 012. The first actuator 120 can be set as a heating element or a cooling element. The first actuator 120 is installed on the first main body 110, and the first actuator 120 is used to heat or cool the rod segment.

[0054] It should be understood that the first positioning hole 111 can be a cylindrical groove that matches the shape of the rod 012 to ensure that the rod 012 can be inserted into the first positioning hole 111. The positioning of the root canal file body 001 is achieved through the groove peripheral wall and groove bottom wall of the first positioning hole 111.

[0055] It should be understood that when the first processing module 100 has both heating and cooling functions, there are two first actuators 120, which are a heating element and a cooling element, and both can be installed in the first processing module 100. Alternatively, in other embodiments, when there are two first processing modules 100, each with a heating function and a cooling function, there is one first actuator 120 corresponding to each first processing module 100, one first actuator 120 is a heating element, and the other first actuator 120 is a cooling element.

[0056] Optionally, the second processing module 200 includes a second body 210 and a second actuator 220, the second body 210 is provided with a second positioning hole 211 for positioning the first rod segment 0131, the second actuator 220 is configured as a heating element or a cooling element, the second actuator 220 is mounted on the second body 210, and the second actuator 220 is used to heat or cool the first rod segment 0131. The third processing module 300 includes a third body 310 and a third actuator 320, the third actuator 320 is configured as a heating element or a cooling element, the third body 310 is provided with a third positioning hole 311 for positioning the second rod segment 0132, the third actuator 320 is mounted on the third body 310, and the third actuator 320 is used to heat or cool the second rod segment 0132.

[0057] It should be understood that the second processing module 200 and the third processing module 300 can be configured the same as the first processing module 100, which will not be described in detail in this embodiment, and please refer to the first processing module 100.

[0058] Furthermore, the cooling member may be a cooling pipe.

[0059] In addition, the first processing module 100 and the second processing module 200 can be detachably matched by bolts or buckles, and the second processing module 200 and the third processing module 300 can be detachably matched by bolts or buckles.

[0060] In the present embodiment, it should be noted that the second positioning hole 211 and the third positioning hole 311 can both be conical grooves, the first positioning hole 111 and the third positioning hole 311 are both blind holes, the second positioning hole 211 is a through hole, and the end with a larger diameter of the second positioning hole 211 is connected to the first positioning hole 111 and the diameters of the two are equal, and the end with a smaller diameter of the second positioning hole 211 is connected to the end with a larger diameter of the third positioning hole 311 and the diameters of the two are equal, so that the first positioning hole 111, the second positioning hole 211 and the third positioning hole 311 are smoothly connected. When positioning the root canal file body 001, the second processing module 200 and the third processing module 300 can be assembled first, and then the end of the second rod segment 0132 is inserted into the third positioning hole 311 after passing through the second positioning hole 211, and then the first processing module 100 is assembled, so that the rod portion 012 is inserted into the first positioning hole 111, and the entire device is arranged vertically, with the first processing module 100 located at the top and the third processing module 300 located at the bottom. In this way, relying on the effect of gravity, the root canal file body 001 is positioned in the first positioning hole 111, the second positioning hole 211 and the third positioning hole 311.

[0061] In this embodiment, optionally, the root canal file processing device further includes a heat preservation shell 400, and the first processing module 100, the second processing module 200, and the third processing module 300 are all arranged in the heat preservation shell 400. It should be understood that the heat preservation shell 400 can be a split structure or an integral structure. When the heat preservation shell 400 is a split structure, specifically, the heat preservation shell 400 is a three-section structure, and a section of the heat preservation shell 400 can be arranged on the first body 110, the second body 210, and the third body 310. When the heat preservation shell 400 is an integral structure, after the first body 110, the second body 210, and the third body 310 are assembled, the heat preservation shell 400 is arranged to wrap the first body 110, the second body 210, and the third body 310 at the same time, which can be selected as needed and used flexibly.

[0062] The root canal file processing device provided in this embodiment can heat the rod portion 012, the first rod segment 0131 and the second rod segment 0132 of the root canal file body 001 in sequence according to needs, and during the heating process, cool the corresponding unheated parts, which can improve the heat treatment effect and thus improve the processing quality of the root canal file body 001.

[0063] It should be understood that in other embodiments, when the blank is processed, the austenite phase transformation termination temperature of the rod portion has met the set requirements. Therefore, when the root canal file is processed using the root canal file processing equipment, the first rod segment and the second rod segment are heat treated respectively by two processing modules, namely the second processing module and the third processing module, which can simplify the process, improve efficiency and reduce costs.

[0064] This embodiment also provides a root canal file processing process using a root canal file processing device, the process comprising the following steps:

[0065] When one of the rod 012, the first rod segment 0131, and the second rod segment 0132 is in a heating environment, the other two of the rod 012, the first rod segment 0131, and the second rod segment 0132 are in a cooling environment, so that the heat treatment of the rod 012, the first rod segment 0131, and the second rod segment 0132 is completed in sequence. For example, in this embodiment, the heat treatment is completed in sequence of the rod 012, the second rod segment 0132, and the first rod segment 0131.

[0066] Specifically, the blank is made into the file blade portion 013 with a thread structure by grinding, or grinding and screwing, or electrochemical corrosion, etc. Then, the rod portion 012 and the file blade portion 013 are heat-treated to form austenite.

[0067] During heat treatment, the rod portion 012 is heated at a temperature of 200-400°C by the first processing module 100. At the same time, the first rod segment 0131 and the second rod segment 0132 are cooled respectively by the second processing module 200 and the third processing module 300. The cooling temperature of the second processing module 200 and the third processing module 300 can be set at 5-30°C, which can reduce the influence of the heat generated when heating the rod portion 012 on the first rod segment 0131 and the second rod segment 0132.

[0068] Next, the second rod segment 0132 is heated at a temperature of 250-600°C by the third processing module 300, and the rod portion 012 and the first rod segment 0131 are cooled respectively by the first processing module 100 and the second processing module 200. The cooling temperature of the first processing module 100 and the second processing module 200 can be set at 5-30°C, which can reduce the influence of the heat generated when heating the second rod segment 0132 on the first rod segment 0131 and the rod portion 012.

[0069] Then, the first rod segment 0131 is heated at a temperature of 300-800°C by the second processing module 200, and the rod portion 012 and the second rod segment 0132 are cooled by the first processing module 100 and the third processing module 300 respectively. The cooling temperature of the first processing module 100 and the third processing module 300 can be set at 5-30°C, which can reduce the influence of the heat generated when heating the first rod segment 0131 on the second rod segment 0132 and the rod portion 012.

[0070] Furthermore, in each step of the heat treatment, the equipment is insulated by the heat-insulating shell 400 to reduce heat loss.

[0071] The root canal file body 001 obtained by the root canal file processing process provided by the embodiment of the present application has a better rigidity of the rod portion 012 of the root canal file, and the degree of deformation due to external force during rotation is smaller, which reduces shaking and makes the rotation accuracy of the blade higher; the filing blade of the root canal file body 001 has better flexibility and can be pre-bent to better adapt to the anatomical structure of the root canal; and can improve the guidance of the tip.
