[0049] Generally, a root canal file is a long, slender instrument with a handle at one end and a metal head with file teeth at the other end. It can remove the material in the root canal or gradually expand the channel of the root canal by rotating, squeezing, etc. However, due to the special structure of animal teeth, the structure of the root canal file in the prior art is relatively simple, and the root canal file is integrally formed in the form of injection molding, which has poor versatility and cannot be effectively applied to animal tooth treatment. Therefore, the utility model provides a root canal file for animal tooth treatment.

[0050] The following is a detailed introduction to an embodiment of a root canal file for animal tooth treatment according to the utility model.

[0051] See also Figure 1 The present embodiment provides a root canal file for animal tooth treatment, comprising a file body 10, a fixing member 30 and a file handle 40; one end of the file body 10 is an operating portion 11, and the other end is a mounting end 15; the end of the operating portion 11 is a threaded structure; a first bending angle is provided between the operating portion 11 and the mounting end 15; the size of the first bending angle is between 80°-135°; a clamping portion 20 is provided at one end of the file handle 40; the fixing member 30 is mounted on the clamping portion 20; the mounting end 15 is inserted and mounted in the clamping portion 20; the extending direction of the operating portion 11 forms an angle with the axial direction of the file handle 40.

[0052] It should be noted that the file body 10 is the main part of the root canal file for implementing tooth treatment. The common file body 10 is in a long strip shape and is an integrally formed structure with the file handle 40. In order to improve the versatility of the root canal file in the process of treating teeth of different animals, the file body 10 and the file handle 40 are designed separately in this embodiment.

[0053] The main purpose of animal root canal treatment is to remove pulp tissue, remove infection in the pulp, and repair the crown, in order to solve nerve pain, preserve teeth or treat tooth roots. In this embodiment, the end of the operating part 11 is a threaded structure, which is more suitable for animal tooth treatment. The file body 10 and the file handle 40 are fixedly connected by clamping. Specifically, the mounting end 15 of the file body 10 is inserted into the clamping part 20 of the file handle 40, and then the mounting end 15 in the clamping part 20 is fixed by the fixing member 30 to ensure that the file body 10 is partially stable relative to the file handle 40 during tooth treatment. The advantage of the file handle 40 using a clamping method to install the file body 10 is that file bodies 10 of different sizes can be installed on this type of file handle 40, which improves the versatility of the root canal file.

[0054] In addition, the file body 10 also has a first bending angle, that is, the file body 10 is a bent structure. Due to the large differences in tooth structures between different animals, in order to further improve the scope of application of the root canal file, an angle is provided between the operating portion 11 of the file body 10 and the file handle 40, thereby distinguishing it from a traditional long strip root canal file and making it more suitable for animal tooth treatment. For example, when an animal's gums become inflamed, the oral opening may be limited. Compared with a traditional long strip root canal file, the file body 10 with a bent structure can treat the animal's teeth when the oral opening is limited.

[0055] When the root canal file of this embodiment is actually used, the mounting end 15 of the file body 10 is first inserted into the clamping portion 20 of the file handle 40, and then the fixing member 30 is operated to fix the file body 10. The fixed file body 10 is stably connected to the file handle 40. Medical personnel perform corresponding dental treatment operations through the operating portion 11 of the file body 10.

[0056] This embodiment provides a root canal file for animal tooth treatment, which adopts a bent design of the file body 10 and is particularly suitable for animal tooth treatment. At the same time, the file handle 40 is fixedly clamped by the fixing member 30 to clamp the file bodies 10 of different sizes, which can facilitate medical personnel to quickly replace the file bodies 10 of different sizes according to actual use, and has good versatility.

[0057] In one embodiment of the present invention, the file body 10 further includes a connecting portion 13; the connecting portion 13 is located between the operating portion 11 and the mounting end 15; the first bending angle is located between the connecting portion 13 and the operating portion 11, and a second bending angle 14 is also provided between the connecting portion 13 and the mounting end 15. Figure 2The file body 10 has a mounting end 15, a connecting portion 13 and an operating portion 11, wherein the two opposite ends of the connecting portion 13 are fixedly connected to the mounting end 15 and the operating portion 11 respectively, and the mounting end 15 is used to be inserted into the clamping portion 20 of the file handle 40, so that the file body 10 and the file handle 40 can be fixedly connected as a whole. The first bending angle 12 is close to the operating portion 11 of the file body 10, and the second bending angle 14 is close to the mounting end 15 of the file body 10. The file body 10 has at least one bending angle between the mounting end 15, the connecting portion 13 and the operating portion 11, so that a certain angle is formed between the file body 10 and the file handle 40.

[0058] In some embodiments, the second bending angle 14 is between 145° and 155°, and the angles of the first bending angle 12 and the second bending angle 14 can be manually adjusted by the operator according to the animal's body shape, tooth condition, etc., and can be specifically adjusted according to the opening degree or extension of the animal. In other embodiments, the file body 10 can be made of stainless steel or nickel-titanium alloy, which can ensure that the file body 10 has a long life and is stable and reliable.

[0059] In one embodiment of the utility model, one end of the clamping portion 20 is constructed into two semicircular clamping members 21; the two semicircular clamping members 21 are symmetrically arranged with a gap 22, and the two semicircular clamping members 21 are provided with external threads; the fixing member 30 is provided with an internal thread; the fixing member 30 is threadedly connected to the clamping portion 20; and the mounting end 15 is inserted and installed between the two semicircular clamping members 21.

[0060] See also Figure 3 , a cylindrical space is formed between the two semicircular clamping members 21, and the bottom of the cylindrical space is considered, and the mounting end 15 of the file body 10 of different sizes can be inserted and installed in the cylindrical space. There is a certain gap 22 between the two semicircular clamping members 21, and the outer surface is provided with an external thread. The fixing member 30 is movably mounted on one end of the clamping end, and the fixing member 30 can fix the file body 10 on the clamping part 20, so that the file body 10 and the handle are fixedly connected together. The interior of the fixing member 30 is provided with an external thread, and the exterior of the clamping end is provided with an external thread opposite to the internal thread, so that the file body 10 is fixed by a threaded connection. When the fixing member 30 is threadedly connected with the two semicircular clamping members 21, the gap 22 between the two semicircular clamping members 21 is slowly reduced, thereby reducing the size of the cylindrical space, so that the file body 10 is stably fixed and installed in the clamping part 20. The lower end of the clamping part 20 can be integrally formed with the file handle 40. It can be seen that this installation method is suitable for file bodies 10 of different sizes. It is convenient for subsequent doctors to disassemble the fixing piece 30 according to actual use, so as to quickly replace the file body 10 of different sizes. The fixing piece 30 can be constructed as a metal piece, such as stainless steel, aluminum, etc., which can effectively increase the service life of the fixing piece 30 and greatly improve the stability and reliability of the fixing piece 30.

[0061] In one embodiment of the present invention, the file handle 40 is an integrally formed structure, and a convex pattern structure is provided on the file handle 40. Figure 4 Considering the influence of the stability of the root canal file on the tooth treatment, the file handle 40 is preferably ergonomically designed. A clamping portion 20 is provided at one end of the file handle 40 for mounting the file body 10 structure. The file handle 40 is provided with an anti-slip convex structure, which makes it easier for the doctor to hold the root canal file during operation and effectively prevents the root canal file from moving.

[0062] In some embodiments, the file handle 40 is made of metal, such as stainless steel, aluminum, etc., which can effectively increase the service life of the handle and significantly improve the stability and reliability of the file handle 40. In other embodiments, the file handle 40 can be made of plastic, which can effectively reduce the production cost of the root canal file.

[0063] like Figure 5 As shown, in one embodiment of the present invention, the fixing member 30 can be configured as a tubular structure. When in use, the clamping portion 20 is located inside the tubular structure of the fixing member 30 .

[0064] In one embodiment of the present invention, the operating portion 11 includes: a working area 16; and a threaded structure is arranged in the working area 16. Figure 2 As shown, the working area 16 is a part of the operating part 11 of the file body 10, and the working area 16 is used to perform treatment operations on teeth. The axial length of the working area 16 is between 15 mm and 200 mm, and the axial length of the operating part 11 is between 15 mm and 300 mm. The above dimensions can be selected according to the size of the animal. For example, when treating a small animal (cat), 15 mm can be selected, and when treating a large animal (dog), 60 mm can be selected.

[0065] In some embodiments, the thread structure in the operating portion 11 adopts a first thread structure or a second thread structure, the pitch of the first thread structure is between 0.2 mm and 1.5 mm, and the pitch of the second thread structure is between 1.5 mm and 3 mm. That is, according to the density of the thread, a file body 10 structure with denser threads and a file body 10 structure with sparser threads can be obtained.

[0066] In addition, when the doctor subsequently replaces a different file body 10, in order to ensure that the root canal file is not contaminated, an auxiliary tool can be used for replacement. Figure 6 The wrench tweezers 50 are shown.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
