[0045] 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. The root canal file can remove the material in the root canal or gradually expand the root canal passage by rotating, squeezing, etc. However, the structure of the root canal file is relatively simple. It is difficult to completely remove the decay of the root canal wall during oral treatment, resulting in incomplete root canal treatment. Therefore, the utility model provides a file body and a root canal file for human root canal retreatment.
[0046] The following is a detailed introduction to an embodiment of a file body for human root canal retreatment according to the utility model.
[0047] See also Figure 1 and 2 The present embodiment provides a file body for human root canal retreatment, comprising a file body 10; a treatment section 11 is disposed at one end of the file body 10; the treatment section 11 has at least one barb 16, the barb 16 extends in a direction away from the treatment section 11, and the barb 16 forms an acute angle with the axis extension direction of the treatment section 11 close to the file body 10, and the barb 16 is suitable for treating human root canals.
[0048] It should be noted that the file body 10 is a thin strip-shaped structure with a certain length, and the treatment section 11 is a part of the file body 10 near its end. The treatment section 11 is the main area of the file body 10 for implementing root canal treatment, and at least one barb 16 is provided on the treatment section 11. The angle between the barb 16 and the file body 10 is consistent with the extension direction of the end of the file body 10, that is, the barb 16 forms an acute angle with the extension direction of the axis of the treatment section 11 near the file body 10.
[0049] When the file body of this embodiment is actually used, medical personnel place the treatment section 11 of the file body 10 in the root canal, and the barbs 16 enter the root canal along the acute angle direction formed by the barbs 16 and the file body 10. The direction of the acute angle formed by the barbs 16 is consistent with the direction of movement of the file body 10. When cleaning the material to be cleaned in the root canal (such as the residual pulp in the root canal and the decay of the root canal wall), the barbs 16 are combined with the material to be cleaned by rotating, etc., and the combined material to be cleaned is hooked out of the file body 10 by the barbs 16. At this time, the direction of the acute angle formed by the barbs 16 is opposite to the direction of movement of the file body 10, and the combined residual pulp or decay can be cleaned out of the root canal by the barbs 16. The file body of this embodiment can be used in conjunction with other types of root canal files, and a better root canal retreatment effect can be achieved by repeated use and cleaning.
[0050] In some embodiments, the acute angle between the barb 16 and the treatment section 11 is between 15° and 45°.
[0051] In some embodiments, there are multiple barbs 16, and the multiple barbs 16 are arranged at intervals along the axial direction of the treatment section 11. Figure 2 As shown, the angles formed between the multiple barbs 16 arranged in the axial direction of the treatment section 11 and the file body 10 are all in the same direction. Compared with one barb 16, multiple barbs 16 arranged in the same direction have better cleaning effect and efficiency during root canal treatment.
[0052] In some embodiments, the number of the barbs 16 is multiple, and the multiple barbs 16 are symmetrically arranged along the axial direction of the treatment section 11. Figure 3 As shown, a plurality of barbs 16 are symmetrically arranged on the treatment section 11, and the barbs 16 in the same direction are arranged in sequence and at intervals. When the residual pulp or decayed matter in the root canal is cleaned in a rotating manner, the symmetrically arranged barbs 16 have better cleaning effect and efficiency.
[0053] In some embodiments, the distance between any two adjacent barbs 16 is between 0.1 mm and (L / (N-1)) mm, wherein N is the number of barbs 16 in the axial direction of the treatment section 11, and L is the length of the operation area, in mm. In this embodiment, the length of the operation area is preferably set to 15 mm. Considering the relationship between the number of barbs 16 and the cleaning effect and the process manufacturing limitations of the file body, in this embodiment, the spacing range of the barbs 16 is set to be between 0.1 mm and 15 / N mm. For example, when 6 barbs 16 are set along the axial direction of the treatment section 11, the maximum spacing between the barbs 16 does not exceed 3 mm. The design of barbs 16 with appropriate spacing can balance the relationship between the cleaning effect and the manufacturing of the file body.
[0054] In some embodiments, the barbs 16 are disposed in the operation area, which is a portion of the treatment segment located at the end and having a certain length. The axial length of the operation area can be between 15 mm and 18 mm, and the axial length of the treatment segment 11 can be between 21 mm and 31 mm, and the above dimensions can be specifically selected according to the body shape of the human body.
[0055] In some embodiments, the file body further includes: a fixing section 15; the fixing section 15 is arranged at the other end of the file body, and the axis extension direction of the fixing section 15 forms an angle with the axis extension direction of the treatment section 11, and the fixing section 15 is suitable for installing the file body. The fixing section 15 and the treatment section 11 are respectively arranged at two opposite ends of the file body, and the axis extension direction of the fixing section 15 forms an angle with the axis extension direction of the treatment section 11, which means that the file body has at least one bending angle, that is, the file body is a bending structure. Figure 2 and 3 The file body of this embodiment is introduced.
[0056] The file body 10 includes a treatment section 11, a connecting section 13 and a fixing section 15; the connecting section 13 is located between the treatment section 11 and the fixing section 15; and at least one bending angle is a first bending angle 12 and / or a second bending angle 14 between the connecting section 13 and the treatment section 11. Figure 2 The file body 10 has a fixed section 15, a connecting section 13 and a treatment section 11, wherein opposite ends of the connecting section 13 are fixedly connected to the fixed section 15 and the treatment section 11 respectively, and the fixed section 15 is used to be inserted into the clamping member 20 of the handle 40, so that the file body 10 and the handle 40 can be fixedly connected as a whole. The first bending angle 12 is close to the treatment section 11 of the file body 10, and the second bending angle 14 is close to the fixed section 15 of the file body 10. The file body 10 has at least one bending angle between the fixed section 15, the connecting section 13 and the treatment section 11, so that a certain angle is formed between the file body 10 and the handle 40.
[0057] In some embodiments, the size of the first bending angle 12 is between 80° and 135°, and the size of the second bending angle 14 is between 25° and 35°. The angles of the first bending angle 12 and the second bending angle 14 can be manually adjusted by the operator according to the size of the animal, the condition of the teeth, etc., and can be specifically adjusted according to the opening degree or the extension of the animal. In other embodiments, the material of the file body 10 can be stainless steel or nickel-titanium alloy, which can ensure that the life of the file body 10 is long and stable and reliable. When the file body with a bending structure is actually used, the working principle of cleaning the residual medulla and decay in the root canal through the treatment section 11 is consistent with the above-mentioned embodiment, except that the file body 10 with a bending structure is more convenient for medical personnel to operate at different angles.
[0058] In some embodiments, the construction material of the file body 10 is stainless steel or nickel-titanium alloy, which can ensure that the file body has a long life and is stable and reliable.
[0059] The above is a detailed introduction to a file body for human root canal retreatment of the utility model. The following is a detailed introduction to a root canal file of the utility model.
[0060] The utility model provides a root canal file, comprising: a file body, which is a file body used for human root canal retreatment according to the above embodiment; and a handle assembly, which is connected to the file body so as to control the file body to treat the human root canal by operating the handle assembly.
[0061] When the root canal file of this embodiment is used, the file body is first mounted on the handle assembly, and the medical staff operates the root canal file by holding the handle assembly to treat the human root canal through the file body.
[0062] In some embodiments, the handle assembly includes: a handle body; the handle body is provided with anti-slip texture. Figure 4 Considering the influence of the stability of the root canal file on the tooth treatment, the handle 40 is preferably ergonomically designed. A clamping member 20 is provided at one end of the handle 40 for mounting the file body 10 structure. The handle 40 is provided with anti-skid anti-skid patterns, which facilitate the doctor to hold the root canal file during operation and effectively prevent the root canal file from moving.
[0063] In some embodiments, the handle assembly further includes: a fixing assembly; the fixing assembly includes a clamping member 20 and a fixing member 30; the clamping member 20 is disposed at one end of the handle body, and the clamping member 20 is provided with a mounting portion that is adapted to the shape of the end of the file body away from the treatment section 11; the fixing member 30 is disposed on the clamping member 20, and is suitable for fixing the end of the file body away from the treatment section 11 in the mounting portion of the clamping member 20. Figure 5 and 6 As shown, one end of the clamping member 20 is constructed into two semicircular clamping plates 21; the two semicircular clamping plates 21 are symmetrically provided with a gap 22, and the two semicircular clamping plates 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 member 20; and the fixing section 15 is inserted and installed between the two semicircular clamping plates 21.
[0064] See also Figure 5 and 6, a cylindrical space is formed between the two semicircular clamping pieces 21, and the bottom of the cylindrical space is considered, and the fixed section 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 pieces 21, and the outer surface is provided with an external thread. The fixing piece 30 is movably mounted on one end of the clamping piece 20, and the fixing piece 30 can fix the file body 10 on the clamping piece 20, so that the file body 10 and the handle are fixedly connected together. The interior of the fixing piece 30 is provided with an external thread, and the exterior of the clamping piece 20 is provided with an external thread opposite to the internal thread, so that the fixing is performed by a threaded connection. When the fixing piece 30 is threadedly connected with the two semicircular clamping pieces 21, the gap 22 between the two semicircular clamping pieces 21 is gradually reduced, thereby reducing the size of the cylindrical space, so that the file body 10 is stably fixed and installed in the clamping piece 20. The lower end of the clamping piece 20 can be integrally formed with the 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.
[0065] 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 7 The wrench tweezers 50 are shown.
[0066] 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.
