Description

Technical Field

[0001] This utility model relates to the field of instruments for hollow root canal treatment, specifically to a root canal file pre-bending tool. Background Technology

[0002] Root canal treatment is the preferred and effective method for treating pulpitis and periapical periodontitis, and for preserving the affected tooth. A root canal file is a medical instrument used in root canal treatment to thoroughly remove sources of infection from the root canal (this procedure is also called "root canal preparation"). Figure 5 As shown, the root canal file 1 consists of a file body 2 and a sliding limiting block 3 fitted onto the file body 2. The file body 2 has a handle 21 at the root and a tip 22 at the end. Figure 2 As shown, because root canals generally have complex three-dimensional structures, such as random bends, bifurcations, and confluences, the clinical use of root canal file 1 for root canal preparation of complex root canals presents challenges. Figure 6 As shown, the tip 22 needs to be pre-bent to adapt to the root canal shape. At the same time, the limiting block is slid along the file body. When adjusted to the target position, the distance between the limiting block 3 and the vertex of the tip 22 of the file body is the working length of the root canal file.

[0003] Chinese patent CN 215778776 U discloses a pre-bending forceps for root canal files. In use, the operator holds the handle of the forceps with one hand to open the jaws, and holds the handle of the root canal file with the other hand, placing the file body longitudinally into the first notch of the long jaw. Then, gently pressing the handle causes the jaws to close further. The root canal file bends under the combined action of the long and short jaws, thus completing the pre-bending of the root canal file.

[0004] However, using pre-bending forceps has the following disadvantages: 1. It is difficult to guarantee the accuracy of the pre-bending angle when using pre-bending forceps, which may cause the root canal file to not fully adapt to the curvature of the root canal, affecting the treatment effect. 2. Bending with pre-bending forceps requires repeated adjustments and verifications, increasing operation time and even potentially causing the root canal file to break. 3. Pre-bending forceps can only complete the pre-bending of the root canal file; the required working length needs to be achieved through subsequent independent operations. Utility Model Content

[0005] Based on this, and in response to the above problems, this utility model provides a root canal file pre-bending tool.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A root canal file pre-bending tool for bending root canal files into shape and fixing the working length includes a platform with multiple slots of different depths distributed on the platform. The portion of the root canal file inserted into the slot forms the working length. Each slot is closed on one side and has an opening on the other side extending to the edge of the platform. The bottom of the slot has a curved section that can force the root canal file to bend into shape.

[0008] Using the above technical solution, the bottom of the slot has a curved section. When the root canal file is inserted into the slot, the curved section can force the root canal file to bend into shape. The operation is simple, and the doctor can quickly complete the pre-bending without complicated skills. The bent root canal file can be taken out along the opening. In addition, the depth of each slot is different. In actual use, the doctor inserts the root canal file into the corresponding slot, and the part of the root canal file inserted into the slot forms the working length.

[0009] In a specific embodiment of this utility model: each of the slots has a positioning slot on its upper part, and each positioning slot is marked with a matching depth mark.

[0010] In a specific embodiment of this utility model, a base is also included, and the platform is fixed on the base.

[0011] In a specific embodiment of this utility model: the platform and the base are integrally formed.

[0012] In a specific embodiment of this utility model: the platform and the base are made of hard resin or hard metal.

[0013] In summary, this invention simplifies the operation by inserting the root canal file into the slot of the instrument panel. The curved section forces the file to bend and take shape, allowing for quick and easy operation without requiring complex skills. Furthermore, the varying depths of the slots allow the dentist to insert the file into the corresponding slot, with the inserted portion forming the desired working length. Thus, a single insertion completes both the bending and shaping of the root canal file and the determination of its working length. Additionally, each slot has a depth indicator near its positioning groove, facilitating direct observation by the dentist. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 and Figure 3 As shown, this utility model is a pre-bending tool for root canal files, used for bending and shaping root canal files 1 and fixing their working length. It includes a base 10 and a platform 11 fixed on the base 10. The base 10 provides support for the platform 11, ensuring stability during operation. In this embodiment, the platform 11 and the base 10 are integrally molded. The base 10 and the platform 11 are made of hard resin or hard metal.

[0023] like Figure 5 and Figure 6 As shown, the root canal file 1 consists of a file body 2 and a sliding retaining block 3 fitted onto the file body 2. The file body 2 has a handle 21 at the root and a pointed end 22 at the tip. The file body 2 also has external threads for easy cleaning of the root canal wall. It should be noted that the file body 2 is made of metal, and the retaining block 3 is made of elastic rubber. The retaining block 3 can slide with damping on the file body. When the retaining block is adjusted to the target position, the elastic deformation characteristics of the rubber material provide a reliable clamping force, thereby positioning the retaining block.

[0024] like Figure 3 and Figure 4As shown, the platform 11 has multiple slots 12 of varying depths. The upper part of each slot 12 has a positioning groove 121, and the bottom has a curved section 123 that forces the root canal file to bend into shape. The curvature of the curved section 123 can be set to 15°, 30°, 60°, or 90°. Thus, when the root canal file 1 is inserted into the slot 12, the curved section 123 forces the file to bend, simplifying the operation and allowing the dentist to quickly complete the pre-bending without complex techniques. Simultaneously, the dentist inserts the root canal file into the corresponding slot according to the actual situation; the portion of the file inserted into the slot forms the required working length, and the limiting block slides downwards to the positioning groove to complete the positioning.

[0025] In this embodiment, depth markings indicating the depth of the slot are marked near the positioning slot 121 of each slot 12, so that doctors can directly observe them.

[0026] like Figure 1 As shown, in this embodiment, the slot 12 is closed on one side and has an opening 13 extending to the edge of the platform 11 on the other side. In this way, when the root canal file 1 is inserted into the slot 12, it can be removed along the corresponding opening 13.

[0027] The above describes a pre-bending tool for root canal files according to this utility model. During operation, first, select the corresponding slot based on the required working length of the root canal file by observing the depth markings on the slot. Then, vertically insert the root canal file 1 into the selected slot; the curved section at the bottom of the slot forces the root canal file to bend into shape. Subsequently, slide the limiting block downwards along the file body to the positioning groove to complete positioning. Finally, remove the root canal file along the corresponding opening 13.

[0028] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
