Description

Technical Field

[0001] This utility model relates to the field of root canal file disassembly tools, and more particularly to a root canal file disassembly tool. Background Technology

[0002] Root canal files are commonly used instruments in dental treatment. They generally consist of a file and a holder. The holder is usually fitted onto the blunt end of the file. However, during the manufacturing process, the holder needs to be clamped and fitted onto the file, which can easily damage the surface of the holder, resulting in defective products. Defective products are usually reworked, which involves separating the file from the holder and inserting a new holder. Separating the file from the holder is usually done manually, which can easily lead to bending of the file, ultimately rendering both the file and the holder unusable, wasting materials and increasing production costs. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a root canal file disassembly tool.

[0004] This utility model is achieved using the following technical solution: a root canal file disassembly tool, comprising a frame, a lifting component on the end face of the frame, a clamping component below the frame, an insertion disc for inserting a root canal file on the end face of the frame, a socket for inserting the root canal file at the center of the insertion disc, the clamping component communicating with the socket, the diameter of the socket being larger than the diameter of the file needle of the root canal file and smaller than the diameter of the needle-holding part of the root canal file, the file needle of the root canal file passing through the socket and inserted into the clamping component and clamped by the clamping component, the insertion disc being fixed on the lifting component, and the lifting component driving the insertion disc to lift when the clamping component clamps the file needle of the root canal file.

[0005] The periphery of the insertion hole forms a slope towards the center of the insertion hole.

[0006] The lifting assembly includes a linear drive device fixed to the frame, and the drive shaft of the linear drive device pushes the insertion disk to lift.

[0007] The clamping assembly is a three-jaw chuck, and the center of the jaws of the three-jaw chuck is coaxial with the insertion hole.

[0008] The frame includes support legs and an upper platform. The platform is mounted on the support legs, the insertion disk is fixed on the upper platform, and the linear drive device drives the upper platform to rise and fall.

[0009] The top of the support leg forms a downward groove for placing the upper platform. The edge of the upper platform engages in the groove. The middle of the support leg fixes the lower platform. The linear drive device and the three-jaw chuck are respectively fixed on the lower platform.

[0010] Compared to existing technologies, this invention involves directly inserting the file portion of the root canal file to be disassembled into the insertion hole in the center of the insertion disc. This ensures that a portion of the upper end of the file (the end opposite the tip) can be inserted into the three-jaw chuck. The three-jaw chuck then clamps the upper end of the file, and the linear drive mechanism pushes the insertion disc upwards, separating the needle holder from the file. During separation, the force is evenly distributed, and because neither the three-jaw chuck nor the insertion disc contacts the tip of the file (the part actually used for treatment) throughout the process, damage to the file is minimal. The separated file can be reattached to a suitable needle holder for reuse, reducing material waste and lowering costs. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Reference Figure 1-2A root canal file disassembly tool includes a frame 1. In this embodiment, the frame 1 is divided into two layers and supported by support legs 13, with an upper platform 11 positioned above the support legs 13. In this embodiment, the upper platform 11 needs to be raised and lowered, therefore a fixed connection cannot be used between it and the support legs 13. In this embodiment, a groove corresponding to the edge shape of the upper platform 11 can be formed on the end face of the support legs 13, allowing the corner of the upper platform 11 to be directly placed within the groove when it is placed on the support legs 13. A lower platform 12 is fixed to the middle of the support legs and is parallel to the upper platform 11. A lifting assembly can be fixed to the lower platform 12 to move the upper platform 11. An insertion plate 4 is fixed to the upper platform 11, with an insertion hole 5 at its center. The insertion hole 5 directly penetrates the upper platform 11. Similarly, a clamping assembly can be fixed to the lower platform 12 and opposite to the insertion hole 5. When a damaged root canal file is inserted into the insertion hole 5, it can be inserted through the insertion plate 4. Specifically, the tip of the root canal file is directly inserted into the insertion hole 5 and passes through the clamping assembly, allowing the blunt end of the file to be inserted into the clamping assembly for clamping. After clamping, the lifting assembly pushes the upper platform 11 upward, thus separating the file from the holding part. Throughout the separation process, neither the clamping assembly nor the insertion plate 4 makes any contact with the tip of the file (i.e., the part actually used for treatment). Therefore, the damage to the file is minimal during separation, and the separated file can be reattached to a suitable holding part for reuse, reducing material waste and lowering costs.

[0016] In this embodiment, the inner diameter of the insertion hole 5 is between the diameter of the needle holding part and the diameter of the blunt end of the file. This way, after the root canal file is inserted, the lower end face of the needle holding part can abut against the end of the insertion hole 5. Thus, during the entire lifting process, only the needle holding part is moved without affecting the file. During the separation process, the lower end of the entire needle holding part is the bearing end, and the damage to the file is small. The separated file can be re-inserted into a qualified needle holding part for reuse, reducing material waste and lowering costs.

[0017] The lifting assembly in this embodiment includes at least a linear drive device 2. The linear drive device 2 can be a common linear drive device such as a cylinder, hydraulic cylinder, or electric actuator. Its drive shaft is connected to the lower end of the upper platform 11 to push the upper platform 11 to move. In this embodiment, the stroke of the upper platform 11 is equal to or slightly less than the depth of the groove opened on the support leg 13. In this state, when the upper platform 11 reaches its maximum stroke, a part of it will still be in the groove. That is, the groove plays a limiting role throughout the stroke, so as to make the formation process more stable.

[0018] In this embodiment, a slope 6 is formed on the periphery of the insertion hole 5 towards its center to mark the insertion hole 5 for easy identification by the user. Simultaneously, the clamping component in this embodiment is a three-jaw chuck 3, with the centers of the jaws of the three-jaw chuck 3 coaxial with the insertion hole 5. This allows the tip of the root canal file to pass through the insertion hole 5 and directly into the three-jaw chuck 3, with the upper end of the three-jaw chuck 3 as close as possible to the bottom of the insertion hole 5. At this point, a portion of the blunt end of the file can be inserted into the three-jaw chuck 3 for clamping. This ensures that the clamping of the file by the three-jaw chuck 3 will not affect the tip of the file (i.e., the part used for root canal treatment), reducing the possibility of file damage.

[0019] Compared to existing technologies, this invention involves directly inserting the file portion of the root canal file to be disassembled into the insertion hole 5 in the middle of the insertion disc 4. This ensures that a portion of the upper end (the end opposite the tip) of the file can be inserted into the three-jaw chuck 3. Subsequently, the three-jaw chuck 3 clamps the upper end of the file, and the linear drive device 2 pushes the insertion disc 4 upward to separate the needle holder from the file. During the separation process, the force is evenly distributed, and because neither the three-jaw chuck 3 nor the insertion disc 4 makes any contact with the tip of the file (i.e., the part actually used for treatment) during the entire separation process, the damage to the file is minimal. The separated file can be reattached to a suitable needle holder for reuse, reducing material waste and lowering costs.

[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
