Description

Technical Field

[0001] This utility model relates to the field of orthodontic instruments, specifically to a pre-formed ligature wire, which is a pre-formed ligature wire structure used to fix the bracket and archwire in an orthodontic appliance, and can be adapted to automated equipment for standardized ligation operations. Background Technology

[0002] In current orthodontic treatment, doctors typically use thin wire to manually ligate and fix the archwire to the brackets. This process involves multiple steps, including winding, tightening, and knotting, and heavily relies on the doctor's skill level, resulting in problems such as long processing time, poor consistency, and low efficiency. Furthermore, manual ligation is prone to uneven tension and wire tip curling, affecting patient comfort and treatment outcomes.

[0003] In recent years, as the orthodontic industry has moved towards digitalization and automation, the demand for standardized consumables that can automatically complete ligation procedures with the help of machines has been increasing. Therefore, there is an urgent need to develop a ligation wire that is structurally stable, easy to operate, and can be easily tightened to meet the needs of rapid, efficient, and standardized clinical procedures. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to overcome the shortcomings of existing ligation methods in terms of manual efficiency, fixation reliability and automation compatibility, and to provide a pre-formed ligation wire.

[0005] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes a main wire segment, a tail wire segment, and a connecting base arranged in sequence; the main wire segment and the tail wire segment are an integral component, the tail wire segment is located at the end of the main wire segment, the main wire segment is pre-bent to form an arc structure, used to wrap and fix the position between the orthodontic bracket and the archwire, the tail wire segment is fixedly connected to the connecting base, the connecting base is provided with a connection structure that can cooperate with a driving tool, and is provided with a clearance groove to facilitate the stacking, storage or transportation of multiple pre-formed ligature wires.

[0006] Preferably, both the main filament segment and the tail filament segment are made of medical-grade stainless steel wire.

[0007] Preferably, the connecting structure is any one of the following: a prismatic tube structure with an equilateral polygonal cross-section, a cylindrical structure with a positioning groove or limiting protrusion, and a cylindrical structure with edges, bayonets, or asymmetry.

[0008] Preferably, the connecting base is made of PC, PP or ABS plastic, with an outer diameter of 3-5 mm and a thickness of 1-3 mm.

[0009] Preferably, the tail wire segment is connected to the connecting base by hot riveting, injection molding, or mechanical pressing.

[0010] Preferably, the clearance groove is formed along the axial direction of the connecting base.

[0011] Preferably, when multiple preformed ligature wires are stacked for storage or transportation, for two adjacent preformed ligature wires, the main body segment and tail segment of the latter preformed ligature wire are located in the clearance groove of the former preformed ligature wire.

[0012] Compared with the prior art, this utility model has the following advantages: it can be adapted to automated equipment (electric tightening tool), which is convenient for mass industrial production. At the same time, after being adapted to automated equipment, it can improve the efficiency and fixation reliability of ligation work. In clinical practice, it only needs to be tightened after alignment and positioning, which greatly reduces the complexity of operation and training costs, and makes the operation more convenient. By designing the anti-cavity groove, it can support the vertical stacking of products, automatic sorting, mechanical feeding and other processes, reducing the risk of deformation during transportation and storage.

[0017] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0018] like Figures 1-4 As shown, this embodiment provides a technical solution: a pre-formed ligating wire, comprising: a main wire segment 1, a tail wire segment 2, and a connecting base 3, as detailed below:

[0019] The main wire segment 1 is made of medical metal wire and is pre-bent into a U-shape, C-shape or other arc structure to wrap around and fix the position between the orthodontic bracket and the archwire;

[0020] In this embodiment, the main wire segment 1 is selected from a medical stainless steel wire with a diameter of 0.25mm, which is pre-bent into a U-shaped structure to wrap around and fix the position between the orthodontic bracket and the archwire.

[0021] Tail segment 2 extends from the end of the main body segment 1 and is an integral part thereto. It is located at both ends of the main body segment 1 and is used to form the final cross-tightening structure. It is a key part for performing the ligation force application action.

[0022] The connecting base 3 is located at the end of the tail section 2 and has a connecting structure 31 that can engage with the driving tool for transmission. It can also achieve anti-slip engagement with the external driving tool to ensure that slippage or misalignment is prevented during rotational drive. The connecting structure 31 includes, but is not limited to: a prismatic structure with an equilateral polygonal cross-section (such as a regular hexagon, regular octagon, regular pentagon, etc.), a cylindrical structure with a positioning groove or limiting protrusion, and an irregular cylindrical structure with edges, bayonet, or asymmetrical features.

[0023] In this embodiment, the connecting base 3 is made of medical-grade polycarbonate (PC), polypropylene (PP) or ABS plastic, which has good rigidity and biocompatibility, with an outer diameter of 3-5 mm and a thickness of 1-3 mm.

[0024] In this embodiment, the tail wire segment 2 and the connecting base 3 are connected by hot riveting, injection molding, or mechanical pressing.

[0025] In this embodiment, the connecting base 3 is provided with a through hole 32, and the tail wire segment 2 is inserted into it and then fixedly connected by hot riveting, injection molding or mechanical pressing.

[0026] In this embodiment, the outer surface of the connecting base 3 is provided with positioning marks, QR codes or directional textures to quickly determine the position and orientation of the product, facilitating rapid loading.

[0027] In this embodiment, the connecting structure 31 of the connecting base 3 is a cylindrical structure with a regular hexagonal cross-section, having 6 mating sides that mate with the driving tool.

[0028] In this embodiment, the connecting base 3 is provided with an axial clearance groove 4, which is used to avoid the section of the wire formed by the main wire segment 1 and the tail wire segment 2 in the adjacent preformed ligature wires when multiple preformed ligature wires are stacked for storage or transportation, so as to prevent compression deformation and improve stacking stability and structural integrity.

[0029] It should be noted that the driving tool is an electric tightening tool with an irregularly shaped sleeve (matching the outline of the connecting structure 31). After being inserted into the connecting base 3, it drives the base to rotate, thereby achieving the winding action and completing the fixation.

[0030] In summary, this pre-formed ligation wire is compatible with automated equipment (electric tightening tools), facilitating mass industrial production. Furthermore, its compatibility with automated equipment improves ligation efficiency and fixation reliability. In clinical practice, it only requires alignment and tightening, significantly reducing operational complexity and training costs, making operation much simpler. The design of the clearance groove supports vertical stacking, automated sorting, and mechanical feeding processes, reducing the risk of deformation during transportation and storage.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
