Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to a wire end bending device for orthodontic treatment. Background Technology

[0002] In orthodontic treatment, after patients wear braces, the wires are shaped to fit the patient's oral cavity and then fixed in place to prevent tooth movement and achieve the corrective effect. Clinically, after changing wires, it is often necessary to bend the ends of the wires to prevent slippage and irritation to the mouth. The traditional method for bending the wire ends is to use a needle holder. However, because the needle holder head is relatively large, it can easily compress the corners of the mouth during bending, and the bending effect is often not ideal, potentially leading to buccal tube dislodgement. Therefore, relying solely on a needle holder for wire end bending is insufficient for satisfactory results. Therefore, there is an urgent need to develop a simple, easy-to-use wire end bending device for orthodontic use that provides excellent wire end bending performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wire end bending device for orthodontics that is simple in structure, easy to use, and has a good wire end bending effect.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a handle and a working end connected to the handle. The end of the working end is provided with a wire clamp. When working, the wire clamp is clamped at the end of the wire. At the same time, by rotating the handle, the working end is rotated, thereby causing the wire clamp to bend the end of the wire to the required degree.

[0005] Furthermore, the handle is cylindrical, and anti-slip protrusions are provided on the cylindrical surface of the handle.

[0006] Furthermore, the handle is provided with a first anti-slip area, a smooth area and a second anti-slip area in sequence along its length, and a plurality of anti-slip protrusions are evenly distributed on the first anti-slip area and the second anti-slip area.

[0007] Furthermore, the handle is provided with three equal zones along its length, namely the first anti-slip zone, the smooth zone, and the second anti-slip zone.

[0008] Furthermore, the handle is a cylinder with a diameter of 15mm and a length of 100mm.

[0009] Furthermore, the working end is cylindrical, the upper end of the working end is connected to the lower end of the handle, and the wire clamp is located at the lower end of the working end.

[0010] Furthermore, the working end is a cylinder with a diameter of 8mm and a length of 50mm. A transition section is provided between the upper end of the working end and the lower end of the handle. A flat section is provided at the lower end of the working end, and the wire clamp is located in the flat section.

[0011] Furthermore, the wire clip is a groove provided in the flat section, the upper opening of the groove has a width of 2mm and a depth of 4mm, and the opening width of the groove gradually increases from the outside to the inside.

[0012] Furthermore, the groove is a dovetail groove.

[0013] Furthermore, one side of the groove is a straight edge, and the other side of the groove is a beveled edge. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 4 As shown, in this embodiment, the present invention includes a handle 1 and a working end 2 connected to the handle 1. The working end 2 has a wire clamp 3 at its end. During operation, simply clamp the wire clamp 3 onto the end of the wire, and simultaneously rotate the handle 1 to rotate the working end 2, thereby bending the wire end to the required degree using the wire clamp 3. This easily achieves the bending operation of the wire end without complicated steps or additional tools, greatly improving work efficiency. In this embodiment, the handle 1 is cylindrical, and its cylindrical surface has anti-slip protrusions 4. The cylindrical shape of the handle conforms to the natural shape of the human hand, allowing the operator's hand muscles to be in a more relaxed state when holding the handle, reducing fatigue from prolonged operation and improving comfort. The anti-slip protrusions on the cylindrical surface of the handle increase the friction between the hand and the handle, ensuring a firm grip even when the hands are sweaty or in a wet environment, preventing the handle from slipping and improving operational safety and stability. Because of its simple structure, without complex gaps or dead corners, and because parts such as the wire clips are not prone to accumulating dust or debris, the tool is very easy to clean. Simply wipe it with a clean cloth, which reduces the maintenance cost and time of the tool.

[0016] In this embodiment, the handle 1 is a cylinder with a diameter of 15mm and a length of 100mm. This design conforms to ergonomic principles, making it easy for operators to hold and preventing excessive strain or discomfort during prolonged use. In this embodiment, the working end 2 is cylindrical, with its upper end connected to the lower end of the handle 1, and the wire clip 3 is located at the lower end of the working end 2.

[0017] like Figure 4 As shown, in this embodiment, the working end 2 is a cylinder with a diameter of 8mm and a length of 50mm. A transition section 8 is provided between the upper end of the working end 2 and the lower end of the handle 1. A flattened section 9 is provided at the lower end of the working end 2, and the wire clamp 3 is located on the flattened section 9. The transition section 8 between the upper end of the working end 2 and the lower end of the handle 1 makes the connection between the handle and the working end more natural and smooth, not only improving its appearance but also better transmitting torque in terms of mechanical performance, ensuring the stability and reliability of the working end's rotation. The flattened section 9 at the lower end of the working end 2, where the wire clamp is located, allows for a closer contact between the wire clamp and the wire, enabling better bending of the wire end and improving the accuracy and effectiveness of the operation.

[0018] In this embodiment, the wire clamp 3 is a groove located in the flat section 9. The upper opening of the groove has a width of 2mm and a depth of 4mm, and the opening width gradually increases from the outside to the inside. This size design can accommodate wire ends of different specifications, ensuring that the wire can be smoothly inserted into the groove and will not easily come out during bending. In this embodiment, the groove is a dovetail groove. One side of the dovetail groove is a straight edge, and the other side of the groove is a beveled edge. This structure provides stable support when bending the wire, while the beveled edge helps guide the wire to bend gradually, making the bending process smoother. At the same time, the special shape of the dovetail groove can also increase the friction between the wire and the clamp to a certain extent, preventing the wire from slipping during bending and ensuring bending quality.

[0019] In this embodiment, the handle 1 is provided with a first anti-slip area 5, a smooth area 6, and a second anti-slip area 7 sequentially along its length. Multiple anti-slip protrusions 4 are evenly distributed on both the first anti-slip area 5 and the second anti-slip area 7. In this embodiment, the handle 1 is provided with three equal-length areas sequentially along its length: the first anti-slip area 5, the smooth area 6, and the second anti-slip area 7. In this embodiment, the alternating design of the anti-slip and smooth areas allows the operator to bend the steel wire by rotating the cylindrical handle 1 to drive the working end 2. The operator can precisely control the angle and force of the handle rotation according to actual needs, thereby bending the end of the steel wire to the required degree, ensuring the quality and precision of the bending operation.

[0020] In clinical practice, this invention addresses the issue of wire slippage and puncture wounds after wire replacement by employing a wire end-bending device for wire retraction. This device effectively retracts the wire, achieving excellent results. Compared to traditional methods like needle holders, which, due to their larger heads, can compress the corners of the mouth during retraction, resulting in less effective retraction and potential irritation and dislodgement of the buccal tube, this invention significantly improves the wire retraction function. Its low technical barrier, rapid retraction speed, ease of operation, and positive patient experience make it easy to implement and widely applicable. Furthermore, its minimal discomfort and patient acceptance contribute to its widespread adoption.

[0021] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
