[0019] The technical solutions of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0020] REFERENCE Figure 1 , 2The utility model provides a kind of orthodontic ligature wire forming auxiliary tool, including parallelly arranged first cross bar 1 and second cross bar 2, the first cross bar 1 is connected with second cross bar 2 by connecting rod 3, the vertical section of second cross bar 2 is the shape of middle wide, narrow up and down.
[0021] The utility model discloses a kind of orthodontic ligature wire 6 are wound several turns on first cross bar 1 and second cross bar 2, then ligature wire 6 is pressed into the shape of middle wide, narrow up and down two ends in second cross bar 2 part, finally preformed ligature wire 6 is taken out from tool and cut off, multiple single formed ligature wire 6 can be obtained, to improve the forming efficiency of ligature wire 6, and it is easy to operate.
[0022] Specifically, the vertical section shape of the second cross bar 2 is diamond, "X" or oval, and the four edges of the second cross bar 2 are designed as chamfered structures 4. The vertical section shape of the second cross bar 2 is the shape of the formed ligature wire 6.
[0023] Further preferably, the vertical section shape of the second cross bar 2 is diamond. The ligature wire 6 with this shape is most convenient to use in clinical operations.
[0024] When the vertical section of the second cross bar 2 is designed as a prismatic shape, the four edges of the second cross bar 2 should be designed as rounded corners to avoid cutting the ligature wire 6 and causing it to break during the winding and preforming process.
[0025] When the vertical section shape of the second cross bar 2 is "X", the four corners of the intersection part are designed as rounded corners. The purpose of this design is to prevent the middle part of the formed ligature wire 6 from being too small to be conveniently fitted on the groove of the bracket.
[0026] Preferably, the second cross bar 2 is longer than the first cross bar 1, and the part of the second cross bar 2 beyond the first cross bar 1 serves as a holding part 5, which facilitates holding the tool for operation.
[0027] In the specific implementation process, the first cross bar 1 can also be designed to be longer than the second cross bar 2, and the part of the first cross bar 1 beyond the second cross bar 2 serves as the holding part 5.
[0028] Preferably, the first cross bar 1, the connecting rod 3, and the second cross bar 2 are integrally cast into a shape, which is more stable and less likely to be deformed or damaged.
[0029] Specifically, the surfaces of the first cross bar 1 and the second cross bar 2 are provided with anti-slip patterns, which can prevent the ligature wire 6 from slipping on the surfaces of the first cross bar 1 or the second cross bar 2 during winding. This design makes the ligature wire 6 more stable during winding, avoiding uneven forming or operation failure caused by slipping.
[0030] The material of the auxiliary tool in the embodiment is medical-grade stainless steel or other materials meeting the standards of medical devices, to ensure its safety and durability.
[0031] When the forming operation of the ligature wire 6 is performed using the tool of the present application, the ligature wire 6 is first wound several turns on the first cross bar 1 and the second cross bar 2, as shown in FIG. 4. Figure 3 When winding, attention should be paid to the moderate tension of the ligature wire 6 to avoid being too tight or too loose. Then, the ligature wire 6 is pressed into a shape with a wide middle and narrow upper and lower ends (so that the ligature wire 6 closely adheres to the outer wall of the second cross bar 2) at the second cross bar 2 part. Special pressing tools can be used for pressing or the ligature wire 6 can be directly pressed by hand to ensure that the shape of the ligature wire 6 is uniform and consistent. Finally, the pre-formed ligature wire 6 is taken out of the tool, as shown in FIG. 5, and is cut off at the top 1-2 cm of the pre-formed ligature wire 6 at one time, so that a plurality of single formed ligature wires 6 can be obtained, as shown in FIG. 6. These formed ligature wires 6 can be directly used for clinical operation, greatly improving the forming efficiency of the ligature wire 6 and the convenience of operation. Figure 4 Figure 5
