Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to an arch wire torque plier. Background Art
[0002] Orthodontic brackets include brackets and arch wires. The brackets are connected to teeth, and the teeth are connected to the arch wire through the brackets, so that the traction force of the arch wire acts on the teeth through the brackets, enabling the teeth to move relative to the oral cavity. In actual operation, the operator will bend the arch wire according to the tooth morphology of different patients. The materials, thicknesses, and shapes of the arch wires used are not the same. At this time, the operator will apply corresponding forces to the arch wire using the characteristics of the arch wire itself to bend the arch wire to a preset angle.
[0003] However, in the prior art, when bending the arch wire, the operator bends the arch wire based on personal experience, and the operator cannot measure the bending angle of the arch wire, thus reducing the bending accuracy of the arch wire. Summary of the Utility Model
[0004] In order to solve the deficiencies of the prior art, the purpose of this application is to provide an arch wire torque plier that improves the accuracy of the arch wire.
[0005] To achieve the above purpose, the following technical solutions are adopted in this application:
[0006] An arch wire torque plier, which includes a plier body and a fixing structure. The fixing structure is used to fix two plier bodies and connects the two plier bodies. The arch wire torque plier further includes a measuring structure, which is connected to the plier body and is arranged around the fixing structure.
[0007] Further, the plier body includes a through portion, the fixing structure passes through the through portion, and the measuring structure is arranged around the contact portion between the through portion and the fixing structure.
[0008] Further, the plier body includes plier heads. The arch wire torque plier includes a measuring state and an initial state. When the arch wire torque plier is in the measuring state, the two plier heads are connected. When the arch wire torque plier is in the initial state, the two plier heads are separated.
[0009] Further, the measuring structure includes scales, which are connected to the plier body. A preset straight line is defined, and the preset straight line is set as the extension line of the connection portion of the two plier heads when the arch wire torque plier is in the measuring state. The scales include a starting position, and the starting position coincides with the extension line.
[0010] Further, the scales also include an ending position, and the value between the starting position and the ending position is set to 0° to 90°.
[0011] Further, when the arch wire torque plier is in the measuring state, both the starting position and the ending position coincide with the extension line.
[0012] Further, the value between the starting position and the ending position is set to be from 0° to 180°.
[0013] Further, the measuring structure includes a recessed portion, and the scale is arranged inside the recessed portion.
[0014] Further, the measuring structure includes a protruding portion, and the scale is arranged inside the protruding portion.
[0015] For the arch wire torque pliers provided by the present application, after an operator bends the arch wire to a preset angle, only by connecting the arch wire torque pliers to the bent portion and observing the value at the coincidence of the non-bent portion and the measuring structure, the value of the arch wire torque can be measured, enabling the operator to judge whether the bending degree is correct and timely adjust the bending angle of the arch wire, thereby making the bending degree of the arch wire precise.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.
[0021] As Figure 1 shown, the orthodontic bracket 100 includes a bracket body 11, a bracket base 12 and an arch wire 13. The bracket base 12 is connected to the tooth through an adhesive, the bracket body 11 and the bracket base 12 are connected, and the arch wire 13 is arranged inside the bracket body 11, so that the traction force of the arch wire 13 can be transmitted to the tooth through the bracket body 11 and the bracket base 12, enabling the tooth to move to a normal physiological position.
[0022] As Figure 2 shown, an arch wire torque pliers 200 includes a pliers body 21 and a fixing structure 22. The fixing structure 22 is used to fix the two pliers bodies 21, and the fixing structure 22 connects the two pliers bodies 21, so that the two pliers bodies 21 can rotate relative to each other, enabling the arch wire torque pliers 200 to disassemble orthodontic brackets 100 of different sizes, increasing the versatility of the arch wire torque pliers 200.
[0023] As Figures 1 to 4 shown, specifically, the arch wire torque pliers 200 further include a measuring structure 23. The measuring structure 23 is connected to the pliers body 21 and is disposed around the fixing structure 22. The arch wire 13 includes a bent portion and a non-bent portion. After the operator bends the arch wire 13 to a preset angle, only the arch wire torque pliers 200 need to be connected to the bent portion, and the value at the coincidence of the non-bent portion and the measuring structure 23 is observed to measure the torque value of the arch wire 13. Through the above setting, the measuring structure 23 is provided on the arch wire torque pliers 200, so that the arch wire torque pliers 200 can not only bend the arch wire 13, but also measure the torque of the arch wire 13, increasing the functions of the arch wire torque pliers 200 and diversifying the functions of the arch wire torque pliers 200. The setting of the measuring structure 23 also makes the bending degree of the arch wire 13 visible. The operator only needs to connect the bent portion to the arch wire torque pliers 200 and observe the value at the coincidence of the non-bent portion and the measuring structure 23 to directly observe the bending degree of the arch wire 13, so that the operator can judge whether the bending degree is correct and adjust the angle of bending the arch wire 13 in time, thereby making the bending degree of the arch wire 13 accurate.
[0024] As an implementation manner, the pliers body 21 includes a penetrating portion 211. The fixing structure 22 is disposed through the penetrating portion 211, and the measuring structure 23 is disposed around the contact portion of the penetrating portion 211 and the fixing structure 22. Through the above setting, the arch wire torque pliers 200 can measure the bent portion of the arch wire 13 without additional components, thereby reducing the mass of the arch wire torque pliers 200 and making the arch wire torque pliers 200 lightweight.
[0025] As an implementation manner, the pliers body 21 includes a pliers head 212. The arch wire torque pliers 200 include a measuring state and an initial state. When the arch wire torque pliers 200 are in the measuring state, the arch wire 13 is disposed between the two pliers heads 212. When the arch wire torque pliers 200 are in the initial state, the two pliers heads 212 are separated. Through the above setting, the pliers heads 212 can be connected and separated, so that the pliers heads 212 can adapt to the sizes of different arch wires 13, thereby improving the versatility of the arch wire torque pliers 200. The position of the pliers heads 212 is relatively close to the measuring structure 23, so there is no need to worry that the arch wire 13 is too short to measure the bending degree of the arch wire 13, thereby improving the convenience of measurement.
[0026] As an implementation, the measuring structure 23 includes a scale 231, which is connected to the pliers body 21 and defines a preset straight line. The preset straight line is set as the extension line 101 of the connection point of the two jaws 212 when the wire torque pliers 200 are in the measuring state. The scale 231 includes a starting position 232, and both the starting position 232 and the ending position 233 coincide with the extension line 101. Through the above settings, the measuring range of the bending degree of the wire 13 can be increased. When the bending angle of the wire 13 is too large or too small, the wire torque pliers 200 can measure the bending angle of the wire 13, thereby increasing the usage range of the bending angle of the wire 13 and also improving the practicality of the wire torque pliers 200.
[0027] Specifically, the scale 231 further includes an ending position 233, and the value between the starting position 232 and the ending position 233 is set to 0° to 90°. Through the above settings, the needs for measuring the bending angles of most wires 13 can be met.
[0028] As another implementation, when the wire torque pliers 200 are in the measuring state, both the starting position 232 and the ending position 233 coincide with the extension line 101. Through the above settings, the measuring range of the bending angle of the wire 13 can be expanded, and the applicable range of the wire torque of the wire 13 can be increased.
[0029] Specifically, the value between the starting position and the ending position 233 is set to 0° to 180°. Through the above settings, when the bending angle of the wire 13 is too large or too small, the wire torque pliers 200 can measure the bending angle of the wire 13.
[0030] As an implementation, the measuring structure 23 includes a recessed part (not shown in the figure), and the scale is arranged inside the recessed part. Through the above settings, when the wire torque pliers 200 are used for too long, the font on the surface of the wire torque pliers 200 may become blurred due to wear. The setting of the recessed part enables the operator to measure the bending angle of the wire 13 even when unable to judge the font on the surface.
[0031] As another implementation, the measuring structure 23 includes a protruding part (not shown in the figure), and the scale is arranged inside the protruding part. Through the above settings, when the wire torque pliers 200 are in the measuring state, the bent part of the wire 13 is arranged between the jaws 212, and the non-bent part of the wire 13 contacts the protruding part, so that the operator can further visually observe the specific angle of the bend of the wire 13, thereby further increasing the angle of the bend of the wire 13.
[0032] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of this application.
