Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bending device for rectangular twisted tongue-side wires. Background Technology

[0002] Maintaining stability after orthodontic treatment is a challenge for orthodontists. Preventing relapse of malocclusion is equally important after active orthodontic treatment. To consolidate the effects of orthodontic treatment and reduce or avoid relapse, retainers are used to keep teeth in the ideal position and prevent movement. Retainers must be worn for a certain period of time; otherwise, the teeth and jawbone may shift back to their pre-orthodontic positions.

[0003] Among fixed and removable retainers, fixed lingual wire retainers are independent of patient compliance, have the longest retention time, minimal impact on pronunciation, and less foreign body sensation. Therefore, choosing a lingual wire is a good option for retention after orthodontic treatment. When fabricating a lingual wire retainer, the clinician needs to bend it according to the patient's oral condition before transferring it to the patient's mouth for subsequent bonding and fixation. However, there is currently a lack of specialized rectangular twisted lingual wire bending instruments. Using ordinary tools such as pin holders for bending is inefficient and also affects the fit of the lingual wire after bending.

[0004] Based on the above background, the inventors designed a bending tool for rectangular twisted tongue-side strands, which solves at least one of the above problems, and thus, this application is filed. Utility Model Content

[0032] like Figures 1 to 3As shown, this embodiment provides a bending tool for rectangular twisted tongue-side strands, including a first support 1 and a second support 2 rotatably connected. The first support 1 has a first gripping portion 11 and a first clamping portion 12 at both ends, and the second support 2 has a second gripping portion 21 and a second clamping portion 22 at both ends, wherein:

[0033] The first gripping part 11 and / or the second gripping part 21 are provided with a bending structure for bending the straight rectangular twisted tongue side wire into a U-shape.

[0034] The first clamping part 12 and the second clamping part 22 are provided with a bulge forming structure assembly that cooperates with each other to clamp and press out a bulge shape on the U-shaped rectangular twisted tongue side wire.

[0035] In this embodiment, a bending groove 111 is provided on the first gripping part 11 and / or the second gripping part 21. The bending groove 111 allows a portion of the straight rectangular twisted tongue wire to be placed into the bending groove 111. As the sliding forming ring 3 slides on the first gripping part 11 and the second gripping part 21, the straight rectangular twisted tongue wire is forcibly bent into a U-shape. After the straight rectangular twisted tongue wire is bent into a U-shape, the U-shaped rectangular twisted tongue wire is clamped by the ridge forming structure assembly of the first clamping part 12 and the second clamping part 22. This allows several ridge structures that are adapted to the shape of the patient's oral cavity to be clamped onto the U-shaped rectangular twisted tongue wire, so that the rectangular twisted tongue wire retainer has a high degree of fit after installation. The bending instrument proposed can be modified or manufactured based on surgical clamps, similar to the operating habits of clinical dentists, making it convenient for doctors to operate and use. At the same time, it has low manufacturing cost and reliable effect, which can effectively solve the problem of the lack of simple, economical, reliable and easy-to-use lingual wire bending instruments in the existing technology.

[0036] Specifically, in this embodiment, both the first gripping part 11 and the second gripping part 21 are gripping rings;

[0037] The bending structure is a sliding forming ring 3 that is fitted onto the grip ring and slides freely on the grip ring;

[0038] The difference between the inner diameter of the sliding forming ring 3 and the cross-sectional size of the gripping ring is between 1 mm and 4 mm. In this embodiment, two sliding forming rings 3 are fitted on the same gripping ring. Technicians can set more or fewer sliding forming rings 3 on the same gripping ring as needed.

[0039] In this embodiment, the sliding forming ring 3 is made of metal to ensure sufficient strength, allowing it to easily bend and press the straight rectangular twisted tongue side wire into a U-shape.

[0040] Specifically, in this embodiment, the outer peripheral wall of the gripping ring is provided with a bending groove 111 for placing the rectangular twisted tongue wire. The bending groove 111 extends in a circular shape along the circumference of the gripping ring. By providing the bending groove 111, the rectangular twisted tongue wire will not move out of the bending groove 111 when it is subjected to the pressure of the sliding forming ring 3, thereby ensuring the stability of the forming shape of the rectangular twisted tongue wire.

[0041] Specifically, in this embodiment, the cross-sectional shape of the bending groove 111 is rectangular. Technicians can set the shape of the bending groove 111 to be semi-circular, U-shaped or other shapes as needed, which will not be elaborated here.

[0042] Specifically, in this embodiment, the inner peripheral wall of the sliding forming ring 3 is provided with a top pressure protrusion 31 that can be inserted into the bending groove 111, which can improve bending efficiency and reduce the number of times the sliding forming ring 3 is repeatedly pushed to slide.

[0043] Specifically, in this embodiment, the curved surface of the top pressing protrusion 31 facing the bending groove 111 is an arc-shaped curved surface to avoid damage to the rectangular twisted tongue side wire when pressing against it.

[0044] Specifically, in this embodiment, the protrusion forming structure assembly includes a protrusion forming groove 121 disposed on the first clamping part 12 and a protrusion forming protrusion 221 disposed on the second clamping part 22;

[0045] The shapes of the raised groove 121 and the raised protrusion 221 are adapted to each other and are respectively disposed on the opposite side of the first clamping part 12 and the second clamping part 22. In some embodiments, the positions of the raised groove 121 and the raised protrusion 221 can be interchanged.

[0046] Specifically, in this embodiment, the cross-sectional shape of the protrusion 221 and the groove 121 is semi-circular. Technicians can set the cross-sectional shape of the protrusion 221 and the groove 121 to other shapes such as U-shape and V-shape according to their needs.

[0047] In some embodiments, the technician can also set different shapes at different positions of the protrusion 221 and the groove 121, so that the clinical dentist can clamp out a more suitable and fitting protrusion structure according to the patient's protrusion shape. When the cross-sectional shape of the protrusion 221 and the groove 121 is of multiple shapes, the multiple shapes are distributed along the length direction of the first clamping part 12 and the second clamping part 22.

[0048] Specifically, in this embodiment, the maximum cross-sectional width of the protrusion 221 and the protrusion groove 121 is 1.5mm. Technicians can also set the size to other sizes such as 1mm and 2mm as needed, which will not be elaborated here.

[0049] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
