Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of orthodontics, and particularly relates to a lingual personalized free hook clamping forceps. BACKGROUND

[0002] With the popularity and promotion of orthodontics, orthodontic treatment is increasingly accepted by the public. In orthodontic treatment, tooth extraction treatment is very common. One of the indispensable steps in tooth extraction treatment is to close the extraction space. In the process of tooth movement, if the traction tool is directly hung on the bracket for traction, due to the difference in the direction and size of the force on the tooth, the tooth is easy to lose the axial inclination, torque and torsion.

[0003] Therefore, more and more doctors use the combination of long free hooks and anchorage nails for retraction when closing the space. However, due to the small gap of the personalized lingual bracket, the straight long free hook often does not have enough space for fixation, clamping and welding. Therefore, in the personalized lingual bracket, a personalized long free hook is used for fixation, clamping and welding. The personalized long free hook is different from the straight free hook in shape, so there is no suitable existing tool for clamping. CONTENT OF THE UTILITY MODEL

[0029] The content of the present disclosure will be further described in detail in combination with the drawings and specific embodiments.

[0030] ​Currently, clamping pliers are generally used for clamping straight free hooks. The shape of the clamping seat for tongue-side customized free hooks is different from that of straight free hooks, and clamping pliers of related technologies are not compatible with tongue-side customized free hooks.

[0031] To address the inconvenience of clamping with personalized free hooks on the tongue side in related technologies, this disclosure provides a personalized free hook clamping pliers on the tongue side. The personalized free hook clamping pliers on the tongue side of this disclosure are described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the tongue-side personalized free hook clamping pliers according to an embodiment of the present disclosure; Figure 2 This is a schematic diagram of the jaw portion of the tongue-side personalized free hook clamping pliers according to an embodiment of the present disclosure; Figure 3 This is a schematic diagram of a tongue-side personalized free hook clamping pliers according to an embodiment of this disclosure; Figure 4 This is an exploded view of the tongue-side personalized free hook clamping pliers according to an embodiment of the present disclosure; Figure 5 This is a three-dimensional side view of the tongue-side personalized free hook clamping pliers according to an embodiment of the present disclosure; Figure 6 for Figure 5 A partially enlarged structural diagram. Figure 7 This is a side plan view of the tongue-side personalized free hook clamping pliers according to an embodiment of this disclosure. (Refer to...) Figures 1 to 7 As shown, this embodiment of the present disclosure provides a tongue-side personalized free hook clamping pliers 10, including a first clamping body 100 and a second clamping body 200. The first clamping body 100 includes a first clamping handle 110, a first clamping head 120, and a first pivot portion 150 located between the first clamping handle 110 and the first clamping head 120. The second clamping body 200 includes a second clamping handle 210, a second clamping head 220, and a second pivot portion 230 located between the second clamping handle 210 and the second clamping head 220. The first pivot portion 150 and the second pivot portion 230 intersect and are pivotally connected via a connector 300. The first clamping head 120 and the second clamping head 220 have a closed state in contact with each other and an open state in separation. A compression groove 130 is provided on the side of the first clamping head 120 facing the second clamping head 220, and the compression groove 130 is adapted to the tongue-side personalized free hook 20.

[0033] For example, an operator can switch the first jaw 120 and the second jaw 220 between a closed state and an open state by manipulating the first jaw handle 110 and the second jaw handle 210. The first jaw handle 110 and the second jaw handle 210 can be generally arc-shaped. The first jaw handle 110 and the second jaw handle 210 can be provided with anti-slip structures to prevent the operator from slipping when holding the jaws. For example, the first jaw handle 110 and the second jaw handle 120 can be fitted with a rubber structure, or the first jaw handle 110 and the second jaw handle 120 can be provided with multiple anti-slip protrusions.

[0034] It should be noted that the extrusion groove 130 is used to clamp the lingual personalized free hook 20, and the extrusion groove 130 is matched with the lingual personalized free hook. It can be understood that the extrusion groove 130 is matched with the shape of the clamping seat of the lingual personalized free hook. For example, the clamping seat of the lingual personalized free hook is suitable for fixing the angle position with the adjacent arch wire, and the shape of the clamping seat is arranged at an angle. The extrusion groove 130 is matched and clamped according to the shape of the clamping seat.

[0035] The lingual personalized free hook clamping forceps of the embodiment of the present disclosure is provided with a first forceps body 100 and a second forceps body 200 which are arranged in a cross manner. The first forceps body 100 comprises a first forceps handle 110, a first forceps head 120 and a first pivot joint 150. The second forceps body 200 comprises a second forceps handle 210, a second forceps head 220 and a second pivot joint 230. The two ends of the first pivot joint 150 are connected with the first forceps handle 110 and the first forceps head 120 respectively. The two ends of the second pivot joint 230 are connected with the second forceps handle 210 and the second forceps head 220 respectively. The first pivot joint 150 and the second pivot joint 230 are crossed and connected with each other through a connecting piece 300 in a pivotable manner. The side of the first forceps head 120 facing the second forceps head 220 is provided with an extrusion groove 130 which is matched with the lingual personalized free hook 20. By controlling the first forceps head 120 and the second forceps head 220 from the open state to the closed state, the first forceps head 120 and the second forceps head 220 gradually approach each other. Thus, the second forceps head 220 can clamp the lingual personalized free hook 20 matched with the extrusion groove 130 with the arch wire, so as to fix the lingual personalized free hook on the arch wire, thereby realizing the clamping and fixing of the lingual personalized free hook.

[0036] In an embodiment, the extrusion groove 130 comprises a first groove wall 131 and a second groove wall 132. The extension line of the first groove wall 131 and the extension line of the second groove wall 132 are arranged at an angle. The angle between the extension line of the first groove wall 131 and the extension line of the second groove wall 132 ranges from 90° to 180°.
