Technical Field
[0001] This utility model relates to the technical field of archwire connection devices, specifically an orthodontic archwire connection device. Background Technology
[0002] Orthodontic archwires are metal wires used to connect the framework of teeth. By applying appropriate force, they guide the movement of teeth to correct occlusion and malocclusion.
[0003] However, existing bowwire connection devices have the following drawbacks:
[0004] (1) The existing connection device connects the two sections of archwire by welding, which is more troublesome in clinical operation. In addition, the existing archwire cannot be directly used to form a square and round wire in clinical practice. It is necessary to recast an integrated square and round wire.
[0005] (2) Existing connection devices cannot connect broken wires on orthodontic appliances, and often need to be returned to the factory for repair, which prolongs the treatment time.
[0006] In view of the above, an orthodontic archwire connection device is proposed to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this invention is to provide an orthodontic archwire connection device to solve the problems mentioned in the background art, which are that the existing connection devices connect two archwires by welding, which is cumbersome in clinical operation, and cannot directly use the existing archwires to form a square-round wire in clinical practice. Instead, an integrated square-round wire needs to be recast. The connection device cannot connect broken wires on orthodontic appliances, which often requires returning to the factory for repair, thus prolonging the treatment time.
[0008] To achieve the above objectives, this utility model provides the following technical solution: an orthodontic archwire connection device, comprising a connecting tube, an upper clamp head provided at the top end of the connecting tube, pressure heads provided on both sides of the bottom end of the upper clamp head, a lower clamp head provided at the bottom end of the connecting tube, a slot one provided at one end of the connecting tube, a slot two provided at the other end of the connecting tube, a positioning groove one provided on one side of the inner wall of the slot one, a positioning groove two provided on one side of the inner wall of the slot two, a retaining groove provided in the middle of the bottom end of the connecting tube, and a retaining strip provided in the middle of the top end of the lower clamp head.
[0009] When using an orthodontic archwire connection device based on this technical solution, two archwires are connected by mechanical clamping. The clinical operation is convenient and simple. In clinical practice, existing archwires can be directly used to form a square-round wire without the need to recast an integrated square-round wire.
[0010] In a preferred embodiment of this invention, the locking strip engages with the inner wall of the slot. The insertion of the locking strip into the slot prevents the connecting tube from shifting left or right, or up or down.
[0011] In a preferred embodiment of this invention, the longitudinal sections of both slot one and positioning groove one are square, while the longitudinal sections of both slot two and positioning groove two are circular. The use of square and circular slots respectively allows the two sections of bowwire to be combined to form a square-round bowwire.
[0012] In a preferred embodiment of this invention, both the longitudinal sections of slot one and positioning groove one are square, as are the longitudinal sections of slot two and positioning groove two. The square shape of both slots allows for the connection of broken square steel wires.
[0013] In a preferred embodiment of this invention, both the longitudinal sections of slot one and positioning groove one are circular, as are the longitudinal sections of slot two and positioning groove two. The circular design of both slots allows for the connection of broken circular steel wires.
[0014] In a preferred embodiment of this invention, a connecting seat is fixedly connected to the center of the front of the lower clamp head, a spring is fixedly connected to the bottom end of the inner wall of the connecting seat, and a stop finger is fixedly connected to the top end of the spring. The stop finger, when ejected, further enhances the limiting effect on the connecting tube.
[0015] In a preferred embodiment of this invention, sliders are provided on both sides of the bottom of the stop finger, and sliding grooves are provided on both sides of the inner wall of the connecting seat. The sliders and sliding grooves limit and guide the movement of the stop finger.
[0016] In a preferred embodiment of this invention, the slider is slidably connected to the inner wall of the groove. The stop finger can slide up and down on the inner wall of the connecting seat.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This connecting device connects two sections of archwire by mechanical clamping, which is convenient and simple to operate in clinical practice. In clinical practice, it can directly use existing archwires to form square and round wires without the need to recast an integrated square and round wire.
[0019] 2. This connecting device can connect broken wires on orthodontic appliances, avoiding the need to return them to the factory for repair and prolonging the treatment time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figure 1-4 This utility model provides an orthodontic archwire connection device, including a connecting tube 1. The top end of the connecting tube 1 is provided with an upper clamp head 6. Both sides of the bottom end of the upper clamp head 6 are provided with pressure heads 7 for applying pressure. The bottom end of the connecting tube 1 is provided with a lower clamp head 8. One end of the connecting tube 1 is provided with a slot 1 2, and the other end of the connecting tube 1 is provided with a slot 2 4. One side of the inner wall of slot 1 2 is provided with a positioning groove 3, and one side of the inner wall of slot 2 4 is provided with a positioning groove 2 5, so that the insertion of the archwire is more stable. A retaining groove 10 is provided in the middle of the bottom end of the connecting tube 1, and a retaining strip 9 is provided in the middle of the top end of the lower clamp head 8.
[0028] When in use, place the connecting tube 1 between the upper jaw 6 and the lower jaw 8 of the pliers, insert the two sections of bow wire into the slots at both ends of the connecting tube 1 respectively, and insert the ends into the positioning grooves to improve the stability. Then, apply pressure with the pliers, and with the pressure head 7 at the upper jaw 6, deform the top two sides of the connecting tube 1, and fix the two sections of bow wire by mechanical clamping.
[0029] The locking strip 9 engages with the inner wall of the slot 10, which serves as a limiting function. The longitudinal section of slot 1 2 and the longitudinal section of positioning slot 1 3 are both square, while the longitudinal section of slot 2 4 and the longitudinal section of positioning slot 2 5 are both circular.
[0030] When in use, align the locking bar 9 of the lower clamp head 8 and insert it into the locking groove 10 at the bottom of the connecting tube 1 to limit the movement and prevent deviation. One of the slots in the connecting tube 1 is a square slot and the other is a round slot, which allows the existing bow wire to be directly matched with a square or round wire, making it convenient to use.
[0031] A connecting seat 11 is fixedly connected to the center of the front of the lower clamp head 8. A spring 12 is fixedly connected to the bottom of the inner wall of the connecting seat 11.

Then, by applying pressure with the pliers and cooperating with the pressure head 7 at the upper jaw 6, the top two sides of the connecting tube 1 are deformed. The two archwires are fixed by mechanical clamping. One slot of the connecting tube 1 is a square slot and the other is a round slot, which allows the existing archwires to be directly matched to form a square and round wire, which is convenient to use. The front part of the archwire is a square wire with an arc shape, and the two rear parts are round wires.
