Description

Lock device of wire for orthodontics

The present invention relates to an orthodontic appliance, and more particularly, to a locking device for fixing an orthodontic wire, such as an arch wire, a paratal bar, to a support body fixed to abutment teeth.

Conventionally, in the case of orthodontic fixation using an orthodontic wire, especially an arch wire, a cylindrical tube is placed on the upper surface of the base plate on the surface of a band fitted to a posterior tooth made of abutment teeth. The arc wire is fixed by attaching the welded main body and inserting each of the pieces of the arch wire into the tube.

In addition, in order to prevent each piece of the archwire from being pulled out of the tube during use, a cutout groove is formed in the lower part of the front of the tube so that the spring piece is fitted and the spring piece is caught by each piece of the archwire. It was.

However, the conventional locking device has a problem in that the locking and releasing of the orthodontic wire is not smoothly performed according to the configuration thereof, and of course, the elasticity of the spring is poor and the arch wire falls out when repeatedly used. There was this.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a locking device having a strength that can be easily and reliably fixed to the support body, as well as to be repeatedly used.

In order to achieve the above object, the present invention is to orthodontic to fix the wire by inserting each of the two pieces of orthodontic wire in a pair of tubes installed side by side on the front of the support body fixed to the abutment, respectively In the device, the lower end of each tube of the support body is formed with a notch groove leading to the through hole, and the engaging groove is formed in the lower portion of the front side of each piece of the calibration wire, respectively, and between the left and right sides, The center portion of the locking springs, each of which formed the locking portions, were rotatably mounted, and when fitted, the respective locking portions of the locking springs were engaged with the locking grooves of each piece positioned in the cutout grooves of the tube, respectively. The structure is fixed to the support body.

In addition, the upper surface between the two tubes of the support body, slidably provided a locking plate extending to each of the locking portions to be inserted into the cutout groove in the left and right both ends, slidably inserted, both locking portions of the locking plate, Coupled to the engaging groove of each piece located in the notch groove, characterized in that for fixing the calibration wire to the support body.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

Example 1

In Figs. 1 to 4, 10 is an arch wire, each of which forms a rectangular square piece 11 near one end thereof in parallel with the arch wire at a predetermined interval and at the same time, respectively. One end of each side 11 of each of the engaging grooves 12 are formed.

13 is a locking spring formed of a resilient wire rod, and the center portion 14 is bent in a U shape, and at the same time, both ends thereof are slightly folded to form a catching portion 15.

16 is a support having elasticity placed between each of the two sides 11 of the arch wire 10, and supports the central portion 14 of the locking spring 13 to be rotatable, so that the locking spring 13 can be set up, both engaging portions 15 are To be coupled to each of the engaging groove 12.

20 is a support body, in which the tube 21 is integrally formed side by side so that it may have the same space | interval with each said piece 11, and the through-hole 23 of the rectangular shape was formed in the longitudinal direction inside each tube 21, respectively. Further, cutout holes 25 are formed in the transverse direction in the lower portion of the front side of each tube 21.

In the present embodiment, when both sides 11 of the archwire 10 are respectively fitted to the tube 21, the locking spring 13 is rotated first to disengage the engaging portions 15 from the engaging grooves 12.

Subsequently, after inserting both pieces 11 of the tube wire 10 into the tubes 21, the locking springs 13 are rotated to engage the locking portions 15 to the locking grooves 12. By fitting together, the archwire 10 is securely locked to the support body 20.

Subsequently, when removing each piece 11, when the locking spring 13 is turned to the pin tip and rotated in the opposite direction to the resilient direction, the locking portion 15 is separated from the locking groove 12, so that the arch wire 10 can be easily taken out of the support body 20.

Example 2

In the present embodiment, as shown in Figs. 5 to 8, the arch wire 10 forms the engaging grooves 12 in each of the front end portions of the respective pieces 11, respectively.

Further, the support main body 30 is provided with the engaging holes 33 in the lateral direction reaching up to the through hole 32 in the lower portion of each tube 31, respectively.

40 is a locking plate attached to the upper surface of the support body 30 between the tube 31, consisting of a slide portion 41 bent in a 'U' shape, and the engaging portions 42, 43 extending the upper end portion to the left and right sides.

The slide part 41 is supported by the support piece 51 which protrudes in the front side center part of the press plate 50 formed between the tube 31 of the said support body 30, and is hold | maintained so that the tube can be rocked in the left-right direction.

The locking portions 42 and 43 are fitted into the locking holes 33 of the tube, respectively, and form a notch groove 44 having a width slightly larger than the diameter of the through hole 32 of the tube.

Subsequently, when the locking plate 41 is moved until the left standing portion 45 is in contact with the outer surface of the left tube 31, the outer ends of the engaging portions 42 and 43 are respectively positioned in the through hole 32, and the right side thereof When the standing portion 46 is moved until it comes in contact with the outer surface of the right tube 31, the outer end of the left locking portion 42 is released from the through hole 32 of the right tube. Subsequently, the outer end of the right locking portion 43 is also separated from the through hole 32 of the right tube, so that the cutout groove 44 can be positioned in the through hole 32.

Subsequently, in this embodiment, after inserting each of the two pieces 11 of the arch wire 10 into each of the tubes 31, the locking plate 41 is slid, and when the left standing portion 45 is in contact with the outer surface of the left tube 31, both the latches The outer ends of the sections 42 and 43 are simultaneously engaged with the locking grooves 12 of the arch wire 10, so that the arch wire 10 is securely coupled to the support body 30.

In addition, when removing each piece 11, when the locking plate 41 is slid to the right, and the right standing part 46 contacts the outer surface of the right tube 31, the outer edges of both locking parts 42 and 43 will become the locking grooves 12 of the arch wire 10. By simultaneously deviating from, the archwire 10 can be easily removed from the support body 30.

Although each of the above embodiments has been described as an example of using an arch wire as a specific orthodontic wire, it is possible to use this locking device even when using other orthodontic wire such as a paratal bar.

According to the present invention, the orthodontic wires such as arch wires can be reliably fixed to the support body fixed to the abutment teeth, and can be easily removed. It has an effect that can be carried out.

In addition, since it has sufficient strength to withstand repeated use, the archwire does not come off during the calibration period, which has the advantage that the orthodontic treatment can be performed with confidence.
