SUMMERY OF THE UTILITY MODEL
To the deficiency that prior art exists, the utility model aims to provide a novel place ahead draw gear wears comfortablely, and can be used for the lower jaw tooth.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a novel place ahead traction device, is including being used for fixing the fixed bolster on one side tooth, fixing the cover of pulling on the opposite side tooth and being used for connecting the fixed bolster and pull the elastic component of cover, is provided with first portion of colluding on the fixed bolster, pulls to sheathe in and is provided with the second portion of colluding, and first portion of colluding and the second portion of colluding pass through the elastic component and connect, and when pulling, the first portion of colluding stretches out the distance of mouth and is greater than the second portion of colluding and stretches out the distance of mouth.
As a further improvement of the utility model, the fixing bracket comprises a circular arc base rod and a plurality of fixing parts fixed on the base rod, and the base rod and the fixing parts form a fixing structure buckled on the teeth.
As a further improvement, the base rod is provided with a U-shaped adjusting curve, the adjusting curve is fixed with an installation rod, and the first hook part is fixed on the installation rod.
As a further improvement of the utility model, the elastic piece is a rubber band.
As a further improvement of the utility model, the fixed support is connected with a cushion pad.
As the utility model discloses a further improvement, it has a plurality ofly to pull the cover, and a plurality of cover that pull divide into two sets ofly, and every group pulls the cover and all connects with the alloy silk, and the second colludes the portion and fixes on the alloy silk, and first portion of colluding is provided with two, and two first portion symmetries of colluding set up on the fixed bolster.
The beneficial effects of the utility model, through installing support, traction sleeve on tooth and gum, the tensile tooth of cooperation elastic component does not have the damage to human forehead and lower jaw, and wears more pleasing to the eye, also can avoid traditional tractor to make the problem of mandible down-spin.
Drawings
Fig. 1 is a structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to embodiments shown in the drawings.
Referring to fig. 1, the novel front traction device of the present embodiment includes a fixing bracket 1 for fixing on one side of teeth, a traction sleeve 2 for fixing on the other side of teeth, and an elastic member 3 for connecting the fixing bracket 1 and the traction sleeve 2, wherein a first hook portion 4 is provided on the fixing bracket 1, a second hook portion 5 is provided on the traction sleeve 2, the first hook portion 4 and the second hook portion 5 are connected through the elastic member 3, and when traction is performed, the distance that the first hook portion 4 extends out of the mouth is greater than the distance that the second hook portion 5 extends out of the mouth.
When the treatment, medical personnel fix fixed bolster 1 on patient upside or the tooth of downside, then fix traction sleeve 2 on the tooth of opposite side again, and fixed completion back is connected first portion 4 and the second portion 5 of colluding with elastic component 3, outwards pulls traction sleeve 2 through elasticity to outwards pull the tooth. The elastic part 3 can adopt a rubber band for correction, thereby achieving better traction effect. Before the fixing support 1 is installed, cushion pads can be installed on teeth and gum of a patient, so that damage to the teeth caused by the fixing support 1 during correction is reduced, and the cushion pads can be made of medical silica gel and other materials. The utility model discloses a installing support, traction cover 2 on tooth and gum, the tensile tooth of cooperation elastic component 3 do not have the damage to the forehead and the lower jaw of human body, and wear more pleasing to the eye, also can avoid traditional tractor to make the problem of mandible down-spin.
As a modified embodiment, the fixing bracket 1 comprises a circular arc-shaped base rod 11 and a plurality of fixing parts 12 fixed on the base rod 11, and the base rod 11 and the fixing parts 12 form a fixing structure buckled on teeth.
The fixing parts 12 are connected through the base rod 11, so that the stress of each fixing part 12 is concentrated, the contact area of the fixing bracket 1 with teeth and gums can be increased, the fixing bracket 1 is more firmly arranged on the teeth and gums, and larger and more stable traction force is provided.
As a modified specific embodiment, a U-shaped adjusting curve 13 is arranged on the base rod 11, a mounting rod 14 is fixed on the adjusting curve 13, and the first hook part 4 is fixed on the mounting rod 14.
When the treatment, medical personnel can be more the angle that patient's tooth grows, and the crooked 13 of compression or tensile adjustment to make the angle adaptation patient's tooth of first portion of colluding 4 the growth angle, make the traction force of first portion of colluding 4 reach better angle, and then reach better correction effect. The U-shaped adjusting bend 13 is convenient to adjust in the using process, the influence on the overall structure of the fixing support 1 is small, and the influence on the installation of the fixing support 1 caused by adjustment is avoided.
As a modified specific embodiment, a cushion pad is connected to the fixing bracket 1.
As a modified specific implementation mode, the plurality of traction sleeves 2 are divided into two groups, each group of traction sleeves 2 is connected by an alloy wire 6, the second hook parts 5 are fixed on the alloy wire 6, the number of the first hook parts 4 is two, and the two first hook parts 4 are symmetrically arranged on the fixed support 1.
Through a plurality of settings that pull cover 2, pull tooth from a plurality of positions, reuse alloy silk 6 will pull cover 2 and fall into two sets ofly, collude portion 4 and second through two first colluding and draw 5, avoid too much colluding the problem that the portion installed easy damaged oral cavity skin on the tooth, and will pull the back that cover 2 couples together, pull the power between cover 2 and just can concentrate on 1 of redispersion to make the tooth have more comfortable atress.
Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
