Description

A kind of correction draws augmentor automatically

Technical field

The utility model relates to medical apparatus technical fields more particularly to a kind of correction to draw augmentor automatically.

Background technique

The tooth as caused by innate factor or acquired disposition, jawbone, the lopsided of cranium face usually need to do orthodontic treatment.Closely A little years anchorage clinically being introduced extensively in orthodontic field and plants nail technology, plantation nail is by surgical operation by alloy kind It plants in nail implantation alveolar bone, as the fixed point for applying Orthodontic force, rescuing doctor can be more directly and effectively to target tooth Apply active force.Since anchorage plantation nail is usually placed in the alveolar bone of upper lower jaw cheek side, in this way due to the kind as fixed point The stress point for planting nail and target corona is not at same level, the side that gum is more biased to than leading to common draw hook in position To tooth will receive apparent gum to component, which will certainly generate the side effect of inclination movement, generate not to orthodontic treatment Good influence；It uses rubber band or spring as traction power between plantation nail and draw hook simultaneously, gradually realizes target tooth It rescues, since tractive force remains unchanged, tooth continues single load bearing, can generate compressing to gum and cause discomfort.

Utility model content

Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of correction proposed is led automatically Draw augmentor.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of correction draws augmentor automatically, bracket, draw hook, arch wire and plantation including being adhered to crown surfaces Nail, the arch wire extend transversely through bracket and connect several brackets being located on different coronas, are equipped in the bracket perpendicular To jack, the draw hook bottom insertion jack in is fixedly connected with bracket, the draw hook and plantation follow closely between pass through Tension spring is connected, and is equipped with push rod in the jack of the bracket between draw hook and plantation nail, the bottom of the push rod is connected with Facing, the upper socket of the push rod have locating piece, are equipped with lateral perforation in the locating piece, the tension spring is worn across this Hole.

Preferably, the draw hook and push rod are all made of stainless steel material and are made.

Preferably, the locating piece can be slided up and down along push rod, and be fastenedly connected by lock-screw and push rod.

Preferably, it is straightway that the tension spring, which is located at one end in locating piece, and this section passes through the punched card in locating piece It connects between locating piece and push rod.

Preferably, the facing is made of silica gel material.

In the utility model, push rod and locating piece are set by using at the middle part of tension spring, the position of spring or more can be made It is mobile, so that the stress almost horizontal of target tooth, avoids tooth from will receive apparent gum and generates inclination to component and move Dynamic side effect improves the effect of orthodontic therapy, while push rod can be moved up and down when upper lower jaw is engaged and is opened, so that drawing The pulling force of spring back and forth increases and decreases, and realizes automatic driving-force adding, and by the size of the extent control of occlusion reinforcing, is conducive to gum to rescuing The adaptation of pulling force, that accelerates tooth rescues process.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1 bracket, 2 draw hooks, 3 arch wires, 4 kinds of plant nails, 5 tension springs, 6 push rods, 7 locating pieces, 8 facings, 9 coronas.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1, a kind of correction draws augmentor automatically, including be adhered to the bracket 1 on 9 surface of corona, draw hook 2, Arch wire 3 and plantation nail 4, arch wire 3 extends transversely through bracket 1 and connects several brackets 1 being located on different coronas 9, bracket 1 It is interior to be equipped with vertical jack, it is fixedly connected in the bottom insertion jack of draw hook 2 with bracket 1, between draw hook 2 and plantation nail 4 It is connected by tension spring 5, is equipped with push rod 6 in the jack of the bracket 1 between draw hook 2 and plantation nail 4, draw hook 2 and pushes away Bar 6 is all made of stainless steel material and is made, and guarantee has sufficient intensity, and apparent shape does not occur under the Orthodontic traction power of tension spring 5 Become, the bottom of push rod 6 is connected with facing 8, and facing 8 is made of silica gel material, and the upper socket of push rod 6 has locating piece 7, positioning Block 7 can be slided up and down along push rod 6, and be fastenedly connected by lock-screw with push rod 6, and lateral perforation is equipped in locating piece 7, be drawn Spring 5 passes through the perforation, and it is straightway that tension spring 5, which is located at one end in locating piece 7, and this section passes through the perforation clamping in locating piece 7 Between locating piece 7 and push rod 6.

Working principle: when the utility model is used, unscrewing the lock-screw on locating piece 7, make locating piece 7 in push rod 6 On be moved to suitable position, then screwing lock-screw is fixed on locating piece 7 on push rod 6, while being interspersed in locating piece 7 The straightway of tension spring 5 is also locked, to realize the adjustment of 5 direction of pull of tension spring, by maxillomandibular interlocking, under Jaw applies pressure to facing 8, and facing 8 pushes push rod 6 to move up, then tension spring 5 is stretched, to increase tractive force automatically, leads to The size that control facing 8 is snapped into effect extruding degree is crossed, the increased size of tractive force is controlled.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
