Abstract

The utility model relates to a flexible wing bracket with a cover. The flexible wing bracket with a cover comprises the fixed wing which is integrally provided with a bracket seat and a moveable wing which is arranged on the bracket seat slipperily and pivotally. A channel the space of which can be adjusted is formed between the fixed wing and the moveable wing, wherein, at least one wing extends to be provided with a baffle cover towards to the channel. An arch wire can be limited in the channel forcibly through the baffle cover, thereby effectively preventing the arch wire from arching so as to influence the rectifying strength. The utility model has a more reasonable structural design not only with a single moveable wing and the space of the channel can be adjusted properly, but also with a baffle cover through which the arch wire can be limited in the channel forcibly, thereby ensuring an excellent rectifying strength and avoiding the elastic influence of a rubber ring. When in practical operation, the rubber ring can be tied through traditional operation ways, or can be tied in the channel firstly before the arch wire is arranged in, thereby ensuring more convenient operation and easier handling.

Description

Support slot with movable wings with cover

Technical field:

This utility model belongs to the medical apparatus field, particularly a kind of improvement of Support slot with movable wings of straightening of teeth.

Background technology:

Existing orthodontics bracket structure is the bracket seat that a bottom surface and the flank of tooth match, and the surface of bracket seat offers flat recess, and the bracket seating face that flat recess separates forms the protruding wing naturally, and the outside of the protruding wing offers the ligation groove, is convenient to ligation.During use, the bracket bottom surface is bonded on the tooth, one of each facing bonding is pacified an arch wire in the flat recess then, uses the structure of each malposed tooth of elastic force traction correcting of arch wire.The arrangement of malposed tooth is different, and is also random, often is difficult to arch wire is pacified in the bracket flat recess on each facing.Two Support slot with movable wings that this claimant formerly designs, the folding foot of the first two protruding wings is folded on the bracket seat locatees, forming the two protruding wings can relatively move, and realizes the broad-adjustable purpose of flat recess, be convenient to arch wire pacify into; Two to be protruding wings become the fixed protruding wing with bracket seat disjunctor for it, and another becomes the moving protruding wing of dynamic fit.Utilization clinically facts have proved that the latter is science more, decides the wing as localized benchmark, and utilizes the moving wing to regulate the spacing of flat recess, and the ligation operation is also simple.But all need during ligation rubber ring is striden across arch wire, with this arch wire is limited in the groove, because rubber ring has elasticity, arch wire tends to arch upward, and is difficult to docile in groove.

Summary of the invention:

The purpose of this utility model be the design a kind of can be with the with cover Support slot with movable wings of arch wire hard limit in groove.

Technical solutions of the utility model are achieved in that a kind of Support slot with movable wings with cover, comprise that a disjunctor has the decide wing and slide pivot of bracket seat to be located at the moving wing on the bracket seat, decide the wing and the moving adjustable conduit of interplane formation one spacing, wherein at least one wing is extended with a door towards conduit one side, utilize the door hardening capacity that arch wire is limited in the groove, effectively avoid it to arch upward, and influence corrective force.

Describedly decide the wing and the moving wing all is extended with a door towards conduit one side, two relative door mutual dislocation.This kind structure, even conduit has been regulated broad, two staggered doors still can limit it in groove with arch wire, and unaffected.

This utility model more reasonable structural design had both had movable single-blade, and the conduit spacing can suitably be regulated, and door was arranged deciding the wing one side connecting rod again, can guarantee to have good corrective force with the arch wire hard limit in groove, and was not subjected to that rubber ring is elastic to be influenced; During clinical manipulation, the ligation of rubber ring can be adopted the traditional operation method, arch wire is inserted in the conduit ligation then earlier; The rubber ring ligation also can be about to earlier in groove, when packing arch wire into, utilize arch wire to back down the moving wing, arch wire be slipped in the conduit get final product, operate more convenient and be easy to and grasp.

The specific embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, Support slot with movable wings, comprise that a disjunctor has the decide wing 11 and slide pivot of bracket seat 1 to be located at the moving wing 2 on the bracket seat, bracket seat 1 and the moving wing 2 are made by steel material, decide the wing 11 middle parts and be provided with the chute 12 that can supply the moving wing 2 pins 21 to insert, conduit 5 spacings that scalable was moved the wing 2 and decided 11 formation of the wing when both cooperated, more helpful to the rectification initial stage.The moving wing 2 and decide the wing 11 opposing sides and have ligation groove hook 3 makes things convenient for the location of being inserted in of ligation rubber ring 7.Decide the wing 11 and the moving wing 2 among the figure and all be extended with relative door 4 mutual dislocation of a door 4, two,, also arch wire 6 can be limited in wherein even conduit 5 is when the design maximum width like this towards conduit 5 one sides.

With reference to Fig. 2, bracket side view, arch wire 6 can be limited among the conduit 5 after going into groove, are subjected to door 4 effects, can not arch upward, and guarantee the corrective force that vertical flank of tooth direction agree have; And the corrective force that is parallel to flank of tooth direction is promptly provided by the rubber ring 7 of ligation, when the rectification initial stage, the adjacent teeth distortion is bigger, arch wire is difficult to remain parallel to conduit 5, and exist certain dislocation, this moment certainly will will move the wing and slightly back down, also be that conduit 5 broadens, and the elastic force of rubber ring 7 remains and conduit 5 diminished and arch wire 6 is guided to the trend parallel with conduit 5, produces certain corrective force.Among this figure, rubber ring 7 can be gone into ligation in the ligation groove 3, also can be as the ligation of dotted line place.

With reference to Fig. 4, what provide in legend all is extended with the door 4 in fixed, moving wing both sides, also can only be extended with door 4 in a side of deciding one of the wing 11 or moving wing 2 wing, it can play the effect of restriction arch wire 6 equally, especially be extended with door 4 for good to decide the wing 11, this moment, the moving wing 2 one sides were flat mouthful shape, when arch wire 6 embeds and takes out, last example is convenient, can conflict by arch wire and move the wing 2, overcome the elastic force of rubber ring 7, will move the wing 2 slips and open, and utilizing the gap of 2 on door 4 and the moving wing, arch wire 6 can be taken advantage of a situation and be slipped into and skid off.
