Abstract
The present invention " establishes the arch former of depression bar with end " and relates to a kind of type medical instrument for dental use, is solve the troublesome poeration existed in mouth cavity orthodontic clinical arch wire forming process, wayward, the time long and easy problem such as wound finger and inventing.This product connects two handles and finger ring and the depression bar tangent with moulding outer surface circumference establishing on fluted cylindric moulding, after arch wire enters groove, can one hold fixed handle, and rotate finger ring with two of another hands fingers, depression bar drives arch wire to be rotated into groove to both sides, gets final product once-through operation archwise; Not only ensure that dental arch filament form is symmetrical, and simplify forming step.Save the operating time of doctor, require to reduce to doctor's operation skill; Avoid doctor's finger injuries, time saving and energy saving.Can be widely used in mouth cavity orthodontic clinical in carry out arch wire molding making.
Description
Technical field
The present invention relates to a kind of type medical instrument for dental use, be specifically related to a kind of arch former being designed with two depression bars with end.
Background technology
Along with the development of mouth cavity orthodontic medical science, the application of arch wire in correction is clinical is a requisite vitals.In correction clinical medicine, first need bending forming arch wire being carried out to definite shape before rectification, and just must use special arch wire former when bending shaping.At present, the arch wire former structure used clinically is: overall in dumbbell shaped, middle cylindric moulding connects the handle at two ends by axle, only on a handle, establish depression bar, arch wire is placed on size with it and matches in the groove of moulding by clinician, then push down arch wire one end with left hand thumb, drive depression bar to rotate on moulding surface by turning handle, arch wire is bent right and left and is shaped with applicable dental arch shape.
But there is following drawback in this arch former: 1, need molding at twice, in the process arch wire easily depart from groove produce left-right asymmetry; 2, need in use to compress arch wire with finger, troublesome poeration, wayward, the time has been grown and has easily made finger surface injured.
Therefore design new arch former, to raising arch wire brake forming efficiency, precision, and alleviate working doctor burden and be significant.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes deficiency of the prior art, provides a kind of arch former establishing two depression bars with end.
In order to solve the problems of the technologies described above, the present invention adopts following solution:
Thering is provided a kind of and establish the arch former of two depression bars with end, comprise columned moulding, being provided with the groove for placing arch wire at moulding outer surface along the circumferencial direction in its cross section; Moulding is fixedly connected with first handle, and moulding is sheathed on axle and along axial displacement and can pivots, and the other end of axle is fixedly attached to second handle; Pivot bush unit rotating ring on axle between moulding and second handle, is fixedly installed a finger ring respectively at second handle and the adjacent both sides of rotating ring; Inside second handle, be fixedly installed a depression bar respectively with rotating ring outer surface, two depression bars are all parallel with axle, and the lower surface of depression bar is cambered surface, and tangent with moulding outer surface circumference.
As one invention, described two depression bars lean on the end of moulding side to be perpendicular to and axially align.
As one invention, the depression bar on described second handle and rotating ring aligns vertically with respective finger ring fixed position.
As one invention, described first handle and moulding establish through hole and establish counterbore in the outer end of first handle, and axle is connected with steady pin with after the through hole of first handle through moulding.
As one invention, described axle is embedded in steady pin or steady pin is embedded in axle, and both are interference fit.
Compared with prior art, the invention has the beneficial effects as follows:
1, compared with existing arch former, this product is provided with two depression bars in same one end, can one hold fixed handle, and with two of another hands finger rotate finger rings, can once-through operation be shaped; Not only ensure that dental arch filament form is symmetrical, and simplify forming step.
2, save the operating time of doctor, require to reduce to doctor's operation skill; Avoid doctor's finger injuries, time saving and energy saving.

Fig. 2 is the schematic diagram of product open mode of the present invention.
Reference numeral in figure: moulding 1, groove 2, first handle 3, axle 4, second handle 5, rotating ring 6, finger ring 7, finger ring 8, depression bar 9, depression bar 10.
Detailed description of the invention
Further illustrate content of the present invention below in conjunction with accompanying drawing, but should not be construed as product of the present invention want protection domain to be only limitted to this.
As shown in Figure 1, the arch former of two depression bars is established to comprise columned moulding 1 with end, the groove 2 for placing arch wire is provided with along the circumferencial direction in its cross section at moulding 1 outer surface, the width of groove 2 is 0.016 ", 0.017 ", 0.018 ", 0.019 ", 0.022 " equidimension (English unit), the degree of depth is 0.025 " (English unit); Moulding 1 and first handle 3 integrated connection, moulding 1 is sheathed on axle 4, and fixes with axle 4; The other end of axle 4 is provided with the second handle 5 and 6 that can rotate on axle 4, can rotate between second handle 5 and 6 simultaneously; Second handle 5 and 6 secures respectively finger ring 7,8, finger ring 7,8 can insert thumb and forefinger respectively, by separately and merge two fingers and reach depression bar 9,10 and against moulding 1 on axle 4 and rotate.
First handle 3 and moulding 1 establish through hole, and counterbore is established in the outer end of first handle 3, and axle 4 is connected with 3 through the through holes of moulding 1 inserting first handles 3 after second handle 5 and 6.Axle 4 embeds both first handles 3 for interference fit, and in second handle 5 and 6 is half heavy through hole, and adopts jump ring mode to fix between axle 4.
Depression bar in the present embodiment 9,10, in cylindric, also can be processed into that other is shaft-like.As long as guarantee that lower surface is cambered surface, and tangent with moulding 1 outer surface circumference.The length of depression bar 9,10 differs, and wherein depression bar 9 is a little longer.But by moulding 1 side, the end of two depression bars is perpendicular to axially aligns.For the ease of putting forth effort, the depression bar on second handle 5 and rotating ring 6 aligns vertically with respective finger ring fixed position, and namely depression bar 9 aligns with finger ring 7, and depression bar 10 aligns with finger ring 8.
Because moulding 1 is overall with first handle and second handle 5 is movable with 6 mutually countershaft 4, therefore under the drive of finger ring 7,8, second handle 5 and 6 can rotate or displacement relative to moulding 1, and then realizes depression bar 9,10 in the displacement of moulding 1 outer surface or rotation.
The using method of this product:
Get the square arch wire of certain length, pull-out second handle 5 and 6, is placed into size with it by the stage casing of square arch wire and matches in groove 2.One holds first handle 3, and the centre of the palm of another hands props up second handle 5 end, and by two of this hands fingers through finger ring 7,8.Drawing finger ring 7,8 in makes two depression bars 9,10 draw close and be moved to the surface of moulding 1, the side's of pushing down arch wire; Two fingers expand outwardly and finger ring 7,8 are separated, then drive two depression bars 9,10 to rotate towards rightabout along moulding 1 outer surface, thus the side's of making arch wire completes and mouldingly obtains required dental arch filament.
