Abstract

The invention relates to a dentistry medical device, and provides an arch wire forming machine with pressure rods arranged at two ends. The forming machine comprises a cylindric molding part located in the middle part of a shaft. Grooves used for placing arc wires are arranged in the external surface of the molding part along the peripheral direction of the cross section. Handles are arranged at two sides of the shaft. A pressure rod is arranged at the inner side of one handle. The two handles are both sleeved on the shaft and can move along the shaft and rotate around the shaft. A pressure rod is also arranged at the inner side of the other handle. The two pressure rods are both parallel to the shaft, and the lower surfaces are cambered surfaces, and are tangent to the periphery of the external surface of the molding part. When the provided arch wire forming machine is compared to existing arch wire forming machines, the handles arranged at two ends of the arch wire forming machine are equipped with pressure rods. The handles can be rotated with two hands at the same time, and forming is finished after one-time operation. The symmetric form of a dental arch wire can be guaranteed, and the forming steps are simplified. The operation time of a doctor is saved, and the requirements of operation skills of a doctor are reduced. Injuries of fingers of a doctor are avoided and labour and time are saved.

Description

The arch wire former of depression bar is established at two ends
Technical field
The present invention relates to a kind of type medical instrument for dental use, be specifically related to the arch wire former that depression bar is established at a kind of two ends.
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, before rectification, first need arch wire to carry out the bending forming of definite shape, and bend while being shaped, just must use special-purpose arch wire former.At present, the arch wire former structure of using is clinically: integral body is dumbbell shaped, cylindric moulding middle handle that connects two ends by axle, only on a handle, establish depression bar, clinician is placed on size with it by arch wire and matches in the groove of moulding, then with left hand thumb, push down arch wire one end, by turning handle, drive depression bar moulding surface rotation, arch wire is bent right and left and be shaped to be applicable to dental arch shape.
But there is following drawback in this arch former:
1, need molding at twice, in this process, arch wire easily departs from groove generation 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 improving 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 to overcome deficiency of the prior art, the arch wire former that provides a kind of two ends to establish depression bar.
In order to solve the problems of the technologies described above, the present invention adopts following solution:
The arch wire former that provides a kind of two ends to establish depression bar, comprises and is positioned at columned moulding of axle middle part, the circumferencial direction at moulding outer surface along its cross section is provided with for placing the groove of arch wire; Handle is established respectively at axle two ends, and wherein depression bar is established in one handle inner side; Two handles are all sheathed on axle and can and pivot along axial displacement; Another handle inner side is also provided with depression bar; Two depression bars are all parallel with axle, and its lower surface is cambered surface, and tangent with moulding outer surface circumference.
In the present invention, described depression bar is cylindric, and this depression bar cylindrical surface and moulding outer surface circumference are tangent, and during turning handle, cylindrical depression bar can paste moulding surface rotation.
In the present invention, described moulding nested and be fixed on axle, between moulding and axle, be interference fit.
In the present invention, through hole established by described handle and counterbore is established in outer end, and axle passes handle through hole and is connected with the steady pin in being located at counterbore.
In the present invention, described axle is embedded in steady pin and both are interference fit.
Compared with prior art, the invention has the beneficial effects as follows:
1, compare with existing arch wire former, the handle at this product two ends, all with depression bar, can rotate by two handss simultaneously, and once-through operation can be shaped; Not only guaranteed that dental arch filament form is symmetrical, and simplified forming step.
2, save doctor's operating time, doctor's operation skill is required to reduce; Avoid doctor's finger injuries, time saving and energy saving.

Fig. 1 is the front view of product closure state of the present invention;
Fig. 2 is the left view of product closure state of the present invention;
Fig. 3 is the top view of product closure state of the present invention;
Fig. 4 is the schematic diagram of product open mode of the present invention;
Reference numeral: axle 1, moulding 2, groove 3, handle 4, handle 5, depression bar 6 and depression bar 7.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate content of the present invention, but should not be construed as the present invention, want protection domain to only limit to this.
As shown in Figure 1, the arch wire former that depression bar is established at two ends comprises and is positioned at columned moulding 2 of axle 1 middle part, at moulding 2 outer surfaces, along the circumferencial direction in its cross section, is provided with several for placing the groove 3 of arch wire.The width of groove 3 be 0.016 ", 0.017 ", 0.018 ", 0.019 ", 0.022 " equidimension (English unit), the degree of depth is 0.025 " (English unit), mate with the size of square arch wire by this size.
The two ends of axle 1 are established respectively 4,5, two handles of handle and are all sheathed on axle 1 and can rotate along axle 1 displacement with around axle 1.Wherein depression bar 7 is established in the inner side of handle 4, and it is all parallel with the direction of axle 1 that the inner side of handle 5 is provided with 6, two depression bars of depression bar 6,7.
Depression bar 6,7 in the present embodiment is cylindric, and tangent with moulding 2 outer surface circumference, and during turning handle, cylindrical depression bar can paste the surface rotation of moulding 2.
Moulding 2 nested and be fixed on axle 1, and both are interference fit.Through hole established by handle 4,5 and counterbore is established in outer end, and axle 1 passes through hole and is connected with the steady pin interference fit that is arranged in counterbore.Therefore handle 4,5 can, along axle 1 displacement, be realized depression bar 6,7 displacements to push down dental arch filament; Handle 4,5 also can be realized depression bar 6,7 rotations at moulding 2 outer surfaces around axle 1 rotation, reaches the effect of shaping dental arch filament.
The using method of this product:
Get the square arch wire of certain length, to two ends pulling handle 4,5, the stage casing of square arch wire is embedded in corresponding size groove 3, the handle 4,5 that draws two ends in makes depression bar 6,7 be positioned at the surface of moulding 2 and push down arch wire.Then by rotating two ends handle 4,5, drive depression bar 6,7 to rotate towards rightabout, thereby the side's of making arch wire completes plastotype, obtain needed dental arch filament.
