Abstract

The invention discloses open-type NiTi tension springs, it is formed by single line material bending, several section spiral lines, several sections of bending lines and the tail wire positioned at both ends are formed after bending, the helix and the bending line, which mutually alternate to be formed, has formed the elastic part that elastic force acts on, all helixes are located at then, bending line or so is distributed, and the tail wire is located at both ends；The outermost end endpoint of all bending lines positioned at left side and the spacing between the outermost end endpoint of the corresponding bending line on right side are equal, and a breach that can be used for being included in middleware is formed positioned at the bending line in left side and between the bending line on right side；It the advantage is that：Single-open spring has clamping opening, alignment sleeve that can directly be pressed into, and suitable length is replaced again after can also being taken out according to the feeling of patient；Later stage can also be replaced as needed, and to maintain suitable elastic force, operation is fairly simple, is easy left-hand seat, convenient disassembly.

Description

Open-type NiTi tension spring

Technical field

The present invention relates to the auxiliary tools used in a kind of operation on oral cavity；Specifically open-type NiTi tension spring.

Background technology

The basic principle of oral cavity corrective procedure is exactly that a tooth position is adjusted out between two teeth, then needing righting Tooth move on in normal alignment and righting, common practice are exactly that bracket or set casting crown are glued on needing mobile tooth, Then it is moved using the elastic force of spring.

When first installation, needs to carry out glue gluing to spring, confine its elastic force, it in this way could be in the case that inelastic Installation is completed, then, needs medication washing to remove the glue on spring, spring is made to restore elastic force；Operating time and material cost are higher, The opening time of patient is also longer.

Spring is sleeved on casing or arch wire, can not be taken out or be replaced halfway；In the later stage, then need by constantly increasing The mode of shimming, or change screw pitch or the number of turns, the elastic force that the tooth that need to be moved could be given lasting with pliers；If replacing bullet Spring is to adjust elastic force, it is necessary to dismount package unit.

Invention content

The present invention a kind of can not dismantle in view of the shortcomings of the prior art, providing according to the feeling and later stage needs of patient Under the premise of casting crown, the replaceable open-type NiTi tension spring in midway.

In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：Open-type NiTi pulling force bullet Spring is formed by single line material bending, and several section spiral lines, several sections of bending lines and the tail wire positioned at both ends are formed after bending, The helix and the bending line, which mutually alternate to be formed, has formed the elastic part that elastic force acts on, and all helixes are located at together then, Bending line or so is distributed, and the tail wire is located at both ends；The outermost end endpoint of all bending lines positioned at left side and it is located at Spacing between the outermost end endpoint of the corresponding bending line on right side is equal, positioned at left side the bending line and be located at A breach that can be used for being included in middleware is formed between the bending line on right side.

As an optimization, the line of the outermost end endpoint of all bending lines positioned at left side is parallel with axis, owns Line positioned at the outermost end endpoint of the bending line on right side is parallel with axis, and the breach is parallel with axis.

Alternatively, the line of the outermost end endpoint of all bending lines positioned at left side is using axis as center line helically line The line of shape, the outermost end endpoint of all bending lines positioned at right side is helically linear by center line of axis, the breach It is helically linear.

The bending line is V-shaped, U-shaped or front end are linearly.

The tail wire is concordant；End block is installed on the tail wire；Jagged, the notch and institute is arranged in the end block It is consistent to state breach direction.

Compared with prior art, the present invention having the advantages that：Single-open spring has clamping opening, alignment sleeve or bow Silk can be directly pressed into, and suitable length is replaced again after can also being taken out according to the feeling of patient；Later stage can also be according to need It is replaced, to maintain suitable elastic force, operation is fairly simple, is easy left-hand seat, convenient disassembly.

Specific implementation mode

Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：As shown in figures 1 to 6, it marks such as Under：Helix 1, bending line 2, tail wire 3, breach 4, end block 5, notch 6, middleware 7.

Open-type NiTi tension spring is formed by single line material bending, forms several section spiral lines 1, Ruo Ganduan after bending Bending line 2 and tail wire 3 positioned at both ends, helix and bending line, which mutually alternate to be formed, form the elastic part that elastic force acts on, All helixes are located at then, and bending line or so distribution, tail wire is located at both ends；The outermost end of all bending lines positioned at left side Endpoint and spacing between the outermost end endpoint of the corresponding bending line on right side are equal, are located at the bending line in left side And a breach 4 that can be used for being included in middleware 7 is formed between the bending line on right side, this middleware can be casing Or arch wire, that is to say, that the device having been fixed on tooth can not removed, be mounted directly, remove or replace the application The spring of structure, this is that corrective procedure brings great convenience.

The line of the outermost end endpoint of all bending lines positioned at left side is parallel with axis, all bendings positioned at right side The line of the outermost end endpoint of line is parallel with axis, and breach is parallel with axis, that is to say, that breach is parallel, installation side Just.

As variation, the line of the outermost end endpoint of all bending lines positioned at left side is using axis as center line helically line The line of shape, the outermost end endpoint of all bending lines positioned at right side is helically linear by center line of axis, breach helically line Shape, after installation, no matter in what angle, middleware can all hang several bending lines, it is not easy to runaway, as shown in Figure 6.

As deformation, bending line is V-shaped, U-shaped or front end are linearly, it is possibility to have other shapes.

Tail wire is concordant, it is not easy to hurt muscle or skin in oral cavity；It is also equipped with end block 5 on tail wire, can rise To better protective action；End block is also provided with notch 6, and notch is consistent with breach direction, to install.

The application, which is not only appropriate in dental operation, to be used, and can also be used in other industrial products.
