Abstract

The utility model relates to a rescue ware technical field, and disclose a push away spring and rectify ware, need not change and push away the spring, only need the dismouting change the adjusting block of different thickness, make the distance between two adjusting blocks diminish can. When the arch wire is replaced, the opening of the U-shaped groove is inward, so that the position of the arch wire is not influenced. Set up like this, need not tailor again and push away the spring to and take off whole arch wire and just can change and push away the spring, and it is more convenient to change, improves work efficiency.

Description

Push spring corrector

Technical Field

The utility model relates to a rescue ware technical field specifically is a push spring ware of rectifying.

Background

The malocclusion is treated by orthodontics or surgical operations and the like, and refers to deformity of teeth, jaw bones and craniofacial surfaces caused by congenital factors or acquired factors in the growth and development process of children, and is classified as three common diseases of oral cavities together with decayed teeth and periodontal diseases. Among orthodontic techniques, the push spring orthosis technique is a technique for pushing two teeth apart. When the push spring corrector is used for treatment, due to the change of correction effect, the push spring needs to be replaced at any time, but the push spring of the existing push spring corrector is difficult to replace, and the existing push spring corrector can be replaced only by cutting the arch wire for many times and completely taking down the arch wire.

SUMMERY OF THE UTILITY MODEL

The utility model mainly provides a push spring corrector, which solves the problems that the push spring of the existing push spring corrector is difficult to replace and the arch wire needs to be cut out for many times and taken down completely to replace.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the push spring corrector comprises a plurality of support grooves bonded on the surface of a dental crown, an arch wire penetrating through the support groove and a push spring, wherein an adjusting block used for adjusting the compression length of the push spring is detachably connected to the support grooves, and U-shaped grooves matched with the arch wire are arranged on the adjusting block corresponding to the grooves of the support grooves. When the push spring is used, the push spring does not need to be replaced, and only the adjusting blocks with different thicknesses need to be disassembled and replaced, so that the distance between the two adjusting blocks is reduced. When the arch wire is replaced, the opening of the U-shaped groove is inward, so that the position of the arch wire is not influenced. Set up like this, need not tailor again and push away the spring to and take off whole arch wire and just can change and push away the spring, and it is more convenient to change, improves work efficiency.

Furthermore, a first socket is arranged on the bracket, and a pin matched with the first socket is arranged on the adjusting block. Through setting up first socket and participating in the complex connected mode, the structure is simpler, and it is more convenient to change.

Further, the adjusting device also comprises a base support, wherein a second socket matched with the adjusting block is arranged on the base support. By the arrangement, the push spring on the base can be quickly replaced.

Furthermore, a limiting needle is arranged on the base support, and a needle hole matched with the limiting needle is formed in the adjusting block. By the arrangement, the limitation of the adjusting block at the base can be more stable.

Furthermore, an end groove matched with the push spring is arranged on the outer side surface of the adjusting block. Set up like this, push away the both ends of spring and can pass through the compression process back card that resets again and go into the end inslot, let and push away the spring and do not rock, and let the adjusting block at both ends block the back and more be difficult to deviate from.

Has the advantages that: when the push spring is used, the push spring does not need to be replaced, and only the adjusting blocks with different thicknesses need to be disassembled and replaced, so that the distance between the two adjusting blocks is reduced. When the arch wire is replaced, the opening of the U-shaped groove is inward, so that the position of the arch wire is not influenced. Set up like this, need not tailor again and push away the spring to and take off whole arch wire and just can change and push away the spring, and it is more convenient to change, improves work efficiency.

FIG. 2 is a schematic side view of the base of the present embodiment;

fig. 3 is a front view of the adjusting block of the present embodiment.

Reference numerals: the bracket comprises a bracket 1, an arch wire 2, a push spring 3, an adjusting block 4, a U-shaped groove 5, a pin 6, a base 7, a limit pin 8 and an end groove 9.

Detailed Description

The technical solution of the spring-pushing corrector according to the present invention will be further described in detail with reference to the following embodiments.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, 2 and 3, the push spring 3 appliance of the present embodiment includes a plurality of brackets 1 adhered to the surface of the dental crown, an archwire 2 passing through the grooves of the brackets 1, and a push spring 3, wherein an adjusting block 4 for adjusting the length of the push spring 3 in compression is detachably connected to the bracket 1, and a U-shaped groove 5 matched with the archwire 2 is provided in the adjusting block 4 corresponding to the groove of the bracket 1. The bracket 1 is provided with a first socket, and the adjusting block 4 is provided with a pin 6 matched with the first socket. The adjusting block is characterized by further comprising a base support 7, wherein a second socket matched with the adjusting block 4 is arranged on the base support 7. The base support 7 is provided with a limiting needle 8, and the adjusting block 4 is provided with a needle hole matched with the limiting needle 8. An end groove 9 matched with the push spring 3 is arranged on the outer side surface of the adjusting block 4. When the device is used, the push spring 3 does not need to be replaced, and only the adjusting blocks 4 with different thicknesses need to be disassembled and replaced, so that the distance between the two adjusting blocks 4 is reduced. When the arch wire is replaced, the opening of the U-shaped groove 5 is inward, and the position of the arch wire 2 cannot be influenced. Set up like this, need not tailor again and push away spring 3 to and take off whole arch wire 2 and just can change and push away spring 3, and it is more convenient to change, improves work efficiency.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
