Technical Field

The invention relates to the technical field of bracket dismantling, in particular to a digital display type bracket dismantling instrument.

Background

With the pursuit of beauty, more and more people wear brackets for orthodontics of teeth, so that the inclined teeth become more orderly. The support groove is an important part of the fixed correction technology, the bonding agent is directly bonded on the surface of the dental crown, the arch wire applies various types of correction force to the tooth through the support groove, the common support groove is mainly made of stainless steel and biological ceramic, and the main effect of the support groove is that the arch wire is fixed, so that the arch wire can better exert the function, the force is corrected through transmission, the three-dimensional movement of the tooth is controlled, and the purpose of orthodontic correction is achieved. After the teeth are corrected, the bracket fixed to the teeth needs to be removed, and usually, a doctor will remove the bracket by using a clamp.

The prior Chinese patent with publication number CN105455908A discloses a bracket removing pliers, which comprises pliers handles hinged together, wherein the front end of the pliers handle is extended to form a clamping arm, the upper surface of the clamping arm is a declination inclined plane, the lower surface of the clamping arm is an upwards inclined plane, the front end of the clamping arm is provided with a pliers beak, the pliers beak and the clamping arm form a V-shaped connecting structure, the projection of the appearance outline of the pliers beak on a vertical plane is built in the appearance outline of the pliers handle, the pliers beak is of an equal-section wedge-shaped structure with an arc-shaped cutting edge, the arc-shaped cutting edge of the pliers beak is arranged towards the inner side and protrudes out of the inner side of the clamping arm, and when the pliers handles are completely closed, a preset gap distance is kept between the arc-. When the bracket is used, the forceps beaks are mutually occluded on two sides of the bracket, so that the bracket can be detached.

However, the bracket removing forceps have the following disadvantages: because it is not provided with pressure measurement on it, when the pincers handle was operating, medical personnel only can rely on the experience of oneself to control the dynamics, and unable accurate control, if the clamping-force is too big, when demolising, not only can cause great misery to patient, but also can cause the damage to the tooth surface, if the clamping-force undersize, the phenomenon that can't pull down in the support groove can appear.
