Nickel-titanium wire heating, bending and shaping pliers

Abstract

The invention relates to pliers, in particular to nickel-titanium wire heating, bending and shaping pliers for heating and shaping a nickel-titanium wire for orthodontic treatment. The nickel-titaniumwire heating, bending and shaping pliers comprise two plier bodies and clamping ends, wherein the clamping ends are correspondingly arranged at the tops of the plier bodies; fixing seats are correspondingly arranged on the inner sides of the clamping ends; working blocks are correspondingly arranged at the working ends of the fixing seats; one end of each of two lead wires is connected with the corresponding fixing seat; the other end of each lead wire is connected with one corresponding plug; and the two plugs are connected with a power source. The nickel-titanium wire heating, bending and shaping pliers provided by the invention have the following advantages and effects: the nickel-titanium wire has the memory function and is easy to rebound after being bent at normal temperature, so that plier heads can be powered on, the nickel-titanium wire can be heated when the electric current passes through the nickel-titanium wire, the internal stress of an arch wire can be eliminated when the nickel-titanium wire is shaped, the nickel-titanium wire can be prevented from rebounding after being bent and shaped, and then nickel-titanium wires of different shapes can be manufactured according to different malpositioned teeth for orthodontic treatment.

Description

technical field [0001] The invention relates to a pair of pliers, in particular to a nickel-titanium wire heating and bending setting pliers for heating and setting the nickel-titanium wire used for orthodontics. Background technique [0002] Now the teeth are not very neat, and the teeth need to be corrected, but most of the materials for the correction of the teeth are steel wires or nickel-titanium wires, but the rigidity of the steel wires is large, which is not conducive to the correction of the teeth. The shape of nickel-titanium wires The fixation is single, and the teeth in special parts cannot be over-corrected, so the current trend is to use nickel-titanium wire to bend and re-correct the teeth, but because the nickel-titanium wire has a super-elastic memory function, it can be bent in a specific part The shape is very difficult. When it is folded into a good shape and fixed on the teeth, the temperature of the nickel-titanium wire will increase due to the temperat...

[0002] Now the teeth are not very neat, and the teeth need to be corrected, but most of the materials for the correction of the teeth are steel wires or nickel-titanium wires, but the rigidity of the steel wires is large, which is not conducive to the correction of the teeth. The shape of nickel-titanium wires The fixation is single, and the teeth in special parts cannot be over-corrected, so the current trend is to use nickel-titanium wire to bend and re-correct the teeth, but because the nickel-titanium wire has a super-elastic memory function, it can be bent in a specific part The shape is very difficult. When it is folded into a good shape and fixed on the teeth, the nickel-titanium wire will return to its original shape due to the temperature of the oral cavity.
