Abstract

The utility model provides special purpose mouth orthodontic hinged wire scissors, which is formed by riveting two scissors each with a scissor mouth (1) and a scissor handle (3), one half of scissor adopts a straight and flat scissor mouth (1), another scissor mouth (1) is equipped with grooves (C). The grooves (C) are semi-round shape, which is arranged within 15 mm from the tip of the scissor mouth (1), the groove (C) at the highest top end of the scissor mouth (1) is 0.6 to 0.9 mm deep, and the other grooves (C) are 0.3 to 0.6 mm deep. The groove interval distance is 0.5 to 1.2 mm. The scissor mouth (1) with groove (C) can firmly nip the ligature wire, to effectively avoid the falling off of the ligature wire and the mouth bracket, to ensure the wire cutting quality during mouth orthodontic treatment, and to improve the efficiency.

Description

The special-purpose hinge silk of mouth cavity orthodontic is cut

Technical field

This utility model relates to oral cavity medical apparatus, is specifically related to the mouth cavity orthodontic tool scissors.

Background technology

Carry out in the clinical manipulation of mouth cavity orthodontic in hospital at present, after the arch wire ligation was fixing, the end that uses the Oral Repair crown scissors to make the ligation silk was handled more, when arch wire adjustment and replacing, cut off with the ligation silk that crown scissors will be fixed on the bracket wing in addition.Because two leaf shears cutting edges of crown scissors are straight, when shears ligation silk was terminal, usually slippage was difficult for cutting off, and because of the slippage of shears cutting edge produces the moment resilience force, bracket is come off from facing sometimes, influences the orthodontic treatment effect, the extended treatment time.

Summary of the invention

The purpose of this utility model just provides the tool scissors that a kind of novel mouth cavity orthodontic is used, and makes unlikely landing when shearing the ligation silk, avoids coming off because of the bracket that the cutting edge slippage causes, and guarantees the just abnormal yarn quality of cutting, and shortens treatment time.

Task of the present utility model is finished like this: design and produce the special-purpose hinge silk of a kind of mouth cavity orthodontic and cut, form with the two leaf shears riveteds of cutting handle by having clip, wherein the clip of a leaf shears is straight sword, and the clip of another leaf shears has groove.Clip groove semicircular in shape is opened in the most advanced and sophisticated 15mm scope of clip.Groove is a plurality of, and a gash depth most advanced at clip is 0.6～0.9mm, and remaining gash depth is 0.3～0.6mm, and separation is 0.5～1.2mm.Two leaf shears to cut a shape different, the cutting being long ellipticity of a side shears leaf of clip two with grooves, clip is the cutting being ellipticity of a side shears leaf of straight sword.Owing to have groove on the clip of a leaf shears, can vise the ligation silk securely, be convenient to shear.

On probation through trial-production, prove that this utility model can tighten the ligation silk easily cut off that the landing of ligation silk and oral cavity bracket came off when the clip groove can prevent to shear effectively, improve the just abnormal yarn quality of cutting, shorten treatment time, guarantee the orthodontic treatment effect, reached predetermined purpose preferably.

Fig. 2 is an open state sketch map of the present utility model;

Fig. 3 is clip of the present utility model (a 1) position structural representation.

Among the figure, the 1-clip, the 2-rivet, 3-cuts handle, the C-groove.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.Adopt medical stainless steel to make two leaf shears, the clip 1 long 20mm of a leaf shears, the top has groove C, cuts to be oblong, the long 40mm of endoporus to 3; The clip 1 of another leaf shears is straight sword, long 20mm, and it is oval cutting 3, the long 30mm of endoporus.Two leaf shears overlap, and with rivet 2 movable riveted joints, two leaf shears can be around rivet 2 opened with certain angle.Groove C semicircular in shape on the clip 1, the dark 0.8mm of groove C at clip 1 most advanced place, the dark 0.5mm of remaining groove C, separation is 1mm.Tungsten carbide button's steel all on the clip 1 of both sides.When carrying out the mouth cavity orthodontic treatment, a side clip 1 that has groove C can make things convenient for, vise securely the ligation silk that will shear, and the straight sword of opposite side clip 1 can successfully be sheared the ligation silk, the unlikely slippage that comes off.This utility model can guarantee shearing quality effectively, satisfies the needs of mouth cavity orthodontic, increases work efficiency, and shortens the orthodontic treatment time, alleviates patient's misery.

Claims
