Description

Mouth cavity orthodontic multipurpose pincers

Affiliated technical field

This utility model relates to the just abnormal multipurpose pincers of a kind of human oral cavity, belongs to the special-purpose medical apparatus and instruments of mouth cavity orthodontic.

Background technology

When using fixed appliance and rescuing wrong  deformity, the doctor need with bracket with rescue arch wire and couple together to reach the orthodontic treatment purpose.Present common connected mode is will rescue the arch wire ligation on the holder that cements in tooth lip side is poor with metal ligation silk, its process is: earlier the rustless steel ligation silk of diameter 0.2mm or 0.25mm is cut into the long short ligation silk of 50.0mm, be converted into " U " type, reuse ligature forceps (needle holder that is used for performing the operation replacement) clamping two ends more, the top is enclosed within on the bracket, the ligature forceps that turns clockwise make the ligation silk in the shape of a spiral shape tighten, cut with the skilled worker apart from its root 2.0mm place then or excising forceps hinge disconnected, remove the trip end, with the terminal propeller of ligation silk the remaining end of ligation silk is pushed the wedge-like gap location of adjacency between arch wire tongue palate side or tooth at last, to avoid the lesion ports transmucosal.This process doctor need be used alternatingly ligature forceps, the skilled worker cuts (or excising forceps) and three kinds of instruments of the terminal propeller of ligation silk, palikinesia is many, inefficiency, labor intensity is big, the other operating time of chair is long, and the ligation silk free-end of cut-out is wayward, often falls into patient's mouth and causes unnecessary injury.

Summary of the invention

Just need three replacing instruments can finish bracket and this lengthy and tedious program of arch wire ligation on every tooth in order to overcome doctor in above-mentioned original ligation technology, this utility model provides a kind of mouth cavity orthodontic multipurpose pincers, these pincers not only integrate the multiple function of the terminal propeller of ligature forceps, excising forceps and ligation, and have ligation silk free-end clamping action, when cutting off the ligation silk, clamp free-end and make it avoid falling into patient's mouth.These pincers also can be used for twining long ligation silk making short ligation silk and to bend steel wire in addition, one-object-many-purposes, easy to use fast.Reduce palikinesia, alleviated doctor's labor intensity, improved the worker and used efficient, shortened the other operating time of chair, reduced the instrument number of times that stretches in the oral cavity.

The technical scheme that its technical problem that solves this utility model adopts is: respectively to same direction projection, is Baltimore groove at two head ends of pincers beak during the occluding forceps beak herein; Be provided with the semilune chase below in tooth socket bed, straight sides is an excising forceps, is positioned at above-mentioned pincers beak head end protrusion direction rightabout, and curvilinear sides is a little less than the tooth socket bed of pincers cutting edge of a knife or a sword height, is used for clamping ligation silk free-end; Two beak tail ends of nearly joint, a side is the smooth forceps bed that is provided with chase, opposite side is the semicylinder shape, is used to bend steel wire; The engaging tooth place of pincers handle is provided with circular opening, is used to make short ligation silk.Two pincers beaks and two pincers handles need be used and can produce the above-mentioned functions effect.

The beneficial effects of the utility model are: this utility model mouth cavity orthodontic multipurpose pincers have been compared following beneficial effect with the required multiple instrument of traditional mouth cavity orthodontic technology.1. collect ligature forceps, excising forceps, the multiple function of the terminal propeller of ligation silk all over the body in these multipurpose pincers; 2. the free-end clamping can be clamped free-end in excising forceps ligation silk, avoid falling into patient's mouth; 3. these multipurpose pincers can be used to twine long ligation silk in order to make short ligation silk and to bend steel wire; 4. reduce palikinesia and labor intensity, improved work efficiency, shortened the other operating time of chair; 5. reduced and stretched into the oral cavity number of times, alleviated the patient suffering.
