Description

Tooth opener

Technical field

This utility model relates to the utensil of medical mouth open, specifically is a kind of Tooth opener.

Background technology

When the treatment patient needs mouth open, there are a lot of method and apparatus to open patient's mouth greatly, or keep the open configuration of needs.But, when treatment target refusal is dehisced, or can't opening the time, but make troubles to the medical worker, so that can't treat, or affect treatment adversely.

Chinese patent 2233722 discloses a kind of " novel operation on oral cavity gag ", be on the basis of former Vickers gag, with the arch form supporting frame upper free-end, prolong its arc form long axis and open the tooth hook groove rail of 4-6cm, make between tooth hook displacement field and enlarge, adorn the illumination support arm of lifting thereupon at elevating lever outside of belly spiral shell, and in catheter hub plug-in mounting fibre light guide beam guide tube, for the wild illumination of art.

Chinese patent 2291891 disclosed " frame-type gag " then is connected into quadra and a spiral handle by diaxon by three metallic plates to be formed.During use gag tongue arm is put into the oral cavity, tooth is entered in the groove, the rotating screw handle retracts the oral cavity.

Domestic various gags are to use under the prerequisite that patient can cooperate with on one's own initiative at present, or the oral cavity is opened greatly inadequately after dehiscing, and maybe can not continue to keep ideal open configuration.Open one's mouth and opening and can not carry out to the patient that gnathospasma or refusal are dehisced.

Summary of the invention

This utility model is to dehisce in order to solve refusal, or can't opening the time, make the oral cavity, particularly go up a kind of Tooth opener of lower teeth unlatching.

This utility model designs according to following technical scheme.

A kind of Tooth opener, its two jaw tong handle one ends arranged side by side that can be the folding of " V " font are coupling by the folding axle center, the other end is affixed left and right flexible jaw clip respectively, the left and right flexible jaw clip far-end outside sets firmly location Xiao Ding for the left and right sides chin rest of pegging graft respectively, near-end is respectively the corresponding fork of joining of pegging graft, run through being provided with and the wide adjusting spiral shell of the vertical cheek of its major axis pivot on two jaw tong handles, the curved jaw pads of arc such as the curved inboard spiral-lock of the arc of left and right flexible jaw clip joint portion.

During use, estimated lower jaw length, the jaw pad is stuck under the lip, is impetus with the chin, makes two angle of mandibles slip into the left and right sides chin rest, makes two angle of mandibles of chin rest support, and as fulcrum, jaw tong handle is pressed down, and mandibular bone moves downward, the breakdown tooth.Mandibular bone can the outside mobile chin rest than long time; According to the wide scalable spiral shell of jaw pivot, drive big jaw folder, about corresponding outer the moving of the fork of joining of pegging graft, avoid firmly after strain of jaw folder.

She Ji this utility model is reasonable in design like this, and is novel, and solve some people refusal and dehisce, or a difficult problem that can't opening, satisfied as long as going up lower tooth opens＞5mm, can satisfy the requirement of using various gags, for medical mouth gag provides new utensil.
