The oral cavity measuring device

Technical field

This utility model relates to a kind of dental instrument, relates in particular to a kind of oral cavity measuring device.

Background technology

Along with the popularizing of the raising of The development in society and economy, level of science and culture, medical skill, lifting that people required quality of life, and oral cavity basic research and clinical technology deepen continuously and perfect, the patient who carries out treatments such as mouth cavity orthodontic and reparation increases day by day.

Model analysis is the mouth cavity orthodontic clinical diagnosis, works out an important step in the treatment plan, and comprise and observe dental arch shape, gap distribution position, and model measurement.Measure content model measurement comprises arch width measurement, arch length measurement, the SpeeShi curve distance is measured and crowding analysis etc.The Measurement and analysis of model has considerable effect in the mouth cavity orthodontic diagnostic system.

Proximal surface goes glaze as one of non-exodontia orthodontic therapy method, and is comparatively commonly used clinically, especially rescues in the technology being widely used in no bracket stealth.The amount that proximal surface goes the amount of glaze promptly to obtain additional clearance also needs accurately to measure.In oral repairing clinic work, also often need carry out the measurement of distance and thickness in addition.

Widely used clinically at present is to measure with slide gauge or divider etc.But because clinical oral working particularity, often need in patient's mouth, directly carry out range measurement, there is the inconvenience part in traditional survey tool, in mouth, directly measure comparatively difficulty more greatly as volume, can not take measurement of an angle, measurement data is directly read in inconvenience and measure shortcomings such as efficient is low.

The utility model content

The purpose of this utility model just is to provide a kind of oral cavity measuring device that addresses the above problem.

To achieve these goals, the technical solution adopted in the utility model is such: isometric main handle and flexible handle are divided into the long section of main handle respectively in the place of their equal lengths, the main handle head, flexible handle and flexible handle head, above-mentioned four part intersections connect with torsionspring and are movable fixing with screw, at the terminal curved scale chi that an expression length is arranged of the long section of main handle, curved scale chi one end links to each other with the long section of main handle, the other end is a catch, the end of the long section of flexible handle be one with the prong of curved scale chi coupling, the long section of flexible handle terminal can be by pulling flexible handle because the effect of torsionspring and between long section end of the main handle on the curved scale chi and catch, sliding; Main handle head straight-bar or " L " shape for from the intersection to the end, diminishing gradually, the flexible handle head end is straight-bar or " L " shape for diminishing gradually also, and intersect with the end of main handle head, make main handle head and flexible handle head intersect " V " shape or " U " shape;

As preferably, the zero graduation of described curved scale chi is positioned at the catch place;

As preferably, the side of described flexible handle is provided with burr;

As preferably, the tow sides of described main handle are provided with the length scale;

As preferably, the curved scale chi all has scale at tow sides, and is provided with angle index on the tow sides of curved scale chi;

As preferably, all parts adopt medical stainless steels.

Compared with prior art, advantage of the present utility model is: simple and practical, and efficient height, safety and sanitation. owing to adopt medical stainless steel, can sterilize repeatedly; Because flexible handle is provided with burr, can be anti-skidding, reduce maloperation; Because the intersection adopts screw to connect, structure is flexible, change difform flexible handle head and main handle head after the removable fasteners,, adapting to different measurement environment and requirement, and two-sided angle and the distance scale of all being provided with of curved scale chi, conveniently reading. measuring range comprises distance, thickness, angles etc. have wide range of applications, but fields such as extensive use mouth cavity orthodontic and reparation.

The utility model is described in further detail below in conjunction with accompanying drawing.
