Background technology
The clinical oral inspection often need be measured the size of mouth opening and gone up the degree that mandibular teeth covers; Whether diagnosis on this basis suffers from the disease that influences the size of dehiscing; Like temporomandibular joint disease, jaw facial deformity etc., for the classification and the treatment of disease provides data.
At present, the length measuring instrument that uses clinically at Oral and Maxillofacial Surgery, Prosthodontics, Orthodontics etc. is common straight lattice chi.Though easy and general, but still there are a lot of drawbacks with straight lattice chi measurement.For example: manual measurement is unstable; The naked eyes error in reading is big; Manipulation accuracy is not high; Repeated measurement is prone to cause patient's overlong time of dehiscing, and muscle produces tired and influences the accuracy of measurement data.Domestic, Zhang Xiaoge, Zhao Zhihe etc. once applied in 2009 07 month " oral cavity measuring device " patent (application number/patent No.: 200920082493), it be a kind of be the main arc gauge that the oral cavity is measured with the manual measurement.But manual measurement is inconvenient, and the problem that the naked eyes error in reading is bigger still exists.Simultaneously, in order to adapt to the different measuring environment and to require also the needs knockout screw to change difform flexible handle head and main handle head, and need the multiple part of outfit, complex operation.
So far, the oral cavity special measurement chi that does not also have ability direct electron demonstration numerical value when measuring both at home and abroad.
The utility model content
The purpose of this utility model provides a kind of oral cavity and uses the digital display dip stick, and is easy to operate, portable, and function is many, and degree of accuracy is high, and the strength of materials is high, and is nontoxic, is prone to production and processing, and cost is low.
In order to achieve the above object, this utility model adopts following technical scheme:
The digital display dip stick is used in a kind of oral cavity of this utility model; The acrylic dianegative, magneto-optic grid device for digit-displaying, the compound magnetic sheet of carbon fiber that comprise trapezoidal shape; The last base of the acrylic dianegative of said trapezoidal shape and the angle of hypotenuse are 60 degree; Said magneto-optic grid device for digit-displaying is fixed on last base one end of the acrylic dianegative of trapezoidal shape; The compound magnetic sheet of carbon fiber passes magneto-optic grid device for digit-displaying, and is positioned at the chute at place, last base of the acrylic dianegative of trapezoidal shape, and the compound magnetic sheet of carbon fiber can slide on chute.
Wherein, the compound magnetic sheet of said carbon fiber is made up of carbon fiber slip chi and magneto-optic screen, and wherein, the magneto-optic screen sticks on the one side of carbon fiber slip chi.
Wherein, said magneto-optic grid device for digit-displaying is by light-emitting diode display, magnetic head, and displacement transducer is formed.
Owing to taked above technical scheme, the advantage of this utility model is:
(1) easy to operate, portable;
(2) function is many, can be used for conventional examination of mouth, and the measurement of temporomandibular joint disease, the isochronous opening degree of wrong jaw abnormality, tooth level of coverage etc.;
(3) degree of accuracy is high, and liquid crystal display numerical value reads conveniently.Shortcomings such as common lattice chi manual measurement is unstable, the naked eyes error in reading is big have been avoided;
(4) strength of materials high, resistance to wear, nontoxic, environmental protection, but use repeatedly after the alcohol wipe sterilization;
(5) be prone to production and processing, cost is low, and is cheap.

The specific embodiment
Following examples are used to explain this utility model, but are not used for limiting the scope of this utility model.
Referring to Fig. 1～Fig. 3; This utility model is that the digital display dip stick is used in a kind of oral cavity; Acrylic dianegative 1, magneto-optic grid device for digit-displaying 4, the compound magnetic sheet of carbon fiber by trapezoidal shape are formed; The last base 6 of the acrylic dianegative 1 of said trapezoidal shape is 60 degree with the angle of hypotenuse 7, and said magneto-optic grid device for digit-displaying 4 is fixed on last base 6 one ends of the acrylic dianegative 1 of trapezoidal shape, and the compound magnetic sheet of carbon fiber passes magneto-optic grid device for digit-displaying 4; And being positioned at the chute 3 at 6 places, last base of the acrylic dianegative 1 of trapezoidal shape, the compound magnetic sheet of carbon fiber can slide on chute 3.The last base 6 of the acrylic dianegative 1 of trapezoidal shape, bottom 8 length are respectively 130mm, 110mm, and height is 50mm, and thick is 12mm, and last base 6 is 60 degree with the angle of hypotenuse 7, is the function angle of this utility model.Carbon fiber slip chi 2 is about 130mm, and wide 15mm adopts the equilateral triangle principle to realize measuring indirectly, slip directly on light-emitting diode display 5, show numerical value apart from size, measuring range 0～60mm, degree of accuracy reaches 0.1mm.This dip stick has been used magneto-optic grid digital display technology, and this techniques make use Morie fringe principle is represented the high accuracy displacement sensor of linear displacement amount through the digital form of magnetic head and digital display meter, and measuring accuracy can reach 0.1mm.Magneto-optic grid measuring method is measured association, National Quality & Technology Inspection Bureau's approval by the world.
The method for using of this utility model: when measuring the mouth opening size; The last base 6 of the acrylic dianegative 1 of the trapezoidal shape of this utility model is arrived to upper and lower jaw central incisor incisxal edge respectively with hypotenuse 7 (goes up base 6 and arrives to upper tooth and upper lip; Hypotenuse 7 arrives to lower tooth and lower lip); And along with mouth opening increases, the function angle of dip stick (promptly going up angle 60 degree of base and hypotenuse) further stretched in the oral cavity, and upper and lower jaw central incisor incisxal edge slides along last base 6 and hypotenuse 7.Simultaneously, the lip side of maxillary central incisors promotes compound magnetic sheet one end of carbon fiber and slides to tailing edge chute 3, on light-emitting diode display 5, directly shows the distance that the compound magnetic sheet of carbon fiber slides, and is the measured value of mouth opening size.In measuring process, through keeping dip stick not take place to have a down dip with reference to the vertical graduation mark on the compound magnetic sheet of carbon fiber.The mouth opening of edentulous jaw is measured then and is measured along horizontal plane and inclined-plane slip through upper and lower alveolar ridge crest.In like manner, can measure the interdental overburden depth of lower jaw.Because the last base 6 of the acrylic dianegative 1 of trapezoidal shape is identical with the distance that hypotenuse 7 enters the mouth; And the angle of the last base 6 of the acrylic dianegative 1 of trapezoidal shape and hypotenuse 7 is 60 degree; So; Last base 6, hypotenuse 7 and to go up the triangle that base 6 and another fillet of hypotenuse 7 form be equilateral triangle, another fillet of last base 6 and hypotenuse 7 is mouth opening just.The distance that base 6 enters the mouth in the measurement in fact just records the size of mouth opening.
Obviously, the foregoing description of this utility model only be for explain clearly that this utility model does for example, and be not to be qualification to the embodiment of this utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to this utility model is extended out or change still are in the row of the protection domain of this utility model.
