Domestic micro-orthodontic force measuring device is based on in-vitro measurements at present, and measures orthodontic force indirectly by means of survey tools such as slide calliper rule.Need reprint the tooth mould, cost is than higher; By vernier caliper measurement, precision is not high, and error ratio is bigger; Need before measuring in addition with other arch wire and bracket colligation to the tooth mould, complicated operation, and also measurement is not to be same target.There is introduction that strain gauge is integrated in the sensitive bracket abroad, obtain orthodontic force by measuring stress, also just being used for external tooth mould measures, and can only measure a tooth mould at every turn, this kind method need be carried out date processing by computer, with stress transmission is corresponding power value, measures complexity, and just not being preferably, abnormal teacher grasps.
Summary of the invention
The invention provides and a kind ofly can realize conveniently that multiple tooth orthodontic force measures simultaneously, and the orthodontics orthodontic force measuring device based on force transducer that can in the oral cavity, directly measure.
The present invention adopts following technical scheme:
A kind of orthodontics orthodontic force measuring device based on force transducer, comprise fixed mount and measure main element, on fixed mount, be connected with arc frame, be provided with the governor motion that is used to adjust measurement main element present position at arc frame, described arc frame is connected with the measurement main element by described axial regulating mechanism, described measurement main element comprises that screw rod and elasticity firmly grasps pawl, firmly grasp in screw rod and elasticity and to be provided with adjustable pipe and force transducer between the pawl, one end of described adjustable pipe is connected with an end of screw rod, the other end of adjustable pipe is connected with an end of force transducer, the other end of force transducer and elasticity are firmly grasped ZHUANLIAN and are connect, and the other end of described screw rod is connected with governor motion.
Compared with prior art, the present invention has following advantage:
Utilize holddown groove in the arc frame can realize the angle quick adjustment of measuring device; Can realize the elastic of measuring device fast by adjusting nut; Can realize the attitude adjustment of checkout gear according to the attitude of tooth fast by adjustable pipe; Extract the plug pad out, (Fig. 1) the orthodontic force (see figure 6) that the arch wire distortion is produced passes to elasticity and firmly grasps pawl, and is delivered to force transducer, so just measure the size (reading from force transducer) of orthodontic force.The quantity of the checkout gear in the arc frame can be as required and rapid adjustment.Frock of the present invention dismounting, easy to assembly helps operations such as the sterilization of measuring device and maintenance.The measuring device of the present invention's design, structure is simple relatively, by means of force transducer, adjustable pipe and adjusting nut, can faster realize the measurement of orthodontic force in the oral cavity, delivery in the oral cavity, the process of turning over mould and cost have been saved, utilize this device to carry out the local device adjustment, can realize measuring simultaneously the orthodontic force that a plurality of teeth are subjected to according to the different attitudes of tooth.
