Abstract
The invention relates to an adjustable integrated type magnetic expansion appliance, which is an orthopedic device enabling upper jaw bones to open by pushing force generated by magnetic force repulsion. Two sections of structures which can be adjusted continuously are arranged inside the device, so that the expansion effect can reach a size of 9 mm. The device is provided with special resetting and tooth shape limiting structures, and the adjustability of the expansion action can be achieved through changing a pushing-out acting point and guaranteeing that no parts are installed additionally or replaced in the device.
Description
Technical field
The present invention relates to a kind of adjustable integral formula magnetic force and expand the bow orthotic device
Background technology
It is just abnormal clinical method commonly used that the method for employing Maxillary Expansion is rescued the patho-occlusions such as crowded dentition, intraversion, posterior cross bar, and expansion screw is at present the most frequently used expansion bow device, use for many years through clinical, its determined curative effect, but also exist initial force large but decay is fast, need frequent afterburning; Clinical manipulation is complicated, needs the patient to cooperate, and the child voluntarily reinforcing have risk; It is relatively poor to expand the bow effect stability, easily recurrence; The shortcoming such as not easy to clean.Other machinery expands the bow device and also has all deficiencies.Magnetic force is good because of the big or small measurability of its physical property and magnetic force; A kind of field force of hyperspace medium, and magnetic force substantially in time the decay, rescue insist on continuous; Good vector controlled is arranged; Can promote revascularization, improving the advantage such as osseous tissue microcirculation introduces in the just abnormal expansion bow, but magnetic force can along with magnet pitch from expansion, the strength sharply shortcoming such as minimizings and making is used limitedly, has the scholar to adopt to add the method for resin mat or place the mode such as magnetic piece between two magnetic piece and recover to rescue power and continue the expansion dental arch.But the operation of these methods is very complicated and be unfavorable for the maintenance of oral hygiene.It is a kind of orthotic device that the thrust of utilizing the magnetic homopolar-repulsion to produce expands jawbone that adjustable integral formula magnetic force expands the begg appliance device.It has good mechanical characteristic; Operate very convenient and do not need the patient afterburning voluntarily; The relatively constant stability that is conducive to expand bow of strength; Easy cleaning; Magnetic field can promote revascularization, improves the osseous tissue microcirculation, thereby accelerates the alveolar bone reconstruction.
Summary of the invention
The purpose of this invention is to provide a kind of easy to operately, mechanical characteristic is good, easy cleaning, and the adjustable integral formula magnetic force that is conducive to human body expands the begg appliance device.
Description of drawings
Fig. 1 is the structure chart of product of the present invention, 6. homopolarity is installed in opposite directions has up and down square box body that 7. top cover the seal neodymium iron boron magnetic body in 1., produce outward thrust, promote slide block 5., 3. slide block passes to push rod with power, 2. push rod step end promotes push pedal, and push pedal passes to the band that is fixed on the tooth with expansionary force, thereby realizes expanding bow.Or the plantation nail that push pedal promotes to be fixed on the upper jaw bone realizes expanding the bow purpose.After expanding for the first time the bow end, 4. the opposed release link in both sides is advanced to the centre, and push pedal end first limiting tooth A is held together to therebetween, the front end of push rod leans the profile of tooth angle, and the termination of push rod passes to push pedal with thrust, finishes and expands for the second time bow.And then release link advanced to the centre, and the second limiting tooth B is clamped, repeat for the second time process, finish whole expansion bow process, reach the purpose that expands bow.Product structure axonometric chart of the present invention is seen Fig. 6, expands for the first time to bend to begin to see Fig. 2, sees Fig. 3 in the expansion bow, expands for the second time to bend to finish and sees Fig. 4, and the expansion bow is finished and seen Fig. 5 for the third time, and spacing teeth groove is seen Fig. 7.Install each component diagram and see Fig. 8.
The specific embodiment
Adjustable integral formula magnetic force expands overall structure, push rod mode, profile of tooth position limiting structure, the reset mode of begg appliance device.
Claims (5)
1. one kind is expanded the begg appliance device, and its feature comprises that does not have a magnetic rectangular box, and there are two high magnetic flux magnets that peer is relative in rectangular box central authorities, and there is respectively the slide block with three push rods in the outside of magnet, and the left and right sides of square box has respectively a push pedal.
2. magnetic force according to claim 1 expands the begg appliance device, it is characterized in that said non-magnetic airtight rectangular box, difference limited location piece in the middle of the inwall of both sides, front and back, and left and right sides sidewall all has 3 holes of perforation.
3. magnetic force according to claim 1 expands the begg appliance device, it is characterized in that the relative high magnetic flux magnet of said two peers, takes full advantage of the magnet peer principle of repelling each other.
4. magnetic force according to claim 1 expands the begg appliance device, it is characterized in that said two slide blocks with three push rods, and two bars in front and back are actuating rods, and by promoting push pedal, and then power transmission nails on to tooth and plantation, reaches to expand and bends effect, and intermediate bar is release link.
5. magnetic force according to claim 1 expands the begg appliance device, it is characterized in that said about two push pedals, about to three tubulose through channel are arranged respectively, former and later two passages are with two sections profile of tooth inclined-planes, the push pedal outer end has preset the position of welding.
