Description

Technical Field

[0001] The invention relates to the technical field of orthodontics, and in particular to an orthodontics traction force testing device. Background Art

[0002] In the past orthodontic treatment, doctors mainly relied on experience to judge the traction force. Due to the lack of precise quantitative methods, it is very easy to improperly control the traction force. When the traction force is too large, the patient will suffer unnecessary pain. In severe cases, it may even cause damage to the teeth and periodontal tissues, causing loose teeth, gum atrophy and other problems, affecting oral health. If the traction force is insufficient, the teeth move slowly, which will significantly prolong the treatment cycle, increase the patient's time and economic costs, and reduce the patient's satisfaction with orthodontic treatment.

[0003] From the perspective of measurement tools, the commonly used measurement methods in the past were relatively rough. For example, using only a simple pressure indicator can only roughly determine the force range and cannot provide accurate force value data. In complex orthodontic treatments, such as involving the movement of multiple teeth and traction in different directions, this rough measurement cannot meet the needs at all. It is difficult for doctors to formulate accurate personalized treatment plans based on these vague data, resulting in uneven treatment results.

[0004] In addition, traditional orthodontic treatment cannot monitor the traction force in real time. During the entire treatment process, the force on the teeth is in dynamic change, especially when wearing traction devices such as rubber bands. Factors such as the elasticity change of the rubber bands, the humidity and temperature in the patient's mouth, etc. will affect the actual traction effect. However, traditional methods cannot capture these changes in time. Doctors can only make adjustments based on the patient's subjective feelings and limited examinations during follow-up visits, which makes the treatment process somewhat blind and increases the risk of treatment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an orthodontic traction force testing device, which solves the problem that improper control of traction force is very likely to occur and the operation of adjusting the traction force is relatively cumbersome.

[0009] Preferably, the decomposition assembly comprises a decomposition frame, a decomposition shaft is installed inside the decomposition frame, and a force sensor is attached to the surface of the decomposition shaft.

[0010] Preferably, a retractable rod is installed inside the tension spring, one end of the retractable rod is fixedly connected to the moving frame, and the other end of the retractable rod is fixedly connected to the connecting arc plate.

[0011] Preferably, the cross section of the connecting arc plate is T-shaped.

[0013] Preferably, one end of the bottom of the clamping rod is connected to a boss, and the outer wall of the boss is rotatably connected to an auxiliary shaft.

[0015] The present invention provides an orthodontic traction force testing device, which has the following beneficial effects:

[0016] 1. The present invention has a convenient installation and disassembly design through the mobile installation mechanism of the device. When the patient's mouth is not adapted to the traction force of the rubber band, the installation seat can be quickly separated from the fixed seat by simply pressing the installation seat, and the rubber band can be quickly switched by using the cooperation of the card block, the sliding ladder block and the fixed ladder block, thereby avoiding the patient from bearing uncomfortable traction for a long time and significantly improving the comfort during wearing, thereby improving the patient's compliance with orthodontic treatment, reducing the risk of treatment interruption due to discomfort, and ensuring the smooth progress of orthodontic treatment.

[0018] 3. Through the decomposition and testing of the rubber band traction force, the present invention enables doctors to simulate the effects of different traction methods on teeth. By obtaining the force data after changing the direction and magnitude of the traction force according to the decomposition axis, combined with the actual oral conditions of the patient, doctors can more accurately design orthodontic treatment plans, optimize the traction path and strength, make tooth movement more in line with expectations, shorten the treatment cycle, improve the overall quality of orthodontic treatment, and bring better treatment effects to patients.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides an oral orthodontic traction force testing device, comprising an oral model 1, a tooth model 2 is connected to the inside of the oral model 1, a bracket 3 is attached to the surface of the tooth model 2, a plurality of brackets 3 are connected by an archwire 4, a movable installation mechanism 5 is installed on the surface of the archwire 4, which is used to connect and load the two ends of a rubber band 6, a slide groove 7 is opened on one side of the outer wall of the oral model 1, and a force decomposition mechanism 8 is slidably connected to the inside of the slide groove 7, which is used to decompose the traction force generated by the rubber band 6;

[0030] The mobile installation mechanism 5 includes a fixed seat 501, which is installed on the outer wall of the arch wire 4. One end of a short column 502 is installed on one side of the outer wall of the fixed seat 501, and the other end of the short column 502 is fixedly connected to a fixed ladder block 503. The outer wall of the short column 502 is slidably connected to a sliding ladder block 504. The outer wall of the short column 502 is slidably connected to a mounting seat 505. The top of the mounting seat 505 is fixedly connected to a hook 506, and the hook 506 is used to hang the rubber band 6. A T-shaped cavity 507 is opened inside the mounting seat 505. The two ends of the T-shaped cavity 507 are slidably connected to a clamping shaft 508 respectively. One end of the clamping shaft 508 is fixedly connected to a clamping block 509, and a spring 510 is installed on the outer wall of the clamping shaft 508.

[0031] The cross section of the short column 502 is rectangular;

[0032] Specifically, by pressing the mounting seat 505 to make it slide on the outer wall of the short column 502, the spring 510 shrinks and returns to its original state after the initial pressing of the mounting seat 505, so that the mounting seat 505 is engaged with the bottom of the fixed ladder block 503. At this time, the rubber band 6 can be hung inside the hook 506 connected to the mounting seat 505. The rubber band 6 forms traction on the tooth model 2 in a stretched state, thereby performing orthodontic treatment on the cavity. The mounting seat 505 is pressed again. At this time, the block 509 slides on the outer wall of the sliding ladder block 504, and because the sliding ladder block 504 is slidably connected to the short column 502, under the extrusion effect of the block 509, the sliding ladder block 504 slides to the top and fits with the bottom of the fixed ladder block 503, forming a symmetrical structure that allows the block 509 to slide out smoothly, thereby completing the rapid separation of the mounting seat 505 from the fixed seat 501, so as to facilitate rapid separation and switching when the oral cavity is not adapted to the traction force of the rubber band 6.

[0033] The force decomposition mechanism 8 includes a moving frame 801, a decomposition component is installed on one side of the outer wall of the moving frame 801, one end of a tension spring 802 is installed on one end of the moving frame 801, and a connecting arc plate 803 is installed on the other end of the tension spring 802. The connecting arc plate 803 is slidably connected to one side of the inner wall of the slide groove 7, a locking plate 804 is installed inside the moving frame 801, and a locking groove 805 is provided on one side of the outer wall of the locking plate 804, and evenly distributed rotating shafts 806 are installed inside the slide groove 7, and a clamping rod 807 is installed on one end of the rotating shaft 806.

[0034] The disassembly assembly includes a disassembly frame 808, a disassembly shaft 809 is installed inside the disassembly frame 808, and a force sensor 810 is attached to the surface of the disassembly shaft 809;

[0035] A retractable rod 811 is installed inside the tension spring 802, one end of the retractable rod 811 is fixedly connected to the moving frame 801, and the other end of the retractable rod 811 is fixedly connected to the connecting arc plate 803;

[0036] The cross section of the connecting arc plate 803 is T-shaped;

[0037] One end of the rotating shaft 806 is fixedly connected to one end of the spring 812, and the other end of the spring 812 is fixedly connected to one side of the inner wall of the slide groove 7;

[0038] A boss 813 is connected to one end of the bottom of the clamping rod 807, and an auxiliary shaft 814 is rotatably connected to the outer wall of the boss 813;

[0039] Specifically, the decomposition component can change the traction force generated by the rubber band 6 on the tooth model 2 by the decomposition shaft 809 contacting and pulling one side of the rubber band 6. By moving the decomposition shaft 809 at a suitable position of the oral model 1, the traction force generated by the rubber band 6 can be decomposed and changed. At the same time, the force sensor 810 on the surface of the decomposition shaft 809 can further accurately analyze the traction force generated by the rubber band 6. In addition, the sliding connection between the moving frame 801 and the slide groove 7 further improves the efficiency of the movement of the decomposition component. 1 changes the force decomposition effect of the decomposition shaft 809 on the traction force of the rubber band 6. At the same time, one end of the clamping rod 807 can slide inside the locking groove 805. When the clamping rod 807 moves to the inflection point of the locking groove 805, the moving frame 801 and the clamping rod 807 form a locking effect to fix the decomposition component. The decomposition shaft 809 can be conveniently moved and positioned by locking and separating the moving frame 801 and the clamping rod 807, so that the traction force inside the tooth model 2 can be conveniently tested and changed, so as to help the correct implementation of the traction force of oral orthodontics.

[0040] Working principle: First, when installing the rubber band 6, the mounting seat 505 is pressed to make it slide on the outer wall of the short column 502. During the pressing process, the spring 510 contracts. When the mounting seat 505 is released, the spring 510 returns to its original state, so that the mounting seat 505 is engaged at the bottom of the fixed ladder block 503. At this time, the rubber band 6 can be hung inside the hook 506 connected to the mounting seat 505. The rubber band 6 will generate traction in the stretched state, which is transmitted to the mounting seat 505 through the hook 506, and then transmitted to the tooth model 2 through the short column 502, the fixed seat 501, the archwire 4 and the bracket 3, so as to apply orthodontic force to the tooth model 2. When the oral cavity is not adapted to the traction force of the rubber band 6, the mounting seat 505 is pressed again, and the clamping block 509 slides on the outer wall of the sliding ladder block 504. Since the sliding ladder block 504 is slidingly connected with the short column 502, under the extrusion of the clamping block 509, the sliding ladder block 504 slides to the top and fits with the bottom of the fixed ladder block 503 to form a symmetrical structure, so that the clamping block 509 can slide out smoothly, thereby completing the rapid separation of the mounting seat 505 and the fixed seat 501, and realizing the rapid switching of the rubber band 6.

[0041] When the traction force generated by the rubber band 6 is decomposed and tested, the decomposition shaft 809 in the decomposition component contacts and pulls one side of the rubber band 6. By moving the decomposition shaft 809 at a suitable position of the oral model 1, the direction and magnitude of the traction force generated by the rubber band 6 on the tooth model 2 can be changed, thereby achieving the decomposition and change of the traction force. At the same time, the force sensor 810 on the surface of the decomposition shaft 809 can accurately measure the magnitude of the traction force generated by the rubber band 6 in real time and feed back the data to the user. The sliding connection between the moving frame 801 and the slide groove 7 enables the decomposition component to move conveniently in the slide groove 7, improves the efficiency of the movement of the decomposition component, and then can more flexibly change the force decomposition effect of the decomposition shaft 809 on the traction force of the rubber band 6. In addition, one end of the clamping rod 807 can slide inside the locking groove 805. When the clamping rod 807 moves to the inflection point of the locking groove 805, the moving frame 801 and the clamping rod 807 form a locking effect, thereby fixing the decomposition component and ensuring the stability of the position of the decomposition component during the test. By locking and separating the moving frame 801 and the clamping rod 807, the movement, positioning and fixing of the decomposition shaft 809 can be easily completed, so that the traction force inside the tooth model 2 can be conveniently tested and changed, which is conducive to the correct implementation of the traction force of oral orthodontics, provides accurate data support for clinical orthodontic treatment, and helps doctors to formulate more reasonable orthodontic plans. The force sensor 810 in the decomposition component is attached to the surface of the decomposition shaft 809, which can measure the traction force generated by the rubber band 6 in real time and accurately. Through this device, the doctor can obtain detailed force data and have a deep understanding of the force on the teeth at different traction stages, so as to provide individual It provides a scientific basis for the formulation of personalized treatment plans, accurately adjusts the traction force, improves the orthodontic treatment effect, and avoids tooth damage or prolonged treatment cycle due to improper traction force. By decomposing and testing the traction force of the rubber band 6, the doctor can simulate the impact of different traction methods on the teeth. According to the force data obtained after changing the direction and size of the traction force based on the decomposition axis 809, combined with the actual oral situation of the patient, the doctor can design the orthodontic treatment plan more accurately, optimize the traction path and strength, make the tooth movement more in line with expectations, shorten the treatment cycle, improve the overall quality of orthodontic treatment, and bring better treatment effects to patients.
