Description

Technical Field

[0001] This invention relates to the field of oral treatment technology, specifically to a connecting force application device for orthodontics. Background Technology

[0002] The core of orthodontics is a comprehensive treatment that improves function and aesthetics by adjusting the alignment and occlusion of teeth. To achieve better orthodontic results, doctors use various auxiliary devices during the orthodontic process. Some cases require extraoral traction. There are various types of extraoral traction devices, such as combined traction devices, mandibular traction devices, high traction devices, and anterior traction devices. During treatment, it is necessary to have regular check-ups at the hospital to monitor the orthodontic progress.

[0003] The patent application number CN202110051420.2 mentions "a protective oral retractor for orthodontic testing". It is designed by setting up an expansion device 1, which includes a mounting plate and a tooth plate. A fixing plate is also provided and connected to a fixing shaft and an adjusting plate in the expansion device 2. When the expansion device 1 is used to expand the patient's teeth, the medical staff guides the patient to bite their teeth into the grooves on the tooth plates. This solves the problems of existing oral retractors for orthodontic testing, which cover a large area of ​​the patient's teeth, making it difficult for doctors to observe the condition of the patient's teeth. Furthermore, most existing oral retractors for orthodontic testing do not have a protective function, and they are inconvenient to disassemble, clean and disinfect after use.

[0004] However, during the use of the above-mentioned device, it is necessary to go to the hospital frequently to check the orthodontic condition. Each time the mouth opens, it is necessary to use the mouth opener for examination. After the examination, the traction device is then worn. In addition, it is inconvenient to operate. It is also necessary to hold the mouth opener to prevent it from falling off or causing additional burden and discomfort to the patient due to the weight of the mouth opener. Furthermore, the rubber band connects the inside and outside, which causes the mouth to not close tightly, and saliva is easy to flow out. Summary of the Invention

The positioning screw 221 is rotated to fix it. The patient opens his mouth and the rubber anti-dislodgement clip 226 is first attached to the corner of the mouth. Then the opening clip 225 is inserted into both sides of the mouth. Then the pull screw 223 is rotated. Since the threads at both ends of the pull screw 223 are turned in opposite directions, the mouth can be pulled open for testing. There is no need to hold the fixed mouth opener. The mouth opening is more convenient and easier to diagnose. After the diagnosis is completed, the installation block 220 can be removed and the rubber band 411 can be reinstalled for traction, reducing the number of times the traction device is removed and making diagnosis and treatment more convenient. When connecting the rubber band 411, tap the top seal 413, puncture the disinfection bag 412 at the top, take out the cotton swab 410, place the cotton swab 410 on the top surface of the ruptured disinfection bag 412, and disinfect the rubber band 411 on the top surface of the cotton swab 410 after the cotton swab 410 is soaked in hydrogen peroxide. There is no need to worry about the rubber band 411 being contaminated, and the disinfection is quick and convenient. It is also convenient to find the rubber band 411 when needed, avoid losing it, and make it easier to use. Remove the protective sleeve 405. Connect one end of the rubber band 411 to the hook rod 404 and the other end to the dental brace inside the mouth. Then put the protective sleeve 405 back. The rubber band 411 is at the insertion outlet 406. The magnetic edge 407 is attached to the top surface of the iron block 403 to fix it in place, so as to prevent the rubber band 411 from falling off the hook rod 404 and causing a rebound. This better fixes the rubber band 411. The inner side of the forehead pad 304 fits against the forehead, and the flexible copper sheet 306 is close to the forehead and separated by the silicone pad strip 307. The flexible copper sheet 306 conducts heat to avoid stuffiness and discomfort when wearing the pad. The inflatable pad 301 is attached to both sides of the inflatable pad 301 with Velcro by the sponge pad 302. The inflatable pad 301 is inflated and inflated. When lying down or turning over, the inflatable pad 301 will protect the sides of the head and prevent the middle block 1, inner frame 204 and outer frame 205 from squeezing the sides of the face and causing discomfort, thus improving wearing comfort. After wrapping the absorbent cloth 209 around the rotating shaft 208, insert it into the fixing inner thread 216. One end of the rotating shaft 208 is embedded into the fixing rotating hole 215, and the other end passes through the movable rotating hole 218. The limiting end seal 217 is connected to the fixing inner thread 216 through the threaded connection. Move the moving block 219 to fix the rotating shaft 208. Then pull the wrapped absorbent cloth 209 and tear it along the cutting groove 212. Pass the torn strip through the gap between the rubber bands 411 and temporarily stick it to the mouth with the adhesive strip 210. The absorbent cloth 209 absorbs the saliva that flows out of the mouth when wearing the device at night. The mouth is protected by the absorbent cloth 209 and the protective film 211. Even if the rubber band 411 breaks and rebounds to hit the mouth, the isolation and cushioning of the absorbent cloth 209 and the protective film 211 can reduce the pain and avoid the shock and pain of being hit when it breaks, further improving the convenience of use. The adjustable force application component 2 allows for easy size adjustment to suit patients with different face shapes and to adjust to the appropriate force, improving wearing comfort and orthodontic effect, and preventing the elastic band 411 from breaking and rebounding to hit the face. The top protection component 3 improves comfort during long-term wear. The middle adjustment component 4 prevents the elastic band 411 from falling off and rebounding to hit the face. Together with the adjustable force application component 2, it better prevents problems with the elastic band 411. The three components work together to further improve wearing comfort and orthodontic effect.
