[0002] In the field of oral and maxillofacial surgery, many diseases and treatment methods can cause limited mouth opening. For example, temporomandibular joint disorder is one of the common diseases in oral and maxillofacial region. Its onset is related to various factors, such as malocclusion, mental stress, trauma, etc. Patients often have joint pain, click, and symptoms of limited mouth opening. According to statistics, about 20-30% of patients with temporomandibular joint disorder have obvious limited mouth opening, which seriously affects the basic life functions of patients such as eating and speaking.
[0003] Traditional mouth opening training methods mainly include manual assisted mouth opening and simple oral movement exercises. Manual assisted mouth opening is assisted by medical staff or the patient himself / herself using fingers to open the mouth. The fingers directly contact the inside of the mouth, and the fingers may carry various microorganisms such as bacteria and viruses, which can easily cause oral infection. Although simple oral movement exercises such as opening and closing the mouth can exercise the oral muscles to some extent, these movements may be difficult for patients with severe limited mouth opening to complete. Therefore, we introduce a new mouth opening training device for oral cavity and maxillofacial region. SUMMARY

[0027] Please see Figures 1-4 This utility model provides a technical solution:
[0028] An oral and maxillofacial mouth-opening training device includes a connecting cylinder 1. The upper and lower inner parts of the connecting cylinder 1 are provided with movable grooves 2. The upper front side, the lower front side, the upper rear side, and the lower rear side of the outer surface of the connecting cylinder 1 are provided with connecting grooves 3. The upper left side, the lower left side, the upper right side, and the lower right side of the outer surface of the connecting cylinder 1 are provided with damping grooves 4. The inner walls of the two movable grooves 2 are fixedly connected to auxiliary mechanisms 5. The rear ends of the two auxiliary mechanisms 5 are fixedly connected to connecting blocks 6. The back sides of the two connecting blocks 6 are fixedly connected to adjusting mechanisms 7.
[0029] In this embodiment, the auxiliary mechanism 5 includes a movable block 51. Damping rods 52 are fixedly connected to the left and right sides of the outer surface of the movable block 51. A pinch rod 53 is fixedly connected to the front of the outer surface of the movable block 51. A spring 54 is fixedly connected to the lower end of the movable block 51. A connecting rod 55 is fixedly connected to the rear of the outer surface of the movable block 51. The movable block 51 is located inside the corresponding movable groove 2, and the outer surface of the movable block 51 is movably connected to the inner wall of the corresponding movable groove 2. The two damping rods 52 are slidably connected to the two corresponding damping grooves 4 respectively. The end of the spring 54 away from the movable block 51 is fixedly connected to the inner wall of the corresponding movable groove 2. The pinch rod 53 is movably connected to the corresponding front connecting groove 3. The connecting rod 55 is movably connected to the corresponding rear connecting groove 3, and the rear end of the connecting rod 55 is fixedly connected to the connecting block 6.
[0030] The above method allows patients with mild mouth opening limitation to close their mouths voluntarily, bringing the two dental trays 75 closer together, compressing the two springs 54. Then, by relaxing the teeth, the springs 54 return to their original position, allowing the two dental trays 75 to move away from each other, thus enabling the patient to open their mouth automatically. This repetitive operation achieves good training results. For patients with severe mouth opening limitation, medical staff or family members can manually squeeze the two levers 53. When the levers 53 move closer together, the springs 54 are compressed, bringing the two dental trays 75 closer together, allowing the patient to close their mouth. When the levers move away from each other, the springs 54 return to their original position, allowing the two dental trays 75 to move away from each other, thus enabling the patient to open their mouth.
[0031] In this embodiment, the adjustment mechanism 7 includes a universal seat 71 and a universal ball 72. A first connecting post 73 is fixedly connected to the lower part of the outer surface of the universal seat 71. A second connecting post 74 is fixedly connected to the upper part of the outer surface of the universal ball 72. A mouth bracket 75 is fixedly connected to the upper end of the second connecting post 74. A mouth pad 76 is fixedly connected to the inner surface of the mouth bracket 75. The lower end of the first connecting post 73 is fixedly connected to the connecting block 6. The universal ball 72 is movably connected to the universal seat 71.
[0032] The above method involves placing the upper dental tray 75 on the upper teeth and the lower dental tray 75 on the lower teeth, ensuring that both dental pads 76 are in close contact with the upper and lower teeth. The angle of the two dental trays 75 can be adjusted by the movement of the universal ball 72 within the universal seat 71. This angle adjustment allows the patient's teeth to be quickly inserted into the dental trays 75, making the training device easy to wear.
[0033] It should be noted that this utility model is a mouth-opening trainer for the oral and maxillofacial region. During use, the upper dental tray 75 is placed on the upper teeth, and the lower dental tray 75 is placed on the lower teeth, ensuring that the two dental pads 76 are in close contact with the upper and lower teeth respectively. This close fit design reduces the movement of the trainer in the mouth, improving patient comfort. Furthermore, the dental trays 75 and dental pads 76 are adjustable in angle via the flexible movement of the universal ball 72 within the universal seat 71. This angle adjustment function allows the patient's teeth to easily fit into the dental trays 75, simplifying the wearing process. When the trainer is worn inside the mouth, patients with mild mouth-opening limitations can voluntarily close their mouths, allowing the two dental trays 75 to interact. Approaching the teeth compresses the two springs 54, then releasing the teeth allows the springs 54 to return to their original state, pushing the two dental trays 75 away from each other, thus achieving automatic mouth opening. Repeating this process can achieve good training results. For patients with more severe mouth opening limitations, medical staff or family members can manually pinch the two levers 53 to assist training. When the two levers 53 approach each other, they compress the two springs 54, bringing the two dental trays 75 closer together, helping the patient close their mouth. When the two levers 53 move away from each other, the springs 54 return to their original state, pushing the two dental trays 75 away from each other, allowing the patient to open their mouth. Repeating this process, whether for voluntary or assisted mouth opening, ensures the repeatability and regularity of the training, ultimately achieving a good training effect to improve mouth opening limitations.
