Description

Technical Field

[0001] The invention relates to the technical field of oral medical instruments, in particular to a device for examining a temporomandibular joint and assisting in training and treating a mouth-opening movement. Background Art

[0002] After condylar fracture, joint surgery, or maxillofacial radiotherapy, there may be functional disorders such as limited mouth opening and limited mandibular function. Temporomandibular joint examination and rehabilitation training are crucial for the recovery of mandibular function. Generally speaking, the earlier the mouth opening function is restored after surgery, the better the long-term functional recovery will be. Currently, there are two main types of mouth opening training sticks and mouth openers.

[0003] The existing oral opening devices are mostly simple in structure and single in function. Most of them open the mouth through torsion springs or the elastic tension of their own materials. The size of the opening cannot be freely adjusted, which makes them inconvenient to use. Excessive opening can easily cause harm to patients. In addition, some patients will have muscle injuries after surgery and will have adverse symptoms such as difficulty opening their mouths. They need to use tools to train their mouths to open. Some existing opening devices mostly have fixed opening angles and need to be manually opened and closed for rehabilitation exercises. The size of the opening cannot be gradually adjusted according to the patient's recovery condition, nor can they automatically perform opening and closing cycle training, resulting in poor rehabilitation training effects. The placement height cannot be adjusted according to the patient's height, resulting in low comfort and convenience for patients when using the opening device. In addition, when the patient uses the opening device, the mouth will unconsciously secrete saliva, and the lack of an auxiliary drying device further affects the patient's comfort, which brings certain adverse effects to people's use process. To this end, we propose a temporomandibular joint examination and auxiliary mouth opening movement training and treatment device. Summary of the invention

[0038] How it works

[0039] The patient sits in front of the device, and first adjusts the height position of the disposable arc sponge liner 17 according to the patient's height. After starting the drive motor 7, the output shaft of the drive motor 7 is controlled to rotate in the direction of rotation, and the threaded screw 9 at the other end is driven to automatically rotate in the housing 3 through the bearing seat 10. The connecting nut seat 11 is driven by the meshing of the threaded screw 9 and the limiting effect of the positioning sliders 12 on both sides sliding on the guide rails 8, which can drive the replaceable oral automatic opening auxiliary device 14 to perform linear lifting and lowering motion on the threaded screw 9, so as to realize the disposable arc sponge liner 1 The automatic adjustment of the height of the disposable arc sponge liner 17 makes the disposable arc sponge liner 17 consistent with the oral position of the patient, so that the patient can maintain a comfortable posture for examination or treatment. After the new disposable arc sponge liner 17 is fixed by embedding the fixing groove 24 and the outer ring of the threaded connecting rod 23, the disposable arc sponge liner 17 is clamped and fixed on the threaded connecting rod 23 by using the disposable nut 25 and the threaded connecting rod 23 to complete the quick replacement and fixation of the disposable arc sponge liner 17, thereby improving the convenience of use of the device, improving the hygiene of use, avoiding infection, and the patient After the lips are placed on the disposable arc sponge liner 17, it can cover the entire upper and lower dental arches and the lining is soft. The fixing groove is designed to be an arc shape of the upper and lower teeth that is consistent with the disposable arc sponge liner 17, which improves the patient's comfort. After the electric push rod 19 is controlled to extend and retract through the control panel 4, the connecting arm 20 at the other end is driven to extend and retract in the guide sleeve 21, thereby driving the disposable arc sponge liner 17 on the threaded connecting rod 23 to automatically cycle closer and farther, thereby automatically assisting the patient's oral opening and closing, and the scale 22 on the connecting arm 20 can be controlled to adjust The PLC controller 38 can not only control the size of the opening and closing, but also control the time and frequency of the patient's oral opening. It is simple and convenient to use. The patient's treatment status can be recorded and uploaded through the cloud processor 5. Through intelligent interconnection, the patient can be reminded to perform opening training at a certain frequency every day to avoid forgetting. The mandibular movement trajectory recorder 37 can record the data of the lateral displacement of the opening and closing mouth and the data of the front and back displacement, and then draw a three-dimensional motion image and upload it to the cloud processor 5 for recording and retention, so as to record and study the patient's treatment process. When the patient uses the device to open and close the mouth and the mouth secretes saliva, the blowing head 33 is adjusted to face the inside of the patient's mouth through the adjustable hose 32. After setting the telescopic interval of the micro-electric push rod 34, the pressing plate 36 at the other end is driven to cyclically press the pressing airbag 30, so that the patient's oral cavity can be blown, the air circulation of the patient's oral cavity is improved, and the inside of the oral cavity is ensured to be dry to a certain extent. To a certain extent, the secretion of saliva in the patient's mouth during treatment is reduced, and the convenience of use is further improved.
