Abstract
Description
Technical Field
[0001] The present invention relates to an induction type temporomandibular joint movement device. Background Art
[0002] Temporomandibular joint dysfunction syndrome is one of the common diseases clinically. Temporomandibular joint dysfunction syndrome refers to a series of symptoms such as pain, clicking, muscle soreness, weakness, limited mouth opening, and temporomandibular joint dysfunction in the temporomandibular joint area. Some cases have repeated attacks, protracted courses, and are difficult to cure, seriously affecting the masticatory muscles and language functions. From the perspective of modern medicine, the causes of this disease are relatively complex and not yet clear. It is currently considered to be related to factors such as unstable emotions, weak constitution, disordered tooth occlusion relationships, and trauma. These factors affect the normal structure of the mandibular joint or cause disorders in the coordinated movements of the muscles and ligaments attached to the joint structure.
[0003] Existing treatment methods include: light, electricity, acupuncture, injection, physical therapy, etc.
[0004] For example: super laser therapy instruments, temporomandibular arthroscopes, acupuncture combined with ultrashort wave therapy, super laser irradiation combined with local injection therapy of the temporomandibular joint, bloodletting and warming acupuncture therapy, etc. Each treatment method has its own advantages and deficiencies and is suitable for different populations.
[0005] Another physical therapy method mainly relies on a traction device and the manual pressing of a therapist. It is convenient, safe, has a wide adaptability range, low medical costs, high cure rates, and high patient acceptance. The patent with the patent number ZL201420629753.4 discloses a temporomandibular joint opening exerciser. Patents with the patent numbers WO2012024828A1, AU2013334877A1, CA2663354A1, KR20120033385A, and RU2440063C1 also disclose similar temporomandibular joint movement devices. However, when clinical patients have limited temporomandibular joint stiffness and mobility, the physical traction device treatment mode is a single vertical slow opening of the mouth, forcing the temporomandibular joint to slowly rotate for a period of time and then return to its original state, with several consecutive treatment cycles over several days or weeks. However, when treating, doctors cannot directly obtain the change information of the temporomandibular joint movement device and the force information applied to the patient, which may lead to an increase in the patient's pain or an unclear treatment effect. That is, doctors need to manually adjust the mouth opening distance and there is no force feedback for cooperative diagnosis. Therefore, there are defects such as insufficient comfort and lack of compliance in current clinical applications. Summary of the Invention
[0006] The object of the present invention is to overcome the defects of the prior art and provide an induction type temporomandibular joint movement device, which is small in appearance, convenient to carry, and patients can treat themselves at any time, being safe and comfortable.

[0025] In order to enable those skilled in the art of this technology to better understand the technical solution of the present invention, the following will describe its detailed implementation manner in conjunction with the accompanying drawings:
[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the best embodiment of the present invention, an induction type temporomandibular joint activity device, includes a housing 14, a display screen 13, a opening and closing mechanism, and a laser sensor 17. The housing 14 is trapezoidal in shape, and the display screen 13 is embedded on the front surface of the housing 14; a semi-circular groove 20 is provided at the front end of the bottom of the housing 14, and the opening and closing mechanism is arranged in the semi-circular groove 20; the opening and closing mechanism includes a porous air disc 10 and a polymer film sheet 15. The porous air disc 10 is composed of a stainless steel tube, a plurality of air outlet holes opened on the tube wall of the stainless steel tube, and a polymer porous fiber 16 filled in the stainless steel tube. The plurality of air outlet holes are uniformly distributed on the tube wall of the stainless steel tube; the polymer film sheet 15 covers the outside of the porous air disc 10; the laser sensor 17 is arranged on the front surface of the housing 14, and the laser sensor 17 is located above the display screen 13.
[0027] A pressure sensor 11 and a drive motor 2 for supplying air to the porous air disc 10 are arranged in the housing 14.
[0028] On the back of the display screen 13, a main control board 12 is provided; the driving motor 2, the laser sensor 17 and the pressure sensor 11 are respectively connected to the main control board 12. Upper and lower buttons for adjusting a preset opening distance are provided on the display screen 13.
[0029] For the induction type temporomandibular joint movement device of the present invention, the preset opening distance is set through the upper and lower buttons. The main control board 12 sends a working signal to the driving motor 2 according to the preset opening distance. The driving motor 2 operates to convey air to supply air to the porous air disc 10, and the polymer porous fiber 16 expands to drive the height of the polymer thin film 15 to increase; the laser sensor 17 measures the actual height of the polymer thin film 18 in real time to obtain the actual opening distance, and feeds back the actual opening distance to the main control board 12; the pressure sensor 11 senses the air pressure value of the air supplied by the driving motor 2 to the porous air disc 10, and sends the air pressure value data to the main control board 12. The main control board 12 sends the actual opening distance and the air pressure value data to the display screen 13 for display. Since the laser sensor 17 is arranged above the display screen 13, the influence of other devices on the information obtained by the laser sensor 17 can be avoided, and thus the laser sensor 17 can obtain more accurate information.
[0030] For the induction type temporomandibular joint movement device of the present invention, in the case where the patient is extremely uncomfortable or needs to urgently change the treatment method, long-press any point on the display screen 13 to start, respectively adjust the upper and lower buttons on the display screen 13 to the initial position, and then let the patient bite the polymer thin film 15. At this time, if you want to open the mouth wider, you can adjust the upper button on the display screen 13 to set the opening distance. The opening distance between the temporomandibular joints can be opened up to about 45 mm at most. The main control board 12 controls the driving motor 2 to convey air to supply air to the porous air disc 10. The polymer porous fiber 16 expands to drive the height of the polymer thin film 15 to increase, thereby adjusting the actual opening distance. The opening distance (unit: MM) and force (unit: N) information of the whole process are displayed on the display screen 13 in real time. While easily opening the stiff mouth of the patient, the doctor can record the opening distance and torque change value during the stretching treatment process, and can more specifically understand the relevant information of the patient, and the treatment is more in line with the actual situation.
[0031] During the use of the induction type temporomandibular joint movement device of the present invention:
[0032] (1) Improve the original simple physical therapy, add sensing devices, such as opening distance detection and force detection. Doctors can, through the obtained sensing information, enable the patient to receive treatment in a comfortable state, eliminate the patient's tension and fear, and improve the opening range and flexibility of the mouth under painless treatment. By creating permanent, non-invasive tissue elongation and remodeling, the range of movement rebound effect can be almost eliminated;
[0033] (2) Drive the mouth opening treatment through the drive motor 2 to achieve the function of automatically helping the temporomandibular joint head to move downward and forward, widen the gap between the temporomandibular joints, and make it easier to open the mouth wider.
[0034] (3) In addition, by monitoring and guiding the patient to use the device in real time, safer and more effective mouth opening improvement can be achieved, while also reducing the workload of the therapist and minimizing the therapist's reliance on manual skills, which is suitable for the popularization and application of this technology.
[0035] In summary, the induction type temporomandibular joint activity device of the present invention is small in shape, convenient to carry, and patients can perform self-treatment at any time, which is safe and comfortable.
[0036] Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as within the scope of the spirit of the present invention, changes and modifications to the above embodiments will fall within the scope of the claims of the present invention.
