Description

Technical Field

[0001] This invention belongs to the field of medical devices, specifically relating to a temporomandibular joint physiotherapy device. Background Technology

[0002] Temporomandibular joint dysfunction (TMJ) is a common clinical condition, ranking fourth among oral health epidemics affecting human health. TMJ syndrome refers to a syndrome characterized by a range of symptoms including pain, clicking, muscle soreness, weakness, limited mouth opening, and impaired temporomandibular joint function in the temporomandibular joint region. Some cases experience recurrent, prolonged, and persistent symptoms, severely impacting masticatory muscles and speech function. From a modern medical perspective, the causes of this disease are complex and remain unclear; currently, it is believed to be related to factors such as emotional instability, physical weakness, disordered dental occlusion, and trauma. These factors affect the normal structure of the temporomandibular joint or impair the coordinated movement of the muscles and ligaments attached to the joint structures. Existing treatment methods mainly include light, electricity, acupuncture, injection, and physical therapy. For example, there are treatments such as super laser therapy, temporomandibular joint arthroscopy, acupuncture combined with shortwave diathermy, super laser irradiation combined with local injection of the temporomandibular joint, and bloodletting with warm needle therapy. Each of these methods has its advantages and disadvantages and is suitable for different groups of people. At the same time, the above treatments also require the use of traction devices to exercise the patient's bite. However, the current temporomandibular joint traction devices cannot pre-open the gap of the patient's temporomandibular joint, so that the temporomandibular joint cannot open the patient's mouth at a large angle.

[0003] This invention addresses the lack of devices in the existing technology that can meet the physical therapy needs of patients with temporomandibular joint dysfunction by providing a temporomandibular joint physical therapy device. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the following detailed description of preferred embodiments is provided in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4This invention provides a temporomandibular joint (TMJ) physiotherapy device, comprising: multiple occlusal molds configured according to different oral opening degrees of patients; and a physiotherapy device that can be worn on the patient's head. The device is characterized by having a head frame that can be worn on the patient's head and a mandibular frame hinged to the head frame; both the head frame and the mandibular frame can be extended and adjusted according to differences in the patient's face; slots are provided on both sides of the mandibular frame corresponding to the temporomandibular joints on both sides of the patient; multiple physiotherapy mechanisms with different physical treatment methods are provided, and each physiotherapy mechanism is detachably connected to a slot; a battery assembly with adjustable release voltage is provided within the slot, and the battery assembly has multiple power supply interfaces of different specifications, with each power supply interface having a physiotherapy mechanism adapted to it.

[0032] It should be noted that: before use, a suitable occlusal mold should be placed in the patient's mouth, and then the head frame and mandibular frame should be adjusted to make the physiotherapy device stably set on the patient's head; a physiotherapy device suitable for the patient's physiotherapy method should be selected and connected to the slot at the temporomandibular joint, and the battery assembly in the slot contains multiple power supply interfaces to meet the power supply needs of different physiotherapy devices, thereby meeting the patient's physiotherapy needs, so that the patient can receive reasonable physical therapy for the mandibular joint while performing occlusal training.

[0033] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 The head frame includes a plate with a cavity and two elastic plates that slide along both sides of the cavity respectively; a grid is provided between the elastic plates and the cavity of the plate;

[0034] The head frame has curved plates on both sides that are perpendicular to the head frame; a locking nut that penetrates the head frame is provided at the top of the head frame, and a pressure plate is provided at one end of the locking nut; the chin frame has the same configuration as the head frame.

[0035] It should be noted that: during use, the sliding plates on both sides of the cavity are slid by pulling the plate simultaneously, thereby meeting the telescopic adjustment needs of the head frame and the jaw frame; at the same time, the grid is set to increase the damping between the elastic plate and the plate cavity, so that it only starts to slide when manually pulled; the curved plate setting can provide the physiotherapy device with a better fixation effect.

[0036] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 Earmuffs are provided for both sides of the patient's ears, and the two ends of the rod are connected to the head frame and the earmuffs respectively.

[0037] It should be noted that when using the device, the placement position of the physiotherapy device should be determined by the ear cups to ensure that the slot on the jaw support is aligned with the patient's temporomandibular joint.

[0038] In an embodiment of the present invention, please refer to Figure 3 The physiotherapy device includes an electric heating pad for applying heat, a micro pulse device for pulse stimulation, an electric massage head for physical massage, and a micro laser device for laser stimulation; the electric heating pad, the micro pulse device, the electric massage head, and the micro laser device are all equipped with electrode plugs that can be electrically connected to a power supply interface, and an elastic pressure plate for mounting a square plate is provided in the slot; the above configuration allows for detachable connection between the above physiotherapy devices and the slot;

The information processing module has a signal input port and a signal output port. The signal input port can input the coded signal from the information input module, and the signal output port can output the processed coded signal from the signal processing module to the power supply interface selection module, the battery control module, and the voice reminder module.

[0043] It should be noted that when the miniature disk rotates once during use, the power supply interface below the through hole on the first partition will be replaced.

[0044] The working principle of the temporomandibular joint physiotherapy device provided by this invention is as follows: The doctor prepares an electronic medical record memory card based on the patient's condition, and simultaneously prepares an occlusal mold using 3D printing based on the patient's oral opening degree; the electronic medical record memory card can be input via a cloud input module to record the usage duration, intensity, sequence, and cycle of each physiotherapy institution; the patient wears the physiotherapy device on their head, and the lengths of the head frame and mandibular frame are adjusted to ensure the physiotherapy device is stably mounted on the patient's head, and the slot of the mandibular frame is aligned with the patient's temporomandibular joint; the cloud input module records the usage duration, intensity, sequence, and cycle of each physiotherapy institution.
