Description

Technical Field

[0001] This invention relates to the field of rehabilitation training technology, and more specifically to a mandibular movement rehabilitation training system. Background Technology

[0002] Patients may experience varying degrees of mandibular movement restriction after temporomandibular joint surgery, oral and maxillofacial infections, oral and maxillofacial tumor surgery or radiotherapy, or oral and maxillofacial trauma. Their natural mandibular range of motion may not reach its pre-treatment state. To restore mandibular function, devices are needed to assist patients in performing mandibular movement training. Existing mandibular movement training equipment can only achieve vertical opening and closing movements of the mandible, but cannot achieve mandibular protrusion or lateral movements. Furthermore, most existing mandibular movement training devices are handheld mechanical structures, requiring patients to control the range of motion and pressure on the mandible during training. The distance and intensity of each training session are subjectively controlled by the patient, lacking stability and systematic approach. Clinically, training programs need to be continuously adjusted according to the patient's recovery status. However, patients often find it difficult to accurately and promptly monitor and provide feedback on their training time and intensity, leading to an inability to accurately assess their training progress and reducing the efficiency of rehabilitation training. Therefore, developing a new mandibular movement rehabilitation training system based on existing equipment to overcome these problems is a direction that those skilled in the art need to research.

[0052] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0053] Example 1, please refer to Figure 1-2 :

[0054] A mandibular movement rehabilitation training system includes: a training execution module 100, a data acquisition module 200, a data processing module 300, and a data interaction module 400. The training execution module 100 executes mandibular movement rehabilitation training movements, including at least one of mouth opening, mandibular protrusion, and mandibular lateralization. The data acquisition module 200 collects training data generated by the training execution module 100 in real time during operation, including mandibular displacement data and mandibular force data for each training movement. The data processing module 300 processes the training data and generates prompt information. The data processing module 300 includes a text-to-image conversion unit, which converts the training data into text-to-image data to generate training data text-to-image prompts. The data interaction module 400 includes an output unit, which displays the prompt information.

[0055] In practice, its working process is as follows:

[0056] The patient first operates the training execution module 100 to perform mandibular movement rehabilitation exercises. During this process, the data acquisition module 200 collects the patient's training data (mainly mandibular displacement and force data in each exercise). This training data is transmitted in real-time from the data acquisition module 200 to the data processing module 300. The data processing module 300 converts the training data into text or graphics that can be read by the patient through a text-to-image conversion unit. Simultaneously, the data interaction module 400 reads the data from the data processing module 300 in real-time and displays the training data as text and images to the patient in real-time through the output unit. By adopting the above technical solution, during the rehabilitation training, the patient can observe whether their training movements have reached the preset standards in real-time by observing the output unit of the data interaction module 400, and adjust their training methods accordingly, thereby improving the subsequent training effect.

[0057] In this example, the data acquisition device includes at least a distance sensor and a pressure sensor 211. The distance sensor is used to collect maxillary and mandibular displacement data during various training movements in the mandibular movement rehabilitation training, such as mouth opening, mandibular protrusion, and mandibular lateralization. The pressure sensor 211 is used to collect maxillary and mandibular force data during each training movement in the mandibular movement rehabilitation training. The output unit of the data interaction module 400 (generally using a device such as an LCD screen) displays the displacement and force data of the maxillary and mandibular structures in real time. The data processing module 300 can be a local machine or a remote mobile communication terminal. When a remote control terminal is used as the data processing module 300, it interacts with the data acquisition module 200 and the data interaction module 400 via wired or wireless (such as Bluetooth) communication methods. The data interaction module 400 can be configured as a patient user terminal for reading prompts (e.g., including a display screen) or a doctor user terminal for reading prompts by medical staff, both with at least graphic display capabilities.

[0058] In this example, the data interaction module 400 further includes an input unit for inputting operation information, including action category information and training round information. By adopting this technical solution, during training, the patient can input the currently executed training action category and training round through the input unit, thereby achieving round-based and category-based classification of training data. In practice, the patient can operate the input unit by touching electronic icons displayed on the touchscreen, or by using a keyboard or mouse to click on preset menus. Taking touchscreen operation as an example: "Start" and "End" icons, as well as three action icons—"Open Mouth," "Jaw Protrusion," and "Jaw Lateralization"—can be programmed on the touchscreen interface. The patient clicks the "Start" icon, then selects an action icon (such as the "Open Mouth" icon), and the data processing module 300 treats the subsequently input training data as training data for the "Open Mouth" action, until the patient clicks the next action icon—either "Jaw Protrusion" or "Jaw Lateralization." After completing all training, the patient clicks the "End" icon. The data processing module 300 then considers the training data collected between clicking "Start" and "End" as training data obtained in the same training round and performs data clustering. The above operation input methods are all functions that programmers can implement based on existing programming knowledge, and their specific implementation processes will not be elaborated here.

[0059] Furthermore, the input unit is also used to input a training plan as prompting information.

[0060] This approach allows for the creation of corresponding training plans based on the patient's current treatment stage. Patients can then access the training plan for the current round of treatment through the data interaction module 400, enabling targeted rehabilitation training. Furthermore, patients can actively modify and update their training plans based on their experiences during training (e.g., significant facial soreness after training indicates the inability to continue with higher intensity training, while the absence of soreness allows for proactive increases in training intensity). This process accelerates the rehabilitation process.

[0061] In this example: the data processing module 300 further includes:

[0062] An action timing unit is used to obtain the duration of each training action;

[0063] The data statistics unit is used to count the number of times various training actions are executed within a preset time period and generate statistical data as prompt information.

[0064] A data storage unit, wherein the data storage unit is used to store the training data and the statistical data;

[0065] By adopting this approach, the duration of each training movement during rehabilitation can be statistically analyzed to measure whether the movement has achieved its intended muscle-training effect. Simultaneously, by recording the number of repetitions of each movement, it can be determined whether the patient's exercise volume in a single training session reaches the preset minimum limit, and whether the cumulative exercise volume over a period of time (e.g., 24 hours) is sufficient to achieve muscle memory formation. During each rehabilitation training session, the patient does not need to focus on counting each movement and can track their completed training volume by reading data from the data interaction module 400, thus preventing the patient from performing too many or too few movements in a single training session. Furthermore, this helps the patient concentrate during rehabilitation training, improving the training effect.

[0066] In this example: the data processing module 300 further includes:

[0067] An alarm unit is used to generate an alarm message as a prompt when any of the statistical data and the training data triggers a preset condition.

[0068] The following are some alarm triggering conditions used in practice:

[0069] Triggering condition 1: A relative displacement of the upper and lower jaws >40 mm during mouth opening, >10 mm during mandibular protrusion, or >10 mm during mandibular lateralization. Under these conditions, the relative displacement of the upper and lower jaws has reached the upper limit of the average relative displacement data for healthy individuals during mouth opening, mandibular protrusion, and mandibular lateralization. If a patient performs such an excessive range of motion during training, it will cause training injury.

[0070] Triggering condition 2: The duration of a single round of rehabilitation training is less than 10 minutes, or the total duration of rehabilitation training within 24 hours is less than 60 minutes. In this case, the patient's training time in a single round of rehabilitation training or the cumulative training time within a day is insufficient, and the overall training volume cannot achieve the therapeutic goal of fully exercising the relative displacement of the upper and lower jaws.

[0071] Triggering condition 3: When the mouth opening, forward protrusion, and left and right lateral movements are at their maximum, the maximum range of motion is maintained for less than 30 seconds, or the relative displacement of the upper and lower jaws is less than the relative displacement value of the upper and lower jaws specified in the current training plan; under these circumstances, the patient's single training movement fails to meet the standard and cannot achieve the training effect corresponding to that training movement.

[0072] Triggering conditions 1 and 2 are determined by logical operations based on the training data (i.e., the displacement data and force data of the upper and lower jaws in each training action) to determine whether they are triggered. Triggering condition 3 is determined by reading the computer's internal clock through the alarm unit, calculating the total training time accumulated over 24 hours, and the continuous training time of each round of rehabilitation training, and then performing logical operations to determine whether it is triggered.

[0073] By adopting this approach, the system automatically alerts patients when their current training movements fail to meet the standards. This eliminates the need for patients to constantly monitor the data interaction module 400 during rehabilitation training. Instead, patients only need to query the data interaction module 400 upon receiving an alarm notification to determine in which aspects their training movements have fallen short. This further focuses the patient's attention during rehabilitation training, ensuring training efficiency. In practice, the alarm notification can be implemented using at least one of the following methods: audible and visual alarm, image and text alarm, or SMS alarm.

[0074] Application Example 1:

[0075] The previous study included 215 patients diagnosed with temporomandibular joint disc displacement and who underwent temporomandibular joint disc displacement surgery. They were followed up for 6 months. With a mouth opening of ≥37 mm as the standard, 86 patients achieved the target mouth opening at 6 months.

[0076] We analyzed the mouth opening of all patients who achieved the target for mouth opening rehabilitation at 1 month and 3 months postoperatively. Based on the bootstrap method, the mean mouth opening at 1 month postoperatively was estimated to be 31.86±1.26 mm with a 95% confidence interval [29.50, 34.42], and the mean mouth opening at 3 months postoperatively was estimated to be 36.62±1.07 mm with a 95% confidence interval [34.41, 38.56].

[0077] Based on the above estimation results, the lower limit of the 95% confidence interval, 29 mm, is taken as the target value for the relative displacement of the upper and lower jaws (i.e., mouth opening) during mouth opening exercises in the mandibular motor rehabilitation training 1 month after surgery; the lower limit of the 95% confidence interval, 34 mm, is taken as the target value for the relative displacement of the upper and lower jaws (i.e., mouth opening) during mouth opening exercises in the mandibular motor rehabilitation training 3 months after surgery.

[0078] The patient began mandibular motor rehabilitation training one week after surgery:

[0079] 1. Mouth Opening Exercise Training: Based on the patient's maximum mouth opening before starting training, with 29 mm as the target value for one month post-surgery, break down the weekly rehabilitation training target values ​​to be achieved, and calculate the target training range to be achieved each week within one month post-surgery. (For example, if the patient's maximum mouth opening before starting training is 25 mm, then the target values ​​to be achieved each week within one month are 25 mm, 27 mm, 27 mm, and 29 mm respectively.) Based on the patient's initial mouth opening value and considering their own feelings, increase the range by 2 mm each time. If the patient does not feel soreness while performing rehabilitation training at the current range, increase the relative displacement value of the upper and lower jaws in the mouth opening training by 2 mm, and so on, until the rehabilitation target for one month post-surgery is reached. If the target value is reached ahead of schedule, the next stage of the rehabilitation training plan can be implemented earlier.

[0080] The training plan, spanning 8 weeks from the 2nd to the 3rd month post-surgery, uses the patient's maximum mouth opening achieved one month post-surgery as the starting point and a target value of 34 mm as the calculation (e.g., if the patient achieves a maximum mouth opening of 29 mm at one month, the target values ​​for each week over the next 3 months are 29 mm, 29 mm, 31 mm, 31 mm, 31 mm, 33 mm, 33 mm, and 34 mm, respectively). After three months of training, the rules for increasing the range of mouth opening are the same as those for the first month post-surgery, ultimately aiming to achieve a mouth opening ≥37 mm by the 6th month post-surgery.

[0081] 1. Mandibular protrusion and lateral mandibular movement training: Based on the patient's initial range of motion, increase the range by 1 mm each time. If the patient experiences no soreness during rehabilitation training at the current range, increase the range by 1 mm and begin training for the new rehabilitation target value. The ultimate goal is to achieve a maximum lateral and mandibular protrusion range of >7 mm at 6 months post-surgery. (For example, if the patient's maximum mandibular protrusion and lateral movement range is 0 mm one week post-surgery, take 4 mm as the target value for mandibular protrusion and lateral movement within one month post-surgery, then break it down into weekly target values ​​of 1 mm, 2 mm, 3 mm, and 4 mm.) If the patient experiences no soreness during rehabilitation training, the patient can set a 1 mm increase as the next rehabilitation training range value. Continue this pattern of rehabilitation training until the goal of achieving a maximum lateral and mandibular protrusion range of >7 mm at 6 months post-surgery is reached. Later, to determine the maximum range of motion for mouth opening training at 1 month and 3 months post-surgery, the sample size can be increased, and raw data collected using the rehabilitation training system can be used for further adjustments. In addition, the training plan can also be generated by medical staff who, after reviewing the data feedback, specify it based on their professional experience and write it directly into the data processing module 300 through the writing unit, and then display the feedback through the data interaction module 400.

[0082] In this example, the data processing module 300 may further include an identity verification unit, which verifies the patient identity corresponding to the real-time training data and assigns an identity tag to the real-time training data. This technical solution is suitable for scenarios where a remote mobile communication terminal serves as the data processing module 300. The identity verification unit enables simultaneous classification, processing, and feedback of training data uploaded by multiple patients, thereby significantly improving device utilization efficiency. In practice, the identity verification unit can operate by displaying identity verification information through the data interaction module 400, or by pre-binding the communication addresses of each data acquisition module 200 with patient identity information and storing them in the data table of the data processing module 300. During operation, it reads the IP address of the currently uploaded training data in real time, obtains the corresponding patient information by comparing it with the data table, and then classifies and stores the training data in the corresponding patient's folder.

[0083] In practice, the training execution module 100 can adopt a manually driven hardware structure or a semi-automatic or automatic structure implemented by devices such as motors. Examples 2-3 below illustrate some implementation methods of the training execution module 100.

[0084] Example 2 is an implementation of the training execution module described in this invention. Please refer to it. Figure 3-6 :

[0085] In this example, the training execution module includes:

[0086] The replacement component includes at least one of a first execution component 110 for performing a mouth-opening action, a second execution component 120 for performing a mandibular protrusion action, and a third execution component 130 for performing a mandibular lateral action; the first execution component 110, the second execution component 120, and the third execution component 130 respectively include a maxillary positioning element for positioning the maxilla and a mandibular positioning element for positioning the mandible; the maxillary positioning element includes a maxillary alveolar bone 161, and the mandibular positioning element includes a mandibular alveolar bone 162.

[0087] The main body assembly 140 includes a first component and a second component, which are movably connected and the second component can move relative to the first component; the maxillary positioning component can be replaced and installed on the first component, and the mandibular positioning component can be replaced and installed on the second component.

[0088] Specifically, the main body assembly 140 includes an electric actuator 151 and a housing 152. The maxillary positioning component is replaceably mounted on the main body of the electric actuator 151, and the mandibular positioning component is replaceably mounted on the telescopic rod 153 of the electric actuator 151. In this example, the electric actuator 151 is mounted on the inner side of the housing 152, and the maxillary and mandibular positioning components extend outwards from the outer side of the housing 152.

[0089] The data acquisition module includes a pressure sensor 211 and a distance sensor. One end of the pressure sensor 211 is against the inner wall of the outer casing 152, and the other end is against the side of the main body of the electric push rod 151 facing away from the telescopic rod. The detection head 221 of the distance sensor is installed on the main body of the electric push rod 151, and the detection baffle 222 of the distance sensor is installed on the telescopic rod of the electric push rod 151. The detection head 221 is positioned directly opposite the detection baffle 222.

[0090] like Figure 3-4 The diagram shows a schematic of the structure when the first execution component 110 is installed on the main component 140 and mouth-opening action training is performed. In this installation structure, the maxillary positioning component and the mandibular positioning component in the first execution component 110 are arranged parallel to each other along a straight line on the surface of the outer shell 152, and extend in a direction perpendicular to the surface of the outer shell 152. The maxillary positioning component and the mandibular positioning component can move towards each other / away from each other along this straight line under the action of the electric push rod 151, thereby realizing the training of mouth-opening action.

[0091] like Figure 5The diagram shows a schematic of the structure when the second actuator 120 is mounted on the main component 140 and performs mandibular protrusion training. In this mounting structure, the maxillary and mandibular positioning components in the second actuator 120 are arranged parallel to each other along a straight line on the surface of the outer shell 152, and extend in the same direction parallel to the surface of the outer shell 152. The maxillary and mandibular positioning components can move towards or away from each other along this straight line under the action of the electric push rod 151, thereby achieving mandibular protrusion training.

[0092] like Figure 6 The diagram shows a schematic of the structure when the third actuator 130 is mounted on the main component 140 and performs mandibular lateral movement training. In this mounting structure, the maxillary and mandibular positioning components of the third actuator 130 are arranged parallel to each other along a straight line on the surface of the outer shell 152, and extend in a direction parallel to this straight line. The maxillary and mandibular positioning components can move towards or away from each other in a direction perpendicular to this straight line under the action of the electric push rod 151, thereby achieving mandibular lateral movement training.

[0093] In the above application example, the travel of the electric push rod 151 is adjustable, thereby adapting to the range of motion required for different stages of rehabilitation training.

[0094] Example 3 is another implementation of the training execution module described in this invention. Please refer to [the example]. Figure 7-9 :

[0095] In this example, the training execution module includes:

[0096] Main component 140, which includes an X-shaped cross arm, a slide bar 145, and a sliding sleeve 147; wherein,

[0097] The X-shaped cross arm includes a first arm and a second arm that are respectively L-shaped; the first arm includes a first arm segment 141, a first bending point and a second arm segment 142 connected in sequence; the second arm includes a third arm segment 143, a second bending point and a fourth arm segment 144 connected in sequence; the first arm and the second arm are fixed as one unit by the hinged connection between the first bending point and the second bending point.

[0098] One end of the slide rod 145 is hinged to the end of the first arm segment 141 via a connecting rod 146, and the other end of the slide rod 145 is connected to one of the maxillary positioning components. A sliding sleeve 147 is fitted onto the outside of the slide rod 145 and is fixed to the third arm segment 143 as a single unit via an intermediate member 148. In this example, the intermediate member 148 is V-shaped, connected to the sliding sleeve 147 via one connection point, and connected to the third arm segment 143 via two connection points. The other maxillary positioning component is fixedly connected to the end of the third arm segment 143.

[0099] In this example, the data acquisition module includes a distance sensor and a pressure sensor 211. The distance sensor is an infrared distance sensor 223, which is mounted on the guide sleeve with its detection head 221 facing the mandibular or maxillary positioning component. The pressure sensor 211 is a pressure membrane 212, which is disposed on the surface of the second arm segment 142 and the fourth arm segment 144. The pressure membrane 212 performs pressure conversion as follows: Assuming there are 1, 2, ... n force points on the pressure membrane 212, the force on the handle 142 is measured through the pressure membrane 212. The handle 142 is subjected to external forces F1, F2, ..., Fn, and the distances between these forces and the rotation midpoint of the X-shaped cross arm are d1, d2, ..., dn, respectively.
