[0009] An adaptive locking mechanism including an electromagnetic brake located at the connection between the sliding track and the spreading arm;

[0010] A control unit, electrically connected to the drive motor, the servo motor, the wireless transmission unit and the electromagnetic brake, receives feedback signals from the intelligent sensing module and controls the operation of the above components;

[0011] The power unit is integrated in the support frame and includes a rechargeable battery, a wireless charging module and an external power interface to supply power to the entire device.

[0012] Preferably, the flexible support pad is made of porous silica gel, and a micro vibration motor is embedded in the flexible support pad.

[0013] Preferably: the intelligent sensing module further includes an optical camera, a laser scanner, and an AI image processing unit, wherein: the optical camera and the laser scanner are integrated at the front end of the main support frame, and are used to collect multi-view images and three-dimensional point cloud data inside the oral cavity; the AI ​​image processing unit is configured to reconstruct the oral three-dimensional model through a point cloud stitching algorithm, and generate treatment path recommendations based on a preset lesion feature library; the operating wavelength range of the laser scanner is 850-1550nm.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. Double fixation and adaptive fit: The medical silicone layer is combined with the memory alloy frame to achieve comfort and adaptability of initial fixation; the reverse pressure of the open arm forms secondary fixation during treatment, which greatly reduces the risk of displacement and solves the problem of easy falling off and patient discomfort of traditional devices.

[0033] The structure and principle of the present invention will be fully described below in conjunction with specific embodiments, so that those of ordinary skill in the art can fully understand and implement it.

[0034] As Figures 1 to 5 shown, a support device for oral treatment disclosed by the present invention includes: a main support frame 1, which is in an arc structure matching the dental arch of the human mandible or maxilla. The inner surface thereof is closely attached to the physiological curve of the dental arch through a medical silicone layer 11, and the vertical height of the main support frame 1 does not exceed the occlusal surface of the teeth; a shape memory alloy skeleton 12 is arranged inside the main support frame 1; the shape adaptation is realized through the shape memory alloy skeleton 12, and its radian is automatically adjusted with the opening and closing angle of the patient's oral cavity. The shape memory alloy skeleton 12 adopts a frame structure similar to that in the construction field, which can save materials and improve the stability of the skeleton.

[0035] The adjustable spreading mechanism 2 is symmetrically arranged on both sides of the main support frame 1 and includes a sliding track 21, a driving motor 22, a spreading arm 23, and a flexible support pad 24. The sliding track 21 is located on the outer side wall of the main support frame 1. The driving motor 22 controls the spreading arm 23 to extend outward along the sliding track 21 in a gear-rack meshing manner. The extension angle deviates towards the middle of the oral cavity (i.e., extends obliquely upward towards the buccal mucosa), and an avoidance part 231 that bends towards the buccal mucosa is arranged at the end of the spreading arm 23. The radian of its bending towards the buccal mucosa is designed according to ergonomics, which can ensure avoiding the side of the posterior teeth in the oral cavity during spreading and prevent mechanical friction from damaging the enamel; an angle adjustment module 25 including a servo motor 251 and an arc gear and rack mechanism 252 is arranged between the spreading arm 23 and the avoidance part 231 for adjusting the angle of the avoidance part 231 to adapt to the spatial position difference between the buccal mucosa and the dental arch of different patients; the flexible support pad 24 is installed on the outer side surface of the avoidance part 231 and is made of porous silicone material. A micro vibration motor 241 is embedded inside it and starts when the oral temperature is abnormal to remind the patient and at the same time remind the doctor to pay attention to whether there is a surgical risk.

[0036] Through the above design, the device is stably placed in the oral cavity, avoiding the device offset that may be caused by the fixing method of traditional devices during treatment. Its fixing principle: The primary fixation is achieved through the friction between the medical silicone layer 11 and the surface of the dental arch. The microporous structure of the silicone layer increases the contact area and enhances the initial fixing force. The secondary fixation depends on the reverse pressure generated after the opening arms 23 of the adjustable opening mechanism 2 apply pressure to the buccal mucosa on both sides, forming a closed-loop fixing system of "dental arch - silicone layer - main support frame - opening arm - buccal mucosa". The dual fixing mechanism ensures that the device has no displacement during the treatment process.

[0037] Furthermore, it also includes an intelligent sensing module 3, integrated inside the main support frame 1, including a pressure sensor 31, a temperature sensor 32, an optical camera 33, a laser scanner 34 (with a wavelength range of 850 - 1550 nm to avoid harming oral tissues), an AI image processing unit, and a wireless transmission unit; among which: The pressure sensors 31 are distributed inside the medical silicone layer 11 and the flexible support pad 24 to monitor the dental arch contact pressure and the pressure on the buccal mucosa in real time; The temperature sensors 32 are arranged on the surface of the main support frame 1 in an array to monitor the oral cavity internal environment temperature and trigger an alarm when there is abnormal temperature rise (such as heat generated by the friction of treatment instruments or tissue inflammation); The optical camera 33 and the laser scanner 34 are integrated at the front end of the main support frame 1 to collect multi-view images and three-dimensional point cloud data of the oral cavity interior; The AI image processing unit is configured to reconstruct the three-dimensional model of the oral cavity through the point cloud stitching algorithm, generate personalized treatment path suggestions based on a preset lesion feature library (such as the morphological features of lesions such as dental caries and periapical periodontitis), and at the same time, combine the patient's historical data (such as previous treatment records and oral disease history), predict the possible risks during treatment (such as buccal mucosal pressure ulcers and instrument operation blind spots) through machine learning algorithms and give early warnings; The AI image processing unit associates the patient's historical data through machine learning algorithms, predicts the possible risks during the treatment process and gives early warnings; The wireless transmission unit supports dual-mode communication of Bluetooth and Wi-Fi, and transmits the monitoring data to the doctor's terminal or the cloud database in real time.

[0038] The adaptive locking mechanism includes an electromagnetic brake 4 located at the connection between the sliding track 21 and the opening arm 23. Through the electromagnetic brake 4, it is locked in time when the opening arm 23 reaches a suitable and stable state.

[0039] The control unit is electrically connected to the drive motor 22, the servo motor 251, the wireless transmission unit, and the electromagnetic brake 4, receives the feedback signals from the intelligent sensing module 3, and controls the operation of the above components;

[0040] The power unit, integrated within the support frame 1, includes a rechargeable battery, a wireless charging module, and an external power interface. It supports two charging methods and powers the entire device. The wireless charging module utilizes the principle of electromagnetic induction and can be charged by placing it on a dedicated charging base, avoiding interference from wired connections during treatment operations. The external power interface is used for rapid charging in case of emergencies to ensure the device's battery life.

[0041] This embodiment also discloses a usage method of the above-mentioned support device for oral treatment, including the following steps:

[0042] Step S1: Oral structure scanning and three-dimensional modeling;

[0043] Gently place the main support frame 1 into the patient's oral cavity, and the medical silicone layer 11 naturally adheres to the dental arch. The control unit activates the optical camera 33 and the laser scanner 34 to collect image and point cloud data of areas within the oral cavity, including the buccal mucosa, teeth, gums, etc. The AI image processing unit 35 splices the multi-viewpoint clouds through a feature matching algorithm to generate a three-dimensional model, which is synchronously displayed on the doctor's terminal.

[0044] Step S2: Adaptive expansion adjustment and lesion exposure;

[0045] Automatically adjust the extension length of the adjustable expansion mechanism 2 and the angle of the avoidance part 231 according to the three-dimensional model until the flexible support pad 24 is in uniform contact with the patient's buccal mucosa, and lock it through the adaptive locking mechanism.

[0046] If the AI image processing unit 35 identifies a lesion area (for example, a dental carie is located on the buccal side of a molar), the control unit sends an instruction to the drive motor 22, and through the gear-rack transmission, the expansion arm 23 extends further outward to a preset length. At the same time, the servo motor 251 drives the arc gear-rack mechanism 252 to further adjust the angle of the avoidance part 231 to an appropriate angle, so that the flexible support pad 24 adheres to the buccal mucosa and pushes aside the soft tissue, ensuring that the lesion is completely exposed to the doctor's field of vision. The pressure sensor 31 continuously monitors the contact pressure between the silicone layer and the dental arch, and through feedback control, makes the expansion force evenly distributed (avoiding the mucosal damage threshold).

[0047] Step S3: Dynamic monitoring and intelligent adjustment;

[0048] During the treatment process, the temperature sensor 32 continuously collects the oral temperature. When it detects that the local temperature exceeds the preset abnormal threshold (for example: 37.5°C), the control unit activates the micro vibration motor 241 and simultaneously sends an alarm to the doctor's terminal through the wireless transmission unit (Bluetooth / Wi-Fi dual-mode). If the pressure sensor 31 detects that the single-point pressure exceeds the preset threshold, the control unit automatically fine-tunes the angle of the expansion arm 23 to equalize the pressure. The AI image processing unit synchronously analyzes the camera image, identifies the distance between the instrument operation position and the lesion edge, and generates a prompt for the safe operation area.

[0049] Step S4: Automatic resetting and removal.

[0050] After the treatment, the control unit sends a signal to the electromagnetic brake 4 to unlock, and the drive motor 22 rotates in the opposite direction to retract the opening arm 23 to the initial position. The doctor manually removes the main support frame 1, and the device enters the standby state. The wireless charging module automatically detects the power level and prompts charging when it is lower than the preset value (for example: 20%).

[0051] In order to further verify the technical effect of the present invention, 50 oral treatment patients (aged 18-65 years old, including 25 root canal treatments, 15 caries restorations, and 10 periodontal surgeries) were selected as test subjects, and a comparative experiment was conducted with the traditional mechanical distraction device. The test data are as follows:

[0052] Fixed stability comparison:

[0053] Table 1

[0054] Index The present invention (n = 50) Traditional device (n = 50) Number of cases with displacement during treatment 0 18 Single adjustment frequency (times / treatment) 0.2±0.1 1.8±0.5 .

[0055] It can be seen from Table 1 that the present invention achieves zero displacement through dual fixation of "friction force of medical silicone layer + reverse pressure of the spreading arm" combined with the adaptive deformation of the memory alloy skeleton; the traditional device relies on a single silicone friction force, and the displacement rate is as high as 36% due to patient swallowing, oral secretions, etc., and frequent manual adjustment is required.

[0056] Comparison of mucosal protection effects:

[0057] Table 2

[0058] Index The present invention (n = 50) Traditional device (n = 50) Rate of buccal mucosa swelling 3 cases (6%) 14 cases (28%) Incidence of pressure ulcers 0 5 cases (10%) Contact pressure uniformity - standard deviation ≤5 kPa ≥15 kPa .

[0059] It can be seen from Table 2 that the porous silicone material and angle of the flexible support pad of the present invention are adaptively adjusted to make the contact pressure evenly distributed; the traditional device has a fixed opening angle, which easily leads to local pressure concentration, exceeding the tolerance threshold of the mucosa and causing the disease.

[0060] Comparison of intelligent monitoring and treatment efficiency:

[0061] Table 3

[0062] Index The present invention (n = 50) Traditional device (n = 50) Treatment time (minutes) 42.5±5.2 58.3±8.5 Lesion exposure time (seconds) Auto-complete (<10s) Manual adjustment (60 - 120 s) Accuracy rate of risk warning 92% (23 / 25 cases) None .

[0063] It can be seen from Table 3 that the AI ​​image processing unit is based on the three-dimensional modeling of the laser scanner, and can quickly (10 seconds) automatically adjust the angle and length of the expansion arm to expose the lesion area; traditional devices require doctors to make multiple visual adjustments, which significantly increases the time consumption.

[0064] The above embodiments are only the preferred embodiments of the present invention and do not impose any formal restrictions on the present invention. Any person skilled in the art can, without departing from the technical principles and scope of the present invention, make many possible changes and modifications to the technical solution of the present invention by using the methods disclosed above, or modify it into equivalent embodiments with equivalent changes. Therefore, any combination, modification or replacement of the technical features disclosed in the present invention made in accordance with the technical essence of the present invention without departing from the principles or scope of the present invention shall fall within the protection scope of the technical solution of the present invention.
