Description

Technical Field

[0001] This invention belongs to the technical field of oral medicine teaching and training equipment, and specifically relates to an intelligent teaching and training system for oral medicine teaching. Background Technology

[0002] Oral medicine is a discipline highly dependent on the dentist's practical skills. Percussion and periodontal probing are fundamental oral examination procedures and core skills that dentists must master, requiring precise control of the force and angle of the examination. However, in teaching, these procedures primarily rely on an "apprenticeship" system of experience transmission—instructors pass on experiential knowledge such as the force of manipulation and tactile judgment through verbal explanation, demonstration, and real-time correction. Due to the lack of quantifiable indicators, students struggle to understand and master this tactile sensation, which is a challenge in clinical oral teaching. Current skills training methods have the following limitations: (1) The experience of touch is difficult to quantify objectively. Key parameters such as percussion force and probing pressure are essentially muscle memory accumulated through repeated practice. Their appropriate range is often described in vague terms such as "gentle" and "moderate", lacking objective standards that can be quantified and reproduced. Students can only rely on the teacher's subjective perception and judgment and their own extensive repetitive practice to gradually understand, resulting in a long training cycle and inconsistent results.

[0003] (2) Teaching feedback is seriously delayed. In the traditional teaching model, if students apply too little or too much force or the angle is wrong, the teacher often has to review and correct them one by one after the practice. In the process, there is a lack of real-time and accurate feedback mechanism, making it difficult for students to establish the correct force perception at the moment of operation, which easily leads to the solidification of incorrect hand feel.

[0004] (3) Uneven distribution of teaching resources. When a teacher guides multiple students at the same time, it is difficult to monitor the operation quality of each student in real time, resulting in errors in strength and technique not being detected and corrected in time. The teaching quality is highly dependent on the teacher's personal energy.

[0005] (4) Training data cannot be recorded and traced back. Traditional practice processes do not generate any objective data, students cannot review their own operation history for targeted improvement, and teachers also find it difficult to evaluate students' ability growth curves based on objective data, resulting in a lack of data support for teaching process management. Summary of the Invention

[0006] To solve the above problems, the present invention adopts the following technical solution: An intelligent teaching and training system for oral medicine education includes: A smart teaching handle, wherein a display screen is provided on the smart teaching handle; A replaceable working head is provided, which is detachably connected to the intelligent teaching handle via a quick-change interface. A pressure sensor is disposed at one end of the intelligent teaching handle near the replaceable working head; An attitude / contact sensing unit is disposed inside the intelligent teaching handle and on the end face of the replaceable working head, for sensing the spatial attitude of the intelligent teaching handle and the contact state between the replaceable working head and the tooth surface. A microprocessor is mounted on the intelligent teaching handle and is connected to the display screen, the pressure sensor, and the posture / contact sensing unit circuit, respectively. The microprocessor is used to receive the sensing data from the pressure sensor and the posture / contact sensing unit, compare the measured force with the preset teaching appropriate range, and transmit the comparison result and posture / contact judgment result to the display screen. The teacher monitoring APP is installed on the teacher's terminal device and communicates with the smart teaching handle through a wireless communication module. The wireless communication module is used to transmit the operation data collected by the smart teaching handle to the teacher monitoring APP in real time and to receive configuration parameter updates issued by the teacher monitoring APP.

[0007] Furthermore, the replaceable working head includes a dental percussion head and / or a periodontal probe head.

[0008] Furthermore, the pressure sensor is arranged along the longitudinal axis of the intelligent teaching handle on the force transmission path. The force on the replaceable working head is transmitted through the pressure sensor. The pressure sensor is used to collect the magnitude of the force applied by the student to the replaceable working head in real time and convert the mechanical signal into an electrical signal and transmit it to the microprocessor.

[0009] Furthermore, the teacher monitoring APP is used to connect to and monitor multiple smart teaching handles simultaneously, display the operation data of each student in real time, and uniformly set training parameters.

[0010] Furthermore, the intelligent teaching handle is also equipped with an audio-visual alarm module, which is connected to the microprocessor. The audio-visual alarm module can control the triggering of an alarm based on the comparison results and posture / contact judgment results.

[0011] Furthermore, the attitude / contact sensing unit includes: IMU is used to detect the attitude angle of the smart teaching handle in three-dimensional space; Four miniature tactile switches are disposed on the end face of the replaceable working head to detect the contact state between the replaceable working head and the tooth surface.

[0012] Furthermore, the teacher monitoring app includes: A real-time monitoring module, which is connected to the microprocessor, is used to display the operation force curve, contact status, number of errors and alarm types of each student in the form of a list or chart. A parameter setting module, which is connected to the microprocessor, is used for teachers to set the training parameters of each smart teaching handle either uniformly or individually. A data playback module, which is connected to the real-time monitoring module, is used to play back the student's historical operation process; The report generation module, which is connected to the real-time monitoring module, is used to generate a training report that includes the number of operations, intensity distribution statistics, error type distribution, and ability growth curve.

[0013] Furthermore, the display screen is located on the side of the handle and is used to display the force value, color block status, and operation prompt text in real time; the color block status includes green for normal, yellow for light, and red for heavy; the operation prompt text includes moderate, too heavy, too light, and angle deviation.

[0014] Beneficial effects: 1. Achieving objective quantification of operational feel. This invention embeds a high-sensitivity pressure sensor into the force path of the handle, transforming vague descriptions such as "gentle" and "moderate" in traditional teaching into quantifiable force values ​​(100-200g), and establishing a standard for appropriate teaching ranges. This provides an objective and reproducible basis for judging the training of percussion and probing force, overcoming the technical difficulty of quantifying and transmitting tactile experience in traditional teaching models.

[0015] 2. Provides real-time and accurate operational feedback. This invention compares sensor data with preset standards in real time through a microprocessor, and with the help of numerical / color block displays on the screen and instant prompts from the sound and light alarm module, students can perceive whether the force is appropriate and the posture is correct at the moment of operation. This enables them to establish correct force perception and muscle memory in real time during practice, effectively avoiding the solidification of incorrect hand feel and overcoming the technical defects of seriously delayed feedback in traditional teaching.

[0016] 3. Enables multi-terminal collaborative management and large-scale teaching. This invention can simultaneously connect to and monitor multiple smart teaching handles, display the operation data of each student in real time, and uniformly set training parameters. Teachers can monitor the operation status, intensity curves, and error types of all students in the class in real time through the teacher monitoring APP, quickly locate students who need guidance, significantly improve the efficiency of teacher utilization and teaching management capabilities, and overcome the technical bottleneck of traditional teaching where one teacher cannot monitor multiple students at the same time.

[0017] 4. Enables recording and backtracking of training data. This invention can completely record training data such as the operational force curve, contact state, and number of errors for each student, supporting historical playback and ability growth curve assessment. It provides objective data support for teaching process management and overcomes the technical shortcomings of traditional training that does not generate any objective data and cannot be backtracked for analysis.

[0018] 5. Achieving dual functionality with a single handle and streamlined equipment. This invention enables quick and easy replacement of the percussion head and probe head via a quick-change interface. One handle can be used to train both percussion and probing skills, eliminating the need to purchase separate dedicated equipment, reducing teaching costs, and improving equipment utilization.

[0028] The periodontal probe tip 10 is made of medical-grade stainless steel and can be sterilized under high temperature and pressure. The tip diameter is 0.5-0.7mm, which is a standard probe specification. The front end is equipped with 4 tactile sensing points to detect the contact position during probing. As the end effector of the probing operation, it receives the probing force applied by the student and transmits it to the pressure sensor. At the same time, it senses the contact position through the tactile sensing points at the front end.

[0029] Preferably, the pressure sensor 3 is arranged along the longitudinal axis of the intelligent teaching handle 1 on the force transmission path. The force on the replaceable working head is transmitted through the pressure sensor 3. The pressure sensor 3 is used to collect the magnitude of the force applied by the student to the replaceable working head in real time and convert the mechanical signal into an electrical signal and transmit it to the microprocessor 4.

[0030] In this embodiment, the force applied to the replaceable working head is transmitted via pressure sensor 3; the range covers the typical force range of oral percussion and probing (100-200g); it is highly responsive, collects data in real time, and has no significant delay. The force applied by the student to the working head is collected in real time, and the mechanical signal is converted into an electrical signal and transmitted to the microprocessor 4 for processing and judgment.

[0031] Preferably, the teacher monitoring APP 8 is used to connect to and monitor multiple smart teaching handles 1 simultaneously, display the operation data of each student in real time, and set training parameters uniformly.

[0032] Preferably, the intelligent teaching handle 1 is also equipped with an audible and visual alarm module 6, which is connected to the microprocessor 4. The audible and visual alarm module 6 can control the audible and visual alarm module 6 to trigger an alarm based on the comparison results and posture / contact judgment results.

[0033] In this embodiment, the audible and visual alarm module includes a piezoelectric ceramic buzzer (sound alarm) and a flat vibration motor (tactile alarm); the alarm response time is <50ms; it supports multiple alarm rhythms to distinguish different error types (too light, too heavy, incorrect posture). When a student's operating force exceeds the preset range or an incorrect posture / contact occurs, it immediately emits sound and / or vibration prompts to help the student perceive and correct the error on the spot.

[0034] Preferably, the attitude / contact sensing unit 5 includes: IMU (accelerometer + gyroscope) is used to detect the attitude angle of the smart teaching handle in three-dimensional space; Four miniature tactile switches are located on the end face of the replaceable working head to detect the contact status between the replaceable working head and the tooth surface.

The parameter setting module is connected to the microprocessor and is used by teachers to set the training parameters of each smart teaching handle either uniformly or individually. The data playback module is connected to the real-time monitoring module and is used to play back the student's historical operation process. The report generation module, connected to the real-time monitoring module, is used to generate training reports that include the number of operations, intensity distribution statistics, error type distribution, and ability growth curves.

[0037] Working principle: During training, students install the dental percussion head 9 onto the quick-change interface 2 and perform percussion operations on the dental model. The pressure sensor 3 collects the percussion force in real time (sampling rate 200Hz), and the microprocessor 4 compares the measured force with a preset appropriate range. When the force is within the appropriate range, the display screen 7 shows a green block and a "moderate" prompt; when the force is too light, a yellow block and a "too light" prompt are displayed, and a short alarm is triggered; when the force is too heavy, a red block and a "too heavy" prompt are displayed, and a long alarm and vibration are triggered. At the same time, the posture / contact sensing unit 5 detects whether the percussion angle is perpendicular. If the angle is skewed, the display screen 7 displays an "angle deviation" prompt and triggers a specific rhythm alarm. All operation data is uploaded to the teacher monitoring APP 8 in real time via the wireless communication module 8.

[0038] When used for periodontal probing skills training, the dental percussion head 9 is replaced with a periodontal probe head 10. Students install the periodontal probe head 10 onto the quick-change interface 2 and perform periodontal probing operations on a dental model. The preset appropriate force range in the microprocessor 4 is adjusted. The pressure sensor 3 collects the probing force in real time, and the display screen 7 displays the force value and status color block in real time. Four tactile sensing points at the front end detect the contact position between the probe tip and the tooth surface. When probe slippage or incorrect contact position is detected, the posture / contact sensing unit 5 sends a signal to the microprocessor 4, triggering the audible and visual alarm module 6 to issue an alarm, and the display screen 7 displays the "Incorrect Contact Position" prompt. The teacher monitoring APP 8 can view the probing force curve and contact status of each student in real time.

[0039] Teachers uniformly set training parameters through the Teacher Monitoring APP8. The Teacher Monitoring APP8 simultaneously connects to 30 smart teaching handles 1. Teachers uniformly set appropriate ranges for percussion and probing pressure on the Teacher Monitoring APP8, and the configuration parameters are synchronously transmitted to the microprocessor 4 of each handle via a wireless communication module. During training, the Teacher Monitoring APP8 displays each student's operation pressure curve, contact status, number of errors, and alarm type in real time in list or chart format. Teachers can click on any student's entry to view detailed operation data and replay the operation process. After training, the Teacher Monitoring APP8 automatically generates a training report for each student, including the number of operations, pressure distribution statistics, error type distribution, and ability growth curve.
