Technical Field
[0001] This invention relates to the field of dental education, and in particular to a touch control system for oral cavity simulation teaching. Background Technology
[0002] Dental students need to conduct simulated dental treatment learning. Currently, dental students directly operate dental treatment equipment on head models during their dental treatment learning. During the operation, students cannot understand the use of the equipment and the speed, efficiency, and precision of grinding teeth in real time. Because dental teachers have difficulty understanding the specific operation of each student in the simulation, it is difficult to identify problems in the students' simulation operation in time, and therefore it is difficult to correct students in real time. Furthermore, it is difficult to objectively evaluate students during dental treatment examinations. Summary of the Invention
[0003] To overcome the above-mentioned shortcomings, the present invention provides a dental simulation teaching touch control system, which facilitates students and teachers to understand the accuracy and standardization of dental clinical practice operations in real time, thus facilitating dental clinical teaching.

The data recording module is electrically connected to the touch screen, and the touch screen can display the data recorded by the data recording module.
[0010] As a further improvement of the present invention, the simulation operation device further includes a fixed base, a lifting column, and a lifting drive device. The fixed end of the lifting column is installed on the fixed base, and the moving end of the lifting column can extend and retract in the vertical direction. The lifting drive device drives the movement of the lifting column to extend and retract. The main body of the device is fixedly installed on the moving end of the lifting column. The simulation operation device also includes a head mold fixing seat and a pitch angle adjustment drive device. The head mold fixing seat is fixed to one side of the main body of the device. The simulated head mold is installed on the head mold fixing seat and can rotate forward and backward around a horizontal axis. The pitch angle adjustment drive device drives the simulated head mold to rotate forward and backward to change the head tilt angle of the simulated head mold. The touch screen is provided with an up button, a down button, a tilt button, and a pitch button. The up button and the down button are electrically connected and communicate with the lifting drive device, and the tilt button and the pitch button are electrically connected and communicate with the pitch angle adjustment drive device.

The foot control button is electrically connected to the control system, and the control system controls the start and stop of the pneumatic drive device. At least one support arm is hinged to the main body of the system. Two or more support arms are sequentially hinged together. The bracket is fixedly installed on the support arm at the end of the sequential hinge. The first support arm and the main body are respectively hinged to the two ends of a controllable gas spring to form a triangular structure. The two adjacent support arms are also respectively hinged to the two ends of a controllable gas spring to form a triangular structure. The main body of the system is also equipped with at least one support arm positioning key. The support arm positioning key is electrically connected to the control circuit of the controllable gas spring in a one-to-one correspondence.
[0013] As a further improvement of the present invention, the foot pedal is also provided with an adjustment switch for controlling the lifting drive device and the pitch angle adjustment drive device. The foot pedal is a multimedia wireless foot pedal, which communicates wirelessly with the control system via a wireless network or Bluetooth. The simulation operation device also includes a teaching pendant and a shadowless lamp. The foot pedal is also provided with a teaching pendant control switch for controlling the zoom and focus of the teaching pendant and a shadowless lamp control switch for controlling the brightness of the shadowless lamp. The teaching pendant control switch and the shadowless lamp control switch communicate with the teaching pendant and the shadowless lamp via a wireless network or Bluetooth, respectively.
[0014] The beneficial effects of this invention are as follows: By installing a touchscreen on the main body of the system, the system communicates with the control system. The touchscreen displays the working status of each dental handpiece, saliva suction device, and scaler, as well as the rotation speed of the dental handpiece. The control system sets the required rotation speed for high- and low-speed dental handpieces. The touchscreen displays whether the current dental handpiece rotation speed is too low, appropriate, or too high, allowing the operator to monitor the handpiece rotation speed in real time and adjust it for precise tooth grinding. This invention also allows the touchscreens of each simulation device to be displayed simultaneously with the teacher's smart electronic device, enabling the teacher to monitor each student's simulation operation in real time and provide real-time guidance to students with operational problems. Furthermore, this invention includes an examination system that allows students to take self-administered dental simulation operation exams. After the exam, a scoring module accurately scores the students' operations and provides accurate evaluation of their simulations. This invention achieves intelligent teaching and examination of the simulated dental treatment process, which is beneficial for students to cultivate good operating habits and improve their dental treatment skills during their school internships.

[0021] Example: A touch control system for oral simulation teaching includes at least one simulation operation device. The simulation operation device includes a system body 1, a hanger 3, hanger valves 4, a dental handpiece 6, a saliva suction device 8, a dental scaler 16, a foot pedal 13, a drive air control switch 2, a negative pressure control switch 9, a drive air supply device 15, an air pipe 14, a negative pressure supply device 17, a dental scaler control switch 10, a water supply device 11, a water pipe 12, and a control system 18. At least one hanger 3 is mounted on the system body 1. The hanger 3 is equipped with several hanger valves 4. The saliva suction device 8, the dental scaler 16, and at least one dental handpiece 6 can be hung on the hanger valves 4 of the hanger 3. The drive air control switch 2, the negative pressure control switch 9, the drive air supply device 15, the air pipe 14, the negative pressure supply device 17, the dental scaler control switch 10, the water supply device 11, the water pipe 12, and the control system 18. At least one hanger 3 is mounted on the system body 1. The hanger 3 is equipped with several hanger valves 4. The saliva suction device 8, the dental scaler 16, and at least one dental handpiece 6 can be hung on the hanger valves 4 of the hanger 3. Control switch 9 and cleaning control switch 10 are respectively installed on foot pedal 13. Drive air supply device 15 provides drive air to dental handpiece 6 and cleaning machine 16 through air pipe 14. Drive air control switch 2 controls the opening and closing of air pipe 14, which provides drive air to dental handpiece 6 and cleaning machine 16, as well as the airflow magnitude within air pipe 14. Negative pressure control switch 9 controls negative pressure supply device 17 to provide negative pressure suction to saliva aspirator 8 through air pipe 14. Cleaning control switch 10 controls water supply device 11 to provide cleaning water to cleaning machine 16 through water pipe 12. Drive air control switch 2 is electrically connected to control system 18 via pneumatic-electric conversion circuit. The bracket 3 is used to hang dental handpiece 6 and saliva aspirator 8. Valve 4 is electrically connected to and communicates with control system 18. Control system 18 controls the start and stop of each dental handpiece 6 and controls the negative pressure supply device 17 to provide negative pressure to saliva suction device 8. The simulation operation device also includes touch screen 5, simulated head mold 7, air pressure detection device 20, water pressure detection device 21, and negative pressure detection device 19. The simulated head mold 7 is fixedly installed on one side of the system body 1. The simulated head mold 7 has simulated teeth inside its oral cavity. Touch screen 5 is fixedly installed on hanger 3. The hanger valve 4 of hanger 3 has a sensor that can sense the dental handpiece 6, saliva suction device 8, and dental scaler 16 located in hanger valve 4. The sensor is electrically connected to and communicates with control system 18. The air pressure detection device can sense the dental handpiece 6, saliva suction device 8, and dental scaler 16 located in hanger valve 4. The air pressure detection device 21 can detect the inlet water pressure of the dental cleaning machine 16, and the negative pressure detection device 19 can detect the negative pressure in the suction tube. The air pressure detection device, water pressure detection device 21 and negative pressure detection device 19 are electrically connected to the control system 18 for signal transmission. At the same time, the control system 18 can convert the air pressure value into the rotation speed value of the dental handpiece 6 after calculation. The control system 18 controls the touch screen 5 to display the air pressure value detected by the air pressure detection device, the water pressure value detected by the water pressure detection device 21, the negative pressure value detected by the negative pressure detection device 19, the working status of each dental handpiece 6, saliva aspirator 8 and dental cleaning machine 16 and the rotation speed of each dental handpiece 6.
[0022] During dental treatment simulation clinical practice, dental students use a handheld dental handpiece 6, saliva aspirator 8, or dental scaler 16 to perform hands-on practice on simulated teeth within a simulated head model 7. During the practice, when the dental handpiece 6 is removed from the hanger valve 4, the corresponding sensor is activated, and simultaneously, the air supply tube 14 for the dental handpiece 6 opens through a diaphragm valve. The operator then presses the drive air control switch 2 on the foot pedal 13 to ensure the removed dental handpiece 6 receives normal air supply. The rotation speed of the dental handpiece 6 is controlled by the degree of pressure applied to the drive air control switch 2 on the foot pedal 13. When suction is needed, the saliva aspirator 8 is removed from the hanger valve 4, and the corresponding sensor... When the device is activated, the air pipe 14 connecting the saliva suction device 8 and the negative pressure supply device 17 (vacuum generator) opens through the diaphragm valve, causing the removed saliva suction device 8 to generate negative pressure and suck away saliva in the mouth. When teeth cleaning is needed, the scaler 16 is removed from the hanger valve 4, and the corresponding sensor is activated. At the same time, the water pipe 12 connecting the scaler 16 and the water supply device 11 opens through the diaphragm valve, allowing the removed scaler 16 to spray water into the mouth. Whether each sensor is activated can be viewed on the touch screen 5 by checking the status of the dental handpiece 6, saliva suction device 8, and scaler 16, making it easy to know which treatment device has been activated. Simultaneously, the pressure of the driving air is monitored in real time by the air pressure detection device, and the linear change graph (calculated and simulated in the background) is used to convert it into a rotation speed value, which is displayed on the speedometer of the touch screen 5. This allows for real-time monitoring of the grinding speed and efficiency of the dental handpiece 6 during the student's simulated practical operation. During saliva suction, the vacuum degree of the saliva suction device 8 is detected by the negative pressure detection device 19 connected to the suction tube of the saliva suction device 8, and the vacuum degree is displayed on the touch screen 5, allowing for real-time monitoring of the saliva suction situation. When the dental cleaning machine 16 is performing a dental cleaning operation, the status of the dental cleaning machine 16 can also be viewed on the touch screen 5.
[0023] The aforementioned internship system allows students to view the real-time status of the equipment on the touchscreen 5 during their simulated dental clinical practice. This facilitates students' understanding of the equipment and enables them to operate it effectively. It also allows instructors to monitor each student's progress and provide timely guidance and correction. This comprehensive system allows students to fully practice and learn during their simulated dental clinical internship, effectively improving their simulation skills and accumulating experience. This benefits students by enabling them to quickly and accurately perform clinical procedures after graduation, effectively preventing dental treatment errors.
[0024] The touchscreen 5 has a dental handpiece 6 speed display, which is set with a low-speed display area, a reasonable speed display area, and an overspeed display area. The control system 18 also has a dental handpiece 6 speed storage module, which can store preset speed data of the dental handpiece 6. The control system 18 can compare the real-time speed value of the dental handpiece 6 with the preset speed data of the dental handpiece 6 in the dental handpiece 6 speed storage module, and the control system 18 will display the compared dental handpiece 6 speed value in the corresponding low-speed display area, reasonable speed display area, and overspeed display area on the touchscreen 5.
[0025] The rotational speed of the dental handpiece 6 during tooth grinding is displayed on the touchscreen 5 using a speedometer. When the student removes the handpiece 6 and uses pneumatic drive to rotate it for grinding, the strength of the pneumatic drive is controlled by the pressure applied to the foot, thus controlling the handpiece 6's rotational speed. The displayed value on the touchscreen 5 speedometer varies depending on the required rotational speed for high-speed and low-speed handpieces. Low-speed, reasonable-speed, and overspeed display zones are provided to allow users to monitor the grinding speed and efficiency in real time, enabling more precise grinding.
[0026] The dental handpiece 6 is equipped with an LED light, and the touchscreen 5 also has an LED light on / off button. The pneumatic control switch 2 on the foot pedal is connected in parallel with the LED light on / off button on the touchscreen 5, and then connected in series with the LED light through a delay circuit. The LED light is controlled to turn on and off via the LED light on / off button on the touchscreen 5 or the pneumatic control switch 2 on the foot pedal 13. When the foot pedal 13 switch is released, the LED light on the dental handpiece 6 turns off. Due to the delay circuit on the control system 18, the LED light turns off after a delay. The LED light can be turned on or off by repeatedly pressing the button on the touchscreen 5; or the LED light on the dental handpiece 6 can be turned on by pressing the pneumatic control switch 2 on the foot pedal 13 to control the pneumatic device of the foot pedal 13. When the pneumatic control switch 2 on the foot pedal 13 is released, the delay circuit causes the LED light to turn off after a delay. Furthermore, the illumination and delayed extinguishing of the LED light of the dental handpiece 6 are controlled by the drive air control switch 2, which helps to enable contactless activation of the dental handpiece 6 illumination and achieve aseptic operation. At the same time, the delayed extinguishing of the LED allows the user to observe the grinding of the lower tooth when the handpiece rotation stops.
[0027] Each dental handpiece 6 is connected by a linkage circuit, which allows only one dental handpiece 6 to be activated at a time.
[0028] When using a dental handpiece 6, it can only function properly when only one handpiece 6 is removed from the holder 3. If two or more handpieces 6 are removed from the holder valve 4, none of them can be used. This prevents situations where one handpiece is removed from the holder valve 4 and not promptly returned, leading to the removal of another handpiece for use. It also avoids injuries caused by improperly returned handpieces and cultivates a good habit among students of immediately returning handpieces after use, preventing medical accidents during actual dental treatments due to handpieces not being promptly returned to their proper places.
[0029] The simulation operation device also includes a screen mirroring signal transceiver, which is electrically connected and communicates with the control system 18. The screen mirroring signal transceiver module can wirelessly communicate with the intelligent electronic device, and the intelligent electronic device can display on the same screen as the touch screen 5 through the screen mirroring signal transceiver.
[0030] By using 4G networks or Bluetooth, the functions on the smartphone are kept consistent with those on the touchscreen 5, allowing the smartphone to display all device statuses and control device usage.
[0031] The simulation operation device also includes an examination system, which comprises an examination button, an equipment start module, a timing module, and a data recording module. The examination button is located on the touch screen 5. The examination button is electrically connected to the equipment start module, the timing module, and the data recording module via circuitry. The equipment start module can control the on / off of the air supply path of the dental handpiece 6. The timing module can time the start-up time of the dental handpiece 6. The timing module is electrically connected to the equipment start module. The data recording module can record the usage time of the dental handpiece 6 during the examination, the rotation speed of the dental handpiece 6 at different time periods, and the maximum rotation speed of the dental handpiece 6. The data recording module is electrically connected to the touch screen 5, and the touch screen 5 can display the data recorded by the data recording module.
[0032] By flipping through the pages, you can access the examination mode interface on touchscreen 5. Clicking the examination button puts the device into examination mode. In this mode, the air supply to the dental handpiece 6 is disconnected by the device's startup module, rendering the high-speed and low-speed dental handpieces unusable. The timing module only starts counting down after the examination has been set and confirmed, at which point the high-speed and low-speed dental handpieces can be used. When the countdown ends, the air supply to the high-speed and low-speed dental handpieces is cut off again, stopping them. Upon exiting examination mode, the high-speed and low-speed handpieces resume normal operation. Basic examination information is displayed on touchscreen 5, allowing for timely and accurate assessment of the student's simulated clinical procedures. This information includes the usage time of the dental handpieces during the examination, the usage time of the dental handpieces at each speed range, and the maximum speed of the dental handpieces during the examination. This facilitates a preliminary assessment of the accuracy of the hardware used by the student during their practical training.
[0033] The simulation operation device also includes a fixed base 25, a lifting column 26, and a lifting drive device. The fixed end of the lifting column 26 is installed on the fixed base 25, and the moving end of the lifting column 26 can extend and retract in the vertical direction. The lifting drive device drives the movement of the lifting column 26 to extend and retract. The main body of the device is fixedly installed on the moving end of the lifting column 26. The simulation operation device also includes a head mold fixing seat 23 and a pitch angle adjustment drive device 24. The head mold fixing seat 23 is fixed to one side of the main body of the device. The simulated head mold 7 is installed on the head mold fixing seat 23 and can rotate around a horizontal axis in both directions. The pitch angle adjustment drive device 24 drives the simulated head mold 7 to rotate in both directions to change the head tilt angle of the simulated head mold 7. The touch screen 5 is provided with an up button, a down button, a tilt button, and a pitch button. The up button and the down button are electrically connected to the lifting drive device for communication, and the tilt button and the pitch button are electrically connected to the pitch angle adjustment drive device 24 for communication.
[0034] The touch screen 5 has four buttons for raising, lowering, and tilting, which drive the raising drive and the tilt angle adjustment drive 24, thereby adjusting the height of the hanger 3 and the tilt angle of the head model 7. This is suitable for operators of different heights and for grinding teeth in different parts of the body. The raising drive and the tilt angle adjustment drive 24 are motor drive mechanisms.
[0035] The simulation operation device also includes several Hall elements, each of which can record at least one operating position of the lifting drive device and the pitch angle adjustment drive device 24. The touch screen 5 is also equipped with memory buttons that are electrically connected and communicate with each Hall element. Each memory button can trigger each Hall element to transmit the recorded height data of the bracket 3 and the pitch angle data of the simulated head model 7 to the control system 18. The control system 18 can drive the lifting drive device and the pitch angle adjustment drive device 24 to the operating position recorded by the corresponding Hall element. The device also includes a device reset module and a master control key. The master control key is electrically connected and communicates with the device reset module. The device reset module stores the initial data of the simulation operation device and can be electrically connected and communicates with the control system 18 of each simulation operation device.
[0036] The Hall effect sensor records the positions of the lifting drive and the pitch angle adjustment drive 24, thereby recording the height and pitch angle of the head mold 7. When the head mold 7 is readjusted and wants to return to the previously recorded position, simply press and hold the memory button for the previously recorded position, and the head mold 7 will reach the previously recorded position. Generally, the Hall effect sensor can record multiple positions of the head mold 7, and then the head mold 7 can be reset to different memory positions through different memory buttons. For example, more than five memory positions can be set to achieve rapid reset of multiple positions, improving the position adjustment speed of the head mold 7.
[0037] After the clinical internship ends, teachers can communicate with the control system 18 of each simulation operation device through the master control key to restore all simulation operation devices to their initial settings with one click. This facilitates the next simulation internship operation and avoids situations where simulation operation devices in the classroom are not reset, which could affect the next simulation internship operation. This ensures that each simulation internship operation can start smoothly.
[0038] The fixed base 25 has four directional wheels 27 and two rubber feet that can move up and down at its lower end. The fixed base 25 is also equipped with a pneumatic drive device that can drive the rubber feet to move up and down. The touch screen 5 is also equipped with a foot control button for controlling the pneumatic drive device to start and stop. The foot control button is electrically connected to the control system 18 for communication. The control system 18 controls the pneumatic drive device to start and stop. At least one support arm 28 is hinged on the system body 1. Two or more support arms 28 are sequentially hinged together. The bracket 3 is fixedly installed on the support arm 28 at the end of the sequential hinge. The first support arm 28 and the system body 1 are respectively hinged to the two ends of a controllable gas spring to form a triangular structure. The two adjacent support arms 28 are also respectively hinged to the two ends of a controllable gas spring to form a triangular structure. The system body 1 is also equipped with at least one support arm positioning key 29. The support arm positioning key 29 is electrically connected to the control circuit of the controllable gas spring in a one-to-one correspondence.
[0039] By activating the device positioning key, the foot drive mechanism (ideally a cylinder, but a motor can also be used) installed at the bottom of the frame is activated, securing the device to the ground using rubber feet, thus fixing the device in the designated position. When relocation is needed, the device positioning key is deactivated, allowing the device to be moved easily for handling and placement. After placement, the foot control button is activated to fix the device to the ground. At this point, the support arm positioning key 29 is activated, activating the controllable gas spring installed in the support arm 28, allowing the support arm 28 to rotate easily. When the support arm 28 reaches the designated position, the support arm positioning key 29 is deactivated, locking the support arm 28. This allows for easy adjustment of the hanging bracket 3 position, accommodating students of different heights and habits, and facilitating convenient access to various mobile phones during practical operations.
[0040] The foot pedal 13 is also equipped with switches for controlling the lifting drive device and the pitch angle adjustment drive device 24. The foot pedal 13 is a multimedia wireless foot pedal 22, which communicates wirelessly with the control system 18 via Wi-Fi or Bluetooth. The simulation operation device also includes a teaching pendant and a shadowless lamp. The foot pedal 13 is also equipped with a teaching pendant control switch for zooming and focusing, and a shadowless lamp control switch for controlling the brightness of the shadowless lamp. The teaching pendant control switch and the shadowless lamp control switch communicate with the teaching pendant and the shadowless lamp via Wi-Fi or Bluetooth, respectively. It communicates with the multimedia teaching system on the independent head-simulating model 7 device via 4G network or Bluetooth. The multimedia wireless foot pedal 22 controls the magnification of the multimedia teaching pendant and the brightness of the shadowless lamp, avoiding the use of wires, facilitating the separate handling and placement of the equipment, and eliminating manual operation, thus improving convenience. The multimedia wireless foot pedal 22 completes the lifting and pitching of the equipment, eliminating manual operation and improving convenience.
