[0026] According to a first aspect of the present invention, a dental teaching system is provided, which includes a case 1 , a human body model 2 and a connecting component 3 .

[0027] Hereinafter, the specific structures of the above-mentioned components of the dental teaching system according to the present embodiment will be described.

[0028] In this embodiment, if Figure 1 and Figure 2As shown, the connecting assembly 3 is formed as a strip structure as a whole and is respectively connected to the chassis 1 and the human body model 2; a first driving assembly is installed in the chassis 1, and the first driving assembly is used to adjust the height of the human body model 2, that is, the height position of the human body model 2 relative to the ground or the chassis 1, wherein the first driving assembly includes a first driving member 11, a first rotating member 12 and a first rotating seat 13, and the first driving member 11 can be a motor or a cylinder or other mechanism as long as it can drive the first rotating member 12.

[0029] The first rotating member 12 can be formed into a bar-shaped rod structure, and the two ends of the first rotating member 12 in the length direction are rotatably connected to the first driving member 11 and the first rotating seat 13 respectively; the first rotating member 12 can also be formed into a cylindrical, plate-shaped or disc-shaped structure.

[0030] like Figures 1 to 6 As shown, a second drive assembly is installed in the human body model 2, and the second drive assembly is used to adjust the body position of the human body model 2, that is, the body position of the patient during the rotation process from upright to lying down. The second drive assembly includes a second rotating member 22 and a second rotating seat 23. The second rotating member 22 can rotate relative to the second rotating seat 23. The second rotating member 22 can be formed into a rotating shaft structure, and the first rotating seat 13 and the second rotating seat 23 can both be formed into a block or plate structure; the connecting assembly 3 includes a first connecting member 31 and a second connecting member 32, and the first connecting member 31 and the second connecting member 32 are both formed into a strip structure.

[0031] In this embodiment, if Figures 1 to 6 As shown, the first rotating base 13 is mounted on the chassis 1. The first rotating base 13 can be mounted on the housing of the chassis 1. For example, a rotating hole is formed on the chassis 1, and the first rotating base 13 is fixed in the rotating hole. The first rotating member 12 can extend from the interior of the chassis 1 through the rotating hole, so as to form a rotational cooperation relationship between the first rotating base 13 and the first rotating member 12. In other optional embodiments, the first rotating base 13 is formed on the housing of the chassis 1, so that the first rotating base 13 and the chassis 1 are integrally formed, and the first rotating base 13 is formed with a rotating hole for the first rotating member 12 to extend.

[0032] Specifically, if Figure 1 and Figure 2 As shown, the first driving member 11 drives one end of the first rotating member 12. The other end of the first rotating member 12 is rotatably engaged with the first rotating base 13 and fixedly connected to one end of the first connecting member 31. In this way, the first connecting member 31 and the first rotating member 12 can rotate synchronously under the drive of the first driving member 11. The other end of the first connecting member 31 is rotatably connected to the second rotating member 22. The second rotating base 23 is mounted on the outer surface of the human body model 2, specifically, it can be mounted on the side of the human body model 2. The second rotating member 22 passes through the opening in the second rotating base 23 and is rotatably connected to the first connecting member 31.

[0033] like Figures 1 to 6 As shown, a protruding first connecting portion 131 is provided on the first rotating seat 13, and a protruding second connecting portion 231 is provided on the second rotating seat 23. The second connecting member 32 rotates with the first connecting portion 131 and the second connecting portion 231 respectively, so that in the process of the first driving member 11 driving the first connecting member 31 to rotate, the relative position relationship between the second connecting member 32 and the first connecting member 31 changes, so that the relative position relationship between the first rotating seat 13 and the second rotating seat 23 changes, but the second rotating seat 23 does not rotate during the change of the position relationship, so that the direction of the second rotating seat 23 itself is always guaranteed to remain unchanged.

[0034] In this way, when the first driving member 11 drives the first rotating member 12, the first connecting member 31 moves synchronously with the first rotating member 12, so that the connecting component 3 rotates relative to the chassis 1, and the first rotating seat 13 and the second rotating seat 23 do not rotate, so that the second rotating seat 23 moves up and down relative to the chassis 1 only under the drive of the rotation of the connecting component 3, so that the first driving member 11 can adjust the height position of the human body model 2, and the upright or lying position of the human body model 2 at different angles is not affected by the first driving member 11, thereby avoiding the connecting component 3 from blocking the human body model 2 or interfering during treatment, thereby meeting teaching needs.

[0035] In this embodiment, if Figure 1 and Figure 2 As shown, the first connecting part 131 or the second connecting part 231 is formed as a nail body that is detachably connected to the first rotating seat 13 or the second rotating seat 23, and a long hole is provided on the first connecting member 31. The first connecting part 131 or the second connecting part 231 passes through the connecting hole on the second connecting member 32 and the long hole on the first connecting member 31 to be connected to the first rotating seat 13 or the second rotating seat 23, thereby realizing the assembly of the connecting component 3 and the chassis 1; in other optional embodiments, the first connecting part 131 or the second connecting part 231 can be formed as a short pin structure and be integrally formed with the first rotating seat 13 or the second rotating seat 23.

[0036] In addition, in this embodiment, Figure 2 As shown, the connection assembly 3 further includes a protective cover arranged around the outside of the second connection member 32 and the first connection member 31 , and the protective cover is formed into a shell structure.

[0037] Furthermore, in this embodiment, Figure 4 and Figure 6As shown, the second drive assembly also includes a fixing member 24, a support member 25 and a second drive member 21. The fixing member 24 and the support member 25 can both be formed into a bracket structure; the fixing member 24 is fixedly mounted on the second rotating member 22, and the second drive member 21 is fixedly mounted on the fixing member 24. The second drive member 21 can be a motor or a cylinder mechanism, as long as it can provide power for adjusting the body position of the human body model 2; the support member 25 is rotatably mounted on the second rotating member 22, and the support member 25 can be hinged to the second rotating member 22. The human body model 2 includes a head mold 201 mounted on the support member 25, which is used to simulate the patient's head. The second drive member 21 can drive the support member 25 to rotate around the second rotating member 22, so that the angle between the head mold 201 and the fixing member 24 changes, thereby simulating different body positions of the patient.

[0038] In a preferred embodiment, Figure 4 and Figure 6 As shown, the second drive assembly also includes a matching assembly, so that the second drive member 21 does not directly drive the support member 25 to rotate, ensuring smooth driving. Specifically, the matching assembly includes a screw rod 26 with an external thread on the outer wall and a matching member 27 that is threadedly matched with the screw rod 26. A threaded hole that matches the external thread is formed on the matching member 27. The matching member 27 is installed on the support member 25. The matching member 27 is preferably formed into a block-shaped, columnar or rod-shaped structure, so that the two end faces of the matching member 27 facing each other are connected to the support member 25 to improve the connection reliability and achieve smooth movement; the second drive member 21 drives the screw rod 26 to rotate, so as to drive the matching member 27 to move along the extension direction of the screw rod 26, and under the action of the support member 25 and the matching member 27 moving together, the support member 25 drives the head mold 201 to rotate.

[0039] In addition, in this embodiment, Figures 1 to 8 As shown, a dental mold 202 is provided in the head mold 201 for simulating the conditions in the patient's oral cavity. Specifically, the dental mold 202 includes a base 203 and teeth 204. The base 203 is provided with pits for the roots of the teeth 204 to extend into. The teeth 204 are detachably connected to the base 203 to facilitate maintenance and replacement. The teeth 204 and the base 203 can be detachably connected by fasteners such as screws. In other optional embodiments, the teeth 204 can be directly pulled out from the base 203, and no fasteners are provided to fasten the two. For example, the teeth 204 can be connected to the base 203 by an interference fit.

[0040] In this embodiment, the number of teeth 204 may be one. Preferably, a plurality of teeth 204 are provided to simulate teeth 204 at different positions in the patient's oral cavity for the trainee to operate.

[0041] like Figure 7 and Figure 8As shown, the teeth 204 include operating teeth 205. When there is only one tooth 204, the tooth 204 is the operating tooth 205. When there are multiple teeth 204, all teeth 204 can be operating teeth 205, or one or more of all teeth 204 can be operating teeth 205.

[0042] Specifically, the operating tooth 205 is provided with a groove 206, within which is disposed a grindable filler 208. The filler 208 can be made of a resin material or other material. Filler 208 can be ground using a dental instrument (e.g., a dental handpiece) to simulate grinding the patient's tooth 204. It should be noted that the filler 208 can be replaced after grinding, eliminating the need to replace the operating tooth 205 or the dental mold 202, thus saving costs.

[0043] More specifically, the number of the grooves 206 on the operating tooth 205 can be one or more.

[0044] Preferably, the groove 206 is formed on the crown of the operating tooth 205. The crown is the visible portion of the tooth located above the gum line. Specifically, the groove 206 can be formed by an inward depression on the maxillary surface of the crown (i.e., the occlusal surface where the upper and lower teeth meet), the labial and buccal surface of the crown, the lingual and palatal surface of the crown, the mesial surface of the crown, or the distal surface of the crown. It should be noted that if there are multiple grooves 206 on the operating tooth 205, the multiple grooves 206 can be provided on the same or different surfaces of the crown.

[0045] Furthermore, in this embodiment, Figures 7 to 9 As shown, a sensor assembly 210 is disposed within the groove 206 and sandwiched between at least a portion of the filler 208 and the operating tooth 205, allowing the trainee to trigger the sensor assembly 210 when grinding the filler 208. A lead hole 207 is formed on the wall of the groove 206 and passes through the operating tooth 205. The lead hole 207 can extend from the bottom of the groove 206 toward the root of the tooth 204. The cable of the sensor assembly 210 is passed through the lead hole 207 and connected to the control unit, allowing the sensor assembly 210 to feed back the detected signal to the control unit. The control unit can be a controller installed in the housing.

[0046] Specifically, in this embodiment, Figures 7 to 9As shown, the sensor assembly 210 includes a mounting member 211 and a conductor sensing unit 212. The mounting member 211 is formed into an annular structure. The conductor sensing unit 212 is attached to the annular inner surface of the mounting member 211. At least part of the filler 208 is arranged inside the mounting member 211 and contacts the conductor sensing unit 212. When the dental instrument wears through the filler 208, causing the drill bit on the dental instrument to contact the conductor sensing unit 212, or when liquid is introduced after the filler 208 is worn through and contacts the conductor sensing unit 212, the sensor assembly 210 will be triggered to issue a sensing signal to warn that the filler 208 is worn through, indicating that there may be a risk of over-wear.

[0047] More specifically, if Figure 9 As shown, the conductor sensing unit 212 includes a plurality of first polarity members and a plurality of second polarity members. The first polarity members and the second polarity members can be metal contacts connected to the positive and negative poles respectively. The polarities of the first polarity members and the second polarity members are opposite and are alternately arranged around the mounting member 211. When the dental instrument wears through the filling 208, so that the first polarity members and the second polarity members are connected, the conductor sensing unit 212 transmits the sensing signal to the control unit.

[0048] It should be noted that the first and second polarity members can be connected by a dental instrument or liquid simultaneously contacting the first and second polarity members. The width and / or spacing between the first and second polarity members can be adjusted to facilitate connection between the first and second polarity members by the dental instrument after the filler 208 is worn through.

[0049] Furthermore, in this embodiment, Figures 1 to 9 As shown, the sensing assembly 210 also includes a pressure sensing unit 213, which can be a thin film pressure sensor. The pressure sensing unit 213 is disposed on the outer surface of the mounting member 211 and is capable of contacting the wall of the groove 206. When excessive force is applied, the pressure sensing unit 213 is squeezed, causing the pressure sensing unit 213 to feed back a pressure signal to the control unit. The pressure sensing unit 213 can be disposed on the annular outer surface of the mounting member 211, or it can be mounted on the end of the mounting member 211 facing the bottom of the groove 206.

[0050] In a preferred embodiment, the control unit is communicatively connected to the second driving member 21, so that when the sensor component 210 sends a signal to the control unit, the control unit can drive the second driving member 21 to drive the head model 201 to move, for example, repeatedly move in a small range, to simulate the situation where the patient's head moves due to pain during pressure treatment, thereby improving the authenticity of the simulation of the dental teaching system, being closer to actual treatment surgery, and helping to improve the students' operational level. The dental teaching system according to the present invention comprises a chassis, a human body model and a connecting assembly connecting the chassis and the human body model; a first driving assembly is installed in the chassis, the first driving assembly comprises a first driving member, a first rotating member and a first rotating seat; a second driving assembly is installed in the human body model, the second driving assembly comprises a second rotating member and a second rotating seat; the connecting assembly comprises a first connecting member and a second connecting member; the first rotating seat is installed in the chassis; the first driving member drives one end of the first rotating member, the other end of the first rotating member rotates with the first rotating seat and is fixedly connected to one end of the first connecting member, and the other end of the first connecting member is rotatably connected to the second rotating member; a first rotating seat is provided with A protruding first connecting portion is provided, and a protruding second connecting portion is provided on the second rotating seat, and the second connecting member is respectively rotatably matched with the first connecting portion and the second connecting portion; when the first driving member drives the first rotating member, the first connecting member and the first rotating member move synchronously to realize the rotation of the connecting component relative to the chassis, and the first rotating seat and the second rotating seat do not rotate, so that the second rotating seat moves up and down relative to the chassis only under the rotation of the connecting component, so that the first driving member can adjust the height position of the human body model, and the upright or lying position of the human body model is not affected by the first driving member, thereby avoiding the connection component from blocking the human body model or interfering during treatment, thereby meeting teaching needs. According to a second aspect of the present invention, a dental teaching simulation method is provided, which is implemented using the dental teaching system described above.

[0051] The height of the human body model 2 is adjusted by driving the first driving member 11 and / or the position of the human body model 2 is adjusted by driving the second driving member 21 so as to adjust the human body model 2 to a suitable height and posture.

[0052] Dental treatment is simulated using a dental instrument, which may be a dental handpiece or a dental scaler. When the dental instrument is working, the sensor component 210 is triggered, and the sensor component 210 can transmit the detected sensing signal to the control unit.

[0053] It should be noted that the triggering of the sensor component 210 includes at least one of the following three ways: the dental instrument triggers the conductor sensing unit 212, the liquid contacts the conductor sensing unit 212 when the dental instrument is working, or the pressure sensing unit 213 is triggered due to excessive force.

[0054] At this time, the control unit can output a simulation signal to the second driving member 21, so that the second driving member 21 drives the head model 201 to move, so as to simulate the head movement of the patient when the patient feels pain during dental treatment, making the teaching more realistic.

[0055] Furthermore, the second driving member 21 drives the head mannequin 201 to move, specifically by causing the second driving member 21 to repeatedly shake the head mannequin 201 one or more times. It should be noted that one deflection and then return of the head mannequin 201 counts as one repeated shaking. Preferably, the second driving member 21 repeatedly shakes the head mannequin 201 once for a total duration of ≤ 2 seconds, thereby achieving rapid repeated shaking, more realistic, and enhancing simulation realism.

[0056] The dental teaching simulation method of the present invention can simulate the head movement of the patient when in pain during dental treatment, making the dental teaching system more realistic during use and close to the actual treatment situation, which is conducive to improving the skills of students.

[0057] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
