Description

Technical Field

[0001] This utility model relates to the field of oral clinical teaching devices, and more specifically, to a dental dual-person simulation teaching device. Background Technology

[0002] In the process of dental treatment simulation teaching, in order to reach certain areas of the simulated head model, the instructor often needs to tilt his body into a hunched or other uncomfortable position, bend his wrists into an awkward angle, and usually needs to maintain this posture for a long time, which puts a lot of physical stress on the instructor.

[0003] The existing training for dental clinicians mainly relies on traditional methods such as watching instructional videos or observing patients in person, supplemented by some individual simulation head model operations. This lacks practical application, and trainees often need to undergo real clinical practice to truly master various techniques, which poses a significant risk to patients.

[0004] Therefore, this application proposes a dental dual-person simulation teaching device. Utility Model Content

[0026] Example:

[0027] Please see Figure 1-4 A dental dual-person simulation teaching device includes a dental workbench 1. Two symmetrically distributed instrument arms 2 are installed on the upper end of the dental workbench 1. Instrument arms 3 are rotatably connected to the ends of instrument arms 2. A surgical light 31 is installed at the lower end of instrument arms 3. An operation panel 32 is rotatably connected to the side end of instrument arms 2. A lifting rod 4 is installed at the inner bottom end of the dental workbench 1. A support plate 5 is fixedly connected to the upper end of the lifting rod 4. A handle 6 is installed on the side end of the support plate 5. An upper limb model 7 and a head model 8 are provided on one side of the support plate 5. A loading component is installed between the upper limb model 7, the head model 8 and the support plate 5.

[0028] In order to enable existing dental clinicians to better conduct simulated practical operations during the use of this solution, in this embodiment, the operator can place the dental membrane to be simulated and tested into the head mold 8, and then fix the upper limb model 7 and head mold 8 to the surface of the support plate 5 by the action of the loading component. Subsequently, during the operation, the support plate 5 can be moved up and down to the appropriate position by activating the lifting rod 4. Finally, the handle 6 can be rotated according to the angle of dental membrane observation required by the operator, so that the upper limb model 7 and head mold 8 can be flipped over as a whole for easy movement by the operator. The second instrument arm 3 enables the surgical light 31 to properly illuminate the dental membrane of the head model 8 for observation. During the observation process, the operator can also make slight movements of the upper limb model 7 and the head model 8 under the action of the loading component, which facilitates the fine adjustment of the position of the observed dental membrane during actual operation. Compared with the existing technology, this solution realizes the free adjustment of the height and pitch angle of the simulated head model during actual operation, increasing the practicality and application flexibility of the dental simulation teaching head model dental chair. At the same time, under the action of the loading component, the upper limb model 7 and the head model 8 can be conveniently loaded, unloaded and replaced.

[0029] Please see Figure 1 and Figure 4 The front end of the support plate 5 has a groove 51. A damping shaft 52 is rotatably connected between the inner walls of the groove 51. One end of the damping shaft 52 extends through to the outside of the groove 51. A flip plate 53 is fixedly connected to the outer end of the damping shaft 52. The flip plate 53 is located between the inner walls of the groove 51. The damping shaft 52 is fixedly connected to the handle 6.

[0030] During use, when personnel need to adjust the tilt angle of the head model, they can turn the handle 6 to cause the damping shaft 52 to drive the flip plate 53 to rotate. Then, the loading components installed on the upper and lower sides of the flip plate 53, as well as the upper limb model 7 and head model 8, can rotate simultaneously. Under the action of the damping shaft 52, the effect of stopping immediately can be achieved, which greatly facilitates practical simulation operations.

[0031] Please see Figure 1-3 The lower jaw of the head mold 8 is fitted with a connecting sleeve 81. The lower end of the connecting sleeve 81 is provided with a spherical groove 82. A ball bearing 83 is rotatably connected between the inner walls of the spherical groove 82. One end of the ball bearing 83 is fixedly connected to a connecting sleeve 84. The lower end of the connecting sleeve 84 is provided with a slot 85. The side end of the connecting sleeve 84 is provided with a positioning groove 86. The positioning groove 86 and the slot 85 are interconnected.

[0032] In use, the head mold 8 has a connecting sleeve 81 embedded in the lower jaw end, and a ball bearing 83 is rotatably connected in a spherical groove 82. The slot 85, which is fixedly connected to one end of the ball bearing 83, is fitted on the outside of the connecting rod 97. This allows the connecting rod 97 to pass through the inner wall of the slot 85 after the loading component is inserted into the upper limb model 7. Once the appropriate position is reached, the operator rotates the positioning torsion block 98 until it fits against the inner wall of the positioning groove 86, thus locking the connecting rod 97 within the inner wall of the slot 85. In actual simulation operations, the head mold 8 can also be adjusted at a micro-angle due to the setting of the ball bearing 83, which allows the operator to observe the dental membrane inside the head mold 8 in more detail.

[0033] Please see Figure 1-4 The loading assembly includes positioning frames 91 on the upper and lower sides of the flip plate 53. The lower end of the positioning frame 91 is threadedly connected to a screw 92, and the upper end of the screw 92 is fixedly connected to a positioning block 93. Crossbars 94 are inserted on both sides of the lower end of the screw 92. A connecting sleeve 3 96 is installed at the front end of the positioning frame 91. A connecting rod 97 is installed at the front end of the connecting sleeve 3 96. A positioning torsion block 98 is threadedly connected to the side end of the connecting rod 97. The connecting rod 97 extends through to the inside of the upper limb model 7.

[0034] Furthermore, one end of the connecting sleeve 3 96 is provided with a spherical groove 2 961, and a ball 2 971 is rotatably connected between the inner walls of the spherical groove 2 961. One end of the ball 2 971 is fixedly connected to the connecting rod 97.

[0035] In the process of using this solution, the positioning frame 91 is first placed on the upper and lower sides of the flip plate 53. Then, the horizontal bar 94 is rotated at the bottom to cause the screw 92 to move upward continuously until the positioning block 93 is attached to the lower surface of the flip plate 53. At this time, the positioning frame 91 is fixed to the surface of the flip plate 53. Then, the connecting rod 97 is inserted between the inner walls of the upper limb model 7 and the end reaches the inner wall of the slot 85. Finally, the positioning torsion block 98 is selected until it is attached to the inner wall of the positioning groove 86. At this time, the upper limb model 7 and the head model 8 are fixed to the surface of the flip plate 53 under the action of the loading component. The tilt angle can be adjusted accordingly according to the rotation of the flip plate 53.

[0036] Furthermore, under the action of spherical groove 2 961 and ball bearing 2 971, the upper limb model 7 can also make micro-angle position adjustments after installation, which is beneficial for operators to adjust and observe the details during the simulation process.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
