By symmetrically installing two jaw arch plates 2 with adjustable spacing on the arc plate 1, the two jaw arch plates 2 with adjustable spacing and the tracing needle 22 can be flexibly adjusted according to the patient's oral morphology, thereby improving the accuracy and efficiency of restoration and improving the versatility and practicality of the device.
[0026] As a preferred embodiment of the present invention, four springs 3 are symmetrically arranged between the two jaw arch plates 2, and two of the springs 3 are symmetrically arranged between the two extension plates 20. Four springs 3 are symmetrically arranged between the two jaw arch plates 2, which enhances the stability and reliability of the device. Two of the springs 3 are symmetrically arranged between the two extension plates 20, which further ensures the stability and accuracy of the jaw arch plates 2 during the adjustment process.
[0027] As a preferred embodiment of the present invention, the driving mechanism comprises a square box 5 fixedly connected to the extension rod 4, wherein a meshing first bevel gear 56 and a second bevel gear 57 are provided in the square box 5, and a driving rod 40 coaxially fixed with the adjustment disk 41 is rotatably installed in the extension rod 4, and the driving rod 40 is coaxially fixed with the second bevel gear 57. A fixed shaft 55 is rotatably installed on the side wall of the square box 5, and the fixed shaft 55 is coaxially fixed with the first bevel gear 56. Through the meshing transmission of the bevel gears, the rotation of the adjustment disk 41 is realized, thereby driving the spacing adjustment of the jaw arch plate 2. The fixed shaft 55 rotatably installed on the side wall of the square box 5 is coaxially fixed with the first bevel gear 56, which provides a stable support and transmission path for the driving mechanism, and ensures the accuracy and stability of the transmission. This structure is compact in design, high in transmission efficiency, and easy to operate.
[0028] As a preferred embodiment of the present invention, a movable shaft 54 is provided inside the fixed shaft 55, and the movable shaft 54 is slidably connected to the fixed shaft 55 through a stopper 540 integrally formed on its outer wall. The movable shaft 54 can effectively increase the convenience of the fixed shaft 55 when rotating.
[0029] As a preferred embodiment of the present invention, a limiting tooth 51 is fixedly connected to the outer wall of the circumference of the movable shaft 54, and a limiting tooth groove 53 is provided on the outer wall of the square box 5 to be plugged with the limiting tooth 51. The plugged limiting tooth 51 and the limiting tooth groove 53 provide a stable limiting and positioning function for the movable shaft 54, preventing it from accidentally moving or falling off during use, and effectively preventing the adjusting disk 41 from rotating under the action of the spring 3.
[0030] As a preferred embodiment of the present invention, an adjusting knob 50 is fixedly connected to the outer end of the movable shaft 54, and a ring magnet 52 magnetically connected to the adjusting knob 50 is fixed on the outer wall of the square box 5. The adjusting knob 50 is provided to increase the convenience of rotating the movable shaft 54.
[0031] As a preferred embodiment of the present invention, a handle 6 is fixedly mounted on the outer wall of one end of the square box 5 away from the extension rod 4, and an anti-slip cover 60 is mounted on the outer wall of the handle 6. The handle 6 and the anti-slip cover 60 are provided to increase the convenience of holding the device.
[0032] When the plug-in Gothic arch tracing device for oral restoration of the utility model is used, first, the doctor or operator will hold the handle 6 of the device, and the anti-slip cover 60 provides a good grip to ensure that the device will not slip during operation. At this time, the two jaw arch plates 2 are in the initial position, with a moderate spacing, which is suitable for the oral morphology of most patients.
[0033] Next, the doctor will adjust the spacing of the jaw arch plate 2 according to the specific oral morphology of the patient. This step is achieved by operating the adjustment mechanism. Specifically, the doctor will turn the adjustment knob 50 fixed on the outer wall of the square box 5. Since the adjustment knob 50 is fixedly connected to the outer end of the movable shaft 54, the movable shaft 54 will rotate accordingly. The rotation of the movable shaft 54 will drive the rotation of the fixed shaft 55 and the first bevel gear 56. Since the first bevel gear 56 is meshed with the second bevel gear 57, the second bevel gear 57 will also rotate accordingly. The rotation of the second bevel gear 57 will eventually drive the drive rod 40 and the adjustment disk 41 coaxially fixed thereto to rotate.
[0034] The rotation of the adjustment disk 41 will change the relative position of the adjustment track 42 and the driving block 23 thereon. Since the driving block 23 and the extension plate 20 are integrally formed, and the extension plate 20 is connected to the movable groove 10 by sliding up and down, the driving block 23 will move along the adjustment track 42, thereby driving the extension plate 20 and the jaw arch plate 2 to adjust the spacing on the arc plate 1. In this process, the spring 3 plays a role of buffering and stabilization, ensuring the smooth movement of the jaw arch plate 2.
[0035] When the spacing of the jaw arch plate 2 is adjusted to a position suitable for the patient's oral morphology, the doctor can start the tracing operation. The tracing needle 22 on the tracing plate 21 will contact the patient's oral tissue and move with the movement of the jaw arch plate 2, thereby leaving clear tracing marks on the oral tissue. These marks will provide important reference for subsequent oral restoration operations.
[0036] During the entire operation, the cooperation between the limiting teeth 51 and the limiting tooth grooves 53 plays a key role. They can ensure that the movable shaft 54 will not accidentally move or fall off during the rotation process, thereby ensuring the accuracy and stability of the adjustment. At the same time, the magnetic connection between the annular magnet and the adjustment knob 50 also increases the convenience and comfort of operation.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
