[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] The embodiment of the present application discloses a novel oral scanning retractor. Figure 1-6 A new type of oral scanning retractor includes a pulling block 1 and a supporting rod 3. The supporting rod 3 includes a fixed rod 31, a hollow soft rod 32 and a connecting rod 33. A threaded rod 5 is rotatably provided inside the fixed rod 31. The outer side of the threaded rod 5 is threadedly connected to a threaded sleeve 6. A curved fixing frame 7 is slidably provided on the outer side of the threaded sleeve 6. The bottom of the curved fixing frame 7 is fixedly installed inside the fixed rod 31, and the top of the curved fixing frame 7 extends into the interior of the hollow soft rod 32 and is hinged with a connecting block 8 through a rotating shaft. The top of the connecting block 8 is fixedly installed inside the connecting rod 33, and the bottom of the connecting block 8 is hinged to the threaded sleeve 6. The top of the connecting rod 33 is detachably connected to a mounting seat 2, and the mounting seat 2 is fixedly connected to the bottom of the pulling block 1.

[0026] Here, by rotating the threaded rod 5, the threaded rod 5 can push the threaded sleeve 6 to move up and down, and the threaded sleeve 6 will push the connecting block 8 to rotate around the rotating shaft, so that the angle of the pulling block 1 can be adjusted, thereby improving the practicality of the device.

[0027] Reference Figure 1 and Figure 2 The shapes of the pull block 1 are divided into two types: crescent-shaped and spoon-shaped.

[0028] Reference Figure 2 、 Figure 3 and Figure 4 , when the pulling block 1 is arranged in the shape of a spoon head, it is divided into two sizes;

[0029] First, refer to Figure 2 and Figure 3 The top width of the cross-section of the pull block 1 is 1 cm and the bottom width is 2 cm. Here, by setting the pull block 1 to a size with a top cross-section width of 1 cm and a bottom width of 2 cm, the pull block 1 is more in line with the size of pulling the tongue side, and the size design is suitable for use on the tongue side.

[0030] Second, refer to Figure 2 and Figure 4 The top width of the cross-section of the pull block 1 is 2 cm and the bottom width is 4 cm. Here, by setting the pull block 1 to a size with a top cross-section width of 2 cm and a bottom width of 4 cm, the pull block 1 is more suitable for use with a retractor to pull the buccal side, and the size design is practical for the buccal side.

[0031] The pull block 1 is made of polycarbonate material or stainless steel material, and its surface is sprayed with black frosted resin paint.

[0032] Here, by making the pull block 1 of polycarbonate material or stainless steel, the durability and safety of the device can be improved, and it is convenient to clean and disinfect; at the same time, by spraying black resin coating on the surface, it can absorb more scattered light, without interfering with oral scanning and preventing distortion of the acquired image.

[0033] Reference Figure 6 The bottom of the fixed rod 31 is fixedly mounted with a handle 4, the bottom of the threaded rod 5 passes through the handle 4 and is fixedly connected with a turntable 51.

[0034] Here, a handle 4 is provided to facilitate holding the device, and a turntable 51 is fixedly connected to the bottom of the threaded rod 5 to facilitate driving the threaded rod 5 to rotate.

[0035] The implementation principle of a new oral scanning retractor in an embodiment of the present application is as follows: when in use, the staff uses it by holding the handle 4, and when in use, the turntable 51 can be rotated, and the turntable 51 drives the threaded rod 5 to rotate, and the threaded rod 5 can push the threaded sleeve 6 to move up and down, and the threaded sleeve 6 will push the connecting block 8 to rotate around the rotating shaft, so that the angle of the pull block 1 can be adjusted to make more space for the front side of the oral cavity, which is convenient for oral scanning, and the pull block 1 is made of polycarbonate material or stainless steel material, which can improve the durability and safety of the device and is convenient for cleaning and disinfection.
