[0037] Referring to Figures 1 to 6 , an oral suture knotting basic skill trainer is provided in an embodiment of the present application, including a base 1, an adjusting mechanism 2, and a training structure 3. The adjusting mechanism 2 includes a connecting block 204 with a rotating function, and the adjusting mechanism 2 is fixedly connected to the upper surface of the base 1. The training structure 3 includes a fixed seat 307 fixedly connected to the outer surface of the connecting block 204. One end of the fixed seat 307 is fixedly connected to a fixing plate 302, and the other end of the fixed seat 307 is slidably connected to a connecting rod 308.

Oral models 303 are movably connected to the outer surfaces of the fixing plate 302 and the rotating plate 306, and magnetic blocks 101 are fixedly connected to the four corners of the lower surface of the base 1.

[0038] A rotating shaft 315 penetrates through the outer surface of the connecting rod 308, and the outer surface of the rotating shaft 315 is rotatably connected to the outer surface of the fixed seat 307. One end of the rotating shaft 315 passes through the outer surface of the fixed seat 307 and is fixedly connected to a gear 309.

[0039] A stop rod 310 is meshed with the outer surface of the gear 309. The lower end of the stop rod 310 is fixedly connected to a slider 312. The outer surface of the stop rod 310 is slidably connected to a limit frame 311. The outer surface of the limit frame 311 is fixedly connected to the outer surface of the fixed seat 307, and the outer surface of the slider 312 is slidably connected to the inner wall of the limit frame 311.

[0040] A spring 313 is fixedly connected to the inner wall of the limit frame 311. The other end of the spring 313 is fixedly connected to the lower surface of the slider 312. The outer surface of the limit frame 311 is fixedly threadedly connected to a third locking bolt 314, and the other end of the third locking bolt 314 is in contact with the outer surface of the slider 312.

[0041] The training structure 3 further includes a battery compartment 305. The outer surface of the battery compartment 305 is electrically connected to a switch 4 through a wire. The switch 4 is fixedly connected to the outer surface of the rotating plate 306. The other end of the switch 4 is connected to a fill light 304 through a wire. The fill light 304 is fixedly connected to the upper surface of the fixing plate 302. And an elastic band 301 is fixedly connected to the outer surface of the fixing plate 302. The other end of the elastic band 301 is fixedly connected to the outer surface of the rotating plate 306. Place the base 1 on the table, and then rotate the third locking bolt 314 so that the slider 312 can slide within the limit frame 311. Then hold the fixing plate 302 and the rotating plate 306 with both hands, and pull the rotating plate 306 to make the connecting rod 308 rotate around the rotating shaft 315, thereby increasing the angle between the fixing plate 302 and the rotating plate 306, facilitating the simulation of the human mouth opening, and thus facilitating students to perform knotting simulation training on oral models 303 with different opening angles.

[0042] Refer to Figures 1 to 6 , in one aspect of this embodiment, the adjusting mechanism 2 further includes a support frame 201 fixedly connected to the upper surface of the base 1. A rotating block 202 is rotatably connected to the outer surface of the support frame 201.

Rotate the first locking bolt 203 so that the lower end of the first locking bolt 203 separates from the outer surface of the connecting block 204, thereby enabling the connecting block 204 to rotate around the rotating block 202. At the same time, rotate the second locking bolt 205 so that one end of the second locking bolt 205 separates from the outer surface of the rotating block 202, thereby enabling the rotating block 202 to rotate on the outer surface of the support frame 201, which facilitates adjusting the angle of the training structure 3 to a certain extent.

[0045] All electrical devices in this solution are powered by an external power supply.

[0046] Working principle: When in use, first place the base 1 on the table, and then rotate the third locking bolt 314 so that the third locking bolt 314 separates from the outer surface of the slider 312. As a result, the slider 312 can slide within the limit frame 311. Then, hold the fixed plate 302 and the rotating plate 306 with both hands, and pull the rotating plate 306 to make the connecting rod 308 rotate around the rotating shaft 315. When the connecting rod 308 rotates, it drives the gear 309 to rotate, thereby causing the blocking rod 310 to slide downward. The downward sliding of the blocking rod 310 drives the slider 312 to slide on the inner wall of the limit frame 311, compressing the spring 313. When the fixed plate 302 and the rotating plate 306 are adjusted to the appropriate angle, the spring 313 rebounds and drives the slider 312 to slide upward, causing the blocking rod 310 to engage with the gear 309 again. Then, rotate the third locking bolt 314 again so that one end of the third locking bolt 314 closely fits the outer surface of the slider 312, facilitating the limitation of the slider 312. Furthermore, the included angle between the fixed plate 302 and the rotating plate 306 is increased, causing the elastic band 301 to deform, facilitating the simulation of the human mouth opening, and thus facilitating the user to perform knot-tying simulation training on models with different oral opening angles.

[0047] During training, rotate the first locking bolt 203 so that the lower end of the first locking bolt 203 separates from the outer surface of the connecting block 204. As a result, the connecting block 204 can rotate around the rotating block 202. When adjusted to the appropriate angle, rotate the first locking bolt 203 in the opposite direction so that the lower end of the first locking bolt 203 fits the outer surface of the connecting block 204 again, facilitating the limitation of the connecting block 204. At the same time, rotate the second locking bolt 205 so that one end of the second locking bolt 205 separates from the outer surface of the rotating block 202. As a result, the rotating block 202 can rotate on the outer surface of the support frame 201, facilitating the adjustment of the angle of the training structure 3 to a certain extent, and facilitating the students to select an appropriate angle to operate on the oral model 303, improving the success rate of students' knot-tying to a certain extent. When the classroom light is dim, turning on the supplementary light 304 facilitates the supplementary lighting of the outer surfaces of the fixed plate 302 and the rotating plate 306, thus facilitating the students to train in a dim environment and increasing the diversity of usage scenarios.
