[0002] Dentistry is a medical discipline that studies the diagnosis, treatment and prevention of oral and maxillofacial diseases. Dentistry uses many auxiliary extension instruments, including mouth mirrors, mouth retractors and treatment instruments, which are the most basic instruments in oral examinations. In addition to reflecting light and pulling tissues, they can also help doctors observe the occlusal surfaces and adjacent surfaces of teeth that are not easy to see directly. In orthodontic examinations, mouth mirrors can assist in observing the overall arrangement of the dentition, and mouth retractors are used to retract the mouth angles and expand the opening range of the oral vestibule, which can help doctors better expose the operating site and avoid interference of the lips with the operating instruments.

[0003] When performing oral examination or treatment, a mouth mirror and a mouth retractor are used, and both need to be held in hand and used interchangeably. Existing instruments are inconvenient to fix individually and occupy both hands, resulting in the inability to operate other instruments when using a mouth mirror or a mouth retractor, affecting the doctor's operation of multiple instruments.

By providing the fixing rod 2111 and screwing the fixing rod 2111 into the mounting rod 2112, the hook body 2110 can be fixed.

[0045] The specific implementation of this embodiment is as follows: when it is necessary to place the hook body 2110 in the mouth, the servo motor 2102 can be started, and the servo motor 2102 can drive the frame 2101 to rotate, adjust the angular position of the hook body 2110, and then start the drive motor 2105.

The longer the mounting rod 2112 is, the farther the hook body 2110 will be from the guide block 2117, so that the guide block 2117 and the shell 2104 will not affect the doctor's line of sight, and the mounting rod 2112 can be unscrewed from the threaded tube 2113. After the mounting rod 2112 is unscrewed, the fixed rod 2111 can be unscrewed and the hook body 2110 can be replaced. After the hook body 2110 is installed in the mouth, the extension of the telescopic end of the double-piston cylinder 2115 can be used to determine the length of the mouth stretching, and various positions can be adjusted according to specific circumstances.

[0051] The specific implementation of this embodiment is as follows: when the mouth mirror needs to be used alone, the mouth mirror is clamped on the electric clamp 2205. According to the characteristics of the flexible metal rod 2206, the flexible metal rod 2206 is first pulled out from the storage slot 2202. According to the placement position of the mouth mirror, the flexible metal rod 2206 can be clamped in the fixing clamp 2204 to stabilize a part of the flexible metal rod 2206. According to the different positions of the flexible metal rod 2206, the slider 2217 moves on the sliding rod 2214 to change the position of the fixing clamp 2204 to adapt to the position of the flexible metal rod 2206. The fixing clamp 2204 can be rotated by the rotating shaft 2218 to adapt to the change in the angular position of the flexible metal rod 2206. After the position is adjusted, the small Cylinder 2220, the telescopic end of the small cylinder 2220 drives the splint 2221 to contract, and the splint 2221 fixes the rotating shaft 2218 to achieve the effect of fixing the fixing clamp 2204. The first micro motor 2212 and the second micro motor 2213 can be used to rotate the electric clamp 2205 at different angles to change the placement position and method of the mouth mirror. After the electric clamp 2205 is adjusted at multiple angles by the first micro motor 2212 and the second micro motor 2213, the mouth mirror is placed at a specified position in the oral cavity. Since the flexible metal rod 2206 close to the electric clamp 2205 is insufficient to stably support the electric clamp 2205, the multi-section telescopic rod 2210 can provide support for it to ensure that the mouth mirror is stably placed in the oral cavity.

[0056] The specific implementation of this embodiment is as follows: in order to avoid the hook clamping unit 21 and the mirror clamping unit 22 from affecting each other during use, the height position and the distance between the hook clamping unit 21 and the mirror clamping unit 22 can be adjusted, and the control instrument 310 is used to start the first electric push rod 307 and the second electric push rod 306. The first electric push rod 307 drives the frame 2101 to rise and fall through the first fixed shell 308, and the second electric push rod 306 drives the support plate 2201 to rise and fall through the mounting shell 305. The frame 210 The change of the height position will adjust the height of the hook body 2110, and the change of the height position of the support plate 2201 will adjust the overall height of the electric clamp 2205, and reduce the distance between the hook clamping unit 21 and the mirror clamping unit 22. The hook body 2110 is used to open the mouth, and then the electric clamp 2205 is used to clamp the mirror and put it into the mouth. They can be used at the same time. According to the different needs of using instruments during oral examination, the change of the overall height of the hook clamping unit 21 and the mirror clamping unit 22 can be met.
