[0002] In oral diagnosis and treatment, due to the limited space of the oral cavity, medical staff cannot directly visualize the surgical area. Therefore, it is common practice for dentists to use a handheld mouth mirror to obtain a clear image of the surgical area. However, for patients requiring periapical surgery, the mouth mirror cannot enter the surgical area due to the limited size of the window, making it impossible to accurately observe the internal condition and the status of root canal retrograde filling. For patients with limited mouth opening, especially when treating the posterior teeth, even a normal-sized mouth mirror is difficult to enter, affecting treatment efficiency and results. During the diagnosis and treatment, auxiliary instruments such as probes and excavators are needed for examination. Medical staff need to repeatedly replace the mouth mirror and auxiliary instruments, which is cumbersome and affects the efficiency of diagnosis and treatment. Summary of the Invention
