Microscopic mouth mirror with changeable angle

Abstract

The invention relates to an angle-changeable microscopic mouth mirror which comprises a handle, a lens holder and a lens, the lens holder is arranged at the front end of the handle, a concave cavity is formed in the lens holder, the lens is installed in the concave cavity, a universal adjusting mechanism is arranged in the concave cavity, and the lens is installed on the universal adjusting mechanism; the universal adjusting mechanism comprises a ball socket seat, a ball head rod and a jacking assembly, the ball socket seat is fixed to the center of the inner bottom face of the lens holder, a ball head of the ball head rod is embedded in the ball socket seat, friction damping exists between the ball head and the ball socket seat, and the other end of the ball head rod is connected to the center of the back face of the lens; the jacking assembly comprises a guide pipe column, an ejector rod, an elastic bending linkage wire and a spring button. The universal adjusting mechanism is arranged in the concave cavity of the lens support, and the lens is mounted on the universal adjusting mechanism, so that the reflection angle of the lens can be flexibly adjusted to enable a doctor to obtain a good visual field, a patient can be treated in a comfortable body position, the working difficulty of the doctor is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an oral mirror used for oral examination and treatment, in particular to a microscopic oral mirror whose angle can be changed, and belongs to the technical field of oral medical appliances. Background technique [0002] In recent years, microscopic treatment technology in the Department of Stomatology has developed rapidly. Compared with traditional treatment, microscopic treatment can magnify the affected part of the tooth more times, so that clinicians can observe the affected part more clearly, confirm the operation position, and reduce the risk of dental surgery. Treatment uncertainty, improve treatment quality, reduce trauma. However, the current dental microscopes are huge in size. In microtherapy operations, due to the different positions of the teeth, it is necessary for the doctor to use a microscopic mirror to reflect the situation of the teeth. However, due to the limitations of the current microscope and microscopic...

Problems solved by technology

However, the current dental microscopes are huge in size. In the microtherapy operation, due to the different positions of the teeth, it is necessary for the doctor to use a microscopic mirror to reflect the situation of the teeth. However, due to the limitations of the current microscope and the microscopic The angle cannot be changed. In order to obtain a good field of view, the patient's posture is very demanding. Patients often need to be treated in an uncomfortable position for a long time. If they move slightly, the field of view in the microscope will shift, especially For the observation of the maxillary posterior teeth, it is very difficult for the operator to adjust his body position again and again if he moves slightly.

[0003] Therefore, it is necessary to develop a microscopic mouth mirror that can change the angle, which can solve the uncomfortable problem of the patient's long-term fixed position, and allow the patient to receive treatment in a comfortable position.
