AI Technical Summary
In existing eye-gazing devices, the fixed LED light strips are not easy to move, resulting in large errors in the accuracy of eye tumor localization and inaccurate beam treatment positions.
The device employs a gaze mechanism to drive the horizontal plate to rotate, and a moving mechanism to move the LED light along the length of the horizontal plate. By controlling the motor to drive the lead screw and slide, the precise displacement of the LED light is achieved, and a buzzer is provided to improve the patient's focusing efficiency.
It improves the accuracy of eye tumor localization and beam therapy, reduces localization errors, and enhances the patient's focusing efficiency and precision.
