Eyelid edge gray line cutting blade with eyeball gaze fixing function

The utility model provides an eyelid edge gray line cutting blade with an eyeball gaze fixing function and belongs to the field of mechanical devices. The specific technical scheme adopted by the utility model is that symmetrical double-sided cutting edges are arranged at the head of a blade body, and scales are arranged on the blade body. The scales take millimeter as a unit and are arranged at equal distances and symmetrically arranged on the front surface and the back surface of the blade body. A memory steel wire with elasticity is arranged at the tail part of the blade body; the tail end of the steel wire is expanded to be spherical and taken as a mark for fixing a gaze. As the double-sided cutting edges are arranged, when the eyelid edge gray line cutting operation is performed, an eyelid edge can be cut forwards or backwards according to the operation demands without reversely rotating the cutting edge or replacing a knife, so that the operation time is shortened, and the pain of a patient is reduced; as the blade body is provided with the scales taking the millimeter as the unit, the specific depth of the knife can be directly observed, and the cutting depth can be mastered. As a gaze fixing device is arranged at the tail end of the blade body, eyeballs of the patient can rotate in a certain direction and remain the fixed gaze to facilitate operation.
