一种角膜屈光手术开睑固定器
By designing a blepharoplasty fixator that combines a fixing plate with an elastic band and a slider structure, the problems of unstable hand-held operation and patient cooperation in existing technologies have been solved. This achieves stable fixation without the need for hand-held operation and adapts to different face sizes, thus improving the success rate of the surgery.

AI Technical Summary
The existing eyelid fixation device requires an assistant physician to hold it in place during use, and the patient must keep their head still. This can easily cause the device to shake due to tension or unstable holding, affecting the smooth progress of the surgery. Furthermore, the different face sizes of different patients increase the difficulty of fixation.
A corneal refractive surgery eyelid fixation device was designed. The fixation plate contacts the patient's forehead, and the elastic band and slider structure stabilize the fixation plate and the patient's head. The slider slides on the arc-shaped slide rail to adjust the position of the eyelid hook to adapt to different patients' face sizes.
It enables the eyelid speculum to be stabilized without the doctor holding it, reducing the difficulty of the surgery, avoiding shaking, adapting to different patients' face sizes, and improving the success rate of the surgery.
