Adjustable expanding device for ophthalmology department and adjusting method thereof

Abstract

The invention discloses an adjustable expanding device for the ophthalmology department and an adjusting method of the adjustable expanding device, and belongs to the technical field of medical auxiliary equipment. An adjustable expanding device for the ophthalmology department comprises a base table, a positioning frame arranged in a positioning hole in a sliding mode, and an annular suction cup fixedly arranged at the bottom of the base table. A driving ring is rotatably arranged on the base station, and when the driving ring rotates, the two groups of expansion rings get close to each other or get away from each other; the cleaning block and the cleaning block are arranged on the positioning frame, and the driving part is used for driving the positioning frame to slide; a doctor adjusts the expansion range of the expansion ring according to needs, so that the device is better suitable for different patients and cleans eyeballs in an operation, the safety and the success rate of the operation are guaranteed, meanwhile, by means of the wrapping type suction cup, the device can be better attached to the periphery of the eyes while the base table is prevented from shaking and the safety is improved, cleaning liquid is prevented from overflowing, and the cleaning effect is improved. And the operation comfort of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an adjustable ophthalmic expansion device and an adjustment method thereof. Background technique [0002] "Myopia laser surgery" is often referred to as "excimer laser surgery". AIER uses an excimer laser to perform refractive ablation of the stromal layer under the corneal flap, thereby reducing the corneal curvature in the pupil area and achieving the goal of correcting myopia. Purpose, in general, when performing eyeball surgery, due to the physiological response of the human body to close the eyes, it is usually necessary to open the eyelid by mechanical means to expose the eyeball to facilitate the operation. [0003] In the prior art, when expanding the opening and closing size of the eyelid, the precision of the expansion is difficult to control, and the equipment used for the expansion requires long-time support by personnel, and the cutting part of th...
