Upper and lower eyelid adjusting device for Airy beam coherent elastography for conjunctiva detection

Abstract

The invention discloses an Airy beam coherent elastography upper and lower eyelid adjusting device for conjunctiva detection, and relates to the technical field of ophthalmology department auxiliary devices, the Airy beam coherent elastography upper and lower eyelid adjusting device comprises a fixing frame, an Airy beam mechanism, a fine adjustment mechanism, a connection moving mechanism and a mounting frame, an adjusting opening mechanism and an Airy beam mechanism which are matched with each other are arranged in the fixing frame through a linkage mechanism, and a fine adjustment mechanism is arranged at the top of the fixing frame. According to the eyelid distraction device, the adjusting distraction mechanism, the linkage mechanism and other structures are arranged, the adjusting distraction mechanism and the Airy beam mechanism synchronously move under the action of the linkage mechanism, the output end of the Airy beam mechanism is initially located at the center point of the adjusting distraction mechanism, and therefore after the upper eyelid and the lower eyelid are supported to be open through the adjusting distraction mechanism, the upper eyelid and the lower eyelid can be distrained. The Airy beam mechanism can accurately capture eyes, and the examination effect of the Airy beam mechanism is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic auxiliary devices, in particular to an upper and lower eyelid adjustment device for Airy beam coherent elastic imaging for conjunctival detection. Background technique [0002] Common diseases in ophthalmology clinics include ocular trauma, ocular chemical burns, thermal burn ocular trauma, acute angle-closure glaucoma, central retinal artery embolism, ocular radiation injury (electro-optic ophthalmia), endophthalmitis and ocular conjunctiva, etc. , In the detection, it is necessary to use the Airy beam coherent elastography technology to detect the eye, using the unique characteristics of the Airy beam, such as the beam shape invariance during the propagation process, along the "diffraction-free" propagation of curved trajectories in free space, "Self-acceleration" and self-recovery of the beam shape even after being obstructed by small objects, and "self-healing" make imaging convenient and a...

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide an Airy beam coherent elastography upper and lower eyelid adjustment device for conjunctival detection, to solve the problem that the Airy beam imaging machine in the prior art cannot accurately cooperate with the eyelid adjustment mechanism, thereby causing Airy beam The imaging effect of the imaging machine greatly affects the detection results; and when the eyelid adjustment mechanism is used, the existing technology uses the support force of the spring to stretch the upper and lower eyelids, which can easily cause secondary damage to the upper and lower eyelids, which affects the technical problems of treatment
