Abstract

The invention relates to a detection device, in particular to a three-dimensional optical coherence elastography detection device applied to a corneal refractive operation. The invention aims to provide the three-dimensional optical coherence elastography detection device applied to the corneal refraction operation, the device can prevent a convex lens from being contaminated by impurities and is relatively high in working efficiency. The three-dimensional optical coherence elastography detection device applied to the corneal refraction operation comprises a detection box body, buffer bases, a shading cover plate, a protection cover and a start button. The multiple buffer bases are arranged at the bottom of the detection box body at intervals, the shading cover plate is arranged on one side of the top of the detection box body, the protection cover is arranged on one side of the detection box body, and the start button is arranged on one side of the upper portion of the detection box body. According to the three-dimensional optical coherence elastography detection device applied to the corneal refraction operation, through cooperation of a material conveying mechanism and a detection mechanism, a convex lens can be automatically conveyed and subjected to light transmittance detection, people do not need to hold the convex lens with hands, and light transmittance detection is prevented from being affected.

Description

technical field [0001] The invention relates to a detection device, in particular to a three-dimensional optical coherent elastic imaging detection device applied to corneal refractive surgery. Background technique [0002] Optical coherent elastography is a technology that takes elastic parameters such as Young's modulus, shear modulus, stress and strain of soft tissue as the imaging object. Along with the development of optical coherence tomography (OCT), optical coherence elastography (OCE) has been favored by people due to its micron-level resolution, real-time image processing and non-invasive imaging. For corneal refractive surgery, real-time image processing and analysis are required, so the use of optical coherence elastography is inevitable. [0003] At present, in corneal refractive surgery, the convex lens is a common optical element. In order to better observe the image, it is necessary to test the light transmission of the convex lens. When people test the ligh...
