Optical coherence tomography scanner used for diagnosis in ophthalmology department

Abstract

The invention discloses an optical coherence tomography scanner used for diagnosis in the ophthalmology department. A fixed support is arranged on the right side of an optical coherence tomography scanner box and provided with a forehead bracket, an adjusting handle is fixedly connected to the right side wall of the optical coherence tomography scanner box through a fixing rod, a left fixed frameis arranged at the top of the adjusting handle, an upper supporting frame is arranged at the top of the left fixed frame, an upper spherical contact is arranged at the end, away from the left fixed frame, of the upper supporting frame, the adjusting handle is provided with a sliding groove, a sliding block is arranged in the sliding groove and connected with a right support, a lower supporting frame is arranged at the top end of the right movable support, and a lower spherical contact is arranged at the end, away from the right movable support, of the lower supporting frame. Through the optical coherence tomography scanner used for diagnosis in the ophthalmology department, the eye fatigue of a patient can be effectively relieved, when seeing a doctor, the diagnosis efficiency for the patient can be guaranteed, the high efficiency of diagnosis is improved, and the comprehensiveness of the diagnosis is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ophthalmology, in particular to an optical coherence tomography scanner for ophthalmology diagnosis. Background technique [0002] Optical coherence tomography is an interferometry method used to determine the scattering image of a sample along an optical coherence tomography beam, and optical coherence tomography can be divided into time domain and frequency domain. Optical coherence tomography (optical coherence tomography, Optical Coherence Tomography, OCT) is an imaging technology that has developed rapidly in the past decade. It uses the basic principle of weak coherent optical interferometer to detect Two-dimensional or three-dimensional structure images of biological tissues can be obtained by scanning the back reflection or several scattered signals of weakly coherent light. In the prior art, optical coherence tomography has been widely used to scan the patient's retina for medical diagnosis. Dur...

Problems solved by technology

In the prior art, optical coherence tomography has been widely used to scan the patient's retina for medical diagnosis. During the diagnosis process, because the patient's eyes cannot look directly at the lens for a long time, the eyelids cannot be completely
