Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to an ophthalmic optical coherence tomography scanner. Background Art

[0002] Optical coherence tomography, abbreviated as OCT, is a device that uses optical principles to perform diagnostic imaging. It can provide cross-sectional images of the retina and is used for objective quantitative measurement and qualitative clinical analysis when detecting glaucoma and retinopathy. The patient's head needs to be positioned during the use of the scanner, and the distance between the forehead and jaw of different patients is different, which reduces the comfort of positioning. In addition, during the detection process, the position of the optical lens assembly needs to be moved to detect both eyes. Long-term movement of the optical lens assembly will cause the assembly to loosen or be damaged due to factors such as vibration.

[0003] For example, announcement number CN111643049A discloses an ophthalmic optical coherence tomography scanner and an eye scanning image acquisition method, which include a controller, a base, a driving mechanism disposed on the base, and an optical head assembly disposed on the driving mechanism, wherein an iris camera group is installed on the optical head assembly.

[0004] It can be seen from the above-mentioned public scheme that the positions of the forehead rest and the chin rest are fixed, and the movement of the optical lens assembly needs to be controlled during detection, which will shorten its service life. In addition, the forehead rest and the chin rest with fixed spacing may not be suitable for all patients when used, reducing the comfort of use. Utility Model Content
